Technology and Application of Fieldbus Control System ---------IntelligentEquipment & Measurement And Control System Based on DeviceNetPromoted by the new technological revolution that automation control technology is tending digitization and internet in the field of automation industry, Shanghai Aton Electric Co., Ltd. developed Intelligent Equipment & Measurement And Control System Based on DeviceNet as a high and new technology industrialization model project. It was a state hi-tech development project of 2000 and was approved by the State Committee of Technology. Shanghai Aton Electric Co., Ltd. constructed production line of intelligent controller of pump and valve, relying on Shanghai Electric (Group) Corporation; constructed measurement and control system FCS R&D center of intelligent controller of pump and valve and built up mass production R&D basis, cooperating with Shanghai Jiaotong University and Shanghai University; constructed FCS remote diagnosis and service center of intelligent controller of pump and valve; constructed FCS training center of intelligent controller of pump and valve; founded mass production R&D basis along with the Rockwell Laboratory of Shanghai Jiaotong University and CIMS Center.1 Summary(1)Fieldbus control system is a system applied to field of production and microcomputerized measurement control equipment to realize both-way multinode serial communications. It is also called low-level control network for open, digital and multiplespot communications.Application: Flow Control System of Manufacturing; Process Control System; Traffic Control & Management; Building Automation. Features: Fieldbus control system is low-level low-bandwidth digital communication and control network in industrial system as well as open system connecting microcomputerized appearance. Intelligent instrument and controller are equal to microcomputer. They make up network with Fieldbus control system as the links to complete digital communication and other tasks.(2)Difference between FCS and DCS,FCS is updated control system after DCS integrated with digital control system and distributing control system. It solves the problem that in traditional DCS, devices made by different manufacturers cannot be connected. They can't realize exchange and operation to organize an network system with wider range of information sharing. It conquers the defect that special closed system for network should be used for communication in DCS to realize various functions of integrated automation. It turns the distributing structure combiningconcentration with deconcentration in DCS into new-type full distributing structure. It releases the control function to the field thoroughly and makes it possible to realize basic control function by means of fieldbus equipment itself. FCS breaks the traditional structure form of control system. The traditional analog control system adopts one-to-one equipment tie-wire and puts up connections respectively according to control loop. FCS adopts intelligent field equipment to place the control module, all input/output modules that used to be in the control chamber of DCS into field equipment. Since field equipment has ability to communicate, the field measuring and transferring instruments can transfer signals to actuating mechanism such as valve directly. Its control function can be fulfilled directly on the spot independent of the computer or control meter in the control chamber, which realizes thorough decentralized control.FCS adopts digital signals to replace analog signals so that multiple signals (including multiple operating parameter values, device status and failure information) can be transferred on a pair of cables. Meanwhile, it can give power supply to several devices. No switched block for analog/digital or digital/analog is needed besides fieldbus.(3)Characteristics of FCS●Open System;●Interoperability;● replace ability of devices made by different manufacturers.● Intelligentize and Autonomy;●Field equipment completing basic functions of automatic control.●Decentralized System Structure;●Field Adaptability;●Relatively Strong Interference Killing Feature and Safety●Intelligentized local equipment can save investment and quantity of hardware●Saving installation expenses and cables●Saving daily maintenance expenses●Enhancing accuracy and reliability of system●Enhancing initiativeness of system integration for users(4)Development Background and Trend of Fieldbus Control System,With the rapid development of computer and computer network, FCS has been rapidly developed as the interlinked communication network between the field intelligentdevices in the field of process automation, building and traffic etc. Because FCS meets the needs that industrial control system is developing in the way of decentralization, network and intellectualized, it has become the focus of global industrial automation and been universally concerned by the whole world. FCS has caused great revolutions on the aspects of system structure and function system for the current production of automation instrument, distributing control system and programmable controller. It is predicted that FCS will be the general trends in a very long time in the future fore sure.2 APPLICATION OF RELAYThe product reliability generally refers to the operating reliability. It is defined as: the ability of accomplishing the specified function under prescribed conditions and in prescribed time. It consists of intrinsic reliability and application reliability. The intrinsic reliability is determined by product designing and manufacturing technique, and the application reliability is concerned with the correct application of users and the services provided by the manufacturer before and after selling. When using relay, the user should pay attention to the following items.2.1 Coil applied voltageIt is best to choose the coil applicative voltage according to the rated voltage in design, or choose the voltage according to the temperature rising curve. Using any coil voltage that is less than the rated voltage will affect the operation of the relay. The coil operating voltage refers to the voltage that is applied between the coil terminals. The voltage value between the two terminals must be guaranteed, especially when using enlargement circuit to energize the coil. Whereas, it will also affect the relay characteristics if the applied voltage exceeds the highest rated voltage. Exorbitant voltage will bring exorbitant coil temperature rising, especially in high temperature ambient. Exorbitant temperature rising will damage the insulating material and affect the working safety of relay. For magnetic latching relay, energizing (or return) pulse width should not less than 3 times of the operating (or return) time, otherwise, the relay would be left on the middle-position state. When using solid-state components to energize the coil, the components dielectric strength must be above 80V, and the leakage of current must be as little as possible to ensure the relay to release.Energizing power source: Under 110% of the rated current, the adjusting ratio of the power source is less than 10% (or the output impedance is less than 5% of the coilimpedance), the wave voltage of the DC power source is less than 5%. The AC wave is sine wave; the waviness coefficient is between 0.95~1.25; wave distortion is within ±10%; the frequency change is within±1Hz or ±1% of the specified frequency (choosing the bigger value). The output power should not less than coil power consumption.2.2 Transient suppressionAt the moment when the coil power is stopped, peak-inverse voltage that is more than 30 times of the coil rated voltage is produced on the coil, which is harmful to the electronic circuit. Generally, the peak-inverse voltage is suppressed by transient suppression（cutting-peak）diode or resistance to limit the peak-inverse voltage within 50V. But the diode in parallel connection will delay3~5 times of the release time. If the request of the release time is high, a suitable resistance in series can be putted with and at one end of the diode.The power supply to relays in parallel connection and series connection,When several relays in parallel connection are supplied, the relay that the peak-inverse voltage is higher will release power to the relays that the peak-inverse voltage is lower. The release time of the relay will delay. So the relays in parallel connection should be controlled separately to eliminate mutual influence.The relays with different coil resistance and power can’t be used in series, otherwise, t he relay that the coil current is higher in the series circuit can’t operate reliably. Only the relays of the same specification can be used in series, but the peak-inverse voltage will be increased and the peak-inverse voltage should be suppressed. Resistance in series can be used to bear the part voltage that exceeds the rated voltage of the coil according to the ratio of the divided voltage.2.2.1 Contact loadThe load applied to the contacts should be accordant to the rated load and characteristics of the contacts. A load that is not applied according to the rated value range will cause problem. The relay that is only suitable for DC load can’t be used in AC occasions. The relay that can switch 10A load can’t always reliably operate in low level load (less than 10m A×6A) or in dry circuit occasions. The relay that can switch single-phase AC power source isn’t always suitable to switch two single-phase AC loads that aren’t synchronous; the relay that is only specif ied to switch the load of AC 50Hz（or 60Hz）can’t be used to switch AC load of 400Hz.2.2.2 Parallel and series connection of contactsThe contacts used in parallel connection can’t increase the load current, because the operating times of several sets of contacts are absolutely different; that is to say, there is still only a set of contacts switching the increased load. This would damage or weld the contacts and make the contacts can’t close or open. The parallel connection of the contacts can decrease t he misplay of “break”. But the parallel connection of the contacts would increase the misplay of “freezing”. Because the misplay of “break” is the main pattern of invalidation of contacts, the parallel connection can increase the reliability and can be used on the pivotal part of equipments. But the applied voltage should not exceed the highest operating voltage of the coil and should not less than 90% of the rated voltage, otherwise, the coil life and the applicative reliability would be damaged. The series connection of the contacts can increase the load voltage. The amount of the contact sets is equal to the times that the load voltage can be increased. The series connection of contacts can decrease the misplay of “freezing”, but it would increase the mis play of “break”. Anyway, when using redundant technology to increase the operating reliability of contacts, the characteristics and size and the failure mode of load must be considered.2.2.3 Switching speedThe switching speed should not exceed the reciprocal of 10 times of the sum of operating and release time (times/s), otherwise, the contacts can’t switch on steadily. Magnetic latching should be used under the pulse width specified in the technique criterion, or the coil may be damaged.3 RVT DISTRIBUTING ELECTRICITY INTEGRATE TESTAPPARATUSBasic functionMeasure asupervision:Three mutually electric voltage/electric current/ power factor with a great achievement/ power without a great achievement/electricity with a great achiverment/electricity/homophonic-wave electric voltage/ homophonic-wave electric/ current Day electric voltage/ electric current biggest and minimum value/fire for the failure Electric voltage over top, the limit/ lack mutually of time homophonic-wave analyzes is up to 13 times.The data is stored for 2 months.The data communicateRS232/485 communicating connect，The way in communicating can adopt the spot communicating or the long range communicating.，Possible to settle invoke orthe solid hour invokes, responding to the modification and long ranges control of the parameter.Without power compensationTaking physics measures as the power factor without a great achievement,the power factor with a great achievement and the dull place without power compensation;Y+ the combination method of the △，Y+ the △connects the line method，Y+ △ , Y, the △ connects the line method.Data managementAccording to WINDOW98 operation terrace, data in communication automatically reports born statement, curve and pillar form diagrams.Circulation of the protectionWhen the charged barbed wire net of mutually electric voltage over press, owe to press, and a super limit hour fast cut off in expiation of capacitor，When the charged barbed wire net lacks mutually or super limit in the preface of zero hour fast cut off in expiation of capacitor.screen manifestationChinese operation interface，Adopt 128*64 the back light liquid crystal display.The solid hour shows the charged barbed wire net relevant parameter.view manifestation to place the parameter.现场总线控制系统的技术和应用随着新的科学技术革命的出现，在自动化工业领域中，自动控制技术的发展趋向于数字化和网络互联化。

附录1外文翻译（原文）Systems An alysis and Desig nWorking under control of a stored program, a computer processes data into information. Think about that definition for a minute. Any given computer application invoIves at least three components: hardware, software, and data. Merely writing a program isn't eno ugh; because the program is but one comp onent in a system.A system is a group of components that work together to accomplish an objective. For example, con sider a payroll system. Its objective is pay ing employees. What components are invoIved? Each day employees record their hours worked on time cards. At the end of each week, the time cards are collected and delivered to the computer cen ter, where they are read in to a payroll program. As it runs, the program accesses data files. Fin ally, the paychecks are prin ted and distributed. For the system to work, people, procedures,input and output media, files, hardware, and software must be carefully coordinated. Note that the program is but one component in a system.Computer-based systems are developed because people n eed in formati on. Those people, called users, gen erally know what is required, but may lack the expertise to obta in it. Tech ni cal professi on als, such as programmers, have the expertise, but may lack training in the user's field. To complicate matters, users and programmers often seem to speak differe nt Ian guages,lead ing to com muni cati on problems. A systems analyst is a professional who translates user needs into technical terms, thus serving as a bridge betwee n users and tech ni cal professi on als.Like an engin eer or an architect, a systems an alyst solves problems by comb ining solid tech ni cal skills with in sight, imag in ati on, and a touch of art. Gen erally, the an alyst follows a well-defi ned, methodical process that in cludes at least the followi ng steps;1. Problem defi niti on2. A nalysis3. Desig n4」m pleme ntatio n5.Ma intenanceAt the end of each step, results are docume nted and shared with both the user and the programmers. The idea is to catch and correct errors and misunderstandings as early as possible. Perhaps the best way to illustrate the process is through example.Picture a small clothi ng store that purchases mercha ndise at wholesale, displaysthis stock, and sells it to customers at retail. On the one hand, too much stock represe nts an unn ecessary expe nse. On thither hand, a poor selecti on discourages shoppers. Ideally, a bala nee can be achieved: eno ugh, but not too much.Complicating matters is the fact that inventory is constantly changing, with customer purchasesdeplet ing stock, and retur ns and reorders add ing to it. [1] The owner would like to track inventory levels and reorder and given item just before the store runs out. For a single item, the task is easy-just count the stock-on-hand. Unfortunately, the store has hundreds of different items, and keeping track of each one is impractical. Perhaps a computer might help.2-1 Problem Defini tio nThe first step in the systems analysis and design processis problem definition. The an alyst's objective is determ ining what the user (in this case, the store's owner) needs. Note that, as the process begins, the user possesses the critical information, and the analyst must listen and learn. Few users are technical experts. Most see the computer as a "magic box, "and are not concerned with how it works. At this stage, the an alyst has no bus in ess eve n thinking about programs, files, and computer hardware, but must com muni cate with the user on his or her own term.The idea is to en sure that both the user and the an alyst are thinking about the same thi ng-Thus, a clear, writte n stateme nt express ing the an alyst's un dersta nding of the problem is essential. The user should review and correct this written statement. The time to catch misunderstandings and oversights is now, before time, money and effort are wasted.Often, following a preliminary problem definition, the analyst performs a feasibility study. The study a brief capsule version of the entire systems analysis and desig n process, attempts to an swer three questi ons:1. Ca n the problem be solved?2. Can it be salved in the user's environment?3. Ca n it be solved at a reas on able cost?If the answer to any one of these questions is no, the system should not be developed. Given a good problem definition and a positive feasibility study, the an alyst can tur n to pla nning and develop ing a problem soluti on.2- 2 An alysisAs an alysis beg ins, the an alyst un dersta nds the problem. The next step is determ ining what must be done to solve it. The user knows what must be done 1 during analysis; this knowledge is extracted and formally documented. Most users think interms of the functions to be performed and the data elements to be manipulated. The objective is to identify and link these key functions and data eleme nts, yield ing a logical system desig n.Start with the system's basic functions. The key is keeping track of the stock- on-ha nd for each product in inven tory .Inven tory cha nges becausecustomers purchase, excha nge, and retur n products, so the system will have to process customer tran sacti ons. The store's owner wants to selectively look at the inven tory level for any product in short supply and, if appropriate, order replacement stock, so the systemGive n the system's basic functions, the an alyst's n ext task is gaining a sense of their logical relati on ship. A good way to start is by describ ing how data flow betwee n the functions. As the name implies, data flow diagrams are particularly useful for graphically describ ing these data flows. Four symbols are used (Fig. 1). Data sources and dest in ati ons are represe nted by squares; in put data en ter the system from a source, and output data flow to a destination. Once in the system, the data are manipulated or cha nge by processes,represe ntedby roun d-cor ner recta ngles. A process might be a program, a procedure, or any thi ng else that cha nges or moves data. Data can be held for later process ing in data stores, symbolized by ope n-en ded recta ngles. A data store might be a disk file, a tape file, a database, written notes, or even a person's memory. Fin ally, data flow betwee n sources, dest in ati ons, processes, end data stores over data flows, which are represe nted by arrows.Figure 2 shows a prelimi nary data flow diagram for the inven tory system. Start with CUSTOMER. Transactions flow from a customer f into the system, where they are han dled by Process tran sacti on. A data store, STOCK, holds data on each item in inventory. Process transaction changes the data to reflect the new transaction. Mean while, MANAGEMENT accesses the system through Com mun icate, evaluat ing the data in STOCK and, if necessary, requesting a reorder. Once, a reorder is authorized. Gen erate reorder sends n ecessary data to the SUPPLIERwho ships the items to the store. Note that, because the reorder represents a change in the inventory level of a particular product or products it is han dled as a tran sacti on.The data flow diagram describes the logical system. The next step is tracing the data flows. Start with the destination SUPPLIER. Reorders flow to suppliers; for example, the store might want 25 pairs of jeans. To fill the order, the supplier needs the product description and the reorder quantity. Where do these data elements come from? Since they are output by Gen erate reorder, they must either be In put to or gen erated by this process. Data flow into Gen erate reorder for STOCK; thus, product descripti ons and reorder qua ntities must be stored in STOCK.Other data eleme nts, such as the item purchaseda nd the purchase qua ntity are gen erated by CUSTOMER. Still others, for example selli ng price and reorder point, are gen erated by or n eeded by MANAGEMENT. The curre nt stock-on-ha nd for a give n item is an example of a data eleme nt gen erated by an algorithm in one of the procedures. Step by step, methodically, the an alyst ide ntifies the data eleme nts to be in put to .stored by, mani pulated by, gen erated by, or output by the system.To keep track of the data elements, the analyst might list each one in a data dicti on ary. A simple data dicti onary can be set up on in dex cards, but computerized data dicti on aries have become in creas in gly popular. The data dict ion ary, a collect ion of data describing and defining the data, is useful throughout the systems analysis and desig n process, and is ofte n used to build a database duri ng the impleme ntati on stage.The idea of analysis is to define the system's major functions and data elements methodically. Remember that the objective is tran slati ng user n eeds into tech ni cal terms. Since the system starts with the user, the first step is defining the user's needs. Users think in terms of functions and data. They do not visualize programs, or files, or hardware .and during this initial, crucial analysis stage it is essential that the analyst think like a user, not like a programmer.Data flow diagrams and data dicti on aries are useful tools. They provide a format for record ing key in formati on about the proposed system. Also, they jog the an alyst's memory) for example, if the an alyst does n't have sufficie nt in formatio n to complete a data dictionary entry, he or she has probably missed something. Perhaps most importantly, the data flow diagram and the data dictionary document the analyst's un dersta nding of the system requireme nts. By review ing these docume nts, the user can correct misun dersta ndings or oversights. Fin ally, they represe nt an excelle nt start ing point the n ext step, desig n.2-3 Desig nAs we en ter the desig n stage, we know what the system must do, and thus can beg in thi nking about how to do it. The objective is to develop a strategy for sol ving the problem. At this stage, we are not interested in writing code or in defining precise data structures; in stead, we want to ide ntify, at a black box level, n ecessary programs, files, procedures, and other comp onen ts.The data flow diagram defi nes the system's n ecessary fun cti ons; how might they be implemented? One possibility is writing one program for each process. Another is combi ning two or more processes in a sin gle program; there are doze ns of alter native solutions. Let's focus on one option and document it.A system flowchart uses symbols to represent programs, procedures, hardware devices, and the other comp onents of a physical system (Fig. 3). Our flowchart (.Fig. 4) shows that tran sacti on data en ter the system through a termi nal, are processed by a data collection program, and then are stored on an inventory file. Eventually, the inventory processed by a Report and reorder program. Through it, management man ipulates the data and authorizes reorders.Fig. 4 on a system flowchart, symbols represe nt programs, procedures, hardware devices, and the other comp onents of a physical system.Fig 3Look at the system flowchart. It identifies several hardware components, in clud inga computer, a disk drive, a data entry term in al, a prin ter, and a display termi nal. Twoprograms are n eeded;Process tran sact ion and Report and reorder. I n addition to thehardware and the programs, we'll need data structures for the inventory for data flawsbetween the I/O devices and the software. Note that this system flowchart illustrates onepossible solution; a good analyst will develop several feasible alter natives before choosing one.The flowchart maps the system, highlighting its major physical components. Since the data linkthe components, the next task is defining the data structures. Consider, for example, the inventoryfile. It contains all the data elements from the data store STOCK. The data eleme nts are listed in the data dicti on ary. Using them, the file's data structure can be pla nn ed.How should the organized? That depends on how it will be accessed.For example, in some applications, data are processedat regular, predictable intervals. Typically, the data are collected over time and processed together, as a batch. If batch process ing is acceptable, a seque ntial is probably和吃ram L / ar^1MmnjBirWe 加Connrtunlcaialinka Tcnmiin*l pointPunctwd详帕FTiniedoutput M 科Ml 也tSpB Ofiirw:MW*緘 昨1»1瞪dMbest.It is not always possible to wait until a batch of transactions is collected, however. For example, consider an air defense early warning system. If an unidentified aircraft is spotted it must be identified immediately the idea of waiting until 5 _ 00 p.m. because "that's whe n the air defe nse program is run" is absurd. In stead, because of the n eed for quick resp on se, each tran sact ion must be processed as it occurs. Gen erally such tran sact ion process ing systems call for direct access file.Our inventory system has two programs. One processestransactions. A direct access inven tory a reas on able choice. The other allows man ageme nt to study inven tory data occasi on ally; batch process ing would certa inly do. Should the inventory organized sequentially or directly? Faced with such a choice a good analyst considers both options. One possible system might accept transactions and process them as they occur. As an alter native, sales slips might be collected throughout the day and processed as a batch after the store closes. In the first system, the two programs would deal with direct access files; in the second system, they would be linked to sequential files. A program to process direct access data is differe nt from a program to process seque ntial data. The data drive the system. The choice of a data structure determines the program ' s structure. Note that the program is defi ned and pla nned in the con text of the system.2- 4 Impleme ntati onOnce the system's major comp onents have bee n ide ntified .we can beg in to develop them. Our system in cludes two programs, several pieces of equipme nt, and a number of data structures. During implementation, each program is planned and written using the techniques described in Chapter 7. Files are created, and their contents checked. New hardware is purchased, in stalled, and tested. Additi on ally, operating procedures are written and evaluated. Once all the component parts are ready, the system is tested. Assuming the user is satisfied, the finished system is released.2- 5 MaintenanceMaintenance beg ins after the system is released. As people use it, they will suggest minor improveme nts and enhan ceme nts.Occasi on ally, bugs slip through debug and testi ng, and rem oving them is ano ther maintenance task. Fin ally, con diti ons cha nge, and a program must be updated; for example, if the gover nment passes a low cha nging the procedure for collect ing in come taxes, the payroll program must be modified. Maintenance continues for the life of a system, and its cost can easily match or exceed the original development cost. Good planning, solid documentation, and well-structured programs can help to mini mize maintenance cost.附录 2 外文翻译（译文）系统的分析与设计在存储程序的控制下，计算机把数据处理成信息。

IntroductionE-commerce (E-Business) is in open networks, including between enterprises (B2B), business and consumers (B2C) commercial transactions, compared with the traditional business model, e-commerce with efficient, convenient, covered wide range of characteristics and benefits. However, e-commerce open this Internet-based data exchange is great its security vulnerabilities, security is a core e-commerce development constraints and key issues.In this paper, the basic ideas and principles of systems engineering, analyzes the current security threats facing e-commerce, in this based on security technology from the perspective of development trend of e-commerce.Ⅱ. E-commerce modelModern e-commerce technology has focused on the establishment and operation of the network of stores. Network in the department stores and real stores no distinction between structure and function, differences in their function and structure to achieve these methods and the way business operate.Web store from the front view is a special kind of WEB server. WEB site of modern multimedia support and a good interactive feature as the basis for the establishment of this virtual store, so customers can, as in a real supermarket pushing a shopping cart to select goods, and finally in the checkout check out. These online stores also constitute the three pillars of software: catalog, shopping cart and customer checkout. Customers use an electronic currency and transaction must store customers and stores are safe and reliable.Behind the store in the network, enterprises must first have a product storage warehouse and administration; second network to sell products by mail or other delivery channels to customers hands; Third, enterprises should also be responsible for product after-sales service, This service may be through networks, may not. Internet transactions are usually a first Pay the bill and getting goods shopping. For customers, convenience is that the goods purchased will be directly delivered to their home, but hard to feel assured that the goods can not be confirmed until the handsreach into their own hands, what it is.Therefore, the credibility of the store network and service quality is actually the key to the success of e-commerce.Ⅲ.the key to development of electronic commerceE-commerce in the telecommunications network to develop. Therefore, the advanced computer network infrastructure and telecommunications policy easing the development of electronic commerce has become a prerequisite. Currently, telecom services, high prices, limited bandwidth, the service is not timely or not reliable and so the development of e-commerce has become a constraint. Speed up the construction of telecommunications infrastructure, to break the telecommunications market monopoly, introduce competition mechanism to ensure fair competition in the telecommunications business, to promote networking, ensure to provide users with low-cost, high-speed, reliable communications services is a good construction target network environment, but also all of the world common task.E-commerce the most prominent problem is to solve the on-line shopping, trading and clearing of security issues, including the establishment of e-commerce trust between all the main issues, namely the establishment of safety certification system (CA) issues; choose safety standards (such as SET , SSL, PKI, etc.) problems; using encryption and decryption method and encryption strength problems. Establishment of security authentication system which is the key.Online trading and traditional face to face or written transactions in different ways, it is transmitted through the network business information and trade activities. The security of online transactions means:Validity: the validity of the contract to ensure online transactions, to prevent system failure, computer viruses, hacker attacks.Confidentiality: the content of the transaction, both transactions account, the password is not recognized by others and stealing.Integrity: to prevent the formation of unilateral transaction information and modify.Therefore, the e-commerce security system should include: secure and reliable communications network to ensure reliable data transmission integrity, prevent viruses, hackers; electronic signatures and other authentication systems; complete data encryption system and so on.Ⅳ.e-commerce security issues facingAs e-commerce network is the computer-based, it inevitably faces a number of security issues.(1) Information leakPerformance in e-commerce for the leakage of business secrets, including two aspects: the parties are dealing transactions by third parties to steal the contents; transaction to the other party to provide documents used illegal use by third parties.(2) AlteredE-commerce information for business performance in the authenticity and integrity issues. Electronic transaction information in the network transmission process may be others to illegally modify, delete or re-changed, so that information about its authenticity and integrity.(3) IdentificationWithout identification, third-party transactions is likely to fake the identity of parties to a deal breaker, damage the reputation of being counterfeit or stolen by one party to the transaction fake results and so on, for identification, the transaction between the two sides can prevent suspicion situation.(4) Computer virusesComputer virus appeared 10 years, a variety of new virus and its variants rapidly increasing, the emergence of the Internet for the spread of the virus has provided the best medium. Many new viruses directly using the network as its transmission, as well as many viruses spread faster through dried networks, frequently causing billions of dollars in economic losses.(5) HackerWith the spread of a variety of application tools, hackers have been popular, and are not in the past; non-computer expert can not be a hacker. Have kicked Yahoo's mafia boy did not receive any special training, only a few attacks to the users to download software and learn how to use the Internet on a big dry.Ⅴ.e-commerce security and safety factorsEnterprise application security is the most worried about e-commerce, and how to protect the security of e-commerce activities, will remain the core of e-commerce research. As a secure e-commerce system, we must first have a safe, reliable communication network, to ensure that transaction information secure and rapidtransmission; second database server to ensure absolute security against hackers break into networks to steal information. E-commerce security technologies include encryption, authentication technology and e-commerce security protocols, firewall technology.(A), encryption technologyTo ensure the security of data and transactions to prevent fraud, to confirm the true identity of transaction parties, e-commerce to adopt encryption technology, encryption technology is through the use of code or password to protect data security. For encrypted data is called plaintext, specifically through the role of a encryption algorithm, the conversion into cipher text, we will express this change as the cipher text is called encryption, the cipher text by the decryption algorithm to form a clear role in the output of this a process known as decryption. Encryption algorithm known as the key parameters used. The longer the key, the key space is large, traverse the key space the more time spent, the less likely cracked.Encryption technology can be divided into two categories: symmetric encryption and asymmetric encryption. Symmetric encryption to the data encryption standard DES (Data Encryption Standard) algorithm is represented. Asymmetric encryption is usually RSA (Rivets Shamir Aleman) algorithm is represented.(B), authenticationCommonly used security authentication technologies: digital signatures, digital certificates, digital time stamp, CA security authentication technology.(C), hacker protection technologyCurrently, hackers have become the biggest e-commerce security threats, thus preventing hacking network security technology has become the main content, by governments and industry are highly valued. Hacking techniques include buffer overflow attacks, Trojans, port scans, IP fraud, network monitoring, password attacks, and denial of service Dos attacks. At present, people have made many effective anti-hacker technologies, including firewalls, intrusion detection, and network security evaluation techniques.Ⅵ.the future security of e-commerceIncreasingly severe security problems, are growing threat to national and global economic security, governments have been based on efforts in the following areas: (1) Strengthen the legislation, refer to the advanced countries have effective legislation, innovative, e-commerce and improve the protection of the laws againstcyber-crime security system.(2) Establishment of relevant institutions, to take practical measures to combat cyber crime. Development of the law, the implementing agencies should also be used for its relevant laws, which must establish an independent oversight body, such as the executing agency to implement the law.(3) Increase investment in network security technology; improve the level of network security technology. E-commerce security law is the prerequisite and basis for development and secure e-commerce security technology is a means of protection. There are many security issues are technical reasons, it should increase the technology resources, and continuously push forward the development of old technologies and developing new security technology.(4) To encourage enterprises to protect themselves against Internet crime against. To avoid attack, companies can not hold things to chance, must attach great importance to system vulnerabilities, in time to find security holes to install the operating system and server patches, and network security detection equipment should be used regularly scan the network monitoring, develop a set of complete security protection system to enable enterprises to form a system and combined with the comprehensive protection system.(5) To strengthen international cooperation to strengthen global efforts to combat cyber crime. As e-commerce knows no borders, no geographical, it is a completely open area, so the action against cyber crime e-commerce will also be global. This will require Governments to strengthen cooperation, can not have "the saying which goes, regardless of others, cream tile" misconception.(6) To strengthen the network of national safety education, pay attention to the cultivation of outstanding computer.Ⅶ. ConclusionE-commerce in China has developed rapidly in recent years, but the security has not yet established. This has an impact on the development of electronic commerce as a barrier.To this end, we must accelerate the construction of the e-commerce security systems. This will be a comprehensive, systematic project involving the whole society. Specifically, we want legal recognition of electronic communications records of the effectiveness of legal protection for electronic commerce; we should strengthen the research on electronic signatures, to protect e-commerce technology; we need to build e-commerce authentication system as soon as possible, to organize protection for electronic commerce. Moreover, for e-commerce features without borders, we shouldalso strengthen international cooperation, so that e-commerce truly plays its role. Only in this way, we can adapt to the timesPromoting China's economic development; also the only way we can in the economic globalization today, to participate in international competition, and thus gain a competitive advantage.Source: Michael Hecker, Tharam S.

毕业设计（论文）外文翻译题目The problem of small and medium-sized enterprise informatization processproblems and countermeasures姓名学号 40741703系别科学技术系专业信息管理与信息系统指导教师2011年01月07日Information extraction system: design and itscommercial useAfter more than 30 years of development of the Information Extraction?(IE) system, it comes to be the focus of the attention of the researchers of information retrieval, database system and natural language processing. The reason is very simple. Because the traditional information search engine can only give the result of relevant pieces of documents and information users must read them by themself to check if the documents match their requirements or not, but the IE system give the facts directly to the users. The pressure of the information explosion makes it impossible to read all the documents, news or Internet pages to locate their interested facts. But all the facts are important for the information usersto make any decision. IE system can help them to archive the goal, which is to know all the things that happened in the domain which they are interesting. The Information Extraction system filters the great amounts of documents that were written in nature human language or formatted in semi-structured to get the useful description ofthe facts which are interested by the information users. The shallow parsing technology in sentence semantic analysis is the most popular method in the IE system. Most of IE systems use such technology to catch the information points in the text. Then, after post processing, such as co-reference analysis or repeated-facts clearing, all the filtered information points were put into slots of a well-structured template. All the filled templates combine the database which will be outputted. The output data can be read by human being or transfer to an automatic analysis program to process. During the research of the IE system, we know it is veryimportant to have the enough technology backup. The ability of nature language processing, large-scale programming system development and some very serious knowledge base, such as syntactic and semantic dictionary and tree-bank corpus are the necessary parts of the backup. Today, a practically large-scale Information Extraction system with the ability of easy domain-transformation is the main targetof the research of IE. In this thesis, firstly, the development of a prototype of universal Information Extraction system is described. The main features of this system are: 1) using shallow parsing technology with sentence semantic template to extract the information in the text; 2) Easy modular-expansion or exchange；3) multi-thread programming mechanics are used to improve the processing speed; 4) Chinese language is its working language. Secondly, the research of how the IE system to improve the enterprise information utilizing are also discussed. Today, many large Chinese enterprises use MIS, MRP-II or ERP system to improve their business management. The knowledge management technology is a very important aid to help the development of the enterprise. IE system can become the main part of the knowledge management system. Last part of this thesis is about how to build a proper business model for a practical IE system. Because of the fast development of the Internet, the basic information management technology, such as search engine, has become the base of a business empire. Yahoo is the most famous one. Does the IE technology can? I put forward my opinion that the IE system is avery useful and important information management tool in business but it can not be served as a search engine for public information user on the Internet recently. It can only run behind the scene and be controlled by human experts to collect information from the Internet. The collected information must takea post-process before it can be provided to the end user.企业信息化背景下的信息提取系统信息提取系统从诞生到现在已经大约30多年了，最近10年得到特别重视，并且成为信息检索系统、数据库系统以及自然语言处理系统发展的热门领域。

毕业设计外文文献翻译专业交通运输姓名张有节同组成员赖思琪杨鹏指导老师刘习华Campus Network planning and Construction At present, China's rapid development of the cause of the campus network, to early 2003, almost all colleges have set up their own campus network, and carry out a variety of its services and applications. Campus Network build a rich learning resources to enhance the efficiency of education. But as the number of users increased dramatically increased and the pattern of operations, campus network security is increasingly conspicuous, and the ever threat to the healthy development of the campus network, as an education development of the information industry should not be neglected problem. This paper focuses on the campus network design and the process of building the campus network established the goal of building, campus network technology programme design, information resources construction, application software development, network management and security, the five key issues. The campus network is the infrastructure of importance of school, taking the school teaching, research, managing and outward communicate many roles of etc..The safe condition of the campus net affects the teaching activity of the school directly.Set up in the network of initial stage, the safe problem may still be not outstanding, but along with applied thorough, various data of the campus net would nasty play increment, the safe problem beginning of various each kind perplexes us.The Internet flies to develop soon, to the campus network the teachers and the students' life and studies have already produced the profound influence, the network have already not have no place in our life at. But at enjoy the convenience that high technology bring at the same time, we need to be awake of know, the safe problem of network also become the network application more and more increasingly and seriously huge bar, the situation that the campus network safety hazes already arrived and must unify the management and resolve thoroughly, only good resolve the safe problem of network, the application of the campus network then can be healthy, high speed of development. We should consider the comprehensive usage fire wall and encrypt several measures, such as technique and the anti-virus software...etc. completely, work in coordination, strengthening the management, looking for thebalance point of insure the network safety and the network efficiency from it, the safety of the comprehensive exaltation campus network, thus build up rise a set of real in keeping with safe system of the calculator network of the school.The time today's knowledge-based economy and information technology have the development and popularization of Internet in the world have decided the time the network will become the main tool for information. With the development of computer network technology, network has become an important platform for the exchange of information. Internet-based e-learning with time-sensitive, shared, interactive and many of the characteristics of the individual, so it has a traditional teaching model of unmatched advantages. It created a new teaching model, breaking the traditional teaching model at the time and space limitations, the use of advanced teaching methods and teaching methods, greatly improve the teaching efficiency and teaching effectiveness, teaching and learning activities to enable a new level. Do a good job in the design of the campus network, are among the schools, both internal and external communication between the key and convenient.21st century the size of the campus network and application level are reflected in schools and science teaching and learning environment an important component of the force, so we should make use of existing campus conditions, design a secure, unified campus network.Large Campus Network DesignBusinesses operating large campus networks are increasingly looking for infrastructure upgrades to:(1) Handle high bandwidth applications such as voice, video, and IP multicast Improve backbone capacity for shared Ethernet or FDDI campus backbones(2) Support applications based on Novell IPX, DECNET, AppleTalk, and SNA(3) Offer high availability, performance, & manageability for your company's intranet.Use Layer 2, Layer 3, or ATM backbone solutions to expand your large campus network. In typical designs, the buildings or different parts of the campus connect together across a high performance, switched backbone. Network redundancy andhigh availability is provided at each layer. A high capacity, centralized server farm provides resources to the campus, and when combined with Cisco IOS, network management strategies support QoS, security, troubleshooting, and other common management features from end to end.Medium Campus Network Design A medium campus consists of one large building or several buildings. Networking for a medium campus is designed for high availability, performance, and manageability. This is also called a 'collapsed backbone' design for medium campus networks. Additional requirements of these designs typically include:(1) High performance and availability for bandwidth applications such as voice, video, and IP multicast(2) Shared Ethernet or FDDI building backbone which is running out of capacity(3)Support for applications based on Novell IPX, DECNET, AppleTalk, and SNA Based on the Cisco A VVID architecture, these intelligent network platforms and products provide the basis for a complete network solution.Small campus networks DesignIn most cases, network redundancy is not the top priority, but cost effectiveness is. Additional requirements of these designs typically include:(1) High performance and availability for bandwidth applications such as voice, video, and IP multicast(2) Shared Ethernet or FDDI building backbone which is running out of capacity(3) Support for applications based on Novell IPX, DECNET, AppleTalk, and SNA校园网的规划与构建目前，我国校园网事业飞速发展，至2003年初，几乎所有的大中专院校都建立了自己的校园网，并在其上开展了多种服务和应用。

Governmentsupport for small and medium sized enterprise informatization construction is not enough, insufficient guidance, mainly reflected in the following two aspects: first, large enterprises is present at all levels of Government Informatization Transformation of special funds focus on the funding, and the informatization construction of small and medium sized enterprises lack of attention; the, government departments themselves in the process of information did not take the lead, such as lack of the information-based degree of the industrial and commercial bureau, tax bureau, making every month the company but also to the Inland Revenue Department ranked team for a long time to make statements and so on, which in a certain extent, affected the enthusiasm of the informatization construction of small and medium sized enterprises.2) The relevant laws and regulations are not perfect. At present our country in theinformation construction of enterprises is still not unified planning and standards, the corresponding laws and regulations are not perfect, the informatization construction of the regional industry basically in a state of fragmentation. For the network economic crimes, China is also lack of effective technical means and legal sanctions basis, so the first use of information technology companies to pay the price is relatively large. So many small and medium enterprises in the face of dazzling computer hardware and software market and numerous information systems development failures phenomenon, many confused, indecisive.3) Services Limited, the environment is poor. Compared with foreign countries, thedevelopment of China's software industry is lagging behind. On the market a lot of enterprise information solutions are provided by foreign large software companies, such as SAP, the United States, the United States, and so on.However, these programs are very expensive, small and medium enterprises can not afford to buy. Although there are a lot of Domestic Company for small and medium enterprises to provide the so-called tailored management software products, the price is not expensive, but the software can not meet the actual needs of small and medium enterprises, service has not kept up with. In addition, the small and medium enterprises in the construction of information technology has expertise in consulting company, the construction of information technology is not enough, leading to the project quality can not be guaranteed. Electronic payment, information security, social credit system and other aspects of the existing problems that the enterprise believes that now is not the best time to carry out information.3.1 Enterprise1) Correct understanding of informationThe rapid development in information technology today economic globalization pace accelerate, make enterprise information construction becomes the trend of the times to be a trend which cannot be halted. Information process, which is to integratethe various resources within the enterprise through the computer network technology, optimize the management process, and then improve the process of economic efficiency and competitiveness of enterprises. Enterprise information is not equal to the simple computer, it is a complex process. Only business process reengineering, so that information technology into the enterprise's financial, sales, planning, production, procurement and other business processes, or else simply do not talk about what the enterprise information.2) Accelerate composite information talentsEnterprises should establish corresponding mechanism cultivate and maintain a technology to improve the team all staff and managers in the management of information technology knowledge and theory level. Talents are the most valuable resources for enterprises. In order to promote the development of information technology, small and medium enterprises must do a good job in both hands. On the one hand, enterprises must formulate human resource strategy, adopt various methods and means to recruit and introduce talents for enterprises, especially the advanced technology. On the other hand, enterprises should carry out more training activities within the enterprise, through technical exchanges and cooperation and other ways to cultivate a large number of professional knowledge, with practical ability of information technology personnel, improve the comprehensive ability of the enterprise to improve the normal operation of enterprise information.3) Take the key breakthrough of phased implementationEnterprise information is a step is not possible nor practical, should take steps to implement, key breakthrough system construction mode, can be divided into several different stages to implement it step by step. As small and medium-sized enterprises, by their own limitations, can input information construction funds will not too much.4) Plays by society and government supportOur country small and medium-sized enterprise information is still in its infancy, is inseparable from the government’s guidance and social S s m u o a r n t d.medium enterprise informationization is a revolution ,is a complex and arduous systemproject ,involving all aspects of the business small and medium-sized enterprise informatization level is directly related to the level of the whole national informatization level. Small and medium-sized enterprises want to survive and develop, infromatization construction to be imperative informatization construction of small and medium-sized enterprises to obtain the competitive advantage will become the inevitable choice.5) To make the overall planning of enterprise informationEnterprise information planning, also known as enterprise IT planning, it is the guidance of enterprise development strategy, diagnosis and analysis of enterprise management status, optimize the business process, and put forward the enterprise information system architecture, determine the logic relationship between each part of the information system. In the preparation of enterprise information construction, the research on the status quo and future development of enterprises should be made, including a series of complete planning including enterprise information network, technical route, the choice of software, implementation and consulting team, information realization steps and so on.3.2 government and social aspects1) To strengthen the policy support to the informatization construction of small andmedium sized enterprises.To give full play to the role of the national enterprise information work leading group and local business information work leading group, all levels of government information technology to reform the special funds also have a certain tilt, adhere to the policy of the government to promote, market guidance, business entities, industry breakthrough, regional expansion, and strengthen enterprise information engineering support, and provide more effective macro guidance, organization and policy support.2) To create a good legal environment. Governments at all levels should developinformation management regulations as soon as possible,Strengthen the management of information resources. In order to solve theproblem of security and electronic contract authentication of online transactions and settlement, online contract law should be introduced as soon as possible to enhance the security of online transactions. To strengthen the laws and regulations on the fight against Internet crimes and to strengthen the protection of intellectual property rights. At the same time, we should further improve the information security monitoring system, establish an effective mechanism for information security and emergency handling mechanism, in the focus on the protection of basic network and important system security based on comprehensive information security protection.3) To strengthen the information guidance, play the role of the third party resourcesand platform.Small and medium enterprise information is still in the enlightenment, need to actively cooperate with the full range of positive guidance. Government to play the role of policy guidance to play the role of enterprise information, the media should play an active role in promoting and promoting the role of. At the same time, we should give full play to the role of the third party resources and platform. If the enterprise from the construction of network platform, run the server group, support a team to start, really need a high input. But in fact, they can outsource these operations, the business can only focus on the core business process. The use of third party platform to establish supply management system, often can achieve the goal of low cost, high efficiency, dynamic, very worthy of small and medium enterprises for reference.In recent years, the Chinese government has strengthened the guidance and promotion of the small and medium-sized enterprise information, and has achieved some results. But from the level of development of information technology and Chinese enterprises to participate in the global competition point of view, is still a long way to go. The government should continue to increase support for small and medium-sized enterprises, accelerate the construction of information infrastructure and public information resources, accelerate the construction of small and medium enterprise information service team, and actively carry out e-government, so as to mobilize and encourage theimplementation of information technology in small and medium enterprises.企业信息化建设外文翻译文献:随着信息技术的飞速发展，国内、中小企业信息化建设进入了新的发展阶段，中小企业信息化已成为中小企业自身优势，提高竞争优势，增强竞争力和发展能力是一个重要的选择。

Governmentsupport for small and medium sized enterprise informatization construction is not enough, insufficient guidance, mainly reflected in the following two aspects: first, large enterprises is present at all levels of Government Informatization Transformation of special funds focus on the funding, and the informatization construction of small and medium sized enterprises lack of attention; the, government departments themselves in the process of information did not take the lead, such as lack of the information-based degree of the industrial and commercial bureau, tax bureau, making every month the company but also to the Inland Revenue Department ranked team for a long time to make statements and so on, which in a certain extent, affected the enthusiasm of the informatization construction of small and medium sized enterprises.2)The relevant laws and regulations are not perfect. At present our country in theinformation construction of enterprises is still not unified planning and standards, the corresponding laws and regulations are not perfect, the informatization construction of the regional industry basically in a state of fragmentation. For the network economic crimes, China is also lack of effective technical means and legal sanctions basis, so the first use of information technology companies to pay the price is relatively large. So many small and medium enterprises in the face of dazzling computer hardware and software market and numerous information systems development failures phenomenon, many confused, indecisive.3)Services Limited, the environment is poor. Compared with foreign countries, thedevelopment of China's software industry is lagging behind. On the market a lot of enterprise information solutions are provided by foreign large software companies, such as SAP, the United States, the United States, and so on.However, these programs are very expensive, small and medium enterprises can not afford to buy. Although there are a lot of Domestic Company for small and medium enterprises to provide the so-called tailored management software products, the price is not expensive, but the software can not meet the actual needs of small and medium enterprises, service has not kept up with. In addition, the small and medium enterprises in the construction of information technology has expertise in consulting company, the construction of information technology is not enough, leading to the project quality can not be guaranteed. Electronic payment, information security, social credit system and other aspects of the existing problems that the enterprise believes that now is not the best time to carry out information.3.Accelerating the information construction of small and medium-sizedenterprises measures3.1Enterprise1)Correct understanding of informationThe rapid development in information technology today economic globalization pace accelerate, make enterprise information construction becomes the trend of the times to be a trend which cannot be rmation process, which is to integratethe various resources within the enterprise through the computer network technology, optimize the management process, and then improve the process of economic efficiency and competitiveness of enterprises. Enterprise information is not equal to the simple computer, it is a complex process. Only business process reengineering, so that information technology into the enterprise's financial, sales, planning, production, procurement and other business processes, or else simply do not talk about what the enterprise information.2)Accelerate composite information talentsEnterprises should establish corresponding mechanism cultivate and maintain a technology to improve the team all staff and managers in the management of information technology knowledge and theory level.Talents are the most valuable resources for enterprises. In order to promote the development of information technology, small and medium enterprises must do a good job in both hands. On the one hand, enterprises must formulate human resource strategy, adopt various methods and means to recruit and introduce talents for enterprises, especially the advanced technology. On the other hand, enterprises should carry out more training activities within the enterprise, through technical exchanges and cooperation and other ways to cultivate a large number of professional knowledge, with practical ability of information technology personnel, improve the comprehensive ability of the enterprise to improve the normal operation of enterprise information.3)Take the key breakthrough of phased implementationEnterprise information is a step is not possible nor practical, should take steps to implement, key breakthrough system construction mode, can be divided into several different stages to implement it step by step. As small and medium-sized enterprises, by their own limitations, can input information construction funds will not too much.4)Plays by society and government supportOur country small and medium-sized enterprise information is still in its infancy, is inseparable from the government’s guidance and social support.Small and medium enterprise informationization is a revolution ,is a complex and arduous systemproject ,involving all aspects of the business small and medium-sized enterprise informatization level is directly related to the level of the whole national informatization level. Small and medium-sized enterprises want to survive and develop, infromatization construction to be imperative informatization construction of small and medium-sized enterprises to obtain the competitive advantage will become the inevitable choice.5)To make the overall planning of enterprise informationEnterprise information planning, also known as enterprise IT planning, it is the guidance of enterprise development strategy, diagnosis and analysis of enterprise management status, optimize the business process, and put forward the enterprise information system architecture, determine the logic relationship between each part of the information system. In the preparation of enterprise information construction, the research on the status quo and future development of enterprises should be made, including a series of complete planning including enterprise information network, technical route, the choice of software, implementation and consulting team, information realization steps and so on.3.2government and social aspects1)To strengthen the policy support to the informatization construction of small andmedium sized enterprises.To give full play to the role of the national enterprise information work leading group and local business information work leading group, all levels of government information technology to reform the special funds also have a certain tilt, adhere to the policy of the government to promote, market guidance, business entities, industry breakthrough, regional expansion, and strengthen enterprise information engineering support, and provide more effective macro guidance, organization and policy support.2)To create a good legal environment. Governments at all levels should developinformation management regulations as soon as possible,Strengthen the management of information resources. In order to solve theproblem of security and electronic contract authentication of online transactions and settlement, online contract law should be introduced as soon as possible to enhance the security of online transactions. To strengthen the laws and regulations on the fight against Internet crimes and to strengthen the protection of intellectual property rights. At the same time, we should further improve the information security monitoring system, establish an effective mechanism for information security and emergency handling mechanism, in the focus on the protection of basic network and important system security based on comprehensive information security protection.3)To strengthen the information guidance, play the role of the third party resourcesand platform.Small and medium enterprise information is still in the enlightenment, need to actively cooperate with the full range of positive guidance. Government to play the role of policy guidance to play the role of enterprise information, the media should play an active role in promoting and promoting the role of. At the same time, we should give full play to the role of the third party resources and platform. If the enterprise from the construction of network platform, run the server group, support a team to start, really need a high input. But in fact, they can outsource these operations, the business can only focus on the core business process. The use of third party platform to establish supply management system, often can achieve the goal of low cost, high efficiency, dynamic, very worthy of small and medium enterprises for reference.4.ConclusionIn recent years, the Chinese government has strengthened the guidance andpromotion of the small and medium-sized enterprise information, and hasachieved some results. But from the level of development of informationtechnology and Chinese enterprises to participate in the global competition point of view, is still a long way to go. The government should continue to increasesupport for small and medium-sized enterprises, accelerate the construction of information infrastructure and public information resources, accelerate theconstruction of small and medium enterprise information service team, andactively carry out e-government, so as to mobilize and encourage theimplementation of information technology in small and medium enterprises.译文：中小企业信息化建设分析沃斯利-苏珊【摘要】:随着信息技术的飞速发展，国内、中小企业信息化建设进入了新的发展阶段，中小企业信息化已成为中小企业自身优势，提高竞争优势，增强竞争力和发展能力是一个重要的选择。
