英文文献资料（一）Clusters and the New Economics of CompetitionMichael E. Porter（Harvard university）Why Clusters Are Critical to CompetitionModern competition depends on productivity, not on access to inputs or the scale of individual enterprises.Productivity rests on how companies compete,not on the particular fields they compete panies can be highly productive in any industry–shoes, agriculture, or semiconductors – if they employ sophisticated methods, use advanced technology,and offer unique products and services. All industries can employ advanced technology; all industries can be knowledge intensive.The sophistication with which companies compete in a particular location, however, is strongly influenced by the quality of the local business environment.1 Companies cannot employ advanced logistical techniques, for example, without a high quality transportation infrastructure. Nor can companies effectively compete on sophisticated service without well-educated employees. Businesses cannot operate efficiently under onerous regulatory red tape or under a court system that fails to resolve disputes quickly and fairly. Some aspects of the business environment, such as the legal system, for example, or corporate tax rates, affect all industries. In advanced economies, however, the more decisive aspects of the business environment are often cluster specific; these constitute some of the most important microeconomic foundations for competition.Clusters affect competition in three broad ways:first, by increasing the productivity of companies based in the area; second, by driving the direction and pace of innovation, which underpins future productivity growth; and third, by stimulating the formation of new businesses, which expands and strengthens the cluster itself. A cluster allows each member to benefit as if it had greater scale or as if it had joined with others formally – without requiring it to sacrifice its flexibility.Clusters and Productivity. Being part of a cluster allows companies to operate more productively in sourcing inputs; accessing information, technology,and needed institutions; coordinating with related companies; and measuring and motivating improvement.Better Access to Employees and Suppliers. Companies in vibrant clusters can tap into an existing pool of specialized and experienced employees, thereby lowering their search and transaction costs in recruiting. Because a cluster signals opportunity and reduces the risk of relocation for employees, it can also be easier to attract talented people from other locations, a decisive advantage in some industries.A well-developed cluster also provides an efficient means of obtaining other important inputs.Such a cluster offers a deep and specialized supplier base. Sourcing locally instead of from distant suppliers lowers transaction costs. It minimizes the need for inventory, eliminates importing costs and delays, and –because local reputation is important –lowers the risk that suppliers will overprice or renege on commitments. Proximity improves communications and makes it easier for suppliers to provide ancillary or support services such as installation and debugging. Other things being equal, then, local outsourcing is a better solution than distantoutsourcing, especially for advanced and specialized inputs involving embedded technology, information, and service content.Formal alliances with distant suppliers can mitigate some of the disadvantages of distant outsourcing. But all formal alliances involve their own complex bargaining and governance problems and can inhibit a company’s flexibility. The close, informal relationships possible among companies in a cluster are often a superior Arrangement.In many cases, clusters are also a better alternative to vertical pared with in-house units, outside specialists are often more cost effective and responsive, not only in component production but also in services such as training. Although extensive vertical integration may have once been the norm, a fast-changing environment can render vertical integration inefficient, ineffective, and inflexible.Even when some inputs are best sourced from a distance, clusters offer advantages. Suppliers trying to penetrate a large, concentrated market will price more aggressively, knowing that as they do so they can realize efficiencies in marketing and in service.Working against a cluster’s advantages in assembling resources is the possibility that competition will render them more expensive and scarce. But companies do have the alternative of outsourcing many inputs from other locations, which tends to limit potential cost penalties. More important, clusters increase not only the demand for specialized inputs but also their supply.Access to Specialized Information. Extensive market, technical, and competitive information accumulates within a cluster, and members have preferred access to it. In addition, personal relationships and community ties foster trust and facilitate the flow of information. These conditions make information more transferable.Complementarities. A host of linkages among cluster members results in a whole greater than the sum of its parts. In a typical tourism cluster, for example, the quality of a visitor’s experience depends not only on the appeal of the primary attraction but also on the quality and efficiency of complementary businesses such as hotels, restaurants, shopping outlets, and transportation facilities. Because members of the cluster are mutually dependent, good performance by one can boost the success of the others.Complementarities come in many forms. The most obvious is when products complement one another in meeting customers’ needs, as the tourism example illustrates. Another form is the coordination of activities across companies to optimize their collective productivity. In wood products, for instance, the efficiency of sawmills depends on a reliable supply of high-quality timber and the ability to put all the timber to use – in furniture (highest quality), pallets and boxes (lower quality), or wood chips (lowest quality). In the early 1990s, Portuguese sawmills suffered from poor timber quality because local landowners did not invest in timber management. Hence most timber was processed for use in pallets and boxes, a lower-value use that limited the price paid to landowners. Substantial improvement in productivity was possible, but only if several parts of the cluster changed simultaneously.Logging operations, for example, had to modify cutting and sorting procedures, while sawmills had to develop the capacity to process wood in more sophisticated ways. Coordination to develop standard wood classifications and measures was an important enabling step. Geographically dispersed companies are less likely to recognize and capture such linkages.Other complementarities arise in marketing. A cluster frequently enhances the reputation of a location in a particular field, making it more likely that buyers will turn to a vendor based there.Italy’s strong reputation for fashion and design, for example, benefits companies involved in leather goods, footwear, apparel, and accessories. Beyond reputation, cluster members often profit from a variety of joint marketing mechanisms, such as company referrals, trade fairs, trade magazines, and marketing delegations.Finally, complementarities can make buying from a cluster more attractive for customers. Visiting buyers can see many vendors in a single trip. They also may perceive their buying risk to be lower because one location provides alternative suppliers. That allows them to multisource or to switch vendors if the need arises. Hong Kong thrives as a source of fashion apparel in part for this reason.Access to Institutions and Public Goods. Investments made by government or other public institutions– such as public spending for specialized infrastructure or educational programs – can enhance a company’s productivity. The ability to recruit employees trained at local programs, for example, lowers the cost of internal training. Other quasi-public goods, such as the cluster’s information and technology pools and its reputation, arise as natural by-products of competition.It is not just governments that create public goods that enhance productivity in the private sector. Investments by companies –in training programs, infrastructure, quality centers, testing laboratories, and so on – also contribute to increased productivity. Such private investments are often made collectively because cluster participants recognize the potential for collective benefits.Better Motivation and Measurement. Local rivalry is highly motivating. Peer pressure amplifies competitive pressure within a cluster,even among noncompeting or indirectly competing companies. Pride and the desire to look good in the local community spur executives to attempt to outdo one another.Clusters also often make it easier to measure and compare performances because local rivals share general circumstances – for example, labor costs and local market access – and they perform similar activities. Companies within clusters typically have intimate knowledge of their suppliers’ costs. Managers are able to compare costs and employees’performance with other local companies. Additionally, financial institutions can accumulate knowledge about the cluster that can be used to monitor performance.Clusters and Innovation. In addition to enhancing productivity, clusters play a vital role in a company’s ongoing ability to innovate. Some of the same characteristics that enhance current productivity have an even more dramatic effect on innovation and productivity growth.Because sophisticated buyers are often part of a cluster, companies inside clusters usually have a better window on the market than isolated competitors do. Computer companies based in Silicon Valley and Austin, Texas, for example, plug into customer needs and trends with a speed difficult to match by companies located elsewhere. The ongoing relationships with other entities within the cluster also help companies to learn early about evolving technology, component and machinery availability, service and marketing concepts, and so on. Such learning is facilitated by the ease of making site visits and frequent face-to-face contact.Clusters do more than make opportunities for innovation more visible. They also provide the capacity and the flexibility to act rapidly. A company within a cluster often can source what it needs to implement innovations more quickly. Local suppliers and partners can and do get closely involved in the innovation process, thus ensuring a better match with customers’ requirements.Companies within a cluster can experiment at lower cost and can delay large commitments until they are more assured that a given innovation will pan out. In contrast, a company relying ondistant suppliers faces greater challenges in every activity it coordinates with other organizations –in contracting, for example, or securing delivery or obtaining associated technical and service support. Innovation can be even harder in vertically integrated companies, especially in those that face difficult trade-offs if the innovation erodes the value of in-house assets or if current products or processes must be maintained while new ones are developed.Reinforcing the other advantages for innovation is the sheer pressure – competitive pressure, peer pressure, constant comparison – that occurs in a cluster. Executives vie with one another to set their companies apart. For all these reasons, clusters can remain centers of innovation for decades.Clusters and New Business Formation.It is not surprising, then, that many new companies grow up within an existing cluster rather than at isolated locations. New suppliers, for example, proliferate within a cluster because a concentrated customer base lowers their risks and makes it easier for them to spot market opportunities. Moreover, because developed clusters comprise related industries that normally draw on common or very similar inputs, suppliers enjoy expanded opportunities.Clusters are conducive to new business formation for a variety of reasons. Individuals working within a cluster can more easily perceive gaps in products or services around which they can build businesses. Beyond that, barriers to entry are lower than elsewhere. Needed assets, skills, inputs, and staff are often readily available at the cluster location, waiting to be assembled into a new enterprise.Local financial institutions and investors, already familiar with the cluster, may require a lower risk premium on capital. In addition, the cluster often presents a significant local market, and an entrepreneur may benefit from established relationships. All of these factors reduce the perceived risks of entry – and of exit, should the enterprise fail.The formation of new businesses within a cluster is part of a positive feedback loop. An expanded cluster amplifies all the benefits I have described – it increases the collective pool of competitive resources, which benefits a ll the cluster’s members. The net result is that companies in the cluster advance relative to rivals at other locations.英文文献中文翻译（二）来源：哈佛商业评论Vol.76第6期 1998年作者：迈克·E. 波特出版时间：1998簇群与新竞争经济学(美）迈克·E. 波特为什么簇群对竞争至关重要?现代竞争取决于生产力, 而非取决于投入或单个企业的规模。

英文资料与中文翻译IEEE 802.11 MEDIUM ACCESS CONTROLThe IEEE 802.11 MAC layer covers three functional areas：reliable data delivery, medium access control, and security. This section covers the first two topics.Reliable Data DeliveryAs with any wireless network, a wireless LAN using the IEEE 802.11 physical and MAC layers is subject to considerable unreliability. Noise, interference, and other propagation effects result in the loss of a significant number of frames. Even with error-correction codes, a number of MAC frames may not successfully be received. This situation can be dealt with by reliability mechanisms at a higher layer. such as TCP. However, timers used for retransmission at higher layers are typically on the order of seconds. It is therefore more efficient to deal with errors at the MAC level. For this purpose, IEEE 802.11 includes a frame exchange protocol. When a station receives a data frame from another station. It returns an acknowledgment (ACK) frame to the source station. This exchange is treated as an atomic unit, not to be interrupted by a transmission from any other station. If the source does not receive an ACK within a short period of time, either because its data frame was damaged or because the returning ACK was damaged, the source retransmits the frame.Thus, the basic data transfer mechanism in IEEE802.11 involves an exchange of two frames. To further enhance reliability, a four-frame exchange may be used. In this scheme, a source first issues a request to send (RTS) frame to the destination. The destination then responds with a clear to send (CTS). After receiving the CTS, the source transmits the data frame, and the destination responds with an ACK. The RTS alerts all stations that are within reception range of the source that an exchange is under way; these stations refrain from transmission in order to avoid a collision between two frames transmitted at the same time. Similarly, the CTS alerts all stations that are within reception range of the destination that an exchange is under way. The RTS/CTS portion of the exchange is a required function of the MAC but may be disabled.Medium Access ControlThe 802.11 working group considered two types of proposals for a MAC algorithm: distributed access protocols, which, like Ethernet, distribute the decision to transmit over all the nodes using a carrier-sense mechanism; and centralized access protocols, which involve regulation of transmission by a centralized decision maker. A distributed access protocol makes sense for an ad hoc network of peer workstations (typically an IBSS) and may also be attractive in other wireless LAN configurations that consist primarily of burst traffic. A centralized access protocol is natural for configurations in which a umber of wireless stations are interconnected with each other and some sort of base station that attaches to a backbone wired LAN: it is especially useful if some of the data is time sensitive or high priority.The end result for 802.11 is a MAC algorithm called DFWMAC (distributed foundation wireless MAC) that provides a distributed access control mechanism with an optional centralized control built on top of that. Figure 14.5 illustrates the architecture. The lower sub-layer of the MAC layer is the distributed coordination function (DCF). DCF uses a contention algorithm to provide access to all traffic. Ordinary asynchronous traffic directly uses DCE. The point coordination function (PCF) is a centralized MAC algorithm used to provide contention-free service. PCF is built on top of DCF and exploits features of DCF to assure access for its users. Let us consider these two sub-layers in turn.MAClayerFigure 14.5 IEEE 802.11 Protocol ArchitectureDistributed Coordination FunctionThe DCF sub-layer makes use of a simple CSMA (carrier sense multiple access) algorithm, which functions as follows. If a station has a MAC frame to transmit, it listens to the medium. If the medium is idle, the station may transmit; otherwise the station must wait until the current transmission is complete before transmitting. The DCF does not include a collision detection function (i.e. CSMA/CD) because collision detection is not practical on a wireless network. The dynamic range of the signals on the medium is very large, so that a transmitting station cannot effectively distinguish incoming weak signals from noise and the effects of its own transmission.To ensure the smooth and fair functioning of this algorithm, DCF includes a set of delays that amounts to a priority scheme. Let us start by considering a single delay known as an inter-frame space (IFS). In fact, there are three different IFS values, but the algorithm is best explained by initially ignoring this detail. Using an IFS, the rules for CSMA access are as follows (Figure 14.6):Figure 14.6 IEEE 802.11 Medium Access Control Logic1. A station with a frame to transmit senses the medium. If the medium is idle. It waits to see if the medium remains idle for a time equal to IFS. If so , the station may transmit immediately.2. If the medium is busy (either because the station initially finds the medium busy or because the medium becomes busy during the IFS idle time), the station defers transmission and continues to monitor the medium until the current transmission is over.3. Once the current transmission is over, the station delays another IFS. If the medium remains idle for this period, then the station backs off a random amount of time and again senses the medium. If the medium is still idle, the station may transmit. During the back-off time, if the medium becomes busy, the back-off timer is halted and resumes when the medium becomes idle.4. If the transmission is unsuccessful, which is determined by the absence of an acknowledgement, then it is assumed that a collision has occurred.To ensure that back-off maintains stability, a technique known as binary exponential back-off is used. A station will attempt to transmit repeatedly in the face of repeated collisions, but after each collision, the mean value of the random delay is doubled up to some maximum value. The binary exponential back-off provides a means of handling a heavy load. Repeated failed attempts to transmit result in longer and longer back-off times, which helps to smooth out the load. Without such a back-off, the following situation could occur. Two or more stations attempt to transmit at the same time, causing a collision. These stations then immediately attempt to retransmit, causing a new collision.The preceding scheme is refined for DCF to provide priority-based access by the simple expedient of using three values for IFS:●SIFS (short IFS):The shortest IFS, used for all immediate responseactions，as explained in the following discussion●PIFS (point coordination function IFS):A mid-length IFS, used by thecentralized controller in the PCF scheme when issuing polls●DIFS (distributed coordination function IFS): The longest IFS, used as aminimum delay for asynchronous frames contending for access Figure 14.7a illustrates the use of these time values. Consider first the SIFS.Any station using SIFS to determine transmission opportunity has, in effect, the highest priority, because it will always gain access in preference to a stationwaiting an amount of time equal to PIFS or DIFS. The SIFS is used in the following circumstances：●Acknowledgment (ACK): When a station receives a frame addressed onlyto itself (not multicast or broadcast) it responds with an ACK frame after, waiting on1y for an SIFS gap. This has two desirable effects. First, because collision detection IS not used, the likelihood of collisions is greater than with CSMA/CD, and the MAC-level ACK provides for efficient collision recovery. Second, the SIFS can be used to provide efficient delivery of an LLC protocol data unit (PDU) that requires multiple MAC frames. In this case, the following scenario occurs. A station with a multi-frame LLC PDU to transmit sends out the MAC frames one at a time. Each frame is acknowledged after SIFS by the recipient. When the source receives an ACK, it immediately (after SIFS) sends the next frame in the sequence. The result is that once a station has contended for the channel, it will maintain control of the channel until it has sent all of the fragments of an LLC PDU.●Clear to Send (CTS):A station can ensure that its data frame will getthrough by first issuing a small. Request to Send (RTS) frame. The station to which this frame is addressed should immediately respond with a CTS frame if it is ready to receive. All other stations receive the RTS and defer using the medium.●Poll response: This is explained in the following discussion of PCF.longer than DIFS(a) Basic access methodasynchronous trafficdefers(b) PCF super-frame constructionFigure 14.7 IEEE 802.11 MAC TimingThe next longest IFS interval is the: PIFS. This is used by the centralized controller in issuing polls and takes precedence over normal contention traffic. However, those frames transmitted using SIFS have precedence over a PCF poll.Finally, the DIFS interval is used for all ordinary asynchronous traffic.Point C00rdination Function PCF is an alternative access method implemented on top of the DCE. The operation consists of polling by the centralized polling master (point coordinator). The point coordinator makes use of PIFS when issuing polls. Because PI FS is smaller than DIFS, the point coordinator call seize the medium and lock out all asynchronous traffic while it issues polls and receives responses.As an extreme, consider the following possible scenario. A wireless network is configured so that a number of stations with time, sensitive traffic are controlled by the point coordinator while remaining traffic contends for access using CSMA. The point coordinator could issue polls in a round—robin fashion to all stations configured for polling. When a poll is issued, the polled station may respond using SIFS. If the point coordinator receives a response, it issues another poll using PIFS. If no response is received during the expected turnaround time, the coordinator issues a poll．If the discipline of the preceding paragraph were implemented, the point coordinator would lock out all asynchronous traffic by repeatedly issuing polls. To prevent this, an interval known as the super-frame is defined. During the first part of this interval, the point coordinator issues polls in a round, robin fashion to all stations configured for polling. The point coordinator then idles for the remainder of the super-frame, allowing a contention period for asynchronous access.Figure l4.7 b illustrates the use of the super-frame. At the beginning of a super-frame, the point coordinator may optionally seize control and issues polls for a give period of time. This interval varies because of the variable frame size issued by responding stations. The remainder of the super-frame is available for contention based access. At the end of the super-frame interval, the point coordinator contends for access to the medium using PIFS. If the medium is idle. the point coordinator gains immediate access and a full super-frame period follows. However, the medium may be busy at the end of a super-frame. In this case, the point coordinator must wait until the medium is idle to gain access: this result in a foreshortened super-frame period for the next cycle.OctetsFC=frame control SC=sequence controlD/I=duration/connection ID FCS=frame check sequence（a ） MAC frameBitsDS=distribution systemMD=more data MF=more fragmentsW=wired equivalent privacy RT=retryO=orderPM=power management (b) Frame control filedFigure 14.8 IEEE 802.11 MAC Frame FormatMAC FrameFigure 14.8a shows the 802.11 frame format when no security features are used. This general format is used for all data and control frames, but not all fields are used in all contexts. The fields are as follows:● Frame Control: Indicates the type of frame and provides contr01information, as explained presently.● Duration/Connection ID: If used as a duration field, indicates the time(in-microseconds) the channel will be allocated for successful transmission of a MAC frame. In some control frames, this field contains an association, or connection, identifier.●Addresses: The number and meaning of the 48-bit address fields dependon context. The transmitter address and receiver address are the MAC addresses of stations joined to the BSS that are transmitting and receiving frames over the wireless LAN. The service set ID (SSID) identifies the wireless LAN over which a frame is transmitted. For an IBSS, the SSID isa random number generated at the time the network is formed. For awireless LAN that is part of a larger configuration the SSID identifies the BSS over which the frame is transmitted: specifically, the SSID is the MAC-level address of the AP for this BSS (Figure 14.4). Finally the source address and destination address are the MAC addresses of stations, wireless or otherwise, that are the ultimate source and destination of this frame. The source address may be identical to the transmitter address and the destination address may be identical to the receiver address.●Sequence Control: Contains a 4-bit fragment number subfield used forfragmentation and reassembly, and a l2-bit sequence number used to number frames sent between a given transmitter and receiver.●Frame Body: Contains an MSDU or a fragment of an MSDU. The MSDUis a LLC protocol data unit or MAC control information.●Frame Check Sequence: A 32-bit cyclic redundancy check. The framecontrol filed, shown in Figure 14.8b, consists of the following fields.●Protocol Version: 802.11 version, current version 0.●Type: Identifies the frame as control, management, or data.●Subtype: Further identifies the function of frame. Table 14.4 defines thevalid combinations of type and subtype.●To DS: The MAC coordination sets this bit to 1 in a frame destined to thedistribution system.●From DS: The MAC coordination sets this bit to 1 in a frame leaving thedistribution system.●More Fragments: Set to 1 if more fragments follow this one.●Retry: Set to 1 if this is a retransmission of a previous frame.●Power Management: Set to]if the transmitting station is in a sleep mode.●More Data: Indicates that a station has additional data to send. Each blockof data may be sent as one frame or a group of fragments in multiple frames.●WEP：Set to 1 if the optional wired equivalent protocol is implemented.WEP is used in the exchange of encryption keys for secure data exchange.This bit also is set if the newer WPA security mechanism is employed, as described in Section 14.6.●Order：Set to 1 in any data frame sent using the Strictly Ordered service,which tells the receiving station that frames must be processed in order. We now look at the various MAC frame types.Control Frames Control frames assist in the reliable delivery of data frames. There are six control frame subtypes:●Power Save-Poll (PS-Poll): This frame is sent by any station to the stationthat includes the AP (access point). Its purpose is to request that the AP transmit a frame that has been buffered for this station while the station was in power saving mode.●Request to Send (RTS):This is the first frame in the four-way frameexchange discussed under the subsection on reliable data delivery at the beginning of Section 14.3.The station sending this message is alerting a potential destination, and all other stations within reception range, that it intends to send a data frame to that destination.●Clear to Send (CTS): This is the second frame in the four-way exchange.It is sent by the destination station to the source station to grant permission to send a data frame.●Acknowledgment:Provides an acknowledgment from the destination tothe source that the immediately preceding data, management, or PS-Poll frame was received correctly.●Contention-Free (CF)-End: Announces the end of a contention-freeperiod that is part of the point coordination function.●CF-End+CF-Ack:Acknowledges the CF-End. This frame ends thecontention-free period and releases stations from the restrictions associated with that period.Data Frames There are eight data frame subtypes, organized into two groups. The first four subtypes define frames that carry upper-level data from the source station to the destination station. The four data-carrying frames are as follows: ●Data: This is the simplest data frame. It may be used in both a contentionperiod and a contention-free period.●Data+CF-Ack: May only be sent during a contention-free period. Inaddition to carrying data, this frame acknowledges previously received data.●Data+CF-Poll: Used by a point coordinator to deliver data to a mobilestation and also to request that the mobile station send a data frame that it may have buffered.●Data+CF-Ack+CF-Poll: Combines the functions of the Data+CF-Ack andData+CF-Poll into a single frame.The remaining four subtypes of data frames do not in fact carry any user data. The Null Function data frame carries no data, polls, or acknowledgments. It is used only to carry the power management bit in the frame control field to the AP, to indicate that the station is changing to a low-power operating state. The remaining three frames (CF-Ack, CF-Poll,CF-Ack+CF-Poll) have the same functionality as the corresponding data frame subtypes in the preceding list (Data+CF-Ack, Data+CF-Poll, Data+CF-Ack+CF-Poll) but withotit the data. Management FramesManagement frames are used to manage communications between stations and APs. The following subtypes are included:●Association Request：Sent by a station to an AP to request an association,with this BSS. This frame includes capability information, such as whether encryption is to be used and whether this station is pollable.●Association Response:Returned by the AP to the station to indicatewhether it is accepting this association request.●Reassociation Request: Sent by a station when it moves from one BSS toanother and needs to make an association with tire AP in the new BSS. The station uses reassociation rather than simply association so that the new AP knows to negotiate with the old AP for the forwarding of data frames.●Reassociation Response:Returned by the AP to the station to indicatewhether it is accepting this reassociation request.●Probe Request: Used by a station to obtain information from anotherstation or AP. This frame is used to locate an IEEE 802.11 BSS.●Probe Response: Response to a probe request.●Beacon: Transmitted periodically to allow mobile stations to locate andidentify a BSS.●Announcement Traffic Indication Message: Sent by a mobile station toalert other mobile stations that may have been in low power mode that this station has frames buffered and waiting to be delivered to the station addressed in this frame.●Dissociation: Used by a station to terminate an association.●Authentication：Multiple authentication frames are used in an exchange toauthenticate one station to another.●Deauthentication:Sent by a station to another station or AP to indicatethat it is terminating secure communications.IEEE802.11 媒体接入控制IEEE 802．11 MAC层覆盖了三个功能区：可靠的数据传送、接入控制以及安全。

英文资料翻译原文

英文资料翻译原文Boiler management:General management principles and operating procedures are well known and must be always followed to avoid boiler mishap.With many small package boiler,the automatic control sequence usually ensures that the boiler fire is initially ignited from a diesel oil supply,and changed over to the usual source when ignition is completed.With good management ,to facilitate subsequent starting from cold,the fuel system of large boilers will have been flushed through with diesel oil when the boiler was on light duty immediately prior to being secured.When burning such diesel fuel it is essential for safety that only the correct(small) burner tip should be used.It should be kept in mind that if fire does not light,immediately shut off fuel and vent furance.Complete ignition of fuel in the furance is essential.The burner flame,the smoke indicator and the funnel should be frequently observed.With satisfactory combustion,the flame should appear incandescent with an orange shade at the flame tip,and a faint brownish haze should show at the funnel.If on fist ignition the flame is uncertain,badly shaped and separates from the primary swirler ,momentary opening or closing of air register may correct.The PH value of the boiler feed water should kept between 8 and 9 and the boiler density less than 300 ppm but,if water samples show a heavy concentration of suspended mater,short blow-downs of 20 seconds duration should be given until the sludge content is seen to be reduced.The boiler should be blown down when the oil burner is operating,the water level lowered and then restored to prove the functioning of the low water cut-out and the oil burner start-up equipment.the boiler scum valve should also be operated at this time to keep the water level clear floating scum.Fuel burner components and igniter electrodes should be cleaned weekly and the furance examined to ensure that there are no excess carbon deposits.Tubes in the exhaust gas section of the boiler should be brushed through at about six-monthly intervals,and those in the oil-burning section periodically examined and cleaned as necessary with a wire bristle brush.With correct feed water treatment,blow-down procedures and sludge contents in water samples at a stable level,it should not be necessary to wash out the water side of the boiler more than once every three or four months.Boiler fires may be out of for long periods when a ship is at sea and the boiler steaming maintained by heat input from waste heat recovery plant.This operation is free from hazard,but feed water and boiler water treatment must be maintained to prevent internal deterioration or scale formation.Water level controller must be kept operable to protect external steam-using plant from water “carry-over”danger.If a boiler is isolated from the steam-using system it must be kept either in closed dry storage with a suitable internal desiccant,or completely full of treated water,or under a low steam pressure preferably maintained by a steam-heated coil.Regular testing of boiler protective devices must be implemented.Frequent comparison of drum-mounted and remote reading water levelindicators:discrepancies between these have contributed to failures because of overheating through shortage of water,when a boiler was being oil-fired.If in doubt as to the true boiler water level,i.e.whether a water level indicator sightglass is completely full or empty,when a unit is being oil-fired the fire should be immediately extinguished until the true level is resolved.Procedures should be predetermined and followed in the event of shortage of water,bulging or fracture of plates or furance,or bursting of water tubes .In general,fires should be immediately extinguished by remote tripping of fuel supply valves;forced draught air pressure maintained if there is any risk of escaping steam entering the boiler room;stem pressure relieved if metallic fractures seem possible;and boiler water level maintained,where practicable,until the boiler begins to cool down. Regular operation of soot blowers,if there are fitted,when the boiler is on oil-fired operation.The steam supply line must be thoroughly warmed and drained before blowers are used,the air/fuel ratio increased throughout the action,and the blowers greased after use.Immediate investigation of any high salinity alarms in condensate system,and elimination of any salt water or oil contamination of boiler feed water system. Safety precautions taken before entering a boiler connected to another boiler under steam.Engine governor:A governor maintains the engine speed at the desired value no matter how much load is applied.It achieves this by adjustment of the fuel pump racks.Any change in load will produce a change in engine speed,which will cause the governor to initiate a fuel change.The governor is said to be speed sensing as a speed change has to take place before the governor can react to adjust the fuel setting.The sample mechanical governor employs rotating weights which move outward as the speed increases and inward as the speed reduces.This movement,acting through a system of linkages,can be used to regulate the fuel rack.Rather than having the rotating weights directly move the fuel linkage,hydraulic governor employ a servo system so the rotating weights only need to move a pilot valve in the hydraulic line.This makes the governor more ernors of this type require a speed change to tale place in order that they may initiate fuel rack adjustment.This is known as speed drop and this is a definite speed for each load therefore the governor can not control to a single speed.A modification to the governor hydraulic system introduces a facility known as compensation which allows for further fuel adjustment after the main adjustment has taken place due to speed pensation restores the speed to its original desired value so the engine can operate at the same speed under all loads.Such a governor is said to be isochronous as the engine operates at a single speed.However,the governor is still speed sensing,so it is not ideal for all applications.Speed sensing governor:Where the engine drives an alternator any speed change results in a change in supply frequency.;Large changes in electrical supply frequency can have an adverse effect on sensitive electronic equipment connected to that supply.Where electrical generation is involved it is possible to monitor taking rotational speed as the control signal.Such governors are know as load sensing.It isextremely difficult to make a mechanical governor load sensing,even with a hydraulic system,but an electronic governor can take account of the electrical load applied to the engine and so can be considered “speed sensing”.Electronic governor:Electronic governors essentially comprise two parts,the digital control unit and the hydraulic actuator,which are interlinked but it is useful to consider them separately.Electronic governor controller: The digital control may be considered as a “black box” in which signals are processed to produce a control signal which is sent to the actuator.The controller may be programmed in order to sent points and parameters.The controller is a sensitive piece of electronic equipment and should not be mounted on the engine or in areas where it will be exposed to vibration,humidity or high temperatures.It should be ventilated in order to keep it cool and should be shielded from high-voltage or high-current devices which will cause electromagnetic interference.Similar restriction apply to the location of signal cables.Speed signals are taken from two speed transducers,one on each side of the flexible coupling which attaches the engine to the load.Failure of one transducer produces a minor alarm but allows continued operation with an electronic over speed value may be programmed into the controller in which case detection of over speed will cause the engine to be shut off.If the load is provided by an electrical machine the output from that machine provides a signal for load sharing.Should this transducer fail the load on the engine will be determined by the position of the governor actuator output.The controller can also receive signals from other transducers including in the engine’s air inlet pressure,which allows the fuel to be limited when starting.After processing input signals in accordance with programmed requirements an output signal will be sent to the governor actuator.Electronic governor actuator:The actuator is a hydraulic device which moves the fuel linkage in response to a signal from the digital controller.The operating mechanism is contained with an oil filled casing.Oil pressure is provided by a servomotor pump driven by a shaft connected to the engine camshaft.At the heart of the actuator is the torque motor beam is banlanced where the engine is operating at the desired speed.a.Consider a load increaseThe controller increases current to the torque motor which,in turn,causes the centre adjust end of the torque motor beam to be lowered.Oil flow through the nozzle is reduced ,which increases pressure on the top of the pilot valve plunger.This moves downward,unconering the port which allows pressure oil to the lower face of the power piston,which in turn moves upward, rotating the terminal shaft thereby increasing the fuel to the engine.As the terminal shaft rotates the torque motor beam is pulled upwards by increased tension in the feedback spring,increasing the clearance between the centers adjust and the nozzle.Leakage past the nozzle increases,reducing the pressure on the upper face of the pilot valve plunger and allowing the pilot valve to move upwards.This cuts off further oil to the power piston,and movement of the fuel control linkage ceases.Balance is restored to the torque motor beam with downward force from the feedback spring being matched by upwards force from oilleakage from the nozzle.The engine then operates at an increased fuel setting which matches the new load requirement at the set speed.B.consider a load reductionA decrease in load produces a reduction in current acting on the torque motor,which tends to turn the beam in an anti-clockwise direction about the torque motor pivot,resulting in an increased clearance between the centre adjust and the nozzle.Pressure reduces on the upper face of the pilot valve plunger and the pilot valve moves upwards,allowing the lower face of the power piston to connect with the geromotor pump suction.the power piston moves downwards ,rotating the terminal shaft which reduces fuel to the engine and tension in the feedback spring.The center adjust end of the torque motor beam is forced down,thereby reducing clearance between the centre adjust and the nozzle.Leakage past the nozzle reduces pressure on the upper face of the pilot valve increases and the pilot valve moves upwards,shuting off the connection between the lower face of the power piston and pump suction .The engine now operates with reduced load and reduced fuel,but at the same original speed.。

SYSMAC CJ SeriesCJ1G/H-CPU□□H,CJ1M-CPU□□,CJ1G-CPUProgrammable ControllersOperation ManualRevised July 2002Application PrecautionsObserve the following precaution when using the PLC System.●You must use the CX-Programmer (programming software that runs on Windows)ifyou need to program more than one task. A Programming Console can be used to program only one cyclic task plus interrupt tasks.A Programming Console can, however, be used to edit multitask programs originally created with the CX-Programmer.！Warning Always heed these precautions, Failure to abide by the following △precautions could lead to serious or possibly fatal injury.●Always connect to a ground of 100Ωor less when installing the Units. Notconnecting to a ground of 100Ωor less may result in electric shock.●A ground of 100Ωor less must be installed when shorting the GR and LGterminals on the Power Unit.●Always turn OFF the power supply to the PLC before attempting any of thefollowing .Not turning OFF the power supply may result in malfunction or electric shock..●Mounting or dismounting Power Supply Units, CPU Units, or any other Units.●Assembling the Units.●Setting DIP switches or rotary witches.●Connecting cables or wiring the system.●Connecting or disconnecting the connectors.！Caution Failure to abide by the following precautions could lead to faulty operation △of the PLC or the system, or could damage the PLC or PLC Units. Always heed these precautions.●A CJ-series CPU Unit is shipped with the battery installed and the time alreadyset on the internal clock. It is not necessary to clear memory or set the clock before application, as it is for the CS-series CPU Units.●The user program and parameter area data in CJ1-H CPU Units is backed up in the CPU Unit when the backup operation is in progress. Do not turn OFF the power supply to the CPU Unit when the BKUP indicator is lit .The data will not be backed up if power is turned OFF.●If ,when using a CJ1H-CPU Unit ,the PLC Setup is set to specify using the mode set on the Programming Console and a Programming Console is not connected ,the CPU Unit will start in RUN mode .This is the default setting in the PLC Setup. ( A CS1 CPU Unit will start in PROGRAM mode under the same conditions .)●When creating an AUTOEXEC.IOM file from a Programming Device (a Programming Console or the CX-Programmer)to automatically transfer data at startup, set the first write address to D20000 and be sure that the size of data written does not exceed the size of the DM Area. When the data file is read from the Memory Card at startup, data will be written in the CPU Unit starting at D20000 even if another address was set when the AUTOEXEC.IOM file was created .Also, if the DM Area is exceeded(which is possible when the CX-Programmer is used),the remaining data will be written to the EM Area.●Always turn ON power to the PLC before turning ON power to the control system. If the PLC power supply is turned ON after the control power supply, temporary errors may result in control system signals because the output terminals on DC Output Units and other Units will momentarily turn ON when power is turned ON to the PLC.●Fail-safe measures must be taken by the customer to ensure safety in the event that outputs from Output Units remain ON as a result of internal circuit failures, which can occur in relays , transistors, and other elements.●Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect , missing, or abnormal signals caused by broken signal lines, momentary power interruption, or other causes.●Interlock circuits, limit circuits, and similar safety measures in external circuits(i.e, not in the Programmable Controller)must be provided by the customer.●Do not turn OFF the power supply to the PLC when data is being transferred. Inparticular, do not turn OFF the power supply when reading or writing a Memory Card. Also, do not remove the Memory Card when the BUSY indicator is lit .To remove a Memory Card, first press the memory card power supply switch and then wait for the BUSY indicator to go out before removing the Memory Card.●If the I/O Hold Bit is turned ON, the output from the PLC will not be turnedOFF and will maintain their previous status when the PLC is switched from RUN or MONITOR mode to PROGRAM mode .Make sure that the external loads will not produce dangerous conditions when this occurs.(When operation stops for a fatal error ,including those produced with the FALS(007)instruction, all outputs from Output Unit will be turned OFF and onlu the internal output status will be maintained.)●The contents of the DM, EM and HR Areas in the CPU Unit are backed up bu aBattery.If the Battery voltage drops, this data may be lost. Provide countermeasures in the program using the Battery Error Flag (A40204) to re-initialize data or take other actions if the Battery voltage drops.SYSMAC CJ 系列CJ1G/H-CPU□□H,CJ1G-CPU□□可编程序控制器操作手册2002年7月修订应用注意事项使用PC系统时要遵循下列各注意事项。
