The Intelligent Building

One of the benefits of the rapid evolution of information technology has been the development of systems that can measure, evaluate, and respond to change。An enhanced ability to control change has sparked developments in the way we design our physical environment, in particular, the buildings in which we work。As a result, we are witnessing significant growth in the area of "Intelligent Buildings"--buildings that incorporate information technology and communication systems, making them more comfortable, secure, productive, and cost-effective

What is an Intelligent Building?

An Intelligent Building is one equipped with the telecommunications infrastructure that enables it to continuously respond and adapt to changing conditions, allowing for a more efficient use of resources and increasing the comfort and security of its occupants。An Intelligent Building provides these benefits through automated control systems such as: heating, ventilation, and

air-conditioning (HVAC);fire safety;security;and energy/lighting management。For example, in the case of a fire, the fire alarm communicates with the security system to unlock the doors。The security system communicates with the HVAC system to regulate the flow of air to prevent the fire from spreading。

What benefits do Intelligent Buildings offer their owners and occupants?

The introduction in the workplace of computers printers photocopiers, and fax machines has increased indoor pollution。Electrical and telecommunications facilities in office buildings are under pressure to satisfy the demands created by the rapid growth of computer and networking technologies。These factors have a definite impact on productivity. New technology can be used to create Intelligent Buildings that address these problems by providing a healthier, more productive, and less energy-intensive work environment。As these are critical factors for business

success, owners of Intelligent Buildings have a clear advantage in attracting and retaining

21st-century tenants。

How do Intelligent Buildings lead to cost savings?

The Intelligent Building concept recognizes that the true cost of a building is not simply its cost of construction; it must contain the costs of operate and maintenance over the structure's life span。By optimizating automated control, communication, and management systems, Intelligent Buildings cost has reduced in all of these areas。They also guard against the increasing of repairing costs, productivity loss, revenue loss, and the loss of customers。

Can an Intelligent Building infrastructure be installed in existing buildings? Yes。The key competency of transformating conventional buildings into intelligent ones is installing single structured cabling network。Standard buildings featured in using different kinds of designs and administration methods from system to system。The additional facility of construction structured turns a conventional building into an intelligent one which can provide with increased efficiency and guarding it against system breakdowns。

Why do Intelligent Buildings increasingly become a part of business imperative?

Because they contribute to the business requirements as follows:

· To communicate data quickly and reliably

· To exercise greater control over the work environment

· To improve productivity and cost-effectiveness

In response to these needs, it offers its Business Solution of intelligent wiring。

Intelligent buildings design and construction management systems

The field of Intelligent Buildings, Intelligent Homes, Building Management Systems (BMS) encompass an enormous variety of technologies, across commercial, industrial, institutional and

domestic buildings which including energy management systems and building controls。The function of Building Management Systems is central to 'Intelligent Buildings' concepts;its purpose is to monitor the function of building such as lighting,heating,security, CCTV and alarm systems;access control;audio-visual and entertainment systems ventilation filtration and climate control etc even time & attendance control and reporting (notably staff movement and availability)。The potential within these concepts and the surrounding technology is vast and our live are changing from the effects of Intelligent Buildings developments on our living and working environments。

The origins of Intelligent Buildings and Building Management Systems have roots in the industrial sector in the 1970's, from the systems and controls used to automate production processes and to optimise plant performances。The concepts and applications were then adapted, developed and modularised during the 1980's。

Intelligent buildings - control system

The essence of Building Management Systems lies in the Intelligent Buildings and control technologies, which allows integration, automation, optimising services and equipment provide services and managing environment。The essence of Intelligent Management Systems lies in Programmable Logic Controllers (PLC) which formed the original basis of the control technologies。Later the developments of commercial and residential applications were based on “distributed-intelligence microprocessors”. Taking advantage of these technologies allows to use various Internet construction and services, which often significantly reduces cost and saves energy。

Heating - time-based control

· Temperature control: when external temperature reaches a set level (0°C),run heating system pumps to protect the system from freezing or frost.

· Compensated systems: It will heat temperature to control the electricity when the temperature drops and this will give a rise in the circuit flow temperature.

· Thermostatic radiator valves: the thermodetector of which installing in the same room can change the radiator radiates accordingly to the relevant flow.

· Proportional control: including auto-switching equipment and auto-output adjusting. Lighting control methods

· Zones: In order to avoid only a small parts of lights can be used in a large area, lights are switched on corresponding to the use and layout of the lit areas.

· Time control: to switch on and off automatically in each zone at times to a preset schedule for light use。

· Passive Infra-Red (PIR) Occupancy sensing: In areas which are occupied intermittently, occupancy sensors can be used to indicate whether or not anybody is present and control the switch of lights accordingly。

Building management systems and intelligent buildings - energy savings

Until recent years, energy efficiency has been used at a relatively low priority and building owners and investors pay little attention to it。However, with the dramatic increase of energy use and decrease of energy capacity, the concept of energy cost-efficiency has already soon became the important strategy of estate management, facilities management and also has being involving into the construction.

For lighting, energy savings can be up to 75% of the original circuit load, which represents 5% of the total energy consumption of the residential and commercial sectors。

Experiences from studies in Austria suggest potential heating and cooling energy savings are up to 30% in public buildings。Even allowing for the fact that buildings used in the study may have been those with particularly high energy usage, the figure is an impressive one

Building management systems and intelligent buildings - environmental and greenhouse gas benefits

Greenhouse gas emission reductions depend on and correlate to reductions in energy use。Intelligent Buildings and Building Management Systems technologies contribute directly to the reduction in energy use, in commercial, industrial, institutional and domestic residential sectors。In short, Intelligent Buildings and suitably applied Building Management Systems are good for the environment。

Legislation and environmental standards;health and safety regulations;and global trends towards improving indoor air quality standards are all significant drivers of - and provide a continuous endorsement of the need for - Building Management Systems and the Intelligent Buildings technologies。

Government Initiatives around the world are also driving the development and adoption of Building Management Systems technologies。For example the UK Carbon Trust allows Enhanced Capital Allowance (ECA) to be offset against taxation on energy efficient systems, which enables savings of around 30% for all energy-related Building Management Systems and Intelligent Buildings equipment, and the associated installation and design costs。

Building management systems and intelligent buildings - market trends

In Britain, through the establishment and control of the main high-tech fully into the new decoration industry, in recent years, the British buildings market to set up the new management system, make significant changes innovation.

· Heating system 70%。

· Hot water control system 90%。

· Air conditioning control system 80%。

But according to the European commission statistics, as many as 90% of existing buildings have

not adapt or invalid control system, many need a thorough overhaul.

The "intelligence" construction has become a real estate developers and owners hot spot, 24 hour visible entrance guard, long-distance meter reading billing, all kinds of community service projects and convenient video on demand, on the web for village residents offered many life convenient. But the "intelligence" construction is a complex technology application project, as a community "intelligent" of the implementation of the relevant departments, need to pay attention, be ware of new construction erroneous zone.

1、Beware of haste to build, lack of careful planning.。"Intelligent" general by broadband network and several related the sub-project to realist, long-distance meter reading billing, security monitoring, all kinds of alarm systems, Internet browsing, etc are to be included in the operation of the residential broadband network category. In software, needs to have the special application scheme for the development of community network information management system. The author thinks that although all sorts of relevant products have been listed, individual products have already become more and more mature, but quite part of products in the technical specifications of the lack of uniform standard, integrated broadband and intelligence of conditions remain to be mature. Many residents of the village persuaded by manufacturers install visible interphone today, assemble with long-distance meter reading tomorrow , this phenomenon do not only cause with various circuitry within the cross, repeat construction, and independent running each manufacturer equipment to realize "intelligent" original intention in the building area of . Certainly, this is not to say that the current implementation can't intelligent, but the broadband network lying, LAN and the equipment can be brought into operation should be of broadband in under the guidance of experts.

2、Beware of "broadband" business trap. As "broadband" gradually popular, a group of specialized business "broadband" business company arises at the historic moment. They

frequently to property district promised to put into tens of thousands of funds; the plot offers one or two houses and other intelligent construction undertaken by "broadband" business company. The author thinks that "broadband" commercial service as a market behavior, both parties shall in contract introduced in detail in the profits to investors, Property Company also should clearly understand both sides in the future cooperation in their respective rights and obligations. In the process of real estate, a community in the future the owners of the consumption of whether they should have the "right to know" and "options", how the legitimacy of the contract is worth discussing.

3、Beware of pay heavily close attention to hardware, software, lightly weight, the tendency of investment use. In the implementation of intelligent management solutions in the process, some units invest a lot of money to buy equipment, professional maintenance personnel allocation, and software is to disdain to investment, the use of the software is also the secretary or other personnel part-time settles., however, in the implementation of the process of intelligent software is the foundation and the core, a set of complete information management plan, no matter how perfect hardware facilities, lack of software support (exactly say support) the system is not a successful design.

The author thinks that in the process of implementation of "intelligence" , prior to listen to all levels of management department opinions, the "intelligence" to realize what management function, this is the core of make plan; And then listen to the opinions of the professional staff, give full play to the function of equipment in hardware, on the basis of pay attention to in the management means, existing equipment, the scheme can provide for management which data, what are the specific management work to supplement and improve. The goal is to clear, avoid by all means is to "leadership will" and "take it for granted" to do.

智能建筑设计与建筑管理系统

智能建筑领域,智能化住宅,建筑管理系统(房舍)包含了多种技术, 经由全国商业、工业及住宅楼宇的机构,包括能源管理制度,建立管制。建筑管理系统的功能是智能型建筑概念的核心;其目的是为了监控建筑物的功能,例如:灯光、供暖、安全、闭路电视和警报系统;视听娱乐系统、通风、过滤和气候控制等准确控制;甚至于时间控制。这些潜在的观念及多种边缘技术,正在改变我们的生活。

智能建筑的起源与建设管理体制在20世纪70年代根植于工业部门从系统和控制化用于自动化生产过程和优化工厂效益。上世纪80年代,当时的概念与应用相结合协调发展。

智能楼宇控制论

建筑管理系统的本质是在智能建筑和控制技术,它使一体化、自动化、所有优化服务和设备提供服务和管理环境。智能化管理系统本质是建立在可编程控制器(PLC)原有基础上形成的控制技术。后来在商业和住宅的应用发展是基于“分布式智能微处理器”。利用这些技术可以充份运用到各种网站建设和服务,往往大幅降低成本,大量节省能源。

供暖时间的控制

●温度控制:当外部温度达到设置温度(0℃)的时候运行加热泵防止系统冷冻或者结冰。

●补偿制度: 当温度下降时,它将通过加热温度控制电路,使气温上升。

●温控阀: 安装在同一房间的温度检测器通过相应的流量控制器改变散热器散热。

●比例控制:包括自动开关设备自动调节输出。

照明控制方法

●分区控制: 为了避免出现大面积灯具而只有一小部分需要使用的情况的发生,不同区域的灯具都有相应的开关。

●时间控制:自动转换,间断地在每一个区域根据预定日程使用。

●红外传感器的使用:在所监管的地区,使用感应器可以用来判断是否有人在场控制灯具的开关。

建筑管理系统和智能建筑的能源节约

近年来,能源利用率一直比较低,业主和投资者的对此也不重视。然而,随着能源使用急剧增加和能源储备量急剧减少,能源效益观念已迅速成为房地产管理、设备管理和业务的重要战略,并且正在渗入建筑行业。

在照明方面,住宅和商业部门按投资总量5%节省能源可达原电路负荷75%。

经验表明奥地利公共建筑物节能能力高达30%,就算考虑到建筑物的使用与研究,尤其是那些可能使用的大量能源,这个数字是令人印象深刻的。

和建筑管理系统和智能建筑环境效益有关的智能建筑技术、建筑管理系统在工商业和住宅业减少温室气体的排放、降低能源使用直接有助于减少能源使用。总之, 良好的智能建筑的建设和管理体制对环境有利。

立法和环保标准,健康与安全法规,全球趋势和改善室内空气品质标准均显示需要建设智能化建筑管理系统和技术。政府还倡议全世界通过技术开发建设管理系统。譬如英国信托允许所有与能源有关的建筑管理系统、智能楼宇设备、设计与安装及相关费用抵消30%左右的税收。

建筑管理系统和智能建筑市场趋势

在英国,通过建立和控制主要的高新技术全面推向新装修行业,近些年来,英国建筑市场建立新的管理体制,促成重大革新。所有部门建议:

●加热系统70%。

●热水控制系统90%。

●空调控制80%。

不过据欧洲委员会统计,多达90%的现有建筑物有不适应的或无效的控制系统,许多需要彻底翻修。

小区的“智能化”建设已经成为房地产开发商和业主关注的热点,24小时可视门禁、远程抄表计费、各种社区服务项目以及方便的视频点播、网上浏览为小区居民提供了诸多生活上的方便。但小区的“智能化”建设是一项技术复杂的应用项目,作为小区实施“智能化”的有关部门,需要多加注意,谨防步入新的建设误区。

一、谨防仓促上马,缺乏周密规划。“智能化”一般由宽带网和若干相关子项目来实现,远程抄表计费、保安监控、各种报警系统、因特网浏览等均需纳入小区宽带网的运行

范畴。在软件方面,更需要有专门针对小区应用方案开发的网络信息管理系统。笔者认为尽管各种相关的产品已纷纷上市,个别产品已趋于成熟,但相当一部分产品在技术规范方面还缺乏统一的标准,集成宽带、智能化的条件还有待成熟。许多居民小区在厂家的说服下今天装可视对讲、明天装远程抄表,这样做不但造成小区建筑物内各种线路错综交叉、重复施工,而且独立运行的各厂家设备无法实现“智能化”的初衷。当然这不是说目前就不能实施智能化,不过小区的宽带网敷设、局域网和可纳入宽带运行的各种设备应在专家的指导下进行。

二、谨防“宽带”商业陷阱。随着“宽带”逐步升温,一批专门经营“宽带”业务的公司应运而生。他们动辄向物业小区许诺投入数以万计的资金,小区除提供一二间住房外,其他的智能化建设便由他们承包。笔者认为“宽带”的商业化服务作为一种市场化行为,双方应在合同中详尽地介绍投资方日后可获得的收益,物业公司也应该清楚地了解双方在未来合作中各自的权利和义务。在物业管理过程中,小区的业主们在这种未来的消费中是否应当有“知情权”和“选择权”,合同的合法性如何都是值得商榷的。

三、谨防重硬件、轻软件、重投资、轻使用的倾向。在实施智能化管理方案过程中,一些单位投入大量资金购买设备,配置专业养护人员,而对软件却不屑于投资,软件的使用也是秘书或其他人员兼职了事。殊不知,在实施智能化的过程中软件是基础和核心,一套完整的信息化管理方案,无论硬件设施多么完美,缺乏软件的支持(确切说是支撑)其系统也不是一个成功的设计。

笔者认为,在实施“智能化”的过程中,事先要听取各级管理部门的意见,研究“智能化”要实现什么管理职能,这是制定方案的核心;其次要多听听专业人员的意见,在充分发挥硬件设备功能的基础上,注重在管理手段上,现有设备、方案能够对管理工作提供哪些数据,对具体管理工作有哪些补充和提高。目的要明确,切忌以“领导意志”和“想

当然”办事。

外文出处: 《Exploiting Software How to Break Code》By Greg Hoglund, Gary McGraw Publisher : Addison Wesley Pub Date : February 17, 2004 ISBN : 0-201-78695-8 译文标题: JDBC接口技术 译文: JDBC是一种可用于执行SQL语句的JavaAPI(ApplicationProgrammingInterface应用程序设计接口)。它由一些Java语言编写的类和界面组成。JDBC为数据库应用开发人员、数据库前台工具开发人员提供了一种标准的应用程序设计接口,使开发人员可以用纯Java语言编写完整的数据库应用程序。 一、ODBC到JDBC的发展历程 说到JDBC,很容易让人联想到另一个十分熟悉的字眼“ODBC”。它们之间有没有联系呢?如果有,那么它们之间又是怎样的关系呢? ODBC是OpenDatabaseConnectivity的英文简写。它是一种用来在相关或不相关的数据库管理系统(DBMS)中存取数据的,用C语言实现的,标准应用程序数据接口。通过ODBCAPI,应用程序可以存取保存在多种不同数据库管理系统(DBMS)中的数据,而不论每个DBMS使用了何种数据存储格式和编程接口。 1.ODBC的结构模型 ODBC的结构包括四个主要部分:应用程序接口、驱动器管理器、数据库驱动器和数据源。应用程序接口:屏蔽不同的ODBC数据库驱动器之间函数调用的差别,为用户提供统一的SQL编程接口。 驱动器管理器:为应用程序装载数据库驱动器。 数据库驱动器:实现ODBC的函数调用,提供对特定数据源的SQL请求。如果需要,数据库驱动器将修改应用程序的请求,使得请求符合相关的DBMS所支持的文法。 数据源:由用户想要存取的数据以及与它相关的操作系统、DBMS和用于访问DBMS的网络平台组成。 虽然ODBC驱动器管理器的主要目的是加载数据库驱动器,以便ODBC函数调用,但是数据库驱动器本身也执行ODBC函数调用,并与数据库相互配合。因此当应用系统发出调用与数据源进行连接时,数据库驱动器能管理通信协议。当建立起与数据源的连接时,数据库驱动器便能处理应用系统向DBMS发出的请求,对分析或发自数据源的设计进行必要的翻译,并将结果返回给应用系统。 2.JDBC的诞生 自从Java语言于1995年5月正式公布以来,Java风靡全球。出现大量的用java语言编写的程序,其中也包括数据库应用程序。由于没有一个Java语言的API,编程人员不得不在Java程序中加入C语言的ODBC函数调用。这就使很多Java的优秀特性无法充分发挥,比如平台无关性、面向对象特性等。随着越来越多的编程人员对Java语言的日益喜爱,越来越多的公司在Java程序开发上投入的精力日益增加,对java语言接口的访问数据库的API 的要求越来越强烈。也由于ODBC的有其不足之处,比如它并不容易使用,没有面向对象的特性等等,SUN公司决定开发一Java语言为接口的数据库应用程序开发接口。在JDK1.x 版本中,JDBC只是一个可选部件,到了JDK1.1公布时,SQL类包(也就是JDBCAPI)

Inventory management Inventory Control On the so-called "inventory control", many people will interpret it as a "storage management", which is actually a big distortion. The traditional narrow view, mainly for warehouse inventory control of materials for inventory, data processing, storage, distribution, etc., through the implementation of anti-corrosion, temperature and humidity control means, to make the custody of the physical inventory to maintain optimum purposes. This is just a form of inventory control, or can be defined as the physical inventory control. How, then, from a broad perspective to understand inventory control? Inventory control should be related to the company's financial and operational objectives, in particular operating cash flow by optimizing the entire demand and supply chain management processes (DSCM), a reasonable set of ERP control strategy, and supported by appropriate information processing tools, tools to achieved in ensuring the timely delivery of the premise, as far as possible to reduce inventory levels, reducing inventory and obsolescence, the risk of devaluation. In this sense, the physical inventory control to achieve financial goals is just a means to control the entire inventory or just a necessary part; from the perspective of organizational functions, physical inventory control, warehouse management is mainly the responsibility of The broad inventory control is the demand and supply chain management, and the whole company's responsibility. Why until now many people's understanding of inventory control, limited physical inventory control? The following two reasons can not be ignored: First, our enterprises do not attach importance to inventory control. Especially those who benefit relatively good business, as long as there is money on the few people to consider the problem of inventory turnover. Inventory control is simply interpreted as warehouse management, unless the time to spend money, it may have been to see the inventory problem, and see the results are often very simple procurement to buy more, or did not do warehouse departments . Second, ERP misleading. Invoicing software is simple audacity to call it ERP, companies on their so-called ERP can reduce the number of inventory, inventory control, seems to rely on their small software can get. Even as SAP, BAAN ERP world, the field of

附录1:外文资料翻译 A1.1外文资料题目 26.22 接地故障电路开关 我们目前为止报道的接地方法通常是充分的, 但更加进一步的安全措施在某些情况下是必要的。假设例如, 有人将他的手指伸进灯口(如Fig.26.45示)。虽然金属封入物安全地接地, 但那人仍将受到痛苦的震动。或假设1个120V 的电炉掉入游泳池。发热设备和联络装置将导致电流流入在水池中的危害,即使电路的外壳被安全地接地,现在已经发展为当这样的事件发生时,设备的电源将被切断。如果接地电流超过5mA ,接地开关将在5 ms 内跳掉,这些装置怎么运行的? 如Fig.26.46所示,一台小变流器缠绕上导线 ,第二步是要连接到可能触发开合120 V 线的一台敏感电子探测器。 在正常情况下流过导体的电流W I 与中性点上的电流N I 准切的相等,因此流经核心的净潮流(N W I I -)是零。 结果,在核心没有产生电流,导致的电压F E 为零,并且开关CB 没有动作。 假设如果某人接触了一个终端(图Fig.26.45示),故障电流F I 将直接地从载电线漏到地面,这是可能发生的。如果绝缘材料在马达和它的地面封入物之间断开,故障电流也会被产生。在以下任何情况下,流经CT 的孔的净潮流等于F I 或L I ,不再是零。电流被产生,并且产生了可以控制CB 开关的电压F E 。 由于5 mA 不平衡状态只必须被检测出,变压器的核心一定是非常有渗透性的在低通量密度。 Supermalloy 是最为常用的,因为它有相对渗透性典型地70000在通量密度仅4mT 。 26.23 t I 2是导体迅速发热的因素 它有时发生于导体短期内电流远大于正常值的情况下,R I 2损失非常大并且导体的温度可以在数秒内上升几百度。例如,当发生严重短路时,在保险丝或开关作用之前,会有很大的电流流过导体和电缆。 此外,热量没有时间被消散到周围,因此导体的温度非常迅速地增加。 在这些情况下什么是温度上升? 假设导体有大量m ,电阻R 和热量热容量c 。 而且,假设电流是I ,并且那它流动在t 少于15秒期间。 在导体上引起的热 Rt I Q 2= 从Eq.3.17,在功率一定的情况下我们可以计算导体上升的温度差:

Computers and software were seen as the cure all for man y bu siness issues were some times applied blindly. S yste ms sometimes failed to solve the problem for which the y were designed for man y reasons including: ?Inability to sufficiently understand complex problems ?Not sufficiently taking into account end-u ser needs, the organizational environ ment, and performance tradeoffs ?Inability to accurately estimate development time and operational costs ?Lack of framework for consistent and regular customer communications At this time, the concept of structured programming, top-down design, stepwise refinement,and modularity e merged. Structured programming is still the most dominant approach to software engineering and is still evo lving. These failures led to the concept of "software engineering" based upon the idea that an engineering-like discipl ine could be applied to software design and develop ment. Software design is a process where the software designer applies techniques and principles to produce a conceptual model that de scribes and defines a solution to a problem. In the beginning, this des ign process has not been well structured and the model does not alwa ys accurately represent the problem of software development. However,design methodologies have been evolving to accommo date changes in technolog y coupled with our increased understanding of development processes.

外文原文 Mechanical Design Abstract: A machine is a combination of mechanisms and other components which transforms, transmits. Examples are engines, turbines, vehicles, hoists, printing presses, washing machines, and movie cameras. Many of the principles and methods of design that apply to machines also apply to manufactured articles that are not true machines. The term "mechanical design" is used in a broader sense than "machine design" to include their design. the motion and structural aspects and the provisions for retention and enclosure are considerations in mechanical design. Applications occur in the field of mechanical engineering, and in other engineering fields as well, all of which require mechanical devices, such as switches, cams, valves, vessels, and mixers. Keywords: Mechanical Design mechanisms Design Process The Design Process Designing starts with a need real.Existing apparatus may need improvements in durability, efficiency, weight, speed, or cost. New apparatus may be needed to perform a function previously done by men, such as computation, assembly, or servicing. With the objective wholly or partly In the design preliminary stage, should allow to design the personnel fully to display the creativity, not each kind of restraint. Even if has had many impractical ideas, also can in the design early time, namely in front of the plan blueprint is corrected. Only then, only then does not send to stops up the innovation the mentality. Usually, must propose several sets of design proposals, then perform the comparison. Has the possibility very much in the plan which finally designated, has used certain not in plan some ideas which accepts.
