弱电技术智能建筑概论

弱电技术智能建筑概论内容摘要：

epresent all information techniques and obtain a technique such as the information.(spread feeling technique, and telemetering technique...etc.)The information technique is the technique foundation that the intelligence want to see a 4 C technique to really bee the information technique construct in the applied main technique in the intelligence, the 4 C technique is also a main intelligence to construct a weak electricity technique. The information technique is used as intelligence to construct a weak electricity technique, after applying to an intelligence building, people39。 s work, lives will take place huge variety, can carry out much service in home or like electronic merce, online shopping, can see telephone, television meeting and long range education, long range medical treatment and family to transact, the upper stream drama, video frequency point sow, transact an automation, thing industry to manage an automation, equipments automation, convenience of correspondence method etc..Make people be placed in an information society efficiently, fortable and convenient building environment in. 2, modern calculator technique The calculator technique is information to handle a main technique in the is importance of information technique to constitute part, the calculator handles the ability of information to just and quickly the calculator39。 s multimedia technique passes the calculator to the informations, such as speech, writing, data and picture...etc. and synthesizes a processing and make people get more perfect keep the prehensive information of view. Along with Inter|the Intra and information superhighway, data turned a technical development, calculator technique and correspondence technique, multimedia technique closely fusion to consumedly open widely an information technical application together. The huge function of modern calculator technique also expresses system at the calculator work, for example calculator bureau area s, such as Inter and Intra...etc. and wide area work . The calculator work technique is positive along proceed together and handle a distribute type a direction of the distribute type calculator work technique is a kind of new form that many calculator machine systems unite a the distribute type calculator system emphasizes is a distribute type calculation and proceed together a processing, not only the whole work system hardware and software resources share, also want the share of task and characteristics BE, the system39。 s adoption unifies of distribute type operate system, many pieces according to processing system of the in general use parts anically constitute a system that has whole function, each soft hardware resources manages have no obvious of principle and subordinate management system weighs to reach to many machine cooperation systems, the permitting of redundancy wrong ability all has very great improvement and exaltation, therefore the system has a larger importation|output ability, higher credibility, sooner respond to, and the system cost more economic. The calculator technique is extensively applying to an intelligence building, bee an important technique that the intelligence constructs a weak electricity in the intelligence by information, correspondence management, control etc. there is important function in CNS, OAS and example, construct to correspond by letter work system in the intelligence in, the main stem tie area of calculator work system bees one of the main correspondence a highspeed main stem work technique to mainly have rapid ether , FDDI and ATM and various type rapid work with each other and connect an equipments etc..General area in the bureau adopts ether and wreath type to wait the card for businesses are needed inside the in order to contented building of the information deliver and building outward one of the correspondence main works of boundary is also the calculator that makes use of area wide area work sW, such as and Inter...etc. in bureau to undertake together. The calculator technique is the core technique that constructs equipments calculator work as foundation(for example LONworks, and BAC...etc.) to link calculator and the air condition, and elevator...etc. inside the building various equipments pletion equipments to automatically supervise and control management and system integration。 Complete the automatic control to guard against the system to the fire fight and the safety and management. The calculator technique is also the predominant function with indispensability, make people make use of a calculator to keep the house and then can plete transacting of various layer business in the aspects of transacting to automate, for example, owner to the thing industry of each kind of equipments in the building management, and luck camp...etc., the all levels what public official carried on various management that transact a kimono duty, and various information service bining of calculator technique and correspondence technique, multimedia technique is creating the condition that the family transacts. 现代通信技术 通信技术是现代信息技术的一个重要组成部分，通信技术的任务是延长人的记忆器官存贮信息的功能。 通信的本质是快速、准确地转移信息。 通信技术正在沿着数字化、宽带化、高速化和智能化、综合化、网络化的方向迅速发展。 例如通信网络与多媒体联机数据库和计算机组成一体化高速网络的信息高速公路，向人们提供语音、数据、图形图像等快速通信，实现信息资源高速度共享。 通信业务种类不断增加，已由传统的电话、传真等基础通信业务发展到数据、图形图像、可视电话、会议电视、多媒体等通信业务。 现代通信技术包括 了综合业务数字网 ISDN（ Integrated Services Digital Network）技术，即NISDN/BISDN 技术、宽带多媒体网技术、异步传输 ATM 技术、同步数据系列 SDH 技术、接入网技术、互联网 Inter/Intra、 IP（ Inter Protocol）通信技术、卫星通信技术、移动通信和个人通信技术、数字微波通信技术、数据通信技术等等。 通信技术应用于智能建筑形成了智能建筑通信网络系统 CNS，通信网络和通信技术是智能建筑弱电技术的重要组成部分，也是其它弱电技术 的基础。 通信技术和通信网络系统用以实现建筑物或建筑群内、外信息获取、信息传输、信息交换和信息发布。 通信技术和通信网络系统是实现智能建筑通信功能和建筑设备自动化、办公自动化的基础，通过多种通信网络子系统和相应的各种通信技术对来自智能建筑内、外的语音、数据、图像等各种信息进行接收、存贮、处理、交换、传输等为人们提供满意的通信和控制管理的需求。 现代自动控制技术 自动控制技术属于信。
