To be followed by the construction of electrical design basis for the construction of electrical taken as olid step toward standardizationIntelligent technology is only a means of building is equipped with intelligent functions,stressing efficiency, low energy consumption. Cleaner, in the true realization of peoplecentered, under the premise of achieving energy conservation, enhance building39。s work, studying and living with a security guarantee. CCTV Surveillance System from analog to digital direction of the past, size of the entire security system is also moving system, digital,integrated direction(3) munication network technology Intelligent Building munications networks, including puter networks, twoway cable TV transmission networks and telephone munications network. The first two intelligent building as a broadband backbone network to focus almost all of its information technology and information resource management Almost all of the users are connected to the station. Before the mid1990s, in the 20th century, there is a market for all types of networks and users. But in the late 1990s, with reasonable investment Ethernet wiring flexibility, and superior performance, ease of maintenance and use of such advantages, ICT networks gradually in the list. Ethernet transmission rate, from the initial 10Mbps,100Mbps to even higher rate. Intelligent Building Telephone Network (ISDN, xI) SL), currently used for voice munication, also both data and images narrowband data munications,it makes people through munication networks, TV, telephone conference and other functions. Smart Access technology is the key to building links with the outside, it makes visible the world is being smaller and smaller. people39。s market, because of its excellent performance, Intelligent Building to the domestic market, a new concept, new technology, and immediately aroused tremendous repercussions in the construction industry. has been widely used in all types of intelligent building. To meet the network transmission bandwidth and speed the development of new products PDS fresh from the first three lines, Category 5 to 6 lines, or even in advance of the standard seven Cabling System products to meet the demand for gigabit networks. With a transmission rate of the network upgrade, in order to adapt to its fiber network has already been put into the development of the 10G market, The new multimode and singlemode fiber transmission medium as a good will be widely used. Copper from five to three over the five,six or even higher categories, from copper wire to fiber optic cable, technology and products continuously updated. Ting fully reflects the rapid development of the intelligent building and the application of new technologies and broad prospects.(5) System Integration Technology Intelligent Building of each subsystem in general linking their respective networks, The operation is expected to plete their work stations, but has not yet reached the sharing of information resources. In order to achieve efficient management, sharing of information resources between the various subsystems, and system integration. In the systems integration process, the choice of platform integration, network structure,The scope of integrated subsystems are different, with different integration models. With puter technology, network technology, control technology, the development of display technology, Building equipment monitoring and control system and other systems linked through puter networks. The resulting construction equipment monitoring system based systems integration mode. There is equality in their respective systems integration, and establish a network management system integration. as a subsystem to lower the scene control network integration and equal manner. Realtime data subsystem, open, industrystandard interface, converted into a uniform format stored in the database or server system network management system to achieve unified management subsystem procedures, monitoring and information exchangeSystems integration, in order to achieve agreement on the opening of the linkage between the various subsystems related to the control and information sharing. improved management efficiency, enhance capacity to deal with emergencies, and the purpose of saving energy and manpower savings. This is the construction equipment management system (BMS). System integration is not our aim, but to enhance the buildi
