Intelligent building communication network system composition and principle

Composition of intelligent building communication network system:

1. Comprehensive cabling system: With the deepening development of global social informatization and economic internationalization, people's demand for information **** enjoyment is becoming more and more urgent, there is a need for a suitable wiring scheme for the information age, and its primary feature is compatibility.

2. Computer network system: today's world is open, informatization, the wide application of computer networks is changing the way people work and live, and is further causing changes in the structure of the world's production and also to promote the development of the global information industry, scientific research, military, political, education and development of the country's economy, culture, education, and social life and other areas play an increasingly important role. It is playing an increasingly important role in various fields such as economy, culture, education and social life of various countries. Therefore, computer network technology has increasingly attracted a high degree of attention.

3. Multimedia system: the application of multimedia technology is the 1990s computer era characteristics, it greatly broadens the scope of computer applications. The development of multimedia technology can be roughly divided into two stages. In the first stage, multimedia systems basically work independently, typical applications such as computer-aided education, multimedia presentations and multimedia information retrieval systems, electronic publications. In the second stage, multimedia systems are to be operated on broadband networks, such as high-speed LAN, ATM (Asynchronous Transfer Mode), and B-ISDN (Broadband ISDN), etc., with typical applications such as videoconferencing systems, video-on-demand (VOD-Video on Demand), news-on-demand (NOD-- News on Demand), telemedicine and telemedicine. News on Demand), telemedicine and online shopping.

Principle:

The core of intelligent building is system integration, and the basis of system integration is the communication network in intelligent building. In the information society, a modern building, in addition to telephone, fax, air conditioning, fire and security monitoring system, a variety of computer networks, integrated services such as digital networks are indispensable. Only with these basic communication facilities, new information technology, such as electronic data interchange, e-post, conference television, video on demand, multimedia communications, etc. may enter the building. Make it a truly intelligent building. At present, in most of the things involved in relation to intelligent buildings. In the building intelligence project, should pay great attention to the information this element, and communication network is for the building of the various parts of the road to transfer information. With the increasing maturity of distributed intelligent building control system technology and application of popularity, in bas control will be further decentralized, in the network to pass more management information, system integration is more important, on the other hand, at present, due to the surge in people's information needs, as well as computer technology brought about by multimedia terminals, and other advanced terminal technology, the intelligent bottleneck of the intellectualization of an intelligent building often lies in its Communication network. It can be said that the level of communication network technology constrains the degree of intelligence of intelligent buildings.
