Application Of Wireless Local Area Network In Intelligent Buildings

The design and constructions of the intelligence buildings (IB) is a typical system integrated. With the technical developments, such as computer network technique, information technique, Communication technique, system engineering and the control automation techniques and the comprehensive arrange wire, etc., the system integrated of the intelligence buildings just turn toward network and information, how to use the latest technique and product, became the most important study issue of intelligence buildings designer with the standpoint of-uthe best function of minimal devotion ".How to assurance each sub system in the intelligence buildings to earn, out fast, efficiently, moderately, is the point of the research. To carry out the target, must stabilize the information channel and computer network system platform which is fast and safe and dependable. The key that resolves the problem is how to make use of the most advanced modern communication and computer network techniques in the system.The Wireless Local Area Network (WLAN) technique develops in recent years quickly, has the more successful application in the every profession. The Wireless Local Area Network technique has unique advantage in the intelligence buildings, this will make it acquire more extensively applied space. In the future, the intelligence building system integrated platform must be the admixture systems which include the wire and wireless computer network system; the admixture computer system will have the most perfect function of the lowest investment and the widest development.The intelligence building must be the inevitable direction of the Construction, how the make use of the technique characteristics and advantage of the Wireless Local Area Network technique, to perfect and strengthen various function of the intelligence building is the most urgent task of current intelligence building research. The topics of application of the Wireless Local Area Network technique, not only have academic value, but also have higher economy value.The purpose of the thesis is to look for the possibility of resolving this problem and the method of carrying out the project attain to satisfy the basic function of the intelligence buildings, and how to use the Wireless Local Area Network technique to attain considerable economic performance and practical values.The two greatest techniques core of the thesis respectively are: the Intelligence Buildings, the Wireless Local Area Network technique. The Intelligence Building is the body of the Wireless Local Area Network to carry out. The Wireless Local Area Network is a new key technique of in the Intelligence Building design.This thesis analyzed the problems such as basic concept, key technique, related agreement standard and the network safety of the Wireless Local Area Network in detail. For the example of actual integrated engineering, this thesis also analyzed the plan design application of the Wireless Local Area Network in the Intelligence Buildings.The main research contents include follow issues:On the basic of annlysis of intelligence buildings' characteristic module, thepositionand role of WLAN in IB is studied in the thesis, and comparaton oi' the advantages and weakness of wireless network technogic and wire network technogic in intelligence buildes is carried out.Point at the needs and status of network techniques, the admixture network of "wireless + wire" adopted in IB is proposed. Which can meet the demand of applications with great continue development and economize. It satisify the intelligent, flexible and economize of IB, have practice engineering value.Analysis of Function demand is carried out in the thesis. Design plane of the studied topic is proposed. System planning is fulfilled and explicit the design aim and principle. The kilomega etwork is adopted as the main structure of the system.Accomplish the planning of WLAN in IB. design and realization of wireless network, access of wireless network, admixture network, and protocol of wireless network, safity. network management a...
