【正文】 cess to information from the Inter. In recent years, enterprises, scientific research institutions in research and development of various Ether interface with the equipment at the scene, and these work interface has been applied to production at the scene. Naturally, Ether technology also entered the building automation system field of study. At present, Etherbased multisite for the building automation bus works into intelligent building information management works that link, that is, Ether bus technology. In some new development of the building automation system, directly into the Ether control layer, such as the Beijing Center building automation development of the Etherbased ENC20201P Intelligent Building Control System. In the building automation system using Ether is to realize the benefits from the management of equipment to the scene to control the patibility of the munication protocol and unified so that the system has expanded to more convenient, and the Intelligent Building of the other systems (munications automation systems and Office automation system) also integrate more easily. But it also shortings: First of all, the current development of Etherbased control system products more difficult, development costs and the cost is relatively high, the user can choose the manufacturers is very limited, monopoly profits higher research and development costs have not been digested All these lead to excessive prices and secondly, the realtime Ether, reliability, and other aspects have yet to be further improved. 3 building automation control system development trend analysis With technological development and economic trend of globalization, increased petition among enterprises, fieldbus technical standards will tend to unity, building automation system in the field bus munication protocol are bound to result tends to reunification. BAC standards in China will be widely used. At the same time, Ether technology because of its agreement pletely open, low cost, with the continuous indepth research, equipment Ether interface technology 13 matures, industrial Ether in the field of building automation will be widely used. At present, the building automation system of mainly concentrated in the construction of public resources, including power supply, lighting, air conditioning and cold and heat source, water supply and drainage, the liftcontrolled, security, fire protection, prehensive security, garage management, automatic meter reading , And other subsystems. With the continuous application of work technology indepth, safety, fort, energy saving, efficient working and living environment to constantly enrich the content, building automation system will be further indepth research, the scope will also be further expanded, will be extended to the family living space. All kinds of Ether interface of the work will promote household appliances and home automation makes possible a building automation system integration of a subsystem. With the development of intelligent buildings in particular, Ether technology in the building automation system of the traditional 3 A that will be watered down, the system tends to reunification, OAS, CAS, BAS boundaries will bee even more blurred. Systems integration will bee more simple, the cost of building intelligent system will decline further. The energy crisis has bee an urgent need to solve contemporary problems, has bee a hot current research. Intelligent Building of the energy system can be carried out to achieve scientific and rational distribution of energysaving purposes. Therefore, highly efficient energysaving building automation will also be an important direction of development of the system, which also includes the use of new energy sources, such as the current solar photovoltaic construction. How intelligent building in the use of photovoltaic power will also be intelligent building automation system research and development in one direction. Possible to omit a wireless work cabling, resource conservation, building automation work system also have greater research and application. Building automation system and work closely with the work technology, DCS and field bus in the current building automation system has been applied widely, but there are also some agreement, such as no uniform standards so that issues such as integration costs too high. BAC standard with its advanced technology, improve the architecture and the concept of open architecture intelligent system to bee the only area of ISO standards, will be widely used. Industrial Ether technology because of its fullopen, lowcost, highbandwidth, high stability and reliability, widely used to share the advantages of rich resources will bee a Building Automation System Research and Application of the hot spots. Home automation, intelligent home appliances work in the near future will also enter the building automation control system of applications. Energysaving research, development and utilization of new energy sources, such as wireless work technology in the field of application of intelligent buildings will also bee a building automation system of important research direction.
