Abstract
With the development of electronic and informational techniques, sound and images techniques, communication techniques, etc.,the automation level of buildings is also developed. Concentrated and integrated automation control systems are formed from distributed and separated one. Intelligent Building(IB) flourished on this background, the result of many field and subjects, which deals with such techniques as architecture, electric, communication, compute,automation control, air-condition and management, etc.
On the base of full-scale discussion of intelligent Building(IB),this paper introduces the structure of IB in detail and three main aspects such as the Buildings Automation System(BAS) which is one of the most important three parts of Intelligent Buildings. From the point of system design, a scheme of building automation system base on the application level is brought forward a set of monitoring tables for system is designed, which can help forming control substations. This paper also discusses the hardware and software of the whole system and their configurations, and PROFIBUS-DP─a standard communication protocol. The supervisory system of every subsystem is set up, and then on the base of function analysis of the supervisory system, the whole structures of the system are established
The main purpose of the essay is to propose a way that applies the fuzzy control technique to air-conditioning control of intelligent building.In detailed,we choose cheep and high integrated single PIC to buil hardware and software,and use PID control and optimized fuzzy control to realized high efficiency and low dissipation which are very important for air-conditioning design in modern intelligent building.
The operation of the system is reliable. It also meets the market demand.
