The Study Of Embedded Controller Applied To The Moniter System Of Central Air-Conditioning

The monitor system of air-conditioning, which is an import part of BAS, is becoming more important. Recently, the design of BAS is complex, and the power use of air-conditioning system is more and more high. To achieve the efficient control and management of the air-conditioning system, as well as the efficient use of the technology of saving energy, it is very important to apply embedded controller and computer control technique to the monitor system of air-conditioning.In this paper, the embedded controller is studied and applied to the monitor system of central air-conditioning. It realizes data collection and control. The design of embedded controller adopts C8051F020 MCU, and change standard signal of 0-10V, 4-20mA and 0-100oC to standard MCU signal.The hardware of this monitor system adopts SIEMENS Embedded Controllers including Modular Building Controller,Modular Equipment Controller, and so on. The software adopts APOGEE Insight of SIEMENS.This paper is based on the central air-conditioning monitor system project of environment protecting,monitor integration building in Tianjin environment protecting bureau. It makes the design and actualizing scheme. This paper includes: the basic concepts and development trend of intelligent mansion, its problems, the requirement of the BAS, the buildup of the monitor system of air-conditioning and its principle. And the monitor system of air-conditioning is implemented. Its design method is introduced. Finally, it discusses the problem of saving energy of intelligent mansion, and presents suggestions on the continual development of the intelligent mansion.
