Based Network Platform, Gas Central Air-conditioning Control System

With the quick development of city of china,Central Air Conditioning will be the best options for people.This thesis formulates a stable Control System based on Center air conditioning's structure and theorem.Not only we apply frequency speed regulation , Fuzzy Control, concentrate control technique and calculator network technique in the system ,but also we can control the system through Modem or Internet.So the control system has the feature of intelligent and Networking.The thesis mainly discusses the designs of structure for the Control System, the designs of communication protocol, the options of the Control Scheme through Internet, the research of fuzzy mathematics theory.The main work and research results of the thesis includes the following:1. This thesis detailedly discusses the designs of Central Air Conditioning Control System , introduces the exploitation of Centralize Controller based on μPSD3234A and the exploitation of Outdoor Controller based on MC16/62.2. The Control System can be controlled through Modem or Internet.This thesis detailedly discusses realization of Serial Port Networked Server.3. The Control System make use of fuzzy control technique , concentrate control technique,calculator network technique, frequency speed technique.4. The romote monitoring software by vc++.The running results indicates that the system has reasonable control scheme,high operating reliability,advanced control algorithm,friendly man-machine interface and operating convenience.
