基于嵌入式的客房变风量空调系统智能控制器设计

The Intelligent Controller Design of VAV Air Conditioning System Based on Embedded Processor S3C2440A

介绍一种基于嵌入式处理器S3C2440A的变风量(VAV)空调系统智能控制器的设计方法。VAV空调系统室温实时控制采用模糊PID控制算法,利用嵌入式技术搭建Web服务器,实现空调系统的远程监控。软件设计上,运行Linux操作系统,移植图形用户界面开发环境Qtopia和Qt/E,采用多进程和多线程编写程序。经过测试表明,整个控制系统性能良好。

Introduces a design method of intelligent controller of VAV air conditioning system based on embedded processor S3C2440A. The VAV air conditioning system adopts fuzzy PID control algorithm to real-time control room temperature. Builds a Web server by means of the embedded technology to realize remote monitoring of the air conditioning system. In the soft＇ware design, runs Linux operating system, transplants graphical user interface development environment with Qtopia and Qt/E, and uses multi-process and multi-thread programming. The test results show that the whole control system has good performance.
