基于GSM的中央空调末端控制器研究

Study of central air-conditioning terminal controller based on GSM

针对当前中央空调末端普遍采用固定时间调度方式,基于ARM9、GSM网络和PID控制策略设计了远程中央空调末端控制器,通过短消息实现末端装置远程启/停和室内温度查询。实验结果表明,末端装置可以通过短信按需要开闭,实现节能。

In today＇s central air-conditioning terminal control systems, modes still are fixed-time scheduling. In this paper, we designed a remote controller of central air-conditioning terminal based on ARM9, PID control strategy and SIM card GSM net. The controller could remote start/stop a air-conditioning terminal or inquiry of indoor temperature through short messages. The experiments showed that the terminal controller is able to start/stop by user needs, and achieved the purpose of energy-saving.
