短消息控制器在中央空调远程监控中的应用

Application of SMS Controller in Remote Monitoring and Controlling for Central Air-conditioning

针对目前中央空调控制系统远程监控的需求,结合单片机技术和GSM无线通信技术,提出了一个基于短消息方式的远程监控系统的设计方案;该系统采用自主研发的短消息控制器以实现远程监控功能,软件部分采用C语言进行模块化编程;文章具体介绍了系统的硬件实现和软件设计,并给出了部分代码;该系统具有硬件实现简单、低功耗、软件可扩充性强以及控制方式灵活有效等特点,其设计思想对于当前中央空调控制器的设计有相当的参考价值。

In accordance with the needs of central air-conditioning control system, using the microcontroller technology and GSM （Global System for Mobile） technology,a scheme of remote monitoring and control system based on SMS（Short Messaging Service） is stated. The system uses the SMS controller to realize the function of remote monitoring and controlling, and uses C language to program codes in modularization structure. Focuses on the design of hardware and software,and some codes are provided. The design mainly features concision of the hardware, low power consumption. At the same time, the extensibility of the software is strong as well as flexible, efficient in the way of controlling. The idea of designing has particularly provided valuable experience for nowadays design of central air-conditioning controller.
