基于GSM多通道远程遥控开关的设计

Design of Multi Channel Remote Control Switch Based on GSM Network

利用GSM网络,采用两片单片机为控制核心,设计了一种多通道远程遥控开关,包括受控模块和控制模块,受控模块包括第一微处理器、第二微处理器、GSM模块、多路继电器控制单元、时钟模块、存储电路和显示模块,控制模块通过用户手机发出控制指令短信或者通过按键模块输入定时开关时间来实现远程控制多组用电器的通断;详细研究了TC35i的AT指令、发送和接收短消息的功能、LCD的驱动、DS1302的时间显示、按键定时等问题,实现了系统软件设计,经实验测试表明,系统性能稳定、工作可靠、简单实用,具有广泛的应用前景。

Using the GSM network and two single chip microcomputer as control core, this paper design a multi channel remote control switch. The whole system includes a controlled module and a control module. The controlled module comprises a first microprocessor, second microprocessor, GSM module, multiple relay control unit, a clock module, a memory circuit and a display module. The control module can realize remote control multiple appliances on and off by two methods, one is the mobile phone user sends out the control command message, the second is the key module input timing switch time. The system realizes all the functions of the software design. The experiments show that, the system performance is stable, reiiable, simple and practical, and has wide application prospect.
