【摘要】 文章介绍了一种基于GPRS的远程传感控制系统,GPRS模块采用MC52i,单片机选用STC12C5412AD,温度传感器采用DS18B20,利用MC52i通信模块的短信息功能实现远程单片机与监控中心之间数据和控制指令的双向通信。该系统以GSM网络为平台,结合单片机系统和串口,实现了远程无线数传(DTU)的交换,通过硬件电路及单片机程序设计,实现了弱电控制强电、远程控制、信号的实时性上报或查询等功能,具有一定的实用价值。更多还原

【Abstract】 This paper introduces a new kind of remote control system based on GPRS module,in which MCU model STC12C5412AD is interfaced with the temperature sensor DS18B20 and the GPRS module MC52i.The messaging function of MC52i is used to realize dual communication of data and command between remote MCU and control center.Based on GSM network,the system combines MCU system and serial to realize the exchange of remote wireless data transmission.Moreover,such functions as remote control,weak current controlling strong electricity,real-time signal reporting and query are achieved by hardware circuit and MCU program design.The system is really of some practical value.更多还原
