摘要
针对很多GSM模块可以通过GSM/GPRS接入互联网这一特点,设计了一个以索尼爱立信公司的GR47无线模块作为接收模块,89C51作为主控制器的家电短信远程控制系统。介绍了该系统的硬件构成,详细描述了在PDU模式下用AT命令实现短信对家电的远程控制的过程,以及在VC++6.0环境下系统软件的设计流程。研究结果表明,该系统具有广阔的推广应用前景。
Aiming at lots of GSM modules that can be connected to Internet by GSM/GPRS, a SMS remote control system for household appliances was designed, based on the receiving module of GR47 and microprocessor of 89C51. The hardware structures of the system was introduced, the procedure that short messages controlled household appliances remotely with AT commands on the basis of PDU mode and the software design flow with Visual C ＋ ＋ 6.0 were described detailedly. The experimetal results show that the system illustrates a good prospect of application and extension.
