基于GPRS的农村电网远程监控系统

Long-range Monitoring System of Rural Distribution Based on GPRS

针对农村电网通信系统对数据传输实时性和可靠性的要求,提出了基于GPRS技术的无线通信方案。该方案以GR 4 7模块为核心,以相应的单片机为控制器,设计了GPRS终端的硬件系统和软件系统。经过实际测试,在数据的传输速率、数据的误码率以及系统建立连接等方面均达到了设计要求。测试证明,GPRS技术完全可以应用在农网监控系统中。

As the requirements of rural distribution on the reliability and the timeliness of communications system, this paper put forwards a wireless communication project based on GPRS. This paper designs the hardware and software of GPRS terminal by using the GR47 module as the core and the corresponding single chip computer as the controller. The testing results show that the data transmission speed, the byte error rate in the data transmission, and the system setup operations all satisfy the system requirements. It has been convinced that the GPRS technique can be used successfully in the Long - rang monitoring system of rural distribution.
