摘要
设计了一种基于GPRS网络的农村电网监测系统.该系统利用STC12C5410AD单片机片内定时器测量频率和相位差,与采样、放大、精密整流和滤波电路配合,通过瞬时采样法测量电压、电流有效值,并把正常运行信息和故障信息通过GPRS无线通信模块传送给数据中心.该系统具有体积小、价格低、功耗低、方便实用、稳定可靠等特点,是电网参数远程监测的一个有效的解决方案.
A monitoring system of rural power grids based on GPRS was designed. In this system, the differ- ence of frequence and phase was measured via the internal timer of MCU STCI2C5410AD. The normal run- ning information and fault information through GPRS wireless communication module would be sent to data center by instantaneous sample of effective value voltage and current to cooperate with sampling, magnif- ying, precision rectifier and filter circuit. The system had features such as small volume,low price, low pow- er consumption, convenience, stability and reliability. It would be an effective solution to remote monitoring of parameters of power system.
