摘　　要：研制了一种适于煤矿不同电压等级和监控总线的电能质量远程监测设备。硬件选用TMS320F2812 DSP控制器,设计三相电压和电流检测、同步采样和频率跟随电路,配置通用串行接口RS-232,方便与现场总线进行数据交互。软件按事件位校验判定功能程序执行,通过快速傅里叶变换和频率跟踪获取电能质量特征参数。One remote monitoring device for power quality in different vohage grade and monitoring bus has been developed. Hardware has chosed TMS320F2812 DSP controller, and designed three-phase voltage and current detection, synchronous sampling and frequency following circuit. Hardware has configured universal interface RS-232 for interaction with field bus. Function program is performed according to the event bit calibration, power quality characteristic parameters are obtained by FFT and frequency tracking.
