随着对电能传输过程保质量、高效率、强可靠的要求，时间同步设备对于电力系统安全运行以及故障检测尤为重要。文中介绍了以STC12C5A60S2单片微型计算机为控制器，NEO 6M 为全球定位(GPS)授时定位的配电监测系统。首先，对系统的功能实现做了整体框架设计；其次，着重对配电参数的采集、GPS授时定位模块做软硬件设计以及进行PROTEUS仿真；然后，通过液晶显示器（LCD）12864实现GPS时间、地理位置显示；最后，设计上位机软件进行试验，完成整个系统功能的实现。

With the power transfer requiring ensuring quality,high efficiency,strong reliability,time synchronization equipments are particularly important for the safe operation and fault detection of power system. The distribution monitoring system based on single-chip controller STC12C5A60S2 and NEO-6M GPS timing module is introduced. First, the overall framework of the system is designed to achieve the paticular functions; second, hardware and software design is made mainly on the acquisition system of distribution parameters ，GPS timing and positioning module, PROTEUS simulation is done; then, GPS time and position displaying through LCD12864 is realized; finally, PC software is designed to achieve the the entire system function.
