基于Zigbee技术的线路故障定位系统

Study on Line Fault Location Based on Zigbee Communications Technology

设计了一种基于Zigbee通信技术的线路故障定位系统.该系统首先利用电流传感器对电路中的电流进行采集,并通过Zigbee技术将测量信号传入通信单元,然后通信单元利用GPRS系统将测量信号输入总控单元,总控单元通过对不同位置的电流信号变化进行检测,以实现对故障线路的定位.模拟试验结果表明,该系统能够对线路的故障实现准确定位.

A new line fault location system based on Zigbee communications technology is designed. Firstly, the current in the line is measured by current sensor, and the data are sent to communication unit by Zigbee modules. Then the data are treated and sent to the main control unit by GPRS. Based on analyzing data change of different location current sensors ,the fault location is realized in the control unit. It can be seen from the testing results that the developed system can locate the fault on overhead power line.
