基于ZigBee和GPRS网络的农网剩余电流在线监测系统

针对当前农村电网剩余电流故障难以定位的问题,提出了一种综合ZigBee技术和GPRS网络技术的农网剩余电流在线监测系统,通过传感器、Zig Bee自组网技术和GPRS技术来实现对农村用户剩余电流、电压的实时监测。使用剩余电流互感器、PIC单片机、CC2530芯片设计了采集器,使用CC2530、ATM芯片和GPRS模块设计了集中器。通过Zig Bee组成的Mesh网络实现采集器和集中器的通信,通过GPRS技术实现集中器与Web服务器的通信。该系统能够有效地对农网剩余电流进行远程无线监测。

Online Monitoring System of Residual Current in Rural Power Network Based on ZigBee and General Packet Radio Service

Aiming at the problem that the location of current residual current faults in rural power network is difficult to determine, this paper raised an online monitoring system of current residual current in rural power network with a kind of comprehensive ZigBee and general packet radio service (GPRS) network technology. The residual current and voltage in rural users were monitored in real time through the residual cur-rent transducer, ZigBee self-networking technology and GPRS technology. This paper designed a collector with the residual current transducer, IPC microcomputer and CC2530 chip and the concentrator was designed using CC2530 chip, ATM chip and GPRS module. The data between collector and concentrator was transferred through the Mesh network constructed by ZigBee. The data between concentrator and Web server was transferred through the GPRS network. The developed system can carry out long-distance wireless monitoring for the residual current in rural power network effectively.
