摘 要：針對當前農村電網剩余電流故障難以定位的問題，提出了一種綜合ZigBee 技術和GPRS 網絡技術的農網剩余電流在線監測系統，通過傳感器、ZigBee自組網技術和GPRS技術來實現對農村用戶剩余電流、電壓的實時監測。使用剩余電流互感器、PIC 單片機、CC2530 芯片設計了采集器，使用CC2530、ATM 芯片和GPRS 模塊設計了集中器。通過ZigBee 組成的Mesh 網絡實現采集器和集中器的通信，通過GPRS 技術實現集中器與Web 服務器的通信。該系統能夠有效地對農網剩余電流進行遠程無線監測。

Abstract: 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 current 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.
Key words: rural power network; residual current; online monitoring system; ZigBee; general packet radio service
