一种适用于农村配网的“看门狗”型远程用电管理终端的设计

Design of watch-dog type remote electricity management terminal applicable to rural distribution network

针对目前农村配网发展面临的问题,提出了一种适用于农村配网的'看门狗'型远程用电管理终端系统。该系统通过用电管理程序实现预付电费、欠费告警、续费恢复供电的功能;智能终端实现电流、电压数据的实时计算,保护逻辑程序根据该数据作出判断,实现'看门狗'的作用。并详细介绍了该系统的硬件电路结构及软件设计流程。该系统融合了保护与用电管理自动化为一体,为农网配电的智能化发展提供参考方案。

In view of the problem of the present countryside＇s net development facing,this paper proposes ＂the watch-dog＂ long-distance electricity consumption manangement terminal system.This system applies electricity consumption executive program to realize the prepay electrical bill,the money owed warning and restoration of power supply.The intelligent terminal implements the real-time computation of electric current and the voltage data,protects the logical program to make the judgment according to the data,and thus realizes ＂the watch-dog＂ function.This system＇s hardware circuit structure and software design flow are introduced in detail.This system combines protection with electricity utilization management automation and provides a reference for the intellectualized development of agricultural network power distribution.
