摘　　要：该文主要探究露天矿地线连接状态实时监测及故障定位系统的设计要点,并对其故障检测与定位功能的实现情况进行测试。该系统由用于收集数据的检测监控装置和用于分析数据的主监控装置组成。系统采用PIC18F6620单片机作为主控芯片,当识别到地线连接状态异常或者是开关柜闭锁故障等特殊情况时,会进行声光报警并在液晶显示屏上提供故障相关信息,实现故障定位进而指导工作人员展开故障维修。从实验效果来看,该系统对常见的电阻超限、断路和短路等故障误报率控制在5%以内,并且故障定位精度可以达到99%,为露天矿高压供电系统的可靠与安全运行提供帮助。This paper mainly explores the design points of the system for real-time monitoring and fault location of ground wire connection status in open-pit mines,and tests the realization of its fault detection and location functions.The system consists of a detection and monitoring device for collecting data and a main monitoring device for analyzing data.The system uses PIC18F6620 MCU as the main control chip.When special circumstances such as abnormal ground connection status or switch cabinet locking failure are identified,it will provide sound and light alarm and provide fault-related information on the LCD screen to realize fault location.Then guide staff to carry out fault maintenance.Judging from the experimental results,the system controls the false alarm rate of common faults such as excessive resistance,open circuit and short circuit within 5%,and the fault location accuracy can reach 99%,providing the reliable and safe operation of the open-pit mine high-voltage power supply system.
