摘要
传统的接地电阻测量方法存在诸多的缺陷与不足,目前还是以人工定时定点测量为主。基于此,设计了一种简易的接地电阻在线测量方法,可实现在线测量和实时响应,测量系统由单片机产生的激励信号、功率放大电路、采集信号处理电路、4G无线通讯模组和云平台设计模块组成。这种测量方法简单,易于操作,同时可降低人工处理成本,具有一定的市场应用价值。
The traditional method of grounding resistance measurement has many defects and deficien-cies,and the manual measurement at fixed time and fixed site is still the main method at present.Based on this,this study designed a simple on line grounding resistance measurement method,which can realize online measurement and real-time response.The measurement system consists of five mod-ules:excitation signal generated by the single chip microcomputer,power amplifier circuit,signal ac-quisition and processing circuit,4G wireless communication module and cloud platform design.This measurement method is simple,easy to operate,and can reduce the cost of manual processing,and has a certain market application value.
