接地电阻阻值远程测量系统

A remote measurement system of grounding resistance value

针对接地电阻测量仪无法实现接地电阻的远程测量及阻值的实时监控,设计了一种运用钳表法进行远程测量的系统。该系统以单片机MSP430F149为核心,利用SIM900A模块进行数据传输,使用VS2015编写上位机管理软件,从而实现了多节点接地电阻的远程实时接入测量、监控及数据的管理。与已有的测量系统相比,该测量系统消除了外部因素的影响,提高了测量精度,使用更加便捷。

As the grounding resistance measurement instrument fails to measure the grounding resistance remotely and monitor the resistance value in real time,a remote measurement system has been designed by adopting the clamp meter measurement method.With the core of the SCM MSP430F149,the system applied the module SIM900 Ato transmit data and used VS2015 to write the management software running on host computer,which has made remote real-time measurement,monitoring and data management of the multi-node grounding resistance come true.Compared with the existing measurement systems,the new alternative has eliminated external effects and improved measuring accuracy,with easier access to use.
