摘要
文章基于和谐机车TGY电源负载特性的研究,设计了一种新型的负载特性测试系统。该系统主要运用权电阻电路设计思想,采用PLC控制技术实现干阻负载的连续可调。并利用MODBUS串口通信协议,实现上位机监控软件对实验数据的实时记录监控。
This paper based on the research of HXD1 locomotive＇s power load character to design a new load characteristic system.This system mainly used the right resistance circuit design idea and PLC control technology to achieve continuously adjustable of dry re- sistive load.The experimental data is monitored in real time by PC monitoring software using serial communication protocol of MOD- BUS.
