摘要
机车向车辆提供DC600V或AC380V电源,对机车组装完毕后需要检测其电力连接器插座供电是否故障。目前,检测方法大多是采用万用表人工测量,检修员的危险系数高。据此设计了基于LPC2368的便携式机车供电检测仪,能检测并显示机车供电各项电压,并判断出接错或断路故障,提高了故障诊断的准确性和诊断速度,降低检修员的危险性。
The power DC600V or AC380V is supplied to vehicles by Locomotives, and the fault detection of power supply connector socket is a part of the maintenance process, after assembling of Locomotives are completed. Recently, the manual measurement using multimeter is the most widely used, which causes a high risk level for maintenance. In this paper a portable detector of power supply for locomotive based on LPC2368 is designed to measure and display the power supply voltage of locomotive and diagnose the fault wire and open circuit at the same time, which improve the accuracy and speed of diagnosis and reduce the detection risk level.
