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。
Locomotive to the vehicle to provide DC600V or AC380V power supply, after the assembly of locomotives need to test the power connector socket power failure. At present, the detection methods are mostly multimeter manual measurement, maintenance staff of the high risk factor. Accordingly, a portable locomotive power supply tester based on LPC2368 is designed, which can detect and display the voltage of locomotive power supply and judge the fault of the wrong connection or open circuit, improve the accuracy and speed of fault diagnosis and reduce the risk of maintenance personnel.
