摘要
为了方便检测CRH2型动车组APU所带负载的输出情况,自主研发了APU输出负载检测装置,重点介绍了检测装置中无线通信模块的设计原理和实现方法,通过无线通信功能模块,可以把检测到的输出负载信号以无线的方式传给服务器,从而便于数据的保存、查询和追溯,对于排查调试过程和实际运行中APU出现的故障具有很重要的意义。
In order to testing CRH2 EMUs output-load of APU, APU output-load testing device was developed. Design principle and implementation method of testing device's wireless communication unit were introduced mainly. Through wireless communication unit,output-load signal was transmitted to the server in the form of wireless, and the data could be saved, queried and traced, which had important significance to check the auxiliary power unit failure.
