基于ARM的机车交直流接地故障诊断系统

针对目前机车电气线路接地故障解决方法的不足,提出一种基于ARM嵌入式系统的机车交直流接地故障诊断系统,重点介绍了系统的工作原理和硬软件设计;该系统采用精确的检测手段,独特的分析方法,能够快速、准确的定位接地故障点及故障类型,灵活多样的通讯方式,便于故障信息的储存和上传,以及机务段的统一管理;经实验证明,该系统检测精度高,运行稳定,具有很大推广价值。

Locomotive AC/DC Grounding Fault Diagnosis System Based on ARM

Aiming at the disadvantages of current means of solving locomotive electric grounding faults,a system of locomotive AC/DC grounding fault diagnosis based on ARM embedded System is introduced,the operating principle and hardware-software design are described in detail.Exact detection measure and particular analysis method are adopted in this system which could find the position and the type of grounding quickly and accurately,and various ways of communication made the storage and uploading of the fault information more convenient,as well as the unitive management of locomotive depot.Experiments showed that this system ran stably,accurately and effectively,and it is worth to be generalized.
