嵌入式系统下位机故障定位及分析方案研究

针对铁路信号领域嵌入式系统下位机的架构,梳理了嵌入式系统下位机的相关故障分类,并根据不同种类的故障,有针对性地给出相应的故障定位及分析方案,详述了每种故障定位及分析设计的原理和实现方法,最后提出了一种下位机故障定位及分析的综合方案,并将该综合方案用于铁路信号领域iBase22-TSP型轨旁安全平台的下位机故障定位中,改善了TSP平台的下位机故障定位和诊断维护功能。

Scheme of fault location and analysis for lower computer of embedded system

Aiming at the architecture of the lower computer of the embedded system in the field of railway signal, this paper sorted out the fault classification of the lower computer of the embedded system,gave the corresponding fault location and analysis scheme according to different kinds of faults, detailed the principle and implementation method of each fault location and analysis design, and finally put forward a comprehensive scheme of fault location and analysis for the lower computer,which was applied to the fault location of the lower machine of iBase22-TSP trackside safety platform in the field of railway signal. It improves the fault location, diagnosis and maintenance function of the lower computer of TSP platform very well.
