Application of and Fault Identification and Repair for Inter-station Safety Information Transmission System of Beijing-Tongliao Railway Under Electrification

为分析站间安全信息传输系统潜在的故障及处理流程,提高站间安全信息传输系统故障场景辨识的全面性,以京通铁路电气化改造项目采用的CXG-js型站间安全信息传输系统为例,提出基于故障模式引导词集和故障对象引导词集的站间安全信息传输系统故障分析方法。分析站间安全信息传输系统的功能、工作原理和组成结构,提取系统的故障模式引导词集和故障对象引导词集,采用组合方法生成系统全面的故障集,分析每类故障的故障现象、判断方法、处理方法和对行车的影响,提出对故障的处理流程,为系统、全面地辨识站间安全信息传输系统潜在的故障场景提供理论支撑。

In order to analyze the potential faults and repair process of the inter-station safety information transmission system and improve the comprehensiveness of the fault scene identification of the inter-station safety information transmission system, taking the CXG-js inter-station safety information transmission system of Beijing-Tongliao Railway Project as an example, this paper proposes a failure analysis method of the interstation safety information transmission system based on the failure mode guide word set and the failure object guide word set. This paper analyzes the function, working principle and composition structure of the interstation safety information transmission system, extracts the failure mode guide word set and failure object guide word set of the system, generates a systematic and comprehensive failure set through combination method,analyzes the failure phenomenon, judgment method, failure repair method and the impact of failure on train operation of each type of failure, and proposes the failure repair process, which provides theoretical support for systematic and comprehensive identification of potential fault scenarios of inter-station safety information transmission system.
