铁路信号联锁设备的故障诊断

信号联锁设备的故障诊断对铁路运输行车安全具有很大影响。故障诊断技术的优劣,直接影响信号设备的安全性、可靠性,危及行车安全,甚至导致行车事故。首先介绍了四类联锁设备故障诊断技术：传统故障诊断方法、基于信号处理的方法、基于解析模型的方法和人工智能的方法。其次,给出了故障诊断技术的典型应用,即故障处理流程图法、故障树分析法、故障诊断专家系统以及故障诊断与容错控制等。最后针对联锁设备的特点,提出了诊断领域存在的问题和未来的研究重点。

Fault diagnosis for railway signal interlocking- equipment

Fault diagnoses of signal interlocking equipment have great influence safely on the safety of railway transport.What it is good and bad directly affects the safety and reliability of signal equipment,endangers running safe,even causes train operation accident.This paper first introduces four kinds of approaches for the fault diagnosis: the method of traditional fault diagnosis,the method signal of model,the method of analytical model and the method of artificial intelligence.Secondly,some typical applications of the fault diagnosis are discussed on this paper or the method of fault handling flowchart,fault tree analysis,expert system of fault diagnosis and fault diagnosis & fault tolerant control and so on.Finally,potential problems in this area are outlined and the further important research directions are pointed out.
