摘要: 为防止列控中心(TCC)设备故障的发生,根据列控中心设备的失效机制建立动态事故树(DFT),采用马尔科夫理论进行可靠性分析,提出基于马尔科夫链的列控中心可用度及剩余使用寿命预测模型。由各系统状态转移关系得到状态转移图,进而写出状态方程,并对其求解得到可用度、可靠度分布函数和剩余使用寿命公式。研究结果表明:列控中心设备的薄弱环节为驱动采集单元(PIO)>冗余电源(DY)>TCC与TC通信接口(CI-TC)>安全主机单元(SCU)>其余各通信接口;考虑共因失效后列控中心的稳态可用度达到设计标准,且列控中心设备的平均剩余寿命为186.256个月。

Abstract: In order to prevent occurrence of equipment failure in the TCC, according to failure mechanism of TCC equipment, DFT was established, and reliability analysis was carried out by Markov theory, availability and remaining useful life prediction model of TCC based on Markov chain was proposed. State transition diagram was obtained from state transition relationship of each system, and then state equation was written out. Availability distribution functionand,reliability distribution functionand and formula of remaining service life were obtained. The research shows that weak link of TCC equipment was port input/output(PIO)>dian yuan(DY)> CI-TC>secure centre unit(SCU)>other communication interfaces. Considering CCF, steady-state availability of TCC reaches design standard, and average remaining life of TCC equipment is 186.256 months.

Key words: Markov chain, train control center(TCC), availability, remaining life prediction, common cause failure, dynamic fault tree(DFT)
