摘要
铁路信号系统集成化、自动化的发展,能为电磁干扰的产生、耦合提供良好环境,信号系统受到强电磁干扰后会影响到整个系统的安全。研究信号系统在受到电磁干扰后"故障导向安全"的能力,以电磁干扰与ZPW-2000A自动闭塞系统安全的关联性为例,采用故障树和层次分析法分析发送器和接收器故障的发生概率和"故障导向危险侧"的发生概率,得出电磁干扰与ZPW-2000A自动闭塞系统安全的关联性,为铁路信号其他系统的安全评估和电磁干扰的防护提供参考。
The development of integration and automation of railway signal system provides a good environment for the generation of electromagnetic interference and coupling.The signal system is easily affected by the strong electromagnetic interference,which will influence the safety of the overall system.This paper mainly researches the railway signal security of the narrow definition,namely“fail-safe”after exposure to the electromagnetic interference.in order to study the correlation of the electromagnetic interference and system security.Taking ZPW-2000A automatic block system as an example,it uses the fault tree analysis(FTA)and analytic hierarchy process(AHP)to analyze transmitter and receiver failure probability and the probability of fault orientation“dangerous side”.It reaches the correlation of electromagnetic interference and ZPW-2000A automatic block system security and provides a reference to safety assessment of other railway signal and electromagnetic interference shielding.
