摘要
针对目前列控系统设计和开发过程中共因失效不易识别和评估问题,在分析列控系统失效特征基础上,通过建模和计算证明共因失效对于系统安全具有重要影响.采用系统安全理论,分析列控系统的共因失效影响因素,讨论共因失效的识别和筛选过程;基于列控系统3取2安全架构,计算包含共因失效的系统失效概率,指出由于缺乏历史统计数据造成共因失效定量计算的困难,最后提出控制列控系统共因失效的一般控制措施和方法.
Common cause failures（CCF） is not easy to be identified and evaluated in automatic train control （ATC） system design and development. The analysis of the failure characteristics of ATC system failures, system modelling and calculation demonstrated that CCF had a significant impact on the safety of the sys- tem. A CCF vulnerability factor was designed according to the system safety theory and the characteristics of the ATC system. Then, the process for CCF identification and screening was discussed. Based on the 2 out of 3 ATC safety architecture, the system failure probability which takes account of CCF was compu- ted. It is found out that it is difficult to quantitatively calculate the CCF due to the lack of historical CCF data. Finally, the general CCF control measures was discussed and summarized.
