摘要 针对ATS系统具有容错性、冗余性和顺序相关性等特点及传统的可靠性分析方法不能满足其分析要求,提出了故障树分析法并将其应用于ATS的可靠性仿真分析中。采用了结合Faunet简化方法和DFLM算法的故障树简化策略,同时给出故障树的定性分析和定量计算的算法推导,并将此方法应用于北京地铁2号线ATS系统的可靠性研究中。实验结果表明,该方法能够有效地计算ATS系统的可靠性指标并得出相应的数据分析结果。 ATS system is characterized by fault tolerance, redundancy, sequential correlation and so on, but there is no traditional reliability analysis method that can accord with the requirement on the analysis of ATS system. To make up for this deficiency, the thesis introduced the fault tree analysis method in the field of the reliability simulation analysis of ATS system. Meanwhile, by means of the fault tree reduction strategy which combines the Faunet simplified method with the DFLM algorithm, the thesis carried out qualitative analysis and quantitative calculation about the fault tree, and utilized the method into the reliability research of ATS system of Beijing Metro line 2. The experimental results show that with this method, the reliability indicators of ATS system can effectively be calculated and the corresponding results of data analysis can be obtained.
