摘　　要：常规的地铁综合监控系统可靠性评估方法主要使用GOOSE MMS报文生成可靠性校验载体,易受监控系统运行状态影响,导致可靠性评估异常,因此需要基于快速BP算法设计一种全新的地铁综合监控可靠性评估方法。利用快速BP算法构建了可靠性评估模型,结合故障树确定了地铁综合监控系统失效概率,从而实现了地铁综合监控系统可靠性评估。实验结果表明,设计的地铁综合监控系统可靠性评估方法评估的不同故障失效率与实际故障失效率接近,证明其评估效果较好,具有准确性,有一定的应用价值。The conventional reliability evaluation methods for subway comprehensive monitoring systems mainly use GOOSE MMS messages to generate reliability verification carriers,which are easily affected by operating status of monitoring system,leading to abnormal reliability evaluation.Therefore,it is necessary to design a new subway comprehensive monitoring reliability evaluation method based on fast BP algorithm.In this paper,the reliability evaluation model is constructed by using fast BP algorithm,and the failure probability of the subway integrated monitoring system is determined by combining with the fault tree analysis,so as to realize reliability evaluation of subway integrated monitoring system.The experimental results show that the different failure rates evaluated by the designed reliability evaluation method are close to the actual failure rates,demonstrating satisfactory evaluation effect,certain accuracy and applicative potential of the designed method.
