摘　　要：在系统分析的过程中,仿真测试方法目前广泛运用于系统分析中,其中故障注入方法是一种行之有效的测试验证手段。主要研究仿真故障注入方法及其在列车运行控制系统电磁兼容中的应用。首先介绍基于HLA的列车运行控制系统仿真平台。基于该仿真平台,提出基于Markov链的电磁兼容故障分析方法,同时建立电磁兼容故障案例数据库。结合列控系统中典型的电磁兼容故障,建立相应的故障测试案例,在列控仿真平台中进行测试并获得列控系统的安全性分析结果以及故障统计特性。实验结果表明,故障注入方法能够有效的对列控系统电磁兼容故障特性进行评估分析。Simulation based test method has been widely used in system analyses, in which fault injection is one of an effective tool. This paper studies the simulation fault injection method and its application in electromagnetic compatibility （EMC） of the train control system. It introduces a High Level Architecture （HLA） based train control system simulation platform, and puts forward Markov chain based EMC failure analysis method and the platform with EMC fault cases database. In view of typical EMC faults in the train control system, related fault testing cases are tested to obtain the safety analysis results and faults statistic features in the train control system simulation platform. The results show that simulation fault injection method can evaluate and analyze EMC faults of the train control system effectively.
