列车运行控制系统仿真故障注入方法研究

摘要

T he fault injection test method plays an important role in locating and remedying system design de-fects ,and it has been paid more and more attention in simulation of train control system (TCS) in recent years . In this paper , comprehensively surveying the current situations of fault injection researches at home and abroad and directing against the train control system , the way to build the TCS fault injection simulation platform based on HLA was studied ,typical fault injection case tests for the key equipment(interlocking and RBC) of the target simulation system were conducted with the simulation-based fault injection method , the speed-dis-tance curves in typical scenarios were compared and the effectiveness of the fault injection method was ana-lyzed . The research results show that fault injection simulation facilitates effective evaluation of the reliability of the train control system and so helps to improve the safety of the train control system .%故障注入测试方法对于系统设计缺陷的发现与补救具有重要意义，近年来故障注入在列车运行控制系统的仿真测试领域开始得到越来越多的关注。本文在国内外故障注入研究现状的基础上，针对列车运行控制系统，研究了基于HLA的列控系统故障注入仿真平台的构建方法，利用基于仿真的故障注入方法对目标仿真系统进行关键设备（联锁、RBC等）典型故障注入案例的测试，对典型场景下的速度-距离曲线进行分析比较，并总结分析了该方法的有效性。结果表明该故障注入仿真可以有效地对列控系统做出可靠性评估分析，提高系统安全性能。
