Method and system for detecting faults of high-speed railway signal system

The embodiment of the invention discloses a method and system for detecting the faults of a high-speed railway signal system. The method for detecting the faults of a high-speed railway signal system comprises steps of: determining testing nodes and tested nodes; instructing each testing node to send testing tasks to the tested nodes and to record testing responses fed back from the tested nodes; counting the testing responses received by the testing nodes and forming a fault characteristic matrix; and analyzing the fault characteristic matrix by using an artificial immune algorithm in order to position a current fault node in the high-speed railway signal system. 本发明实施例公开种高速铁路信号系统故障检测的方法和系统。高速铁路信号系统故障检测方法包括：确定多个测试节点和多个被测节点；命令每个所述测试节点分别向所述多个被测节点发送测试任务，并记录所述多个被测节点反馈的测试响应；统计所述多个测试节点接收到的测试响应并形成故障特征矩阵；通过人工免疫算法对所述故障特征矩阵进行分析，以定位当前高铁信号系统中的故障节点。
