面向高速综合检测列车的应答器关键数据检测方法

Testing Method of Calise Critical Data for High-speed Comprehensive Inspection Train

应答器作为CTCS-2/3级列控系统的关键基础设备,其用户报文数据必须与现场列控数据准确对应。目前主要依靠人工及车载设备动态试验核对,工作量大且无法保证报文信息的准确性。为此提出了一种面向高速综合检测列车的应答器关键数据检测方法。首先通过KMP模式匹配算法实现现场列控数据的自动导入;其次利用深度路径搜索算法对应答器关键数据进行搜索,并和应答器用户信息进行对比,给出对比结果和报警日志;最后通过在海南西环线进行现场试验,验证可靠性,为高速铁路应答器报文检测研究及工程实践提供了有效的技术支持。

As a critical fundamental equipment of the CTCS-2/3train control system,the balise must keep its user data be exactly consistent with local train control data.At present,the check of balise user data can be implemented manually and via dynamic test of on-board equipment,which leads to heavy workload and difficulty in ensuring the accuracy of balise data.Therefore,one detection method of balise critical data based on high-speed comprehensive inspection train is proposed to solve the problem.Firstly,local train control data are automatically imported via the KMP Pattern Matching Algorithm.Secondly,all critical information of balise in local train control data are searched by the Depth Path Search Algorithm（DPSA）.In addition,all the searched critical data are compared with the user data of balise and the comparison results and warning logs are provided.Lastly,related tests are accomplished on all the balises in Hainan West Railway line.The test results verified the reliability of the detection method,which provides effective support for the research and engineering practice of balise detection in high-speed railway.
