摘　　要：自动闭塞线路通过轨道电路向列车传递低频码来反映前方空闲闭塞分区的数量,为列车运行提供行车指令,一旦轨道电路低频码错误将产生严重的安全风险。为此研究一种通过既有信号集中监测系统(CSM)实现轨道电路低频码序监督的方法。结合CSM系统的自采集数据、ZPW-2000接口数据、列控中心接口数据、联锁接口数据等,实现相邻区段(闭塞分区)低频码码序一致性分析、区段(闭塞分区)低频码与区段占用逻辑一致性分析,以及区段低频码与前方信号机显示逻辑一致性分析等。当出现不一致时,可以及时报警提醒。同时,针对一些特殊场景进行分析并提出对应规避措施。基于“仿真测试+现场跟踪”相结合的测试验证表明,该方法准确可靠,可避免误报和漏报的发生。The automatic block line transmits low-frequency codes to the train through the track circuit to indicate the number of unoccupied block zones ahead and provide train operation instructions.Once the low-frequency code in the track circuit is incorrect,it will cause serious safety risks.To this end,a method for implementing low-frequency code sequence supervision of track circuits through an existing signal centralized monitoring system(CSM)is studied.By combining the self-collected data of the CSM system,ZPW-2000 interface data,train control center interface data,interlocking interface data,etc.,the low-frequency code sequence consistency analysis of adjacent sections(block sections),the consistency between low-frequency code and occupancy logic analysis of sections(block sections),and the consistency between low-frequency code of sections and front signal display logic analysis are achieved.In case of inconsistency,timely alarm reminders are given.At the same time,some special scenarios encountered in the application process and corresponding avoidance measures is also discussed.Based on the combination of“simulation test+field tracking”,the test verification shows that the method is accurate and reliable to avoid producing false and missing reports.
