高铁轨道电路异常闪红解决方案研讨

Study on the Solution to Flashing Red Light Strip in High-speed Railway Track Circuit

轨道电路异常闪红的故障对高铁运输秩序及动车组的运行安全影响很大。通过对轨道电路异常闪红故障现象和原因的深入分析,提出解决方案。采用CAN总线数据监测定位故障点,由TCC对轨道电路状态进行判断,具备较高的安全性、可靠性和可用性,为郑西高铁正在实施的降速和全路高铁列控中心软件的升级,奠定了良好的软件版本和安全基础。

The fault of abnormal flashing red light strip in track circuit can affect transportation order and the operation safety of electric multiple units on high-speed railway seriously.Through an in-depth analysis of the phenomena and causes of such failures,a solution has be proposed.By monitoring fixed position the faults via CAN bus data,the conditions of the track circuit can be judged by the TCC.It was demonstrated that this solution was of high security,reliability,and availability and laid a good basis for the upgrading of software version and the slowing-down of Zhengzhou-Xi＇an high-speed railway and whole-railway software update of the Train Control Centers.
