Research on Algorithm of Track Circuit Occupation in CTCS-3 Simulation Platform

CTCS-3级列控系统仿真测试平台需要仿真轨道电路的占用,以实现列车的占用检查,为RBC计算行车许可和完成轨道电路编码提供基础条件。提出了一种精确实现站内轨道电路仿真占用查找的算法。通过将信号机作为参考原点,由数据库定位信号机,从与仿真联锁设备的通信中获取列车进路信息,将列车里程根据列车行驶方向进行累加或累减的变换,参考原点不停变换来查找轨道电路,并通过统一"进路"把站内轨道电路查找和区间轨道电路查找统一起来。该算法减小了仿真轨道电路的复杂性,为CTCS-3级列控系统仿真测试平台的搭建奠定了基础。

The platform of the CTCS-3 simulation testing need simulate the occupancy of track circuit in order to check the occupied section and the whole train so as to provide the basis conditions for other simulation equipment to calculate movement authority and to make track circuit code.Therefore,an algorithm is given to precisely look up the occupied track circuits within station in a simulation test,which takes the signal as a reference starting point and locate the signals through the database,gets the route information through the simulation interlock equipment and pluses and minuses the train＇s kilometers based on the direction of the train to find the occupied track circuit sections.The algorithm reduces the complexity of the simulation track circuit and lays the foundation for the CTCS-3 testing and simulation platform.
