| 摘 要： | 在长大隧道中,由于无缝长轨和整体道床的应用,使得传统轨道电路的使用受到限制,现在用计轴加轨道电缆取代轨道电路,原轨道电路的断轨检测功能消失.针对此情况给出了一种实时在线的断轨检测方法.推导出相应的轨道电路在调整态和断轨态下电流的函数关系式.通过对不同的道床电阻、轨道长度及在不同断轨位置的MATLAB仿真分析,证明这种方法能够准确判定断轨的范围.

| Abstract: | Owing to the application of continuous welded rail and integral roadbed in the long and large tunnels,the use of traditional track circuit is restricted. Now the track circuit is replaced by axis counter and rail cable, so the original broken rail detection function disappears. In view of above case, a real-time detection method for broken rail is presented. The current functions in the state of normal and broken rail are derived. The simulation with MATLAB in the different ballast resistance, length of the track and location of broken rail demonstrates a conclusion that this system can decide the scope of broken rail accurately. |
