摘要
针对轨道电路故障数据难以获得的问题,依据均匀传输线和电路二端口网络理论,在ATP-EMTP仿真软件中建立了ZPW-2000A轨道电路的室外轨道线路模型。对移频信号在轨道电路中的时域、频域传输特点进行了分析,提出将功率谱熵作为轨道电路故障特征量的方法,为实现轨道电路的在线故障诊断奠定了基础。
Since the fault data of the track circuit is difficult to be obtained,the outdoor track line model of the ZPW-2000A track circuit was established by using the ATP?EMTP simulation software based on the theories of uniform transmission line and two-port circuit network.The time?domain and frequency?domain transmission characteristics of the frequency shift signal in the track circuit are analyzed.The method of taking the power spectrum entropy as the fault feature quantity of the track circuit is proposed,which lays a foundation for realizing online fault diagnosis of the track circuit.
