The invention provides a 25Hz phase-sensitive track circuit monitoring method. The method comprises the following steps: acquiring track side and local side voltage signals of indoor receiving equipment of a 25Hz phase-sensitive track circuit; demodulating the rail side voltage signal and the local side voltage signal of the indoor receiving equipment to obtain an indoor signal; collecting current signals in cables of a power transmitting end and a power receiving end in the 25Hz phase-sensitive track section; performing demodulation processing on current signals in cables of a power transmitting end and a power receiving end in the track section to obtain outdoor signals; and outputting a monitoring result according to the indoor signal and the outdoor signal. According to the monitoring method provided by the invention, the whole 25Hz phase-sensitive track circuit can be monitored by monitoring the related parameters of the indoor and outdoor tracks. When the track circuit goes wrong, field personnel can quickly find and deal with the problems, and the railway driving safety is effectively guaranteed.

    本发明提出了一种25Hz相敏轨道电路监测方法,所述方法包括:采集25Hz相敏轨道电路室内接收设备的轨道侧和局部侧电压信号;对所述室内接收设备的轨道侧和局部侧电压信号进行解调处理获得室内信号;采集25Hz相敏轨道区段内送电端和受电端的电缆中的电流信号;对所述轨道区段内送电端和受电端的电缆中的电流信号进行解调处理获得室外信号;根据所述室内信号和室外信号输出监测结果。本发明所提出的监测方法通过对室内外轨道相关参数进行监测,能够实现对全路25Hz相敏轨道电路进行监测。当轨道电路出现问题时,现场人员可快速发现与处理,有效保证铁路行车安全。
