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.
