Intelligent monitoring and maintenance system for 25-cycle phase-sensitive track circuit

The invention discloses an intelligent monitoring and maintenance system for a 25-cycle phase-sensitive track circuit. The system is characterized in that the intelligent monitoring and maintenance system for the 25-cycle phase-sensitive track circuit is composed of an outdoor acquisition system and an indoor monitoring and analysis system. The outdoor acquisition system is composed of an outdoor acquisition box and a steel cable current acquisition mutual inductor. The indoor analysis system is composed of an indoor monitoring extension set and an analyzer. According to the invention, indoor and outdoor equipment, transmission channels and various influence factors of the 25-cycle phase-sensitive track circuit are monitored, and collected data are used as a basis for comprehensive analysis of various performance indexes and application states of track circuit equipment; functions of track circuit equipment state early warning, equipment fault alarm, fault positioning, analysis of various factors influencing
