The embodiment of the invention discloses a track circuit state monitoring system and method. The track circuit state monitoring system comprises: an outdoor equipment data acquisition system used foracquiring current information of each outdoor track circuit; a station machine which is used for receiving and uploading the current information of each outdoor track line; a data processing system which is used for receiving current information, uploaded by the station machine, of each outdoor track line and comparing the current information of each outdoor track line segment with a corresponding preset current threshold range, and carrying out current fault judgment, fault early warning or fault warning of the corresponding track line segment when the current information of each outdoor track line segment exceeds the corresponding preset current threshold range,. According to the embodiment of the invention, the current monitoring of each section of track line of the track circuit outdoor equipment is realized, the abnormity of the outdoor track line can be found as soon as possible, the fault point is determined, and maintainers are assisted in accurate and rapid maintenance.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of rail traffic monitoring, and in particular, to a system and method for monitoring the status of rail circuits. Background technique [0002] The track circuit is a circuit composed of rail lines and rail insulation, and is an important basic equipment for railway signals. The safety monitoring and maintenance of track circuit equipment is an important task in the railway department, and its performance directly affects the driving safety and transportation efficiency. [0003] The track circuit is mainly used to monitor the occupancy of the train and respond to the idle status of the line, providing a basis for opening signals, establishing access routes or forming blockages; at the same time, checking and supervising whether the rails on the track are intact. When the rails in a certain track circuit section break At the same time, the track relay will also release the armature...
