Abstract

The invention provides a track circuit information acquisition method and system, and the method comprises the steps: converting a power signal of a power receiving end of a track circuit into a multi-path output signal based on a phase modulation lightning protection device, and collecting the multi-path output signal according to an acquisition unit disposed in each track board card; determining a target output signal collected by the main system track board card according to an arithmetic unit deployed in each system track board card; and determining an information acquisition result of the power receiving end of the track circuit according to the target output signal. The system executes the method. On the basis of the image recognition technology, the track circuit board is adopted to collect information of the track circuit, the track circuit board is completely isolated from the receiving end of the track circuit, work of the track circuit is not affected, the requirements for circuit faults and safety are met, and meanwhile automatic collection of the information of the track circuit is achieved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method and system for collecting rail circuit information. Background technique [0002] At present, in urban rail transit projects, parking lots / depots in some cities use 50HZ track circuit equipment for train position discrimination. [0003] The track circuit is divided into a sending end and a receiving end. Among them, the voltage, frequency and phase angle of the receiving end are important parameters for judging whether the working state of the track circuit is normal or not. At present, the state of track occupancy is realized by the track circuit receiver driving the track relay (GJ); the test of track voltage and phase angle is realized by the track test disk, and manual operation is required; and then the track voltage, phase angle and Frequency automatic monitoring. Since currently monitoring the working parameters (voltage, frequency, phase angle) of the tr...
