Abstract

The invention belongs to the field of rail transit automation, and in particular relates to a method and system for checking track circuit faults. The method for checking track circuit faults includes: providing power signals of different frequencies for adjacent two groups of track circuit sections; The power supply signal is transmitted through the track circuit section to generate a track circuit section signal; receiving and judging and processing the track circuit section signal, the judgment processing includes checking the frequency and amplitude of the received track circuit section signal, checking As a result, the fault condition of the track circuit can be discriminated. The method for checking track circuit faults of the present invention can overcome the defect of 25Hz phase-sensitive track circuit insulation damage protection, fully realize the insulation damage protection function, and further improve the safety of train operation; the method has a feedback inspection function, which enhances system maintainability. It is convenient to find problems early and locate faults.

Description

technical field [0001] The invention belongs to the field of rail transit automation, and in particular relates to a method and system for fault inspection of rail circuits. Background technique [0002] The track circuit is a circuit composed of rail lines and rail insulation, which is used to automatically and continuously detect whether this section of the line is occupied by rolling stock, and is also used to control signal devices or switch devices to ensure driving safety equipment. The entire track system road network is divided into many block sections according to appropriate distances. Each block section is separated by track insulation joints to form an independent track circuit. The starting point of each section is equipped with a signal machine. When the train enters the track section , the track circuit responds immediately, and conveys the message that there are already trains passing in this section and that other trains are prohibited from entering to the s...
