Abstract

The invention belongs to the field of rail transit automation, and particularly relates to a method and system applicable to track circuit fault inspection. The method for track circuit fault inspection comprises the steps of providing power signals of different frequencies for adjacent two sets of track circuit sections, transmitting the power signals through the track circuit sections to generate track circuit section signals, receiving the track circuit section signals and performing judgment and processing of the track circuit section signals. The judgment and processing comprise inspection of frequencies and amplitudes of the received track circuit section signals, and the inspection result can be used for judging a track circuit fault condition. The method for track circuit fault inspection can overcome the deficiencies of insulation damage protection of a 25 Hz phase sensitive track circuit, thereby comprehensively achieving the function of insulation damage protection and further improving the train running safety. The method has a feedback inspection function, thereby enhancing the maintainability of the system, and facilitating early finding of troubles and fault location.

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...
