Abstract

The invention is suitable for the technical field of rail transit operation and maintenance, and provides a broken rail detection method and device, and the method comprises the steps: obtaining the first position relation information of a current detection point and a broken rail position on a rail circuit; obtaining second position relation information of a previous detection point on the trackcircuit and the broken track position; and when the first position relation information is different from the second position relation information, marking a road section between the current detectionpoint and the previous detection point as a broken rail fault road section. According to the broken rail detection method and device provided by the embodiment of the invention, the broken rail position can be determined between two adjacent detection points by identifying the position of the detection point on the rail circuit relative to the broken rail position. Because the moving step lengthof the detection point can be freely set, the broken rail detection method provided by the embodiment of the invention can determine the broken rail position in a section of short distance, and can realize accurate positioning of the broken rail position.

Description

technical field [0001] The invention belongs to the technical field of rail transit operation and maintenance, and in particular relates to a method and device for detecting a broken rail. Background technique [0002] The main purpose of the track circuit is to detect whether the track section is occupied by a train, and at the same time it has the auxiliary function of track breakage detection. For example, the automatic blocking system composed of ZPW non-insulated frequency-shifting track circuit uses the resonance principle of the circuit, and uses the circuit characteristics to divide the entire interval and the super-long seamless line across the interval into many blocking intervals one by one. The signal state in the section can also detect in real time which blockage section the broken rail occurs in. Usually the length of the blocked section of the track circuit is more than 1 km. After identifying the blocked section with a broken rail, it is necessary to furthe...
