Problems solved by technology

[0004] Among them, method 1) The cost of adding equipment and maintenance is expensive, and there is no cost advantage compared with manual safety confirmation, and the reliability and stability of adding induction equipment cannot be guaranteed, which may cause false detection and false detection, which will affect traffic efficiency ; Method 2) The indirect positioning method based on STP is not accurate, and does not solve the problem of turning back in the middle of shunting and positioning of complete trains

Embodiment 1

[0034] exist figure 1 Among them, in the first occupancy situation, the matching result is the coordinate point under the track section named 3DG, so it is known that the railway train is pressing on the 3DG section at this time; after obtaining the section occupied by the front, Then calculate the coordinates of the rear of the vehicle, because the vehicle length and running direction information have been obtained from the shunting plan, figure 1 The locomotive shown is the "west head" operation, the rear of the locomotive is located on the right side of the locomotive, and the surveying and mapping section is searched sequentially from the front of the locomotive to the right. Because the standard coordinates have a fixed difference of 1 meter between each point, search for a locomotive length along the standard surveying and mapping route section The distance is the coordinates of the rear of the vehicle; considering the vehicle length error and positioning error factors, ...

Abstract

The invention discloses a method for detecting poor shunting of a track circuit based on railway train positioning. The method comprises the steps: by utilizing positioning data of a locomotive-mounted satellite positioning device, standard surveying and mapping line data and train length data, judging a first actual occupation condition of the train set on the track section in a combined manner;comparing the first occupation condition with a second occupation condition of the section given by a railway interlocking system; and when the first occupation condition is not instantaneously inconsistent with the second occupation condition, determining that a bad shunting phenomenon occurs. Through accurate judgment of the bad shunting phenomenon, safety accidents and idle sections caused by inaccurate section occupation and clearing information due to bad shunting are avoided.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a detection method for a faulty branching of a rail circuit based on the positioning of railway trains. Background technique [0002] At present, in the field of rail transportation, there has always been a problem of bad track circuit shunting. Bad track circuit shunting means that the rail surface of the track circuit is affected by bad conductors, causing the train or the track relay that controls the track section to fail to fall normally when the train occupies the track, resulting in Signal interlock failure, commonly known as "undead", "lost car" or "red light belt" and other phenomena. In addition, in the process of repeated marshalling and unloading of trains at the end points of the line, the track circuit cannot distinguish the direction of the train, which will also cause "undead" and other phenomena. When there is a poor branching of the track circuit, t...
