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 , in the first occupancy situation, the matching result is the coordinate point belonging to the track section named 3DG, so it is known that the railway train is under positive pressure on the 3DG section at this time; after obtaining the section occupied by the head of the train, Then calculate the coordinates of the rear of the vehicle, because the information of the vehicle length and running direction has been obtained from the shunting plan, figure 1 The locomotive shown is a "west head" operation, the rear of the locomotive is located on the right side of the locomotive, and the surveying and mapping sections are searched in sequence from the front of the locomotive to the right. Because the distance between each point of the standard coordinates is fixed by 1 meter, search for a locomotive length along the standard surveying and mapping line section. The distance is the coordinates of the rear of the vehicle; considering the factors of vehicle len...

Abstract

The invention discloses a method for detecting faulty track circuit shunting based on railway train positioning. The method uses the positioning data of the on-board satellite positioning device of the railway locomotive, the standard surveying and mapping line data and the train train length data to combine to judge the overall actual alignment of the train. The first occupancy condition of the track section, and the first occupancy condition is compared with the second occupancy condition of the section given by the railway interlocking system. When the first occupancy condition and the second occupancy condition are not instantaneously inconsistent, it is determined that a shunt occurs. Bad phenomenon, through the accurate judgment of the bad shunt phenomenon, so as to avoid the safety accident and the idle section caused by the inaccurate information of section occupancy and clearing due to the bad shunt.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a method for detecting faulty track circuit shunting based on railway train positioning. Background technique [0002] At present, there has always been a problem of poor track circuit shunt in the field of rail transportation. Poor track circuit shunt refers to the fact that the track circuit surface of the track circuit cannot be properly dropped when the train or the train occupies the track due to the influence of bad conductors. Signal interlock failure, commonly known as "unkillable", "lost car" or "red light belt" and other phenomena. In addition, in the process of repeatedly marshalling, picking and hanging the trains at the end of the line, because the track circuit cannot distinguish the direction of the train, it will also cause phenomena such as "crush to death". In the event of poor track circuit shunting, train drivers and station dispatchers will mista...
