Description

Train verification method, device, computer equipment and readable storage medium Technical Field The present application relates to the technical field of rail transit, and in particular, to a train verification method, a train verification device, a train verification computer readable storage medium and a train verification computer program product. Background Along with the development of rail transit, in order to ensure the running safety of the train and ensure that the front end and the tail end of the train are not hidden, the safety of the end of the train needs to be checked. In the conventional technology, for each train in the virtual marshalling, in a fixed range of the train, which is close to a section boundary in the axle counting section, the mobile blocking system determines the unoccupied train end of the end corresponding to the adjacent section as the safety check passing, and prolongs the mobile authorization terminal point in real time based on the safety state of the safety check passing in the running of the train, so that the train can run at a faster speed in a range before the mobile authorization terminal point. However, when the train is far from the zone boundary, if the safety verification fails due to the influence of the preceding train in the virtual consist, the safety verification cannot be performed again on the train, and the movement authorization end point of the train cannot be prolonged, so that the train can only perform driving in a visual mode (the highest running speed of 25 km/h) under the driving safety requirement. However, in the conventional technology at present, the safety verification cannot be performed again on the train which is far from the section boundary and fails in the safety verification based on the fixed range, resulting in poor running efficiency of the train.
