Train tail screening method and device and storage medium

Abstract

The invention provides a train tail screening method and device and a storage medium, and the method comprises the steps of determining whether a to-be-screened train meets a preset tail screening condition, and enabling the preset tail screening condition to be associated with at least one of train suspension, axle counting state collection delay and train-ground communication delay, wherein the train suspension and/or the train-ground communication delay are/is associated with a distance judgment condition included in the preset tail screening condition, and the train-ground communication delay is associated with a section idle judgment condition included in the preset tail screening condition; when the to-be-screened train meets the preset tail screening condition, determining that tail screening of the to-be-screened train is passed; and when the to-be-screened train does not meet the preset tail screening condition, determining that tail screening of the to-be-screened train is not passed. At least one of train suspension, axle counting state acquisition delay and train-ground communication delay is considered in the tail screening condition, so that the train tail screening result is more accurate, and train tail screening is more reasonable and safer.

Description

technical field [0001] The present application relates to the technical field of vehicle control, and more specifically relates to a method, device and storage medium for screening the rear of a train. Background technique [0002] The current train control technology generally screens the trains when the trains are running, and excludes hidden trains that may exist in the front and rear of the train. Screening generally includes train head screening and tail screening. Existing train tail screening methods only consider whether the distance from the screened train to the starting point of its physical section is less than the minimum train length for line screening and whether the adjacent physical section behind the physical section where the screened train tail is located is free. . [0003] The existing screening methods for the rear of the train have the following problems: the distance between the last axle counting detection board and the rear of the hidden train (c...

AI Technical Summary

Problems solved by technology

[0003] The existing screening methods for the rear of the train have the following problems: the distance between the last axle counting detection board and the rear of the hidden train (called "overhang") is not considered, so in the case of short communication delays, the rear of the train to be screened is hidden. The last axle counting detection board at the rear of the train has moved out of the rear adjacent physical section, but has not completely entered the physical section where the train to be screened is located. At this time, the rear adjacent physical section is idle, resulting in a successful tail screening misjudgment; The vehicle-to-ground communication delay is not considered, resulting in the Zone Controller (ZC) receiving the vehicle on-board controller (Vehicle On-Board Controller, VOBC) sending the rear position of the train to be screened to meet the distance from the physical section When the starting point is less than the minimum vehicle length of the line, this condition is not satisfied in fact; the delay in collecting the axle counting status is not considered, and there is a train entering the adjacent physical section at the rear, but the ZC receives the status of the physical section as idle, resulting in the adjacent The tail filter condition that the physical segment is free is misjudged successfully
