Train screening method and system based on moving block

Abstract

The invention provides a train screening method and system based on moving block. The method includes: receiving the current position information of the train and the occupancy information of the axle counting section; obtaining the axle counting section where the front of the train is located and the next axle counting section ahead according to the current position information of the train and the occupancy information of the axle counting section. occupancy of the axle section; judging whether the occupancy of the axle counting section where the front of the car is located and the next axle counting section in front meets the manual pre-screening condition; Screening operation, and after receiving the confirmation completion information indicating that there is no train within a certain range in front of the train, calculating the driving permit for the train. The method and system proposed by the present invention allow the driver to visually observe whether there are other trains in front of the train when the train meets the manual pre-screening conditions, and manually assist the RBC to complete the function of the train pre-screening, thereby completing the train upgrade in advance and improving the upgrade efficiency of heavy-duty trains .

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train screening method and system based on moving block. Background technique [0002] Front-end screening of trains (referred to as "front-screening") is a precondition for the RBC on the ground to calculate the driving permit for the train to be upgraded. Through the front-end screening of the train, RBC confirms whether there is a hidden train in front of the train to be upgraded to ensure the operation of the train Safety. After the front-end screening of the train to be upgraded is successful, RBC starts to try to calculate the driving permit for the train. Therefore, it is particularly important for the train to complete the front-end screening, which is the prerequisite for the train to be upgraded normally to become a mobile block train. [0003] The process of the existing train front-end screening method is as follows: [0004] 1) According to the position inf...

AI Technical Summary

Problems solved by technology

Considering the communication delay, there will be cases where the train passes the axle counter in front but has not been upgraded, resulting in RBC being unable to calculate the driving permit for the train

[0008] In addition, if image 3 As shown, when the distance between the front of the train and the first signal in front is a visually visible distance, and the driver can visually confirm that there is no train occupied within this range, since the distance between the front of the train and the front axle counter is still greater than the distance that may appear on the line The shortest length of the train, although there is no car in front, but according to the above front-end screening process, it is not possible to calculate the driving permit for the train, and the train still needs to be driven according to the visual driving mode, which seriously affects the upgrade efficiency of heavy-duty trains
