A vehicle-ground coordinated train path resource management and authorization method

Abstract

The present invention proposes a vehicle-ground coordinated train travel path resource management and authorization method, comprising the steps of: travel path resource information query, travel path resource information feedback, travel path calculation, travel path resource application, travel path resource management and authorization, and turnout Resource action, update travel path, travel path occupation and release. The invention makes full use of the communication technology to realize the acquisition of parameter information by the train and actively calculates its own traversable path, reduces the information transmission link, improves the autonomy of the train, and greatly reduces the construction difficulty and cost of ground equipment; Resource use, the extension range of the traversable path in the present invention only needs to consider the authorization of the two opposite turnout resources in front of the train, and no longer needs to be locked like the entire approach resource in the traditional signal system to extend the movement authorization. , improve the utilization rate of resources in the throat area and increase the throughput of the throat area.

Description

technical field [0001] The invention relates to the technical field of rail transit. Background technique [0002] The track is the basic equipment that provides running conditions for trains in the rail transit system. In order to ensure that multiple trains can run on the track line at the same time, the track area is divided into several fixed range areas for trains to use, which are called track sections. Among them, the track section can only be occupied by one train at the same time, and only when the train leaves the range of the track section can it be occupied by subsequent trains, especially for the section with fork, only when the train leaves the section with fork Only then can the switch be operated to change the running direction for the subsequent train. [0003] During the running of the train, the train needs to obtain the use permission of the track section in front to occupy it. The traditional CBTC authorizes the range of a continuous track section tha...

AI Technical Summary

Problems solved by technology

[0004] Considering that the resource authority allocation of the traditional CBTC system is calculated based on trackside equipment, the train lacks autonomy, and at the same time, a large number of information interaction behaviors cause hidden dangers in information communication, which is an unfavorable factor affecting driving safety; and the track section The granularity of the division is relatively large, which leads to the long time that the train occupies the track section, which reduces the utilization rate of the track section to a certain extent, especially in the throat area of ​​the station, it is necessary to lock a large number of track section resources in the station at the same time in the form of access Provide authorization for trains, causing other trains to be unable to use the relevant track sections during the time when the route is not unlocked, which affects the utilization of station resources and wastes the traffic capacity in the throat area
