Description

Train handover method suitable for resource access to interlocking access

Technical Field

The invention belongs to the technical field of rail transit, and particularly relates to a train handover method suitable for resource access to an interlocking access.

Background

The vehicle-vehicle communication CBTC area adopts a resource management mode to realize route management, and at the joint of non-CBTC areas such as non-automatic vehicle sections, the prior art adopts an OBC vehicle-mounted route resource management mode to manage locking and unlocking of a route of the entering section. Namely, after the OBC resource is reserved, entrance route locking is finished, manual entrance route handling is carried out, vehicle section interlocking entrance route locking is finished, after a train completely enters a switching rail, a driver confirms the degradation RM, and sends a logout response to the ground OC, and the driver disconnects a link with the OC after the logout response is received. The unlocking of the access in the process is divided into two parts: before the train-ground communication is disconnected, automatically releasing the rail switching resources of a train tail clearing part; and after the vehicle-ground communication is disconnected, starting a resource recovery process to recover resources so as to unlock the access.

When the train leaves the section, in order to prevent the access from conflicting, the interlocked exit access resources transacted to the section before the switching track belong to OC, and the access and exit access of the train transacted after the switching track is positioned have overlapping parts, and the resources of the overlapping parts have conflicts.

When the entry route unlocking node in the prior art recovers resources after the train-ground communication is disconnected, the resource recovery is delayed for a long time due to the requirement of driving safety, and the train entry efficiency is influenced. The resource conflict problem of the out-of-range route can cause the time of the out-of-range train entering the CBTC mode to be influenced after the OBC train enters the route handling position to be pushed.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

First, the technical terms appearing in the present invention are explained as follows:

CBTC: train automatic control system based on communication

And (3) OBC: vehicle-mounted controller

OC: target controller

RM: limiting manual driving modes

The invention adopts a resource management mode to realize the locking and unlocking of the switching track-in section access. And an OBC train route type is adopted, special resource processing and teleseme inspection setting of a transition rail area are overlapped, the transition from a resource management route to an interlocking logic route is realized together, and the train can be enabled to stably and efficiently exit from the CBTC area. And (3) locking the out-of-section route by adopting a non-resource reserved interlocking route, and handling the overlapped main train route by using the resource route to ensure the normal CBTC mode out-of-section of the train.

A train handover method suitable for resource access to interlocking access comprises the following specific technical scheme:

entry route locking and unlocking

As shown in fig. 1, after receiving a train route setting command, the OBC applies for resource reservation if checking that a section signal machine is not checked, completes the locking of the entering section route, and calculates a mobile authorization setting end point as the entering section route end point. Manually handling the vehicle section approach, and opening the vehicle section entrance signal machine after the approach is locked.

And after the train completely drives into the switching track in a CBTC mode, prompting a driver to confirm that degradation is RM, releasing all resources in an access road after the driver confirms, requesting logout to the OC after the resources are completely released, and disconnecting the OC after receiving a logout response of the OC to finish the degradation of the train and manually protecting the train from driving into a train section by using the RM.

The train still runs on the switching track when releasing all resources, and if the switching track section has a turnout, the use of the turnout occupation lock can protect the driving safety.

Train smoothly exits CBTC area

And after the OBC and the OC are disconnected, the OC is converted into a non-communication train for tracking according to the axle counting occupation. The system will secure the train in a non-communicative manner. In order to avoid the influence of degraded non-communication trains on subsequent tracking trains and ensure that two trains of CBTC trains can smoothly exit a CBTC area in a tight tracking mode, the MAL calculation increases capacity limit calculation, namely a section before a switching track and a section of the switching track are used as capacity limit areas, only one train is allowed to exist in the capacity limit areas, and the MAL withdrawal of a rear train caused by the degradation of the front train is prevented. After capacity limitation is adopted, the rear vehicle is allowed to drive into a section before the switching rail after the front vehicle completely drives into the vehicle section, and the rear vehicle can also normally exit in a CBTC mode.

Adversary protection of inbound route

After the OBC locks and switches the rail train to enter the road, a signal machine at the entering section is set for checking, and the checking is sent to the vehicle section through the OC for the enemy check of the exiting section entering road of the non-automatic vehicle section.

In the entering process, the switching track adopts an OBC vehicle-mounted route resource management mode to handle entering routes, all resources in the routes are released firstly when a driver confirms degradation RM, and then the resources are released quickly in a mode of logout to OC, so that the entering efficiency of the rear vehicle is ensured; the rail turnout area is converted by occupying lock protection, the capacity limitation is increased by MAL calculation to ensure that the train smoothly exits the CBTC area, and the enemy entry protection is realized by the check of the entry signal machine.

Out of section treatment

As shown in fig. 2, when the train leaves the train, manually handling the interlocking route to the signal machine of the leaving section, after identifying that the route is the leaving section route including the switching track, the OC does not reserve the route resource, locks the leaving section route (including the check of the check state of the signal machine of the entering section) according to the interlocking logic, and sets the signal machine of the leaving section to have the check.

After the train is manually driven to the switching rail for positioning, the OBC receives a train route setting command, applies for resource reservation, completes route locking to the main line, and drives the main line in a CBTC mode after the head screen passes through. And after the train completely exits the clear section entrance, the exit section entrance is normally unlocked according to the interlocking logic.

According to the out-of-range processing, the OC does not reserve relevant resources of the interlocking out-of-range route, when the train is ensured to handle the train route after the positioning of the switching track, the OBC can normally possess the switching track resources, the normal connection of the train from the interlocking route to the resource route is ensured, and the normal CBTC mode out-of-range of the train is completed.

While the invention has been described with reference to specific embodiments, it will be understood by those skilled in the art that the invention is not limited thereto, and may be embodied in other forms without departing from the spirit or essential characteristics thereof. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
