Detailed Description
The technical solution in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

At present, TB-T3027 defines that when a midway return shunting operation is performed in the same throat area, midway return unlocking can be realized by shunting the route under the following conditions:
a) when a train drives into a shunting route and partial sections of the route cannot be unlocked due to midway turning back, the partial sections should be automatically unlocked after the train is checked that the opened turning back signal machine drives into a control area of the signal machine and all the sections which are not unlocked are cleared;
b) when a train drives into a shunting route and all sections of the route cannot be unlocked due to midway turning-back operation, automatically unlocking after the train exits the route and the sections close to the route in sequence;
c) when the train enters the control area of the juxtaposition signal machine and all sections of the route cannot be unlocked due to midway retracing operation after the train enters the control area of the juxtaposition signal machine, the route is automatically unlocked after the train is checked that the train enters the control area of the signal machine according to the opened reverse juxtaposition signal machine and all the sections which are not unlocked are cleared.
When the train performs midway retracing unlocking on the route, the three situations need to be distinguished, and the processing process is relatively complex. In addition, when the train passes and fails in time to stop behind the semaphore of turning back, because the route of turning back begins to handle from the semaphore of turning back, if there is the switch between train and the semaphore of turning back, when the train turns back the operation according to open semaphore of turning back, because the switch between train and the semaphore of turning back is not by any route locking, then probably has the problem of separating the signal that the signal was seen at unblock switch, has the safe risk of crowded switch of train.
Based on the research, the embodiment of the application provides a shunting route midway turning back processing method, which can relieve the safety risk of train turnout squeezing when shunting midway returns and improve the train running safety.

And step 207, controlling the target train to turn back.
For example, the target train may be controlled to travel along a desired retrace route to retrace the target train to a desired destination.
In an embodiment, step 207 may include steps 2071 through 2072.
And 2071, determining an element to be unlocked according to the current position of the target train.
In an alternative embodiment, step 2071 may comprise: and determining a current unlocking element on the retracing route according to the current position of the target train.
Exemplarily, the determining a current unlocking element on the retracing route according to the current position of the target train includes: determining a first current position of the target train based on a positioning system of the target train; and determining a current unlocking element on the retracing route according to the first current position.

In the method for processing halfway retracing of a shunting route provided in this embodiment, in the process of pulling out the shunting route of a train, a specific processing procedure of the halfway retracing shunting operation is as follows: the method comprises the following steps that a train is handled to be drawn out and shunting to enter a route which takes the train as a main body, after relevant interlocking conditions are met, elements on the route path are locked, and a signal machine signal is opened, a target train runs on the drawn out shunting to enter the route, and the elements locked in the train running area on the route are unlocked along with the running of the train; after the train passes through the turn-back signal machine, the head of a target train before turn-back is taken as the starting point of the turn-back shunting route, and the turn-back shunting route taking the train as the main body is handled for the target train; the elements of the retracing shunting approach and the non-unlocking elements of the drawing shunting approach are overlapped at the position of the train body, and because the drawing shunting approach and the retracing shunting approach are handled by the same train, the overlapped part of the drawing shunting approach and the retracing shunting approach does not form an enemy, and the non-unlocking part of the drawing shunting approach does not influence the locking and opening permission signals of the retracing shunting approach; and the target train turns back according to the opened turn-back signal machine, and when the target train completely leaves the un-unlocked elements of the pull-out shunting route in the reverse direction, the un-unlocked elements of the pull-out shunting route can be completely unlocked.
Furthermore, when the target train turns back, the turn-back signal machine opens the permission signal after all turnouts on the traveling path in front of the target train are locked by the turn-back shunting route, so that the trouble-shooting risk caused by the movement of the turnouts in front of the target train and outside the turn-back signal machine in the traveling process of the target train is avoided. Through the shunting route handled by taking the train as a main body, after the back-turning shunting route is handled, the train can select to go forward and finish to pull out the shunting route, and can also realize the midway back-turning shunting route, thereby realizing the midway back-turning function of the shunting operation of free advance and retreat of the target train.

The road can be recovered for use by unlocking the elements on the route path of the target train which is drawn out of the shunting route.
Alternatively, step 208 may be implemented as: the unlocking elements in the elements on the route path of the drawn shunting route can be unlocked when the target train turns back according to the opened turn-back signal machine and completely leaves the unlocking elements of the drawn shunting route in the reverse direction.
Alternatively, step 208 may be implemented as: the non-unlocked elements of the shunting route can be unlocked when the target train completely passes over the turn-back signal machine.
Alternatively, step 208 may be implemented as: the unlocking elements in the elements on the route path of the shunting route are unlocked when the target train turns back according to the opened turn-back signal machine and completely leaves the unlocking elements of the shunting route in the reverse direction and completely crosses the turn-back signal machine.
For example, it may be determined that the target train completely passes over the folding signal when all elements of the outward area of the folding signal are unlocked.
For example, it may be determined from the precise location of the target train whether the target train has completely crossed the back-up signal.
For example, when all the sections in the area outside the turn-back signal on the turn-back shunting route are cleared, it is determined that the target train completely passes over the turn-back signal.
In this embodiment, before performing step 208, the method may further include: and judging whether the target train completely leaves an unlocked element of the pull-out shunting route in the reverse direction.
In one embodiment, when the occupancy clear sequence of the section unlocks an element on a train driving area on the retracing shunting route, so that the non-unlocked element of the retracing shunting route and the non-unlocked element of the pull-out shunting route are not overlapped, the target train is determined to completely leave the non-unlocked element of the pull-out shunting route in the reverse direction.
In one embodiment, a determination may be made as to whether the target train has completely left the unlocked element of the pull shunting route in a reverse direction based on the precise location of the target train.
In one embodiment, when the occupied clear sequence of the sections unlocks elements on the train driving area on the turn-back shunting route, so that the non-unlocked elements of the turn-back shunting route and the non-unlocked elements of the pull-out shunting route are not overlapped, and the sections of the non-unlocked elements of the pull-out shunting route are all cleared, it is determined that the train completely leaves the non-unlocked elements of the pull-out shunting route in the reverse direction.
In another embodiment, unlocking elements on a train driving area on the retracing route according to the accurate position of the train or the occupied clearing sequence of the section, so that the non-unlocked elements of the retracing route and the non-unlocked elements of the pull-out shunting route are not overlapped, and judging that the train completely leaves the non-unlocked elements of the pull-out shunting route in the reverse direction when all sections of the non-unlocked elements of the pull-out shunting route are cleared.
The shunting route midway turning-back processing method provided by the embodiment can realize turning-back in the shunting operation midway realized by adopting the shunting route mainly comprising the train, and the running processing process of the target train of the shunting route midway turning-back processing method provided by the embodiment of the application can have the following characteristics: the shunting approach and the shunting return of the target train can be converted into a method only involving two shunting approaches, and the shunting approach and the returning shunting approach are drawn out; the pull-out shunting approach and the turn-back shunting approach are shunting approaches taking trains as main bodies; the elements of the turning-back shunting route and the pulling-out shunting route which are not unlocked of the same target train are overlapped at the position of a train body; after the target vehicle turns back, elements which are not unlocked in pulling out the shunting route do not influence the handling and opening signals of the turning-back shunting route; after the signal of the back-turning shunting route transaction is opened, the areas on the forward and back-turning paths of the train are in a locking state, and the target train can move forward and back, so that the target train can move more flexibly.
