In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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.
The following describes, with reference to fig. 1, an interworking Train foldback processing method of the present invention, where an ATS (Automatic Train Protection) subsystem applied in a CBTC system includes: step 101, when a train is positioned in a parking area, determining whether to perform a turn-back operation on the train;

Optionally, it is determined whether the train is located in a parking area according to the current position of the train. The parking areas of different types of trains are different, and the method for confirming whether the train is subjected to the return operation is different. The present embodiment does not specifically limit the parking area and the method of determining whether to perform a folding back operation on the train.
When the train is not in the parking area, the ATS subsystem sends a no-return instruction to the ATP subsystem. After the train is stopped stably, the ATP subsystem does not display the turn-back prompt, and a train driver cannot perform turn-back operation.
And step 102, if the train is determined to be subjected to the retracing operation, sending a retracing instruction corresponding to the retracing operation to an ATP subsystem in the CBTC system, so that after the train is stably stopped in the parking area by the ATP subsystem, if the parking area has a retracing attribute corresponding to the retracing instruction, displaying a retracing prompt corresponding to the retracing instruction.
And when the ATS subsystem determines to perform the turn-back operation on the train, sending a turn-back command corresponding to the turn-back operation to the ATP subsystem. When the communication between the ATS subsystem and the ATP subsystem is normal, the ATP subsystem can receive a foldback instruction sent by the ATS subsystem.
After the train is stably stopped in the parking area, the ATP subsystem inquires whether the parking area where the train is located has the turn-back attribute corresponding to the turn-back instruction. Only when the parking area where the train is located has the turn-back attribute corresponding to the turn-back instruction, displaying a turn-back prompt corresponding to the turn-back instruction so that a train driver can perform turn-back operation according to the turn-back prompt; otherwise, the foldback prompt corresponding to the foldback instruction is not displayed.
For example, when the ATS subsystem determines to perform a post-station return on the train, the return instruction sent by the ATS subsystem to the ATP subsystem is a post-station return instruction. And after the train is stably stopped in the parking area, the ATP subsystem searches whether the parking area has the unmanned retracing departure attribute, if so, an unmanned retracing prompt is displayed, and the train driver performs unmanned retracing operation according to the prompt.
In the embodiment, when a train is positioned in a parking area, whether the train is subjected to a turn-back operation is determined through an ATS subsystem in a CBTC (communication based train control) system, so that an unexpected turn-back operation is avoided; and sending a turn-back instruction to an ATP subsystem in the CBTC system according to the determination result, judging whether the parking area meets the condition of turn-back operation or not by the ATP subsystem in the CBTC system, displaying a turn-back prompt according to the judgment result, and being suitable for various manufacturer lines to realize interconnection and intercommunication of the turn-back function of the CBTC system.

when the train is a planned train, the parking area is a platform. The ATS subsystem judges whether the maximum safe front end of the train is positioned at the platform. If the maximum safe front end of the train is positioned at the platform, the train is positioned in the parking area.
And if the maximum safe front end of the train is not positioned at the platform, the ATS subsystem sends a non-return instruction to the ATP subsystem.
Determining whether to perform a turn-back operation on the train according to the operation plan of the train; the foldback operation includes a pre-station foldback operation and a post-station foldback operation.
Alternatively, the planned train has an operation plan according to which the turning back operation on the train is determined when the maximum safe front end of the train is located at the station.
And if the train does not enter the station back return rail after the end change at the station in the operation plan, determining to perform station front return operation on the train, and sending a station front return instruction to the ATP subsystem. After the train stops stably at the platform, if the ATP subsystem finds that the platform where the train is located has the pre-station turn-back attribute, a turn-back prompt is displayed, and the train driver performs turn-back operation according to the turn-back prompt.
If the train needs to enter the station and return the rail in the operation plan, and the train moves to the opposite side of the platform after the end of the station return rail is changed, the station return operation of the train after the station is determined, and a station return instruction is sent to the ATP subsystem. After the train stops stably at the platform, if the ATP subsystem finds that the platform where the train is located has the unmanned retracing departure attribute, an unmanned retracing prompt is displayed, and a train driver performs unmanned retracing operation according to the unmanned retracing prompt.
On the basis of the foregoing embodiment, in this embodiment, after the sending a foldback instruction corresponding to the foldback operation to an ATP subsystem in the CBTC system, the method further includes: and under the condition that the turn-back operation is the post-station turn-back operation, when the train moves to a post-station turn-back rail of the platform, sending a turn-back instruction corresponding to the post-station turn-back operation to the ATP subsystem again so that the ATP subsystem can display a turn-back prompt corresponding to the post-station turn-back rail if the train is not in an unmanned turn-back flow after the train is stably stopped at the post-station turn-back rail.
And the ATS subsystem sends a back turn-back instruction to the ATP subsystem, after the train stops stably at the platform, if the ATP subsystem finds that the platform where the train is located does not have the unmanned turn-back departure attribute, the unmanned turn-back prompt is not displayed, a train driver cannot carry out unmanned turn-back operation on the train, and the train is continuously driven to run to the station back turn-back rail of the platform.
And when the maximum safe front end of the train is positioned at the back of the station and the rail is turned back, the ATS subsystem sends a back turn-back instruction to the ATP subsystem again. After the train is stopped stably on the return rail behind the station, the train is not in an unmanned return flow, namely the train is not in the unmanned return flow, a manned return prompt is displayed, and a train driver carries out manned return operation according to the manned return prompt; and if the ATP subsystem displays the unmanned return prompt, namely the train is in the unmanned return flow, the manned return prompt is not displayed.
1G to 6G in fig. 2 denote track sections, X1 to X5 denote down signals, and S1 to S5 denote up signals. As shown in fig. 2, for example, the current train is a planned train, and the ATS subsystem and the ATP subsystem communicate normally. The end point of the train operation plan is 4G, and the train operation direction is downlink, namely the train operates from 1G to 2G. And when the maximum safe front end of the train enters 3G, the ATS subsystem judges that the train needs to carry out post-station turn-back, and sends a post-turn-back instruction to the ATP subsystem. And when the train stops stably at the platform 3G, the ATP subsystem judges that the platform does not have the unmanned retracing departure attribute and does not display the unmanned retracing prompt. The train moves forwards, and when the maximum safe front end of the train turns back the rail 4G behind the station, the ATS subsystem sends a backward turn-back instruction to the ATP subsystem. And after the train is stopped stably on the back turn-back rail 4G, the ATP subsystem judges that the train is not in an unmanned turn-back flow, a turn-back prompting with a person is displayed, and a train driver performs turn-back operation with the person according to the prompting.
For example, the train is a planned train, and the ATS subsystem and the ATP subsystem are normally communicated. When the maximum safety front end of the train enters 3G, the ATS subsystem judges that the train needs to turn back after the train is placed, and sends a back turn-back instruction to the ATP subsystem. When the train stops stably at the platform 3G, the ATP subsystem judges that the platform has the unmanned retracing departure attribute, an unmanned retracing prompt is displayed, after the train driver performs unmanned retracing operation according to the prompt, the train enters an unmanned retracing process, and the ATP displays an unmanned retracing sign. And in the whole unmanned turn-back process, the unmanned turn-back mark is displayed and no longer shows the prompting of turning back people, namely, the ATP does not show the prompting of turning back people after the 4G of the turn-back rail of the train stops stably, and the train driver can not continue to carry out the operation of turning back people.
On the basis of the above embodiments, in this embodiment, the train is a first yard train, and the parking area includes a platform and a post-station return rail of the platform;
accordingly, the determining whether to perform a retracing operation on the train when the train is located in the parking area includes: if the maximum safe front end of the train is positioned on the platform or the back turning rail, the train is known to be positioned in the parking area;
and judging whether the train is positioned on the platform or the post-station return rail or not according to the position of the maximum safe front end of the train and the position of the post-platform return rail or the post-station return rail.
If the platform or the post-station return rail is the destination of the train, determining to perform return operation on the train; the foldback operation is a default operation;
since the head yard train has no operational plan, the destination of the train is known. Therefore, the ATS subsystem judges whether the platform where the head yard vehicle is located or the back-end return rail is the destination of the train, if so, the return operation of the train is determined, and the return instruction sent to the ATP subsystem is a default value. The default value of the foldback instruction is configured in advance.
After the train stops stably at the station or the back turn-back rail, the ATP subsystem judges whether the back turn-back rail at the station or the back of the station has the turn-back attribute under the condition that the turn-back instruction is a default value, if so, a manned turn-back prompt or an unmanned turn-back prompt corresponding to the turn-back attribute is displayed, and a train driver carries out manned turn-back operation or unmanned turn-back operation according to the prompt.
As shown in fig. 2, for example, the current train is the first train, and the ATS subsystem and the ATP subsystem normally communicate. The destination of the train is 2G, and the train running direction is descending, namely the train runs from 1G to 2G. When the maximum safety front end of the train enters 2G, the ATS subsystem judges that the current station of the train is the same as the destination, sends a turn-back instruction to the ATP subsystem as a default value, and the ATP subsystem judges that the area has a turn-back attribute and does not have an unmanned turn-back departure attribute after the train is stopped, displays a turn-back prompt of a person, and a train driver performs turn-back operation of the person according to the prompt.
If the platform or post-station return rail is not the destination of the train, judging whether the direction from the platform or post-station return rail to the destination is consistent with the running direction of the train or not;
if the train is inconsistent with the train turning-back operation, the train turning-back operation is determined; the foldback operation is a pre-station foldback operation;
and after the train is stopped stably, the ATP subsystem judges whether the station or the post-station return rail has a return attribute, if so, a person return prompt is displayed, and the train driver performs the person return operation according to the person return prompt.
If the destination is consistent with the destination, judging whether the platform or the post-station return track is adjacent to the destination;
if the train is adjacent to the train, determining to perform the default operation on the train;
and the return instruction sent by the ATS subsystem to the ATP subsystem is a default value. And after the train is stopped stably, the ATP subsystem judges whether the platform or the back turn-back rail has the unmanned turn-back departure attribute, if so, the unmanned turn-back prompt is displayed, and otherwise, the unmanned turn-back prompt is not displayed. The train driver can carry out unmanned turn-back operation according to the unmanned turn-back prompt.
And if not, determining that the train is not subjected to the turn-back operation.
And the ATS subsystem sends a no-return instruction to the ATP subsystem, a return prompt is not displayed after the train is stopped, and a train driver cannot perform a return operation.
When the maximum safe front end of the train is not at the platform and the return rail, the ATS subsystem sends a no-return instruction to the ATP subsystem, the ATP subsystem does not display a return prompt after the train is stopped, and a train driver cannot perform a return operation.
As shown in fig. 2, for example, the current train is a top train, the ATS subsystem and the ATP subsystem communicate normally, the destination of the current train is 4G, and the train operation direction is downlink, that is, the train operates from 1G to 2G. When the maximum safe front end of the train enters 2G, the ATS subsystem judges that the current station of the train is different from the destination, the running direction of the train is consistent with the direction from the station to the destination of the train, and the station is not adjacent to the destination of the train, and then the ATS subsystem sends a non-return instruction to the ATP subsystem. After the train stops stably, although the platform has the foldback attribute, the foldback prompt is not displayed, and the train driver cannot perform foldback operation.
On the basis of the above embodiment, the train in this embodiment is a manual vehicle, and the folding operation is a default operation.
The manual vehicle has no operation plan and the destination is unknown. When the manual vehicle runs to a parking area, the return instruction sent by the ATS subsystem to the ATP subsystem is a default value.
The ATP system judges whether to perform the retracing according to whether the parking area where the train is located has the retracing attribute. And if the foldback attribute exists, displaying a foldback prompt corresponding to the foldback attribute, otherwise, not displaying the foldback prompt. And the train driver performs the turning back operation with or without people according to the prompt.

Optionally, the ATS subsystem determines whether the train is located in a parking area based on the current location of the train. The parking areas of different types of trains are different, and the method for confirming whether the train is subjected to the return operation is different. The present embodiment does not specifically limit the parking area and the method of determining whether to perform a folding back operation on the train.
And when the train is in the parking area, the ATP subsystem receives a turn-back command corresponding to the determined train turn-back operation sent by the ATS subsystem.
And when the train is not in the parking area, the ATP subsystem receives a non-return instruction sent by the ATS subsystem. And after the train is stopped stably, the ATP subsystem does not display a turn-back prompt, and a train driver cannot perform turn-back operation.

And when the maximum safe front end of the train is positioned at the back of the station and the rail is turned back, the ATS subsystem sends a back turn-back instruction to the ATP subsystem again. After a train is stopped stably on a return rail after standing, if the train is not in an unmanned return flow, the situation that a driver does not carry out unmanned return operation on the train is shown, a person return prompt is displayed, and the train driver carries out person return operation according to the person return prompt; if the ATP subsystem displays an unmanned turn-back prompt, a driver can carry out unmanned turn-back operation on the train according to the unmanned turn-back prompt, and the train is in an unmanned turn-back flow.
