[0002] In the full-automatic operation system of urban rail transit, when a train needs to perform a reversal and end-changing operation, first, the ATS (Automatic Train Supervision) system needs to trigger the reversal route in advance, then send the command to the interlocking system (Computer Interlocking, CI), and then send the reversal route to the ZC (Zone Controller) system. The ZC system calculates the MA (Movement Authority) for the train and sends the type of MA as the reversal type to the train ATP (Automatic Train Protection). After the train runs to the destination of the MA, it performs a reversal and end-changing operation, and at the same time sends the information after end-changing to the ground. This method of reversal and end-changing must be based on a reversal route to perform the reversal and end-changing operation, which is relatively complex, and the train system has a dependence on data and scenarios.

[0005] Exemplarily, the train operation data includes the location information of the train and the train status information, and the train operation data includes the track information where the train is located and the operation plan information. Determining that the train needs to perform a reversing and end-changing operation based on the train operation data and the train operation data includes: determining that the train needs to perform a reversing and end-changing operation when the location information of the train, the track information where the train is located, the operation plan information, and the train status information meet a first preset condition; wherein, the first preset condition includes: the location information of the train is the end point of the train, the track information where the train is located has a reversing attribute, the operation plan information indicates that the train has a next operation plan, and the train status information indicates that the train has stopped stably.

[0025] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application and should not be construed as a limitation of the present application.

[0026] In some examples, such as Figure 1 the schematic diagram of the traditional reversing and crew change method shown. In the fully automatic operation system of urban rail transit, when a train needs to perform a reversing and crew change, first, the ATS (Automatic Train Supervision) system needs to trigger the reversing route in advance, then send the command to the interlocking system (Computer Interlocking, CI), and then send the reversing route to the ZC (Zone Controller) system. The ZC system calculates the MA (Movement Authority) for the train and sends the type of MA as the reversing type to the train ATP (Automatic Train Protection). After the train runs to the destination of the MA, it performs a reversing and crew change, and at the same time sends the information after the crew change to the ground. The ground area controller ZC calculates the MA information for the train based on the information after the crew change and the current reversing route. The ground ATS receives the direction of the train after the crew change and re-matches the plan according to the new train direction. This reversing and crew change method must be a reversing route to perform the reversing and crew change, which is relatively complex, and the train system is dependent on data and scenarios.

[0027] Based on this, the present application proposes a train reversing and crew change control method based on a fully automatic operation system, canceling the concept of a reversing route, mainly to solve the problem that the original technology must be a reversing route to perform a reversing and crew change, reducing the system's dependence on data and scenarios, and at the same time reducing the failure points.

[0028] Figure 2 is a flowchart of the control method for train reversing and crew change in an embodiment of the present application.

[0029] As Figure 2 shown, the control method for train reversing and crew change includes:

[0030] S201, after the train arrives at the destination, obtain the train running data and train operation data.

[0031] S202, when it is determined based on the train running data and train operation data that the train needs to perform a reversing and crew change operation, generate a train operation plan based on the train operation data.

[0032] S203, send the train operation plan to the train so that the train performs a crew change operation based on the train operation plan, where the crew change operation includes modifying the attribute information of the head and tail of the train to exchange the head and tail.

[0033] Exemplarily, the above control method for train turnaround and end-changing is applied to the Automatic Train Supervision (ATS) system. The ATS system communicates with the train. When the train reaches its destination, the ATS system acquires the train's running data and operation data. The ATS system can determine whether the train needs to perform a turnaround and end-changing operation based on the train's running data and operation data. When it is determined based on the train's running data and operation data that the train needs to perform a turnaround and end-changing operation, a train operation plan is generated based on the train's operation data and sent to the train, so that the train performs the end-changing operation based on the train operation plan. It can be understood that the ATS system can determine the location information of the current train based on the train's running data and operation data, and can reversely match the current plan and the head-code train. Herein, the head code can be understood as the destination, and the head-code train is a train with destination information. This method of turnaround and end-changing does not involve the turnaround route, nor does it involve the interaction between the ATS system and the interlocking system, and the end-changing method is simpler.

[0034] For the control method of train turnaround and end-changing in this application, during the process of line design and data production, there is no need to consider the turnaround route, which reduces the complexity of line design and the interlocking table, also reduces the interface fields between the interlocking and the LC system, reduces the fault points between devices, and reduces the basic data of the underlying system, improving the system operation efficiency.

[0035] As an example, determining that the train needs to perform a turnaround and end-changing operation based on the train's running data and operation data includes: determining that the train needs to perform a turnaround and end-changing operation when the location information of the train, the track information where the train is located, the operation plan information, and the train status information meet the first preset condition;

[0036] Wherein, the first preset condition includes: the location information of the train is the end of the train, the track information where the train is located has a turnaround attribute, the operation plan information indicates that the train has a next operation plan, and the train status information indicates that the train has stopped steadily.

[0037] Exemplarily, the train running data includes the location information of the train and the train status information, and the train operation data includes the track information where the train is located and the operation plan information. When the location information of the train is the end of the train, the track information where the train is located has a turnaround attribute, the operation plan information indicates that the train has a next operation plan, and the train status information indicates that the train has stopped steadily, it is determined that the train needs to perform a turnaround and end-changing operation.

[0038] Such as Figure 3As shown, the terminus of the train can be a station or a reversing area. The track information where the train is located has the reversing attribute. It can be understood that the track is pre-configured with the corresponding reversing attribute, and the track with the reversing attribute can be called the reversing track. It can be judged whether the track has the reversing attribute through Figure 3 the axle counter beside the track (i.e., the dot beside the track) as shown. It can be determined whether the train has a next operation plan through the operation diagram. When all the above four conditions are met, the Automatic Train Supervision (ATS) system can reversely match the next operation plan for the train and send the operation plan of the train to the currently operating train.

[0039] Exemplarily, as Figure 3 shown, when the CT train runs to the terminus of the current operation plan or a certain platform, the Automatic Train Supervision (ATS) system obtains the attribute of the track where the train is located in real time through the axle counter beside the track. For example, the track attribute on the platform side is pre-configured as the reversing attribute. The Automatic Train Supervision (ATS) system also obtains the operation plan information of the train in real time. If the operation plan information of the train indicates that the CT train has a next operation plan and the CT train has stopped stably (the CT train interacts with the Automatic Train Supervision (ATS) system and sends the operation status of the CT train to the Automatic Train Supervision (ATS) system), the Automatic Train Supervision (ATS) system reversely matches the next operation plan for the train.

[0040] As an example, the control method for train reversing and changing ends further includes: when at least one of the position information, track information, operation plan information, and train status information does not meet the first preset condition, receiving the train configuration plan, and generating a train operation plan according to the train configuration plan and the track information where the train is located; wherein, the train configuration plan includes at least one of the planned running direction of the train, the destination of the train, and the next stop of the train.

[0041] Exemplarily, when any one of the above four conditions is not met, for example, the position information where the train is located is not the terminus of the train, or the track information where the train is located does not have the reversing attribute, or the operation plan information indicates that the train has no next operation plan, or the train status information indicates that the train has not stopped stably, the Automatic Train Supervision (ATS) system will not automatically reversely match the next plan for the train. To maintain the normal operation of the train, the train configuration plan can be received to match a new operation plan for the train, such as manually setting the head code or matching the plan. The train configuration plan includes at least one of the planned running direction of the train, the destination of the train, and the next stop of the train.

[0042] As an example, generating a train operation plan according to the train configuration plan and the track information where the train is located includes:

[0043] When the track information where the train is located does not have the property of turning back, a train operation plan is generated according to the train configuration plan in the current train operation direction;

[0044] When the track information where the train is located has the property of turning back, first generate a train operation plan according to the train configuration plan in the current train operation direction. In the case where generating the train operation plan in the current train operation direction fails, then generate a train operation plan according to the train configuration plan in the direction opposite to the current train operation direction;

[0045] Among them, the failure to generate a train operation plan in the current train operation direction means that no operation line can be matched in the current train operation direction.

[0046] Exemplarily, the Automatic Train Supervision System (ATS) searches for and matches the train operation plan according to the plan configured in the system or the headcode destination. First, it judges whether the track information where the current train is parked has the condition of turning back. If it does not have the condition of turning back, then the ATS matches the input plan and headcode forward in the current train operation direction (searching in the original direction of the train), calculates the operation path, and sends the train plan and headcode to the train. If no headcode can be found in the original direction of the train, it means the matching fails, and the interface will prompt, for example, display the text information "The currently input plan or headcode cannot be matched, and no relevant plan and headcode are found" to remind relevant personnel.

[0047] Exemplarily, if the track information where the current train is parked has the condition of turning back, first match the plan or headcode in the train operation direction. If successful, generate a train operation plan in the current train operation direction. If the matching fails, then search for and match the plan or headcode in the reverse direction. If the reverse matching is successful, generate a train operation plan in the direction opposite to the current train operation direction. If the reverse matching fails, the interface will prompt text information such as "The currently input plan or headcode cannot be matched, and no relevant plan and headcode are found". It can be understood that when the track information where the train is located has the property of turning back, first generate a train operation plan in the current train operation direction. In the case where generating the train operation plan in the current train operation direction fails, then generate a train operation plan in the direction opposite to the current train operation direction.

[0048] As an example, the train performs an end-changing operation based on the train operation plan, including: performing the end-changing operation when the train operation plan, train status information, and track information meet the second preset condition; among them, the second preset condition includes: the track information where the train is located has the property of turning back, the train status information indicates that the train has stopped stably, the train operation plan indicates that the planned operation direction of the train is opposite to the current train operation direction, and the next stop can be determined according to the planned operation direction of the train.

[0049] Exemplarily, when the train receives the train operation plan issued by the ATS (the obtained operation plan may be forward or backward), it determines whether a reverse end change is required based on the train operation plan, train status information, and track information. When the track information where the train is located has the reverse attribute, the train status information indicates that the train has come to a complete stop, the train operation plan indicates that the planned running direction of the train is opposite to the current running direction of the train, and the next station can be determined based on the planned running direction of the train, the end change operation is executed.

[0050] Exemplarily, when the planned running direction of the train received by the train from the ATS is opposite to the current running direction of the train, the train has come to a complete stop on the reverse track, and the train can find the next station to run according to the running direction issued by the ATS, the end change operation can be performed. When one of the conditions is not met, the end change cannot be performed.

[0051] As an example, such as Figure 4 shown, the train includes the Automatic Train Protection module ATP. The Automatic Train Protection module ATP includes the head ATP and the tail ATP. Executing the reverse end change operation includes:

[0052] S401, controlling the train to output an emergency braking command to brake the train.

[0053] S402, controlling the head ATP to send an end change instruction to the tail ATP, and when the head ATP receives the confirmation information returned by the tail ATP, perform the reverse end change operation.

[0054] Exemplarily, the train includes the Automatic Train Protection module ATP. The Automatic Train Protection module ATP includes the head ATP and the tail ATP. It can be understood that one of the head ATP and the tail ATP is the control end. When the permission attributes of the two are exchanged, it is determined that the end change operation is to be performed. When the train ATP is in the process of reverse end change processing, control the train to output an emergency braking command to ensure the safety of the train. When the ATP control end (which can be understood as the ATP on the locomotive) collects that the emergency braking has been implemented, it sends reverse information such as its own position to the ATP opposite end (the ATP at the tail). At the same time, it receives the information from the ATP opposite end, that is, the head ATP receives the information from the tail ATP. It can be understood that the head ATP sends the end change instruction, and the tail ATP sends the confirmation information. After receiving the confirmation information from the opposite end, the ATP enters the state of completing the reverse end change, and the ATP opposite end is upgraded to the control end (at this time, the tail ATP is the control end). At this time, the ATP control end will recalculate the position information of the head and tail of the train, swap the positions of the head and tail before the end change, the position of the head before the end change becomes the position of the tail after the end change, and the position of the tail before the end change becomes the position information of the head after the end change. The running direction of the train is opposite to that before the end change.

[0055] As an example, the train further includes a line controller LC, which communicates with the train automatic protection module ATP. After the line controller LC identifies that the train automatic protection module ATP has completed the operation of reversing and changing the end, it controls the line controller LC to calculate the train movement authorization according to the position information of the ATP at the head and the ATP at the tail after the end change.

[0056] Exemplarily, after the train completes the end change, the ATP sends the running direction after the end change and the position information after the end change to the line controller LC. The line controller LC receives the position information and the train direction of the train ATP in real time. When the line controller LC identifies that the position and direction of the train have changed, it is considered that the train has performed the end change operation, and the MA calculation after the train end change needs to be processed.

[0057] Exemplarily, after the line controller LC identifies that the train has changed the end, it is necessary to continue to maintain the train movement authorization MA to ensure that after the train changes the end, it can still maintain the CBTC (Communication Based Train Control) level. CBTC is a continuous train automatic control system constructed by the train active positioning technology that does not rely on trackside train occupancy detection equipment, the continuous unified bidirectional data communication technology, and the on-vehicle and ground processors that can perform safety functions. It can be understood that the train needs to maintain the CBTC operation mode during normal operation. At this time, the line controller LC needs to process the MA calculation after the train end change. Among them, the end point of the MA is the axle counter point in front of the head of the train, the starting point of the MA is the tail of the train, the MA direction is the direction from the starting point of the MA to the end point, and the calculated MA information is sent to the train.

[0058] Figure 5 It is the flowchart of the automatic reversing and end changing of the operation system in an embodiment of the present application.

[0059] As Figure 5 shown, when the train runs to the reversing area (i.e., the reversing track), the train automatic monitoring system ATS determines whether to automatically match the reverse plan and the head code according to the train running data and the train operation data. If it is determined according to the train running data and the train operation data that the train needs to perform the reversing and end changing operation, the ATS automatically matches the reverse plan and the head code. When the matching of the reverse plan and the head code fails, it receives the manual matching plan and the head code, generates the train running plan, sends the train running plan to the train, the train performs the automatic end change according to the new running plan, the line controller LC calculates the movement authority MA information according to the information after the end change, and the train runs based on the new movement authority MA.

[0060] The control method for train reversing and end-changing in this application cancels the concept of reversing route. The train reversing and end-changing will not be restricted by whether the route is a reversing route, that is, during the process of line design and data production, there is no need to consider the reversing route. When the train reaches its destination, the ATS can automatically determine the current location information and can reversely match the current plan and the head code train. When the train receives the operation plan issued by the ATS, it judges whether it needs to reverse and change ends according to the train operation plan. The line controller LC receives the position information and the train direction of the train ATP in real time. When the LC identifies that the position and direction of the train have changed interchangeably, it is considered that the train has performed an end-changing operation, and it is necessary to process the MA calculation after the train end-changing.

[0061] This application also proposes a control method for train reversing and end-changing.

[0062] As an example, as Figure 6 shown, the control method for train reversing and end-changing includes:

[0063] S601, receiving the train operation plan, where the train operation plan is that after the train reaches the destination, the train automatic monitoring system ATS obtains the train running data and the train operation data. When it is determined that the train needs to perform a reversing and end-changing operation based on the train running data and the train operation data, the train operation plan is generated based on the train operation data and the train operation plan is sent to the train.

[0064] S602, performing an end-changing operation based on the train operation plan, where the end-changing operation includes modifying the attribute information of the head and the tail of the train to exchange the head and the tail.

[0065] Exemplarily, the above control method for train reversing and end-changing is applied to the train. The train communicates with the train automatic monitoring system ATS. The train automatic monitoring system ATS sends the train operation plan to the train, and the train performs an end-changing operation based on the train operation plan.

[0066] This application also proposes a control device for train reversing and end-changing.

[0067] As an example, as Figure 7 shown, the control device for train reversing and end-changing includes:

[0068] An acquisition module 701, configured to obtain train running data and train operation data after the train reaches the destination;

[0069] A generation module 702, configured to generate a train operation plan based on the train operation data when it is determined that the train needs to perform a reversing and end-changing operation based on the train running data and the train operation data;

[0070] The sending module 703 is configured to send the train operation plan to the train, so that the train performs a cab change operation based on the train operation plan, where the cab change operation includes swapping the front and rear ends of the train.

[0071] This application also proposes a train reversing and cab changing system.

[0072] As an example, the train reversing and cab changing system includes: an Automatic Train Supervision module (ATS), which is used to obtain train operation data and train operation data, and when it is determined based on the train operation data and train operation data that the train needs to perform a reversing and cab changing operation, generate a train operation plan based on the train operation data; an Automatic Train Protection module (ATP), which is used to perform a reversing and cab changing operation based on the train operation plan when receiving the train operation plan from the Automatic Train Supervision module (ATS); a Line Controller (LC), which is used to calculate the train movement authorization according to the position information of the ATP at the front end and the ATP at the rear end after the cab change after identifying that the Automatic Train Protection module (ATP) has completed the reversing and cab changing operation.

[0073] The train reversing and cab changing system of this application realizes the reversing and cab changing operation through the interaction between the Automatic Train Supervision module (ATS) and the train. It does not need to trigger the reversing approach in advance by the ATS and then send the command to the interlocking system like the traditional technology. The interlocking system then sends the reversing approach to the ZC, and the ZC system calculates the type of MA for the train as the reversing type. The train reversing and cab changing system of this application is simpler and more efficient, overcomes the disadvantage that the original technology must be a reversing approach to perform the reversing and cab changing, reduces the system's dependence on data and scenarios, and also reduces the failure points due to the simplicity and efficiency of the system.

[0074] This application also proposes a computer-readable storage medium.

[0075] In this embodiment, a computer program is stored on the computer-readable storage medium, and when the computer program is executed by a processor, the steps of the above-mentioned control method for train reversing and cab changing are realized.

[0077] The embodiment of this application provides an electronic device, including a memory and a processor. The memory stores a computer program, and when the processor executes the computer program, the above-mentioned control method for train reversing and cab changing is realized.
