Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit, in particular to a method and system for resource sharing management in a coupling or uncoupling area. BACKGROUND

[0002] In urban rail transit systems, to cope with tidal passenger flow, the flexible marshalling operation mode of train coupling (merging multiple trains into one train) and uncoupling (splitting one train into multiple trains) has become a key means to improve transportation efficiency. The Train Autonomous Control System (TACS) that implements this mode usually manages the running path with "resources" as the core and follows the basic principle of resource exclusivity, that is, the same line resource is only allowed to be used exclusively by one train at the same time, which is the basis for ensuring train operation safety.

[0003] However, the coupling and uncoupling operations themselves fundamentally conflict with the exclusivity principle of resources. In the coupling operation, the coupled train and the decoupled train must enter the same coupling area at the same time, resulting in the overlap of the safety body envelopes of the two trains in the area; in the uncoupling operation, the separated trains also need to coexist in the uncoupling area. If the exclusive principle is rigidly applied, such operations will not be able to be performed at all due to the inability to allocate resources.

[0004] Some explorations on resource sharing have appeared in the prior art. For example, a patent with publication number CN114275015B proposes a train control system and method based on resource management, which divides resources into "shared resources" and "exclusive resources" and manages them based on operation scenarios. However, this solution focuses more on solving the resource competition and deadlock prevention problem in general scenarios such as turnaround and tracking operation, and does not propose a complete and dedicated safety interaction process for the resource allocation safety problem caused by the overlap of train body envelopes in the specific operation of coupling and uncoupling.

[0005] Another patent with publication number CN120621461A focuses on using the TACS system to realize flexible marshalling, and its core innovation is to optimize the control strategy of the decoupled train, allowing it to switch control modes and move authorization without stopping at a stop point, thereby improving the efficiency of the coupling operation. However, this solution mainly solves the problem of train control efficiency, and its underlying still relies on a safe and reliable resource sharing management mechanism as a prerequisite. The specific implementation of this resource sharing mechanism, especially how to ensure the safety of the operation through multi-subsystem coordination and multiple safety checks, is not fully disclosed in this patent.

[0006] The above solutions focus more on the setting of resource status itself, but ignore a crucial safety issue: how to ensure that the train is in the correct and safe state of knowing that a special operation is being performed when it applies for shared resources.

[0007] Therefore, there is an urgent need in the art for a resource management method to solve the safety problem of trains in resource sharing. SUMMARY

[0008] The present application at least partially solves the above technical problems, and provides a marshalling or unmarshalling area resource sharing management method and system.

[0009] The first aspect of the embodiments of the present disclosure provides a marshalling or unmarshalling area resource sharing management method, comprising: According to the marshalling or unmarshalling operation instruction issued by the automatic supervision subsystem ATS, the target controller OC sets the resource of the marshalling or unmarshalling area to be only allowed to be occupied by the on-board subsystem OBC of the designated train in a shared application mode; According to the marshalling or unmarshalling operation instruction issued by the automatic supervision subsystem ATS, the on-board subsystem OBC of the designated train switches the resource application mode of the marshalling or unmarshalling area from an exclusive application mode to a shared application mode, and initiates the shared application to the target controller OC to obtain the resource of the marshalling or unmarshalling area, and the designated train performs the marshalling or unmarshalling operation; the exclusive application mode refers to that after the on-board subsystem OBC of the designated train successfully applies for the resource, the resource applied by the on-board subsystem OBC is only allowed to be occupied by itself; the shared application mode refers to that after the on-board subsystem OBC of the designated train successfully applies for the resource, the resource applied by the on-board subsystem OBC is allowed to be occupied by multiple designated trains; After the designated train completes the marshalling or unmarshalling operation, the on-board subsystem OBC of the designated train releases the resource of the marshalling or unmarshalling area, and applies for the cancellation and reconstruction of the train identity to the target controller OC.

[0010] The technical scheme provided in the present application at least brings the following beneficial effects: through the above method, the shared use of the resource of the same area by multiple trains during the marshalling or unmarshalling operation is realized, and through the switching of the resource application mode and the reconstruction of the train identity, the safety of the operation process and the effective management of the system resource are ensured.

[0011] In some other embodiments of the present application, in order to ensure the safety state of the train before entering the shared area during the marshalling operation, according to the marshalling or unmarshalling operation instruction issued by the automatic supervision subsystem ATS, the on-board subsystem OBC of the designated train performs safety verification, and after passing the safety verification, switches the resource application mode of the marshalling or unmarshalling area from an exclusive application mode to a shared application mode, and initiates the shared application to the target controller OC; When the coupling operation is performed, the designated train includes a coupled train and a decoupled train, the step of performing the safety check includes: The on-board subsystem OBC of the coupled train checks whether the end point of the exclusive resource held by the on-board subsystem OBC is continuous with the start point of the coupling area, if the end point of the exclusive resource is continuous with the start point of the coupling area and the resource of the coupling area is not occupied by other vehicles, the on-board subsystem OBC of the coupled train switches the resource application mode of the coupling area from exclusive application to shared application, and initiates the shared application to the target controller OC.

[0012] The technical scheme provided by the application at least brings the following beneficial effects: through the above safety check step, it is ensured that the coupled train is in the correct physical position before entering the coupling area, and the coupling area is not occupied, thereby providing a guarantee for the safe start of the coupling operation.

[0013] In some other embodiments of the application, in order to ensure that the decoupled train safely enters the coupling area and cooperates with the coupled train, the step of performing the safety check further includes: After the on-board subsystem OBC of the coupled train acquires the resource of the coupling area, the on-board subsystem OBC of the decoupled train checks whether the end point of the exclusive resource held by the on-board subsystem OBC is continuous with the start point of the coupling area, if continuous, and the resource of the coupling area is held by the on-board subsystem OBC of the coupled train, the on-board subsystem OBC of the decoupled train switches the resource application mode of the coupling area from exclusive application to shared application, and initiates the shared application to the target controller OC.

[0014] The technical scheme provided by the application at least brings the following beneficial effects: through the above steps, it is ensured that the path of the decoupled train is continuous with the coupling area before entering the coupling area, and the coupling area is occupied by the correct train, thereby avoiding resource conflicts and operation risks.

[0015] In some other embodiments of the application, in order to realize the action cooperation between trains in the coupling operation and ensure the synchronization and safety of the operation, the step of performing the safety check further includes: If the end point of the exclusive resource held by the OBC of the uncoupling train is continuous with the start point of the coupling area, the OBC of the uncoupling train acquires the coupling action information of the coupled train through the wireless communication network between the uncoupling train and the coupled train to confirm whether the coupled train is ready for the coupling operation, if yes, switches the resource application mode of the coupling area from exclusive application to shared application, and initiates the shared application to the target controller OC; if no, continuously acquires the coupling action information of the coupled train until the coupled train is ready for the coupling operation.

[0016] The technical scheme provided in the application at least brings the following beneficial effects: through the above steps, real-time state synchronization and action coordination between the coupled trains are realized, it is ensured that both sides are ready before entering the shared area, and the reliability and safety of the coupling operation are improved.

[0017] In some other embodiments of the application, in order to ensure the safety of the train separation process and the correctness of resource management in the uncoupling operation, according to the coupling or uncoupling operation instruction issued by the automatic supervision subsystem ATS, the OBC of the designated train performs a safety check, and after passing the safety check, switches the resource application mode of the coupling or uncoupling area from exclusive application to shared application, and initiates the shared application to the target controller OC. When performing the uncoupling operation, the designated train includes a train to be uncoupled, and the step of performing the safety check includes: According to the uncoupling operation instruction issued by the automatic supervision subsystem ATS, the OBC of the train to be uncoupled logs out its coupled train identity to the target controller OC, and the train to be uncoupled is physically uncoupled into a first single-formation train and a second single-formation train. The OBC of the first single-formation train and the OBC of the second single-formation train register independent train identities to the target controller OC respectively, after obtaining the independent train identities, the OBC of the first single-formation train and the OBC of the second single-formation train switch the resource application mode of the uncoupling area from exclusive application to shared application, and initiate the shared application to the target controller OC.

[0018] The technical scheme provided in the application at least brings the following beneficial effects: through the above steps, the smooth conversion of train identities and the switching of resource application modes in the uncoupling process are realized, and it is ensured that each train after uncoupling can independently and safely use the resources of the shared area.

[0019] In some other embodiments of the present application, to further ensure the correctness of the resource holding state in the uncoupling operation and avoid resource conflicts, the step of performing the security check further comprises: After obtaining the independent train identity, the on-board subsystem OBC of the first single-formation train and the on-board subsystem OBC of the second single-formation train respectively send information to the target controller OC to query the holder of the resource in the uncoupling area; When the holder of the resource in the uncoupling area is the target controller OC or the holder is one of the first single-formation train and the second single-formation train, the on-board subsystem OBC of the first single-formation train and the on-board subsystem OBC of the second single-formation train respectively switch the resource application mode in the uncoupling area from exclusive application to shared application, and initiate the shared application to the target controller OC.

[0020] The technical solution provided by the present application at least brings the following beneficial effects: through the above steps, it is ensured that the uncoupled train confirms that the resource is not occupied by an irrelevant train before applying for a shared resource, thereby avoiding resource conflicts and ensuring the safe performance of the uncoupling operation.

[0021] In some other embodiments of the present application, to realize the unification of train identities and the release of resources after the coupling operation is completed, after the uncoupled train and the coupled train complete the coupling operation, the resource in the coupling area is released, and the target controller OC is applied for the cancellation and reconstruction of the train identity, further comprising: The on-board subsystem OBC of the uncoupled train and the on-board subsystem OBC of the coupled train release the resource in the coupling area to the target controller OC; The on-board subsystem OBC of the uncoupled train and the on-board subsystem OBC of the coupled train cancel the independent train identity of each to the target controller OC; The on-board subsystem OBC of the new train after coupling is completed applies to the target controller OC for registration of the coupled train identity.

[0022] The technical solution provided by the present application at least brings the following beneficial effects: through the above steps, the merging of train identities and the unified management of resources after the coupling operation is completed are realized, and the effective release of system resources and the accurate reconstruction of train identities are ensured.

[0023] In some other embodiments of the present application, to realize the exclusive recovery of resources after the uncoupling operation is completed and avoid resource waste, after the uncoupling operation is completed, the uncoupled train releases the resource in the uncoupling area, and applies to the target controller OC for the cancellation and reconstruction of the train identity, further comprising: The first single-formation train on-board subsystem OBC and the second single-formation train on-board subsystem OBC obtain the uncoupling action information of each other through the wireless communication network therebetween, and one of the first single-formation train on-board subsystem OBC and the second single-formation train on-board subsystem OBC switches the resource application mode of the uncoupling area from the shared application to the exclusive application if it is detected that the other has driven out of the uncoupling area, and sends the exclusive application to the target controller OC to convert the resource of the uncoupling area into exclusive resource.

[0024] The technical scheme provided in the application at least brings the following beneficial effects: through the above steps, it is ensured that the uncoupling area is timely restored to the exclusive resource state after the operation is completed, and it is avoided that the resource is in the shared state for a long time to affect the normal operation of other trains.

[0025] In some other embodiments of the application, to further ensure the availability of the resource before the coupling or uncoupling operation is started, according to the coupling or uncoupling operation instruction issued by the automatic supervision subsystem ATS, the target controller OC checks whether the resource of the coupling or uncoupling area is occupied by other vehicles, and if not, the target controller OC responds to the shared application initiated by the on-board subsystem OBC of the designated train, and the designated train performs the coupling or uncoupling operation.

[0026] The technical scheme provided in the application at least brings the following beneficial effects: through the above steps, the target controller OC finally confirms the resource state before the operation is started, ensures that the shared resource is not occupied by irrelevant vehicles, and thus improves the safety and reliability of the operation.

[0027] The second aspect of the embodiments of the present disclosure provides a coupling or uncoupling area resource sharing management system for performing the coupling or uncoupling area resource sharing management method provided in the first aspect of the embodiments of the present disclosure, comprising: The automatic supervision subsystem ATS is configured to issue the coupling or uncoupling operation instruction, and the coupling or uncoupling operation instruction comprises designated train information, coupling or uncoupling area information, and coupling or uncoupling action information; The target controller OC is configured to set the resource of the coupling or uncoupling area to be only allowed to be occupied by the on-board subsystem OBC of the designated train in a shared application according to the coupling or uncoupling operation instruction issued by the automatic supervision subsystem ATS; The on-board subsystem OBC of one or more designated trains is configured to: According to the coupling or uncoupling operation instruction issued by the automatic supervision subsystem ATS, switch the resource application mode of the coupling or uncoupling area from the exclusive application to the shared application, and initiate the shared application to the target controller OC to obtain the resource of the coupling or uncoupling area. After the designated train completes the coupling or uncoupling operation, the resources of the coupling or uncoupling area are released, and the target controller OC is applied for the cancellation and reconstruction of the train identity.

[0028] Compared with the prior art, the application effectively solves the contradiction between resource sharing and safety in the coupling and uncoupling operation by introducing the dynamic switching of the resource application mode, the cancellation and reconstruction of the train identity, and the multi-level safety verification mechanism, and improves the safety and reliability of the train autonomous operation system.

[0037] The passenger volume of urban rail transit in a day usually presents an uneven characteristic, and there is a significant tidal phenomenon in the time and spatial distribution. In order to improve the operation efficiency, the train is designed to be coupled (grouped) and uncoupled (split) at appropriate stations or regions in the operation organization, so as to realize flexible grouping to adapt to the passenger flow demand in different periods.

[0038] In the prior art, the concept of "resource" is generally used to manage the train running path in the communication-based train control (CBTC) system and the next generation train autonomous operation system (TACS). In order to ensure train safety, the line resource is usually designed to have exclusivity, that is, any resource can be held by only one train in an exclusive manner at the same time, which is similar to the mutual exclusion lock in the computer operating system, effectively preventing conflicts between trains.

[0039] However, this resource exclusive design principle is fundamentally contradictory to the actual needs of train coupling and uncoupling operations. In the coupling operation, two single-group trains need to enter the same coupling area at the same time, and their body envelopes must overlap; in the uncoupling operation, a long-group train needs to be split into two independent trains in the uncoupling area, and each train holds the resource of the area to leave. In these scenarios, if the exclusivity of the resource is still insisted, the operation will not be performed or cause a safety accident due to the inability to allocate the resource at the same time.

[0040] To solve the above problems, the present application provides a coupling or uncoupling area resource sharing management method and system, which will be explained in the specific implementation manner below in combination with the drawings.

[0041] The first aspect of the embodiments of the present disclosure discloses a coupling or uncoupling area resource sharing management method, as shown in the following steps: Figure 1 S01: The automatic supervision subsystem ATS issues a coupling or uncoupling operation instruction; It should be noted that the coupling or uncoupling operation instruction includes designated train information, coupling or uncoupling area information, and coupling or uncoupling action information.

[0042] The coupling operation refers to the process of merging two independently operated trains (coupled trains and uncoupled trains) into a long-group train in a designated coupling area.

[0043] In a specific illustrative embodiment, when the train performs the coupling operation, the coupling operation instruction includes coupled train information, uncoupled train information, coupling area information, and coupling action information.

[0044] ​The uncoupling operation refers to a process in which a train to be uncoupled is separated into two independent short-coupling trains (a first single-coupling train and a second single-coupling train) in a designated uncoupling area.

[0045] In a specific illustrative embodiment, when the train performs the uncoupling operation, the uncoupling operation instruction includes train to be uncoupled information, uncoupling area information, and uncoupling action information.

[0046] S02: According to the coupling or uncoupling operation instruction issued by the automatic supervision subsystem ATS, the target controller OC sets the resources of the coupling or uncoupling area to be occupied only by the on-board subsystem OBC of the designated train with a shared application. As shown in Figure 2 , 4 In a specific illustrative embodiment, when the train performs the coupling operation, according to the coupling operation instruction issued by the automatic supervision subsystem ATS, the target controller OC sets the resources of the coupling area to be occupied only by the on-board subsystem OBC of the coupled train and the uncoupled train with a shared application.

[0047] As shown in Figure 3 , 5 In a specific illustrative embodiment, when the train performs the uncoupling operation, according to the coupling operation instruction issued by the automatic supervision subsystem ATS, the target controller OC sets the resources of the uncoupling area to be occupied only by the on-board subsystem OBC of the train to be uncoupled with a shared application.

[0048] S03: According to the coupling or uncoupling operation instruction issued by the automatic supervision subsystem ATS, the on-board subsystem OBC of the designated train switches the resource application mode of the coupling or uncoupling area from exclusive application to shared application, and initiates a shared application to the target controller OC to obtain the resources of the coupling or uncoupling area, so that the designated train performs the coupling or uncoupling operation. It needs to be explained that exclusive application means that after the on-board subsystem OBC of the designated train successfully applies for resources, the resources it applies for are only allowed to be occupied by itself; shared application means that after the on-board subsystem OBC of the designated train successfully applies for resources, the resources it applies for are allowed to be occupied by multiple designated trains. Before performing the coupling operation, the on-board subsystem OBC of the coupled train and the uncoupled train applies for resources with exclusive application, and the successfully applied resources are only allowed to be occupied by itself; when performing the coupling operation, the on-board subsystem OBC of the coupled train applies for resources with a shared application, and the successfully applied resources are allowed to be occupied by the uncoupled train, and correspondingly, the on-board subsystem OBC of the uncoupled train applies for resources with a shared application, and the successfully applied resources are allowed to be occupied by the coupled train.

[0049] As shown in Figure 4As shown in the specific illustrative embodiment, when the train performs the coupling operation, according to the coupling operation instruction issued by the automatic supervision subsystem ATS, the on-board subsystem OBC of the coupled train and the uncoupling train switches the resource application mode of the coupling area from exclusive application to shared application, and initiates a shared application to the target controller OC to obtain the resources of the coupling area, and after obtaining the resources of the coupling area, the coupled train and the uncoupling train perform the coupling operation.

[0050] As shown in the specific illustrative embodiment, when the train performs the coupling operation, according to the coupling operation instruction issued by the automatic supervision subsystem ATS, the on-board subsystem OBC of the coupled train and the uncoupling train switches the resource application mode of the coupling area from exclusive application to shared application, and initiates a shared application to the target controller OC to obtain the resources of the coupling area, and after obtaining the resources of the coupling area, the coupled train and the uncoupling train perform the coupling operation. Figure 5

[0051] S04: After the designated train completes the coupling or uncoupling operation, the on-board subsystem OBC of the train releases the resources of the coupling or uncoupling area, and applies to the target controller OC for cancellation and reconstruction of the train identity.

[0052] As shown in the specific illustrative embodiment, when the train performs the coupling operation, according to the coupling operation instruction issued by the automatic supervision subsystem ATS, the on-board subsystem OBC of the coupled train and the uncoupling train switches the resource application mode of the coupling area from exclusive application to shared application, and initiates a shared application to the target controller OC to obtain the resources of the coupling area, and after obtaining the resources of the coupling area, the coupled train and the uncoupling train perform the coupling operation. Figure 4 The on-board subsystem OBC of the uncoupling train and the on-board subsystem OBC of the coupled train release the resources of the coupling area to the target controller OC; The on-board subsystem OBC of the uncoupling train and the on-board subsystem OBC of the coupled train cancel their respective independent train identities to the target controller OC; The on-board subsystem OBC of the new train after coupling applies to the target controller OC for registration of the coupled train identity.

[0053] The technical solution provided by the present application realizes the merging of the train identity and the unified management of the resources after the coupling is completed through the above steps, and ensures the effective release of the system resources and the accurate reconstruction of the train identity.

[0054] As shown in the specific illustrative embodiment, when the train performs the coupling operation, according to the coupling operation instruction issued by the automatic supervision subsystem ATS, the on-board subsystem OBC of the coupled train and the uncoupling train switches the resource application mode of the coupling area from exclusive application to shared application, and initiates a shared application to the target controller OC to obtain the resources of the coupling area, and after obtaining the resources of the coupling area, the coupled train and the uncoupling train perform the coupling operation. Figure 5 ​​​The on-board subsystem OBC of the first single-formation train and the on-board subsystem OBC of the second single-formation train obtain the disassembly action information of each other through the wireless communication network therebetween, and one of the on-board subsystem OBC of the first single-formation train and the on-board subsystem OBC of the second single-formation train switches the resource application mode of the disassembly area from shared application to exclusive application if it is detected that the other has driven out of the disassembly area, and sends the exclusive application to the target controller OC to convert the resource of the disassembly area into exclusive resource.

[0055] The technical solution provided in the application ensures that the disassembly area is timely restored to the exclusive resource state after the operation is completed, and avoids the resource being in the shared state for a long time to affect the normal operation of other trains.

[0056] The resource sharing management method for the coupling or disassembly area provided in the application introduces a new controlled mode, i.e., "shared application", so that the safety basis of the system in processing the coupling or disassembly operation is changed from rigid "exclusive use of physical space" to more intelligent "shared use of logical permission". It recognizes that the safe co-area of multiple trains is possible under certain conditions, and establishes a new safety standard for the co-area by strictly defining the rules of "shared application", realizes the shared use of the resource of the same area by multiple trains in the coupling or disassembly operation process, and ensures the safety of the operation process and the effective management of system resources.

[0057] In some other embodiments of the application, the resource sharing method for the coupling or disassembly area further includes: According to the coupling or disassembly operation instruction issued by the automatic supervision subsystem ATS, the on-board subsystem OBC of the designated train performs safety check, and after passing the safety check, switches the resource application mode of the coupling or disassembly area from exclusive application to shared application, and initiates shared application to the target controller OC; As shown in Figure 4 When the coupling operation is performed, the designated train includes the coupled train and the decoupled train, and the step of performing safety check includes: The on-board subsystem OBC of the coupled train checks whether the end point of the exclusive resource held by itself is continuous with the start point of the coupling area, if the end point of the exclusive resource is continuous with the start point of the coupling area, and the resource of the coupling area is not occupied by other vehicles, the on-board subsystem OBC of the coupled train switches the resource application mode of the coupling area from exclusive application to shared application, and initiates shared application to the target controller OC.

[0058] It is necessary to explain that the end of the exclusive resource held by itself refers to the last physical position of the last line resource block successfully applied and exclusively occupied by the currently connected train. Among them, "held by itself": emphasizes that the resource is legally occupied by this connected train and is part of its current movement authorization; "exclusive resource": refers to the occupation state of the resource in the "exclusive application" mode, and the system does not allow any other train to occupy it at the same time; "end point": refers to the last position that the train can reach allowed by the "safe pass certificate" currently owned by the train.

[0059] In a specific illustrative embodiment, assuming that the line resources are numbered in sequence as... R5, R6, R7, R8, R9, R10... The connected train is driving from west to east, and it has successfully occupied resources R6 and R7, so the "end of the exclusive resource held by itself" is the east boundary of resource R7.

[0060] The start point of the coupling area refers to the starting physical position of the shared area for coupling operation specified by the automatic supervision subsystem ATS in the coupling operation instruction. The "coupling area" is a special resource block that is predefined for coupling operations. When the operation is performed, its resource attribute will change from "exclusive" to "shared". "Start point": refers to the starting point of the coupling area resource block in the direction of train movement.

[0061] In a specific illustrative embodiment, assuming that the line resources are numbered in sequence as... R5, R6, R7, R8... Assuming that the coupling area specified by the automatic supervision subsystem ATS is resource R8. Then, the "start point of the coupling area" is the west boundary of resource R8.

[0062] In a specific illustrative embodiment, the line resources are numbered in sequence as... R5, R6, R7, R8... The connected train is driving from west to east, and it has successfully occupied resources R6 and R7, and the coupling area specified by the automatic supervision subsystem ATS is resource R8. When performing the coupling operation, the steps of the connected train performing safety verification include: The on-board subsystem OBC of the connected train checks whether the end of the exclusive resource held by itself is continuous with the start point of the coupling area, i.e., whether the east boundary of resource R7 is continuous with the west boundary of resource R8. If the east boundary of resource R7 is continuous with the west boundary of resource R8, and the coupling area resource, i.e., resource R8, is not occupied by other vehicles, the on-board subsystem OBC of the connected train will switch the resource application mode of the coupling area from exclusive application to shared application, and initiate a shared application to the target controller OC.

[0063] This technical solution ensures that the coupled train is in the correct physical position before entering the coupling area through the above safety verification steps, and that the coupling area is not occupied, thus providing a guarantee for the safe start of coupling operations.

[0064] like Figure 4 As shown, in some other embodiments of this application, the step of performing security verification further includes: After the Onboard Control (OBC) of the coupled train acquires the resources of the coupled area, the Onboard Control (OBC) of the train to be coupled verifies whether the endpoint of its exclusive resources is continuous with the starting point of the coupled area. If they are continuous, and the resources of the coupled area are already held by the Onboard Control (OBC) of the coupled train, the Onboard Control (OBC) of the train to be coupled switches the resource request mode of the coupled area from exclusive request to shared request, and initiates a shared request to the target controller (OC).

[0065] In a specific illustrative embodiment, the line resources are sequentially numbered as... R5, R6, R7, R8, R9, R10... The coupled train is traveling from west to east and has successfully occupied resources R6 and R7. The coupling area designated by the Automatic Supervision Subsystem (ATS) is resource R8. The decoupling train is traveling from east to west and has successfully occupied resources R9 and R10. The endpoint of the decoupling train's exclusive resource is the western side of resource R9. The safety verification steps further include: After the onboard subsystem OBC of the coupled train acquires resource R8 in the coupled area, the onboard subsystem OBC of the train to be coupled verifies whether the endpoint of its exclusive resource is continuous with the starting point of the coupled area. That is, it checks whether the western side of resource R9 is continuous with the eastern side of resource R8. If they are continuous, and resource R8 in the coupled area is already held by the onboard subsystem OBC of the coupled train, the onboard subsystem OBC of the train to be coupled switches the resource R8 application mode of the coupled area from exclusive application to shared application and initiates a shared application to the target controller OC.

[0066] The technical solution of this application ensures, through the above steps, that the path of the train going to the coupling area is continuous with the coupling area before entering the coupling area, and that the coupling area has been correctly occupied by the train, thus avoiding resource conflicts and operational risks.

[0067] like Figure 4 As shown, in some other embodiments of this application, the step of performing security verification further includes: If the end point of the exclusive resource checked by the OBC of the uncoupling train and the start point of the coupling area are continuous, the OBC of the uncoupling train acquires the coupling action information of the coupled train through the wireless communication network between the uncoupling train and the coupled train, to confirm whether the coupled train has prepared for the coupling operation, if yes, the resource application mode of the coupling area is switched from exclusive application to shared application, and the target controller OC is initiated for shared application; if not, the coupling action information of the coupled train is continuously acquired until the coupled train has prepared for the coupling operation.

[0068] It needs to be explained that the wireless communication network is set between the trains, and the data interaction is realized through train-to-train communication. The wireless communication network usually follows specific international or industry standards, such as IEEE 802.11p (ITS-G5), LTE-V2X (Vehicle-to-Everything) or more advanced 5G-NR V2X. These standards are dedicated to train-to-train / vehicle-to-thing communication, supporting high reliability, low latency data transmission in high mobility scenarios. That is, the data of the train is directly transmitted between the uncoupling train and the coupled train without passing through the base station or the network core network.

[0069] It needs to be explained that the confirmation of whether the train to be coupled has prepared for the coupling operation is an objective and logical determination process based on specific state parameters that can be monitored and reported within the train control system. It takes specific "coupling action information" as the basis for confirmation, and whether the train to be coupled is "ready" is usually determined by the combination of several key subsystem states. Only when all these necessary states reach the preset "ready" value, it is determined that the preparation is ready. Several key subsystem states usually include mechanical coupling system state, electrical and data connection system state, brake and air pipe system state and train control state. The information representing the mechanical coupling system state, such as the coupler state, when the train to be coupled has prepared for the coupling operation, the coupler must be in the state of "fully extended and mechanically locked", the system will monitor the travel sensor of the coupler extension mechanism and the sensor signal of the locking device to ensure that the coupler has reached the correct position and is locked. If the coupler is not extended, the coupler is extended, or the coupler locking fails, it indicates that the mechanical coupling system state is not ready, and the train to be coupled is not ready for the coupling operation. The information representing the electrical and data connection system state includes the electrical connector state, such as when the train to be coupled has prepared for the coupling operation, the electrical connector for connecting the communication and control lines of the two trains must be in the "ready" state, which may mean that the connector cover plate is opened and the interface is in a connectable state. If the connector is covered by the protective cover or the connector fails, it indicates that the electrical and data connection system state is not ready, and the train to be coupled is not ready for the coupling operation. The information representing the brake and air pipe system state includes the brake state and the air pipe interface state, such as the train brake system keeps the brake applied to ensure that the train will not move unexpectedly; the interface plug door for connecting the brake air pipes of the two trains is opened, and the air pipe head is in the ready state of being exposed. After receiving the above state information from the train to be coupled, the OBC of the uncoupling train will perform an automatic logical determination to determine whether the train to be coupled has prepared for the coupling operation.

[0070] In a specific illustrative embodiment, the line resources are numbered in sequence as... R5, R6, R7, R8, R9, R10.... The train to be coupled is driving from west to east, it has successfully occupied resources R6 and R7 at present, the coupling area designated by the automatic supervision subsystem ATS is resource R8, the uncoupling train is driving from east to west, the uncoupling train itself holds exclusive resources, and the end of the exclusive resources is the west side of resource R9. The step of performing safety check further includes: If the west side of the resource R9 is continuous with the east side of the resource R8, the on-board subsystem OBC of the uncoupling train acquires the coupling action information of the coupled train through the wireless communication network between the uncoupling train and the coupled train, performs an automatic logical judgment through the above coupling action information, confirms whether the coupled train has prepared for the coupling operation, if yes, switches the resource application mode of the coupling area from exclusive application to shared application, and initiates the shared application to the target controller OC; if no, continuously acquires the coupling action information of the coupled train until the coupled train has prepared for the coupling operation.
