[0009] The system acquires the real-time location of the target train formation system and, when the real-time location reaches the decoupling position, issues a decoupling command to the target train formation system. This enables the target train formation system to generate a decoupling command confirmation message based on the decoupling command and exit the formed state to enter the unformed state. When the target train formation system exits the formed state, each following train system disconnects its communication connection with the corresponding preceding train system.

[0010] In one embodiment, when the target train formation system enters the formed state, the train virtual formation method further includes:

The formation conditions include that the current parameters of the target train formation system meet the preset parameter requirements. The target train formation system includes the lead car system and multiple follower car systems that follow the lead car system in sequence. Each follower car system establishes a communication connection with the corresponding lead car system according to the formation command.

[0028] The feedback information receiving module is used to receive the formation command confirmation information fed back by the target formation train system based on the formation command, and to send the formation status information to the target formation train system so that the target formation train system enters the formation state.

[0029] The ungrouping position confirmation module is used to determine the ungrouping position according to the grouping plan;

[0030] The uncoupling command issuing module is used to obtain the real-time position of the target train formation system and, when the real-time position reaches the uncoupling position, issue an uncoupling command to the target train formation system. This allows the target train formation system to generate an uncoupling command confirmation message based on the uncoupling command and exit the formed state to enter the unformed state. When the target train formation system exits the formed state, each following car system disconnects its communication connection with the corresponding preceding car system.

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0042] It should be noted that the terms "comprising" and "having," and any variations thereof, as used in this application, are intended to cover non-exclusive inclusion. The term "multiple" as used in this application refers to two or more.

[0043] Traditional technologies are limited by train-to-train communication technology, have strict train formation conditions, poor train formation stability, and also suffer from low scheduling efficiency and low resource utilization.

[0044] The train virtual formation method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, the CTC (Centralized Traffic Control) 102 transmits the grouping plan issued by the dispatcher to the RBC (Radio Block). The radio block center 104, when the formation conditions are met, issues a formation command to the target formation train system 106, which is in an unformed state, so that each following train system in the target formation train system 106 establishes a communication connection with its corresponding preceding train system according to the formation command. Then, it receives the formation command confirmation information fed back by the target formation train system 106 based on the formation command, and issues formation status information to the target formation train system 106 so that the target formation train system 106 enters the formed state. According to the formation plan, it determines the de-formation position. It obtains the real-time position of the target formation train system 106, and when the real-time position reaches the de-formation position, it issues a de-formation command to the target formation train system 106 so that the target formation train system 106 generates a de-formation command confirmation information according to the de-formation command, and exits the formed state and enters the unformed state. When the target formation train system 106 exits the formed state, each following train system disconnects its communication connection with its corresponding preceding train system.

[0045] In one exemplary embodiment, such as Figure 2 and Figure 3 As shown, a method for virtual train formation is provided, which can be applied to... Figure 1 The following explanation uses the radio block center 104 as an example, including:

[0046] S202 receives the train formation plan issued by the centralized train dispatching system.

[0047] S204, under the condition that the formation conditions are met, a formation command is issued to the target train system that is not in a formation state. The formation conditions include that the current parameters of the target train system meet preset parameter requirements. The target train system includes the lead car system and multiple follower car systems sequentially following the lead car system. Each follower car system establishes a communication connection with its corresponding lead car system according to the formation command. The target train system can be understood as ATP (Automatic Train Protection), the lead car system as the lead car ATP, and the follower car systems as follower car ATP.

[0048] Current parameters include the current mode of the following cars, the running direction of each train in the target train formation system, the permitted travel endpoint of each following car system in the target train formation system, the current position of each train in the target train formation system, and the integrity status of each train in each target train formation system. Formation conditions include: the position of the lead car is known, and the following cars are in full mode; the running direction of each train in the target train formation system is consistent with the direction of the formation plan; the permitted travel endpoint of each following car system in the target train formation system is the tail of the corresponding lead car; the current position of each train in the target train formation system has not crossed the formation checkpoint of the formation section; and each train in each target train formation system possesses integrity.

[0049] Under the condition that the above-mentioned formation conditions are met, the radio block center issues a formation command to the target train formation system.

[0050] S206 Receive the formation command confirmation information from the target formation train system based on the formation command feedback, and send formation status information to the target formation train system so that the target formation train system enters the formation state.

[0051] Upon receiving a formation command, the target train formation system sends a formation command confirmation message to the radio block center and, based on the formation command, establishes a communication connection between each following train system and its corresponding preceding train system.

[0052] After establishing communication connections between vehicles, the preceding vehicle's system periodically reports the current driving parameters of the preceding vehicle to the corresponding following vehicle's system. These current driving parameters include position, speed, integrity, wind pressure information, acceleration, control status information, and odometer readings.

[0053] When the target train formation system enters the formation state, it periodically sends a formation operation report to the radio block center. The formation operation report includes the distance difference between the EOA (End of Authority) calculated by the target train formation system and the EOA calculated by the radio block center.

[0054] Once the radio block center receives confirmation of the writing command from the target train formation system, the radio block center can consider that the target train formation has been successfully formed.

[0055] S208, determine the disassembly position according to the formation plan.

[0056] S210: Obtain the real-time position of the target train formation system, and when the real-time position reaches the disassembly position, issue a disassembly command to the target train formation system so that the target train formation system generates a disassembly command confirmation message according to the disassembly command, and exits the formed state and enters the unformed state; wherein, when the target train formation system exits the formed state, each following car system disconnects its communication connection with the corresponding preceding car.

[0057] When the target train formation system receives a disbanding command, the status of the target train formation system is updated to un-formed in the formation, the target train formation system is removed from the formation occupancy, and then a disbanding command confirmation message is generated and output to the radio block center, thereby completing the disbanding.

[0058] Therefore, compared with the traditional virtual train formation method, based on the above-mentioned virtual train formation method, the radio block center believes that the conditions for successful formation no longer depend on the vehicle-to-vehicle communication technology of the target train formation system, and the radio block center and the target train formation maintain their respective corresponding formation status, reducing the coupling relationship between the two and making the formation status more stable.

[0059] Furthermore, the wireless block center can also transmit the current status of the target train formation system to ground equipment such as the centralized dispatching system.

[0060] In an exemplary embodiment, when the target train formation system enters the formed state, the above-described train virtual formation method further includes:

[0061] The train operation permit endpoint of the first train system is sent to the first train system of the target train formation system, so that the target train formation system can determine the emergency braking stop point based on the train operation permit endpoint of the first train system and the preceding train information, and enter the virtual formation mode.

[0062] When the radio block center sends the train permission endpoint of the first train system to the first train system, the target train formation can determine the distance difference between the two based on the train permission endpoint of the radio block center and the train permission endpoint of the target train formation.

[0063] When the target train formation system has entered the formation state, the travel permit endpoint sent by the radio block center includes travel permit endpoint type information, which indicates the train is behind the preceding train. When the travel permit endpoint type information indicates the train is behind the preceding train, the real-time position of the target train formation system can be the real-time position of the leading train. Once the target train formation system has entered the formation state, car-to-car communication has been established, meaning each following car system establishes a communication connection with its corresponding preceding car system according to the formation command. Therefore, the target train formation system can determine the emergency braking point based on the travel permit endpoint of the leading car system and the preceding train information, and the route data of the target train formation system is sufficient to cover the emergency braking point of the preceding train.

[0064] When the target train formation system enters virtual formation mode, the target train formation system can report its position to the radio block center.

[0065] When the target train formation system enters the virtual formation mode, the target train formation system determines that the formation is successful.

[0066] In an exemplary embodiment, when the target train system enters the virtual train formation mode, the lead car system in the target train system determines the absolute braking distance curve based on the driving permission endpoint of the lead car system; each following car system in the target train system determines the relative braking distance curve based on the preceding car information of the corresponding preceding car system.

[0067] After the target train formation system enters virtual formation mode, the lead car system still uses the train operation permit endpoint sent by the radio block center to achieve absolute braking distance curve monitoring. The following car should calculate the virtual formation train operation permit based on the information of the preceding car. The train operation permit endpoint for the following car is the tail end of the corresponding preceding car minus a certain safety distance, that is, monitoring the train using the relative braking distance curve. The safety distance can be configured according to safety requirements.

[0068] In an exemplary embodiment, after the train formation status information is sent to the target train formation system, and before the de-formation position is determined according to the formation plan, the above-mentioned train virtual formation method further includes:

[0069] Based on the formation plan, determine the location for the disbanding announcement.

[0070] The system acquires the real-time location of the target train formation and, when the real-time location reaches the decoupling warning location, sends a decoupling warning to the target train formation so that the target train formation can generate decoupling warning confirmation information and braking distance parameters based on the decoupling warning; the braking distance parameters include absolute braking distance curves and relative braking distance curves.

[0071] Obtain the current operating speed of the target train formation system.

[0072] If the current operating speed is less than the first speed allowed by the absolute braking distance curve, the control target train formation system exits the virtual formation mode and enters the full mode.

[0073] When the current operating speed is greater than the second speed allowed by the absolute braking distance curve, the control target train formation system generates and outputs deceleration warning information.

[0074] According to the train formation plan, when the real-time location reaches the decoupling warning position, the radio block center sends a decoupling warning to the target train formation system.

[0075] Upon receiving the dismounting notice, the target train formation system sends a dismounting notice confirmation message to the radio block center and calculates the absolute braking distance curve and the relative braking distance curve. If the current operating speed is less than the first speed allowed by the absolute braking distance curve, the system controls the target train formation system to exit the virtual formation mode and enter full mode. Once the target train formation system enters full mode, car-to-car communication is disconnected.

[0076] When the current operating speed is greater than the second speed allowed by the absolute braking distance curve, the target train system generates and outputs a deceleration prompt message to remind the driver to decelerate to the target speed. When the driver controls the train to decelerate to below the target speed, the current operating speed is less than the first speed allowed by the absolute braking distance curve. Therefore, the target train system exits the virtual train formation mode and enters the full mode.

[0077] If the virtual formation mode of the target train formation system fails, the target train formation enters full mode. In full mode, the system employs absolute braking distance curve control and maintains the formed-up status, thereby ensuring robustness and improving line operating efficiency.

[0078] In one exemplary embodiment, the above-described train virtual formation method further includes:

[0079] In the event of a malfunction, a disassembly command is issued to the target train formation system.

[0080] The faults include: loss of integrity of at least one train in the target train formation system; the running direction of some trains in the target train formation system being different from that of the remaining trains; communication interruption between at least one train in the target train formation system and the radio block center; and at least one train in the target train formation system exiting full mode or virtual formation mode.

[0081] In the event of any of the above faults, the radio block center issues a disassembly command to the target train formation system and sets the formation status to unformed. At this time, the radio block center considers the target train formation system to be in an unformed state.

[0082] In one exemplary embodiment, the above-described train virtual formation method further includes:

[0083] Upon receiving fault information from the target train following system, a disassembly command is sent to the target train group system.

[0084] Specifically, when the target train system is in a assembled state and there is at least one target following train system, the target following train system re-establishes communication connection with the corresponding preceding train system within a preset time window; outside the preset time window, the target following train system outputs fault information; wherein, the target following train system is the following train system that has disconnected its communication connection with the corresponding preceding train system.

[0085] If a train-to-train communication interruption occurs while the target train formation system is already in a formed state, it is assumed that the communication is still established. Therefore, the train whose communication was interrupted needs to continue attempting to establish a communication connection with the corresponding preceding train until that connection is established. During the reconnection of train-to-train communication, neither the target train formation system nor the radio block center needs to participate, and both the target train formation system and the radio block center still consider the target train formation system to be in a formed state, thus achieving autonomous reconnection of train-to-train communication.

[0086] If the reconnection time of vehicle-to-vehicle communication exceeds a preset time window, a disassembly command is issued to the target train formation system. This causes the target train formation system to generate a disassembly command confirmation message, exit the formed-up state, and enter the unformed state. The preset time window can be 5 minutes and is configurable.

[0087] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages in other steps. It is understood that the steps in different embodiments can be freely combined as needed, and all non-contradictory solutions formed by such combinations are within the scope of protection of this application.

[0101] The speed acquisition module is used to obtain the current operating speed of the target train formation system.

[0102] The first speed comparison module is used to control the target train formation system to exit the virtual formation mode and switch to full mode when the current operating speed is less than the first speed allowed by the absolute braking distance curve.

[0103] The second speed comparison module is used to control the target train formation system to generate and output deceleration warning information when the current operating speed is greater than the second speed allowed by the absolute braking distance curve.
