Description

Technical Field

[0001] This invention relates to the field of rail transit train operation control technology, and in particular to a collaborative processing method and system for abnormal decomposition of virtual train formations. Background Technology

[0002] With the development of rail transit technology, virtual train formation control systems have gradually become a research hotspot. Based on existing moving block train control systems, virtual train formation control systems utilize vehicle-to-vehicle communication technology to "virtually connect" two or more adjacent trains to form a virtual train formation. This system treats multiple trains as a single entity, forming a logical community to complete train control and scheduling. It can significantly reduce the tracking distance between trains, shorten intervals, and thus improve line transport capacity and train operation efficiency.

[0003] In the existing virtual train formation control system, when a virtual train formation passes through the station ahead normally, it usually follows a predetermined control procedure: the interlocking system completes the route, and when the train formation approaches the signal, the Radio Block Center (RBC) sends a "train formation approaching" message to the interlocking system, which then sets the signal to an allowed-to-off state (e.g., green light off); after the head of the last car in the train formation passes the signal, the RBC sends a "train formation crossing" message, and the interlocking system sets the signal to a prohibited state (e.g., red light on); after the tail of the last car in the train formation passes the signal, the route is unlocked one by one according to the train occupancy status.

[0004] However, the existing solutions only consider the normal passage of virtual train formations through stations and do not address abnormal situations. In actual operation, if a virtual train formation experiences abnormal disassembly (i.e., virtual connection disconnection) while approaching a signal, or after the lead car and part of the formation have passed a signal, the original control logic will be disrupted. At this time, the system will be unable to correctly provide critical information such as "train crossing," potentially leading to incorrect signal displays (e.g., displaying a permitted signal when a prohibition signal should be displayed), or incorrect route unlocking. These abnormal situations pose serious safety hazards and could even lead to accidents. Therefore, a method is urgently needed to handle abnormal disassembly during the entry of virtual train formations into stations to ensure train operation safety.

[0005] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a collaborative processing method and system for abnormal disassembly of virtual train formations, which can solve the problem of signal malfunction or route mislocking risk when abnormal disassembly occurs during the entry of existing virtual train formations.

[0007] To achieve the above objectives, the present invention provides a collaborative processing method for abnormal decomposition of virtual train formations, comprising the following steps: Step S1: Monitor whether the virtual train formation experiences abnormal disassembly during the station entry process using the monitoring module; if abnormal disassembly occurs, proceed to step S2. In step S2, the train relative position acquisition and judgment module acquires the position status of the virtual train relative to the entrance signal S, and determines the position information as "the lead car of the virtual train is approaching the entrance signal S" or "the lead car of the virtual train has passed the entrance signal S"; the train communication status acquisition and judgment module acquires and judges the communication status of the lead car in the corresponding position status, and classifies it into multiple downgraded train types according to the different communication statuses of the lead car, and generates corresponding downgraded train information; In step S3, the interlocking system executes corresponding control commands on the entry signal S based on the received various downgraded train information, and keeps the route locked until it is manually unlocked.

[0008] Optionally, in step S1, the monitoring module uses vehicle-to-vehicle communication link status monitoring and train position report consistency verification to determine in real time whether the "virtual connection" inside the virtual train formation is disconnected; when the "virtual connection" is detected to be disconnected, it indicates that the formation relationship has failed, which means that an abnormal disassembly has occurred.

[0009] Optionally, in step S2, the train communication status acquisition and judgment module acquires and judges the communication status of the lead car of the virtual train formation. When the communication status of the lead car is "normal communication", the lead car is judged as a downgraded "moving block train"; when the communication status of the lead car is "interrupted communication", the lead car is judged as a downgraded "non-communication car".

[0010] Optionally, in step S2, the downgraded train information includes: "moving block train approaching" information, "non-communication train approaching" information, "moving block train crossing" information, and "non-communication train crossing" information.

[0011] Optionally, in step S3, after the train communication status acquisition and judgment module sends the "moving block train approaching" information to the interlocking system, the interlocking system will execute the following actions on the entrance signal S along the route of the virtual train whose position status is "the lead car of the virtual train is approaching the entrance signal S": S3.1.1, control the entry signal S to keep the first indicator light off; S3.1.2, after the lead car continues to run and passes the station entry signal S, the train communication status acquisition and judgment module sends the "moving block train crossing" information to the interlocking system according to the train position report; S3.1.3 After receiving this information, the interlocking system controls the first indicator light of the entry signal S to turn off and then turn on the second indicator light, and forcibly keeps the route in an unlocked state until the dispatcher performs a manual unlocking operation.

[0012] Optionally, in step S3, after the train communication status acquisition and judgment module sends the "non-communication car approaching" information to the interlocking system, the interlocking system will execute the following actions on the entrance signal S along the route of the virtual train whose position status is "the lead car of the virtual train is approaching the entrance signal S": S3.2.1, controls the first indicator light of the station entry signal S to turn on; S3.2.2, after the lead car passes the station entry signal S, the train communication status acquisition and judgment module sends the "non-communication car crossing" information to the interlocking system according to the train position report; S3.2.3 After receiving this information, the interlocking system, based on the interlocking conditions of the track circuit occupancy check, controls the first indicator light of the entry signal S to change to the second indicator light, and forcibly keeps the route in an unlocked state until the dispatcher performs a manual unlocking operation.

[0013] Optionally, in step S3, after the train communication status acquisition and judgment module in the RBC sends the "moving block train crossing" information to the interlocking system, the following operations are performed: S3.3.1, the train communication status acquisition and judgment module continues to judge the communication status of the train following the lead train, and downgrades it according to its communication status; S3.3.2 When the communication status of the following train is "communication normal" and it is downgraded to a moving block train, the interlocking system sets the second indicator light of the entrance signal S to turn off and forcibly keeps the route locked until it is manually unlocked; Alternatively, when the communication status of the following train is "communication interrupted" and it is downgraded to a non-communication car, the interlocking system sets the second indicator light of the entry signal S to illuminate and forcibly keeps the route locked until it is manually unlocked.

[0014] Optionally, in step S3, after the train communication status acquisition and judgment module in the RBC sends the "non-communication car crossing" information to the interlocking system, the following is executed: S3.4.1, the interlocking system sets the second indicator light of the entry signal S to light up and forcibly keeps the route from unlocking until it is manually unlocked.

[0015] The present invention also provides a processing system for implementing the aforementioned collaborative processing method, the processing system comprising: The monitoring module is used to monitor the operating status of the virtual train formation during its entry into the station, as well as the integrity of the car-to-car communication link and the effectiveness of the formation relationship. The train relative position acquisition and judgment module is connected to the entrance signal S to acquire the position status of the train relative to the entrance signal S and to determine the position information of "the lead car of the virtual train is approaching the entrance signal S" or "the lead car of the virtual train has passed the entrance signal S". The train communication status acquisition and judgment module is deployed in the RBC. It is connected to the train relative position acquisition and judgment module and the monitoring module. It is used to acquire the communication status of the lead car of the train in a specific position state under abnormal disassembly conditions, and divide the virtual train into multiple downgraded train types according to the different communication statuses of the lead car, and generate corresponding downgraded train information. Upon receiving various downgraded train information, the interlocking system executes corresponding control commands on the station entry signal S and keeps the route locked until it is manually unlocked.

[0016] Optionally, the train communication status acquisition and judgment module performs the following judgment logic: If the train communication status acquisition and judgment module obtains that the communication status of the lead car at the position of "the lead car of the virtual train is approaching the station signal S" is "communication is normal", then it is judged to be a downgraded "moving block train" and "moving block train approaching" information is sent to the interlocking system. If the obtained communication status is "communication interruption", it is determined to be a downgraded "non-communication vehicle" and a "non-communication vehicle approaching" message is sent to the interlocking system.

[0017] Optionally, the train communication status acquisition and judgment module also performs the following judgment logic: If the train communication status acquisition and judgment module obtains that the communication status of the lead car at the position "the lead car of the virtual train has passed the entry signal S" is "communication normal", then it is judged to be a downgraded "moving block train" and "moving block train crossing" information is sent to the interlocking system. If the obtained communication status is "communication interruption", it is determined to be a downgraded "non-communication vehicle" and a "non-communication vehicle crossing" message is sent to the interlocking system.

[0018] Optionally, the train communication status acquisition and judgment module is also used to acquire the communication status of the train following the lead train, and determine it as a downgraded moving block train or a non-communication train based on its communication status.

[0019] In summary, compared with the prior art, the present invention has the following beneficial effects: 1. Fills the gap in safety control: This invention proposes a complete processing method for abnormal disassembly scenarios of virtual train formations that are not covered by existing technologies. It effectively solves the problems of incorrect signal display or route mislocking that may occur after abnormal disassembly, and eliminates safety hazards.

[0020] 2. Refined Situational Control: This invention fully considers the different states of the trains after formation (communication status and signal crossing situations) and formulates a situational control strategy for RBC and interlocking. Different signal display logics (lights off or on) are adopted for communicating and non-communication cars, which not only conforms to the operating characteristics of moving block trains and non-communication cars, but also ensures the rigor of the control logic.

[0021] 3. Improve system availability: Under the premise of ensuring safety, the present invention introduces a manual intervention mechanism. By maintaining the route until manual unlocking, the system is prevented from being directly locked due to abnormalities. This allows the train to continue running after manual confirmation of safety, significantly improving the availability of the virtual train formation control system. Attached Figure Description

Detailed Implementation

[0023] The following will be combined with the appendix Figures 1-4 The present invention will be further described in detail through preferred embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, only for the purpose of conveniently and clearly illustrating the embodiments of the present invention. Please refer to the accompanying drawings to make the objectives, features, and advantages of the present invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of the present invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives achieved by the present invention, should still fall within the scope of the technical content disclosed in the present invention.

[0024] This invention provides a collaborative processing method for abnormal de-merging of virtual train formations. This method is applied to virtual train formation control systems, including Radio Block Center (RBC) and Interlocking System (CBI), such as... Figure 4 As shown, the collaborative processing method includes the following steps: Step S1: Monitor whether the virtual train formation is abnormally disassembled during the station entry process using the monitoring module; if abnormal disassembly occurs, proceed to step S2.

[0025] Specifically, the monitoring module uses methods such as vehicle-to-vehicle communication link status monitoring and train position report consistency verification to determine in real time whether the "virtual connection" inside the virtual train formation is disconnected; when the "virtual connection" is detected to be disconnected, it indicates that the formation relationship has failed, which is to say, an abnormal disassembly has occurred.

[0026] For example, if a train-to-train communication is interrupted during the operation of a virtual train formation, or if the integrity of a train in the virtual train formation is lost (due to a failure of the tail equipment), the virtual train formation will be abnormally disassembled.

[0027] In step S2, the train relative position acquisition and judgment module acquires the position status of the virtual train relative to the entrance signal S, and determines the position information as "the lead car 100 of the virtual train is approaching the entrance signal S" or "the lead car 100 of the virtual train has passed the entrance signal S". The train communication status acquisition and judgment module deployed in the RBC acquires and judges the communication status of the lead car 100 in the corresponding position status, and classifies the lead car into multiple downgraded train types according to the different communication statuses of the lead car 100, generates corresponding downgraded train information, and transmits it to the interlocking system.

[0028] If the communication status of the navigator 100 is "normal communication", the navigator 100 with "normal communication" is downgraded and identified as a "moving block train"; if the communication status of the navigator 100 is "interrupted communication", the navigator 100 with "interrupted communication" is downgraded and identified as a "non-communication train".

[0029] The downgraded train information includes: "Approaching moving block train", "Approaching non-communication train", "Crossing moving block train", and "Crossing non-communication train".

[0030] In step S3, the interlocking system executes corresponding control commands on the entry signal S based on the received various downgraded train information, and keeps the route locked until it is manually unlocked.

[0031] After receiving the downgraded train information from the RBC, the interlocking system no longer follows the original normal passage procedure for virtual train formations. Instead, it executes a pre-set safety control logic for abnormal train disassembly. The core of this logic is to ensure that signals do not erroneously display permission signals, that routes do not unlock abnormally, and to hand over the final unlocking authority to manual operation, thereby maintaining system availability while ensuring safety.

[0032] The following details the specific implementation process of steps S2 and S3 under different state combinations, taking into account specific situations.

[0033] Scenario 1: For example Figure 2 As shown, when the position of the virtual train relative to the entrance signal S is "the lead car 100 of the virtual train is approaching the entrance signal S, that is, the lead car 100 of the virtual train has not passed the entrance signal S," the virtual train has not yet entered the station throat area, and the entrance signal S remains open. Figure 1 This is a schematic diagram of the initial position of the virtual train formation according to the present invention, used as a reference diagram to clarify... Figure 2 The position shown is that the virtual train's lead car 100 is approaching the station entry signal S.

[0034] Sub-scenario 1.1: After decoupling, the lead car 100 has normal communication and is downgraded to a moving block train.

[0035] The train communication status acquisition and judgment module in the RBC sends a "moving block train approaching" message to the interlocking system. Upon receiving this message, the interlocking system controls the entry signal S to keep its first indicator light off (e.g., if the entry signal S is currently in a green light off state, it remains in that state). After the lead car 100 continues to run and passes the entry signal S, the train communication status acquisition and judgment module in the RBC sends a "moving block train crossing" message to the interlocking system based on the train position report. Upon receiving this message, the interlocking system controls the entry signal S to change its first indicator light from off to its second indicator light on (e.g., in this embodiment, changing the green light off to a red light on), and forcibly keeps the route in an unlocked state until the dispatcher performs a manual unlocking operation.

[0036] Sub-case 1.2: After decompilation, the navigator vehicle 100 loses communication and is determined to be a non-communication vehicle.

[0037] The train communication status acquisition and judgment module in the RBC sends a "non-communication car approaching" message to the interlocking system. Upon receiving this message, the interlocking system determines that the train has lost communication capability. To ensure operational safety, it switches the entry signal S from the virtual formation-specific "light off" mode to the regular display mode, setting the entry signal S to have its first indicator light on (e.g., green light on). When the lead car 100 passes the entry signal S, the train communication status acquisition and judgment module in the RBC sends a "non-communication car crossing" message to the interlocking system based on the train position report. The interlocking system, based on interlocking conditions such as track circuit occupancy checks, closes the permitted lighting state, controlling the entry signal S to change from its first indicator light to its second indicator light (at this point, the green light changes to red light), and forcibly keeps the route locked until manual unlocking.

[0038] Scenario 2: For example Figure 3 As shown, when the position status of the train relative to the entrance signal S is "the lead car 100 of the virtual train has passed the entrance signal S", the lead car 100 of the virtual train has entered the station throat area, and there is already a train occupying the area behind the entrance signal S.

[0039] Sub-scenario 2.1: After decoupling, the lead car 100 has normal communication and is downgraded to a moving block train.

[0040] The train communication status acquisition and judgment module in the RBC sends "moving block train crossing" information to the interlocking system. When the interlocking system receives this information, it continues to use the train communication status acquisition and judgment module to judge the communication status of the train 200 following the lead car 100 (i.e. the adjacent train following the lead car 100 in the opposite direction of travel), and downgrades the following train 200 to a moving block train or a non-communication car.

[0041] When the communication status of the following train 200 is "normal communication", it will be downgraded to a moving block train. The interlocking system will immediately set the second indicator light of the entrance signal S to turn off (i.e., set it to the red light off state) and forcibly keep the route locked until it is manually unlocked.

[0042] When the communication status of the following train 200 is "communication interrupted", it will be downgraded to a non-communication car. The interlocking system will immediately shut off the permission signal of the entrance signal S, that is, set the second indicator light of the entrance signal S to light up (i.e. set to red light state), and forcibly keep the route locked until it is manually unlocked.

[0043] Sub-case 2.2: After decompilation, the navigator vehicle 100 loses communication and is determined to be a non-communication vehicle.

[0044] The train communication status acquisition and judgment module in the RBC sends a "non-communication car crossing" message to the interlocking system. When the interlocking system receives this message, it immediately sets the second indicator light of the entry signal S to light up (i.e., sets it to red light status) and forcibly keeps the route locked until it is manually unlocked.

[0045] The present invention also provides a processing system for running the above-mentioned collaborative processing method. The system includes a monitoring module, a train relative position acquisition and judgment module, a train communication status acquisition and judgment module deployed in the RBC, and an interlocking system. The system achieves safety control in case of abnormal decoupling through the collaborative work of these modules.

[0046] The monitoring module is the system's sensing front end. It continuously monitors the operating status of the virtual train formation during its entry into the station, especially the integrity of the train-to-train communication link and the validity of the formation relationship. When an abnormal disassembly of the virtual train formation is detected, the module immediately triggers the subsequent processing procedures.

[0047] The train relative position acquisition and judgment module is communicatively connected to the entrance signal S. It is used to acquire the position status of the train relative to the entrance signal S and to determine the position information of "the lead car 100 of the virtual train is approaching the entrance signal S" or "the lead car 100 of the virtual train has passed the entrance signal S".

[0048] The train communication status acquisition and judgment module is deployed in the RBC. It is connected to the train relative position acquisition and judgment module and the monitoring module. It is used to acquire the communication status of the lead car 100 of the train in a specific position state (i.e., "the lead car 100 of the virtual train is approaching the entrance signal S" or "the lead car 100 of the virtual train has passed the entrance signal S") under abnormal disassembly conditions. Based on the different communication statuses of the lead car 100, the virtual train is divided into multiple downgraded train types and corresponding downgraded train information is generated.

[0049] If the train communication status acquisition and judgment module obtains that the communication status of the lead car 100 of the train at the specific position "the lead car 100 of the virtual train is approaching the station signal S" is "normal communication", then it is judged to be a downgraded "moving block train" and a "moving block train approaching" message is sent to the interlocking system; if the obtained communication status is "communication interrupted", then it is judged to be a downgraded "non-communication car" and a "non-communication car approaching" message is sent to the interlocking system.

[0050] If the train communication status acquisition and judgment module obtains that the communication status of the lead car 100 of the train after the specific position "the lead car 100 of the virtual train has passed the entry signal S" is "communication normal", then it is judged to be a downgraded "moving block train" and a "moving block train crossing" message is sent to the interlocking system; if the obtained communication status is "communication interrupted", then it is judged to be a downgraded "non-communication car" and a "non-communication car crossing" message is sent to the interlocking system.

[0051] In addition, the train communication status acquisition and judgment module is also used to acquire the communication status of the next adjacent train 200 of the lead car 100, and determine it as a downgraded moving block train or a non-communication train based on its communication status.

[0052] Upon receiving information such as "moving block train approaching," "non-communication train approaching," "moving block train crossing," or "non-communication train crossing," the interlocking system executes corresponding control commands on the entry signal S and keeps the route locked until manual unlocking, thereby locking the system's safety status and awaiting manual intervention.

[0053] In summary, the present invention provides a collaborative processing method and system for abnormal ungrouping of virtual trains, which can implement differentiated control strategies based on the different states of the ungrouped trains, and maintain the route until manual unlocking while ensuring safety.

The processing system as described in claim 9, characterized in that, The train communication status acquisition and judgment module performs the following judgment logic: If the train communication status acquisition and judgment module obtains that the communication status of the lead car at the position of "the lead car of the virtual train is approaching the station signal S" is "communication is normal", then it is judged to be a downgraded "moving block train" and "moving block train approaching" information is sent to the interlocking system. If the obtained communication status is "communication interrupted", it is determined to be a downgraded "non-communication vehicle" and a "non-communication vehicle approaching" message is sent to the interlocking system.

11. The processing system as described in claim 10, characterized in that, The train communication status acquisition and judgment module also performs the following judgment logic: If the train communication status acquisition and judgment module obtains that the communication status of the lead car at the position "the lead car of the virtual train has passed the entry signal S" is "communication normal", then it is judged to be a downgraded "moving block train" and the "moving block train crossing" information is sent to the interlocking system; If the obtained communication status is "communication interrupted", it is determined to be a downgraded "non-communication vehicle" and a "non-communication vehicle crossing" message is sent to the interlocking system.

12. The processing system as described in claim 9, characterized in that, The train communication status acquisition and judgment module is also used to acquire the communication status of the train following the lead train, and determine it as a downgraded moving block train or a non-communication train based on its communication status.
