Description

Technical Field

[0001] The present invention relates to the technical field of rail transit, and particularly to a method and system for protecting train moving authorization conflicts. Background Art

[0002] In a Communication Based Train Control System (CBTC system), moving authorization means that a train is authorized to enter and pass through a specific track section in a given running direction. The moving authorization is issued and supervised by a Zone Controller (ZC) before each communication cycle, and a Vehicle On-Board Controller (VOBC) executes the moving authorization to maintain a safe train interval and provide protection through a Computer Interlocking (CI).

[0003] In the prior art, for the moving authorization conflict protection method based on traditional route locking, when the ZC calculates the moving authorization for a train, it assigns moving authorizations to different trains according to the route direction arranged by the CI. The CI protects the opposing routes to ensure that the moving authorizations calculated by the ZC for different trains do not conflict. This moving authorization conflict protection method based on route locking is widely used in the CBTC system.

[0004] In the design scheme of a parking lot with flexible formation lines, the A garage and B garage of the parking lot are respectively designed as two different track sections to store two short-formation trains respectively, and operations such as automatic coupling and uncoupling are performed. Taking the design of the fully automatic operation parking lot on Beijing Subway Line 12 as an example, as Figure 1 shown, in order to achieve the flexible formation operation scenario, track circuit insulating joints are added to the A track in the garage, and the A track is divided into two different track sections, namely the A1 track and the A2 track, to store two different short-formation trains. When a train moves from the A2 track to the B track, the moving authorization needs to enter the B track through the A1 track. At this time, the condition for arranging a route for the A1 track is not available; when a train moves from the A1 track to the A2 track, the condition for arranging a route for the A2 track is not available. Therefore, the moving authorization conflict protection method based on route locking is no longer fully applicable in a fully automatic driverless system that can achieve the flexible formation function. Summary of the Invention

[0005] The train movement authorization conflict prevention method and system provided by the present invention are used to solve the above problems existing in the prior art, and solve the problem that the applicability of the prior art's movement authorization conflict prevention method based on traditional route locking to prevent train movement authorization conflicts is poor. By calculating the movement authorization of a second train running in the opposite direction to the first train through the section occupied by the first train movement authorization, and ensuring that the movement authorization of the second train cannot extend to the section occupied by the first train movement authorization, the prevention of movement authorization conflicts is achieved, and the applicability is high.

[0040] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0041] In the flexible formation operation scenario, the garage of the parking lot can store a long formation train or two short formation trains, and automatically perform operations such as coupling and uncoupling. Therefore, when designing the station yard, a garage is divided into 2 different track sections. When a train needs to move to another garage, there may be no available route in front of the train, and the movement authorization calculated by the ZC for the train needs to extend into the section without an available route. At this time, there may be other trains running in the opposite direction, and their movement authorizations also extend into this section, thus creating a risk of collision. Therefore, the traditional method of protecting against movement authorization conflicts based on route locking can no longer adapt to the flexible formation operation scenario. Based on this, the present invention proposes a method for protecting against movement authorization conflicts of trains to protect against conflicts of movement authorizations of different trains. The specific implementation is as follows:

[0042] Figure 2 It is one of the flow schematic diagrams of the method for protecting against movement authorization conflicts of trains provided by the present invention. As Figure 2 shown, the method includes:

[0043] Step 110, obtaining a first section occupied by a first train within a first movement authorization range;

[0044] Step 120, obtaining a second movement authorization of a second train, where the second train is a train running in the opposite direction to the first train, and the second movement authorization cannot extend to the first section.

[0045] It should be noted that the execution subject of the above method can be a computer device or the ZC. Below, the present invention will be described in detail with the ZC executing the above method.

[0046] In the embodiment of the present invention, the ZC calculates a first movement authorization for the first train and uses the section requisitioned within the first movement authorization range as the first section occupied within the first movement authorization range.

[0047] In the embodiment of the present invention, the first train can specifically be a single train or an entire train in a flexible formation train.

[0048] In an embodiment of the present invention, the first moving authorization range is the area between the starting point of the first moving authorization and the terminal, and the first moving authorization may specifically be the moving authorization of the first train.

[0049] In an embodiment of the present invention, the ZC calculates the second moving authorization for the second train. When the second train is a train running in the opposite direction to the first train, the second moving authorization cannot extend to the first section occupied within the first moving authorization range of the first train.

[0050] In an embodiment of the present invention, the second train may specifically be a train running in the opposite direction to the first train, and the train may specifically be a single train or an entire vehicle in a flexible formation train.

[0051] In an embodiment of the present invention, the second moving authorization may specifically be the moving authorization of the second train.

[0052] In an embodiment of the present invention, the flexible formation train may specifically be a formation train formed by coupling two trains, or a 4-formation train formed by coupling 4 trains, or an 8-formation train formed by coupling two 4-formation trains running in opposite directions. The present invention does not make specific limitations thereto.

[0053] In other embodiments of the present invention, the ZC calculates the second moving authorization for the second train. When the second train is a train running in the same direction as the first train, the second moving authorization is allowed to extend to the first section occupied within the first moving authorization range of the first train.

[0054] In other embodiments of the present invention, the second train may also specifically be a train running in the same direction as the first train, and the train may specifically be a single train or an entire vehicle in a flexible formation train.

[0055] For example, for the scenario of train depot relocating in a fully automated driverless flexible formation line parking lot, based on the above method, conflict prevention for the moving authorization of different trains can be achieved, solving the problem that the method for preventing moving authorization conflicts based on traditional route locking in the prior art is not applicable to the flexible formation operation scenario.

[0056] The method for preventing moving authorization conflicts of trains provided by the present invention solves the problem of poor applicability of the method for preventing moving authorization conflicts based on traditional route locking in the prior art. By calculating the moving authorization of the second train running in the opposite direction to the first train through the section occupied by the first train's moving authorization, and ensuring that the second train's moving authorization cannot extend to the section occupied by the first train's moving authorization, conflict prevention for the moving authorization is achieved, with high applicability.

[0057] Further, in one embodiment, when the first movement authorization retracts and the first train can stop before the end of the retracted first movement authorization, the method further includes:

[0058] Obtain the first requisition status of the first section;

[0059] Obtain the first area with the first requisition status being the occupied status, where the first area is the area within the range from the start point to the end point of the retracted first movement authorization;

[0060] Use the first area as the updated first section.

[0061] In the embodiment of the present invention, when the first movement authorization calculated by the ZC for the first train retracts, the ZC interacts with the first train, and when it is determined that the first train can stop before the end of the retracted first movement authorization, the ZC receives the first requisition status of the first section sent by the first train.

[0062] In the embodiment of the present invention, the first requisition status may specifically be the occupied status of the section within the first movement authorization, and the occupied status may specifically include the idle status and the occupied status.

[0063] In the embodiment of the present invention, the ZC uses the first area with the first requisition status being the occupied status as the first section occupied by the first train within the updated first movement authorization range.

[0064] In the embodiment of the present invention, the first area may specifically be the section occupied within the retracted first movement authorization range.

[0065] It should be noted that before the first movement authorization retracts, the requisition status within the first authorization range is all in the occupied status. When the ZC determines that the first movement authorization retracts and the first train can stop before the end of the retracted first movement authorization, the first requisition status of the first section includes the occupied status and the idle status. The occupied status is the requisition status of the area between the start point and the end point of the retracted first movement authorization, and the idle status is the requisition status of the area corresponding to the retracted part.

[0066] Further, in one embodiment, when the first movement authorization retracts and the first train cannot stop before the end of the retracted first movement authorization, the method further includes:

[0067] Obtain the second requisition status of the first section;

[0068] Obtain a second area where the second requisition status is the occupied status, and the second area is an area within the range from the starting point to the ending point of the first movement authorization;

[0069] Use the second area as the updated first section.

[0070] In an embodiment of the present invention, when the first movement authorization calculated by ZC for the first train retracts, ZC interacts with the first train, and when it is determined that the first train cannot stop before the ending point of the retracted first movement authorization, ZC receives the first requisition status of the first section sent by the first train.

[0071] In an embodiment of the present invention, the first requisition status may specifically be the occupied status of the sections within the first movement authorization.

[0072] In an embodiment of the present invention, ZC uses a second area where the first requisition status is the occupied status as the first section occupied by the first train within the updated first movement authorization range.

[0073] In an embodiment of the present invention, the second area may specifically be the occupied sections within the range from the starting point to the ending point of the first movement authorization.

[0074] It should be noted that before the first movement authorization retracts, the requisition statuses within the first authorization range are all in the occupied status. When ZC determines that the first movement authorization retracts and the first train cannot stop before the ending point of the retracted first movement authorization, the first requisition status of the first section still only includes the occupied status, and this occupied status is the requisition status of the area between the starting point and the ending point of the first movement authorization.

[0075] The train movement authorization conflict prevention method provided by the present invention solves the problem of poor applicability of the existing mobile authorization conflict prevention method based on traditional route locking to prevent train movement authorization conflicts. When the first movement authorization retracts, it can use the requisition status within the first movement authorization range to determine the section occupied by the first train's movement authorization, calculate the movement authorization for the second train running in the opposite direction to the first train based on this section, and prevent mobile authorization conflicts by ensuring that the movement authorization of the second train cannot extend to the section occupied by the first train's movement authorization, with high applicability.

[0076] Furthermore, in an embodiment, when the first movement authorization does not retract and the communication between the first train and the zone controller ZC is interrupted, the method further includes:

[0077] When the timing time of the ZC is greater than or equal to a preset threshold, obtain the third requisition status of the first section;

[0078] Obtain a third area whose third requisition status is the occupied status, where the third area is the area within the range from the starting point of the first movement authorization to the ending point of the first movement authorization, excluding the second section, and the second section is the section where the axle counter is in the idle state;

[0079] Use the third area as the updated first section.

[0080] In an embodiment of the present invention, when the first movement authorization calculated by the ZC for the first train does not retract, the ZC exchanges information with the first train. If it is found during the information exchange that the communication between the first train and the ZC is interrupted, the ZC receives the first requisition status of the first section sent by the first train. For example, if the ZC does not receive the information sent by the first train within a preset time, it means that the communication between the first train and the ZC is interrupted.

[0081] In an embodiment of the present invention, when the ZC determines that the first movement authorization does not retract and the communication between the first train and the ZC is interrupted, the ZC starts timing. When the timing time of the ZC is greater than or equal to the preset threshold, the ZC obtains the third requisition status of the continuously monitored first section.

[0082] In an embodiment of the present invention, the third requisition status may specifically be the occupied status of the section within the range from the starting point of the first movement authorization to the ending point of the first movement authorization, and the occupied status may specifically include the idle state and the occupied state.

[0083] In an embodiment of the present invention, the ZC uses the third area with the third requisition status of the occupied status as the first section occupied by the first train within the first movement authorization range.

[0084] In an embodiment of the present invention, the third area may specifically be the area within the range from the starting point of the first movement authorization to the ending point of the first movement authorization, excluding the second section. The second section may specifically be the section where the axle counter within the range from the starting point of the first movement authorization to the ending point of the first movement authorization has been cleared. After the axle counter is cleared, the axle counter is in the idle state, that is, the requisition status of the second section is the idle state.

[0085] In other embodiments of the present invention, when the ZC determines that the first movement authorization does not retract and the communication between the first train and the ZC is interrupted, the ZC starts timing. When the timing time of the ZC is greater than or equal to the preset threshold and the axle counters within the range from the starting point of the first movement authorization to the terminal of the first movement authorization are not cleared, the third area may also specifically be the area within the range from the starting point of the first movement authorization to the ending point of the first movement authorization.

[0086] Further, in one embodiment, when the first movement authorization does not retract and the first train loses communication with the Zone Controller (ZC), the method further includes:

[0087] When the timing time of the ZC is less than the preset threshold, obtain the fourth requisition status of the first section;

[0088] Obtain the fourth area with the fourth requisition status being the occupied status, where the fourth area is the area within the range from the start point to the end point of the first movement authorization;

[0089] Use the fourth area as the updated first section.

[0090] In the embodiment of the present invention, when the ZC determines that the first movement authorization does not retract and the first train loses communication with the ZC, it starts timing. When the timing time of the ZC is less than the preset threshold, the ZC obtains the fourth requisition status of the continuously supervised first section.

[0091] In the embodiment of the present invention, the fourth requisition status may specifically be the occupied status of the section within the range from the start point to the end point of the first movement authorization.

[0092] In the embodiment of the present invention, the ZC uses the third area with the fourth requisition status being the occupied status as the first section occupied by the first train within the first movement authorization range.

[0093] In the embodiment of the present invention, the fourth area may specifically be the occupied section within the range from the start point to the end point of the first movement authorization.

[0094] The train movement authorization conflict prevention method provided by the present invention solves the problem of poor applicability of the conventional train movement authorization conflict prevention method based on route locking in the prior art. When the first movement authorization does not retract and the first train loses communication with the ZC, it can use the requisition status within the first movement authorization range to determine the section occupied by the first train's movement authorization, calculate the movement authorization of the second train running in the opposite direction to the first train based on this section, and prevent movement authorization conflicts by ensuring that the movement authorization of the second train cannot extend to the section occupied by the first train's movement authorization, with high applicability.

[0095] Further, in one embodiment, when the first movement authorization retracts, before obtaining the first section occupied within the first movement authorization range of the first train, the method may specifically further include:

[0096] Based on the received first message, determine whether the first train can stop before the end of the retracted first movement authority. The first message is sent by the first train after receiving the second message sent by the ZC. The first message is used to indicate whether the first train can stop before the end of the retracted first movement authority. The second message is a message requesting the first train to stop before the end of the retracted first movement authority.

[0097] In an embodiment of the present invention, when the ZC determines that the first movement authority of the first train has retracted, it determines the expropriation status within the first movement authority through information interaction with the first train.

[0098] In an embodiment of the present invention, the ZC sends a second message to the first train, and the first train sends a first message to the ZC after receiving the second message sent by the ZC.

[0099] In an embodiment of the present invention, the second message may specifically be a message requesting the first train to stop before the end of the retracted first movement authority. The first message may specifically be a message in reply to the first message, and may specifically include relevant content on whether the first train can stop before the end of the retracted first movement authority.

[0100] For example, after the ZC is started, it is in an initialization state, and in this state, all sections are marked as idle. The ZC calculates the first movement authority for the first train in the "first come, first served" manner. When calculating the first movement authority, in addition to considering the controlled train status, running position, temporary speed limit command, rain and snow command, and full-line emergency braking command, it is also necessary to judge the expropriation status. After the ZC calculates the first movement authority for the first train, it marks all sections within the first movement authority of the first train as occupied, and then continuously monitors the expropriation status. If the first movement authority of the first train retracts, it sends a parking guarantee request (i.e., the second message) to the first train and judges the train's parking guarantee response (i.e., the first message). If the first train replies that it can stop before the end of the retracted first movement authority, the expropriation status of the retracted part can be changed to the idle state; if the first train replies that it cannot stop before the end of the retracted first movement authority, the sections of the retracted part remain occupied. If the communication between the ZC and the first train is interrupted, the ZC starts timing and makes a judgment after the timing ends: if the axle count where the section previously occupied by the first movement authority has cleared, the occupied status of the section can be released and changed to the idle state; if the axle count is in the occupied state, the occupied status of the section is maintained. After the ZC calculates the expropriation status in the above manner, when calculating the second movement authority for the second train, it is prohibited to extend into the section occupied by the first movement authority of the first train.

[0101] Figure 3It is the second schematic flow chart of the train movement authorization conflict prevention method provided by the present invention. As Figure 3 shown, the method may specifically include:

[0102] The ZC calculates the movement authorization for the first train and supervises the occupation status within the first movement authorization range;

[0103] If the first train movement authorization retracts, a stop guarantee request is sent to the first train, and the stop guarantee response is judged;

[0104] If the first train can stop before the end of the retracted first movement authorization, the occupation status of the retracted part is cleared and changed to the idle state;

[0105] If the train cannot stop before the end of the retracted first movement authorization, the occupation status of the retracted part is maintained;

[0106] If the communication between the ZC and the first train is interrupted, the ZC should start timing and make a judgment after the timing ends;

[0107] If the axle counter where the section requisitioned before the first movement authorization is cleared, the requisition status of the retracted part is released, and the requisition status requisitioned before the first movement authorization is changed to the idle state;

[0108] If the axle counter where the section requisitioned before the first movement authorization is occupied, the requisition status of the section is maintained as the occupied state.

[0109] When the ZC calculates the movement authorization for the second train, it cannot extend into the section occupied by the first train.

[0110] The train movement authorization conflict prevention method provided by the present invention can obtain the section occupied by the first movement authorization according to the real-time supervised requisition status within the first movement authorization range of the first train, and calculate the movement authorization for the second train running in the opposite direction to the first train through this section, and realize the prevention of movement authorization conflicts by ensuring that the movement authorization of the second train cannot extend to the section occupied by the first train movement authorization.

[0111] Next, the train movement authorization conflict prevention system provided by the present invention will be described. The train movement authorization conflict prevention system described below can be mutually corresponding and referred to with the train movement authorization conflict prevention method described above.

[0112] Figure 4 It is the structural schematic diagram of the train movement authorization conflict prevention system provided by the present invention. As Figure 4 shown, it includes:

[0113] The first acquisition module 410 and the second acquisition module 411;

[0114] The first acquisition module 410 is configured to acquire a first section occupied within a first movement authorization of a first train.

[0115] The second acquisition module 411 is configured to acquire a second movement authorization of a second train, where the second train is a train running in a direction opposite to that of the first train, and the second movement authorization cannot extend to the first section.

[0116] The train movement authorization conflict prevention system provided by the present invention solves the problem of poor applicability of the prior art in preventing train movement authorization conflicts by means of traditional route locking. By calculating the movement authorization of a second train running in the opposite direction to the first train based on the section occupied by the first train's movement authorization, and ensuring that the movement authorization of the second train cannot extend to the section occupied by the first train's movement authorization, the prevention of movement authorization conflicts is achieved, with high applicability.

[0117] Figure 5 It is a schematic physical structure diagram of an electronic device provided by the present invention. As Figure 5 shown, the electronic device may include: a processor 510, a communication interface 511, a memory 512, and a bus 513. Among them, the processor 510, the communication interface 511, and the memory 512 communicate with each other through the bus 513. The processor 510 can call logical instructions in the memory 512 to execute the following methods:

[0118] Acquire a first section occupied by a first train within a first movement authorization range;

[0119] Acquire a second movement authorization of a second train, where the second train is a train running in a direction opposite to that of the first train, and the second movement authorization cannot extend to the first section.

[0120] In addition, when the logical instructions in the above-mentioned memory are implemented in the form of software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium. Based on such an understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product. The computer software product is stored in a storage medium and includes several instructions for causing a computer power supply screen (which may be a personal computer, a server, or a network power supply screen, etc.) to execute all or part of the steps of the methods described in the various embodiments of the present invention. The aforementioned storage medium includes: various media such as USB flash drives, mobile hard disks, read-only memories (ROMs), random access memories (RAMs), magnetic disks, or optical discs that can store program codes.

[0121] Furthermore, the present invention discloses a computer program product. The computer program product includes a computer program stored on a non-transitory computer-readable storage medium. The computer program includes program instructions. When the program instructions are executed by a computer, the computer can execute the train movement authorization conflict prevention method provided in each of the above method embodiments, for example, including:

[0122] Obtain a first section occupied by a first train within a first movement authorization range;

[0123] Obtain a second movement authorization of a second train, where the second train is a train running in the opposite direction to the first train, and the second movement authorization cannot extend to the first section.

[0124] On the other hand, the present invention also provides a non-transitory computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, it is implemented to execute the train movement authorization conflict prevention method provided in each of the above embodiments, for example, including:

[0125] Obtain a first section occupied by a first train within a first movement authorization range;

[0126] Obtain a second movement authorization of a second train, where the second train is a train running in the opposite direction to the first train, and the second movement authorization cannot extend to the first section.

[0127] The system embodiments described above are merely illustrative. The units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed to multiple network units.
