Description

Technical Field

[0001] This application relates to the field of rail transit control technology, and in particular to a method and device for aligning and isolating coupled trains and platforms. Background Technology

[0002] In urban rail transit operations, platform screen doors are one of the key pieces of equipment for ensuring safety. Especially on driverless, fully automated lines, the signaling system needs to automatically control the opening and closing of platform screen doors according to preset conditions.

[0003] To balance the demand for transport capacity during peak passenger flows, the energy waste during low passenger flows, and the level of operational service (such as operating intervals), some urban lines have begun to adopt flexible train formation schemes. For example, 4-car trains are used during off-peak hours, while 4+4 trains or other combinations are used to increase capacity during peak hours. The coupled trains have four control terminals, but only one control terminal is used for train operation. The coupling methods for flexible train formations are diverse. Taking the coupling of one end of train A and train B as an example, it may be coupled through one end of train A and one end of train B, or it may be coupled through one end of train A and two ends of train B. Traditional fixed-formation trains have relatively simple methods for isolating faulty car doors and platform doors. However, due to the diverse coupling methods of flexible-formation trains, traditional isolation methods cannot meet their complex requirements. Summary of the Invention

[0004] This application provides a method and device for aligning and isolating coupled trains and platforms, aiming to solve the problem that traditional alignment and isolation methods cannot meet the complex needs of flexible train formation.

[0005] Firstly, this application provides a method for aligning and isolating a coupled train with a platform, comprising: Determine the sequence numbering of the first door of the coupled train; In response to a train entering and stopping at a station, based on the train's direction of travel, the locomotive information of the coupled train, and the relative position of the coupled train and the platform, the second door number sequence on the door opening side is extracted from the first door number sequence; The isolation door number in the second door number sequence is determined based on the faulty platform door number on the platform side and its own faulty car door number. In response to a door opening signal, the door corresponding to the isolation door number is isolated, while other doors on the door opening side are authorized to open.

[0006] In one embodiment, the isolation door number in the second door number sequence is determined based on the faulty platform door number on the platform side and its own faulty car door number, specifically including: The faulty platform door number on the receiving platform side; Based on the alignment relationship between the second door number sequence and the platform door number sequence, the faulty platform door number is mapped to the corresponding door number. The set of all door fault numbers and corresponding door numbers is used as the isolation door number.

[0007] In one embodiment, determining the sequence of the first door numbers of the coupled train specifically includes: The overall coupling information is determined by combining the first partial coupling information provided by multiple first train automatic protection systems in the coupled train; the first partial coupling information of each first train automatic protection system indicates the train group number, car group number, end position and coupling end information of the first train automatic protection system; the overall coupling information indicates the coupling method of multiple coupled train groups, including the arrangement order of multiple coupled train groups and the two end positions of the coupling between adjacent coupled train groups. Based on the end positions and arrangement order, the third door numbering sequences of all coupled trains are arranged to form the first door numbering sequence.

[0008] In one embodiment, before determining the overall coupling information by combining the first partial coupling information provided by multiple first train automatic protection systems within the coupled train, the method further includes: Determine whether each group is in a linked state; If a group is in a linked state, then the group is the linked group.

[0009] In one embodiment, determining whether each group is in a linked state specifically includes: By combining the second partial coupling information of multiple second train automatic protection systems in the train formation, it can be determined whether the train formation is in a coupled state; The second partial coupling information of the second train automatic protection system indicates the coupling information at the end where the second train automatic protection system is located.

[0010] In one embodiment, determining whether each group is in a linked state specifically includes: In the event of communication interruption or data anomaly, the status of the marshalling group is determined based on the hard-wire connection status.

[0011] Secondly, this application also provides a positioning isolation device between a coupled train and a platform, comprising: The first sequence determination module is used to determine the sequence of the first door numbers of the coupled train; The second sequence determination module is used to extract the second door number sequence on the door opening side from the first door number sequence in response to the train entering and stopping at the station, based on the train's running direction, the locomotive information of the coupled train, and the relative position of the coupled train and the platform. The isolation door determination module is used to determine the isolation door number in the second door number sequence based on the faulty platform door number on the platform side and its own faulty door number; The door isolation module is used to isolate the door corresponding to the isolation door number in response to the door opening signal, while authorizing other doors on the door opening side to open.

[0012] Thirdly, this application also provides a method for aligning and isolating coupled trains and platforms, including: After a train arrives at the station, the isolation platform door number is determined based on its own faulty platform door number and the faulty door number of the coupled train. In response to the door opening signal, the platform door corresponding to the isolation platform door number is isolated, while the normal platform door is allowed to open.

[0013] Fourthly, this application also provides a positioning isolation device between a coupled train and a platform, comprising: The platform screen door identification module is used to determine the platform screen door number after a train enters and stops at the station, based on its own faulty platform screen door number and the faulty door number of the coupled train. The platform door isolation module is used to isolate the platform door corresponding to the isolation platform door number in response to the train door opening signal, while allowing normal platform doors to open.

[0014] Fifthly, this application also provides an electronic device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements any of the above-described methods for aligning and isolating coupled trains with the platform. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] It should be noted that, in the description of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0020] The following is combined Figures 1 to 5 This application describes the alignment and isolation method and device for coupled trains and platforms.

[0021] It should be noted that the alignment and isolation method between coupled trains and platforms provided in this application embodiment is based on the alignment and isolation device between coupled trains and platforms. The alignment and isolation method between coupled trains and platforms can automatically identify the door number of the coupled train and confirm the door number sequence on the door opening side after accurately aligning it with the platform door. On this basis, based on the fault information interaction results between the train automatic protection system and the platform side, fault isolation is performed on all platform doors and train doors at fault locations during the door opening stage. This solves the fault isolation control problem in multi-group coupled scenarios, improves the safety and reliability of the fully automatic driving system, and reduces delays caused by misalignment between train doors and platform doors, thus optimizing train scheduling.

[0022] This application describes the alignment and isolation method between coupled trains and platforms using the alignment and isolation device of coupled trains and platforms as an example.

[0023] Figure 1 This is one of the flowcharts illustrating the alignment and isolation method between the coupled train and the platform provided in this application. For example... Figure 1 As shown, the alignment and isolation method between the coupled train and the platform provided in this application is applicable to the Automatic Train Protection (ATP) system of the coupled train, and the method includes: S110: Determine the sequence number of the first door of the coupled train.

[0024] A coupled train consists of multiple coupled carriages. Each carriage consists of multiple carriages arranged in a fixed order. Understandably, the order of the carriages in a carriage can be set at the factory.

[0025] Each carriage has multiple doors on both sides. For each train set, the doors on each side are numbered according to the door sequence of the carriages. For example, in a train set with four carriages (i.e., a 4-car set), each carriage has five doors. Therefore, from end 1 to end 2 of the train set, the door numbering sequence on the first side is A11, A12, A13, A14, A15, A21...A25, A31...A35, A41...A45. The door numbering sequence on the second side is B11, B12, B13, B14, B15, B21...B25, B31...B35, B41...B45.

[0026] When multiple train sets are coupled together, different coupling methods will result in different door numbering sequences on the coupled train. For example, the door numbering sequence after coupling end 1 of the first train set and end 2 of the second train set will be different from the door numbering sequence after coupling end 1 of the first train set and end 1 of the second train set. Therefore, it is necessary to determine the first door numbering sequence based on the arrangement order of the coupled train sets and the position of the coupling ends.

[0027] S120: In response to a train entering and stopping at a station, based on the train's direction of travel, the locomotive information of the coupled train, and the relative position of the coupled train and the platform, extract the second door number sequence on the door opening side from the first door number sequence.

[0028] Both ends of a coupled train can serve as the locomotive. When the train's direction of travel and its relative position to the platform are the same, different locomotive positions result in different door opening sides, i.e., different second door numbering sequences. Specifically, the relative position of the coupled train to the platform refers to whether it stops on the left or right side of the platform. Even with the same train direction of travel and locomotive information, stopping on different sides of the platform results in different door opening sides, i.e., different second door numbering sequences. Even with the same locomotive information and relative position to the platform, different train directions result in different door opening sides, i.e., different second door numbering sequences.

[0029] Based on the above, the door numbering sequence on the door-opening side may differ depending on the combination of train travel direction, the position of the locomotive of the coupled train, and the relative position of the coupled train to the platform. Therefore, it is necessary to determine the second door numbering sequence on the door-opening side according to the specific combination.

[0030] S130: Determine the isolation door number in the second door number sequence based on the faulty platform door number on the platform side and its own faulty car door number.

[0031] In this step, the Automatic Train Protection System (ATPS) needs to obtain information on all malfunctioning platform screen doors and their corresponding train doors, as well as all malfunctioning train doors and their corresponding platform screen doors. Specifically, the malfunctioning platform screen doors can only be obtained by the APS interacting with the Platform Screen Door Controller (PSC) on the platform side.

[0032] S140: In response to a door opening signal, isolate the door corresponding to the isolated door number, and at the same time authorize the opening of other doors on the door opening side.

[0033] During the door opening phase, the train's automatic protection system isolates the corresponding doors of all malfunctioning platform doors and all malfunctioning doors. At the same time, the platform door controller isolates the corresponding platform doors of all malfunctioning doors and all malfunctioning platform doors, ensuring that platform doors and doors in all malfunctioning positions do not open, while platform doors and doors in normal positions can be opened (the normal positions here do not include doors in coupled trains that are preset to never be checked).

[0034] This application embodiment automatically identifies the door numbers of coupled trains and confirms the door number sequence on the door opening side after precise alignment with the platform doors. Based on this, and using the fault information interaction results between the train automatic protection system and the platform side, fault isolation is performed on all platform doors and train doors at fault locations during the door opening phase. This solves the fault isolation control problem in multi-train coupled scenarios, improves the safety and reliability of the fully automatic driving system, and reduces delays caused by misalignment between train doors and platform doors, thus optimizing train scheduling.

[0035] In one possible implementation, step S110, determining the sequence of the first door numbers of the coupled train, specifically includes: S1110: Determine the overall coupling information by combining the first partial coupling information provided by multiple first train automatic protection systems within the coupled train.

[0036] Before coupling, each train set has an automatic train protection system at both ends 1 and 2, which communicate and synchronize information with each other. Each end's automatic train protection system stores its own train set number, car group number, and its own end position.

[0037] After coupling, all automatic safety systems (AHS) of all trains in all trainsets become the first AHS of the coupled train. All first AHS systems in a coupled train can communicate and synchronize information with each other. Each first AHS system can send its own trainset number, car group number, end position, and coupling partner information (i.e., first partial coupling information) to other first AHS systems. The end position of a first AHS system refers to whether it is located at end 1 or end 2 of its own trainset. The coupling partner information of a first AHS system includes the trainset number, car group number, and end position of the other trainset end coupled to the end of its own trainset.

[0038] Therefore, each first train automatic protection system can acquire the first partial coupling information of all first train automatic protection systems, and then summarize these first partial coupling information to obtain the overall coupling information. The overall coupling information indicates the coupling method of multiple coupled train groups, including the arrangement order of the multiple coupled train groups and the two end positions of the coupling between adjacent coupled train groups.

[0039] Please combine Figure 2 Taking the coupling of two train groups, A and B, as an example, the coupling method might be: One end (A1) of group A is connected to one end (B1) of group B, forming a combination of A2-A1-B1-B2; One end (A1) of group A is connected to the other end (B2) of group B, forming a combination of A2-A1-B2-B1; The two ends (A2) of group A are connected to the two ends (B2) of group B to form a combination of A1-A2-B2-B1; The two ends (A2) of group A are connected to the one end (B1) of group B, forming a combination of A1-A2-B1-B2.

[0040] S1120: Arrange the third door number sequences of all coupled trains according to their end positions and arrangement order to form the first door number sequence.

[0041] The first door numbering sequence includes two door numbering sequences, representing the numbering order of the doors on both sides of the coupled train. Figure 2 Taking the combination A2-A1-B1-B2 as an example, the sequence of the first door numbers closest to the platform is B45, B44, B43, B42, B41, B35......B31, B25......B21, B15......B11, A11, A12, A13, A14, A15, A21......A25, A31......A35, A41......A45. The sequence of the first door numbers furthest from the platform is A45, A44, A43, A42, A41, A35......A31, A25......A21, A15......A11, B11, B12, B13, B14, B15, B21......B25, B31......B35, B41......B45.

[0042] This application embodiment summarizes the partial coupling information of all train automatic protection systems on the coupled train to obtain the overall coupling information of the coupled train. Based on the overall coupling information, the door number sequence of the coupled train is obtained. The coupling information is determined through real-time communication between the train automatic protection systems to ensure the accuracy of the door numbers.

[0043] In one possible implementation, before determining the overall coupling information by combining the first partial coupling information provided by multiple first train automatic protection systems within the coupled train (S1110), the following steps are also included: Determine whether each group is in a linked state. If a group is in a linked state, then the group is the linked group.

[0044] Since this application targets a flexible train formation scheme, each train formation needs to monitor its own coupling status in real time to determine whether it is part of a coupled train, thus providing the basic conditions for establishing a connection between the automatic train protection system in the train formation and the automatic train protection system of other train formations.

[0045] In one possible implementation, determining whether each group is in a linked state specifically includes: By combining the second partial coupling information of multiple second train automatic protection systems in the train formation, it is determined whether the train formation is in a coupled state.

[0046] Among them, the second partial coupling information of the second train automatic protection system indicates the coupling information at the end where the second train automatic protection system is located.

[0047] Based on the above, each train set has a second automatic train protection system at both ends 1 and 2, which communicate and synchronize with each other. Each second automatic train protection system can obtain the coupling status of its own end, i.e., the second local coupling information, through input / output (I / O) interface signals. This second local coupling information indicates whether its own end is connected to another train set. Specifically, it can determine its own coupling status by receiving electrical signals from coupler connection sensors or signals from mechanical coupling switches through the I / O interface. Simultaneously, each second automatic train protection system can receive coupling status information from another second automatic train protection system within the same train set. Any second automatic train protection system can determine whether its own train set is in a coupled state by summarizing the coupling statuses at both ends, i.e., whether one or both ends of its train set are coupled to other train sets.

[0048] This application embodiment uses the coupling status information of the train automatic protection system at both ends of the train to determine whether the train is in a coupled state, and summarizes the local information into the overall information, which can ensure the accuracy of the status information.

[0049] In one possible implementation, determining whether each group is in a linked state also includes: In the event of communication interruption or data anomaly, the status of the marshalling group is determined based on the hard-wire connection status.

[0050] In the event of communication interruption or data anomaly, the automatic protection systems at both ends of the train cannot communicate and cannot obtain the coupling status of the automatic protection system at the other end. At this time, each automatic protection system can directly receive the coupling status signal transmitted from the physical line (such as relay contacts) to obtain the coupling status of its own train, without relying on the coupling status signal of the communication bus.

[0051] This application embodiment ensures the accuracy of coupling status information through a fault-tolerant mechanism. The automatic train protection system can determine whether the coupling platform has been changed based on the current hardline information, thereby ensuring the accurate alignment of the train doors and platform doors and the implementation of fault isolation strategies, ensuring that the system can still maintain basic operational safety under abnormal conditions.

[0052] Based on the above, in step S120, when the train enters and stops at the station, the Automatic Train Protection System obtains the train's running direction through the positioning system. Combining this with the pre-configured current locomotive information and the platform side (left or right) where the coupled train is stopped, it extracts the second door number sequence from the first door number sequence, specifically selecting the first door number sequence closer to the platform side as the second door number sequence. This conversion process ensures a perfect spatial match between the train door and the platform door.

[0053] This application embodiment combines the running direction, stopping information, and train head information to achieve precise alignment between the platform door and the train door.

[0054] In one possible implementation, step S130 involves determining the isolation door number in the second door number sequence based on the faulty platform door number on the platform side and the faulty car door number of the car itself. Specifically, this includes: S1310: Faulty platform door number on the receiving platform side.

[0055] In one possible implementation, the automatic train protection system interacts with the platform door controller on the platform side to exchange the faulty platform door number and the faulty train door number.

[0056] S1320: Based on the alignment relationship between the second door number sequence and the platform door number sequence, map the faulty platform door number to the corresponding door number.

[0057] The automatic train protection system determines the car door number corresponding to the faulty platform door number based on the alignment relationship between the platform door and the car door, and uses this number as the alignment car door number.

[0058] S1330: The set of all door fault numbers and corresponding door numbers is used as the isolation door number.

[0059] The automatic safety system of coupled trains can only authorize the opening and closing of doors. Therefore, the automatic safety system collects information on doors that need to be isolated.

[0060] This application embodiment uses the train automatic protection system and the platform door controller for vehicle-to-ground communication to convert the faulty car door number into the corresponding platform door number and send it to the platform side, or to convert the faulty platform door number into the corresponding car door number, thereby obtaining all fault information of the platform door and car door. This provides accurate information for subsequent fault isolation, ensuring that no matter whether the car door or the platform door malfunctions, the platform door and car door at that location will not be opened, ensuring the safety of train operation and avoiding the adverse effects caused by passenger congestion at the faulty door location.

[0061] In one possible implementation, step S130, which determines the isolation door number in the second door number sequence based on the faulty platform door number on the platform side and its own faulty car door number, further includes: Based on the alignment relationship between the second door number sequence and the platform door number sequence, the fault number of its own door is mapped to the corresponding platform door number. Send the platform door number to the platform side.

[0062] In this embodiment, the automatic train protection system actively maps the faulty door information to the corresponding platform door information, directly providing the platform door controller with the platform door that needs to be isolated corresponding to the faulty door, thereby improving the interaction information and operational efficiency between the two.

[0063] Based on the above, in step S140, in response to the door opening signal, the door corresponding to the isolation door number is isolated, while other doors on the door opening side are authorized to open.

[0064] Specifically, when a train door or platform door malfunctions, the automatic safety system automatically initiates an isolation procedure while ensuring the operational function of the normal doors. This process is fully automated, requiring no manual intervention, significantly improving response speed and safety.

[0065] Specifically, please combine Figure 2 and Figure 3 The platform screen door numbering sequence is fixed for all trains on the line, with the numbers reversed on both sides. Taking a train with 5 doors per car as an example, after two 4-car trains are coupled together, there are a total of 40 doors, and 41 platform screen doors. Door No. 21 is only opened when there is a single 4-car train. When the trains are coupled together, there is no corresponding door at the coupling end of the train, so platform screen door No. 21 is not opened.

[0066] like Figure 2 As shown, taking the A1-A2-B2-B1 coupling configuration as an example, assume the train stops on the left side of the platform while running on the main line. At this time, the platform door on the left side needs to be opened. Assuming that doors B33 of both train A and train B malfunction, the automatic train protection system determines that door B33 of train B is the right-side door based on the second door number sequence and does not need to be opened after stopping. Door B33 of train A is the left-side door, and after stopping, its corresponding platform door is door number 29, which needs to be opened. At this time, the fault information for B33 of train A is sent to the platform side. During the door opening phase, the automatic train protection system isolates B33 of train A, and the platform side simultaneously isolates door number 29; neither opens.

[0067] Based on the above, this application also provides a positioning isolation device for coupled trains and platforms. The positioning isolation device for coupled trains and platforms can be referred to in correspondence with the aforementioned positioning isolation method for coupled trains and platforms.

[0068] As an example, such as Figure 4 As shown, the alignment isolation device between the coupled train and the platform provided in this application is applicable to the ATP system of coupled trains, and the device includes: The first sequence determination module 410 is used to determine the sequence of the first door numbers of the coupled train.

[0069] The second sequence determination module 420 is used to extract the second door number sequence on the door opening side from the first door number sequence in response to the train entering and stopping at the station, based on the train's running direction, the locomotive information of the coupled train, and the relative position of the coupled train and the platform.

[0070] The isolation door determination module 430 is used to determine the isolation door number in the second door number sequence based on the faulty platform door number on the platform side and its own faulty door number.

[0071] The door isolation module 440 is used to isolate the door corresponding to the isolation door number in response to the door opening signal, while authorizing other doors on the door opening side to open.

[0072] This application embodiment automatically identifies the door numbers of coupled trains and confirms the door number sequence on the door opening side after precise alignment with the platform doors. Based on this, and using the fault information interaction results between the train automatic protection system and the platform side, fault isolation is performed on all platform doors and train doors at fault locations during the door opening phase. This solves the fault isolation control problem in multi-train coupled scenarios, improves the safety and reliability of the fully automatic driving system, and reduces delays caused by misalignment between train doors and platform doors, thus optimizing train scheduling.

[0073] Based on the above, this application also provides a method for aligning and isolating coupled trains and the platform on the platform side, including: P1: After the train arrives at the station, the isolation platform door number is determined based on its own faulty platform door number and the faulty door number of the coupled train. Please refer to the explanation of step S130 above.

[0074] P2: In response to the door opening signal, isolate the platform door corresponding to the isolation platform door number, while allowing normal platform doors to open. Please refer to the explanation of step S130 above.

[0075] This application embodiment uses the train automatic protection system and the platform door controller for vehicle-to-ground communication to convert the faulty car door number into the corresponding platform door number and send it to the platform side, or to convert the faulty platform door number into the corresponding car door number, thereby obtaining all fault information of the platform door and car door. This provides accurate information for subsequent fault isolation, ensuring that no matter whether the car door or the platform door malfunctions, the platform door and car door at that location will not be opened, ensuring the safety of train operation and avoiding the adverse effects caused by passenger congestion at the faulty door location.

[0076] Based on the above, this application also provides a positioning isolation device suitable for coupled trains and the platform on the platform side, comprising: The platform screen door identification module is used to determine the platform screen door number after a train enters and stops at the station, based on its own faulty platform screen door number and the faulty door number of the coupled train. The platform door isolation module is used to isolate the platform door corresponding to the isolation platform door number in response to the train door opening signal, while allowing normal platform doors to open.

[0077] This application embodiment uses the train automatic protection system and the platform door controller for vehicle-to-ground communication to convert the faulty car door number into the corresponding platform door number and send it to the platform side, or to convert the faulty platform door number into the corresponding car door number, thereby obtaining all fault information of the platform door and car door. This provides accurate information for subsequent fault isolation, ensuring that no matter whether the car door or the platform door malfunctions, the platform door and car door at that location will not be opened, ensuring the safety of train operation and avoiding the adverse effects caused by passenger congestion at the faulty door location.

Figure 5 As shown, the electronic device may include: a processor 510, a communications interface 520, a memory 530, and a communication bus 540, wherein the processor 510, the communications interface 520, and the memory 530 communicate with each other via the communication bus 540. The processor 510 can call logical instructions in the memory 530 to execute a positioning isolation method between the coupled train and the platform, the method including: Determine the sequence numbering of the first door of the coupled train; In response to a train entering and stopping at a station, based on the train's direction of travel, the locomotive information of the coupled train, and the relative position of the coupled train and the platform, the second door number sequence on the door opening side is extracted from the first door number sequence; The isolation door number in the second door number sequence is determined based on the faulty platform door number on the platform side and its own faulty car door number. In response to a door opening signal, the door corresponding to the isolation door number is isolated, while other doors on the door opening side are authorized to open.

[0079] Furthermore, the logical instructions in the aforementioned memory 530 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.
