Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a parking control method and device for a virtual marshaled train entering a station, as well as a computer-readable storage medium and a train automatic operation control system. Background Art

[0002] Virtual marshaling technology differs from traditional physical train coupling. It typically involves virtually coupling multiple trains together, treating them as a single, integrated train. However, due to the insufficient length of some platforms, virtual marshaling trains cannot simultaneously enter and stop at the station. To address this, related technologies propose sequentially entering and stopping at the station for trains within a marshaling. Specifically, for the leading and trailing trains in two adjacent trains within a marshaling, the trailing train's front end stops at the platform's stop point after the leading train's rear end leaves the stop point. The disadvantage of this approach is that it doesn't take into account the actual platform conditions. If the platform is large enough to accommodate multiple trains simultaneously, stopping only one train at the station is inefficient. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, a first object of the present invention is to provide a parking control method for a virtual marshaling train entering a station, so as to improve the efficiency of the virtual marshaling train entering the station.

[0007] To achieve the above-mentioned purpose, a second embodiment of the present invention proposes a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the above-mentioned parking control method for a virtual train entering a station is implemented.

[0008] To achieve the above-mentioned purpose, the third aspect of the present invention proposes an automatic train operation control system, including: a virtual marshaling train and a parking control device for the virtual marshaling train entering the station, wherein the parking control device for the virtual marshaling train entering the station includes a memory, a processor and a computer program stored on the memory, and when the computer program is executed by the processor, the above-mentioned parking control method for the virtual marshaling train entering the station is implemented.

[0009] The parking control method for a virtual marshalling train entering a station, as well as the computer-readable storage medium and the train automatic operation control system of the embodiments of the present invention can obtain the train parameters of the virtual marshalling train and the platform parameters of the target platform, and then generate a parking strategy based on the train parameters and the platform parameters, thereby realizing the acquisition of a parking strategy based on the actual situation of the platform and the actual situation of the train to control the virtual marshalling train after parking, thereby improving the parking efficiency of the virtual marshalling train.

[0022] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0023] The following describes, with reference to the accompanying drawings, a method and device for controlling the parking of a virtual marshaled train entering a station, and a computer-readable storage medium and a train automatic operation control system according to embodiments of the present invention.

[0024] Figure 1 The present invention is a flowchart of a method for controlling the parking of a virtual train set entering a station according to an embodiment of the present invention.

[0025] In this embodiment, the virtual train set includes multiple trains set up and running on the same line. Figure 1 As shown in FIG, the parking control method for a virtual marshaling train entering a station includes:

[0026] S11, obtaining the train parameters of the virtual marshaled train and the platform parameters of the target platform.

[0027] Specifically, an automatic operation control system can be pre-established, comprising a parking strategy library pre-generation module, a parking strategy selection trigger module, a parking strategy selection module, a parking strategy dynamic generation module, and a parking point and door-opening car information distribution module. The automatic operation control system monitors the position of the lead car of the virtual train in real time. The parking strategy selection trigger module determines whether the virtual train needs to enter the station based on the position of the lead car. If the virtual train is determined to need to enter the station, the station is recorded as the target platform, and the train parameters of the virtual train and the platform parameters of the target platform are obtained.

[0028] S12, matching a parking strategy from a preset parking strategy library according to train parameters and platform parameters.

[0029] S13, if the matching is successful, the parking strategy is obtained from the parking strategy library; if the matching fails, the doors of the trains in the virtual marshaling train are aligned with the platform doors of the target platform according to the train parameters and platform parameters, and the parking strategy is obtained according to the alignment results of each train.

[0030] Specifically, after obtaining train and platform parameters, these are input into the parking strategy selection module, which then matches a parking strategy from the parking strategy library based on these parameters. If the match is successful, a parking strategy is retrieved from the parking strategy library. If the match is unsuccessful, the parking strategy dynamic generation module aligns the doors of the trains in the virtual train with the platform doors of the target platform based on the train and platform parameters. Based on the alignment results, a parking strategy is dynamically generated for each train. If the generation fails, an error message is displayed, indicating that the virtual train cannot enter the target platform for parking.

[0031] Among them, the parking strategy library pre-generation module can pre-acquire the train parameters of commonly used virtual marshaling trains and the platform parameters of all platforms, and then input the train parameters of the commonly used virtual marshaling trains and the platform parameters of all platforms into the parking strategy dynamic generation module to obtain a parking strategy library, so that when it is necessary to match the parking strategy according to the train parameters and platform parameters, it can be directly matched from the parking strategy library, thereby improving the efficiency of virtual marshaling trains entering the station. Moreover, after the parking strategy is dynamically generated according to the benchmarking results of each train, the parking strategy can also be saved to the parking strategy library, so that if the same virtual marshaling train needs to stop at the target platform in the future, the parking strategy can be directly matched from the parking strategy library. In this way, the parking strategy library can be continuously updated, thereby better improving the efficiency of virtual marshaling trains entering the station.

[0032] S14, performing parking control on the virtual train set according to the parking strategy.

[0033] Specifically, after obtaining the parking strategy, the above-mentioned parking point and door opening vehicle information sending module can, for example, send the parking strategy, each train entry time, and platform door opening information to the virtual train and the target platform through the interface, so as to control the parking of the virtual train.

[0034] In this way, the parking control of the virtual train can be achieved according to the train parameters of the virtual train and the platform parameters of the target platform, so as to obtain the parking strategy for the virtual train by utilizing the actual situation of the virtual train and the actual situation of the platform, thereby improving the parking efficiency of the virtual train.

[0035] In one embodiment of the present invention, the train parameters include at least the number of trains in the virtual train set, the body length of each train, the number of train sets, the minimum number of doors to be opened, and the minimum distance between trains. The platform parameters include at least the maximum range of the target platform allowed to stop and the position of each platform door of the target platform. Figure 2 , the above method aligns the doors of the trains in the virtual marshaling train with the platform doors of the target platform according to the train parameters and platform parameters, and obtains the parking strategy based on the alignment results of each train, including:

[0036] S21, according to the number of trains, select trains from the virtual train set in order.

[0037] S22, for each selected train, align the doors and platform doors of the selected train according to the body length, number of train formations, minimum number of doors to be opened, minimum distance from the preceding vehicle, maximum range of parking allowed at the target platform, and position of the platform door of the target platform.

[0038] S23, obtaining the parking sub-strategy of the selected train based on the benchmarking result, wherein the parking sub-strategy includes the parking batch, parking position and door opening information of the selected train, and the parking sub-strategies of all trains in the virtual train constitute the parking strategy.

[0039] Specifically, if no parking strategy is matched from the preset parking strategy library, the train parameters are obtained, and the number of trains is obtained based on the train parameters, and then trains are taken in sequence from the virtual train set according to the number of trains. For example, if a virtual train set includes N trains, after obtaining the number of trains, since there is no train assigned to enter the station in the virtual train set, that is, the N trains are all trains that have not been assigned to enter the station, the first train of the N trains is taken in sequence to enter the station; and then after the train is assigned to enter the station, since there are still N-1 trains that have not been assigned to enter the station, the first train of the N-1 trains is taken in sequence to enter the station; and then after the train is assigned to enter the station, since there are still N-2 trains that have not been assigned to enter the station, the second train of the N-2 trains is taken in sequence to enter the station; and so on, until all the above-mentioned N trains are assigned to enter the station. It should be noted that, see Figure 3 During the process of sequentially retrieving trains, if after retrieving a certain train, the next train fails to be retrieved, for example, if the Hth train has been retrieved and the H+1th train fails to be retrieved, the system checks whether the number of trains not assigned to the station is 0. If so, the parking strategy is considered to have been generated successfully, and the parking strategy can be issued. If not, the train retrieval interface is abnormal and the parking strategy generation failure is reported.

[0040] When selecting trains in sequence, trains are selected starting with the first train and their doors and platform doors are aligned. If the first train in a virtual train formation cannot be aligned with the platform door of the target platform, an error message is generated, warning that the virtual train formation cannot enter the station and stop. If, after one train has successfully aligned with the platform door, another train fails to align with the platform door of the target platform, the trains that have been scheduled to enter the station are considered a parking batch, and the parking batch when this situation first occurs is the first parking batch. The number of trains in the first parking batch is the maximum number of trains allowed to stop at the target platform for this virtual train formation. For example, if a virtual train formation includes 6 trains, and there are 2 trains in the target platform when the target platform is saturated, then the 1st train and the 2nd train in the virtual train formation are the 1st parking batch, the 3rd train and the 4th train are the 2nd parking batch, the 5th train and the 6th train are the 3rd parking batch, and the maximum allowed number of parkings at the target platform for the virtual train formation is 2.

[0041] It should be noted that in the process of picking up trains in sequence, it is necessary to select the corresponding benchmarking method based on whether the picked up train is the first car of the current parking batch. After obtaining the benchmarking method corresponding to the picked up train, the benchmarking method corresponding to the picked up train is used to benchmark the doors and platform doors of the picked up train based on the body length, number of trains, minimum number of doors opened, minimum distance between the car and the preceding car, as well as the maximum range allowed for parking at the target platform and the platform door position of the target platform, so as to obtain the parking sub-strategy corresponding to the picked up train and realize the allocation of the train into the station.

[0042] Specifically, the above-mentioned marking method corresponding to the lead car is: if the train taken is the lead car of the current parking batch, then according to the minimum number of doors opening D1 of the lead car, the lead car is marked to the D1 platform doors farthest from the target platform in the direction of entry, and the head of the lead car is judged according to the body length of the lead car whether the front of the lead car exceeds the maximum range allowed for parking; if it exceeds, the marking is determined to have failed, and the minimum number of doors opening of the lead car is increased by 1, and the lead car is marked to the D1+1 platform doors farthest from the target platform in the direction of entry, and the marking check and re-marking process are repeated until the marking is successful.

[0043] The above-mentioned marking method corresponding to non-leading cars is as follows: if the selected train is not the leading car of the current parking batch, then based on the body length of the selected train and the minimum distance between it and the car in front, it is judged whether there are any remaining platform doors that can be marked at the target platform; if there are no remaining platform doors, the selected train will be marked as the leading car of the next parking batch; if there are remaining platform doors, then based on the minimum distance between the selected train and the car in front and the minimum number of doors opened D2 of the selected train, the selected train will be marked to the D2 platform doors farthest in the target platform's remaining entry direction that can be marked, and based on the body length of the selected train, it is judged whether the rear end of the selected train exceeds the maximum range allowed for parking; if it exceeds, the selected train will be marked as the leading car of the next parking batch; if it does not exceed, then the number of doors that can be opened of the selected train will be determined based on the number of train formations and the number of remaining platform doors that can be marked at the target platform, and the parking position of the selected train will be obtained based on the marking position of the selected train. Among them, the minimum value between the number of train formations and the number of remaining platform doors that can be matched at the target platform can be selected as the number of doors that can be opened on the train. The above number of formations is the number of doors on the train.

[0044] It should also be noted that when the train taken is the head car of the current parking batch, before the head car is aligned with the D1 platform doors farthest in the target platform's entry direction according to the minimum number of doors opening D1 of the head car, it is also necessary to determine that the number of trains not assigned to enter the station in the virtual train set is greater than or equal to the maximum allowable number of stops for the target platform; among them, if the number of trains not assigned to enter the station in the virtual train set is less than the maximum allowable number of stops for the target platform, then the parking sub-strategy of each train not assigned to enter the station is obtained based on the body length, number of trains, minimum spacing distance, and maximum allowable parking range and platform door position of the trains not assigned to enter the station.

[0045] Specifically, after determining the maximum number of stops allowed for the target platform for the virtual train set based on the first stop batch, it is first possible to determine whether the number of trains not assigned to enter the station is greater than or equal to the maximum number of stops. If not, this indicates that the number of remaining trains not assigned to enter the station is less than the maximum number of stops allowed for the virtual train set at the target platform. A parking sub-strategy can be assigned to the remaining trains not assigned to enter the station according to the preset train entry rules, such as ensuring that the last train can successfully align with the platform door closest to the target platform's approach direction. Based on this, the remaining trains not assigned to enter the station are aligned according to the body length, number of trains, and minimum spacing of the trains not assigned to enter the station before the last train. Therefore, compared to still aligning the lead train with the platform door farthest from the target platform's approach direction, the parking sub-strategy obtained in this way can shorten the entry time of the trains in the last stop batch.

[0046] Optionally, if the number of trains not assigned to enter the station is greater than or equal to the maximum number of stops, the trains with the maximum allowed number of stops can be directly selected from the remaining trains not assigned to enter the station starting from the first train and used as a parking batch, and this parking batch directly uses the parking sub-strategy of the first parking batch.

[0047] In this way, it is possible to obtain the parking sub-strategy of each train in the virtual train formation, and thus obtain the parking strategy of the virtual train formation according to the parking sub-strategy of each train.

[0048] In one embodiment of the present invention, see Figure 4 Before obtaining the train parameters of the virtual marshalling train and the platform parameters of the target platform, the parking control method for the virtual marshalling train entering the station also includes: obtaining the head position of the leading car of the virtual marshalling train in real time; determining the trigger area where the head position of the leading car of the virtual marshalling train reaches the target platform, wherein the trigger area is an area within a preset distance range from the target platform before the virtual marshalling train enters the station.

[0049] Specifically, a certain area before the platform's approach for each station direction can be pre-determined as a trigger zone for virtual train parking strategy selection. The parking strategy selection trigger module detects the position of the lead car in the virtual train in real time and determines whether the leading car's front end has reached a specific parking strategy selection trigger zone. If the leading car's front end reaches a trigger zone, the platform corresponding to that trigger zone is selected as the target platform. Furthermore, a matching parking strategy can be determined in the parking strategy library. If so, the matching parking strategy is issued; if not, a dynamic strategy is generated.

[0050] In this way, it is possible to determine whether the virtual marshaling train needs to enter the station.

[0051] In one embodiment of the present invention, two adjacent parking lots are recorded as the front lot and the back lot, see Figure 5 The above-mentioned parking control of the virtual train according to the parking strategy includes:

[0052] S51: After the first batch of trains starts to depart from the target platform, the first train of the second batch will be able to align with the nearest platform door in the direction of entry to the target platform, and then the trains of the second batch will be controlled to start entering the station.

[0053] S52, wait for the tail of the last car of the front batch to leave the parking position of the first car of the rear batch, control the trains of the rear batch to stop at the corresponding parking position of the target platform, and control the corresponding train doors of the trains of the rear batch to open.

[0054] As an example, see Figure 6,It can be seen that after the virtual marshalling train is ,controlled by parking strategy, multiple trains can stop at the target ,platform at the same time, thereby improving the ,entry efficiency of the virtual marshalling train.

[0055] It should be noted that before controlling the subsequent batches of trains to stop at the corresponding parking positions of the target platform, it is also necessary to execute the preset train entry rules to control the subsequent batches of trains to enter the station, as shown in the following example: Figure 7 As shown:

[0056] S71, wait for the trains of the next batch to arrive at the platform door that was last aligned, and determine whether the trains of the next batch can be aligned to the corresponding next platform door.

[0057] S72: If yes, control the subsequent batch of trains to continue entering the station until they reach the corresponding parking position.

[0058] S73: If not, the trains in the following batches are controlled to slow down to maintain the corresponding minimum interval distance. When they can align with the corresponding next platform door, the trains in the following batches are controlled to continue entering the station.

[0059] In this way, it is possible to control the virtual train group's entry and parking according to the parking strategy. If the number of trains in the latter batch is less than the number of trains in the former batch, the latter batch of trains can be assigned a parking sub-strategy according to the above-mentioned preset train entry rules.

[0060] Optionally, if the number of trains in the latter batch is the same as that in the former batch, the latter batch can directly use the parking sub-strategy of the former batch and then enter the station according to the above-mentioned preset train entry rules.

[0061] The parking control method for a virtual marshaled train entering a station according to an embodiment of the present invention is described in detail below with reference to a specific example.

[0062] In this specific example, see Figure 8, the virtual train consists of three trains with two marshaling groups, that is, there are three trains in the virtual train, and each train has two doors on one side. In the process of selecting trains in sequence, the first train T1 in the virtual train is first selected. This first train T1 is the head car of the current parking batch, and then the doors and platform doors of this train are aligned according to the alignment method corresponding to the head car. If the alignment is possible, the second train T2 in the virtual train is then sequentially selected. First, the doors and platform doors of this train are aligned according to the alignment method corresponding to non-head cars, and then it is determined whether the second train T2 will be the head car of the next parking batch based on the alignment method corresponding to non-head cars. If it is not the first car of the next parking batch, the third train T3 in the virtual train is taken in sequence. First, the doors and platform doors of the train are aligned according to the alignment method corresponding to non-first cars, and then it is determined whether the third train T3 is the first car of the next parking batch based on the alignment method corresponding to non-first cars. If it is not the first car of the next parking batch, trains T1, T2, and T3 are controlled to enter the station at the same time. The rear door of train T1 is opened and the front door is closed. The front and rear doors of train T2 are both opened. The front door of train T3 is opened and the rear door is closed. The platform doors P1, P2, P3, and P4 are opened at the same time. In this way, the platform utilization rate is maximized and the operational efficiency is improved.

[0063] The parking control method for a virtual marshaled train entering a station according to an embodiment of the present invention will be described in detail below with reference to another specific example.

[0064] In this specific example, see Figure 9, the virtual train consists of three trains with two marshaling groups, that is, there are three trains in the virtual train, and each train has two doors on one side. In the process of selecting trains in sequence, the first train T3 in the virtual train is first selected. The first train T3 is the head car of the current parking batch, and then the doors and platform doors of the train are aligned according to the alignment method corresponding to the head car. If the alignment is possible, the second train T2 in the virtual train is then sequentially selected. The doors and platform doors of the train are first aligned according to the alignment method corresponding to non-head cars, and then it is determined whether the second train T2 is the head car of the next parking batch based on the alignment method corresponding to non-head cars. If it is not the lead car in the next stop batch, the third train T1 in the virtual train is sequentially selected. The doors and platform doors of this train are first aligned using the alignment method corresponding to non-lead cars. This alignment method is then used to determine whether this third train T1 is the lead car in the next stop batch. If it is the lead car in the next stop batch, the first train T3 and the second train T2 are considered to be in the first stop batch, and the maximum number of stops allowed at the target platform for this virtual train is 2. The third train T1 in the virtual train is then sequentially selected and assigned a parking sub-strategy according to the preset train entry rules.

[0065] Furthermore, the first batch of trains arrives first. Train T2's front and rear doors are both open. Train T3's front door is closed, its rear door is open, platform doors P1, P2, and P4 are open, and platform door P3 is closed. When the first batch of trains departs the platform, the pre-set train arrival rules are implemented. Specifically, the platform door availability is checked in real time. If the front door of train T1 can align with platform door P1, then T1 begins arriving. If T1 arrives at the platform door P1, it will check whether the platform door P2 is vacant and the minimum train interval can meet the requirements for T1 to align with the platform door P2. If so, T1 will continue to enter the station and run to the platform door P2 and stop. At this time, the front and rear doors of the T1 train can be opened, and the platform doors are P1 and P2. If the former condition is not met, T1 will slow down and maintain the minimum train interval distance. When the platform door P2 can be aligned, T2 will run to the platform door P2 and stop. The front and rear doors of the T1 train will be opened, and the platform doors are P1 and P2.

[0066] In summary, the parking control method for a virtual marshalling train entering a station according to an embodiment of the present invention can obtain the train parameters of the virtual marshalling train and the platform parameters of the target platform, and then generate a parking strategy based on the train parameters and the platform parameters, thereby realizing the acquisition of a parking strategy based on the actual conditions of the platform and the actual conditions of the train to control the virtual marshalling train after parking, thereby improving the parking efficiency of the virtual marshalling train and reducing the waiting time of passengers.

[0067] Furthermore, the present invention provides a computer-readable storage medium.

[0068] In an embodiment of the present invention, a computer program is stored on a computer-readable storage medium. When the computer program is executed by a processor, the above-mentioned parking control method for a virtual marshaled train entering a station is implemented.

[0075] Furthermore, the present invention proposes a train automatic operation control system.

[0076] Figure 11 It is a structural block diagram of the automatic train operation control system according to an embodiment of the present invention.
