Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a method, device, equipment and storage medium for determining a virtual train marshaling operation diagram. Background Art

[0002] Train operation diagrams are key technical documents in railway and subway operations, guiding the operation planning, organization, control and adjustment of trains. With the increase in urban transportation demand, especially during peak hours, the capacity scheduling of trains has become more complex and important. Traditional train operation diagrams usually rely on physical coupling technology to increase capacity by physically connecting two trains together. However, this physical coupling method has many limitations, such as requiring additional time for coupling and uncoupling operations, affecting the turnover efficiency of trains and increasing operating costs. To address these issues, the industry has introduced virtual coupling technology. Virtual coupling technology enables trains to operate in coordination without physical connection, allowing trains to maintain independent operating lines but be dispatched as a whole in operation. This technology has greatly improved the operating efficiency of trains, especially during peak hours, and can flexibly adjust train formations to cope with changes in instantaneous passenger flow.

[0003] However, the existing virtual coupling technology still has certain problems. The traditional method lacks efficient and accurate methods in the process of identifying and updating virtual coupling status information, resulting in the inability of traditional train operation diagrams to accurately describe the operating conditions under virtual coupling, making it difficult for dispatchers to effectively manage the operation of virtual coupling trains, increasing the complexity and difficulty of dispatching.

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the long-term train dispatching and operation process, the applicant found that with the growing demand for urban rail transit, especially during peak hours, traditional physical coupling technology has gradually exposed many problems. Although physical coupling technology can increase capacity by physically connecting two trains together, this method requires extra time to complete coupling and uncoupling operations, which directly affects the turnover efficiency of the train and increases operating costs. At the same time, the applicant also found in the research process that the flexibility and response speed of physical coupling technology in scheduling are significantly limited when facing a complex operating environment, making it difficult to meet the needs of modern urban transportation.

[0025] In order to meet these challenges, the industry has introduced virtual coupling technology, which achieves coordinated operation between trains by eliminating physical connections, improving operational efficiency to a certain extent. However, in further research, the applicant found that the existing virtual coupling technology still has shortcomings in the application process. Traditional train operation diagrams are difficult to accurately describe the operation status of trains under virtual coupling, especially in the process of identifying and updating train coupling status information, there is a lack of efficient and accurate methods. This problem makes dispatchers face higher complexity and difficulty in managing the operation of virtual coupling trains, and they cannot give full play to the advantages of virtual coupling technology.

[0026] In view of the above problems, the present invention proposes the following embodiments.

[0027] Figure 1 FIG. 1 is a flow chart of a method for determining a virtual train marshaling diagram provided by the present invention, such as Figure 1 As shown, the method includes the following: Step 110, based on the reversing relationship information in the initial operation diagram, determine the train information of each train with the same reversing relationship; wherein, the operation routes of each train with the same reversing relationship are the same.

[0028] Here, the reversal relationship information refers to the arrangement and information of the train's reversal operation during operation; for example, reversing from a terminal station to the starting station, or switching to another line after arriving at a station. This information determines the time and method of the train's reversal.

[0029] It should be noted that virtual coupling technology allows trains to operate in coordination without physical coupling. In order to effectively dispatch trains in a virtual coupling state on the running line, it is necessary to ensure that these trains belong to the same turnaround relationship. This ensures that they are consistent in turnaround arrangements and times, making the scheduling coordination under the virtual coupling state more accurate. When two trains are on the same running line, these trains will pass through the same stations along the same path, that is, the order of the stations passed is consistent. Virtual coupling technology is only applicable to trains on the same running line, because they need to follow the same station order, which is the basic condition to ensure that the trains are coupled.

[0030] Here, the train information of each train may include the operation data of the corresponding train on the operation line, such as the platform number, the arrival and departure time of the corresponding train at each station, etc.

[0031] Exemplarily, when the dispatcher performs coupling-related operations on the operation diagram, the method starts to obtain train information of the same return relationship as the data basis for subsequently determining the coupling operation diagram.

[0032] like Figure 2 As shown, Figure 2 The data structure of the initial run graph is shown.

[0033] Exemplarily, the data structure of the initial operation diagram includes the turnaround relationship information. Each train under the same turnaround relationship has its own train information, and the train information of each train includes the station information of each station it will pass through next. The station information includes the station code, arrival time, departure time, and the coupling information and uncoupling information newly added to this scheme: the coupling information includes the coupling mark, coupling track, and coupling train number; the uncoupling information includes the uncoupling mark, uncoupling track, and uncoupling train number.

[0034] like Figure 3 As shown, Figure 3 A schematic diagram of the turnaround of Train A is shown.

[0035] For example, in the initial operation diagram, the specific expression of the return relationship information is as follows: Figure 3 As shown, after train A completes the turnaround operation at the terminal, it is updated to A', and trains A and A' constitute the turnaround relationship information.

[0036] Step 120: Determine the first train and the second train in a virtual coupling state based on the train information of each of the trains.

[0037] Here, virtual coupling means that the trains are treated as a whole in scheduling and management. Although they are not physically connected, they will be treated as a whole in the operation diagram. This state allows the trains to coordinate in timetable and scheduling to improve capacity and efficiency.

[0038] It should be noted that the train information of each train includes detailed information of each station on the running route of the train, such as arrival time and departure time, etc. Since the train information of each train is under the same turnaround relationship, and the running routes of each train in the same turnaround relationship are the same, the order of stations passed by each train is consistent, that is, each train passes through the same stations, and the difference is the arrival time and departure time of each train at each station.

[0039] In one embodiment, detailed information of each station of each train on the running line is determined based on the train information of each train, and then based on the departure time of each train at the same station, the first train and the second train in the virtual coupling state are determined.

[0040] The specific method for determining the virtual coupled train based on the departure time of each train at the same station can be referred to the following embodiment, which will not be described in detail here.

[0041] Step 130: Based on the coupling information determined by the virtual coupling state, the train information of the first train and the train information of the second train in the initial operation diagram are updated to determine the coupling operation diagram.

[0042] Here, the coupling information includes but is not limited to coupling marks, coupling tracks, coupling train numbers, coupling target stations, etc. The coupling operation diagram refers to the updated operation diagram, which accurately reflects the actual operation arrangement of the trains in the virtual coupling state.

[0043] In one embodiment, according to the coupling information, the train information of the first train and the second train in the initial operation diagram is adjusted, and the train information of the first train and the train information of the second train are updated to reflect their operation conditions in the virtual coupling state, thereby determining the coupling operation diagram.

[0044] The specific method for updating the train information of the first train and the train information of the second train can be referred to the following embodiments, which will not be elaborated here.

[0045] The method for determining a virtual train marshaling operation diagram provided by an embodiment of the present invention can identify a first train and a second train in a virtual coupling state through train information of each train in the same reversing relationship; accurately update the train information of the first train and the second train in the initial operation diagram through the coupling information, thereby reconstructing the coupling operation diagram, which can accurately reflect the train operation status under the virtual coupling condition; ensure that the trains are independent but coordinated in actual operation, which can be clearly displayed on the operation diagram, so that dispatchers can manage them intuitively and efficiently; by accurately describing the train operation status under the virtual coupling state, dispatchers can dispatch and manage more efficiently and reduce the possibility of misoperation.

[0046] Based on any of the above embodiments, in the method, determining the first train and the second train in a virtual coupling state based on the train information of each of the trains includes: Traversing the train information of each train; each train information includes the departure time point of the corresponding train at each station on the running line; Based on the departure time point of each train at each station on the running line, determining the interval between the departure time points of each train at the same station; If the interval duration is less than a preset coupling duration threshold, the two trains corresponding to the two exit time points forming the interval duration are marked as a virtual coupling state, and the first train and the second train in the virtual coupling state are determined.

[0047] Here, the departure time point refers to the specific time when the train leaves a certain station, which is important data for analyzing the train operation schedule.

[0048] Here, the interval time refers to the time difference between the departure times of two trains at the same station, which is used to determine whether the two trains may be in a virtual coupling state.

[0049] Here, the preset coupling time threshold is a set time threshold used to determine whether two trains are in a coupling state. If the interval between the departure time points of the two trains is less than this value, it is considered that they may be in a virtual coupling state.

[0050] In one embodiment, the train information of all trains under the same reversing relationship is traversed, and the information of each train includes the exit time points of each station on the running line; further, in the traversal process, the exit time of each train at the same station is compared, and the interval time points are calculated, and this interval time reflects the time difference between the two trains leaving the same station; further, the calculated interval time is compared with the preset coupling time threshold, if the interval time is less than the threshold, it means that the time when the two trains leave the same station is very close, and they are running in coordination in a virtual coupling state, and therefore, the two trains are marked as being in a virtual coupling state; through the above analysis, it is determined which two trains are in the virtual coupling state, and they are marked as the first train and the second train.

[0051] The method for determining the virtual train marshaling operation diagram provided by the embodiment of the present invention can accurately identify trains running in a virtual coupling state by accurately calculating the differences in the departure time points of trains at various stations. This method reduces the possibility of misjudgment and improves the efficiency of the dispatching system; after determining the virtual coupled trains, the operation diagram can be adjusted more effectively, and the dispatching and resource allocation of trains can be optimized, especially during peak hours, and can flexibly respond to changes in passenger flow; by automatically identifying virtual coupled trains, the system can make adjustments quickly, improving operational efficiency and dispatching response speed.

[0052] Based on any of the above embodiments, in the method, based on the coupling information determined by the virtual coupling state, the train information of the first train and the train information of the second train in the initial operation diagram are updated to determine the coupling operation diagram, including: Based on the interlocking information determined by the virtual interlocking state, determining the interlocking target station; the interlocking target station is the station for determining the virtual interlocking state; Based on the connection target station, determining a first subsequent station information set in the train information of the first train, and determining a second subsequent station information set in the train information of the second train; The first subsequent station information set includes the station information of each station of the first train located after the target station for connection in the running route; the second subsequent station information set includes the station information of each station of the second train located after the target station for connection in the running route; Based on the interlocking information, the first subsequent station information set and the second subsequent station information set are updated to determine an interlocking operation diagram.

[0053] It should be noted that the target station for coupling refers to the station where the virtual coupling operation occurs, and is the key starting point for updating the operation diagram. After the virtual coupling operation is performed at the target station for coupling, the two trains in the coupling state will operate in the coupling state in the subsequent operation.

[0054] Here, the first subsequent station information set refers to the station information set of the subsequent stations that the first train passes on the running route and is located after the coupling target station after the coupling operation. The station information of each subsequent station includes the train's arrival time, departure time and station code, etc.; this information needs to be adjusted after coupling to ensure the coordination of train operation. The second subsequent station information set refers to the station information set of the subsequent stations that the second train passes on the running route and is located after the coupling target station.

[0055] It should be noted that since the first train and the second train run on the same route, their subsequent stations are also the same. However, the difference is that the specific contents of the station information of each subsequent station are different, such as the arrival time and departure time. The existence of these differences requires corresponding adjustments to the information after coupling to ensure the coordination of train operation and the consistency of the plan.

[0056] The method for determining the train virtual marshaling operation diagram provided in an embodiment of the present invention can accurately adjust the train operation plan after coupling by determining the coupling target station based on the coupling information determined based on the virtual coupling state, and determining the subsequent station information set after the coupling target station for the first train and the second train respectively. Specifically, this method ensures that after the coupling operation, the two trains can operate in a coordinated and consistent manner according to the updated operation diagram while sharing the same operating line. This not only improves the flexibility of train scheduling, but also ensures the punctuality rate and operating efficiency of the train, and effectively solves the problem that the traditional operation diagram cannot accurately describe the operation of the train in the virtual coupling state.

[0057] Based on any of the above embodiments, in this method, each station information in the first subsequent station information set includes the departure time of the first train at the corresponding station, and each station information in the second subsequent station information set includes the departure time of the second train at the corresponding station; The updating of the first subsequent station information set and the second subsequent station information set based on the connection information includes: Adding the connection information to each station information in the first subsequent station information set and each station information in the second subsequent station information set respectively; The departure time point of the first train in each station information in the first subsequent station information set and the departure time point of the second train in each station information in the second subsequent station information set are updated to ensure that the interval duration between the departure time points of the first train and the second train at the same station is less than a preset coupling duration threshold.

[0058] Here, the coupling information is added to the station information of the first train and the second train at each subsequent station, which ensures that the station information of each subsequent station reflects the coupling status of the trains.

[0059] Exemplarily, the coupling information may include but is not limited to coupling marks, coupling tracks, coupling train numbers, and coupling target stations. By adding coupling marks to the station information of subsequent stations, the running status of trains after coupling can be better tracked and managed to ensure that the coupled trains run according to the predetermined plan. The addition of coupling tracks and coupling train numbers can ensure that during the operation of subsequent stations, trains run in the correct order on the same track, reducing confusion and misoperation during the scheduling process. Synchronizing these coupling information in the subsequent station information can ensure that all relevant stations and operators can obtain the latest coupling status in a timely manner, reducing misunderstandings and operational errors.

[0060] It should be noted that the departure times of the first train and the second train recorded in their respective subsequent station information sets are adjusted to ensure that the time interval between the two trains leaving the same station is less than the preset coupling time threshold. This adjustment is to ensure that in the virtual coupling state, the departure times of the two trains at each station are close enough to maintain the synchronization of the coupling operation.

[0061] The method for determining the virtual train marshaling operation diagram provided by the embodiment of the present invention timely updates the subsequent station information of the first train and the second train through the coupling information determined based on the virtual coupling state, so that the coupling operation diagram can accurately reflect the actual operation of the train after coupling. Specifically, by identifying the coupling target station, it can be clear at which station the train starts the coupling operation, which lays the foundation for the subsequent operation plan adjustment; after the coupling target station, the operation information of the first train and the second train needs to be synchronized and adjusted to ensure the coordination and consistency of the two trains during the driving process after coupling; the updated operation diagram can more accurately guide the operation of the train in the coupling state, improve the accuracy of scheduling, and reduce uncertainty and errors in operation.

[0062] Based on any of the above embodiments, in the method, after updating the train information of the first train and the train information of the second train in the initial operation diagram based on the coupling information determined based on the virtual coupling state and determining the coupling operation diagram, the method further includes: If the interval between the exit time points of the first train and the second train at the same station is greater than the preset coupling time threshold, determining that the first train and the second train are changed from a virtual coupling state to a decoupling state; Determine a demixing target station based on the demixing information determined by the demixing state; the demixing target station is the station for which the demixing state is determined; Based on the de-marshalling target station, selecting the station information of each station after the de-marshalling target station from the first subsequent station information set as a first de-marshalling subsequent station information set; selecting the station information of each station after the de-marshalling target station from the second subsequent station information set as a second de-marshalling subsequent station information set; Based on the de-marshalling information, the first de-marshalling subsequent station information set and the second de-marshalling subsequent station information set are updated to determine a de-marshalling operation diagram.

[0063] Here, the disassembly state refers to the state in which two trains change from the virtual coupling state to the independent operation state during operation. The disassembly target station refers to the station where the disassembly operation is performed after the two trains change from the virtual coupling state to the disassembly state.

[0064] It should be noted that the first disassembly subsequent station information set refers to the station information after the disassembly target station selected from the first subsequent station information set; that is, the first disassembly subsequent station information set includes the station information of all stations after the disassembly target station, which is used to update the operation diagram after disassembly to ensure that the train can accurately reflect the operation arrangement in the independent operation after disassembly. The second disassembly subsequent station information set refers to the station information after the disassembly target station selected from the second subsequent station information set.

[0065] In one embodiment, it is first determined whether the interval time between the exit time points of a first train and a second train at the same station is greater than a preset coupling time threshold; if the interval time exceeds this threshold, it means that the two trains cannot continue to maintain a close coupling state in the subsequent journey, and therefore it is necessary to change their state from virtual coupling to a decoupling state; further, after determining the decoupling state, the station where the decoupling operation occurs, that is, the decoupling target station, is identified, which is an important node for the train to resume independent operation; further, starting from the decoupling target station, respective decoupling subsequent station information sets are generated for the first train and the second train, that is, the first decoupling subsequent station information set and the second decoupling subsequent station information set; finally, based on the decoupling information, the first decoupling subsequent station information set and the second decoupling subsequent station information set are updated to determine the decoupling operation diagram.

[0066] The method for determining the train virtual marshaling operation diagram provided by the embodiment of the present invention determines that when the interval time between the exit time points of the first train and the second train is greater than the preset coupling time threshold, their states are changed from virtual coupling to de-marshaling state, so that the independent operation state of the train after de-marshaling can be correctly processed, thereby avoiding inaccurate scheduling or operation conflicts caused by the time interval of the coupling state exceeding the threshold; further, the de-marshaling target station is determined based on the de-marshaling state, and the station information after the de-marshaling target station is selected from the first subsequent station information set and the second subsequent station information set to form the first de-marshaling subsequent station information set and the second de-marshaling subsequent station information set. This process ensures that in the operation of the train after de-marshaling, the operation information of the subsequent station, including the arrival time and the exit time, can be accurately obtained and updated, ensuring that the independent operation of the train can be carried out according to the new timetable; finally, based on the de-marshaling information, the first de-marshaling subsequent station information set and the second de-marshaling subsequent station information set are updated to determine the de-marshaling operation diagram. This not only improves the accuracy of train scheduling, but also optimizes operation management, and reduces the scheduling complexity and potential operation problems caused by the change of virtual coupling state.

[0067] Based on any of the above embodiments, in the method, updating the first demultiplexing subsequent station information set and the second demultiplexing subsequent station information set based on the demultiplexing information includes: Clearing the connection information of each station information in the first decompilation subsequent station information set and the connection information of each station information in the second decompilation subsequent station information set; The departure time point of each station information of the first train in the first disassembly subsequent station information set and the departure time point of each station information of the second train in the second disassembly subsequent station information set are updated to ensure that the interval duration between the departure time points of the first train and the second train at the same station is greater than the preset coupling time threshold.

[0068] It should be noted that after the train is disassembled, the previously recorded virtual coupling information is no longer applicable, so it is necessary to clear these coupling information from the first disassembly subsequent station information set and the second disassembly subsequent station information set. The purpose of this step is to ensure that the information of the train after disassembly is no longer affected by the virtual coupling state, thereby avoiding misoperation and information conflicts. The departure time point of the second train at each station in the second disassembly subsequent station information set is also updated. The purpose of the update is to ensure that the departure time point interval of the two trains at each station meets the new scheduling requirements, that is, to ensure that after disassembly, their departure time interval is greater than the preset coupling time threshold.

[0069] For example, Figure 4 As shown, Figure 4 The table shows the entire process of Train 101 and Train 102 going from their independent states to virtually coupling at Station A, turning back at Station C, and then decoupling at Station B. It should be noted that the train numbers of Train 101 and Train 102 change after the turnaround, but the coupling state of the two does not change. Among them, ① is the departure time of Train 101 after virtual coupling, ② is the departure time of Train 102 after coupling, ③ is the departure time of Train 202 after decoupling, and ④ is the departure time of Train 201 after decoupling.

[0070] Specifically, Station A is the target station for coupling, and Station B is the target station for uncoupling. When Train 101 and Train 102 are coupled at Station A, it is necessary to traverse the train information of Train 101 and the train information of Train 102. Based on the coupling information, the first subsequent station information set and the second subsequent station information set are determined from the train information of Train 101 and the train information of Train 102; that is, the first subsequent station information set includes the station information of 101 at Station B, Station C, Station B after turning back, and Station C after turning back, which is more accurate. Specifically, the station information of station B after the turnaround includes the information such as the departure time of train 101; and the second subsequent station information set includes the station information of 102 at station B, station C, station B after the turnaround, and station C after the turnaround. More specifically, the station information of station B after the turnaround includes the information such as the departure time of train 102; when the interval between the departure time of train 101 and train 102 at station B after the turnaround is greater than the preset coupling time threshold, it is considered that train 101 and train 102 are uncoupled. The preset coupling time threshold can be set to 5 seconds.

[0071] The method for determining the train virtual marshaling operation diagram provided in an embodiment of the present invention can effectively handle the information synchronization problem after the train is disassembled by clearing the coupling information after disassembly and updating the train's departure time point. Clearing the coupling information ensures that in the disassembly state, it is no longer affected by the previous virtual coupling state, thereby avoiding scheduling conflicts or errors caused by outdated coupling information. Updating the departure time point ensures that the train can meet the new scheduling requirements after disassembly, especially ensuring that the departure time interval between trains is greater than the preset coupling time threshold. This measure helps to optimize the operational scheduling of trains, reduce potential time conflicts, improve operational efficiency, and reduce the risk of misoperation due to inaccurate information, thereby improving the reliability and scheduling accuracy of the overall system.
