Description

Technical Field

[0001] The present disclosure belongs to the technical field of railway control, and particularly relates to a turnout control method, system, device and medium for virtual formation trains. Background Art

[0002] Compared with the existing CTCS train control system or CBTC train operation control system, the train operation control system based on virtual formation has become a current research hotspot and future development direction due to its flexible transport organization and high operation efficiency.

[0003] Turnout control is an important function of the signal system. After the turnout is locked, it cannot be rotated arbitrarily, and it can only be operated after the train that has requisitioned it clears the turnout area, so as to ensure the safety of trains passing through the turnout area. A virtual formation train consists of multiple train units and can be regarded as a single train during operation. In order to ensure that the train formation can pass through the turnout smoothly, the existing method is to manage the turnout resources by applying exclusive locks, shared locks, etc. to the turnout, so as to ensure that the turnout will not be requisitioned by other trains when the virtual formation train formation passes through the turnout. However, in this way, the virtual formation train formation always remains as a whole, and the formation of the train formation does not change. If the virtual formation is uncoupled and reorganized, it is also a feasible way, but this way is less efficient.

[0004] The transport organization method of virtual formation trains is relatively flexible, and using turnouts to change the formation of virtual formation trains is a common method. Therefore, how to efficiently control and manage turnouts to adapt to the changes in virtual formation is a problem. Disadvantages of the existing technical solutions:

[0005] 1. It cannot meet the requirements for changes in the formation of virtual formation train formations in the turnout area;

[0006] 2. It cannot meet the efficiency requirements for changes in the formation of virtual formation train formations in the turnout area.

[0007] Therefore, it is necessary to provide a new turnout control method, system, device and medium for virtual formation trains to solve the above technical problems. Summary of the Invention

[0008] The purpose of the present disclosure is to provide a turnout control method, system, device and medium for virtual formation trains to solve the above problems.

[0009] The present disclosure achieves the above purpose through the following technical solutions:

[0010] A turnout control method for virtual formation trains includes the following steps:

[0011] Determine the head vehicle of the virtual formation train among the leading vehicles of multiple train formations, and sort the trains in the current train formation according to priority;

[0012] Issue the train operation plan to the leading vehicle of each train formation;

[0013] Plan the train operation path for each train formation, predict the time for each train to pass through each turnout, and send the path information to the leading vehicle of each train formation;

[0014] Apply for first-level locking and the attached time to the turnout, and send the train information to pass and the priority information of each train to the turnout;

[0015] Control the leading vehicle of each train formation to apply for second-level locking to the turnout. After the second-level locking is successful for the train, the train passes within the specified time;

[0016] Calculate the passing time of the train formation passing through the turnout, and complete the second-level locking of each train according to the train priority;

[0017] Make the virtual formation train pass through the turnout.

[0018] As a further optimized solution of the present disclosure, trains with the same departure time can be grouped into a virtual formation train to be formed. The train priorities include the highest priority, high priority, medium priority, and low priority; the leading vehicle has the highest priority; trains with the same destinations as the leading vehicle at the next two stops have high priority; trains with the same destination as the leading vehicle at the next stop and different destinations from the leading vehicle at the second stop have medium priority; trains with different destinations from the leading vehicle at the next stop have low priority.

[0019] As a further optimized solution of the present disclosure, the train operation plan includes the departure time, destination, and train information in the train formation.

[0020] As a further optimized solution of the present disclosure, the attached time is a time period based on the train departure time, considering the time for the train to run to the turnout, the turnout rotation and locking, and the time for the train to pass, until it completely exits the turnout area or the station.

[0021] As a further optimized solution of the present disclosure, the first-level locking is that the leading vehicle of the determined virtual formation train locks the original leading vehicles of each train formation within the virtual formation train. After the first-level locking, only the leading vehicle of the virtual formation train within the whitelist can apply for locking to the turnout within the attached time.

[0022] As a further optimized solution of the present disclosure, the second-level locking is that the leading vehicle of each train formation applies for locking to the turnout. The locking method is the leading vehicle locking of the train formation, including train formation locking and single vehicle locking. Once locked, the train can only be locked by other trains after the locked object passes.

[0023] As a further optimized solution of the present disclosure, the determination of the turnout locking order for trains with the same priority includes:

[0024] If the priorities of the trains are the same, the locking order is determined by calculating the minimum value of the total time T of the trains to pass through the turnout. The formula is as follows:

[0025] Ti = ∑(t 1i + t 2i + t 3i );

[0026] ;

[0027] Among them, t 1i is the time for the train to run to the turnout; t 2i is the time for the turnout to rotate and lock; t 3i is the time for the train to pass through the turnout area.

[0029] A priority sorting module, which is used to determine the leading vehicle of the virtual formation train among the leading vehicles of multiple train formations and sort the priorities of the trains in the current train formation;

[0030] A plan issuing module, which is used to issue a train operation plan to the leading vehicle of each train formation;

[0031] A path planning module, which is used to plan a train operation path for each train formation, predict the time for each train to pass through each turnout, and send path information to the leading vehicle of each train formation;

[0032] A primary locking module, which is used to apply for primary locking and attached time to the turnout, and send the information of the trains to pass through and the priority information of each train to the turnout;

[0033] A secondary locking module, which is used to control the leading vehicle of each train formation to apply for secondary locking to the turnout. After the secondary locking is successful for the train, the train passes through within the specified time;

[0034] A time calculation module, which is used to calculate the passing time of the train formation through the turnout and complete the secondary locking of each train according to the train priority;

[0035] A turnout passing module, which is used to enable the virtual formation train to pass through the turnout.

[0036] An electronic device includes a processor, a communication interface, a memory, and a communication bus. Among them, the processor, the communication interface, and the memory complete mutual communication through the communication bus;

[0037] The memory is used to store computer programs;

[0038] The processor is used to execute the programs stored in the memory to implement the turnout control method for virtual formation trains.

[0039] A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, a method for controlling turnout of a virtual formation train is implemented.

[0040] The beneficial effects of the present disclosure are as follows:

[0041] The present disclosure solves the turnout control problem of the formation change of a virtual formation train in the turnout area, and ensures the safety and efficiency of the train during operation. Description of the Drawings

[0042] Figure 1 is a flowchart of the method in the embodiment of the present disclosure;

[0043] Figure 2 is a block diagram of the system structure in the embodiment of the present disclosure;

[0044] Figure 3 is a block diagram of the device structure in the embodiment of the present disclosure. Detailed Embodiment

[0045] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following detailed embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0046] As Figure 1 shown, a method for controlling turnout of a virtual formation train includes the following steps:

[0047] Determine the head vehicle of the virtual formation train among the leading vehicles of multiple train formations, and sort the priorities of the trains in the current train formation (adjacent trains in the same running direction are automatically grouped into one formation);

[0048] Issue a train operation plan to the leading vehicle of each train formation (the plan indicates which trains are in one formation, the departure time and the destination);

[0049] Plan the train operation path for each train formation, predict the time for each train to pass through each turnout, and send the path information to the leading vehicle of each train formation;

[0050] Apply for first-level locking and the attached time to the turnout, and send the information of the trains to pass through and the priority information of each train to the turnout (which train formations can pass through, and the train priority white list is locked);

[0051] Control the leading vehicle of each train formation to apply for second-level locking to the turnout. After the second-level locking of the train is successful, the train passes through within the specified time;

[0052] Calculate the passing time of the train formation passing through the turnout, and complete the second-level locking of each train according to the train priority.

[0053] Let the virtual formation train pass through the turnout.

[0054] Trains with the same departure time can be grouped into a virtual formation train to be formed. The train priority determination method includes:

[0055] Highest priority: leading car;

[0056] High priority: The destinations of the next two stops are the same as those of the leading car;

[0057] Second priority: The destination of the next stop is the same as that of the leading car, and the destination of the second stop is different from that of the leading car;

[0058] Low priority: The destination of the next stop is different from that of the leading car.

[0059] The attached time calculation method includes:

[0060] Based on the train departure time, considering a series of times such as the train running to the turnout, the turnout rotating and locking, and the train passing through, and taking the time period when the train completely exits the turnout area (or station) as the standard. For example, the attached time can be calculated according to the departure of the last train to leaving the station, while considering a certain margin.

[0061] The turnout locking method includes:

[0062] The turnout locking is divided into first-level locking and second-level locking.

[0063] For the first-level locking, the leading car of the determined virtual formation train locks each original leading car in the virtual formation train. After the first-level locking, only the leading car of the virtual formation train in the white list can apply to the turnout for locking within the attached time.

[0064] For the second-level locking, each leading car applies to the turnout for locking. The locking method is the leading car of the train formation locking, which can include train formation locking and single-car locking. Once locked, the train can only be locked by other trains after the locked object passes. The granularity of the second-level locking can reach one train. It is not that the entire train formation needs to pass before it can be locked by other trains, but after the locked object such as a single car or multiple cars passes, the turnout can be locked by other trains.

[0065] The method for determining the turnout locking order of trains with the same priority includes:

[0066] Trains with higher priority pass first. In the case of the same priority, the locking order is determined by calculating the minimum value of the total time T of the trains waiting to pass through the turnout. This method can be applied locally or globally. The formula is as follows:

[0067] Ti = ∑(t 1i + t 2i + t 3i ) ;

[0068] ;

[0069] wherein, t 1i is the time when the train runs to the turnout; t 2i is the turnout rotation locking time (0 when the same as the train running direction; a fixed value when different from the train running direction); t 3i is the time when the train passes through the turnout area.

[0070] As Figure 2 shown, an embodiment of the present disclosure provides a turnout control system for a virtual formation train, including:

[0071] A priority sorting module, configured to determine the head vehicle of the virtual formation train among the leading vehicles of multiple train formations, and sort the priorities of the trains in the current train formation;
