Description

Technical Field

[0001] This invention relates to the field of rail transit coupling and uncoupling, and in particular to a data processing method, equipment and medium for coupled areas of rail transit. Background Technology

[0002] In recent years, with the development of urban rail transit, more and more cities across the country have built driverless rail transit projects. However, after the subways are put into operation, the different passenger flows during morning and evening peak hours and off-peak hours mean that multi-unit trains are not required to be in operation at all times. In order to reduce energy consumption, improve operational efficiency, and increase operational flexibility, operating units have proposed the need for train coupling. By configuring coupling and decoupling areas in the system data, and then calculating the coupling area using system data tools, trains can be coupled when they are located in the coupling area.

[0003] After searching, many existing papers and patents involve coupling and uncoupling schemes, such as the paper "Research on Online Coupling and Uncoupling Technology of Metro Trains in Unmanned Driving Mode" and Chinese Patent No. CN112078596A, which discloses a train coupling method, uncoupling method and device.

[0004] However, the above scheme does not provide a detailed description of the definition and implementation method of the specific linked area in the system data. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art and provide a data processing method, device and medium for the connected areas of rail transit.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0012] Step S101: Set the track for each coupling and uncoupling area;

[0013] Step S102: Configure service stops and trains for parking in each coupling and uncoupling area;

[0014] Step S103: Configure each coupling / decoupling area with trains that are allowed to perform coupling / decoupling operations in the current coupling / decoupling area.

[0019] Step S204: Calculate the linkage and unlinking region to which the currently linked region belongs;

[0020] Step S205: Calculate the track where the linked area is located.

[0021] As a preferred technical solution, the automatic range calculation method in step S201 is as follows: if the direction of the service stop is Up, extend the service stop upstream by one train length plus one stop error distance, and extend the service stop downstream by one stop error distance; if the direction of the service stop is Down, extend the service stop downstream by one train length plus one stop error distance, and extend the service stop upstream by one stop error distance.

[0022] As a preferred technical solution, in the kilometer markers automatically calculated in step S202, the kilometer marker with the smaller value is the beginning of the linked area; and the kilometer marker with the larger value is the end of the linked area.

[0023] As a preferred technical solution, in step S203, the direction of the coupling area is the direction in which the train is coupled, which is consistent with the direction of the service stopping point.

[0024] As a preferred technical solution, in step S2, the train currently associated with the coupled area serves as the basis for automatically calculating the train after the coupling is completed, and the length of the train after the coupling is completed is twice the length of the coupled train.

[0025] As a preferred technical solution, the automatic creation of the protection authorization zone in step S3 specifically includes the following steps:

[0026] Step S301: Extend the protection distance from the boundary of the linked area as the authorized protection area for the linked area;

[0033] According to a third aspect of the present invention, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method described thereon.

[0034] Compared with the prior art, the present invention has the following advantages:

[0035] 1) This invention fills the gap in the current system data regarding the definition of the coupled areas of driverless trains;

[0036] 2) The system data configuration of this invention is simple. Users only need to configure a few parameters in the system data. The data table of the linked area is automatically calculated and generated by the data tool, which reduces manual input.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0041] The purpose of this invention is to enable a system data tool to automatically calculate the coupling area and related data based on a small amount of manually defined and configured line parameter information during the system data implementation phase of a project. This calculated system data can then be used by downstream subsystems and software, allowing the system to achieve fully automated train coupling. The automatic calculation by the system data tool significantly reduces the workload of manually calculating the coupling area, thereby reducing labor costs for the project and improving the efficiency and accuracy of system data production.

[0042] This invention mainly includes:

[0043] 1. Based on the design documents, the data production personnel configure the Coupling_Uncoupling_Area in the system data.

[0044] 1.1 System Data Structure

[0049] TFC_ID_List: Defines the trains used for coupling and uncoupling in the coupling and uncoupling area.

[0050] 2. Based on the above-configured linked and unlinked zones, the system data tool automatically calculates the linked zone (Be_Coupled_Zone).

[0051] 2.1 System Data Structure

[0052] ID: Defines the serial number of the linked region;

[0053] Name: Defines the name of the linked region;

[0054] Direction: Defines the direction in which the coupled area is used for the trains to enter;

[0069] 4. The specific implementation method of this invention is as follows:

[0070] Step 1: The system data creators create a Coupling_Uncoupling_Area data table and define an ID and name for each Coupling_Uncoupling area;

[0071] Step 2: Set the track (Track_ID) for each coupling and uncoupling area, and ensure that the same coupling and uncoupling area cannot cross tracks during data production;

[0072] Step 3: For each coupling and uncoupling area, configure a service parking point (SSP_ID_List) as needed for parking. This parking point is used for the accurate parking of the train and subsequent coupling operations.

[0073] Step 4: Configure each coupling / decoupling area with trains (TFC_ID_List) that are allowed to perform coupling / decoupling operations in the current coupling / decoupling area;

[0074] Step 5: Based on the system data definitions from Steps 1 to 4, and considering the trains associated with the service stopping points, the system data tool automatically calculates the range of the coupled area, as follows:

[0075] If the service parking spot is facing Up:

[0076] Extend the distance upstream of the service stop by one train length plus one stopping error distance; extend the distance downstream of the service stop by one stopping error distance.

[0077] If the service parking spot is facing Down:

[0078] Extend the distance downstream of the service stop by one train length plus one stopping error distance; extend the distance upstream of the service stop by one stopping error distance.

[0079] Step 6: After completing the expansion in Step 5, calculate the starting kilometer marker and the ending kilometer marker of the linked area: the kilometer marker with the smaller value is the starting point (Kp_Begin) of the linked area; the kilometer marker with the larger value is the ending point (Kp_End) of the linked area.

[0080] Step 7: Calculate the direction of the coupled area, which refers to the coupled direction of the train, which is consistent with the direction of the service stopping point;

[0081] Step 8: Calculate the linkage and delinking area to which the current linkage area belongs based on the linkage and delinking area where the service parking point is located;

[0082] Step 9: Calculate the train length used in Step 5 when calculating the range of the coupled area, and calculate the train associated with the current coupled area;

[0083] Step 10: Calculate the track where the coupled area is located based on the track configuration of the coupled and uncoupled areas;

[0084] Step 11: Based on the trains associated with the coupled area calculated in Step 9, calculate the train after the coupling is completed. The length of this train is twice the length of the coupled train.

[0085] Step 12: Sort all the connected regions after calculation, and assign an ID and name to each connected region;

[0086] Step 13: Based on the direction of the linked area calculated in Step 7, extend the protection distance from the boundary of the linked area calculated in Step 5 in that direction to form the linked protection authorization zone. Create a protection authorization zone for each linked area;

[0087] Step 14: Define the direction of the linked protection authorization area, which is consistent with the direction of the linked area;

[0088] Step 15: Calculate the logical segment containing the endpoint of the linked protection authorization zone as the logical segment containing the end of the extended protection distance in Step 13. The offset is the distance between the end and the beginning of the logical segment;

[0089] Step 16: Add serial numbers and names to all created linked protection authorization zones in sequence;

[0090] Step 17: Associate the serial number of the created linked protection authorization zone with the linked zone.

[0091] The present invention will now be described in detail with reference to the accompanying drawings:

[0092] like Figure 1 As shown, users can first configure the Coupling_Uncoupling_Area according to the project implementation requirements. The area contains information such as serial number, name, track, service stopping point, and train types applicable to coupling.

[0093] Once the linked and unlinked zones are configured, use the system data tool to calculate the linked zone (Be_Coupled_Zone) data table and the linked protection authorized zone (Be_Coupled_MAOZ_Chains) data table respectively.

[0094] The linked area data table contains information such as serial number, name, direction, area start, area end, train to be linked, train after linking, associated linked protection authorization area, and associated linking and unlinking area.

[0095] The table of linked authorized protection zones contains information such as sequence number, name, direction, logical segment, and offset. The calculated sequence number of the linked authorized protection zone is associated with the linked protection zones, indicating which authorized protection zones protect that linked zone.
