Description

Technical Field

[0001] This invention relates to the field of train control technology, and in particular to a method, apparatus, device, medium, and program product for sending train operation permits. Background Technology

[0002] The Radio Block Center (RBC) is the core equipment of the train control system. It obtains route and block section status information from the interlocking equipment, calculates train operation permits based on track topology location information, and sends these permits wirelessly to the onboard equipment to ensure safe train operation.

[0003] The Track Controller (RBC) receives location information from onboard equipment and calculates its position on the track topology map. If there are not enough transponder pairs installed on the tracks or throat areas within a station for positioning, or if a train stops at a station and changes direction multiple times, or if a transponder pair is lost during train operation, the RBC cannot guarantee the accuracy of the calculated track topology position. Based on this inaccurate track topology position, the train travel permission sent by the RBC poses a certain safety risk. Summary of the Invention

[0004] This invention provides a method, apparatus, device, medium, and program product for sending train operation permits to ensure the accuracy of line topology location, thereby improving the safety of train operation.

[0005] In a first aspect, embodiments of the present invention provide a method for sending a vehicle permit, comprising:

[0006] Based on the real-time location report information of the target train, determine the track topology location and the operating track to which the track topology location belongs; the real-time location report information includes the real-time transponder group identifier;

[0007] Based on the line topology location, real-time transponder group identifier, area information of the reliable area in the running track, and the identifier of the transponder group in the reliable area, the authenticity of the line topology location is verified, and the verification result of the line topology location is obtained.

[0008] If the verification result is true, then a train operation permit will be sent to the target train.

[0009] Secondly, embodiments of the present invention also provide a vehicle permit sending device, comprising:

[0010] The determination module is used to determine the track topology location and the operating track to which the track topology location belongs based on the real-time location report information of the target train; the real-time location report information includes the real-time transponder group identifier;

[0011] The verification module is used to verify whether the line topology location is true based on the line topology location, the real-time transponder group identifier, the area information of the trusted area in the running track, and the identifier of the transponder group in the trusted area, and to obtain the verification result of the line topology location.

[0012] The sending module is used to send a train operation permit to the target train if the verification result is true.

[0013] Thirdly, embodiments of the present invention also provide an electronic device, comprising:

[0014] At least one processor; and

[0015] A memory that is communicatively connected to at least one processor; wherein

[0016] The memory stores instructions that can be executed by at least one processor, which enables the at least one processor to perform the method for sending driving permits provided in any embodiment of the present invention.

[0017] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the method for sending a vehicle permit according to any embodiment of the present invention.

[0018] Fifthly, embodiments of the present invention also provide a computer program product, characterized in that the computer program product includes a computer program, which, when executed by a processor, implements the method for sending a vehicle permit according to any embodiment of the present invention.

[0019] This invention determines the track topology location and the operating track to which the target train belongs based on the real-time location report information. The real-time location report information includes the real-time transponder group identifier. The accuracy of the track topology location is verified based on the track topology location, the real-time transponder group identifier, the area information of a reliable area within the operating track, and the identifier of the transponder group within the reliable area. A verification result is obtained. If the verification result is accurate, a train operation permit is sent to the target train. This invention can determine whether the target train is actually located on the track by using the area information of a reliable area within the track and the identifier of the transponder group within the reliable area. If the target track topology location is accurately located on the track, a train operation permit is sent to it, avoiding incorrect train operation permits due to inaccurate track topology location and improving train operation safety.

[0032] Example 1

[0033] Figure 1A This is a flowchart of a method for sending train operation permits according to Embodiment 1 of the present invention. This embodiment can be applied to the situation of sending train operation permits to trains. The method can be executed by a train operation permit sending device, which can be implemented in hardware and / or software and specifically configured in electronic equipment, such as a radio block center device.

[0034] See Figure 1A The method for sending driving permits, as shown, includes:

[0035] S101. Based on the real-time location report information of the target train, determine the track topology location and the operating track to which the track topology location belongs; the real-time location report information includes the real-time transponder group identifier.

[0036] In this embodiment, the target train can be a train that is in motion. The real-time location report information can be the location report information sent by the train in real time; the track topology location can be the position of the train in the running track topology; the running track is the track where the track topology location is located, that is, the track on which the train is currently traveling.

[0037] In this embodiment, the target train is equipped with onboard equipment. Each time the target train passes a transponder group, the onboard equipment can report the target train's relative position based on that transponder group to a device deployed with the train permission transmission method of this embodiment. The real-time position report information may include, but is not limited to, real-time transponder group identifiers, position offsets, and train direction of travel. Specifically, the real-time transponder group identifier can be the identifier of the transponder group that the train has passed in real time; the transponder group identifier can be used to uniquely identify the transponder group; the transponder group can consist of at least one transponder; and the position offset can be the position offset of the train based on the transponder group it has passed in real time.

[0038] Specifically, the position of the real-time transponder group in the train line topology can be determined based on the real-time transponder group identifier; the line topology position of the train can be determined based on the position offset and the position of the real-time transponder group in the train line topology, and the train track to which the line topology position belongs can be further determined.

[0039] Optional, Figure 1B It is a train route topology map. For example... Figure 1B As shown, the track includes track I, track II, track III, and track IV. Track I is equipped with signal K1, signal V1, and transponder group BG13; there are turnouts 12 and 5 between track I and track II; track II is equipped with signal 101a, signal A, signal K2, signal V2, signal C, and transponder groups BG2, BG4, BG6, BG11, and BG12; there are turnouts 2 and 4 between track II and track III. Turnout 6, turnout 8, turnout 1 and turnout 3; Track III is equipped with signal 101b, signal B, signal K3, signal V3, signal D, transponder group BG1, transponder group BG3, transponder group BG5, transponder group BG9 and transponder group BG10; there are turnout 10 and turnout 7 between Track III and Track IV; Track IV is equipped with signal K4, signal V4, transponder group BG7 and transponder group BG8.

[0040] For example, when a target train is traveling on track II and passes transponder group BG1, it sends a real-time position report relative to transponder group BG1. This real-time position report includes the real-time transponder group identifier that the target train has passed, i.e., the identifier of transponder group BG1, and the position offset based on transponder group BG1. Figure 1B The relative position shown is 452m, and the train's direction of travel is to the right. Based on the real-time position report information, the target train's position on the track topology map can be determined, specifically 452m to the right of transponder group BG1.

[0041] For example, Figure 1CThis is a schematic diagram illustrating the distortion of line topology location. For example... Figure 1C As shown, if the target train travels towards signal V4 after passing transponder group BG8, passing turnout 7 and turnout 3 in sequence, and then returns to the station at signal C, stopping and changing direction (i.e., changing the direction of travel), in this situation... Figure 1C If transponder groups BG10, BG12, and BG14 malfunction, the target train will consistently send position reports based on transponder group BG8, even if it enters any track. It will be unable to send position reports based on the transponder group on the new track it enters. During this switching operation, the target train's offset relative to transponder group BG8 undergoes a process of increasing, remaining constant, and decreasing. In this process, if the position offset in the position report is small enough—less than the distance between transponder group BG8 and any turnout—then the target train's track topology position determined by the position report will still be near BG8 on track IV, while the actual track topology position of the target train will be on track I, track II, or track III. This results in low accuracy and unreliability of the target train's track topology position. In one alternative implementation, if signal V4 is in an open state, it will send a train travel permit to the target train; if the target train is actually in track I and signal V1 does not meet the open condition, it will cause a train travel hazard.

[0042] In one optional embodiment, the real-time location report information may include the train line topology location; the line topology location can be obtained from the real-time location report information of the target train, and the operating track to which the line topology location belongs can be determined.

[0043] Optionally, based on the real-time location report information of the target train, the topological location of the line and the running track to which the topological location belongs are determined, including: determining the auxiliary location based on the real-time location report information of the target train; if there is only one auxiliary location, then the auxiliary location is determined as the topological location of the line; and determining the running track to which the topological location belongs.

[0044] In this optional embodiment, the number of auxiliary positions determined based on the real-time position report information of the target train can be one or more; if the number of auxiliary positions is one, the auxiliary position is determined as the line topology position; the running track to which the line topology position belongs is determined; if the number of auxiliary positions is multiple, it can be determined that each auxiliary position is unreliable, the real-time position report information is ignored, and the new position report information is awaited in the future.

[0045] For example Figure 1BTaking the train route topology diagram shown as an example, when the target train travels forward and passes transponder group BG5, due to the uncertainty of the state of switch 2 (e.g., switch 2 may be in a normal, reversed, or unknown state), multiple different position results will be calculated. That is, the calculated result may be a position between switch 2 and switch 8, or it may be a position between switch 2 and switch 4. In this case, the route topology position of the target train cannot be uniquely determined, and it can be determined that the route topology position calculation of the target train has failed.

[0046] It is understandable that by adopting the above technical solution, the number of auxiliary positions can be used to determine the auxiliary position as the line topology position when there is only one auxiliary position, thus ensuring that a unique line topology position is obtained and ensuring the accuracy of the line topology position.

[0047] S102. Based on the line topology location, real-time transponder group identifier, area information of the reliable area in the running track, and the identifier of the transponder group in the reliable area, verify whether the line topology location is real and obtain the verification result of the line topology location.

[0048] In this embodiment, the trusted region can be a track area with two transponder groups as endpoints on the running track. The region information of the trusted region can be used to characterize its location and length, etc. The identifier of the transponder group within the trusted region can be the identifier of the transponder group located within the trusted region.

[0049] Specifically, a certain algorithm is used to verify whether the line topology location is real based on the line topology location, the real-time transponder group identifier, the regional information of the reliable area in the running track, and the identifier of the transponder group in the reliable area, and to obtain the verification result of the line topology location.

[0050] Optionally, at least two transponder pairs are installed on the track of the target train; each transponder pair includes two transponder groups; the transponder groups of each transponder pair are different; one transponder group from each transponder pair is installed on one side of the track; the other transponder group from each transponder pair is installed on the other side of the track; for each transponder pair, the distance between the two transponder groups in the transponder pair is determined; the transponder pair with a smaller distance is determined as a reliable transponder pair; the track area with the two transponder groups in the reliable transponder pair as endpoints is determined as a reliable area.

[0051] The train track can be any track that the target train can travel on; the number of train tracks can be at least one. It is understood that by adopting the above technical solution, transponder pairs that are close together can be identified as reliable transponder pairs, and the track area with the two transponder groups in the reliable transponder pair as endpoints can be identified as a reliable region, thus creating a reliable region.

[0052] In an optional embodiment, at least one transponder group may be provided in the trusted region in addition to the transponder group at the endpoint of the trusted region. For example... Figure 1D As shown, a transponder group can be set at the midpoint of the trusted region to increase the frequency of the target train sending position report information, thereby reducing the position error of the target train.

[0053] Optional, Figure 1D It is a train route topology map that includes reliable regions. For example... Figure 1D As shown, Figure 1D exist Figure 1B Based on the train track topology diagram shown, a reliable region is established on track I, along with redundant transponder groups BG15, BG16, BG17, BG18, and BG19. Redundant transponder groups BG15 and BG18 can form a transponder pair; BG16 and BG17 can form a transponder pair; and BG13 and BG14 can form a transponder pair. The reliable region is the track area with redundant transponder groups BG13 and BG14 as endpoints. Redundant transponder group BG19 is also included in the reliable region to reduce the positional error of the target train.

[0054] By setting up redundant transponder groups BG15, BG16, BG17, and BG18, a target train entering from either side of track I will send a position report information because it passes through the redundant transponder groups. Even if any transponder group on the entering side is lost, the position report information can still be sent in a timely manner through the other transponder group, thus improving the reliability of the train's position.

[0055] S103. If the verification result is true, then a train operation permit is sent to the target train.

[0056] Specifically, if the verification result is true, a driving permit can be calculated for the target train and sent to the target train so that the target train can continue to travel; otherwise, the real-time location report information is ignored and the train waits for a new location report in the future.

[0057] This invention determines the track topology location and the operating track to which the target train belongs based on the real-time location report information. The real-time location report information includes the real-time transponder group identifier. The accuracy of the track topology location is verified based on the track topology location, the real-time transponder group identifier, the area information of a reliable area within the operating track, and the identifier of the transponder group within the reliable area. A verification result is obtained. If the verification result is accurate, a train operation permit is sent to the target train. This invention can determine whether the target train is actually located on the track by using the area information of a reliable area within the track and the identifier of the transponder group within the reliable area. If the target track topology location is accurately located on the track, a train operation permit is sent to it, avoiding incorrect train operation permits due to inaccurate track topology location and improving train operation safety.

[0058] Example 2

[0059] Figure 2 This is a flowchart of a method for sending a train permit according to Embodiment 2 of the present invention. Based on the technical solution of the above embodiments, the embodiment of the present invention optimizes and improves the line topology location verification operation.

[0060] Furthermore, the process of "verifying the authenticity of the line topology location based on the line topology location, real-time transponder group identifier, area information of the trusted area in the running track, and the identifier of the transponder group within the trusted area, and obtaining the verification result of the line topology location" is refined into "detecting whether the line topology location is within the trusted area based on the line topology location and the area information of the trusted area, and obtaining the detection result; querying the real-time transponder group identifier among the identifiers of the transponder group within the trusted area, and obtaining the query result; determining the verification result of the line topology location based on the detection result and the query result," in order to improve the determination operation of alarm containers and unprocessed lingering containers.

[0061] It should be noted that for any parts not described in detail in the embodiments of the present invention, please refer to the description in the foregoing embodiments.

[0062] See Figure 2 The method for sending driving permits shown includes:

[0063] S201. Based on the real-time location report information of the target train, determine the track topology location and the operating track to which the track topology location belongs; the real-time location report information includes the real-time transponder group identifier.

[0064] S202. Based on the location of the line topology and the regional information of the trusted region, detect whether the location of the line topology is within the trusted region and obtain the detection result.

[0065] In this embodiment, the detection result may include, but is not limited to, being within a trusted region and being outside a trusted region; a detection result of being within a trusted region indicates that the line topology location is located within the trusted region; a detection result of being outside a trusted region indicates that the line topology location is located outside the trusted region. Specifically, based on the regional information of the trusted region, the range of the line topology location within the trusted region is determined; whether the line topology location of the target train is located within the range of the line map location within the trusted region is detected to obtain the detection result.

[0066] S203. Within the trusted area, query the real-time transponder group identifier from the transponder group identifiers to obtain the query results.

[0067] In this embodiment, the query result may include, but is not limited to, existence and null value. Specifically, the real-time transponder group identifier is queried from the identifiers of transponder groups within the trusted area; if the real-time transponder group identifier is found in the identifiers of transponder groups within the trusted area, the detection result is determined to be existence; if the real-time transponder group identifier is not found in the identifiers of transponder groups within the trusted area, the query result is determined to be null value.

[0068] S204. Based on the detection results and query results, determine the verification results of the line topology location.

[0069] Specifically, a certain algorithm is used to determine the verification result of the line topology location based on the detection results and query results.

[0070] Optionally, based on the detection results and query results, the verification result of the line topology location is determined, including: if the detection result is in the trusted region and the query result is that it exists, then the verification result of the line topology location is determined to be true.

[0071] It is understandable that by adopting the above technical solution, when the detection result is in the trusted area and the query result is that the line topology location verification result is true, the accuracy of the line topology location verification can be improved.

[0072] Optionally, if the detection result is outside the trusted area, or the query result is not found, the historical transponder group identifier and the real-time transponder group identifier in the historical location report information of the target train are compared to obtain the comparison result; the reception time of the historical location report information is adjacent to the reception time of the real-time location report information, and the reception time of the historical location report information is before the reception time of the real-time location report information; if the comparison result is inconsistent, the verification result of the line topology location is determined to be true.

[0073] Understandably, by adopting the above technical solution, it is possible to determine whether the transponder group on which the target train's position report information is based has changed by comparing the historical transponder group identifier and the real-time transponder group identifier, thereby determining whether the target train has passed the new transponder group; if the target train has passed the new transponder group, then the verification result of the line topology position is confirmed to be true, thus improving the accuracy of verifying the line topology position.

[0074] S205. If the verification result is true, then a train operation permit is sent to the target train.

[0075] This invention, through its embodiments, detects whether the line topology location is within a trusted region based on the line topology location and the region information of the trusted region, obtaining a detection result; queries the real-time transponder group identifiers within the identifiers of transponder groups in the trusted region, obtaining a query result; and determines the verification result of the line topology location based on the detection result and the query result. This allows for the detection of whether the train's location is within the trusted region's location range, and whether the transponder group the train passes through is a transponder group within the trusted region. Furthermore, by combining the detection results at the location dimension and the query information at the transponder group dimension, the verification result of the train's location is determined, improving the accuracy of train location verification.

[0080] The verification module 302 is used to verify whether the line topology location is real based on the line topology location, the real-time transponder group identifier, the area information of the reliable area in the running track and the identifier of the transponder group in the reliable area, and to obtain the verification result of the line topology location.

A sending module sends a train operation permit to the target train if the verification result is authentic, confirming whether the target train is truly located in the track.
