Description

Technical Field

[0001] This disclosure belongs to the field of rail transit technology, and in particular relates to a method, system, electronic device and storage medium for tracking the position of trains at a station. Background Technology

[0002] Train numbers are crucial information for the Centralized Train Control (CTC) system, enabling dispatching, train tracking, automatic track data collection, automatic route planning, wireless route announcements, and wireless dispatching commands. Currently, the CTC system tracks train numbers logically based on real-time track circuit status data.

[0003] However, during train control, train operations between different stations can cause new trains to suddenly appear in the train tracking systems of different stations. If these new trains are not controlled, it can easily lead to station congestion. Therefore, how to track trains between different stations has become an urgent technical problem to be solved. Summary of the Invention

[0004] To address the aforementioned issues, this disclosure provides a method, system, electronic device, and storage medium for tracking train positions at stations. This solution utilizes the location information of ad hoc train groups to track train operations between different stations, ensuring efficient train operation.

[0005] To address the aforementioned technical problems, the first aspect of this invention provides a method for tracking train positions at a station, the method comprising:

[0006] Obtain the location information of each train from the train control system of the self-organizing network train group;

[0007] For the (N-1)th received location information, determine the block section rail A corresponding to the train to be tracked; for the Nth received location information, determine the block section rail B corresponding to the train to be tracked; N is a positive integer and N is greater than 1;

[0008] If the block section rail A is located at the current station and is connected to the adjacent station, and the block section rail B is located at the adjacent station and is connected to the block section rail A; when the actual running direction of the train to be tracked is consistent with the running direction of the block section rail A moving to the block section rail B, the train to be tracked shall be tracked by train number.

[0009] According to a preferred embodiment of the present invention, the tracking method further includes:

[0010] For any of the trains to be tracked, determine the train number of the train to be tracked, and determine whether there is a train with the same train number at the current station based on the track circuit status information;

[0011] If there is a train with the same train number at the current station, and the train belongs to an ad hoc train group, then the train is matched with the train to be tracked.

[0012] If there is a train with the same train number at the current station, and the train does not belong to the self-organizing network train group, then the train attribute of the train will be modified to belong to the self-organizing network train group.

[0013] If there is no train with the same train number at the current station, then the train to be tracked is a newly added train at the current station.

[0014] According to a preferred embodiment of the present invention, the step of tracking the train number to be tracked includes:

[0015] Determine whether the train to be tracked is located on the block section track A, and whether there is a train with the same train number as the train to be tracked on the block section track B;

[0016] When the train to be tracked is located on track A of the block section, and there is no train with the same train number on track B of the block section, the location information received by the train to be tracked times out.

[0017] Alternatively, when the train to be tracked is located on block section track A, and there is a train with the same train number on block section track B, and the train to be tracked has already been tracked by the train tracking system of the adjacent station, the train to be tracked will be removed from the train tracking system of the current station.

[0018] According to a preferred embodiment of the present invention, the tracking method further includes:

[0019] When the actual running direction of the train to be tracked is inconsistent with the running direction of the train moving from block section A to block section B; determine whether the train to be tracked is located on block section A;

[0020] When the train to be tracked is located on track A of the block section, the train to be tracked has been cancelled and removed from the train tracking system of the current station.

[0021] According to a preferred embodiment of the present invention, the tracking method further includes:

[0022] For any train to be tracked, determine the train number of the train to be tracked; determine whether there is a train with the same train number in the Nth received position information based on the track circuit status information;

[0023] When the Nth received location information does not contain a train with the same train number;

[0024] If the (N-1)th received location information contains a train with the same train number, and the train is not located on the block section of the current station, then the train to be tracked is removed from the train tracking system of the current station; or, if the (N-1)th received location information contains a train with the same train number, and the train is located on both the block section of the current station and the block section of an adjacent station, then the train to be tracked is removed from the train tracking system of the current station.

[0025] or,

[0026] When the Nth received location information contains a train with the same train number;

[0027] If the location information of the train to be tracked changes compared with the location information received in the Nth time and the (N-1)th time, then the train to be tracked is tracked according to the preset train number window movement rule;

[0028] If the location information of the train to be tracked has not changed compared with the location information received in the Nth time, then no processing is required on the location information of the train to be tracked.

[0029] If no train with the same train number is found in the (N-1)th received location information, the train to be tracked is added to the train tracking system of the current station.

[0030] According to a preferred embodiment of the present invention, the tracking method further includes:

[0031] The main train secondary window equipment and the auxiliary train secondary window equipment set for the block section equipment corresponding to each block section track are sorted and numbered, wherein the numbers of the main train secondary window equipment and the auxiliary train secondary window equipment are consecutive, and the number of the main train secondary window equipment is set as the starting point of the sequence.

[0032] Additional train window equipment is numbered sequentially according to its distance from the block section equipment on the station map, from closest to farthest.

[0033] When tracking train numbers, trains enter the train number window device sequentially according to the time the train enters the block section track and the train number window number.

[0034] According to a preferred embodiment of the present invention, the tracking method further includes:

[0035] When a train is being cleared from any block section, determine whether there is a train in the block section ahead.

[0036] When there is no train in the block section track ahead, the trains in the main train secondary window equipment and the auxiliary train window equipment in the block section equipment corresponding to the block section track are updated in order of number to the main train secondary window equipment and the auxiliary train window equipment in the block section equipment corresponding to the block section track ahead.

[0037] Alternatively, when there is a train in the preceding block section, if the train in the preceding block section belongs to the self-organizing network train group, then the trains in the main train secondary window equipment and the auxiliary train secondary window equipment in the block section equipment corresponding to the block section are updated in order of number to the vacant auxiliary train secondary window equipment without trains in the block section equipment corresponding to the preceding block section.

[0038] Alternatively, when there is a train in the preceding block section, if the train in the preceding block section does not belong to the ad hoc network train group, then wait for the train in the preceding block section to be removed, and after the train in the preceding block section is removed, update the trains in the main train secondary window equipment and the auxiliary train secondary window equipment in the block section equipment corresponding to the block section to the main train secondary window equipment and the auxiliary train secondary window equipment in the block section equipment corresponding to the preceding block section in order of their numbers.

[0039] To address the aforementioned technical problems, a second aspect of the present invention provides a station train location tracking system, the system comprising:

[0040] The location information acquisition module is used to acquire the location information of each train provided by the train control system of the self-organizing network train group;

[0041] The train position determination module is used to determine the block section track A corresponding to the train to be tracked for the (N-1)th received position information; and to determine the block section track B corresponding to the train to be tracked for the Nth received position information; N is a positive integer and N is greater than 1;

[0042] The train tracking module is used to track the train when the actual running direction of the train to be tracked is consistent with the running direction of the train moving from block track A to block track B, provided that block track A is located at the current station and is connected to the adjacent station, and block track B is located at the adjacent station and is connected to block track A.

[0043] Compared with existing technologies, this disclosure has the following advantages: This disclosure utilizes the location information of each train provided by the train control system of an ad hoc train group. When two consecutive location information results in the corresponding block section tracks of the train to be tracked being located at different stations but connected, the disclosure determines whether to track the train based on whether the actual running direction of the train crosses two stations, thus optimizing the train tracking scheme between different stations. This scheme uses the location information of the ad hoc train group to track train operations between different stations, ensuring train operation efficiency.

[0044] Other features and advantages of this disclosure will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the disclosure.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0055] The same reference numerals in the accompanying drawings denote the same or similar elements, components, or parts, and therefore, repeated descriptions of the same or similar elements, components, or parts may be omitted below. It should also be understood that although terms such as first, second, third, etc., indicating numbers may be used herein to describe various devices, elements, components, or parts, these devices, elements, components, or parts should not be limited by these terms. That is, these terms are only used to distinguish one from another. For example, a first device may also be referred to as a second device, without departing from the essential technical solution of the invention. Furthermore, the terms "and / or" and "and / or" refer to all combinations including any one or more of the listed items.

[0056] Please see Figure 1 , Figure 1 This is a schematic diagram of one of the station train location tracking methods provided by the present invention, as shown below. Figure 1 As shown, the method includes:

[0057] S11. Obtain the location information of each train provided by the train control system of the self-organizing network train group.

[0058] In this embodiment, the self-organizing network train group is an innovative operation mode in the field of rail transit technology. It enables direct communication between trains based on self-organizing network technology, thereby allowing multiple trains to form a group for collaborative operation.

[0059] In this embodiment, the train number is typically determined in the station's CTC system by real-time acquisition of track circuit status information. Although the real-time track circuit status information can accurately determine the train's position, the CTC system only supports tracking of train numbers for single trains entering a semi-automatic block section. Under the ad hoc train group operation mode, ad hoc train groups are allowed to enter the same semi-automatic block section. In this scenario, when multiple trains from an ad hoc group enter the same semi-automatic block section, the CTC system cannot logically track the train numbers.

[0060] In this embodiment, the location information of the self-organizing network train group is combined with the real-time track circuit status information to perform two-dimensional tracing of the train tail, thereby realizing the tracking of stations in the block section across stations under the self-organizing network train group operation mode.

[0061] In this embodiment, since the train location information provided by the ad hoc train group is not a real-time global notification, there may be a situation where the group status information times out, that is, the location information times out, and the current real-time location of the train cannot be accurately determined. In this case, the current location of the train and the train operation status in the block section are accurately determined by combining the track circuit status information in the CTC system.

[0062] S12. For the (N-1)th received position information, determine the block section rail A corresponding to the train to be tracked; for the Nth received position information, determine the block section rail B corresponding to the train to be tracked; N is a positive integer and N is greater than 1.

[0063] In this embodiment, the train is located on block section track B based on the train location information provided by the ad hoc train group. Then, the train is located on block section track A based on the previously provided train location information. If block section track A and block section track B are the same, the train's position has not changed. If block section track A and block section track B have changed, then from the perspective of the ad hoc train group, the train's position has changed, and train tracking is required.

[0064] S13. If block section rail A is located at the current station and is connected to the adjacent station, and block section rail B is located at the adjacent station and is connected to block section rail A; when the actual running direction of the train to be tracked is consistent with the running direction of the block section rail A moving to the block section rail B, the train to be tracked shall be tracked by train number.

[0065] In this embodiment, when block section track A is located at the current station and is connected to the adjacent station, and block section track B is located at the adjacent station and is connected to block section track A, then block section track A and block section track B change and are located on the block section tracks of the current station and the adjacent station, respectively.

[0066] In this embodiment, it is further determined whether the actual running direction of the train to be tracked is consistent with the running direction of the train moving from block section A to block section B. If the actual running direction of the train to be tracked is inconsistent with the running direction of the train moving from block section A to block section B, it indicates that there is a significant error in the group status information of the train to be tracked, and the train to be tracked has been deregistered from the ad hoc network train group. At this time, the train to be tracked is removed from the train tracking system of the current station, and there is no need to track the train to be tracked.

[0067] In this embodiment, if the actual running direction of the train to be tracked is consistent with the running direction of the train moving from block section A to block section B, then the train to be tracked needs to be tracked. The position of the train to be tracked is determined by the track circuit status information at this time. When the train to be tracked is located on block section A and there is no train with the same train number on block section B, the position information received by the train to be tracked times out. When the train to be tracked is located on block section A and there is a train with the same train number on block section B, the train to be tracked has been tracked by the train tracking system of the adjacent station, and the train to be tracked is removed from the train tracking system of the current station.

[0068] In this embodiment, the Nth received location information in this scheme is the group status information of the self-organizing network train group received in the above embodiment, while the (N-1)th received location information is the group status information of the self-organizing network train group received in the previous embodiment.

[0069] This disclosure utilizes the location information of each train provided by the train control system of an ad hoc train group. When two consecutive location data points determine that the block section corresponding to the train to be tracked is located at different stations but connected, the system determines whether to track the train based on whether the actual running direction of the train crosses two stations, thus optimizing the train tracking scheme between different stations. This scheme uses the location information of the ad hoc train group to track train operations between different stations, ensuring train operation efficiency.

[0070] Please see Figure 2 , Figure 2 This is a second schematic diagram of a station train location tracking method provided by the present invention, as shown below. Figure 2 As shown, the method includes:

[0071] S21. For any train to be tracked, determine the train number of the train to be tracked, and determine whether there is a train with the same train number at the current station based on the track circuit status information.

[0072] In this embodiment, when the group status information of each train in the ad hoc network train group is received at any time, the train to be tracked is determined according to the group status information. Specifically, the train can be identified by its train number, which can be obtained from the group status information.

[0073] In this embodiment, the presence of a train with the specified train number in the current station is determined by the track circuit status information. In other words, the presence of the train to be tracked in the current station is determined collaboratively by the track circuit status information and the group status information of the ad hoc train group.

[0074] S22. If there is a train with the same train number at the current station, and the train belongs to the self-organizing network train group, then the train is matched with the train to be tracked.

[0075] In this embodiment, if there is a train with the same train number in the current station, and the train is determined to belong to the self-organizing network train group by the track circuit status information, it can be determined that the train matches the train to be tracked, the train matches the location information, and the self-organizing network train exists in the location information.

[0076] S23. If there is a train with the same train number at the current station, and the train does not belong to the self-organizing network train group, then change the train attribute to belong to the self-organizing network train group.

[0077] In this embodiment, if the track circuit status information determines that a train with the same train number exists in the current station, but the train does not yet belong to the self-organizing network train group in the current station's train attributes, then the train attributes need to be modified to self-organizing network group train.

[0078] S24. If there is no train with the same train number at the current station, the train to be tracked is a newly added train at the current station.

[0079] In this embodiment, if the track circuit status information determines that there is no train with the same train number in the current station, it means that the group status information transmitted by the ad hoc network train group indicates that the train to be tracked is about to enter the current station. At this time, the train to be tracked is added to the current station in advance to prepare for tracking the train to be tracked.

[0080] Please see Figure 3 , Figure 4 , Figure 3 , Figure 4 The third and fourth schematic diagrams of the station train location tracking method provided by this invention are as follows: Figure 3 , Figure 4 As shown, the method includes:

[0081] S31. For any train to be tracked, determine the train number of the train to be tracked; determine whether there is a train with the same train number in the Nth received position information based on the track circuit status information.

[0082] In this embodiment, when the group status information of each train in the ad hoc train group is received at any time, the train to be tracked is determined according to the group status information. Specifically, the train can be identified by its train number, which can be obtained from the group status information.

[0083] In this embodiment, the presence of a train with the specified train number in the current station is determined by the track circuit status information. Specifically, the track circuit status information and the group status information of the ad hoc train group are used to collaboratively determine whether the train to be tracked is located in the current station when the location information is received for the Nth time.

[0084] S32a. When there is no train with the same train number in the Nth received location information.

[0085] In this embodiment, if the track circuit status information determines that the train to be tracked is not located at the current station when the location information is received for the Nth time, it means that the train to be tracked has not yet entered the current station, or that the location information received for the Nth time is delayed information, and the train to be tracked has already left the current station.

[0086] S33. If the location information received in the (N-1)th time contains a train with the same train number, and the train is not located on the block section of the current station, then the train to be tracked will be removed from the train tracking system of the current station; or, if the location information received in the (N-1)th time contains a train with the same train number, and the train is located on the block section of the current station and the block section of the adjacent station, then the train to be tracked will be removed from the train tracking system of the current station.

[0087] In this embodiment, if it is determined that the train to be tracked is not located at the current station when the location information is received for the Nth time, the status of the train to be tracked is determined by the previous location information, that is, the status of the train to be tracked is determined by whether the location information received for the N-1th time exists.

[0088] In this embodiment, if the location information received in the (N-1)th time contains a train with the same train number, and the train is not located on the block section track of the current station, it indicates that the location information received in the Nth time may be erroneous, such as delay information or data error information. In this case, the train to be tracked will be removed from the train tracking system of the current station.

[0089] In this embodiment, if the location information received in the (N-1)th time contains a train with the same train number, and the train is located on the block section track of the current station and the block section track of the adjacent station, it means that the train will leave the current station. At this time, the train to be tracked will be removed from the train tracking system of the current station.

[0090] In this embodiment, if the location information received in the (N-1)th time contains a train with the same train number and the train is located on the block section track of the current station, it means that the train to be tracked is still in the current station. However, when the location information is received in the Nth time, the train to be tracked is not in the current station, and no processing is performed on the train to be tracked at this time.

[0091] Alternatively, S32b, when the Nth received location information contains a train with the same train number.

[0092] In this embodiment, when the track circuit status information determines that the train to be tracked is located at the current station when the location information is received for the Nth time, it is necessary to track the train to be tracked in real time. At this time, the location information of the ad hoc network train group and the track circuit status information collected in real time are combined to track the train within the station.

[0093] S34. If the position information of the train to be tracked changes compared with the position information received in the Nth time, the train to be tracked shall be tracked according to the preset train number window movement rule.

[0094] S35. If the position information of the train to be tracked has not changed compared with the position information received in the Nth time, then the position information of the train to be tracked will not be processed.

[0095] In this embodiment, if the location information of the train to be tracked changes compared to the location information received in the (N-1)th time, it indicates that the train to be tracked has moved or is about to move. In this case, the train to be tracked is tracked according to the preset train number window movement rules. Otherwise, no processing of the location information of the train to be tracked is required.

[0096] S36. When there is no train with the same train number in the location information received in the (N-1)th time, add the train to be tracked in the train tracking system of the current station.

[0097] In this embodiment, when there is no train with the same train number in the location information received in the (N-1)th time, the track circuit status information determines that the train to be tracked is not in the current station. At this time, it indicates that the train to be tracked is about to enter the current station, and the train to be tracked is added to the train tracking system of the current station.

[0098] Please see Figure 5 , Figure 5 This is a schematic diagram of the fifth step in the process of a station train location tracking method provided by the present invention, as shown below. Figure 5 As shown, the method includes:

[0099] S41. The main train secondary window equipment and the auxiliary train secondary window equipment set for the block section equipment corresponding to each block section are sorted and numbered. The numbers of the main train secondary window equipment and the auxiliary train secondary window equipment are consecutive, and the number of the main train secondary window equipment is set as the starting point of the sequence.

[0100] In this embodiment, the semi-automatic block zoning equipment allows for one main train secondary window and N auxiliary train secondary windows. A single section track equipment may only have a main train secondary window; if an auxiliary train secondary window is to be installed on a single section track equipment, a main train secondary window must already be installed.

[0101] S42. Additional train window equipment, numbered sequentially according to the distance from the block section equipment on the station map, from closest to farthest.

[0102] In this embodiment, the main train windows and auxiliary train windows of the semi-automatic block track equipment are sorted and numbered. The main train window is numbered 0, and the auxiliary train windows are sorted in order of distance from the track equipment in the station map from near to far, and are numbered as number 1, number 2, ..., number N.

[0103] In this embodiment, when the train is logically tracked, it enters the train window device in sequence number 0, number 1, ..., number N according to the time of entering the section track.

[0104] S43. When tracking train numbers, enter the train number window device in sequence according to the time the train enters the block section track and the train number window number.

[0105] In this embodiment, for self-organizing network trains that simultaneously enter the same section of track equipment through the self-organizing network train group location information, they are sorted from near to far according to the relative position of the distance blocking signal in the self-organizing network train group location information, and enter the train window equipment of sequence number 0, sequence number 1, ..., sequence number N in sequence.

[0106] like Figure 6 As shown, in this embodiment, the method for clearing a train within an arbitrary block section includes:

[0107] S51. When a train is being cleared from any block section, determine whether there is a train in the block section ahead.

[0108] In this embodiment, during railway operation, "train clearance" means that a train has cleared a certain interlocking section, which can be occupied by other trains or construction work.

[0109] In this embodiment, since multiple trains are allowed to travel in the same block section, it is necessary to determine whether there are still trains in the block section preceding the one requiring train clearance, in order to achieve train operation control. In this embodiment, the preceding block section refers to the first block section preceding the one requiring train clearance.

[0110] S52. When there is no train in the block section ahead, the trains in the main train secondary window equipment and the auxiliary train secondary window equipment in the block section equipment corresponding to the block section ahead shall be updated in order of number to the main train secondary window equipment and the auxiliary train secondary window equipment in the block section equipment corresponding to the block section ahead.

[0111] In this embodiment, when there are no trains in the track of the block section ahead, and it is necessary to push all the trains on the associated train window equipment to the train window of the equipment ahead, the original order of the trains on the equipment should be maintained, and they should be moved in sequence to the empty train window ahead.

[0112] S53. Alternatively, if there is a train in the preceding block section, and the train in the preceding block section belongs to an ad hoc train group, then the trains in the main train window equipment and auxiliary train window equipment in the block section equipment corresponding to the block section will be updated sequentially in order of their numbers to the vacant auxiliary train window equipment of the block section equipment corresponding to the preceding block section.

[0113] In this embodiment, when there are trains in the block section ahead, and the trains are self-organizing network group trains, and it is necessary to push all the trains on the associated train window device to the train window of the device ahead, the original order of the trains on the device should be maintained, and they should be moved in sequence to the empty train window ahead.

[0114] S54. Alternatively, if there is a train in the preceding block section, and the train in the preceding block section does not belong to the ad hoc network train group, then wait for the train in the preceding block section to move out. After the train in the preceding block section moves out, update the trains in the main train secondary window equipment and the auxiliary train secondary window equipment in the block section equipment corresponding to the block section to the main train secondary window equipment and the auxiliary train secondary window equipment in the corresponding block section equipment in the order of their numbers.

[0115] In this embodiment, when there is a train in the block section ahead, but the train is not a self-organizing network group train, the order of the trains on the clearing equipment should be maintained, and they should not be moved to the empty train window ahead. When the train in the main train window moves out and the block section is cleared and reoccupied, when all the trains on the associated train window equipment are pushed to the train window of the equipment ahead, the original order of the trains on the equipment should be maintained, and they should be moved to the empty train window ahead in sequence.

[0116] Please see Figure 7 , Figure 7 This invention provides a station train location tracking system, with reference to... Figure 7 The system includes: a location information acquisition module 11, a train location determination module 12, and a train number tracking module 13.
