Abstract
Description
Technical Field
[0001] This invention relates to the field of rail transit technology, and in particular to a method and apparatus for determining compound turningouts in an electronic rail transit map. Background Technology
[0002] With the increasing travel demands, people are traveling to multiple destinations. This requires trains to connect these destinations, necessitating multiple routes on the tracks. Double-ended turnouts can simultaneously provide multiple routes and offer advantages such as saving floor space and shortening the throat, effectively meeting spatial constraints and operational needs. This has led to their increasing application in urban rail transit. Since double-ended turnouts are used for the intersection of four tracks, involving numerous track branches and junctions, current electronic track maps for trains cannot accurately determine all the junctions of these turnouts. This makes it difficult to accurately locate trains at double-ended turnout locations on the electronic track map, hindering the implementation of safety protection functions at these locations. Therefore, it is necessary to consider more accurate determination of double-ended turnouts on the electronic track map to achieve accurate train positioning and thus provide safety protection.
[0003] In existing technologies, the determination of compound intersection turnouts in electronic track maps mainly adopts a simplified two-point model. Figure 1 A simplified two-point model diagram is schematically shown; see [link / reference]. Figure 1 As shown, specifically: First, obtain the actual travel paths AB, CD, AD, and CB of the train; second, determine the center intersection point of the intersection area of the straight paths AB and CD; finally, extend the center intersection point horizontally to the left by a first distance within the intersection area to determine the first branch point 1, and extend it horizontally to the right by a second distance to determine the second branch point 2, with the sum of the first and second distances being less than 1 meter.
[0004] However, the method of determining the branch point in the track electronic map by the center intersection point of the intersection area of two straight paths has a problem: since the branch point in the track electronic map is within the intersection area, while the actual branch point of the double-spinning turnout is outside the intersection area, the branch point in the track electronic map is different from the actual branch point of the double-spinning turnout, which will cause the train to be positioned inaccurately on the double-spinning turnout. Summary of the Invention
[0005] The purpose of this application is to provide a method and apparatus for determining double-headed turnouts in a track electronic map, so as to solve the problem that the position of the turnout in the track electronic map is different from the actual position of the double-headed turnout, which will cause the train to be inaccurately positioned on the double-headed turnout.

[0016] Based on the described travel path, the four junctions are configured as two sets of double-acting turnouts;
[0017] The track connectivity mode of the map model is configured according to the double-acting turnout, and the track connectivity mode is used to determine the currently available connected tracks of the double-acting turnout in the electronic track map.
[0018] In some modified embodiments of the first aspect of this application, the configured map model is connected to the four tracks in the track electronic map according to the connectivity relationship between the four tracks, including:

[0020] The driving path is used to match the corresponding branch points in the map model for each track;
[0021] The map model is updated to the electronic track map based on the correspondence between the tracks and the branch points, so that the map model is connected to the four tracks.
[0022] In some modified embodiments of the first aspect of this application, after connecting the configured map model to the four tracks in the track electronic map according to the connectivity relationship between the four tracks, the method further includes:
[0023] Acquire the status of each set of double-acting turnouts, including the turnout positioning status and the turnout reversal status;
[0024] The track connectivity mode of the map model is determined based on the status of each set of double-acting turnouts;
[0025] Based on the track connectivity mode, the currently available connected tracks in the track electronic map are realized for the compound switching turnout.
[0026] A second aspect of this application provides a device for determining compound turnouts in a track electronic map, comprising:
[0027] The determination module is used to determine the four tracks that connect the double-headed turnouts in the electronic track map;
[0028] A configuration module is used to configure a map model of a compound turnout with four branch points, the positions of which correspond to the positions of the straight tip of the four rails connecting the compound turnout.
[0029] The connection module is used to connect the configured map model to the four tracks in the electronic track map according to the connectivity between the four tracks, so as to locate the position of the train passing through the double-intersection turnout in real time on the electronic track map.
[0030] In some modified embodiments of the second aspect of this application, the configuration module is specifically used to determine the map positions of the four branch points in the electronic track map based on the geographical locations of the straight tip of the branch point connecting the four tracks in the compound crossover turnout; configure the connecting tracks between the four branch points according to the train's travel path on the four tracks; and generate the map model of the compound crossover turnout based on the map positions of the four branch points and the connecting tracks.
[0031] In some modified embodiments of the second aspect of this application, the configuration module is specifically used to configure the four branch points as two sets of double-acting turnouts according to the travel path; and to configure the track connectivity mode of the map model according to the double-acting turnouts, wherein the track connectivity mode is used to determine the currently available connected tracks of the compound branching turnouts in the track electronic map.
[0032] A third aspect of this application provides an electronic device, the electronic device comprising: at least one processor; and at least one memory and bus connected to the processor; wherein the processor and memory communicate with each other through the bus; the processor is configured to call program instructions in the memory to execute the method for determining a double-heading turnout in a track electronic map as described in the first aspect or any optional embodiment of the first aspect.

[0034] Compared to existing technologies, the method for determining compound turnouts in the electronic track map provided in the first aspect of this application configures a map model of a compound turnout with four branch points based on the position of the straight tip of the turnout connecting the four tracks. This ensures that the four branch points in the map model correspond perfectly to the positions of the straight tip of the actual compound turnout. Then, based on the connectivity between the four tracks, the configured map model is connected to the four tracks in the electronic track map. This allows the actual compound turnout to be displayed in the electronic track map, ensuring that the four branch points in the electronic track map correspond one-to-one with the four branch points of the actual compound turnout, and that the positions of the four branch points in the electronic track map are identical to the positions of the four branch points of the actual compound turnout. This enables real-time location of trains passing through the compound turnout on the electronic track map, making the train positioning on the compound turnout more accurate. Compared to existing technologies that determine two branch points in the electronic track map by identifying the center intersection point of two straight paths, thus obtaining a simplified two-point model of the double-ended turnout in the electronic track map, this invention does not require determining the branch points in the electronic track map, which differs from the actual number of branch points in the double-ended turnout, by using the center intersection point of the straight path intersection area. The number of branch points in the electronic track map needs to be the same as the actual number of branch points in the double-ended turnout. The positions of the four branch points in the electronic track map are determined by the positions of the four straight-pointed rail tips of the double-ended turnout connected by four tracks, making the branch point positions in the electronic track map exactly the same as the actual branch point positions in the double-ended turnout, thereby making the train positioning on the double-ended turnout more accurate.

[0045] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.
[0046] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.
[0047] For determining the position of a compound turningout in a track electronic map, existing technology determines the two turning points in the track electronic map by identifying the center intersection point of the intersection area of two straight paths. These two turning points are then defined as two single-moving turning points, resulting in a two-point simplified model of the compound turningout in the track electronic map. However, because the turning points in the track electronic map determined by the existing technology are within the intersection area, while the actual turning point of the compound turningout is outside the intersection area as determined by the turning point of the straight switch rail, the positions of the turning points in the track electronic map and the actual turning points differ, leading to inaccurate train positioning on the compound turningout. Therefore, this invention, considering the difference between the positions of the two turning points in the track electronic map of the two-point simplified model and the actual turning points of the compound turningout, replaces the two-point simplified model with a model where the turning point positions in the track electronic map are identical to those in the actual compound turningout. Therefore, this invention selects to design a model in which the location of the branch point in the electronic track map completely corresponds to the location of the branch point in the actual double-junction turnout. Since the location of the straight tip of the actual double-junction turnout is the location of the branch point, and there are four straight tip of the actual double-junction turnout, meaning there are four branch points, four branch points must also be set in the electronic track map accordingly. The locations of the four branch points in the electronic track map must completely correspond to the locations of the straight tip of the actual double-junction turnout. This ensures that the location of the branch point in the electronic track map completely corresponds to the location of the branch point in the actual double-junction turnout. Based on the location of the branch point in the actual double-junction turnout, the location of the branch point in the electronic track map that is exactly the same as the location of the branch point in the actual double-junction turnout can be determined, making the positioning of the train on the double-junction turnout more accurate. The specific implementation method involves identifying the four tracks connecting the double-headed turnout in the electronic track map, configuring a map model of the double-headed turnout with four branch points, the positions of the four branch points corresponding to the positions of the straight tip rails of the double-headed turnout connecting the four tracks, and connecting the configured map model with the four tracks in the electronic track map according to the connectivity between the four tracks, so as to locate the position of the train passing through the double-headed turnout in real time on the electronic track map.
[0048] The methods described in the embodiments of the present invention will be explained in detail below.
[0049] Figure 2 The flowchart of the method for determining compound turningouts in the electronic track map according to an embodiment of the present invention is illustrated schematically. Figure 1 See Figure 2 As shown, the method may include:
[0050] S201. Determine the four tracks connecting the double-headed turnouts in the electronic track map.
[0051] In practice, double-headed turnouts are connected by four tracks. Therefore, the four tracks connecting the double-headed turnouts also need to be identified in the electronic track map to ensure that the tracks in the electronic track map correspond to the actual double-headed turnouts. The four tracks corresponding to the double-headed turnouts in the electronic track map are determined based on the four tracks connecting the actual double-headed turnouts.
[0052] The four tracks connecting the double-headed turnouts in the electronic track map were determined by obtaining the civil engineering data of the line.
[0053] S202, Configure a map model for a compound crossover turnout with 4 branch points.
[0054] The positions of the four branch points correspond to the positions of the straight tip of the turnout connecting the four tracks in the compound intersection turnout.
[0055] Specifically, the position of the straight tip of the four-track connecting double-headed turnout can be determined by obtaining the civil engineering data and turnout structure diagram. Then, a map model of the double-headed turnout with four branch points can be configured based on the position of the straight tip of the four-track connecting double-headed turnout.
[0056] Since an actual double-ended turnout includes four straight switch rails, the map model is configured with the same number of switch points as the four straight switch rails of the actual double-ended turnout. In other words, the map model of the double-ended turnout with four switch points is configured so that the four switch points in the map model correspond one-to-one with the positions of the four straight switch rails of the actual double-ended turnout.
[0057] The map model can include four paths, corresponding to path AB, path CB, path AD, and path CD respectively. See [link / reference] Figure 3 As shown, Figure 3 This diagram schematically illustrates the method for determining compound turnouts in a track electronic map. The track map includes four tracks, corresponding to tracks ab, c, d, and cd, and four branch points, corresponding to branch point 1, 2, 3, and 4. It also includes four paths, corresponding to paths AB, CB, AD, and CD. Track ab is the track corresponding to path AB; track c is the track from point C of path CB to branch point 4; track d is the track from point 1 to point D of path AD; and track cd is the track from point 2 to point 3. A map model illustrating this correspondence can be found [link to map model]. Figure 4 As shown, Figure 4The diagram schematically illustrates a map model of the method for determining compound turnouts in a track electronic map. The map model may include: turnout point 1 being the position of the straight tip of the turnout connecting tracks ab and d; turnout point 2 being the position of the straight tip of the turnout connecting tracks c and cd; turnout point 3 being the position of the straight tip of the turnout connecting tracks d and cd; and turnout point 4 being the position of the straight tip of the turnout connecting tracks ab and c.
[0058] S203. Based on the connectivity between the four tracks, connect the configured map model to the four tracks in the electronic track map so as to locate the position of the train passing through the double-switching turnout in real time on the electronic track map.
[0059] Specifically, based on the connectivity between the four tracks, the map model configured in step S202 is connected to the four tracks determined in step S201 in the electronic track map, so as to locate the position of the train passing through the double-switching turnout in real time on the electronic track map.
[0060] A double-heading turnout has four tracks, some connected and some disconnected. Trains can only travel smoothly on the connected tracks. The connectivity between the different tracks is essential for train operation. By establishing these connectivity relationships, a configured map model can be linked to the four tracks in a track electronic map. The resulting track electronic map, formed by the connected map model and the four tracks, serves as the positioning map for train movement. The track electronic map allows for real-time location tracking of trains passing through the double-heading turnout.
[0061] The method for determining compound turnouts in a track electronic map provided in this invention configures a map model of a compound turnout with four branch points based on the position of the straight tip of the turnout connecting the four tracks. This ensures that the four branch points in the map model perfectly correspond to the positions of the straight tip of the actual compound turnout. Then, based on the connectivity between the four tracks, the configured map model is connected to the four tracks in the track electronic map. This allows the actual compound turnout to be displayed in the track electronic map, ensuring that the four branch points in the track electronic map correspond one-to-one with the four branch points of the actual compound turnout, and that the positions of the four branch points in the track electronic map are identical to the positions of the four branch points of the actual compound turnout. This enables real-time location of trains passing through the compound turnout on the track electronic map, making train positioning on the compound turnout more accurate. Compared to existing technologies that determine two branch points in the electronic track map by identifying the center intersection point of two straight paths, thus obtaining a simplified two-point model of the double-ended turnout in the electronic track map, this invention does not require determining the branch points in the electronic track map, which differs from the actual number of branch points in the double-ended turnout, by using the center intersection point of the straight path intersection area. The number of branch points in the electronic track map needs to be the same as the actual number of branch points in the double-ended turnout. The positions of the four branch points in the electronic track map are determined by the positions of the four straight-pointed rail tips of the double-ended turnout connected by four tracks, making the branch point positions in the electronic track map exactly the same as the actual branch point positions in the double-ended turnout, thereby making the train positioning on the double-ended turnout more accurate.
[0062] Furthermore, as Figure 2 As a refinement and extension of the method shown, this embodiment of the invention also provides a method for determining compound turningouts in a track electronic map.
[0063] Figure 5 The flowchart of the method for determining compound turningouts in the electronic track map according to an embodiment of the present invention is illustrated schematically. Figure 2 See Figure 5 As shown, the method for determining compound turningouts in the electronic track map provided in this embodiment of the invention may include:
[0064] S501. Determine the four tracks in the electronic track map that connect the double-headed turnouts.
[0065] For example, the four tracks connecting the double-headed turnout in the electronic track map are identified as track ab, track c, track d, and track cd.
[0066] S502. Determine the map positions of the four branch points in the electronic track map based on the geographical location of the straight switch tip connecting the four tracks in the double-ended turnout.
[0067] In a real double-switching turnout, the tip of the straight switch connecting the four tracks is the actual junction point of the double-switching turnout. In other words, the geographical location of the tip of the straight switch connecting the four tracks in a real double-switching turnout is the geographical location of the junction point. Based on the geographical location of the tip of the straight switch connecting the four tracks in a double-switching turnout, the map positions of the four junction points in the map model can be determined on the electronic track map.
[0068] Following the example of step S501, the geographical locations of the straight switch points connecting the four tracks in a compound turnout are geographical location 1, geographical location 2, geographical location 3, and geographical location 4, respectively. Therefore, based on geographical locations 1, 2, 3, and 4, the map positions of the four switch points in the map model on the electronic track map can be determined as map position 1, map position 2, map position 3, and map position 4, respectively. If the four switch points in the map model are switch point 1, switch point 2, switch point 3, and switch point 4, then, based on geographical location 1, the map position 1 of switch point 1 in the map model is determined as map position 1 on the electronic track map; based on geographical location 2, the map position 2 of switch point 2 in the map model is determined as map position 2 on the electronic track map; based on geographical location 3, the map position 3 of switch point 3 in the map model is determined as map position 3 on the electronic track map; and based on geographical location 4, the map position 4 of switch point 4 in the map model is determined as map position 4 on the electronic track map.
[0069] S503. Configure the four branch points as two sets of double-acting turnouts according to the travel route.
[0070] In practice, a double-switching turnout typically uses one switch machine to pull the turnouts at two different points. Depending on the train's route, two fixed turnouts at different points are also pulled by one switch machine. In other words, the turnouts at two fixed points pulled by one switch machine are configured as a set of double-moving turnouts. Therefore, four turnouts can be configured as two sets of double-moving turnouts according to the train's route.
[0071] Following the example of step S502, the train's travel path is path AB, path CB, path AD, and path CD. Based on the train's travel path, it is determined that the turnouts at branch points 1 and 2 are pulled by one switch machine, meaning that the turnouts at branch points 1 and 2 are a set of double-acting turnouts. Alternatively, it can be determined that the turnouts at branch points 3 and 4 are pulled by another switch machine, meaning that the turnouts at branch points 3 and 4 are another set of double-acting turnouts. In this way, the four branch points can be configured as two sets of double-acting turnouts.
[0072] S504. Configure the track connection mode of the map model according to the double-acting turnout.
[0073] Among them, the track connectivity mode is used to determine the currently available connected tracks in the track electronic map for compound turnouts.
[0074] Specifically, the track connectivity mode of the map model can be configured based on the two sets of double-acting turnouts configured in step S503. The track connectivity mode can determine the currently available connected tracks in the electronic track map for the double-acting turnouts.
[0075] When configuring the track connectivity mode of the map model, each set of double-acting turnouts has two states: one is the turnout positioning state and the other is the turnout reversing state. The track connectivity mode of the map model is a combination of different states of the two sets of double-acting turnouts. By using the track connectivity mode, i.e., the combination of different states of the two sets of double-acting turnouts, the currently available connected tracks in the track electronic map can be determined.
[0076] The different combinations of the two sets of double-acting turnouts can be: a combination of one set of double-acting turnouts in the fixed position and the other set in the fixed position; a combination of one set of double-acting turnouts in the fixed position and the other set in the reverse position; a combination of one set of double-acting turnouts in the reverse position and the other set in the fixed position; and a combination of one set of double-acting turnouts in the reverse position and the other set in the reverse position.
[0077] Following the example of step S503, if one set of double-acting turnouts is called turnout 1-2 and the other set is called turnout 3-4, the track connectivity mode of the map model for turnouts 1-2 and 3-4 is determined to be turnout 1-2 in a fixed position and turnout 3-4 in a fixed position. Based on the track connectivity mode of the map model for turnouts 1-2 and 3-4 in a fixed position, the currently available connected track for the compound crossover turnout in the track electronic map can be determined to be track ab. The track connectivity mode of the map model for turnouts 1-2 and 3-4 is determined to be turnout 1-2 in a fixed position and turnout 3-4 in a reversed position. Based on the track connectivity mode of the map model for turnouts 1-2 in a fixed position and turnout 3-4 in a reversed position, the currently available connected track for the compound crossover turnout in the track electronic map can be determined. The track connection mode of the map model for turnouts 1-2 and 3-4 is determined to be that turnout 1-2 is in reverse position and turnout 3-4 is in position. Based on the track connection mode of the map model for turnouts 1-2 in reverse position and turnout 3-4 in position, the currently available connected tracks for the compound crossover turnout in the electronic track map are determined to be the track connecting track ab and track d.
[0078] S505, a map model for generating compound turnouts based on the map locations of the four branch points and the connecting tracks.
[0079] Specifically, based on the map positions of the four branch points in the track electronic map determined in step S502, and according to the currently available connected tracks of the compound crossover turnout in the track electronic map determined in step S504, a map model of the compound crossover turnout is generated.
[0080] The map model of the double-ended turnout, generated based on the map locations of the four branch points and the connecting tracks, corresponds completely to the actual double-ended turnout. The map model includes the corresponding tracks of all tracks and the corresponding branch points of all straight-point turnouts in the actual double-ended turnout. In other words, the generated map model is a perfect match for the physical structure of the actual double-ended turnout.
[0081] Following the example of step S504, a map model for a compound turnout is generated based on the map position 1 of branch point 1 in the electronic track map, the map position 2 of branch point 2 in the electronic track map, the map position 3 of branch point 3 in the electronic track map, the map position 4 of branch point 4 in the electronic track map, and the connected tracks ab, c and the track connected to ab, ab and d, and c, cd and d.
[0082] As an optional embodiment of the present invention, the map position of the branch point 1 on the main track ab can be determined based on the distance of the straight tip 1 of the actual compound crossover turnout relative to the starting point of the main track ab. The distances 1-4 between the straight tip 4 and the straight tip 1 of the actual compound crossover turnout, the distances 1-3 between the straight tip 3 and the straight tip 1 of the actual compound crossover turnout, and the distances 2-4 between the straight tip 2 and the straight tip 4 of the actual compound crossover turnout are measured according to the track centerline. The distances between any two branch points in the map model are the same as the distances between any two straight tips of the actual compound crossover turnout. Therefore, from left to right, the starting point of the main track ab is point 1. The map position of point 4 on the main track ab can be determined by distances 1-4. The ending point of the main track ab is point 4. The map position of point 3 on track d can be determined by distances 1-3. The starting point of track d is point 1, and the ending point is point 3. The map position of point 2 on track c can be determined by distances 2-4. The starting point of track c is point 2, and the ending point is point 4. The starting point of track cd is point 2, and the ending point is point 3. When determining the map positions of the four points, the coordinate systems of the four tracks can be independent. That is, the starting point of track d can use the coordinates of point 1 on track ab, or it can use 0.
[0083] S506. Determine the train's travel path on the four tracks.
[0084] Following the example of step S505, since the train can travel on the four tracks in many ways, such as: AB on track ab, CB on the connected track c and track ab, AD on the connected track ab and track d, and CD on the connected track c, track cd and track d, but not AC and BD, it is necessary to determine the specific travel path of the train on the four tracks.
[0085] S507. Match the corresponding branch points in the map model for each track according to the travel path.
[0086] Specifically, based on the train's travel path on the four tracks determined in step S506, the corresponding branch points in the map model are matched for each track.
[0087] Following the example of step S506, if the determined travel path is path AB, the corresponding branch points in the map model for track ab are branch point 1 and branch point 4, the corresponding branch points in the map model for track c are branch point 2 and branch point 4, the corresponding branch points in the map model for track cd are branch point 2 and branch point 3, and the corresponding branch points in the map model for track d are branch point 1 and branch point 3.
[0088] S508. Update the map model to the electronic track map based on the correspondence between the track and the branch point, so that the map model is connected to the four tracks.
[0089] Specifically, based on the branch points corresponding to each track in the map model matched in step S507, that is, based on the correspondence between the track and the branch points, the map model is updated to the track electronic map so that the map model is connected to the four tracks.
[0090] The map model needs to be updated to the electronic track map based on the correspondence between the tracks and the turnouts. This allows the map model to be connected to the four tracks, forming an electronic track map for the train's location at the double turnout. This electronic track map can serve as a positioning map for the train's movement. Based on the electronic track map, the real-time location of the train traveling at the double turnout can be determined, thereby determining the train's accurate position at the double turnout.
[0091] Following the example of step S507, based on the branch points 1 and 4 corresponding to track ab, the branch points 2 and 4 corresponding to track c, the branch points 2 and 3 corresponding to track cd, and the branch points 1 and 3 corresponding to track d, the map model can be updated to the electronic track map, so that the map model is connected to the four tracks to form an electronic track map. The formed electronic track map can be used as a positioning map for train movement.
[0092] S509. Obtain the status of each set of double-acting turnouts.
[0093] The states include turnout positioning state and turnout reversed state.
[0094] In step S508, the map model is updated to the electronic track map based on the correspondence between the track and the turnout. After the map model is connected to the four tracks, the electronic track map of the already configured double-turnout can be applied. During the train's operation, it is necessary to obtain the turnout positioning status and turnout reversal status of each set of double-acting turnouts.
[0095] Following the example of step S508, if one set of double-acting turnouts is called turnout 1-2 and the other set of double-acting turnouts is called turnout 3-4, turnout 1-2 can be in the fixed position and turnout 3-4 can be in the fixed position, turnout 1-2 can be in the fixed position and turnout 3-4 can be in the reverse position, turnout 1-2 can be in the reverse position and turnout 3-4 can be in the fixed position, and turnout 1-2 can be in the reverse position and turnout 3-4 can be in the reverse position.
[0096] S510. Determine the track connectivity mode of the map model based on the status of each set of double-acting turnouts.
[0097] Specifically, the track connectivity mode of the map model is determined based on the status of each set of double-acting turnouts obtained in step S509.
[0098] The track connectivity mode of the map model is a combination of the states of two sets of switches. There are four track connectivity modes in the map model: a combination of one set of switches being in the fixed state and the other set of switches being in the fixed state; a combination of one set of switches being in the fixed state and the other set of switches being in the reversed state; a combination of one set of switches being in the reversed state and the other set of switches being in the fixed state; and a combination of one set of switches being in the reversed state and the other set of switches being in the reversed state.
[0099] Following the example from step S509, based on the obtained information that turnouts 1-2 and 3-4 are in a fixed position, the track connectivity mode of the map model can be determined to be a combination of the fixed positions of turnouts 1-2 and 3-4. Based on the obtained information that turnouts 1-2 are in a fixed position and turnouts 3-4 are in a reversed position, the track connectivity mode of the map model can be determined to be a combination of the fixed positions of turnouts 1-2 and 3-4. Based on the obtained information that turnouts 1-2 are in a reversed position and turnouts 3-4 are in a fixed position, the track connectivity mode of the map model can be determined to be a combination of the reversed positions of turnouts 1-2 and 3-4. Based on the obtained information that turnouts 1-2 are in a reversed position and turnouts 3-4 are in a reversed position, the track connectivity mode of the map model can be determined to be a combination of the reversed positions of turnouts 1-2 and 3-4.
[0100] S511. Based on the track connectivity mode, realize the currently available connected tracks for the double-headed turnout in the track electronic map.
[0101] Specifically, based on the track connectivity mode determined in step S510, the currently available connected tracks for the compound turnouts in the track electronic map are realized.
[0102] Following the example from step S510, based on the combination of the positioning states of turnouts 1-2 and 3-4 in the track connectivity mode of the map model, the currently available connected track for the compound crossover turnout in the track electronic map is track ab, allowing the train to travel smoothly on track ab. Based on the combination of the positioning states of turnouts 1-2 and 3-4 in the reverse position of the track connectivity mode of the map model, the currently available connected track for the compound crossover turnout in the track electronic map is the track connecting track c and track ab, allowing the train to travel smoothly on the track connecting track c and track ab. Based on the combination of the reverse position of turnouts 1-2 and 3-4 in the track connectivity mode of the map model, the currently available connected track for the compound crossover turnout in the track electronic map is the track connecting track ab and track d, allowing the train to travel smoothly on the track connecting track ab and track d. Based on the track connectivity mode of the map model, which is a combination of the reversed states of turnouts 1-2 and 3-4, the currently available connected tracks in the electronic track map for the double-switching turnout can be track c, track cd, and track d. Trains can then travel smoothly on the track c, track cd, and track d connected in the electronic track map.
[0103] Based on the determined track connectivity patterns, when implementing the double-spinning turnout in the track electronic map, since there are four track connectivity patterns in the map model, four corresponding currently available connecting tracks in the track electronic map can also be determined. Based on the combination of the positioning states of turnouts 1-2 and 3-4 in the track connectivity pattern, the currently available connecting track for the double-spinning turnout in the track electronic map is track ab, and the path corresponding to track ab is path AB. Based on the combination of the positioning states of turnouts 1-2 and 3-4 in the track connectivity pattern, the currently available connecting track for the double-spinning turnout in the track electronic map is the track connecting track c and track ab, and the path corresponding to the track connecting track c and track ab is path CB. Based on the track connectivity pattern 1-2... The combination of the reversed position of turnouts and the positioning position of turnouts 3-4 allows the currently available connected tracks in the electronic track map for the compound crossover turnout to be the track connecting tracks ab and d, with the path corresponding to the track connecting tracks ab and d being path AD. Based on the track connectivity mode of the combination of the reversed position of turnouts 1-2 and 3-4, the currently available connected tracks in the electronic track map for the compound crossover turnout can be the track connecting tracks c, cd, and d, with the path corresponding to the track connecting tracks c, cd, and d being path CD. The specific track connectivity modes of the map model that need to be determined are shown in Table 1. Table 1 shows the track connectivity modes of the map model.

[0106] Figure 6 The diagram schematically illustrates the currently available connected track authorization map for methods of determining double-heading turnouts in the electronic track map. See [link to relevant documentation]. Figure 6 As shown, a travel path can be authorized based on a connectivity mode. In the case of a combination of track connectivity modes with 1-2 turnout positioning and 3-4 turnout positioning, the track electronic map only authorizes paths such as... Figure 6 In (a), the connecting track ab is path AB. No other connecting tracks are authorized, so the train will travel on path AB, passing through junctions 1 and 4. When the track connection mode is a combination of the 1-2 turnout positioning state and the 3-4 turnout reversing state, the electronic track map only authorizes tracks such as... Figure 6 (b) The track connected to track c and track ab is path CB. No other connecting tracks are authorized, so the train will travel on path CB. Trains traveling on path CB will pass through junctions 2 and 4. In the case of a combination of track connection modes of reversed state of turnout 1-2 and fixed state of turnout 3-4, the electronic track map only authorizes tracks such as... Figure 6 (c) The track connected to tracks ab and d is path AD. No other connecting tracks are authorized, so trains will travel on path AD, passing through junctions 1 and 3. In the case of a combination of track connection modes with the reversed states of turnouts 1-2 and 3-4, the electronic track map only authorizes tracks such as... Figure 6 In (d), the track connected to track c, track cd and track d is path CD. No other connecting tracks are authorized. In this way, the train will travel on path CD. The train traveling on path CD will pass through branch point 2 and branch point 3.
