[0003] The existing train operation control system's mechanism for sending track data is highly dependent on train control equipment and communication networks. It cannot achieve timely transmission of track data when encountering sections without network coverage. Furthermore, the engineering design, construction, and upgrading costs are high, and it also cannot meet the requirements for efficient storage and use of track data. Summary of the Invention

[0011] The location and route information acquisition module is used to acquire the location information of the target train in the group train within the station yard and the real-time updated route processing information; wherein, the route processing information includes the routes that have been processed.

[0012] The candidate topology route determination module is used to determine the station line data and at least one candidate topology route corresponding to the target train based on the location information, the route processing information, the open status of each signal and the status of each section. Different candidate topology routes correspond to the same currently processed route and different section lines.

[0013] The target topology route determination module is used to send the station line data to the target train, and determine a unique target topology route from the at least one candidate topology route based on the real-time updated route processing information and section locking conditions.

[0014] The line data sending module is used to send the current station line data and the section line data corresponding to the target topology line to the target train.

[0015] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0016] At least one processor; and

[0017] A memory communicatively connected to the at least one processor; wherein,

[0018] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the group train line data transmission method according to any embodiment of the present invention.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0036] Figure 1AThis is a flowchart illustrating a method for transmitting line data for a group of trains according to an embodiment of the present invention. This embodiment is applicable to transmitting line data to any train in a group of trains before it enters a section, via a group control center within a station. This method can be executed by a group train line data transmitting device, which can be implemented in hardware and / or software. This device can be configured in an electronic device, which can be the group control center. Figure 1A The method includes:

[0037] S110. Obtain the location information of the target train in the group train within the station yard and the real-time updated route processing information; wherein, the route processing information includes the routes that have been processed.

[0038] The Group Control Center (GCC) can be a control center or system for controlling and managing group trains. This GCC can be located in a central computer room within a station. The target train can be any train included in the group. Route processing information can be the route information of the corresponding target train processed by Computer Based Interlocking (CBI). The corresponding route can include at least one turnout and / or section within the station yard. This route can be a long route or a short route. Location information can be the location information uploaded by the target train based on the location of a preset transponder within the station yard when it passes that transponder. The preset transponder can be a positioning transponder, and its location can be set based on experience or needs. Currently processed routes can include processed routes corresponding to the target train, and can also include processed routes of other trains besides the target train.

[0039] S120. Based on the location information, the route processing information, the open status of each signal and the status of each section, determine the station line data and at least one candidate topology line corresponding to the target train, wherein different candidate topology lines correspond to the same currently processed route and different section lines.

[0040] The signal open status indicates whether the corresponding position of the signal is passable. This open status corresponds to the indicator light color, which can be green, red, or yellow. Red can be a stop signal, indicating that the train must not pass the signal; green can be a permit signal, indicating that the train can pass the signal at the prescribed speed; yellow can also be a permit signal, indicating that the train needs to slow down. The section status indicates the current operation or occupancy of the corresponding section, specifically determining whether the section is passable. This section status can include at least one of the following: idle, occupied, faulty, or route locked. Station line data can be the line data corresponding to the lines formed by the currently processed routes. The travel direction corresponding to the candidate topology line is the current travel direction of the target train, which can be actively uploaded by the target train. The starting point of each candidate topology line can be the location corresponding to the corresponding location information. Different candidate topologies can contain the same path, which can be the line formed by the currently processed routes. Each station can have at least one section, and each section can have a unique track. Different tracks have different signals installed at the corresponding section entrances in the corresponding station.

[0041] Specifically, a first mapping relationship database can be pre-established between different location information, route processing information, open status of each signal, status of each section, and station line data and at least one candidate topology line. Correspondingly, when determining the corresponding location information, route processing information, open status of each signal, and status of each section, the corresponding station line data and at least one candidate topology line can be matched by traversing the first mapping relationship database, and the matched station line data and at least one candidate topology line can be used as the station line data and at least one candidate topology line corresponding to the corresponding target train.

[0042] S130. The station line data is sent to the target train, and a unique target topology line is determined from the at least one candidate topology line based on the real-time updated route processing information and section locking conditions.

[0043] The section locking condition can be any condition that must be met to lock a section. This condition can include at least one of the following: section occupancy, section fault, associated turnout position locking, and associated turnout position fixed. The status of each section can be linked to the real-time updates of currently processed routes. Section occupancy can occur when other trains are stationed in the corresponding section or when the route corresponding to that section has already been processed by another train. The candidate topology line extension section can be the section where the target train may run, and the target topology line extension section can be the section where the target train will run. Different route processing information can correspond to different station track data.

[0044] Specifically, a second mapping relationship database can be pre-established between route processing information, section locking conditions, and candidate topology lines during the real-time update process. Correspondingly, the station route data determined before the current update can be sent to the target train. During the real-time update of the corresponding route processing information, based on the corresponding section locking conditions and the route processing information during the real-time update process, the corresponding second mapping relationship database is traversed, and each candidate topology line is matched in real-time until the matched candidate topology lines include only one candidate topology line. Then, this unique candidate topology line is taken as the corresponding target topology line. At least one of the aforementioned candidate topology lines includes all the candidate topology lines.

[0045] S140. Send the current station line data and the section line data corresponding to the target topology line to the target train.

[0046] The target topology route can be the route corresponding to the section extending from the target topology route. The section route data can be the route data corresponding to that route. The route data can include at least one of the following data types: static speed, static gradient, transponder link information, phase separation zone, track section information, and temporary speed limit information. The current station route data can be the new station route data composed of all processed routes in the updated route processing information when the corresponding target topology route is determined.

[0047] Specifically, based on the communication network associated with the station, the current station track data and the corresponding section track data of the target topology track can be sent to the corresponding target train. The stable network coverage of the communication network associated with the station can include the station and nearby sections. For example, the area that satisfies the conditions for stable communication between the train and ground equipment can include the station area and a portion of the section area connecting to the exit. The size of this portion of the section area can be set as needed and is not specifically limited here.

[0048] For easier understanding, please refer to Figure 1BThe provided examples illustrate the communication coverage area of ​​the station, the station's boundaries, and the relationships between the various sections associated with the station. It should be noted that... Figure 1B The corresponding interval settings mentioned herein are for illustrative purposes only and should not be construed as specific limitations of the present invention.

[0049] Figure 1B This is a diagram showing the relationship between the communication coverage area of ​​a station, the station area, and the areas of each section associated with the station. For example... Figure 1B As shown, the communication coverage area corresponding to the station can include the station area, a portion of the area corresponding to section 1, and a portion of the area corresponding to section 2. Here, communication coverage area can be equivalent to network coverage area. X can be the signal corresponding to the left boundary of the corresponding station, and SN can be the signal corresponding to the right boundary of the corresponding station.

[0050] In this embodiment of the invention, when a target train in a corresponding train group is within the station yard, based on the target train's location information, real-time updated route processing information, the open status of each signal, and the status of each section, the station's corresponding track data and at least one candidate topology track are determined. Furthermore, based on the corresponding real-time updated route processing information and section locking conditions, a unique target topology track is determined. This allows for the real-time determination and transmission of the target train's track data within the station, while simultaneously predicting and determining the section the target train will enter. This enables the target train to receive network signals in advance before entering areas without network coverage. The data on the lines operating within the intervals helps to solve the problems caused by "the high dependence on train control equipment and communication networks, as well as the high costs of engineering design, construction, and upgrading, caused by methods such as adding central equipment on the ground to manage and transmit the corresponding interval line data, managing and transmitting line information through ground physical equipment, or using electronic maps to fix the line data in the local memory of the onboard signal equipment, and also cannot meet the requirements for efficient storage and use of line data". It can reduce the dependence on communication networks, reduce the costs of engineering design, construction, and upgrading, while meeting the requirements for efficient storage and use of line data.

[0051] Figure 2A This is a flowchart of a group train line data transmission method according to Embodiment 2 of the present invention. This embodiment is based on the above embodiments and further optimized. It should be noted that for parts not described in detail in this embodiment, please refer to the relevant descriptions in other embodiments.

[0052] Furthermore, the step of "determining at least one candidate topology line corresponding to the target train based on the location information, the route processing information, the open status of each signal, and the status of each section" is refined to "determining the passable turnouts and sections within the station based on the open status of each signal and the status of each section; constructing an initial section route prediction tree based on the passable turnouts and sections, the location of the positioning transponder corresponding to the location information, the currently processed routes, and the locations of the section entrance signals; wherein the root node of the initial section route prediction tree is the positioning transponder, and the leaf nodes of the section route prediction tree are the turnouts and the section entrance signals; and the line corresponding to at least one path formed by the root node and each leaf node in the initial section route prediction tree is taken as at least one candidate topology line corresponding to the target train," to improve the determination mechanism of the corresponding candidate topology lines.

[0053] refer to Figure 2A The method specifically includes the following steps:

[0054] S210. Obtain the location information of the target train in the group train within the station yard and the real-time updated route processing information; wherein, the route processing information includes the routes that have been processed.

[0055] S220. Based on the open status of each signal and the status of each section, determine the passable turnouts and sections within the station.

[0056] Among them, passable turnouts and sections can be turnouts and sections within the station that allow the target train to pass.

[0057] Specifically, a correspondence can be established in advance between different open states of each signal and each section state and the passable turnouts and sections within the station yard. Accordingly, when determining the open states of each signal and each section state, the correspondence can be traversed to determine the passable turnouts and sections that match the open states of each signal and each section state, and the matched passable turnouts and sections can be used as the passable turnouts and sections within the station yard.

[0058] S230. Based on the topological relationship between each turnout and section within the station yard, an initial section route prediction tree is constructed according to the passable turnouts and sections, the location of the corresponding positioning transponder, the currently processed routes, and the location of each section entrance signal. The root node of the initial section route prediction tree is the positioning transponder, and the leaf nodes of the section route prediction tree are the turnouts and the section entrance signals.

[0059] The topological relationship between each turnout and section can be associated with the planning and design of the corresponding station yard. The positioning transponder can be any transponder with positioning function installed within the station yard. For example, the positioning transponder can be the Latest Relevant Balise Group (LRBG) currently passed by the target train. The target can upload its current location information using the nearest positioning transponder passed as a reference point. The location corresponding to a passable turnout can include the current position, reverse position, and turnout front. The initial section track prediction tree can be a section track prediction tree constructed based on the corresponding location information and currently processed routes. When the section exit signal is a leaf node of the path in the corresponding section track prediction tree, the section exit signal can be the node corresponding to the end point of that path. If the leaf nodes of the path in the corresponding section track prediction tree contain section exit signals, then the node corresponding to the end point of that path can be the termination point.

[0060] Specifically, the corresponding location transponder can be used as the root node, and each turnout included in the currently processed route can be used as a leaf node with a fixed node position. In the current running direction of the target train, starting from the turnout with the node position of the last turnout among the turnouts corresponding to the leaf nodes with the determined node positions, the next leaf node connected to the leaf node corresponding to the last turnout can be determined sequentially based on the status of each passable section and each passable turnout, until the next leaf node connected is determined to be a section gate signal or terminated.

[0061] S240. The route corresponding to at least one path formed by the root node and each leaf node in the initial section route prediction tree is taken as at least one candidate topology route corresponding to the target train; wherein, different candidate topology routes correspond to the same currently processed route and different section routes.

[0062] Specifically, based on the leaf nodes connected to the root node and the relationships between the leaf nodes, at least one path in the initial interval route prediction tree can be determined, and correspondingly, this at least one path can be used as at least one candidate topology line corresponding to the target train.

[0063] S250. The station line data is sent to the target train, and a unique target topology line is determined from the at least one candidate topology line based on the real-time updated route processing information and section locking conditions; wherein, the station line data is determined based on the location information, the route processing information, the open status of each signal and the status of each section.

[0064] For example, determining a unique target topology route from the at least one candidate topology route based on real-time updated route processing information and section locking conditions may include:

[0065] Based on the real-time updated route processing information and segment locking conditions, the paths in the initial segment route prediction tree that include hostile routes and / or satisfy the segment locking conditions are determined; based on the paths that include hostile routes and / or satisfy the segment locking conditions, the initial segment route prediction tree is pruned until a unique path exists in the pruned segment route prediction tree, and the line corresponding to the unique path is taken as the target topology line.

[0066] Specifically, a hostile route can be a route operated by a train other than the target train that interferes with or conflicts with the routes corresponding to the initial section route prediction tree. The routes corresponding to paths that satisfy the section locking condition can include at least one section that satisfies the section locking condition during the real-time update of route operation information. At least one section that satisfies the section locking condition can be determined during the real-time update of route operation information when the status of each section corresponding to the path between nodes in the initial section route prediction tree is reassessed.

[0067] Specifically, if the corresponding path in the initial section route prediction tree includes a hostile route and / or a section that meets the section locking condition, it indicates that the path cannot meet the smooth passage requirements of the target train. Accordingly, the initial section route prediction tree can be pruned based on the leaf nodes corresponding to the path, so that each path in the pruned section route prediction tree meets the smooth passage requirements of the target train. Furthermore, the initial section route prediction tree can be pruned in real-time based on updated progress information until a unique path is determined in the pruned section route prediction tree. This indicates that the section the target train will run in is definite and unique, and the line corresponding to this unique path can be used as the target topology line.

[0068] It is understandable that by determining the paths including hostile routes and / or paths satisfying the section locking conditions in the initial section route prediction tree based on the real-time updated route handling information and section locking conditions, the initial section route prediction tree can be continuously pruned to obtain the unique path corresponding to the initial section route prediction tree. This unique path is then used as the target topology line. This eliminates the need to pre-establish a mapping relationship database between different route handling information, section locking conditions, and candidate topology lines, further simplifying the determination process of the corresponding target topology line and improving the efficiency of target topology line determination. At the same time, by timely pruning the relevant data of candidate topology lines that do not meet the requirements for the smooth passage of the target train, it helps to avoid the process of continuing to acquire and send the line data corresponding to a candidate topology line when it has been determined that a candidate topology line does not meet the requirements for the smooth passage of the target train, thereby helping to reduce the waste of computing and storage resources.

[0069] S260. Send the current station line data and the section line data corresponding to the target topology line to the target train.

[0070] In one alternative implementation, the corresponding track data is received by the Automatic Train Protection (ATC) system in the target train. This track data may include station track data and section track data. It is understood that the ATC system and other equipment will use this track data to ensure safe train operation and significantly improve operational efficiency while maintaining safe operation.

[0071] In this embodiment of the invention, based on the topological relationship between each turnout and section within the station, and according to the passable turnouts and sections, the location of the corresponding positioning transponders, the currently processed routes, and the locations of the signals at each section entrance, an initial section route prediction tree is constructed, with the positioning transponders as the root node and the turnouts and section entrance signals as leaf nodes. The route corresponding to at least one path formed by the root node and each leaf node in the initial section route prediction tree is then used as at least one candidate topology route for the target train. This avoids the need to establish a relational database between the candidate topology routes and various types of data, simplifying the process of determining the candidate topology routes and improving their efficiency. Furthermore, by establishing the tree structure corresponding to the initial section route prediction tree, rapid traversal and search operations on the corresponding data are supported, and the tree structure offers high flexibility and scalability, thereby improving the efficiency of subsequent data processing when determining the target topology.

[0072] For easier understanding, please refer to Figure 2B A specific example of the station and track topology is provided. It should be noted that... Figure 2B The relevant settings of corresponding sections, transponders, sections, signals and other related line information involved are only illustrative examples and should not be construed as specific limitations of the present invention.

[0073] Figure 2B This is a topology diagram showing the relationship between a station and its corresponding railway lines. For example... Figure 2BAs shown, the corresponding station yard may include turnouts, track sections, signals, and transponders. Turnouts may include turnouts 1-12, 14, 16, and 18. Track sections within the station may include IBG, IIBG, 2-8DG, 4-6DG, 10DG, 12DG, 14DG, 16DG, 18DG, IG, IIG, 3G, 4G, 9DG, 11DG, 1-7DG, 3-5DG, IAG, and IIAG. Track sections within the station may include X1LQG-X3LQG and S1JG-S3JG. Signals within the station may include X, XN, S1-S4, X1-X4, V2, V4, V6, V8, V9, V11, V13, SN, and S. S and SN can be section intersection signals. X and XN can be the corresponding section gate signals on the left side of the station. The signals corresponding to the section lines can include 3554, 3555, 3573, and 3754, etc. The transponders installed on the lines within the station can include BS1-BS4 and BX1-BX4, etc. The transponders installed on the corresponding lines within the section can include BS, BSN, B3554, B3555, B3573, and B3754, etc. Station range 01 can be the range between signal X and signal SN, or the range between signal XN and signal S, etc. Section range 02 can start from signal SN or signal S. The line range corresponding to section line data range 03 can start from signal BSN or signal BS. The endpoint of the line range corresponding to station line data range 04 can exceed signal BSN or signal BS.

[0074] Continuing the previous example, when Train 1 reports its location to the GCC, indicating that the LRBG it has passed is transponder BX3, the GCC determines that the CBI has processed short routes X3->V9, V9->V11, and V11->SN, and that all sections are locked. At this point, the GCC can use transponder BX3 as the starting point to search for and calculate candidate topologies corresponding to the short routes X3->V9, V9->V11, and V11->SN, and calculate station line data in real time. Correspondingly, Train 1 can then use the origin and destination points within the station as... Figure 2B The red arrow indicates the station's track data. When Train 2 reports its position to GCC, indicating that the LRBG it has passed is transponder BX2, GCC determines that CBI only handles the short route corresponding to X2->V2. At this time, GCC can search and calculate candidate topologies suitable for the short route corresponding to X2->V2, starting from transponder BX2, and calculate the station's track data in real time. Correspondingly, Train 2 can operate within the station based on its origin and destination, such as... Figure 2B The green arrows indicate the station's track data. Trains 1 and 2 can both be designated as target trains.

[0075] To facilitate understanding, continuing with the previous example, you can refer to... Figure 2C Another example of the station's track topology is provided. It should be noted that... Figure 2C The relevant settings of corresponding sections, transponders, sections, signals and other related line information involved are only illustrative examples and should not be construed as specific limitations of the present invention.

[0076] Continuing from the previous example, such as Figure 2C The diagram shows the topology of the railway tracks corresponding to the station area. Corresponding turnouts may also include turnout 21, turnout 17, turnout 15, turnout 13, and turnout 19, etc. Signals corresponding to the tracks within the station may also include X5, V5, V7, V1, V3, SA, V10, V12, and SC, etc. Track sections corresponding to the tracks within the station may also include 5G, 21DG, IVAG, 17DG, 15DG, 13DG, 19DG, and IIIAG, etc. Transponders installed on the tracks within the station may also include BX5, etc. The corresponding sections of the station area may include section 1, section 2, section 3, and section 4, etc. SA can be the signal at the intersection of section 1, SN can be the signal at the intersection of section 2, S can be the signal at the intersection of section 3, and SC can be the signal at the intersection of section 4. For example, when train 1 reports its position based on transponder BX5, the station can search for all possible section points based on the reported direction of travel of train 1 and the position of the key turnout ahead, using BX5 as the starting point of the line within the station, resulting in three possible lines. Line 1 can correspond to section 1, specifically: BX5 transponder -> located turnout 21 -> SA signal; Line 2 can correspond to section 2, specifically: BX5 transponder -> reversed turnout 21 -> turnout 17 before the turnout -> turnout 9 before the turnout -> located turnout 7 -> located turnout 1 -> SN signal; Line 3 can correspond to section 3, specifically: BX5 transponder -> reversed turnout 21 -> turnout 17 before the turnout -> turnout 9 before the turnout -> reversed turnout 7 -> reversed turnout 5 -> S signal.

[0077] To facilitate understanding, continuing with the previous example, you can refer to... Figure 2D as well as Figure 2E The provided examples are the initial interval route prediction tree and the pruned interval route prediction tree. It should be noted that... Figure 2D as well as Figure 2E The related settings of the corresponding transponders, signals and turnouts involved are only illustrative examples and should not be construed as specific limitations of the present invention.

[0078] like Figure 2DThe diagram shows the structure of the initial section track prediction tree. When train 1 informs the GCC that the LRBG it is passing is transponder BX5, the GCC can use transponder BX5 as the starting point and, based on the train's reported direction of travel, search for all possible section crossings. That is, it can establish a section prediction tree with transponder BX5 as the root node and turnouts and section crossing signals as leaf nodes. The position of the turnout can include its initial position, reverse position, and before the turnout.

[0079] like Figure 2E The diagram shows the structure of the initial section route prediction tree after pruning. If the CBI does not process any routes, the GCC can simultaneously send the corresponding section markers and section transponder messages for lines 1, 2, and 3 to train 1, allowing train 1 to store the transponder message data corresponding to each section in advance. If the CBI processes the X5->V5 short route, turnout 21 can be in the reverse position. Furthermore, it can be determined that line 1 in the initial section prediction tree of train 1 no longer meets the train operation conditions, and the prediction tree can be pruned, such as... Figure 2E As shown by the dashed line on the left, only the section markers and section transponder messages corresponding to Line 2 and Line 3 are retained and sent to Train 1. If CBI processes the short route S->V8, V8->V4, V4->S2 at this time, the short route S->V8 in this sequence has a hostile route relationship with Line 3 predicted by the section prediction tree. Therefore, the section prediction tree of Train 1 can be pruned again, such as... Figure 2E As shown by the dashed line on the right, at this point, the GCC can determine that the interval prediction tree path is unique and only continues to send the interval flag and interval transponder message corresponding to line 2. After the CBI has fully processed all short routes corresponding to line 2, the GCC can send an interval confirmation message to train 1 for the train to verify the interval flag to confirm the operating interval, and continue to send the transponder message data for the remaining intervals corresponding to line 2 until all data is sent. Train operating conditions can be conditions that meet the requirements for smooth train passage.

[0080] Figure 3 This is a flowchart of a group train line data transmission method provided in Embodiment 3 of the present invention. This embodiment is based on the above embodiments and further optimized. It should be noted that for parts not described in detail in this embodiment, please refer to the relevant descriptions in other embodiments.

[0081] Furthermore, the phrase "obtaining the location information of the target train in the group of trains within the station yard" is refined to "responding to a registration request sent by the target train in the group of trains, and establishing a communication connection with the target train based on the registration request; receiving the train location information sent by the target train when it passes a preset positioning transponder, and using the train location information as the location information of the target train within the station yard; wherein the train location information is the location information of the preset positioning transponder," in order to improve the mechanism for obtaining the corresponding location information.

[0082] refer to Figure 3 The method specifically includes the following steps:

[0083] S310. In response to a registration request sent by a target train in the group of trains, establish a communication connection with the target train based on the registration request.

[0084] The registration request can be initiated by the driver of the target train or automatically sent by the target train via the corresponding ATP when it passes a preset registration transponder. The registration request can include at least the target train's identification information. This registration request can be used to request the establishment of a communication connection between the target train and the group control center. The location of the registration transponder within the station can be set as needed or based on experience. The same transponder can serve as both a registration transponder and a location transponder simultaneously.

[0085] Specifically, after receiving a registration request from the target train, the system can respond to the registration request and send a registration confirmation message back to the target train to establish a communication connection with the target train.

[0086] S320. Receive the train position information sent by the target train when it passes the preset positioning transponder, and use the train position information as the position information of the target train in the station; wherein, the train position information is the position information of the preset positioning transponder.

[0087] The preset location transponder can be a pre-installed location transponder within the station area. A pre-installed registered transponder can also serve as the preset location transponder. The location transponder can be used to indicate the current location of the target train.

[0088] S330. Obtain real-time updated route processing information; wherein, the route processing information includes routes that have already been processed.

[0089] S340. Based on the location information, the route processing information, the open status of each signal and the status of each section, determine the station line data and at least one candidate topology line corresponding to the target train, wherein different candidate topology lines correspond to the same currently processed route and different section lines.

[0090] S350. The station line data is sent to the target train, and a unique target topology line is determined from the at least one candidate topology line based on the real-time updated route processing information and section locking conditions.

[0091] For example, after determining the station track data corresponding to the target train and at least one candidate topology line, the process may further include:

[0092] The route data for each section corresponding to at least one candidate topology route is sent to the target train so that the target train can pre-store the route data for each section; if the target topology route is determined, the sending of route data for the sections corresponding to other candidate topology routes other than the target topology route is cancelled.

[0093] Specifically, after identifying at least one candidate topology line, all section line data corresponding to that candidate topology line can be pre-sent to the target train, allowing the target train to store the pre-sent section line data for future use. Furthermore, after identifying the target topology line, the transmission of section line data corresponding to other candidate topology lines can be cancelled, maintaining only the transmission of section line data corresponding to the target topology line.

[0094] Understandably, by sending the section line data corresponding to all candidate topology lines to the target train for storage and backup before determining the target topology line, it is possible to effectively avoid the situation where the target train cannot fully receive the section line data corresponding to the section it is about to travel when the section line data transmission is not yet completed when the target train leaves the network coverage area of ​​the station. This greatly improves the timing of the completion of line data transmission and helps to reduce the requirements for section network coverage.

[0095] For example, after determining the target topology, it can be first determined whether the section line data corresponding to other candidate topologies outside the target topology has been completely transmitted. Accordingly, if yes, the target train can be controlled to delete the pre-stored section line data corresponding to other candidate topologies outside the target topology; if no, the transmission of the section line data corresponding to other candidate topologies outside the target topology can be canceled, and the section line data corresponding to other candidate topologies outside the target topology that have been stored in the target train can be deleted.

[0096] S360. Send the current station line data and the section line data corresponding to the target topology line to the target train.

[0097] In one optional embodiment, sending the section line data to the target train may include:

[0098] The section line data is sent to the target train in the form of transponder group messages, so that the target train can activate the corresponding section line data after passing the physical transponder on the section line corresponding to the target topology line; wherein, each group of transponder group messages corresponds to a group of ground physical transponders.

[0099] Each transponder group may contain at least one transponder group message, which can describe one or more types of line data within the jurisdiction of that transponder group. A physical transponder may be a transponder installed at a predetermined location on the line section. The predetermined location can be set as needed, and there may be at least one group of physical transponders. The physical transponder may contain a corresponding transponder group message used for location and to authorize trains to use the line section data. This physical transponder may not contain the line section data and may not transmit the line section data.

[0100] This can be understood as follows: when the target train is within the network coverage area of ​​the station, the corresponding section line data is first sent to the target train in the form of transponder group messages. Each transponder group message is associated with a ground physical transponder, so that the physical transponders laid on the corresponding section line do not need to undertake the function of transmitting or storing section line data, but only perform the functions of positioning and allowing the train to use the transponder group messages in the section line data. This helps to avoid the situation where the design, construction, management and update costs are high due to the deployment of a large amount of line data in the ground physical equipment on the section line, and thus helps to meet the requirements of efficient storage and use of line data.

[0101] In one optional embodiment, the station-internal line data and the section line data corresponding to the station may have overlapping parts, and the station-internal line data corresponding to the overlapping part may pass through the starting point of the section line corresponding to the section line data.

[0102] The starting point of the section line can be the location corresponding to the first transponder group in the direction of the target train's travel in the current section. The station line data and the section line data can overlap, indicating that the lines corresponding to the station line data and the lines corresponding to the section line data share a common portion. This common portion can be the line corresponding to the overlapping section.

[0103] Understandably, by ensuring that there is an overlap between the corresponding station line data and the section line data, and that the line corresponding to this overlap passes through the starting point of the corresponding section line, it is possible to avoid the situation where the section line data starting from the section entrance transponder group cannot describe the data of the gap between the section entrance transponder group and the actual station boundary, which is caused by the section transponder being set outside the exit. This helps to ensure that the line data received by the target train can cover the entire line.

[0104] In this embodiment of the invention, a communication connection is first established with the target train through a registration request sent by the target train. Then, based on this communication connection, the train position information sent by the target train when it passes a preset positioning transponder is used as the current position information of the target train. This ensures that the information sent by the target train is received based on a specific communication connection after the target train has actually registered. This helps to avoid the situation of mistakenly receiving information from other trains or failing to find the target train in time, thereby improving the accuracy and timeliness of receiving and sending the corresponding information of the target train. At the same time, by enabling the target train to report its own position information based on the position of the preset positioning transponder when it passes the preset positioning transponder, it helps to grasp the position of the target train in a timely manner and determine and obtain the corresponding route data based on the position of the target train, thereby helping to further advance the timing of the completion of the transmission of the corresponding route data.

[0105] Figure 4 This is a schematic diagram of a group train line data transmission device provided in Embodiment 4 of the present invention. This embodiment is applicable to transmitting line data to any train in a group before it enters the section, via a group control center within a station. The device can be implemented in hardware and / or software and can be configured in an electronic device, which can be the group control center. Figure 4 The device includes:

[0106] The location and route information acquisition module 410 is used to acquire the location information of the target train in the group train within the station yard and the real-time updated route processing information; wherein, the route processing information includes the routes that have been processed.

[0107] The candidate topology route determination module 420 is used to determine the station line data and at least one candidate topology route corresponding to the target train based on the location information, the route processing information, the open status of each signal and the status of each section. Different candidate topology routes correspond to the same currently processed route and different section lines.

[0108] The target topology route determination module 430 is used to send the station line data to the target train and determine a unique target topology route from the at least one candidate topology route based on the real-time updated route handling information and section locking conditions.

[0109] The line data sending module 440 is used to send the current station line data and the section line data corresponding to the target topology line to the target train.

[0110] In this embodiment of the invention, when a target train in a corresponding train group is within the station yard, based on the target train's location information, real-time updated route processing information, the open status of each signal, and the status of each section, the station's corresponding track data and at least one candidate topology track are determined. Furthermore, based on the corresponding real-time updated route processing information and section locking conditions, a unique target topology track is determined. This allows for the real-time determination and transmission of the target train's track data within the station, while simultaneously predicting and determining the section the target train will enter. This enables the target train to receive network signals in advance before entering areas without network coverage. The data on the lines operating within the intervals helps to solve the problems caused by "the high dependence on train control equipment and communication networks, as well as the high costs of engineering design, construction, and upgrading, caused by methods such as adding central equipment on the ground to manage and transmit the corresponding interval line data, managing and transmitting line information through ground physical equipment, or using electronic maps to fix the line data in the local memory of the onboard signal equipment, and also cannot meet the requirements for efficient storage and use of line data". It can reduce the dependence on communication networks, reduce the costs of engineering design, construction, and upgrading, while meeting the requirements for efficient storage and use of line data.

The root node of the initial section route prediction tree is the positioning transponder, and the leaf nodes of the section route prediction tree are the turnouts and the section entrance signals.

[0114] The candidate topology route determination unit is used to take the route corresponding to at least one path formed by the root node and each leaf node in the initial interval route prediction tree as at least one candidate topology route corresponding to the target train.

[0115] Optionally, the target topology determination module 430 may include:

[0116] The path determination unit is used to determine, based on the real-time updated route processing information and the section locking conditions, the paths in the initial section route prediction tree that include hostile routes and / or satisfy the section locking conditions.

[0117] The target topology route determination unit is used to prune the initial interval route prediction tree based on the path including the hostile route and / or the path that satisfies the segment locking condition, until there is a unique path in the pruned interval route prediction tree, and then take the route corresponding to the unique path as the target topology route.

[0118] Optionally, the location and route information acquisition module 410 may include:

[0119] A communication connection establishment unit is used to respond to a registration request sent by a target train in a group of trains, and to establish a communication connection with the target train based on the registration request;

[0120] A location information receiving unit is used to receive train location information transmitted by the target train when it passes a preset positioning transponder, and to use the train location information as the location information of the target train within the station; wherein the train location information is the location information of the preset positioning transponder.

[0121] Optionally, the corresponding device may also include:

[0122] The line data pre-storage module is used to send the section line data corresponding to the at least one candidate topology line to the target train after determining the station line data and at least one candidate topology line corresponding to the target train, so that the target train can pre-store the section line data.

[0123] The line data cancellation module is used to cancel the transmission of section line data corresponding to other candidate topologies other than the target topology line if the target topology line is determined.

[0124] Optionally, sending the section route data to the target train may include:

[0125] The section line data is sent to the target train in the form of transponder group messages, so that the target train can activate the corresponding section line data after passing the physical transponder on the section line corresponding to the target topology line; wherein, each group of transponder group messages corresponds to a group of ground physical transponders.

[0126] Optionally, the station-internal line data and the section line data corresponding to the station can have overlapping parts, and the lines corresponding to the overlapping parts can pass through the starting point of the section line corresponding to the section line data.
