Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of rail transit dispatching centralized control, and in particular to a group train route triggering method and system. Background Art

[0002] With the development of technology, the control mode of rail transit is becoming more and more automated.

[0003] Currently, traditional train route triggering is typically performed on a per-train basis. This traditional approach often uses a single signal to reflect the triggering status of the entire train route from the station entrance to the track. Train drivers must monitor the signal to confirm whether the train route has been triggered and control the train to wait or enter the route based on the signal.

[0004] However, this traditional train route triggering method requires triggering the route of each train, resulting in a large number of repeated and redundant route triggering operations, and also requires manual viewing of light signals, which is time-consuming and labor-intensive, and may also result in human errors. Summary of the Invention

[0033] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] Example 1

[0036] Figure 1 A flow chart of a group train route triggering method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of group train route triggering. The method can be executed by a group train route triggering system. The group train route triggering system can be implemented in the form of hardware and / or software. Figure 1 As shown, the method includes:

[0037] S110. Obtain the operation plans of multiple current trains through the scheduling centralized control module, generate a route sequence corresponding to each current train based on the operation plan, and send the route sequence to the group control center module.

[0038] Among them, the centralized dispatching control module may refer to Centralized Traffic Control, or CTC for short. The centralized dispatching control module can connect stations and sections (sub-routes) in series to form a complete line display diagram. The centralized dispatching control module also includes a CTC control and display terminal, which is used to display the location information and operation plan of each signal device (such as a signal light) and each train at each station. The current train may refer to multiple trains that need to enter or exit the station within a preset time period. The operation plan may refer to the train travel plan. The operation plan may include but is not limited to the train travel path including the expected travel time period. The operation plan may be issued by the dispatcher through the dispatching console. The route may refer to the path that the train needs to travel from one location to another in the station. The route can be understood as the train travel path. The route sequence can serve as the basis for train formation. The route sequence may refer to the train route and train group information preliminarily divided according to the operation plan. The train group information may refer to the group information to which the train belongs to which is preliminarily divided.

[0039] Specifically, the centralized dispatching control module obtains the operation plans of multiple current trains and determines that current trains with the same route in the operation plan belong to the same train group. Based on the line display diagram, the route of each current train in the operation plan is segmented to obtain multiple sub-routes corresponding to each current train, thereby generating a route sequence corresponding to each current train and sending the route sequence to the group control center module. In this embodiment of the present invention, current trains with the same route are organized into the same train group. When the group train enters the station, only the first train is triggered to enter the station, and subsequent trains do not need to trigger the station entry again, further improving the efficiency of group train entry triggering. All sub-routes of each current train can be combined into a sub-route list corresponding to the current train, and the sub-route list can be displayed on the CTC control and display terminal. When the current train passes through a sub-route section, the sub-route section can be automatically transferred to the "cleared" state, indicating that the current train has completed the route. If all sub-routes corresponding to the current train are in the "cleared" state, it indicates that the current train has completed the route and arrived at the desired destination. You can also mark the trains that have not triggered the route as "waiting for triggering" and mark the trains that have successfully triggered the route as "trigger completed".

[0040] Based on the above technical solution, the operation plan includes: the route information and train attributes corresponding to each current train; the route information includes: the path entering the station and / or the path leaving the station and the track; the route sequence includes: the sub-route and target group information corresponding to the current train.

[0041] Among them, the route can be subdivided into the path entering the station and / or the path leaving the station and the track. The track can refer to the numbered track in the station. The track can be used to determine the specific location of the train stop. The track can be located between the path entering the station and the path leaving the station. The complete route of the current train is the main route. The main route can be divided into multiple sub-routes based on the intervals controlled by the virtual signals in the station. The interval refers to the path between adjacent virtual signal transmission positions, that is, the interval can be understood as a sub-route. The target group information may refer to the group information to which the train belongs obtained by the preliminary division. For example, the first three current trains belong to the first group of trains, and the next two current trains belong to the second group of trains.

[0042] On the basis of the above technical solution, "generating a route sequence corresponding to each current train based on the operation plan through the scheduling centralized control module" may include: grouping the current trains with the same entry path or exit path into the station based on the route information of each current train through the scheduling centralized control module to obtain the candidate group information corresponding to each current train; eliminating the current trains with train attributes that cannot be grouped in the candidate group information based on the train attributes through the scheduling centralized control module to obtain the target group information corresponding to each current train; determining the sub-route corresponding to the current train based on the route information and the line display diagram corresponding to the target station through the scheduling centralized control module.

[0043] Among them, the information of the selected group may refer to the information of the group to which trains with similar routes are preliminarily screened based on the train route. The train attribute may refer to the pre-set attribute of whether the train can be grouped. The target group information may refer to the information of the group to which the train belongs obtained by screening based on the train route and train attributes. In an embodiment of the present invention, trains with the same path entering the station or the same path leaving the station, regardless of whether the tracks are the same, are divided into the same group. This ensures that the sub-routes in the same group except the tracks are the same. When the group train route is triggered, it can ensure that the vast majority of sub-routes (other sub-routes except the tracks) are triggered only once. While ensuring the efficiency of the route triggering, the number of current trains in the same group trains is expanded, further improving the versatility and efficiency of the group train depot triggering.

[0044] Specifically, the centralized dispatching control module groups the current trains that have the same entry or exit path into the station based on the route information of each current train, and obtains the candidate group information corresponding to each current train. At this time, the tracks of the current trains corresponding to the same candidate group information can be the same or different. The centralized dispatching control module eliminates the current trains whose train attributes are non-groupable from the candidate group information based on the train attributes, and obtains the target group information corresponding to each current train. The centralized dispatching control module segments the route information of each current train based on the line display diagram corresponding to the target station, determines the sub-route corresponding to each current train, and can trigger each sub-route separately.

[0045] S120. The group control center module performs train marshaling on multiple current trains based on the received route sequence to determine the train marshaling result, and sends the train marshaling result to the dispatching centralized control module.

[0046] The group control center module may refer to the GNU Compiler Collection, or GCC for short. The group control center module is used to implement train marshaling, thereby virtually grouping multiple physically independent trains into groups through vehicle-to-vehicle ad hoc networking technology to form a group train. The train marshaling result may refer to whether the current train is marshaled into a group train according to the target group information corresponding to the current train in the route sequence, i.e., the target group information to which the current train belongs. In an embodiment of the present invention, trains in the same group can be considered as a single train, thereby effectively improving the train reception and dispatching efficiency and operation density of existing lines.

[0047] Specifically, the group control center module for each current train performs train formation on the current train based on the sub-route and target group information corresponding to the current train in the received route sequence, and determines the train formation result corresponding to each current train. The group control center module for each current train sends the train formation result corresponding to the current train to the dispatching centralized control module.

[0048] On the basis of the above technical solution, "determining the train marshaling result by performing train marshaling on multiple current trains based on the received route sequence through the group control center module" may include: performing marshaling verification on the current train based on a preset verification method through the group control center module to obtain a verification result; if the verification result through the group control center module is that the current train is allowed to be marshaled, a group train is formed using the self-organizing network, and a train marshaling success result is generated; if the verification result through the group control center module is that the current train refuses to be marshaled, the current train is determined to be an ordinary train, and a train marshaling failure result is generated.

[0049] The preset verification method may refer to a method that pre-determines whether the current train is suitable for marshaling within a preset time period. For example, the preset verification method may include, but is not limited to, a driver's manual determination of whether the current train is suitable for marshaling, or a determination based on the train's current operating status. Verification results may include the current train allowing marshaling or the current train rejecting marshaling. Verification results have a veto power. A train marshaling success result may refer to the current train being successfully marshaled. An ordinary train may refer to a train that does not participate in marshaling, i.e., a separate train.

[0050] Specifically, through the group control center module of the current train, the current train is subjected to a marshaling check based on a preset check method. If it is verified that the current train can be marshaled according to the target group information in the route sequence, the check result corresponding to the current train is determined as the current train is allowed to be marshaled. If it is verified that the current train cannot be marshaled according to the target group information in the route sequence, the check result corresponding to the current train is determined as the current train is refused to be marshaled. Through the group control center module of the current train, if the check result of the current train is that the current train is allowed to be marshaled, the current train is incorporated into the target group to form a group train based on the target group information and self-organizing network technology. Through the group control center module of the current train, if the check result of the current train is that the current train is refused to be marshaled, the inclusion is refused and the current train is determined to be an ordinary train, and a train marshaling failure result is generated.

[0051] S130. The scheduling centralized control module determines the track similarity between adjacent trains in the group train based on the received train formation results and route sequence, and determines the state adjustment strategy corresponding to the sub-route of each target train in the group train based on the track similarity, and sends the state adjustment strategy to the computer interlocking module and the group control center module.

[0052] Among them, track similarity may refer to the degree of similarity between the tracks where the trains stop. For example, track similarity may be the same track and different track. The target train may refer to the current train in the group train. The target train may be a non-ordinary train. The state adjustment strategy may refer to the state adjustment strategy of the sub-route before and after each train passes through the sub-route. The state adjustment strategy may be understood as a state adjustment instruction. For example, the state adjustment strategy may include: sub-route blocking strategy and sub-route unblocking strategy. The state of the sub-route can be used to reflect whether the train has successfully triggered the route. The state of the sub-route may include but is not limited to whether the signal of the signal device in the sub-route is adjustable, that is, whether the signal device is locked, whether the sub-route is enterable, and the current occupation status of the sub-route. For example, when the state of the sub-route is that the signal device is locked, the sub-route is enterable, and the sub-route is not occupied, the train has successfully triggered the route and can enter the sub-route.

[0053] Specifically, the dispatching centralized control module determines the group train composed of the current train belonging to the same train group information based on the current train that has successfully formed the current train according to the train formation result and the target group information in the route sequence, and determines the track similarity between adjacent trains in the group train based on the sub-route corresponding to the current train in the route sequence. The dispatching centralized control module can trigger the tracks corresponding to all target trains in the group train when the route of the first car in the group train is triggered, thereby determining the sub-route blocking strategy corresponding to the group train, and unblocking the sub-route when the last car in the group train leaves the sub-route, thereby determining the sub-route unblocking strategy corresponding to the group train, and sending the status adjustment strategy to the computer interlocking module and the group control center module. The status adjustment strategy of ordinary trains can be set by the dispatcher according to the route sequence.

[0054] On the basis of the above technical solution, "determining the track similarity between adjacent trains in a group train based on the received train formation results and route sequence through the scheduling centralized control module" may include: if the train formation result is a successful train formation result, then determining the group trains belonging to the same formation based on the train formation result and the route sequence through the scheduling centralized control module, and determining the track similarity between adjacent trains in the group train based on the route sequence.

[0055] Specifically, the scheduling centralized control module determines the group train composed of the current train belonging to the same train group information based on the train formation result, the current train corresponding to the current train formation successfully, and the target group information in the route sequence, and determines the track similarity between adjacent trains in the group train based on the sub-route corresponding to the current train in the route sequence.

[0056] S140. The computer interlocking module controls the current sub-route triggering in the target station based on the received state adjustment strategy to determine the sub-route triggering result, and sends the sub-route triggering result to the group control center module.

[0057] Among them, the computer interlocking module may refer to an interlocking function module that controls the signal equipment in the station, including switches, sections, signals, and the safety interlocking relationship between switches, signals, and track circuits in the constrained route. In an embodiment of the present invention, the computer interlocking module can be used to adjust the status of the sub-route. The control range of a computer interlocking module is one station. The target station may refer to the station that the current train wants to enter or exit. The current sub-route may refer to the sub-route corresponding to the train that triggers the route. The sub-route trigger result may include a trigger success result or a trigger failure result corresponding to each sub-route. In the case where the sub-route is occupied, blocked by other group trains or ordinary trains, or disabled due to a fault, the sub-route trigger result of the train currently triggering the route is a trigger failure result. If the trigger fails, the sub-route can be triggered again after a preset time period. When the number of failed triggers of the same sub-route corresponding to a group train reaches a preset failure threshold, an alarm can be issued and the system can be transferred to manual operation.

[0058] Specifically, the computer interlocking module triggers the current sub-route for trains at different positions in the group train based on the state adjustment strategy. For example, when the first train in the group train triggers the route, the tracks corresponding to all target trains in the group train are also triggered. This determines the sub-route triggering results for each group train and sends them to the group control center module.

[0059] S150. Control the target train to enter the current sub-route based on the received sub-route trigger result through the group control center module, and adjust the current state of the current sub-route based on the received state adjustment strategy and the current position information of the target train.

[0060] The current location information may refer to the location information to which the train is traveling at the current moment.

[0061] Specifically, if the sub-route trigger result is a successful trigger result, the group control center module controls the target train to enter the current sub-route that was successfully triggered. Based on the received state adjustment strategy, the group control center module unblocks the sub-route when the last train in the group train exits the current sub-route, that is, adjusts the current sub-route from a blocked state to an unblocked state, thereby improving the route trigger success rate of the next train (another group train or a regular train).

[0062] The technical solution of the embodiment of the present invention is to obtain the operation plans of multiple current trains through the scheduling centralized control module, and generate the route sequence corresponding to each current train based on the operation plan, and send the route sequence to the group control center module; the group control center module performs train grouping on multiple current trains based on the received route sequence to determine the train grouping result, and send the train grouping result to the scheduling centralized control module; the scheduling centralized control module determines the track similarity between adjacent trains in the group train based on the received train grouping result and the route sequence, and determines the state adjustment strategy corresponding to the sub-route of each target train in the group train based on the track similarity, and sends the state adjustment strategy to the computer interlocking module and the group control center module; The interlocking module controls the current sub-route triggering in the target station based on the received state adjustment strategy to determine the sub-route triggering result, thereby realizing unified route triggering of the group trains, avoiding repeated route triggering of the group trains, improving the train route triggering efficiency, and sending the sub-route triggering result to the group control center module; the group control center module controls the target train to enter the current sub-route based on the received sub-route triggering result, and adjusts the current state of the current sub-route based on the received state adjustment strategy and the current position information of the target train, thereby realizing the flow adjustment of the sub-route state corresponding to each target train in the group train, improving the sub-route triggering efficiency between each train in the group train, and improving the overall train route driving efficiency of the group train.

[0063] On the basis of the above technical solution, the method also includes: if the train formation result is a train formation failure result, the state adjustment strategy corresponding to the main approach of the ordinary train is determined based on the route sequence of the ordinary train through the scheduling centralized control module, and the state adjustment strategy is sent to the computer interlocking module; the computer interlocking module controls the signal corresponding to the main approach of the ordinary train based on the received state adjustment strategy, adjusts the main approach state to a closed state before the ordinary train enters the main approach, and adjusts the main approach state to an unsealed state when the ordinary train exits the main approach.

[0064] Among them, for group trains, the computer interlocking module uses virtual signals to reflect the status of sub-routes; virtual signals are logical signals that are not visible outdoors; for ordinary trains, the computer interlocking module uses actual signals sent by signal machines to reflect the status of main routes; actual signals are lighting signals that are visible outdoors.

[0065] Specifically, the scheduling centralized control module triggers the main route for a complete route corresponding to an ordinary train, i.e., the main route, thereby generating a state adjustment strategy for the main route corresponding to the ordinary train, and sending the state adjustment strategy to the computer interlocking module. The state adjustment strategy for the main route can be that when triggering the main route corresponding to an ordinary train, the main route needs to be treated as a whole, and the state of the main route, i.e., the trigger result, is displayed using the signal in front of the main route. The computer interlocking module controls the signal corresponding to the main route of the ordinary train based on the received state adjustment strategy, adjusts the state of the main route to a closed state before the ordinary train enters the main route, and adjusts the state of the main route to an unsealed state when the ordinary train exits the main route.

[0066] Example 2

[0067] Figure 2 This is a flow chart of a group train route triggering method provided by the second embodiment of the present invention. This embodiment describes in detail the process of determining the state adjustment strategy based on the above embodiment. The explanations of the terms that are the same or corresponding to the above embodiments are not repeated here. Figure 2 As shown, the method includes:

[0068] S210. Obtain the operation plans of multiple current trains through the scheduling centralized control module, generate a route sequence corresponding to each current train based on the operation plan, and send the route sequence to the group control center module.

[0069] S220, performing train marshaling on multiple current trains based on the received route sequence through the group control center module to determine a train marshaling result, and sending the train marshaling result to the dispatching centralized control module;

[0070] S230. Determine, through the dispatching centralized control module, the track similarity between adjacent trains in the group train based on the received train formation result and route sequence.

[0071] S240. Through the scheduling centralized control module, if the track of the previous train in adjacent trains is the same as the track of the next train, the sub-route state before the next train enters the sub-route is controlled to be consistent with the sub-route state before the previous train enters, and a first adjustment strategy is generated.

[0072] The advantage of this setup is that, if the routes of the preceding and succeeding trains are identical, only the preceding train needs to trigger its route, while the succeeding train can maintain the preceding train's route trigger state. This improves the efficiency of group train route triggering. Furthermore, if all target trains in a group have the same route, only one route trigger for the first train is required, regardless of the number of target trains in the group.

[0073] S250. If the previous train is the first train in the group of trains, the sub-route state before the previous train enters the sub-route is adjusted to a closed state through the scheduling centralized control module, and a second adjustment strategy is generated.

[0074] The closed state prevents other group trains and regular trains from entering. This closed state is released by the group control center module. Each active train has a corresponding group control center module. This setting has the advantage of preventing congestion or collisions caused by other group trains or regular trains cutting in line when a group train enters or exits a station, further improving group train operation efficiency.

[0075] S260. If the following train is the last train in the group train, the sub-route state of the following train when it leaves the sub-route is adjusted to an unblocked state through the dispatching centralized control module, and a third adjustment strategy is generated.

[0076] The unblocked state can refer to a state where other group trains and ordinary trains can enter. The advantage of this setting is that when all group trains have left the sub-route, the blocked state of the sub-route can be automatically released, so that other group trains or ordinary trains can effectively trigger the sub-route, avoiding the need to transmit data back to the dispatching centralized control module and then issue a release instruction through the dispatching centralized control module, thereby improving the overall operating efficiency of the current train.

[0077] S270. If the track of the preceding train and the track of the succeeding train among adjacent trains are different, the track state of the preceding train when it leaves the track is adjusted to an unblocked state through the dispatching centralized control module, and a fourth adjustment strategy is generated.

[0078] Among them, when the track of the previous train is different from that of the next train, the status of the sub-route is adjusted only for different sub-routes, that is, tracks, and there is no need to repeatedly trigger the same sub-route, that is, the path out of the station or the path into the station, which reduces the number of repeated sub-route triggering in the group train and further improves the route triggering efficiency of the group train.

[0079] S280. Determine the state adjustment strategy corresponding to the sub-route of each target train in the group train through the scheduling centralized control module based on the first adjustment strategy, the second adjustment strategy, the third adjustment strategy and the fourth adjustment strategy, and send the state adjustment strategy to the computer interlocking module and the group control center module.

[0080] S290. The computer interlocking module controls the current sub-route triggering in the target station based on the received state adjustment strategy, determines the sub-route triggering result, and sends the sub-route triggering result to the group control center module.

[0081] S2100. Control the target train to enter the current sub-route based on the received sub-route trigger result through the group control center module, and adjust the current state of the current sub-route based on the received state adjustment strategy and the current position information of the target train.

[0082] The technical solution of the embodiment of the present invention is that, if the track of the preceding train and the following train in adjacent trains are the same, the sub-route state of the following train before entering the sub-route is controlled to be consistent with the sub-route state before the preceding train enters, and a first adjustment strategy is generated. Therefore, when the routes of the preceding train and the following train are exactly the same, only the preceding train needs to trigger the route, and the following train does not need to trigger the route, and the route trigger state of the preceding train can be maintained, thereby improving the efficiency of group train route triggering. Furthermore, if the routes of all target trains in a group train are the same, only one first train route trigger is required regardless of the number of target trains in the group train. If the preceding train is the first train in the group train, the sub-route state of the preceding train before entering the sub-route is adjusted to a closed state, and a second adjustment strategy is generated. This closed state can prevent other group trains or ordinary trains from cutting in line when a group train enters or exits a station, causing congestion or collision, further improving the operating efficiency of the group train. If the subsequent train is the last train in the group train, the dispatching centralized control module adjusts the sub-route status to an unblocked state when the subsequent train exits the sub-route, and generates a third adjustment strategy. This allows other group trains or ordinary trains to effectively trigger the sub-route, avoiding the need to transmit data back to the dispatching centralized control module and then issue a release command through the dispatching centralized control module, thereby improving the overall operating efficiency of the current train. If the track of the preceding train in the adjacent train is different from the track of the following train, the dispatching centralized control module adjusts the track status of the preceding train when it exits the track to an unblocked state, and generates a fourth adjustment strategy. Therefore, when the track of the preceding train is different from the track of the following train, the sub-route status adjustment is only performed for different sub-route, eliminating the need to repeatedly trigger the same sub-route, reducing the number of repeated sub-route triggering within the group train and further improving the group train route triggering efficiency. The dispatching centralized control module determines the sub-route status adjustment strategy corresponding to each target train in the group train based on the first adjustment strategy, the second adjustment strategy, the third adjustment strategy, and the fourth adjustment strategy.

[0083] For example, Figure 3 Give an example diagram of a target station. Figure 3, signal position S is located at the entrance of the target station, signal position XN is located at the exit of the target station, S, LS1, LS2, XI, XII, SII, SI, LX1, LX2 and XN can all send virtual signals, S, SII and SI can send actual signals, IIG and IG are tracks, the section between S and LS1 is a sub-approach, and so on, the section between LX2 and XN is a sub-approach, between S and XI is a main approach, and so on, between SI and XN is a main approach. Figure 3 Based on the above, an embodiment of the present invention further provides a method for triggering a priority group train route. The method includes: processing a train operation plan, triggering a common train route, triggering a group lead train route, and triggering a group follower train route.

[0084] Processing train operation plans involves the group train route trigger system receiving the train operation plan from the dispatching console and generating a route sequence based on the plan. The route sequence is fed back to the CTC control and display interface, which displays a list of virtual signal subroutes included in the receiving and dispatching routes and information about the group to which the train belongs. The route sequence is initially in the "waiting for trigger" state.

[0085] Triggering ordinary train routes includes: When the group train route trigger system determines that the train is not a group train based on the train formation results, it triggers route S-XI and the system opens the actual signal S. Ordinary train routes do not allow manual segmented triggering (such as segmenting S-XI into S-LS1, LS1-LS2, and LS2-XI for segmented triggering) to prevent the erroneous opening of virtual signals. Only the main route S-XI can be triggered. If any sub-route (S-LS1, LS1-LS2, and LS2-XI) does not meet the triggering conditions, it is not allowed to be triggered.

[0086] Triggering the group's first train route involves: When the group train route triggering system determines that a train is the first train in the group based on the planned train formation, it triggers the virtual signal sub-routes in sequence, from closest to furthest, according to the rule that each sub-route is triggered when a trigger condition is met. After the triggering is complete, the route enters the closed state ("trigger completed"). Signals S, LS1, and LS2 are all virtual signals.

[0087] It should be noted that this step can be triggered manually. When manually triggered, the system control does not trigger the actual signal route. Manual triggering supports two methods: (1) Manually trigger the main route S-XI. At this time, the system will not trigger S-XI, but will check each sub-route in the route in order from near to far, and trigger them one by one if they meet the conditions until a sub-route that does not meet the conditions is encountered. Sub-routes that temporarily do not meet the conditions can be manually triggered later at an appropriate time. (2) Manually trigger a single sub-route. The system only checks the triggering conditions of the sub-route, and triggers the sub-route if the conditions are met.

[0088] Triggering a group's follower route involves: After the group's first train passes through the virtual signal route, the sub-route sequence automatically transitions to the "Clear" state. Simultaneously, the corresponding sub-route sequence for the next train in the group is set to the "Trigger Completed" state. This means the next train's route matches the preceding train's, eliminating the need for further triggering and directly inheriting its route. Once all sub-routes within the preceding train's route sequence are cleared, the route sequence is automatically deleted.

[0089] Train groups allow the following train (the trailing train) to follow a different track from the leading train (the leading train). If the following train's track differs from the leading train's, the group control center module automatically unlocks the virtual signal sub-route that differs from the trailing train's path after the leading train passes. After unlocking, it enters the "waiting for trigger" state. Virtual signal sub-routes with the same path remain in the "trigger complete" state, indicating an open signal. If the system determines that the trailing train's route cannot be inherited, it automatically triggers the trailing train's sub-route. After triggering, it forms a complete entry and exit route together with the inherited sub-route. For example, the leading train uses the IG receiving route S-XI, and the trailing train uses the IIG receiving route S-XII. The first two sub-routes of both routes are S-LS1 and LS1-LS2, but the third sub-route differs. After the leading train passes, the LS2-XI route is unlocked, and the trailing train must independently trigger the LS2-XII sub-route. The route sequence for the last train in the group is automatically deleted after the train passes.

This system and the group train route triggering methods of the above-mentioned embodiments belong to the same inventive concept.
