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

[0003] At present, the traditional train route triggering is usually for a single train. This traditional train route triggering method often uses a signal light signal to reflect the triggering status of the entire route of the train from the station entrance to the track, and the train driver needs to watch the signal light signal to confirm whether the train route is triggered, and control the train to wait or enter the route according to the light 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.

[0035] Embodiment 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, obtaining the operation plans of multiple current trains through the dispatching centralized control module, generating a route sequence corresponding to each current train based on the operation plan, and sending the route sequence to the group control center module.

[0038] Among them, the dispatching centralized control module may refer to Centralized Traffic Control, referred to as CTC. The dispatching centralized control module can connect stations and sections (sub-routes) in series to form a complete line display diagram. The dispatching centralized control module also includes a CTC control and display terminal for displaying each signal device (such as a signal machine) at each station, the location information of each train, and the operation plan. 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 a 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 desk. 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 operation plans of multiple current trains are obtained through the dispatching centralized control module, and the current trains with the same route in the operation plan are determined to belong to the same train group information, and the route of each current train in the operation plan is segmented based on the line display diagram 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 an embodiment of the present invention, the current trains with the same route are marshaled into the same formation to form a group train, and when the group train approaches, only the first train is triggered to enter the station, and subsequent trains do not need to repeatedly trigger the entry, which further improves the efficiency of the group train entry trigger. All sub-routes of each current train can form a sub-route list corresponding to the current train, and the sub-route list is displayed on the CTC control and display terminal, and when the current train passes through a certain section of the sub-route, the section of the sub-route can be automatically transferred to the "clear" state, that is, it is used to indicate that the current train has completed the section of the sub-route. If all the sub-routes corresponding to the current train are in the "clear" state, it means that the current train has completed the route travel and arrived at the desired location. 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: route information and train attributes corresponding to each current train; route information includes: path entering the station and / or exiting the station and track; route sequence includes: 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 after 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 dispatching 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 dispatching 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 dispatching 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 dispatching centralized control module.

[0043] Among them, the information of the selected group may refer to the information of the group to which the trains with similar routes are preliminarily screened based on the train routes. 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 entry or exit path to the station, regardless of whether the tracks are the same, are divided into the same group, which can ensure that the other sub-routes except the tracks in the same group are the same. When the group train route is triggered, it can ensure that most of the 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 of trains is expanded, further improving the versatility and efficiency of the group train depot triggering.

[0044] Specifically, the current trains with the same entry or exit path to the station are grouped based on the route information of each current train through the centralized dispatching control module, and the selected group information corresponding to each current train is obtained. At this time, the tracks of the current trains corresponding to the same group information to be selected can be the same or different. The current trains with train attributes that cannot be grouped in the selected group information are eliminated based on the train attributes through the centralized dispatching control module, and the target group information corresponding to each current train is obtained. The route information of each current train is segmented based on the line display diagram corresponding to the target station through the centralized dispatching control module, and the sub-route corresponding to each current train is determined, so that each sub-route can be triggered 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] Among them, the group control center module may refer to the GNU Compiler Collection, referred to as GCC. The group control center module is used to implement train marshaling, so that multiple physically independent trains are virtually grouped into groups through the self-organizing network technology between vehicles 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, that is, the target group information to which the current train belongs. In an embodiment of the present invention, trains in the same group can be regarded as one train, thereby effectively improving the efficiency of receiving and dispatching trains and the operation density of existing lines.

[0047] Specifically, the group control center module of each current train performs train marshaling 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 marshaling result corresponding to each current train. The group control center module of each current train sends the train marshaling 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 grouping 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 by using a 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] Among them, the preset verification method may refer to a verification method that is preset to determine whether the current train is suitable for marshaling within a preset time period. For example, the preset verification method may be, but is not limited to, the driver manually judging whether the current train is suitable for marshaling or judging whether the current train is suitable for marshaling based on the current running state of the train. The verification result may include the current train allowing marshaling and the current train refusing marshaling. The verification result has a veto power. The train marshaling success result may refer to the current train marshaling success. An ordinary train may refer to a train that does not participate in marshaling, that is, a separate train.

[0050] Specifically, through the group control center module of the current train, the current train is checked for marshaling based on a preset verification method. If it is verified that the current train can be marshaled according to the target group information in the route sequence, the verification 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 verification result corresponding to the current train is determined as the current train refuses to be marshaled. Through the group control center module of the current train, if the verification 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 verification result of the current train is that the current train refuses to be marshaled, it is refused to be incorporated and the current train is determined as an ordinary train, and a train marshaling failure result is generated.

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

[0052] Among them, track similarity may refer to the similarity between tracks where 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 may be used to reflect whether the train triggers the route successfully. 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 can be entered, and the current occupation state of the sub-route. For example, when the state of the sub-route is that the signal device is locked, the sub-route can be entered, and the sub-route is not occupied, the train triggers the route successfully 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 corresponding 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 state adjustment strategy to the computer interlocking module and the group control center module. The state 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 the group train based on the received train formation results and route sequence through the dispatching 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 dispatching centralized control module, and determining the track similarity between adjacent trains in the group train based on the route sequence.

[0055] Specifically, the centralized dispatching 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 trigger in the target station based on the received status adjustment strategy to determine the sub-route trigger result, and sends the sub-route trigger 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, signal machines, and the safety interlocking relationship between switches, signal machines, and track circuits in the constrained route. In an embodiment of the present invention, the computer interlocking module can be used to adjust the state of the sub-route. The control range of a computer interlocking module is a 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. When 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. 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.

[0058] Specifically, the current sub-route is triggered for trains at different positions in the group trains through the computer interlocking module based on the state adjustment strategy. For example, for the first train in the group train, when the first train triggers the route, the tracks corresponding to all target trains in the group train are also triggered. , so as to determine the sub-route triggering result corresponding to each group train, and send the sub-route triggering result 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 target train is controlled to enter the current sub-route that has been successfully triggered. The group control center module unblocks the sub-route when the tail car in the group train leaves the current sub-route based on the received state adjustment strategy, that is, the current sub-route is adjusted from a blocked state to an unblocked state, thereby improving the route trigger success rate of the next train (other group trains or ordinary trains).

[0062] The technical solution of the embodiment of the present invention is to obtain the operation plans of multiple current trains through the dispatching centralized control module, 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 marshaling on multiple current trains based on the received route sequence to determine the train marshaling result, and send the train marshaling result to the dispatching centralized control module; the dispatching centralized control module determines the track similarity between adjacent trains in the group train based on the received train marshaling 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 computer The interlocking module controls the current sub-route trigger in the target station based on the received state adjustment strategy to determine the sub-route trigger result, thereby realizing unified route triggering for the group trains, avoiding repeated route triggering for 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 states 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 approach sequence of the ordinary train through the dispatching centralized control module, and the state adjustment strategy is sent to the computer interlocking module; the signal corresponding to the main approach of the ordinary train is controlled by the computer interlocking module based on the received state adjustment strategy, and the main approach state is adjusted to a closed state before the ordinary train enters the main approach, and the main approach state is adjusted 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 invisible 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 main approach is triggered for a complete approach corresponding to an ordinary train, i.e., the main approach, through the dispatching centralized control module, so as to generate a state adjustment strategy for the main approach corresponding to the ordinary train, and send the state adjustment strategy to the computer interlocking module. The state adjustment strategy for the main approach can be that when the main approach corresponding to the ordinary train is triggered, the main approach needs to be taken as a whole, and the state of the main approach, i.e., the trigger result, is displayed using the signal in front of the main approach. The signal corresponding to the main approach of the ordinary train is controlled by the computer interlocking module based on the received state adjustment strategy, and the state of the main approach is adjusted to a closed state before the ordinary train enters the main approach, and the state of the main approach is adjusted to an unblocked state when the ordinary train exits the main approach.

[0067] Figure 2 This is a flow chart of a group train route triggering method provided in the second embodiment of the present invention. Based on the above embodiment, this embodiment describes in detail the process of determining the state adjustment strategy. 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:

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

[0072] The advantage of this arrangement is that 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 can just keep the route trigger state of the preceding train, thereby improving the efficiency of the route triggering of the group trains. In addition, if the routes of all target trains in the group train are the same, no matter how many target trains there are in the group train, only one route trigger of the first train is required.

[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 dispatching centralized control module, and a second adjustment strategy is generated.

[0074] The closed state is a state where other group trains and ordinary trains cannot enter. The closed state is released by the group control center module. There is a corresponding group control center module on each current train. The advantage of this setting is that the closed state can prevent other group trains or ordinary trains from cutting in when a group train enters or leaves a station, causing congestion or collision, further improving the operation efficiency of the group train.

[0075] S260. If the following train is the last train in the group train, the sub-route state when the following train 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 unblocking state may refer to a state in which other group trains and ordinary trains can enter. The advantage of such a setting is that when all group trains leave the sub-route, the blocking state of the sub-route can be automatically released, so that other group trains or ordinary trains can effectively trigger the sub-route, avoiding data transmission back to the dispatching centralized control module and then issuing a release command through the dispatching centralized control module, thereby improving the overall operation efficiency of the current train.

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

[0078] Among them, when the track of the previous train is different from the track 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 triggering of repeated sub-routes 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. Control the current sub-route trigger in the target station through the computer interlocking module based on the received status adjustment strategy to determine the sub-route trigger result, and send the sub-route trigger 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 previous train in the adjacent train is the same as the track of the next train, the sub-route state of the next train before entering 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; so that when the routes of the previous train and the next train are exactly the same, only the previous train needs to trigger the route, and the next train does not need to trigger the route, and the route trigger state of the previous train can be maintained, thereby improving the efficiency of the group train route trigger. Moreover, if the routes of all target trains in the group train are the same, no matter how many target trains there are in the group train, only one first train route trigger is required. If the previous train is the first train in the group train, the sub-route state of the previous train before entering the sub-route is adjusted to a closed state through the scheduling centralized control module, and a second adjustment strategy is generated; so that the closed state can be used to avoid congestion or collision caused by other group trains or ordinary trains when a group train enters or leaves a station, further improving the operation efficiency of the group train. If the latter train is the last train in the group train, the sub-route state of the latter train when it leaves the sub-route is adjusted to the unblocked state through the dispatching centralized control module, and a third adjustment strategy is generated; thereby, other group trains or ordinary trains can effectively trigger the sub-route, avoiding the transmission of data back to the dispatching centralized control module and then issuing the release command through the dispatching centralized control module, thereby improving the overall operation efficiency of the current train. If the track of the previous train in the adjacent train is different from the track of the next train, the track state of the previous train when it leaves the track is adjusted to the unblocked state, and a fourth adjustment strategy is generated; thereby, when the track of the previous train is different from the track of the next train, only the state of the sub-route is adjusted for different sub-route, and there is no need to repeatedly trigger the same sub-route, thereby reducing the number of repeated sub-route triggering times in the group train, and further improving the group train route triggering efficiency. The dispatching centralized control module determines the state adjustment strategy corresponding to the sub-route of 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 out virtual signals, S, SII and SI can send out 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 first train route, and triggering a group following train route.

[0084] Among them, processing the train operation plan includes: the group train route trigger system receives the train operation plan issued by the dispatching desk and generates a route sequence according to the plan. The route sequence is fed back to the CTC control and display interface for display, and the display content includes the list of virtual signal sub-routes included in the receiving and dispatching routes and the group information 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 triggering system determines that the train is not a group train based on the train formation results, the route S-XI is triggered, 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 includes: when the group train route triggering system determines that the train is the group's first train according to the planned train formation results, it triggers the virtual signal sub-routes in sequence according to the order of near and far sub-routes and the rule of triggering a sub-route when a trigger condition is met. After the triggering is completed, the route is in the closed state of "triggering completed". Among them, signals S, LS1, and LS2 are all open 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 each sub-route that meets the conditions one by one 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 the group follower vehicle route includes: after the first vehicle in the group passes through the virtual signal route, the sub-route sequence automatically flows to the "clear" state, and at the same time, the corresponding sub-route sequence of the next train in the group is set to the "trigger completed" state, that is, the route of the next train is consistent with the previous vehicle, and there is no need to trigger it again, and it directly inherits the route of the previous vehicle. After all the sub-routes included in the route sequence of the previous vehicle are cleared, the route sequence is automatically deleted.

[0089] Group trains allow the following train (rear train) to have a different track from the first train (front train). If the track of the following train is different from that of the front train, after the front train passes, the group control center module will automatically unlock the virtual signal sub-route that is different from the path of the rear train, and it will be in the "waiting for trigger" state after unlocking. The virtual signal sub-route with the same path still maintains the "trigger completed" state of signal open. When the system determines that the route of the front train cannot be inherited, the sub-route of the rear train is automatically triggered. After triggering, it forms a complete entry and exit route together with the inherited sub-route. For example, the front train is the IG train route S-XI, and the rear train is the IIG train route S-XII. The first two sub-routes of the two routes are S-LS1 and LS1-LS2, while the third sub-route is different. After the front train passes, the LS2-XI route is unlocked, and the rear train needs to trigger the LS2-XII sub-route separately. The route sequence of the group's tail car is unlocked and automatically deleted as the train passes.

[0090] The following is an embodiment of the group train route triggering system provided in an embodiment of the present invention. The system and the group train route triggering methods of the above-mentioned embodiments belong to the same inventive concept. For details not described in detail in the embodiment of the group train route triggering system, reference can be made to the embodiment of the above-mentioned group train route triggering method.

[0098] On the basis of the above technical solution, the dispatching centralized control module 410 is also used to determine the group trains belonging to the same group based on the train grouping result and the route sequence if the train grouping result is a successful train grouping result, and to determine the track similarity between adjacent trains in the group train based on the route sequence.

[0099] On the basis of the above technical solution, the centralized dispatching control module 410 is also used to control the sub-route state of the subsequent train before entering the sub-route to be consistent with the sub-route state before the previous train enters the sub-route if the track of the previous train in the adjacent trains is the same as the track of the subsequent train, and generate a first adjustment strategy; the centralized dispatching control module 410 is also used to adjust the sub-route state of the previous train before entering the sub-route to a closed state if the previous train is the first train in the group of trains, and generate a second adjustment strategy; the centralized dispatching control module 410 is also used to control the sub-route state of the previous train before entering the sub-route to a closed state if the previous train is the first train in the group of trains.
