Description

Technical Field

[0001] This invention relates to the field of rail transit technology, specifically to a train operation control method and system. Background Technology

[0002] Currently, during fully automated, unmanned train operation, the central ATS (Automatic Train Protection System) must remain operational and in communication mode at all times. If the central ATS malfunctions, fully automated operation will cease, the train will stop at the platform or be unable to enter the station, potentially leading to serious operational accidents. Summary of the Invention

[0003] This invention provides a train operation control method and system that can solve problems such as the inability of trains to continue fully automatic operation due to malfunctions of the central ATS in the prior art.

[0004] A train operation control method, comprising:

[0005] The first control command is generated based on the train operation plan currently stored in the application module of the central ATS, and then sent to a preset communication device associated with the central ATS through the communication module of the central ATS, so that the preset communication device controls the train to run according to the train operation plan based on the first control command.

[0006] When a preset type of fault occurs in the central ATS, the preset communication device executes the operation control strategy corresponding to the preset type of fault to replace the train operation plan and continue to control the fully automatic operation of the train.

[0007] A train operation control method, applied to a pre-set communication device, includes:

[0008] The system receives a first control command sent by the communication module of the ATS (Automatic Train Protection System) and controls the train to operate according to the train operation plan based on the first control command.

[0009] When a preset type of fault occurs in the central ATS, the operation control strategy corresponding to the preset type of fault is executed to replace the train operation plan and continue to control the fully automatic operation of the train.

[0010] A train operation control method, applied to a central ATS, includes:

[0011] The first control command is generated based on the train operation plan currently stored in the application module of the central ATS, and then sent to a preset communication device associated with the central ATS through the communication module of the central ATS, so that the preset communication device controls the train to run according to the train operation plan based on the first control command.

[0012] When a preset type of fault occurs in the central ATS and the communication module does not experience a communication fault, the communication module sends a fault indication message to the station ATS, so that the station ATS notifies the preset communication equipment to execute the operation control strategy corresponding to the preset type of fault, thereby replacing the train operation plan to continue controlling the fully automatic operation of the train.

[0013] A train operation control method, applied to a station ATS, includes:

[0014] The fault indication information is sent by the communication module of the receiving center ATS. The fault indication information is sent by the center ATS when a preset type of fault occurs and the communication module does not experience a communication failure.

[0015] A control command is sent to a preset communication device so that the preset communication device executes an operation control strategy corresponding to the preset type of fault according to the control command, so as to replace the train operation plan and continue to control the train to operate in full automation.

[0016] A train operation control system includes a central ATS, station ATSs, and pre-set communication equipment; the central ATS includes an application module, a human-machine interaction module connected to the application module, and a communication module connected to the application module; the station ATS and the pre-set communication equipment are communicatively connected to the central ATS via the communication module; the train operation control system is used to execute the above-described train operation control method.

[0017] In this embodiment of the invention, before a preset type of fault is determined to have occurred in the central ATS, the central ATS generates a first control command based on the train operation plan currently stored in the application module, and then sends the first control command to a preset communication device through the central ATS's communication module to instruct the train to operate according to the train operation plan; after a preset type of fault is determined to have occurred in the central ATS, an operation control strategy corresponding to the preset type of fault is determined, and then the fully automatic operation of the train is continued by executing the operation control strategy. In this invention, the train can achieve fully automatic operation in the event of a central ATS fault, avoiding the risk of downtime. Attached Figure Description

[0018] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments of the present invention will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] Figure 1 This is a flowchart of a train operation control method according to an embodiment of the present invention.

[0020] Figure 2 This is a schematic diagram of the module structure of a train operation control system according to an embodiment of the present invention. Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In one embodiment, such as Figure 1 and Figure 2 As shown, the train operation control method includes the following steps S10-S20:

[0023] S10. Generate a first control command based on the train operation plan currently stored in the application module 111 of the central ATS11, and send the first control command to a preset communication device 13 associated with the central ATS11 through the communication module 113 of the central ATS11, so that the preset communication device 13 controls the train to operate according to the train operation plan based on the first control command; specifically, as follows... Figure 2As shown, the train operation control system 1 (used to execute the train operation control method of the present invention) includes a central ATS 11, a station ATS 12, and a preset communication device 13; the preset communication device 13 includes, but is not limited to, CI (Computer Interlocking), the train's VOBC (Vehicle On-Board Controller), and ZC (Zone Control Center). The central ATS11 includes, but is not limited to, an application module 111 (which includes an application server, a data server, etc.; the application server can perform logical processing to generate first control commands, etc.; the data server can be used to store train operation plans and related information, etc.), a human-machine interaction module 112 connected to the application module 111 (the human-machine interaction module 112 may include a human-machine interaction touch device, etc.; the central dispatcher can input second plan editing information through the human-machine interaction touch device to edit and modify the train operation plan), and a communication module 113 connected to the application module 111 (the communication module 113 includes an interface server, etc.; the central ATS11 communicates with the station ATS12 and other devices such as the preset communication device 13 through the interface server). The station ATS12 and the preset communication device 13 communicate with the central ATS11 through the communication module 113. Understandably, in this invention, the station ATS12 needs to establish a communication connection with the central ATS11's communication module 113 through a secure network to securely exchange plan information, etc.

[0024] In this embodiment, when all the modules of the central ATS11 are operating normally without any malfunctions, the application module 111 can generate a first control command based on its currently stored train operation plan. Then, it sends the first control command to the preset communication devices 13 associated with the central ATS11 via the communication module 113. This allows each preset communication device 13 to control the train to operate according to the train operation plan. The first control command includes control commands for different purposes set for different preset communication devices 13. For example, VOBC can control train movement according to the first control command; CI can process train routes and operate trackside equipment (such as switches and signals) related to the routes according to the first control command; ZC can process train movement authorization according to the first control command.

[0025] S20. When a preset type of fault occurs in the central ATS11, the preset communication device executes the operation control strategy corresponding to the preset type of fault to replace the train operation plan and continue to control the fully automatic operation of the train. Further, the preset type of fault includes, but is not limited to, a human-machine interaction fault in the human-machine interaction module 112 of the central ATS11, a logic or storage fault in the application module 111, and a communication fault in the communication module 113; wherein, a human-machine interaction fault refers to a fault in the human-machine interaction module 112, preventing the central dispatcher from editing the train operation plan by inputting second plan editing information through the human-machine interaction module 112; a logic or storage fault refers to a logic or storage fault in the application module 111, resulting in the inability to perform logic processing to generate control commands, and the inability to store the train operation plan and its related information; a communication fault refers to a fault in the communication module 113, preventing the central ATS11 from communicating with the station ATS12 and other devices such as the preset communication device 13 through the communication module 113. Understandably, all of the above-mentioned preset fault types may cause the central ATS11 to malfunction in the fully automated train operation scenario. Therefore, in this invention, different operation control strategies can be adopted to maintain fully automated train operation for the above-mentioned preset fault types.

[0026] In the above embodiments of the present invention, before a preset type of fault is determined to have occurred in the central ATS11, the central ATS11 generates a first control command based on the train operation plan currently stored in the application module 111, and then sends the first control command to the preset communication device 13 through the communication module 113 of the central ATS11 to instruct the train to operate according to the train operation plan; after a preset type of fault is determined to have occurred in the central ATS11, an operation control strategy corresponding to the preset type of fault is determined, and then the fully automatic operation of the train is continued by executing the operation control strategy. In the present invention, the train can continue to operate fully automatically in the event of a fault in the central ATS11 without the need to add backup central equipment, avoiding the risk of downtime, and without the need for excessive intervention by dispatchers, further reducing labor costs, conforming to the ultimate unmanned operation concept of fully automatic operation, improving the fault tolerance and availability of the central ATS11, and reducing the pressure on maintenance caused by equipment failure.

[0027] In one embodiment, the preset type of fault includes a human-machine interaction fault of the human-machine interaction module 112 of the central ATS11; in step S20, before the preset communication device executes the operation control strategy corresponding to the preset type of fault, the following steps are included:

[0028] The central ATS determines whether the application module 111 has received a heartbeat packet sent by the human-computer interaction module 112 within a first time interval before the current time point; wherein, the first time interval can be set according to requirements, such as 5 seconds; in this embodiment, the human-computer interaction module 112 sends heartbeat packets to the application module 111 at regular intervals, so as to determine whether the application module 111 periodically receives heartbeat packets to determine whether the human-computer interaction module 112 is currently experiencing a human-computer interaction failure.

[0029] If no heartbeat packet is received from the human-machine interaction module 112 within the first time interval, it is determined that the human-machine interaction module 112 has experienced a human-machine interaction failure. That is, if the application module 111 does not receive a heartbeat packet from the human-machine interaction module 112 within the first time interval before the current time point, and the application module 111 itself is operating normally (without any logic or storage failure), it indicates that the human-machine interaction module 112 has experienced a human-machine interaction failure. At this time, the central dispatcher will not be able to edit the train operation plan by entering the second plan editing information through the human-machine interaction module 112 (or perform any other operations through the human-machine interaction module 112). Therefore, the application module 111 needs to continue to execute the train operation plan already stored in the application module 111, and the train operation plan currently stored in the application module 111 cannot be modified by entering the second plan editing information through the human-machine interaction module 112.

[0030] If a heartbeat packet is received from the human-machine interaction module 112 within the first time interval, it is determined that the human-machine interaction module 112 has not experienced a human-machine interaction failure. Understandably, if the application module 111 receives a heartbeat packet from the human-machine interaction module 112 within the first time interval before the current time point, it indicates that the human-machine interaction module 112 is operating normally; therefore, the human-machine interaction module 112 has not experienced a human-machine interaction failure. The application module 111 currently needs to continue executing the train operation plan stored in the application module 111, but the train operation plan currently stored in the application module 111 can be modified by entering second plan editing information through the human-machine interaction module 112.

[0031] In one embodiment, the preset type of fault includes a human-machine interaction fault of the human-machine interaction module 112 of the central ATS11, a logic or storage fault of the application module 111, and a communication fault of the communication module 113; further, step S20, that is, when a preset type of fault occurs in the central ATS11, the preset communication device executes an operation control strategy corresponding to the preset type of fault, including:

[0032] When a human-computer interaction failure occurs in the human-computer interaction module 112, if the application module 111 does not experience a logical or storage failure and the communication module 113 does not experience a communication failure, the preset communication device executes the first operation strategy corresponding to the human-computer interaction failure. That is, the first operation strategy requires the assistance of the communication module 113 and the application module 111 for execution. Therefore, when a human-computer interaction failure is determined to occur in the human-computer interaction module 112, the first operation strategy can only be executed if the application module 111 does not experience a logical or storage failure and the communication module 113 does not experience a communication failure. Specifically, the first operation strategy includes:

[0033] The central ATS determines whether the communication module 113 has received the station update plan sent by the station ATS 12. The station update plan refers to the operation plan obtained after updating the train operation plan currently stored in the station ATS 12 according to the first plan editing information entered by the station operator of the station ATS 12. That is, in this invention, after each time the central ATS 11 formulates or updates the train operation plan, it will synchronously send the latest train operation plan to the station ATS 12 associated with the central ATS 11, so that the station ATS 12 also has the latest train operation plan. Therefore, in this embodiment, if the human-machine interaction module 112 experiences a human-machine interaction failure, the application module 111 should first be instructed to continue executing the train operation plan stored in the application module 111. At this time, since the train operation plan currently stored in application module 111 cannot be modified by entering the second plan editing information through human-machine interaction module 112, if it is necessary to modify the train operation plan, the dispatcher of the central ATS11 can contact the station operator of the station ATS12 by telephone (or other means), so that the station operator of the station ATS12 can enter the first plan editing information according to the instructions through the human-machine interaction device of the station ATA. Then, the station ATS12 can update the train operation plan currently stored in the station ATS12 according to the first plan editing information to obtain the station updated plan. Furthermore, the station ATS12 will synchronously upload the station updated plan to the application module 111 of the central ATS11 through communication module 113, so that the application module 111 can synchronously update the train operation plan currently stored in the application module 111 according to the station updated plan. Therefore, in the first operating strategy, the train operation plan stored in the application module 111 is first executed (that is, a first control command is generated according to the train operation plan currently stored in the application module 111 of the central ATS11, and the first control command is sent to the preset communication device 13 associated with the central ATS11 through the communication module 113 of the central ATS11, so that the preset communication device 13 controls the train to run according to the train operation plan according to the first control command), while determining whether the communication module 113 has received the station update plan sent by the station ATS12.

[0034] After the communication module 113 receives the station update plan sent by the station ATS 12, it replaces the train operation plan currently stored in the application module 111 with the station update plan. That is, when the application module 111 receives the station update plan sent by the station ATS 12 through the communication module 113, it needs to synchronously update the train operation plan currently stored in the application module 111 according to the station update plan; that is, it replaces the train operation plan currently stored in the application module 111 with the station update plan. In this embodiment, when the human-machine interaction module 112 of the central ATS 11 experiences a human-machine interaction failure, the train operation plan can be edited and modified through the human-machine interaction device of the station ATS 12. After obtaining the station update plan, it is saved in the station ATS 12 and synchronously uploaded to the central ATS 11 for storage and execution by the central ATS 11.

[0035] The application module 111 generates a second control command based on the replaced station update plan, and sends the second control command to a preset communication device 13 associated with the central ATS 11 via the communication module 113, so that the preset communication device 13 controls the train to operate according to the replaced train operation plan based on the second control command. In other words, after the station update plan uploaded by station ATS12 replaces the original train operation plan stored in application module 111, application module 111 will execute the latest station update plan stored in application module 111. In this way, even after a human-machine interaction failure occurs, the central ATS11 can still add, adjust, delete, and execute station operation plans normally to continue controlling the fully automatic operation of trains and ensure that trains operating normally are not affected. Understandably, after the maintenance personnel repair the above-mentioned human-machine interaction failure, they can still determine whether the human-machine interaction failure has been resolved by whether a heartbeat packet has been received, or the maintenance personnel can directly notify application module 111 that the human-machine interaction failure has been resolved through information commands, so that the human-machine interaction module 112 of the central ATS11 can resume normal use, that is, continue to edit and modify the station operation plan by entering the second plan editing information through the human-machine interaction module 112 of the central ATS11.

[0036] In one embodiment, the preset type of fault includes a human-machine interaction fault of the human-machine interaction module 112 of the central ATS11, a logic or storage fault of the application module 111, and a communication fault of the communication module 113; further, in step S10, after sending the first control command through the communication module 113 of the central ATS11 to the preset communication device 13 associated with the central ATS11, the method further includes:

[0037] When the human-machine interaction module 112 does not experience a human-machine interaction failure, if the application module 111 does not experience a logical or storage failure and the communication module 113 does not experience a communication failure, then it is determined whether the human-machine interaction module 112 has received the second plan editing information entered by the central dispatcher of the central ATS 11. That is, when it is determined that the human-machine interaction module 112, the application module 111, and the communication module 113 are all functioning correctly, the application module 111 needs to continue executing the train operation plan stored in the application module 111. The train operation plan currently stored in the application module 111 can be modified by entering the second plan editing information through the human-machine interaction module 112. Therefore, it is necessary to determine whether the human-machine interaction module 112 has received the second plan editing information entered by the central dispatcher of the central ATS 11.

[0038] After receiving the input second plan editing information, the application module 111 updates the train operation plan currently stored in the application module 111 according to the input second plan editing information, and sends the updated train operation plan synchronously to the station ATS12 associated with the central ATS11 through the communication module 113; that is, after the central dispatcher inputs the second plan editing information through the human-computer interaction module 112, the application module 111 updates the train operation plan currently stored in the application module 111 according to the input second plan editing information, and then synchronously updates the latest updated train operation plan to the station ATS12 in real time, so that when the human-computer interaction module 112 has a human-computer interaction failure, the same train operation plan stored in the application module 111 can be updated in a timely manner by editing the train operation plan in the station ATS12 and uploading it to the ATS.

[0039] The application module 111 generates a fifth control command based on the updated train operation plan and sends the fifth control command to a preset communication device 13 associated with the central ATS 11 via the communication module 113. The preset communication device 13 then controls the train to operate according to the updated train operation plan based on the fifth control command. In other words, after updating the original train operation plan stored in the application module 111, the application module 111 executes the updated station update plan stored in the application module 111. This allows the central ATS 11 to normally add, adjust, delete, and execute station operation plans, thus continuing to control the fully automated operation of the train.

[0040] In one embodiment, the preset type of fault includes a logical or storage fault of the application module 111 and a communication fault of the communication module 113; further, in step S20, before the preset communication device executes the operation control strategy corresponding to the preset type of fault, the following steps are included:

[0041] When the communication module 113 does not experience a communication failure, it is determined whether the station ATS12 has received the planning information sent by the application module 111 through the communication module 113 within a second time interval before the current time point. The planning information includes the train operation plan currently stored in the application module 111. The second time interval can be set according to requirements, such as 5 seconds. Understandably, the first time interval can be the same as or different from the second time interval. In this embodiment, the application module 111 periodically sends the planning information to the station ATS12 through the communication module 113. That is, the station ATS12 and the central ATS11 will establish periodic communication. The central ATS11 will periodically send the planning information containing the train operation plan in the application module 111 to the station ATS12 through a secure communication protocol. The station ATS12 will store a complete train operation plan that is consistent with the central ATS11. Thus, when the communication module 113 does not experience a communication failure, the station ATS12 can determine whether the application module 111 has experienced a logical or storage failure by checking whether it receives the planning information sent by the application module 111 through the communication module 113 within a second time interval before the current time point. Understandably, when the communication module 113 has not experienced a communication failure, the station ATS 12 determines whether it has received the planning information sent by the application module 111 through the communication module 113 within the second time interval before the current time point. Specifically, this includes: determining whether the station ATS 12 has received the communication information sent by the communication module 113 within the second time interval before the current time point; if the communication information is received, determining that the communication module 113 has not experienced a communication failure; and then determining whether the communication information contains data with a specific format corresponding to the train operation plan (the data corresponding to the train operation plan has a specific format). If the communication information contains data with a specific format corresponding to the train operation plan, it indicates that the station ATS 12 has received the planning information sent by the application module 111 through the communication module 113 within the second time interval before the current time point; if the communication information does not contain data with a specific format corresponding to the train operation plan, it indicates that the station ATS 12 has not received the planning information sent by the application module 111 through the communication module 113 within the second time interval before the current time point.

[0042] If the application module 111 does not receive the planned information sent by the application module 111 within the second time interval, it is determined that the application module 111 has experienced a logical or storage failure. That is, if the station ATS12 does not receive the planned information sent by the application module 111 through the communication module 113 within the second time interval before the current time point, since the communication module 113 is operating normally (the communication module 113 has not experienced a communication failure), it indicates that the application module 111 has experienced a logical or storage failure. At this time, the application module 111 cannot perform logical processing to generate control commands, nor can it store the train operation plan and related information.

[0043] If the planning information sent by the application module 111 is received within the second time interval, it is determined that the application module 111 has not experienced a logical or storage failure. That is, if the station ATS12 receives the planning information sent by the application module 111 through the communication module 113 within the second time interval before the current time point, both the communication module 113 and the application module 111 are operating normally. Therefore, it is determined that the application module 111 has not experienced a logical or storage failure. At this time, the application module 111 can perform logical processing to generate control commands, and can also store the train operation plan and related information.

[0044] In one embodiment, the preset type of fault includes a logical or storage fault in the application module 111 and a communication fault in the communication module 113; further, step S20, that is, when a preset type of fault occurs in the central ATS 11, the preset communication device executes an operation control strategy corresponding to the preset type of fault, including:

[0045] When a logical or storage failure occurs in application module 111, but no communication failure occurs in communication module 113, the preset communication device executes a second operating strategy corresponding to the logical or storage failure. That is, the second operating strategy requires the assistance of communication module 113 for execution. Therefore, when a logical or storage failure is determined in application module 111, the second operating strategy can only be executed if communication module 113 has not experienced a communication failure. Specifically, the second operating strategy includes:

[0046] The station ATS12 generates a third control command based on the currently stored train operation plan in the station ATS12, and sends the third control command to a preset communication device 13 associated with the central ATS11 via the communication module 113 of the central ATS11. The preset communication device 13 then controls the train to operate according to the train operation plan based on the third control command. That is, when the application module 111 of the central ATS11 experiences a logic or storage failure, the application module 111 cannot perform logic processing to generate control commands, nor can it store the train operation plan and related information. Therefore, at this time, it is necessary to use the station ATS12 to replace the faulty application module 111 to realize its logic processing and storage functions. Therefore, in this embodiment, in the second operation strategy, the station ATS12 is first instructed to generate a third control command based on the train operation plan currently stored in the station ATS12. Then, the third control command is transmitted to the communication module 113 in the central ATS11, which is still in normal working condition. The communication module 113 then sends the third control command to the preset communication device 13 associated with the central ATS11, so that the preset communication device 13 controls the train to run according to the train operation plan based on the third control command. That is, in this embodiment, the station ATS12 can partially replace the function of the central ATS11 (that is, the logic processing and storage function implemented by the faulty application module 111), thereby enabling the continued fully automatic operation of the train even when the application module 111 of the central ATS11 experiences a logic or storage failure.

[0047] Furthermore, after the third control command is sent by the communication module 113 of the central ATS11 to the preset communication device 13 associated with the central ATS11, the method further includes:

[0048] After the station ATS12 receives the first plan editing information entered by the station operator, it updates the currently stored train operation plan in the station ATS12 to obtain the station updated plan. That is, in this embodiment, due to a logical or storage failure in the application module 111 of the central ATS11, the human-computer interaction module 112 of the central ATS11 cannot be used either (the second plan editing information entered through the human-computer interaction module 112 still needs to be logically processed by the application module 111). Therefore, the train operation plan cannot be edited and modified by the application module 111 according to the second plan editing information. Therefore, in this embodiment, the above-mentioned function of editing and modifying the train operation plan is implemented by the station ATS12. Specifically, if it is necessary to modify the train operation plan, the dispatcher of the central ATS11 can contact the station operator of the station ATS12 by telephone (or other means). The station operator of the station ATS12 can then enter the first plan editing information according to the instructions through the human-computer interaction device of the station ATA. Then, the station ATS12 can update the train operation plan currently stored in the station ATS12 according to the above-mentioned first plan editing information to obtain the station updated plan.

[0049] The station ATS12 is instructed to generate a fourth control command based on the station update plan, and send the fourth control command to a preset communication device 13 associated with the central ATS11 through the communication module 113 of the central ATS11, so that the preset communication device 13 controls the train to operate according to the train operation plan based on the fourth control command. In this embodiment, due to a logic processing and storage failure in the application module 111, even if the station ATS12 uploads the station update plan to the communication module 113 of the central ATS11, the application module 111 still cannot process it. Therefore, in this embodiment, the station ATS12 directly generates a fourth control command based on the station update plan, and then sends the fourth control command to the communication module 113 of the central ATS11. The communication module 113 then sends the fourth control command to the preset communication device 13 associated with the central ATS11, so that the preset communication device 13 controls the train to run according to the train operation plan based on the fourth control command. In this way, even if the application module 111 fails, the central ATS11 can still add, adjust, delete, and execute the station operation plan normally, so as to continue to control the fully automatic operation of the train and ensure that the normal operation of the line is not affected. Understandably, after the maintenance personnel have repaired the logic processing and storage faults of the application module 111, they can still determine whether the logic processing and storage faults of the application module 111 have been resolved by checking whether the station ATS12 has received the planning information sent by the application module 111. Alternatively, the maintenance personnel can directly notify the application module 111 that the logic processing and storage faults have been resolved through information commands, thereby enabling the application module 111 of the central ATS11 to resume normal use.

[0050] In one embodiment, the preset type of fault includes a communication fault of the communication module 113; further, in step S20, before the preset communication device executes the operation control strategy corresponding to the preset type of fault, the following steps are included:

[0051] The preset communication device 13 determines whether it has received communication information sent by the communication module 113 within a third time interval before the current time point; wherein, the third time interval can be set according to requirements, such as 5 seconds. Understandably, the third time interval can be the same as or different from the second time interval or the first time interval. In this embodiment, when the communication module 113 is operating normally, the central ATS 11 or the station ATS 12 will continuously send communication information to each preset communication device 13 through the communication module 113 at regular intervals. The communication information can refer to the first control command, the second control command, the fifth control command, etc. mentioned above, or it can refer to the heartbeat packets sent by the communication module 113 to the preset communication device 13 at regular intervals.

[0052] If no communication information is received from the communication module 113 within the third time interval, it is determined that the communication module 113 has a communication failure; that is, if no communication information is received from the communication module 113 within the third time interval, it indicates that the communication module 113 has a communication failure. At this time, the central ATS 11 cannot communicate with the station ATS 12 and other devices such as the preset communication device 13 through the communication module 113.

[0053] If communication information is received from the communication module 113 within the third time interval, it is determined that the communication module 113 has not experienced a communication failure. That is, if communication information is received from the communication module 113 within the third time interval, it indicates that the communication module 113 has not experienced a communication failure. In this case, the central ATS 11 can continue to communicate with the station ATS 12 and other devices such as the preset communication device 13 through the communication module 113.

[0054] In one embodiment, before sending the first control command to the preset communication device 13 associated with the central ATS11 via the communication module 113 of the central ATS11 in step S10, the method includes: storing the path configuration information associated with the preset communication device 13 in the preset communication device 13, and then switching the preset communication device 13 to the online working state. That is, in this embodiment, each preset communication device 13 in the train operation line corresponding to the central ATS11 is configured with corresponding path configuration information, and the configured path configuration information will be associated and stored in the preset communication device 13 corresponding to it; when the preset communication device 13 is the VOBC of the train, the path configuration information corresponding to the VOBC includes degraded operation information, which includes, but is not limited to, the most frequently operated train operation path (the most frequently operated train operation path is selected based on operational demand characteristics such as the largest passenger flow, passing through important areas, the most transfer stations, and the longest total route length), and the corresponding route information and destination information (the destination can be a platform, turnaround track, or conversion track, etc.) on the train operation path. When a communication failure occurs in communication module 113, the train's VOBC needs to control the train to operate according to the aforementioned train degradation information. When the preset communication device 13 is CI, the path configuration information includes standard route information stored in the CI. The CI can determine different trigger segments based on this standard route information. Then, after detecting that any of the trigger segments is occupied by a train, the CI controls the execution of the standard route operation corresponding to the trigger segment. When the preset communication device 13 is ZC, the path configuration information may include movement authorization operation data. Therefore, after a communication failure occurs in communication module 113, the ZC can execute the train's movement authorization operation based on the aforementioned movement authorization operation data. Understandably, the aforementioned path configuration information needs to be configured and stored in the corresponding preset communication device 13 before the train operation control system 1 starts operating. Then, when the train operation control system 1 starts operating, the preset communication device 13 switches to the online working state (it cannot be entered through the human-machine interface after the train operation control system 1 starts operating). In this way, it can avoid the failure of entry due to the communication network abnormality of a certain module, thereby ensuring the normal and continuous operation of the entire train operation control system 1 to the greatest extent.

[0055] In one embodiment, the preset type of fault includes a communication fault of the communication module 113; the preset communication device 13 includes CI, ZC, and the train's VOBC; the path configuration information includes standard route information stored in the CI; specifically, step S20, that is, when a preset type of fault occurs in the central ATS11, the preset communication device executes the operation control strategy corresponding to the preset type of fault, including:

[0056] When a communication failure occurs in the communication module 113, the preset communication device 13 executes a third operating strategy corresponding to the communication failure. That is, when a communication failure occurs in the communication module 113, the human-computer interaction module 112 and the application module 111 cannot function regardless of whether a human-computer interaction failure has occurred. Therefore, it is not necessary to determine whether the human-computer interaction module 112 and the application module 111 have failed before executing the third operating strategy. The third operating strategy includes:

[0057] If it is determined that the CI has executed all control commands received from the communication module 113, then standard route information is obtained from the path configuration information stored in the CI, and a trigger segment is determined based on the standard route information; that is, in this embodiment, the communication module 113 periodically sends communication information to the CI. The communication information can be a route processing command issued by the central ATS 11 or the station ATS 12 to the CI through the communication module 113 (this route processing command is included in the control commands). Therefore, once the communication module 113 of the central ATS 11 experiences a communication failure, the CI will... If no more route processing commands can be received from the central ATS11 or the station ATS12, the third operating strategy is executed. That is, all control commands currently received from the communication module 113 (such as the first control command, the second control command, the fifth control command, etc.) are executed first. After all the issued control commands are executed, the CI will automatically switch to the standard route mode, and then obtain the standard route information in the path configuration information stored in the CI in advance. Then, the triggering section is determined according to the above standard route information. There is a chain automatic triggering relationship between each departure section.

[0058] Upon detecting that any of the trigger sections is occupied by a train, the CI is controlled to trigger the execution of the standard route operation corresponding to the trigger section, sending a standard route prompt to the train's VOBC and notifying the ZC to execute the train's movement authorization operation. That is, after determining that the train's departure section is occupied, it indicates that the train is approaching the route corresponding to the standard route information. Therefore, the CI needs to be controlled to trigger the execution of the standard route operation corresponding to the trigger section, i.e., automatically checking conditions and processing and opening the route for the train, operating the route-related trackside equipment (turnouts, signals, etc.), and thus preparing for the ZC to calculate the movement authorization. Simultaneously, after the standard route operation successfully opens the route, the ZC should be notified to execute the train's movement authorization operation so that the ZC can normally calculate the train's movement authorization. At the same time, the CI should send a "already on a standard route" prompt to the VOBC, so that the VOBC, upon receiving the standard route prompt, controls the train to proceed according to the downgraded operation information. In this embodiment, the third operation strategy described above can achieve automatic standard route operation and train movement authorization operation by CI without the participation of the central ATS11, ensuring continuous fully automatic operation of the train.

[0059] In one embodiment, the route configuration information further includes degraded operation information stored in the train's VOBC; further, the third operating strategy also includes:

[0060] The degraded operation information is obtained from the path configuration information stored in the VOBC of the train that has received the standard route prompt. That is, in this embodiment, the communication module 113 periodically sends communication information to the VOBC. The communication information can be the plan information containing the train operation plan sent to the VOBC by the central ATS11 or the station ATS12 through the communication module 113. Therefore, once the communication module 113 of the central ATS11 fails, the VOBC will no longer be able to receive the plan information from the central ATS11 or the station ATS12. At this time, the VOBC will detect in real time whether it has received the standard route prompt sent by the CI. Understandably, the path configuration information corresponding to the VOBC includes degraded operation information, which includes, but is not limited to, the most frequently operated train operation path (the most frequently operated train operation path is selected based on the operational demand characteristics such as the largest passenger flow, passing through important areas, the most transfer stations, and the longest total route length), as well as the corresponding route information and destination information (the destination can be a platform, turnaround track, or transfer track, etc.) on the train operation path.

[0061] After the VOBC determines the destination based on the downgraded operation information and the current direction of the train, it controls the train to travel according to the downgraded operation information. That is, when the communication module 113 experiences a communication failure, the VOBC receives a standard route prompt, then the VOBC enters the downgraded departure function. After obtaining the path configuration information stored in the VOBC, the VOBC automatically retrieves the downgraded operation information from the configured path configuration information. Based on the destination information contained in the downgraded operation information and the current direction of the train, it can determine the default destination (terminal station, turnaround track, etc.) of the corresponding configured train operation path in the path configuration information, and then determine the destination as the current destination of the train, thereby controlling the train to travel towards the destination according to the downgraded operation information.

[0062] If the communication fault of the communication module 113 persists before the train reaches its destination, the VOBC will control the train to stop upon arrival at the destination. That is, the train's stop time will be set to the default stop time and door opening / closing time included in the degraded operation information. After the stop time ends, the train will automatically depart based on the route information and movement authorization information in the degraded operation information, without skipping stops, skipping stations, or clearing passengers en route. If the communication fault of the communication module 113 persists before the train reaches its destination, the train will continue to run until it comes to a complete stop at the destination. If the destination is a turnaround track and the turnaround route has been successfully triggered, the VOBC should automatically complete the end change here and set a new destination based on the aforementioned degraded operation information and the train's new current direction of travel. Then, the VOBC will continue to control the train to travel towards the new destination according to the aforementioned degraded operation information.

[0063] Furthermore, after executing the third operating strategy corresponding to the communication failure, the method further includes: when the communication failure of the communication module 113 is resolved, instructing the preset communication device 13 to re-execute the train operation plan according to the control instructions sent by the communication module 113. That is, in this embodiment, once the preset communication devices 13 such as CI and VOBC detect that the communication module 113 of the centerline ATS has returned to normal (i.e., the communication failure is resolved), they can receive new control instructions sent by the center ATS 11 or the station ATS 12 through the communication module 113. Therefore, the preset communication device 13 will no longer execute the third operating strategy, but will automatically re-execute the train operation plan according to the control instructions sent by the communication module 113. For details, refer to the embodiments above where the communication module 113 has not experienced a communication failure, which will not be repeated here.

[0064] In the above embodiments of the present invention, when a communication failure occurs in the communication module 113, each train associated with the central ATS11 can still continue to run safely according to the route configuration information, minimizing the impact of various preset types of failures of the central ATS11 on operations, and also buying time for fault repair and recovery. Furthermore, the execution of the above-mentioned operational strategies of the present invention is automatically triggered under certain conditions, without requiring manual switching by dispatchers (therefore, there is no need to consider the impact of faults on switching operations), and does not increase the operational burden. Simultaneously, after maintenance personnel resolve the fault and restore normal operation of the central ATS11, dispatchers can directly intervene without additional exit operations, meeting the requirements of unmanned, high-performance operation in fault scenarios.

[0065] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0087] In one embodiment, the route configuration information further includes degraded operation information stored in the train's VOBC; the third operating strategy further includes:
