Description

Technical Field

[0001] This invention relates to the field of rail transit technology, specifically to a train control method and system for arrival / departure track branching off with red, blue, and white route signals. Background Technology

[0002] In the station design process of freight railways and overseas freight railways, special needs such as the use of dedicated tracks for parking railcars, maintenance trains, faulty vehicles, and locomotives with Automatic Train Protection (ATP) failures are taken into consideration. Therefore, in the station design, the middle of the side track receiving track is branched off to lead out a dedicated spare parking track. In order to meet the transportation organization efficiency of special operations, namely, that maintenance trains or faulty trains in the section can quickly enter the spare parking track from the section in one pass through the station receiving operation, the two ends of the track are equipped with departure signals that have both train and shunting functions.

[0003] On the other hand, unlike the traditional arrival and departure line branching design of railways, the protection of the middle turnout of this traditional track is provided by the shunting signal. When there is a need for operation to the side of the middle turnout on this track, it can only be carried out by shunting operation. It is not possible to connect the train in the section to the spare parking track in one go through train operation. Trains stored in the spare parking track cannot enter the section in one go through train operation. It can be seen that the traditional arrival and departure line branching design cannot meet the needs of train reception and departure operations on the spare parking track.

[0004] Meanwhile, some safety issues arise when combining the traditional arrival / departure track branching design with the requirements of this type of backup parking track for train arrival and departure operations. If the shunting signal passing through the protective track branching point opens the departure route signal from the backup parking track to the section in one go, because the shunting signals on both sides of the track branching point do not have train signal protection functions, if other trains are parked at the other end of the arrival / departure track branching point and see the departure signal open ahead, they may mistakenly believe that a departure operation is about to begin. When they pass the protective shunting signal of the track branching point, they may collide with a train departing from the backup parking track from the side of the track branching point, resulting in a side collision accident.

[0005] Therefore, to meet the needs of transportation organization and solve technical problems, special designs were made for the arrival / departure track branching and spare parking tracks at relevant freight railway stations. First, the shunting signals protecting both ends of the arrival / departure track branching were replaced with red-blue-white route signals that simultaneously function as both train and shunting signals. Blue lights indicate train permission, white lights indicate shunting permission, and red lights indicate both train and shunting prohibition, thus meeting the protection requirements of the arrival / departure track branching. Second, departure / shunting signals were installed at both ends of the spare parking tracks to meet the arrival / departure operation needs of these tracks.

[0006] Due to the special design of the red, blue, and white approach signals and the spare parking track on the arrival and departure lines, a large number of complex interlocking relationships that cannot be satisfied by existing systems are generated when combined with the station interlocking related functions. These include the design of arrival and departure track train reception and departure operations, the control logic of the red, blue, and white approach signals, the route management of the red, blue, and white approach signals, and the design of train reception and departure operations on the spare parking track. Summary of the Invention

[0007] The purpose of this invention is to provide a train control method and system for arrival / departure track branching off with red, blue, and white route signals, in order to solve the problems of traditional arrival / departure track branching off design facing operational requirements when receiving and dispatching trains on standby parking tracks and complex interlocking relationships that existing train computer interlocking systems cannot meet.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: On one hand, the present invention provides a train control method for arrival / departure track branching off with red, blue, and white route signals, which is used in freight railway stations with arrival / departure track branching off and spare parking tracks. The arrival / departure track branching off includes a branching turnout section, and red, blue, and white route signals are provided at both ends of the branching turnout section. The method includes: The red, blue, and white route signal controller can be controlled to achieve various light displays, with different light displays corresponding to different control signals; The system establishes the starting point of the established train route and the ending point of the train receiving route or guiding receiving route, and determines the control signals corresponding to the red, blue and white route signals. This enables the system to process train receiving routes or guiding receiving routes to the departure / arrival track or departure routes from the departure / arrival track in one go, as well as train receiving routes to the spare parking track or departure routes from the spare parking track in one go.

[0009] Preferably, the control signal controller for red, blue, and white routes enables multiple light displays, with different light displays corresponding to different control signals, specifically including: The red, blue, and white route signals are controlled by a fully electronic execution module in a computer interlocking system or a train control interlocking integrated control system to achieve three light displays: when the red, blue, and white route signal opens the train prohibition signal, the red light of the red, blue, and white route signal is lit; when a shunting route is initiated from the red, blue, and white route signal and the train permit signal is opened, the white light of the red, blue, and white route signal is lit; when a train route to the arrival / departure track or the spare parking track is initiated through the red, blue, and white route signal and the train permit signal is opened, the blue light of the red, blue, and white route signal is lit.

[0010] Preferably, each end of the arrival / departure track is provided with an entry signal and two exit signals corresponding to the two entry signals; The aforementioned setting establishes the starting point of the train route and the ending point of the train receiving route or guiding receiving route, and determines the control signals corresponding to the red, blue, and white route signals, enabling the one-time processing of train receiving routes or guiding receiving routes to the departure / arrival track or departure routes from the departure / arrival track, specifically including: On the operation display of the computer interlocking system or the integrated train control interlocking system, the control does not establish a separate train route starting from the red, blue and white signals; The endpoint of the train receiving route to the departure / arrival track is the exit signal blocking the same direction on the track, and the red, blue and white route signals are set to open the train permission signal, so as to process the train receiving route to the departure / arrival track in one go. The endpoint of the guiding train receiving route to the departure / arrival track is the red, blue, and white route signal that blocks the train in the same direction on the track, so as to process the guiding train receiving route to the departure / arrival track in one go. The departure signal is set as the departure route for the railway section between the departure signal and the adjacent station, and no departure route starting from the red, blue and white route signal is established, thereby realizing the one-time processing of the departure route from the arrival and departure line to the branch track.

[0011] Preferably, when processing the guiding route to the departure / arrival track, it is not necessary to confirm whether the red, blue, and white route signals have opened the train permission signal.

[0012] Preferably, the spare parking track is equipped with a departure signal; the establishment of the starting point of the established train route and the ending point of the established train receiving route, and the determination of the control signals corresponding to the red, blue, and white route signals, to realize the one-time processing of train receiving routes to the spare parking track or departure routes from the spare parking track, specifically includes: On the operation display of the computer interlocking system or the integrated train control interlocking system, the control does not separately establish a train route from the red, blue and white signal to the spare parking track; The endpoint of the train receiving route to the backup parking track is the exit signal blocking the station in the same direction on the backup parking track; and the red, blue and white route signals are set to open the train permission signal, thereby realizing the one-time processing of the departure route from the departure track of the arrival and departure line; The route from the spare parking track to the red-blue-white approach signal and the route from the red-blue-white approach signal to the railway section between the adjacent station are combined into a combined train route. The departure route from the spare parking track through the red-blue-white approach signal to the railway section is handled in one go through the combined train route.

[0013] Preferably, when processing a train receiving route to the backup parking track, the station entry signal is always illuminated; When processing departure routes from the designated backup parking lane, the departure signal is always illuminated.

[0014] Preferably, it further includes: a route starting from the station entry signal and blocked by the red-blue-white route signal is a short-running route, and a route starting from the red-blue-white route signal is a red-blue-white train route; different unlocking methods for the red-blue-white train route are set according to the unlocking status of the short-running route or whether the red-blue-white train route is blocked by a train, so as to unlock the red-blue-white train route.

[0015] Preferably, different unlocking methods are set for the red-blue-white train route based on its unlocking status or whether it is being blocked by another train, specifically including: When unlocking is performed by operating the total cancellation / total human release / area fault release method, if the short-connection train route is not unlocked, operating the total cancellation / total human release / area fault release on the human-machine interaction device of the computer interlocking system or the train control interlocking integrated control system is only used to close the signal and cannot unlock the red, blue and white train route. The red, blue and white train route is unlocked by operating the total cancellation / total human release / area fault release of the station entry signal. When unlocking via normal train operation, if the short-circuit train route is not unlocked, the red, blue, and white train route cannot be unlocked via normal train operation; if the short-circuit train route is unlocked, the red, blue, and white train route can be unlocked via normal train operation.

[0016] Preferably, different unlocking methods are set for the red-blue-white train route based on the unlocking status of the short-distance train route or whether the red-blue-white train route is blocked by a train, in order to unlock the red-blue-white train route. This further includes: when a train enters the arrival / departure track and occupies the branch turnout section and the section tracks on both sides of the branch turnout section, an emergency unlocking method is set for the red-blue-white train route. The emergency unlocking method includes: When the short-circuit train route is not unlocked, the red, blue and white train route is not allowed to be unlocked through the emergency unlocking method; Once it is determined that the red, blue, and white train route is being crossed by another train, the emergency unlocking of the red, blue, and white train route can be initiated by pressing the emergency unlocking button corresponding to the emergency unlocking method. The emergency unlocking method is not allowed to be executed during the near-locking delayed unlocking period of the red, blue, and white train route, nor is it allowed to initiate the near-locking delayed unlocking during the emergency unlocking period, so as to ensure that the emergency unlocking process is not interrupted.

[0017] Preferably, the emergency unlocking method further includes: the emergency unlocking method has a delay; during the delay, if the train continues to run normally, and the branch switch section meets the three-point check unlocking conditions, it can be unlocked normally, and the process of the emergency unlocking method ends; the signal is not allowed to be reopened during the emergency unlocking method; if the signal is reopened after the condition that the red-blue-white train route is crossed by a train is met, the emergency unlocking of the red-blue-white train route is not allowed.

[0018] Preferably, it further includes: when the station signal control system is equipped with active transponders and sends authorized messages, setting the signal authorization message range of the entry warning transponder group, the entry transponder group and the exit transponder group in the active transponders, so as to protect the train through the authorized message information of the active transponders.

[0019] Preferably, the setting of the signal authorization message range for the inbound pre-announcement transponder group, the inbound transponder group, and the outbound transponder group in the active transponder specifically includes: For the aforementioned entry advance transponder group, the signal authorization message range includes two segments, one segment from the transponder to the entry signal, and the other segment from the entry signal to the protective terminal exit signal of the arrival / departure track turnout receiving route. For the aforementioned entry transponder group, the signal authorization message range is from this transponder to the protective terminal exit signal of the train receiving route on the arrival / departure track branch line; For the aforementioned departure transponder group, when processing a forward departure route, the signal authorization message range is from this transponder to the entry signal of the station ahead; when processing a reverse arrival route, the signal authorization message range is from this transponder to the departure signal at the other end of the arrival / departure track; if the signal of the red-blue-white route signal is closed, the signal authorization message range is from this transponder to the red-blue-white route signal. When processing a reverse train passing through a route, the signal authorization message range includes two segments: one segment is from this transponder to the exit signal at the other end of the arrival / departure track branching off, and the other segment is from the exit signal at the other end of the arrival / departure track branching off to the entry signal at the station ahead.

[0020] On the other hand, the present invention also provides a train control system for a departure / arrival track with red, blue, and white route signals, which is used to implement the above-mentioned train control method for a departure / arrival track with red, blue, and white route signals. The control system includes: The red-blue-white route signal control module is used to control the red-blue-white route signal to achieve various light displays, and different light displays correspond to different control signals. The arrival / departure track train reception / departure operation module is connected to the red, blue, and white route signal control module. It is used to set the beginning of the established train route to the arrival / departure track branching off, and to set the end of the train reception route or guiding reception route to the arrival / departure track branching off, and to determine the control signal corresponding to the red, blue, and white route signal. It can handle the train reception route or guiding reception route to the arrival / departure track branching off or the departure route from the arrival / departure track branching off in one go. The standby parking track train reception and departure operation module is connected to the red, blue and white route signal control module. It is used to set the beginning of the established train route to the standby parking track and the end of the train reception route to the standby parking track, and to determine the control signal corresponding to the red, blue and white route signal, and to process the train reception route to the standby parking track or the departure route from the standby parking track in one go.

[0021] Preferably, each end of the arrival / departure track is provided with an entry signal and two exit signals corresponding to the two entry signals. The route starting from the entry signal and blocked by the red-blue-white route signal is the short-distance train route, and the route starting from the red-blue-white route signal is the red-blue-white train route; the control system further includes: The red-blue-white train route unlocking module is connected to the red-blue-white train route signal control module. It is used to set different unlocking methods for the red-blue-white train route according to the unlocking status of the short-circuit train route or whether the red-blue-white train route is crossed by a train, so as to unlock the red-blue-white train route. The train arrival and departure operation authorization message module is connected to the red, blue and white route signal control module. It is used to set the signal authorization message range of the entry warning transponder group, the entry transponder group and the exit transponder group in the active transponder when the station signal control system sets active transponders and sends authorization messages, so as to protect the train through the authorized message information of the active transponder.

[0022] An electronic device includes a processor and a memory, wherein a computer program is stored in the memory, and when the computer program is executed by the processor, it implements the above-described train control method for setting red, blue and white route signals on arrival and departure track branching off.

[0023] A readable storage medium storing a computer program, which, when executed by a processor, implements the above-described train control method for setting up red, blue, and white route signals on arrival / departure track branch lines.

[0024] Compared with the prior art, the present invention has the following beneficial effects: 1. The train control method and system for arrival and departure track branching off with red, blue and white route signals provided by the present invention realizes the system's signal control, route management and active transponder message transmission under the special station type where red, blue and white route signals and spare parking tracks are set up on the arrival and departure track branching off the railway station. 2. The control method and system provided by this invention ensure that maintenance trains and faulty trains in the section can quickly enter the station and drive into the backup parking track through a single receiving operation, and no shunting operation is required when departing, which meets the needs of one departure to the section. This greatly improves the transportation organization efficiency of freight railways during normal operation and special operations, and has a complete safety protection logic, which enhances the overall safety of the station trackside signal control system.

[0027] Given the problems of traditional arrival / departure track branching designs in existing technologies, such as operational requirements for train arrival / departure on standby parking tracks and complex interlocking relationships that existing train computer interlocking systems cannot meet, this embodiment proposes a train control method and system for arrival / departure track branching tracks equipped with red-blue-white route signals. This method is suitable for freight railway stations with special station types that install red-blue-white route signals on arrival / departure track branching tracks, and meets the transportation organization requirements of freight railways. This embodiment can be applied to station computer-based interlocking (CBI) control systems and train control center and interlocking integrated system (TIS) systems, thereby realizing the train arrival / departure track and standby parking track's operational requirements, ensuring the safety protection of arrival / departure track branching, and ensuring safe integration with station interlocking functions.

[0028] On the one hand, refer to Figure 1 and Figure 2 As shown, Figure 2X represents the downbound entry signal; XII represents the downbound exit signal; X3 represents the downbound exit signal of the spare parking track; S represents the upbound entry signal; SII represents the upbound exit signal; S3 represents the upbound exit signal of the spare parking track; IIG represents the main track section; WG represents the section without a turnout; D1 represents the downbound red-blue-white route signal; D2 represents the upbound red-blue-white route signal. This embodiment provides a train control method for arrival / departure track branching off with red, blue, and white approach signals. It is used in freight railway stations with arrival / departure track branching off and a spare parking track. The arrival / departure track branching off includes a branching turnout section, with red, blue, and white approach signals at both ends of the branching turnout section. Each end of the arrival / departure track branching off has an entry signal and two exit signals corresponding to the two entry signals. The spare parking track has an exit signal. The method includes: controlling the red, blue, and white approach signals to display various light signals, with different light displays corresponding to different control signals; setting the beginning of the established train route; and setting a train receiving route or guiding train receiving. The route's endpoint is determined, and the corresponding control signal for the red, blue, and white route signal is identified. This enables the simultaneous processing of train receiving routes or guiding receiving routes to the departure / arrival track branching off, or train departure routes from the departure / arrival track branching off, as well as the simultaneous processing of train receiving routes to the spare parking track or train departure routes from the spare parking track. Routes starting from the station entry signal and blocked by the red, blue, and white route signal are designated as short-connection routes, while routes starting from the red, blue, and white route signal are designated as red, blue, and white train routes. Different unlocking methods for the red, blue, and white train routes are set based on the unlocking status of the short-connection route or whether the red, blue, and white train route is being crossed by a train, in order to unlock the red, blue, and white train routes. When the station signal control system is equipped with active transponders and sends authorized messages, it sets the signal authorization message range of the entry warning transponder group, the entry transponder group and the exit transponder group in the active transponders, so as to protect the train through the authorized message information of the active transponders.

[0029] In this embodiment, regarding the design of the control function of the red-blue-white route signal, the control of the red-blue-white route signal to achieve multiple light displays, with different light displays corresponding to different control signals, specifically includes: controlling the red-blue-white route signal to achieve three light displays through the fully electronic execution module in the computer interlocking system or the integrated train control interlocking control system, including: when the red-blue-white route signal opens the train prohibition signal, the red-blue-white route signal illuminates a red light; when a shunting route is initiated from the red-blue-white route signal and the red-blue-white route signal opens the train permission signal, the red-blue-white route signal illuminates a white light; when a train route to the arrival / departure track or the spare parking track is initiated through the red-blue-white route signal and the red-blue-white route signal opens the train permission signal, the red-blue-white route signal illuminates a blue light.

[0030] In this embodiment, regarding the design of the arrival / departure track branching-out track for train reception and departure operations, the arrival / departure track branching-out track is divided into two storage track sections and an intermediate branching turnout section because of the intermediate branching-out track branching-out track branching-out. According to operational needs, freight trains are generally long in formation, and when they are completely stopped on the track, they usually need to occupy the entire arrival / departure track branching-out track. Therefore, there is no need for the train to stop in front of the red-blue-white route signal after entering the arrival / departure track branching-out track. When receiving a train on the arrival / departure track branching-out track, the train should be directly entered in front of the departure signal in the same direction on the arrival / departure track branching-out track. Therefore, when processing the train reception route to the arrival / departure track branching-out track, the red-blue-white route signal should be lit with the blue light. In this embodiment, the design for train reception and departure operations on the arrival / departure track branching off includes: controlling the operation of the computer interlocking system or the integrated train control and interlocking system to not establish a separate train route starting from the red, blue, and white signals; setting the endpoint of the train reception route to the arrival / departure track branching off to the exit signal on the same direction blocking the station on the track, and determining that the red, blue, and white route signal is open to allow trains to depart, thereby processing the train reception route to the arrival / departure track branching off in one go; setting the endpoint of the guiding reception route to the arrival / departure track branching off to the red, blue, and white route signal on the same direction blocking the station on the track, thereby processing the guiding reception route to the arrival / departure track branching off in one go, ensuring the flexibility of manual guiding reception operations. The departure signal is set as the starting point for the departure route from the departure signal to the railway section between the departure signal and the adjacent station. No departure route starting from the red-blue-white approach signal is established. Instead, the departure route is processed from the departure signal to the railway section, thus achieving a one-time processing of the departure route from the arrival / departure track to the branch line, ensuring the uniform principle that all train arrival and departure operations are processed in one go. When processing the guiding train arrival route to the branch line of the arrival / departure track, it is not necessary to confirm whether the red-blue-white approach signal has given a train permission signal. In specific implementation, the station duty officer processes the train arrival route from the arrival signal to the same-direction blocking departure signal in one go. The train enters the station according to the permission signal of the arrival signal, runs to the middle of the track, then crosses the blue light permission signal of the red-blue-white approach signal, and continues running after being positioned at the middle branch line, ensuring that long-formation trains can completely enter the entire track. Finally, the train stops in front of the same-direction blocking departure signal, completing the train arrival operation.

[0031] In this embodiment, the design of the train reception and departure operation function on the spare parking track is to meet the operational needs of special trains in the section being able to enter the spare parking track in one go, and to depart from the spare parking track in one go to the section. The spare parking track is equipped with a departure signal; the establishment of the starting point of the established train route and the setting of the ending point of the train reception route, and the determination of the control signals corresponding to the red, blue, and white route signals, to realize the one-time processing of train reception routes to the spare parking track or departure routes from the spare parking track, specifically includes: controlling the operation display on the computer interlocking system or the integrated train control interlocking system to not separately establish a train route from the red, blue, and white signals to the spare parking track; setting the ending point of the train reception route to the spare parking track as a departure signal blocking in the same direction on the spare parking track; and determining the red, blue, and white route signal to open the train permission signal, thereby realizing the one-time processing of departure routes from the arrival / departure track branching off. In practice, the station duty officer processes the train reception route from the entrance signal to the backup parking track's obstruction departure signal in one go. The train enters the station based on the permission signal from the entrance signal, runs to the middle of the track, then crosses the blue light permission signal of the red-blue-white route signal, and continues running through the track switch in the opposite direction, ensuring that the faulty train can fully access the backup parking track in one go. The route from the backup parking track to the red-blue-white route signal and the route from the red-blue-white route signal to the railway section between adjacent stations are combined into a combined train route. The departure route from the backup parking track through the red-blue-white route signal to the railway section is processed in one go using the combined train route.

[0032] Considering that all trains entering and exiting the backup parking track are either not equipped with ATP (Automatic Train Protection) systems or have malfunctioning ATP systems, the train arrival and departure routes on the backup parking track do not have train control system functions and do not require the transmission of active transponder messages or route authorization information. Ground signals serve as the operational credentials. When processing a train arrival route to the backup parking track, the entry signal remains illuminated; when processing a train departure route from the backup parking track, the departure signal remains illuminated.

[0033] In this embodiment, regarding the unlocking design of the red-blue-white route, according to the principle of the integrity of the receiving route, the train route starting with the red-blue-white route signal cannot be handled separately; it is part of the receiving route, and generally, it cannot be unlocked separately during route unlocking. Different unlocking methods are set for the red-blue-white train route based on its unlocking status or whether it is being blocked by a train, specifically including: When unlocking is performed by operating the total cancellation / total human release / area fault release method, if the short-connection train route is not unlocked, operating the total cancellation / total human release / area fault release on the human-machine interface device of the computer interlocking system or the train control interlocking integrated control system is only used to close the signal and cannot unlock the red, blue and white train route. The red, blue and white train route is unlocked by operating the total cancellation / total human release / area fault release of the station entry signal.

[0034] When unlocking via normal train operation, if the short-circuit train route is not unlocked, the red, blue, and white train route cannot be unlocked via normal train operation; if the short-circuit train route is unlocked, the red, blue, and white train route can be unlocked via normal train operation.

[0035] When the short-connection route is canceled or unlocked, the station duty officer's individual operation of the "general cancellation / general unlock" function on the red, blue, and white route signals is ineffective. The entire receiving route to the arrival / departure tracks must be unlocked at once by operating the "general cancellation / general unlock" function of the entry signal at the beginning of the receiving route. Similarly, when the receiving route is in normal operation or undergoing a malfunction unlock, as the train moves, the sections on the short-connection route are unlocked sequentially first, followed by the sections on the train route originating from the red, blue, and white route signals. This ensures absolute safety and avoids the dangerous scenario of head-on unlocking.

[0036] When a train enters the departure / arrival track and occupies the branch turnout section and the section tracks on both sides of the branch turnout section, an emergency unlocking method is set for the red-blue-white train route. This emergency unlocking method includes: when the short-connection train route is not unlocked, the red-blue-white train route is not allowed to be unlocked using this emergency unlocking method. When it is determined that the red-blue-white train route is being blocked by another train, the emergency unlocking of the red-blue-white train route can be initiated by pressing the emergency unlocking button corresponding to the emergency unlocking method. During the near-locking delayed unlocking period of the red-blue-white train route, the emergency unlocking method is not allowed to be executed, nor is the near-locking delayed unlocking process allowed during the emergency unlocking period, to ensure that the emergency unlocking process is not interrupted. The emergency unlocking method has a time delay. During the delay, if the train continues to run normally and the branching turnout section meets the three-point check unlocking conditions (the three-point check unlocking conditions include: the section ahead is clear: the section the train must pass through must be clear; the section is occupied: the train must occupy the current section; the section behind is clear: the section the train must pass through behind must be clear), the turnout can be unlocked normally, and the emergency unlocking process ends. Reopening the signal is not allowed during the emergency unlocking process. If a signal reopening is performed after the condition that the red-blue-white train route is blocked by a train is met, emergency unlocking of the red-blue-white train route is not allowed.

[0037] In practice, the emergency unlocking process for extra-long trains entering the arrival / departure tracks is as follows: After the receiving route is completed and the extra-long train has fully entered the arrival / departure tracks, and the short-connection route has been unlocked, meeting the primary condition for emergency unlocking, the extra-long train then crosses the red-blue-white route signaling structure, fulfilling the crossing condition. The station duty officer presses the emergency unlocking button, initiating the emergency unlocking of the red-blue-white route and starting the emergency unlocking countdown. The design that "the emergency unlocking method is not allowed to be executed during the near-locking delayed unlocking period of the red-blue-white train route, nor is it allowed to initiate near-locking delayed unlocking during the emergency unlocking period of the red-blue-white train route" ensures that the emergency unlocking process will not be interrupted by other delayed unlocking methods. When the countdown ends, the red-blue-white route will have completed the emergency unlocking process. In addition, during emergency unlocking, if required by the operation, the extra-long train can continue to run (such as departing past the previous departure signal or carrying out shunting operations). As the extra-long train continues to run, the turnout section of the track can also be unlocked normally, thus ending the emergency unlocking process ahead of schedule.

[0038] In this embodiment, the design of the authorization message for the red, blue, and white approach signal tracks for train arrival and departure operations also considers the degradation processing of the train control system when situations such as train-to-ground wireless communication failure or moving block failure occur in the application of the moving block train control system. The station's active transponder authorization message transmission function is precisely to ensure that the train can still be protected with the authorized message information of the active transponder when the moving block train control system is degraded. When the station signal control system has the active transponder authorization message transmission function, it is used for scenarios where red, blue, and white approach signals are set up on the arrival and departure track branching track. The setting of the signal authorization message range for the station advance announcement transponder group, the station entrance transponder group, and the station exit transponder group specifically includes: for the station advance announcement transponder group, the signal authorization message range includes two segments, one segment from the transponder itself to the station entrance signal, and the other segment from the station entrance signal to the protection terminal exit signal of the arrival and departure track branching track for train arrival and departure. For the entry transponder group, the signal authorization message range extends from the transponder to the exit signal of the receiving route on the arrival / departure track. For the exit transponder group, when processing a forward departure route, the signal authorization message range extends from the transponder to the entry signal of the preceding station. When processing a reverse receiving route, the signal authorization message range extends from the transponder to the exit signal at the other end of the arrival / departure track; if the red-blue-white route signal is closed, the signal authorization message range is shortened to the transponder to the red-blue-white route signal. When processing a reverse receiving route, the signal authorization message range includes two segments: one segment extends from the transponder to the exit signal at the other end of the arrival / departure track, and the other segment extends from the exit signal at the other end of the arrival / departure track to the entry signal of the preceding station.
