Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a method and system for delay unlocking countdown processing of protection routes for train tracking. Background Technology

[0002] A protected route is a protected area set up for the safe operation of trains. It can only be released for use by other trains when the train no longer needs it. When a train approaches the stopping section in front of the protected route, a delayed unlock countdown will be triggered. If the train comes to a complete stop during this period, the onboard or Zone Controller (ZC) subsystem will transmit the stopping information to the Computer-Based Interlocking (CI) subsystem to unlock the route and end the countdown. If no stopping information is received, the CI subsystem will unlock the route after the countdown ends; or, the countdown will be reset to zero when the train leaves the stopping section.

[0003] While existing protection path delay unlock countdown methods possess basic functionality, they exhibit significant shortcomings in train tracking scenarios. When two trains simultaneously occupy a stopping section, even after the preceding train clears the section, the system cannot accurately clear the protection path delay unlock countdown for the preceding train, nor can it correctly set a new delay unlock countdown for the following train, as the stopping section remains occupied by the following train. If the following train mistakenly uses the preceding train's countdown, its protection path will unlock prematurely, affecting the following train's normal stopping and ultimately negatively impacting operational efficiency and safety.

[0004] Therefore, there is an urgent need for a protection route delay unlock countdown processing method and system for train tracking to solve the above problems. Summary of the Invention

If it is determined that the protection path delay unlock countdown function is running at the current moment and has not reached the end of the countdown, and if the current stabilization segment is cleared, or the stabilization segment and the continuation segment of the stabilization segment are both occupied, the protection path delay unlock countdown function is reset.

[0007] According to the present invention, a protection route delay unlock countdown processing method for train tracking is provided, the method further comprising: If it is determined that the protection path delay unlock countdown function is running at the current moment and has not reached the end of the countdown, and if the current stabilization segment is cleared, or the stabilization segment and the continuation segment of the stabilization segment are both occupied, then the protection path delay unlock countdown function is reset.

The delayed unlocking processing module is used to perform a zeroing operation on the protection path delayed unlocking countdown function when it is determined that the protection path delayed unlocking countdown function is running at the current moment and has not reached the end of the countdown. If the current stabilization section is cleared, or the stabilization section and the continuation section of the stabilization section are occupied at the same time, the module will perform a zeroing operation on the protection path delayed unlocking countdown function.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this 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 this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] In existing urban rail transit control systems, the CI (Completion and Intervention) subsystem can unlock the protected route based on the stopping information from the Automatic Train Protection (ATP) subsystem or the ZC (Train Control) subsystem, or the protected route delay unlocking information. If the CI subsystem does not receive stopping information, it can unlock the protected route when the delay unlocking countdown ends. Maintaining consistency between the timing of clearing the delay unlocking countdown for the preceding train's protected route and the timing of setting the delay unlocking countdown for the following train during train tracking, as when there is no train tracking, will significantly impact the operational efficiency of driverless lines.

[0021] A protected route is a protected area occupied to ensure train operation safety. It can only be released for other trains when the train no longer needs it. When a train reaches a stopping section before the protected route, a delayed unlock countdown is triggered. If the train comes to a stop during the countdown, the ATP or ZC subsystem sends the stopping information to the CI subsystem. The CI subsystem can then unlock the protected route and end the countdown based on this information. If no stopping information is received during the countdown, the CI subsystem can unlock the protected route when the countdown ends. If the train clears the stopping section, the delayed unlock countdown is immediately reset to zero.

[0022] While the existing method can achieve the protection route delay unlocking function, the stopping section may be occupied by two trains simultaneously during train tracking. When the leading train clears the stopping section, the stopping section is still occupied, making it impossible to correctly clear the protection route delay unlocking countdown for the leading train, nor to correctly set the protection route delay unlocking countdown for the following train. If the following train incorrectly uses the timing of the leading train, the protection route of the following train will be unlocked prematurely, affecting the stopping of the following train and thus affecting operational efficiency.

[0023] To address the problems existing in the prior art, this invention provides a method for processing the protection route delay unlock countdown for train tracking. This method can correctly set and clear the protection route delay unlock countdown for the preceding and following trains, thereby correctly locking the protection route for the following train. The correct locking of the protection route can ensure the safety of train operation and the efficiency of stopping.

[0024] Figure 1 This is a flowchart illustrating the protection route delay unlock countdown processing method for train tracking provided by the present invention, as shown below. Figure 1 As shown, the present invention provides a method for delay unlocking countdown processing of protection routes for train tracking, comprising: Step 101: Determine the protection route delay unlocking duration corresponding to the target train based on the train type of the target train.

[0025] In this invention, the protection route delay unlocking duration is determined based on the target train type, such as whether it is a Continuous Train Control (CTC) type or a non-CTC type train (e.g., unequipped trains, including malfunctioning cars, cars without position reports, and cars with position reports but not upgraded). In this invention, this duration is determined by comprehensively considering factors such as train characteristics, operating speed, and safety requirements to ensure that the train has sufficient time to perform necessary operations in the stationary section while ensuring safe train operation.

[0026] Step 102: If it is determined that the stopping section has been converted to an occupied state, or the stopping section is occupied, and the protection route ahead of the target train is available, the protection route delay unlock countdown function of the target train is triggered based on the protection route delay unlock duration.

[0027] In this invention, when it is determined that the stopping section has been converted to an occupied state or is occupied, and the protection route is in an available state, the protection route delay unlock countdown function will be triggered based on the protection route delay unlock duration. Specifically, if the stopping section is already occupied, and the protection route is determined to be available, it indicates that the protection route is ready for the target train and can be used at any time.

[0028] Step 103: When it is determined that the protection path delay unlock countdown function is running at the current moment and has not reached the end of the countdown, if the current stabilization segment is cleared, or the stabilization segment and the continuation segment of the stabilization segment are occupied at the same time, the protection path delay unlock countdown function is cleared.

[0029] In this invention, when it is determined that the protection route delay unlock countdown function is currently running but has not yet reached the end of the countdown, if the stopping section has been cleared (i.e., no train is occupying it), or if the stopping section and its continuation section are simultaneously occupied, a reset operation will be performed on the protection route delay unlock countdown function. The purpose of this step is to ensure that when the stopping section is occupied again, the correct delay unlock countdown can be re-triggered. Failure to reset may result in inaccurate countdown times, affecting the safety and efficiency of subsequent train operations. The reset operation ensures that when the stopping section is occupied again, the correct delay unlock countdown can be recalculated and triggered based on the new train type and status. By reasonably setting and triggering the protection route delay unlock countdown function, and by timely resetting the countdown, the safety of train operation and the efficiency of line operation are guaranteed.

[0030] The present invention provides a protection route delay unlock countdown processing method for train tracking, which ensures train operation safety and improves line operation efficiency by setting the start and reset time of the protection route delay unlock countdown.

[0031] Based on the above embodiments, the method further includes: If it is determined that the protection path delay unlock countdown function is running at the current moment and has not reached the end of the countdown, and if the stopping section at the current moment is cleared, or the stopping section and the continuing section of the stopping section are simultaneously occupied (i.e., the train is already in the process of leaving the stopping section), then the protection path delay unlock countdown function is reset.

[0032] In this invention, the protected route delay unlock countdown function serves as a safety mechanism to ensure that the train has sufficient time to perform necessary operations within the stopping section, and automatically unlocks the route after confirming safety, allowing subsequent trains to use it. The stopping section is a specific area where the train comes to a complete stop and performs relevant operations. The continuation section of the stopping section refers to an area directly connected to the stopping section and available for further train operations or preparation for departure.

[0033] Specifically, in this invention, when it is determined that the protection route delay unlock countdown function is running and has not yet reached the end of the countdown, it indicates that the target train is currently operating in or near the stationary section, and the protection route has not yet automatically unlocked. Simultaneously, it is also detected that the stationary section and its continuation section are occupied. In this situation, a reset operation is performed on the protection route delay unlock countdown function, indicating that the previous countdown will be canceled, and the protection route will not automatically unlock as originally planned. The purpose of the reset operation may be to reassess the current situation and ensure that the protection route is correctly locked after confirming safety, thereby guaranteeing the safety and efficiency of train operation.

[0034] Based on the above embodiments, determining the protection route delay unlocking duration corresponding to the target train according to the train type of the target train includes: Determine the train type of the target train; if the train type is a continuous train control type, generate the protection route delay unlocking time corresponding to the target train of the continuous train control type. If the train type is a non-continuous train control type, generate the protection route delay unlocking time corresponding to the target train of the non-continuous train control type.

[0035] In this invention, the train type of the target train is first determined. If the target train is a continuous train control type, a protection route delay unlocking time corresponding to that type of train will be generated. This time can be determined based on various factors such as the characteristics of the continuous train control system, the speed of the train, the length and complexity of the stopping section, and safety requirements.

[0036] If the target train is a non-continuous train control type, a protection route delay unlocking time corresponding to the non-continuous train control type will be generated. Similarly, this time will also take into account the characteristics of the non-continuous train control system to ensure the safe stopping of the train and the unlocking of the route.

[0037] Based on the above embodiments, the method further includes: If it is determined that the protection path delay unlock duration is zero, the stopping section is converted to an occupied state or is already occupied, and the protection path is in an available state, the protection path delay unlock countdown function is triggered based on the protection path delay unlock duration.

[0038] In this invention, when the protection route delay unlock duration is zero, it indicates that the target train has previously triggered the protection route delay unlock countdown, and that countdown has ended. At this point, the target train is no longer in the protection route delay unlock countdown state. Simultaneously, the stopping section is either in or has been converted to an occupied state. At this time, the protection route ahead of the target train is available, indicating that the protection route ahead of the target train (i.e., the train's path) is physically and logically available, and there are no obstacles or locked states preventing the target train from moving forward.

[0039] Furthermore, if all the above conditions are met, the protection route delay unlock countdown function of the target train is triggered based on the protection route delay unlock duration. The purpose of triggering the countdown function is to ensure that there is sufficient time for necessary preparation and checks before the target train can safely enter the stopping section, providing the target train with a clear and predictable time window to enter the section.

[0040] Based on the above embodiments, the method further includes: When the countdown of the protection path delay unlock countdown function has ended, the unlock operation of the protection path is triggered.

[0041] In this invention, when the countdown of the protected route delay unlock countdown function ends, it is determined that the countdown function has met the termination condition. The termination condition indicates that the train has completed all necessary operations in the stopping section and safety has been ensured, therefore the route can be safely unlocked. After determining that the unlock condition is met, the unlocking operation of the protected route is triggered. Through the unlocking operation, the previously locked or occupied route can be released, allowing the train to safely enter the route, preparing the target train to leave the stopping section and continue its journey.

[0042] Based on the above embodiments, the method further includes: Upon receiving the stop information from the onboard train automatic protection subsystem or the area controller subsystem, the protection path delay unlock countdown function meets the termination condition and triggers the unlocking operation of the protection path.

[0043] In this invention, upon receiving the stopping information, it is first confirmed that the train has come to a safe stop. Then, the protection route delay unlock countdown function meets the termination condition. In this invention, the termination condition is no longer simply the end of the countdown, but rather based on the fact that the train has come to a stop. Even if the countdown has not completely ended, as long as the train has come to a stop, it can be determined that the purpose of the protection route delay unlock has been achieved.

[0044] Furthermore, after confirming that the termination conditions are met, the unlocking operation of the protected route is triggered, allowing the train to safely enter the route.

[0045] Based on stationary information, this invention confirms that the protection route delay unlock countdown function meets the termination condition, and then triggers the unlocking operation of the protection route to ensure the safety and efficiency of train operation, thereby responding more flexibly to the actual state of the train.

[0046] In one embodiment, the protection route delay unlocking processing method for train tracking provided by the present invention will be described in its entirety, and the specific process is as follows: When the preceding vehicle reaches the stopping section, the protection route delay unlock countdown begins. When the preceding vehicle occupies both the stopping section and the section extending from the stopping section, the protection route delay unlock countdown is cleared. When the following vehicle's protection route is valid and the stopping section is occupied, the protection route delay unlock countdown begins. When the following vehicle clears the stopping section, or occupies both the stopping section and the section extending from the stopping section, the protection route delay unlock countdown is cleared.

[0047] In this embodiment, if the train is a CTC train, the countdown is performed using the CTC train protection route delay unlocking time; if the train is a non-CTC train, the countdown is performed using the non-CTC train protection route delay unlocking time.

[0048] Furthermore, if, during the delayed unlock countdown, a stopping information is received from the ATP subsystem or ZC subsystem and the protection path is idle, the protection path is immediately unlocked and the countdown ends; if the delayed unlock countdown reaches its end value and the protection path is idle, the protection path is immediately unlocked and the end value is maintained.

[0049] The protective route delay unlock countdown processing system for train tracking provided by the present invention will be described below. The protective route delay unlock countdown processing system for train tracking described below can be referred to in correspondence with the protective route delay unlock countdown processing method for train tracking described above.

Figure 2 As shown, this invention provides a protection route delay unlock countdown processing system for train tracking, including a delay unlock time generation module 201, a delay unlock countdown triggering module 202, and a delay unlock processing module 203. The delay unlock time generation module 201 determines the protection route delay unlock duration corresponding to the target train based on the train type. The delay unlock countdown triggering module 202, when determining that a stopping section has been converted to an occupied state, or that the stopping section is occupied, and the protection route ahead of the target train is available, triggers the protection route delay unlock countdown function of the target train based on the protection route delay unlock duration. The delay unlock processing module 203, when determining that the protection route delay unlock countdown function is running at the current moment and has not reached the end of the countdown, performs a zeroing operation on the protection route delay unlock countdown function if the stopping section at the current moment is cleared, or if the stopping section and its continuation section are simultaneously occupied.
