Description

Technical Field

[0001] This invention relates to the field of train control technology, and in particular to a method, apparatus, device, and storage medium for generating train operation permits. Background Technology

[0002] The Radio Block Center (RBC) is the core equipment of the train control system. It obtains route and block section status information from the interlocking equipment, calculates train movement permits based on the train's position, and sends these permits wirelessly to the onboard equipment to ensure safe train operation. When a train's pending route is abnormal, the starting signal of that route cannot open properly, the route status sent from the interlocking equipment to the RBC is also abnormal, and the RBC's calculated movement permits will not cover the pending route, preventing the train from entering it. In other words, the train control system has low equipment fault tolerance and poor system availability.

[0003] In such situations, the train driver has to manually switch the train's operating mode to get the train onto the route. This significantly impacts the efficiency of station operations. Summary of the Invention

[0004] This invention provides a method, apparatus, device, and storage medium for generating train operation permits to solve the problem of trains being unable to enter the route and continue operating in abnormal route scenarios, thereby improving the operational efficiency of station operations and enhancing the equipment fault tolerance and system availability of the train control system.

[0005] According to one aspect of the present invention, a method for generating a vehicle permit is provided, the method being performed by a radio block center, comprising:

[0006] In the event of an abnormality in the target train's pending route, the train route status of the target train is obtained from the interlocking equipment; wherein, the train route status is a locked guiding route, a guiding route, or unknown;

[0007] Based on the train route status, a target train operation permit is generated through the operation permit generation mechanism.

[0008] According to another aspect of the present invention, a vehicle permit generation device is provided, the device being deployed in a radio block center, comprising:

[0009] The train route status acquisition module is used to acquire the train route status of the target train from the interlocking equipment when the target train's pending route is abnormal; wherein, the train route status is a locked guiding route, a guiding route, or unknown;

[0010] The target train operation permit generation module is used to generate the target train operation permit based on the train route status and through the train operation permit generation mechanism.

[0011] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0012] At least one processor;

[0013] and a memory communicatively connected to at least one processor; wherein,

[0014] The memory stores a computer program that can be executed by at least one processor, such that the at least one processor is able to perform the vehicle permit generation method according to any embodiment of the present invention.

[0015] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the vehicle permit generation method of any embodiment of the present invention.

[0016] According to another aspect of the present invention, a computer program product is provided, comprising a computer program that, when executed by a processor, implements the vehicle permit generation method of any embodiment of the present invention.

[0017] The technical solution of this invention, when the pending route of the target train is abnormal, obtains the train route status of the target train from the interlocking equipment; wherein, the train route status is a locked guiding route, a guiding route, or unknown; based on the train route status, a target train operation permit is generated for the target train through a train operation permit generation mechanism. In the above technical solution, in the scenario of route abnormality, the radio block center generates a target train operation permit for the target train based on the train route status of the target train obtained from the interlocking equipment. This allows the target train to still enter the route and continue running even in the event of route abnormality, solving the problem that trains cannot enter the route and continue running in the scenario of route abnormality. This ensures that train operation is not affected by route abnormality, thereby improving the operational efficiency of station operations and increasing the equipment fault tolerance and system availability of the train control system.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0027] It should be noted that the terms "target," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] Example 1

[0029] Figure 1 This is a flowchart of a train operation permit generation method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where trains cannot enter the route due to route abnormalities. This method can be executed by a train operation permit generation device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, this method is executed by the radio blocking center and includes:

[0030] S101. In the event of an abnormal pending route for the target train, obtain the train route status of the target train from the interlocking equipment; wherein, the train route status is a locked guiding route, a guiding route, or an unknown route.

[0031] Here, "target train" refers to the train to be routed. "Pending route" refers to the route that the target train needs to take. "Pending route anomaly" refers to a situation where the pending route prevents the target train from passing normally; optionally, pending route anomalies include tracks in the pending route being occupied, turnout malfunctions in the pending route, and discrepancies between the actual state of the turnouts and their detected state. Here, "turnout detected state" refers to the state of the turnouts detected by the turnout detection equipment.

[0032] It should be noted that the status of a turnout includes a fixed state, a reversed state, and an unknown state. A fixed state means the turnout is open in the direction of train travel; a reversed state means the turnout is open in the direction of train travel; and an unknown state means the open direction of the turnout is uncertain.

[0033] It should be noted that when a turnout malfunctions in a pending route, the train dispatcher will manually correct the turnout malfunction. This means the dispatcher will move the malfunctioning turnout to its correct position and, after confirming through on-site observation that the malfunctioning turnout has been rotated into place, will activate the guide signal light at the starting signal of the pending route, releasing the guide signal. The starting signal refers to the signal located at the beginning of the pending route.

[0034] Specifically, in the event of an abnormality in the target train's pending route, if the abnormality is due to a track being occupied, the train route status obtained by the radio block center from the interlocking equipment will be a locked guiding route; if the abnormality is due to a turnout fault in the pending route, the train route status obtained by the radio block center from the interlocking equipment will be a guiding route; if the abnormality is due to a discrepancy between the actual turnout status and the turnout detection status, the train route status obtained by the radio block center from the interlocking equipment will be unknown.

[0035] S102. Based on the train route status, generate the target train's target train's train operation permit through the train operation permit generation mechanism.

[0036] Among them, the target train operation permit refers to the train operation permit for the target train, which is used to clarify the safe operating range and restrictions of the target train under specific line conditions. The train operation permit generation mechanism refers to the mechanism used to generate train operation permits.

[0037] Specifically, after receiving the train route status of the target train, the radio block center triggers its internal train operation permission generation mechanism to generate the target train operation permission.

[0038] It should be noted that the target train travel permit generated by the radio block center is a travel permit with a guide mode curve speed limit.

[0039] The technical solution of this invention, when the pending route of the target train is abnormal, obtains the train route status of the target train from the interlocking equipment; wherein, the train route status is a locked guiding route, a guiding route, or unknown; based on the train route status, a target train operation permit is generated for the target train through a train operation permit generation mechanism. In the above technical solution, in the scenario of route abnormality, the radio block center generates a target train operation permit for the target train based on the train route status of the target train obtained from the interlocking equipment. This allows the target train to still enter the route and continue running even in the event of route abnormality, solving the problem that trains cannot enter the route and continue running in the scenario of route abnormality. This ensures that train operation is not affected by route abnormality, thereby improving the operational efficiency of station operations and increasing the equipment fault tolerance and system availability of the train control system.

[0040] Example 2

[0041] Figure 2A This is a flowchart of a train operation permit generation method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further optimizes the step of "generating a target train operation permit according to the train route status through a train operation permit generation mechanism," providing an optional implementation scheme. It should be noted that parts not detailed in this embodiment can be referred to in the relevant descriptions of other embodiments. For example... Figure 2A As shown, this method is executed by the radio blocking center and includes:

[0042] S201. In the event of an abnormality in the target train's pending route, obtain the train route status of the target train from the interlocking equipment.

[0043] S202. Check whether the train route status is a locked guide route.

[0044] Specifically, the radio block center detects whether the train route status is a locked guide route; if the train route status is detected as a locked guide route, then S203 and S204 are executed; otherwise, S205 is executed.

[0045] S203. Obtain the locking guidance route information from the interlocking equipment.

[0046] The locked guidance route information includes the starting point of the pending route, the ending point of the pending route, and the turnout status information and track occupancy information between the starting point and the ending point of the pending route.

[0047] Specifically, if the radio block center detects that the train route is a locked guide route, it obtains the locked guide route information from the interlocking equipment.

[0048] For example, see Figure 2B ,at present Figure 2B In the station topology diagram, a train OBU2 is parked on track III, waiting to be joined by train OBU1. Train OBU1 is approaching signal B in Full Supervision (FS) mode. If the target train is train OBU1 and its pending route is B->V3, the anomaly in the target train's pending route is that the track in the pending route is occupied. Therefore, the radio block center obtains the following locked guide route information from the interlocking equipment: the starting point of the pending route is signal B, the ending point of the pending route is signal V3, the turnout status information between signal B and signal V3 includes the turnout status of turnout No. 2, turnout No. 8, and turnout No. 10, and the track occupancy information between signal B and signal V3 is that track III is occupied. It should be noted that the turnout status of turnouts No. 2, No. 8, and No. 10 between signal B and signal V3 is all in the positioning state.

[0049] It should also be noted that, Figure 2B BG1 to BG17 are transponders, 101a, 101b, A, B, C, D, K1, K2, K3, K4, V1, V2, V3, and V4 are signals, I, II, III, and IV are tracks, and 1, 2, 3, 4, 5, 6, 7, 8, 10, and 12 are turnsouts.

[0050] S204. Based on the locked guidance route information, generate the target train's target train's train operation permit through the train operation permit generation mechanism.

[0051] Specifically, the radio block center generates the target train's traffic permit based on the locked guidance route information and the real-time operating location information of the target train through the traffic permit generation mechanism.

[0052] S205. Check whether the train's route status is a guiding route.

[0053] Specifically, the radio block center detects whether the train route status is a guiding route; if the train route status is detected as a guiding route, S206 and S207 are executed; otherwise, S208, S209 and S210 are executed.

[0054] S206. Obtain the guidance signal of the starting signal of the pending route and the turnout status of each turnout from the interlocking equipment.

[0055] Specifically, if the wireless block center detects that the train route status is a guiding route, it obtains the guiding signal of the starting signal of the pending route and the turnout status of each turnout from the interlocking equipment.

[0056] For example, see Figure 2C ,at present Figure 2C In the station topology diagram, a train OBU2 is parked on track III, waiting to be joined by train OBU1. Train OBU1 is approaching signal B in Full Supervision (FS) mode, but turnout No. 2 is faulty. If the target train is train OBU1 and its planned route is B->V3, then the abnormality in the planned route is due to a turnout fault. In this case, the train dispatcher moves turnout No. 2 in the planned route B->V3 to its designated position, ensuring that the opening direction of turnout No. 2 is directly in the direction of the target train. After confirming by observation that turnout No. 2 has been turned into position, the guide signal light of the starting signal (i.e., signal B) in the planned route is turned on to release the guide signal. In this case, the radio block center obtains the train route status of the target train from the interlocking equipment as the guiding route. Then, the radio block center obtains the guiding signal of the starting signal (i.e., signal B) of the route B->V3 to be arranged from the interlocking equipment, as well as the turnout status of turnouts No. 2, No. 8 and No. 10 in the route B->V3 to be arranged.

[0057] S207. Based on the guidance signals of the starting signal of the pending route and the turnout status of each turnout, generate the target train's train operation permit through the train operation permit generation mechanism.

[0058] Specifically, the wireless block center generates the target train's train operation permit through a train operation permit generation mechanism, based on the guidance signals of the starting signal of the pending route and the turnout status of each turnout, combined with the real-time running location information of the target train.

[0059] S208. Obtain all available routes associated with the starting signal of the route in the pending route from the station topology map.

[0060] Optional routes refer to routes in the station topology map that can be used as the target train route. It should be noted that the station topology map is stored in the radio block center and is used to describe the connection relationships and functional logic of key equipment in the station (such as tracks, switches, signals, and transponders).

[0061] Specifically, if the radio block center detects that the train route status is unknown, it will obtain all possible routes from the station topology map, with the starting signal of the route in the pending route as the starting point.

[0062] For example, see Figure 2C ,at present Figure 2C In the station topology diagram, a train OBU2 is parked on track III, waiting to be joined by train OBU1. Train OBU1 is approaching signal B in Full Supervision (FS) mode. However, the actual state of turnout 2 does not match the turnout detection state. For example, the actual state of turnout 2 is in the positioning state, while the turnout detection state is unknown. If the target train is train OBU1 and its pending route is B->V3, the anomaly in the pending route is that the actual state of the turnout in the pending route does not match the turnout detection state. Therefore, the radio block center obtains the unknown train route status from the interlocking equipment. Consequently, the radio block center obtains from the station topology diagram all possible routes with the starting signal of the pending route (i.e., signal B) as the starting point: B->V1, B->V2, B->V3, and B->V4.

[0063] S209. Through the vehicle permit generation mechanism, generate vehicle permits for each selectable route.

[0064] Specifically, for each selectable route, the radio block center generates a target train permit based on the route information of the selectable route and the real-time operating location information of the target train through a train permit generation mechanism.

[0065] S210. Based on the driving permit screening criteria, determine the target driving permit for the target train from the driving permits corresponding to each selectable route.

[0066] The driving permit screening criteria can be preset according to actual business needs or the expert experience of those skilled in the art, and the embodiments of the present invention do not impose specific limitations on them. For example, based on the expert experience of those skilled in the art, the following driving permit screening criteria are determined: 1) the driving permit has the shortest authorized length; 2) the driving permit has the lowest static speed limit of the static speed curve of the line; 3) the driving permit has the lowest uphill or highest downhill slope of the optional route.

[0067] Specifically, the radio block center will identify the train permits that meet the train permit screening criteria from the train permits corresponding to each selectable route as the target train permits.

[0068] The technical solution of this invention addresses the following scenario: In the event of a route anomaly, when the received train route status is a locked guiding route, the radio block center generates a target train permit based on the locked guiding route information using a train permit generation mechanism. In this case, the target train's pending route is locked by the interlocking equipment, ensuring the target train's safety during operation and preventing any risks. Furthermore, when the received train route status is a guiding route, the radio block center generates a target train permit based on the guiding signal from the starting signal of the pending route and the turnout status of each turnout using the train permit generation mechanism. The solution also addresses the situation where the received train route status is unknown. The system obtains all possible routes associated with the starting signal of the route in the pending route from the station topology map; generates train permits for each possible route through the train permit generation mechanism; and determines the target train permit from the train permits corresponding to each possible route based on the train permit screening criteria. In this case, the radio block center comprehensively analyzes the train permits corresponding to all possible routes associated with the starting signal of the route in the pending route and selects the train permits that meet the train permit screening criteria as the target train permit. This ensures that the final target train permit meets the requirement of connecting the train to the track in a fault scenario while adhering to the fault-oriented safety principle, thereby improving the equipment fault tolerance and system availability of the train control system. In summary, the wireless block center generates target train operation permits for target trains using different methods based on the target train's route status. This allows the target train to continue operating even in the event of route anomalies, resolving the problem of trains being unable to enter and continue operating in route anomaly scenarios. This ensures that train operation is unaffected by route anomalies, thereby improving station operational efficiency and enhancing the equipment fault tolerance and system availability of the train control system. Furthermore, it also enables train reconnection operations.

[0069] Based on the above embodiments, as an optional embodiment of the present invention, after obtaining the target train's target travel permit, the target travel permit can also be sent to the target train so that the target train enters the route in On-Sight (OS) mode and runs to the track corresponding to the target travel permit according to the speed limit of the guidance mode curve in the target travel permit, thereby ensuring that the operation of the target train is not affected by route abnormalities.

[0070] Example 3

[0071] Figure 3 This is a schematic diagram of a train operation permit generation device provided in Embodiment 3 of the present invention. This embodiment is applicable to solving the situation where trains cannot enter the route due to abnormal route conditions. This device can be implemented in hardware and / or software and can be configured in electronic devices. Figure 3 As shown, the device includes:

[0072] The train route status acquisition module 301 is used to acquire the train route status of the target train from the interlocking equipment when the target train's pending route is abnormal; wherein, the train route status is a locked guiding route, a guiding route, or unknown.

[0073] The target train operation permit generation module 302 is used to generate the target train operation permit based on the train route status through the train operation permit generation mechanism.

[0074] The technical solution of this invention, when the pending route of the target train is abnormal, obtains the train route status of the target train from the interlocking equipment; wherein, the train route status is a locked guiding route, a guiding route, or unknown; based on the train route status, a target train operation permit is generated for the target train through a train operation permit generation mechanism. In the above technical solution, in the scenario of route abnormality, the radio block center generates a target train operation permit for the target train based on the train route status of the target train obtained from the interlocking equipment. This allows the target train to still enter the route and continue running even in the event of route abnormality, solving the problem that trains cannot enter the route and continue running in the scenario of route abnormality. This ensures that train operation is not affected by route abnormality, thereby improving the operational efficiency of station operations and increasing the equipment fault tolerance and system availability of the train control system.

[0075] Optionally, the target driving permit generation module 302 is specifically used for:

[0076] If a locked pilot route is detected, the locked pilot route information is obtained from the interlocking equipment.

[0077] Based on the locked guidance route information, a target train operation permit is generated through the train operation permit generation mechanism.

[0078] Optionally, the target driving permit generation module 302 is specifically used for:

[0079] If the train route status is detected as a guiding route, the guiding signal of the starting signal of the pending route and the turnout status of each turnout are obtained from the interlocking equipment.

[0080] Based on the guidance signals from the starting signals of the pending routes and the status of each turnout, the target train's traffic permit is generated through the traffic permit generation mechanism.

[0081] Optionally, the target driving permit generation module 302 is specifically used for:

[0082] If the train route status is detected as unknown, all possible routes associated with the starting signal of the route in the pending route are obtained from the station topology map;

[0083] The driving permit generation mechanism generates driving permits for each selectable route.

[0084] Based on the driving permit screening criteria, the target driving permit for the target train is determined from the driving permits corresponding to each selectable route.

[0085] Optionally, abnormalities in the pending route include tracks in the pending route being occupied, turnout malfunctions in the pending route, and discrepancies between the actual state of the turnouts in the pending route and the turnout detection state.

[0086] Optionally, the locked guiding route information includes the starting point of the pending route, the ending point of the pending route, and the turnout status information and track occupancy information between the starting point and the ending point of the pending route.

[0087] The vehicle permit generation device provided in this embodiment of the invention can execute the vehicle permit generation method provided in any embodiment of the invention, and has the corresponding functional modules and beneficial effects for executing each vehicle permit generation method.

[0088] According to embodiments of the present invention, the present invention also provides an electronic device, a readable storage medium, and a computer program product.
