Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0028] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards in the relevant regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0029] First, the terms involved in one or more embodiments of the present application are explained.

[0030] CI: Computer Interlocking is a key component in the subway signal system. Its main function is to control and manage signals, switches, sections, routes, etc. on the line. It uses a two-by-two safety computer platform to achieve the correct interlocking control relationship between station equipment, select routes for trains running in its control area, and ensure safe operation of trains.

[0031] Locking: In order to ensure the safe operation of trains, a technical means is used to lock signals, switches, sections and routes in a specified state through an interlocking system.

[0032] Unlocking: When the interlocking system checks that the unlocking conditions are met, the locked status of signals, switches, sections and routes is released.

[0033] Protection section: In the signal system, the protection section is set up outside the route to prevent the train from side collision or head-on collision. It reduces the possibility of conflict between the advancing train and the normal operating train when the train advances due to the driver's erroneous operation outside the stop signal or insufficient braking performance of the train.

[0034] Route: The section of route that a train or shunting train passes through when running from one designated location to another designated location.

[0035] Axle counting section: Any two adjacent axle counters constitute an axle counting section.

[0036] Physical section: A closed section consisting of axle counting sections. For sections with switches, the physical section contains multiple axle counting sections.

[0037] ZC: Zone Controller is the core component of the signal system based on CBTC and is part of the ground equipment. It divides a line into several control areas, each of which is managed by a zone controller. In the area it is responsible for, the ZC is responsible for providing the train with movement authority (MA) to inform the train of the maximum distance it is allowed to move.

[0038] In rail transit, the route protection section is unlocked following the route status. When the train sequentially occupies the last physical section of the route, the delayed unlocking process of the protection section is triggered. After receiving the train stop information or a certain delay, the protection section is unlocked. The countdown for delayed unlocking of the protection section needs to be displayed in the interlocking area where the route is located. However, in the scenario where the route belongs to an adjacent interlocking and the protection section belongs to the current interlocking, the delayed unlocking countdown cannot be passed to the adjacent interlocking, and the protection section cannot be unlocked normally.

[0039] In actual applications, when the train is moving, its corresponding route will be determined, and the route will further determine the section ahead of the route as the route protection section. After the route corresponding to the train is determined, its corresponding route protection section will be set to a locked state. When the train sequentially occupies the last physical section of the route, the delayed unlocking process of the route protection section will be triggered. After a period of delay, the route protection section will be unlocked.

[0040] During this process, the countdown information of the delayed unlocking of the route protection section needs to be displayed in the second interlocking area where the target route is located. However, since the route protection section belongs to the first interlocking area, the second interlocking area cannot obtain the status information of the protection section. At the same time, the locking status of the route protection section is managed and controlled by the first interlocking area, resulting in the delayed unlocking countdown information of the route protection section cannot be sent to the second interlocking area, and the route protection section cannot be unlocked normally.

[0041] Based on this, in the present application, a method for unlocking a protection section of a cross-interlocking area approach route is provided. The present application also involves a train control system, a computing device, a computer-readable storage medium and a computer program product, which are described in detail one by one in the following embodiments.

[0042] Figure 1 A flowchart of a method for unlocking a cross-interlocking area route protection section according to an embodiment of the present application is shown. The method is applied to a train control system, which includes a first interlocking area and a second interlocking area. The route protection section is located in the first interlocking area, and the target route is located in the second interlocking area. Figure 2 , Figure 2 A schematic diagram of a scenario provided by an embodiment of the present application is shown, where a train moves from S1 to S2, S1-S2 is the target route, the target route is located in the second interlocking area, P2 and P3 are physical sections on the target route. P1 is the route protection section corresponding to the target route, and the route protection section is located in the first interlocking area. The method specifically includes the following steps:

[0043] Step 102: The second interlocking area sends the target segment occupancy information of the target physical segment corresponding to the target route to the first interlocking area.

[0044] The second interlocking area is the interlocking area to which the target route belongs, the target route is the route corresponding to the target train in the embodiment of the present application, the target physical section can be understood as the last physical section in the target route, and the target section occupancy information can be understood as the locking occupancy status information corresponding to the target physical section.

[0045] In the method provided in the embodiment of the present application, interlocking area data between the first interlocking area and the second interlocking area is added, that is, the information of the target approach is sent from the second interlocking area to the first interlocking area, and the last physical section corresponding to the target approach, that is, the target physical section, and the target section occupancy information are also sent to the first interlocking area, so that the first interlocking area can obtain the status information of the last physical section of the target approach in real time, thereby triggering the unlocking of the approach protection section according to the status information of the target physical section.

[0046] In the method provided in the embodiment of the present application, the target section occupancy information includes the locking status information of the target physical section and the train occupancy information, wherein the locking status information can be understood as whether the target physical section is in a locked state, and the train occupancy information can be understood as whether the target train has arrived at the target physical section.

[0047] In a specific implementation manner provided by the present application, before the second interlocking area sends the target segment occupancy information of the target physical segment corresponding to the target route to the first interlocking area, the method further includes:

[0048] The first interlocking area acquires at least one approach to be processed, wherein the approach to be processed includes an approach in the first interlocking area and an approach in the second interlocking area;

[0049] The first interlocking area determines the target route of the second interlocking area among the routes to be processed, and sends a request for obtaining the segment occupancy information of the target physical segment corresponding to the target route to the second interlocking area when the route protection segment corresponding to the target route is idle.

[0050] In actual applications, the second interlocking area may not directly send the target segment occupancy information corresponding to the target physical segment to the first interlocking area, but the first interlocking area sends a segment occupancy information acquisition request for the target physical segment to the second interlocking area, and the second interlocking area sends the target segment occupancy information of the target physical segment to the first interlocking area based on the segment occupancy information acquisition request item.

[0051] Specifically, the first interlocking area where the route protection section is located periodically traverses at least one pending route corresponding to the first interlocking area and the second interlocking area. The pending route refers to the route obtained by the first interlocking area, which includes the routes of the first interlocking area and the routes of the second interlocking area adjacent to the first interlocking area. The first interlocking area selects the target route that does not belong to the interlocking area from each pending route, and further determines whether the route protection section corresponding to the target route is idle. If the route protection section corresponding to the target route is idle, it is necessary to continue to check the target section occupancy information of the target physical section corresponding to the target route, that is, the first interlocking area sends a section occupancy information acquisition request for the target physical section to the second interlocking area.

[0052] After receiving the section occupancy information acquisition request, the second interlocking area acquires the target section occupancy information of the target physical section, and sends the target section occupancy information to the first interlocking area, so that the first interlocking area performs subsequent processing according to the target section occupancy information.

[0053] Step 104: The first interlocking area determines unlocking information of the approach protection section according to the target section occupancy information, and sends the unlocking information to the second interlocking area.

[0054] After the first interlocking area obtains the target section occupancy information, it is necessary to further determine the unlocking information of the route protection section according to the target section occupancy information. The unlocking information can be understood as the real-time unlocking information of the route protection section. In practical applications, the unlocking information includes immediate unlocking, section locking and delayed unlocking.

[0055] Immediate unlocking can be understood as the state of the route protection section is directly unlocked, section locking can be understood as the state of the route protection section remains locked, and delayed unlocking can be understood as the state of the progress protection section is unlocked after a preset time.

[0056] As explained in the above steps for the target section occupancy information, the target section occupancy information includes locking state information and train occupancy information;

[0057] The first interlocking zone determines the unlocking information of the approach protection zone according to the target zone occupancy information, including:

[0058] The first interlocking area determines the unlocking information of the route protection section according to the locking state information and the train occupancy information.

[0059] Specifically, the first interlocking area determines the unlocking information of the route protection section according to the locking state information and the train occupation information, including:

[0060] When the locking state information is unlocked, the first interlocking area determines that the unlocking information of the route protection section is immediately unlocked;

[0061] When the locking state information is locked and the train occupation information is unoccupied, the first interlocking area determines that the unlocking information of the route protection section is section locked;

[0062] When the locking state information is locked and the train occupation information is occupied, the first interlocking area determines that the unlocking information of the route protection section is delayed unlocking.

[0063] In practical applications, the first interlocking area should further determine the unlocking information corresponding to the route protection section based on the locking status information and train occupancy information of the target physical section.

[0064] First, it is necessary to determine whether the locking status of the target physical section is locked. If the locking status information is unlocked, it means that the target train has not yet arrived at the route, and the route protection section is behind the target physical section. If the target physical section has not been locked, it means that the route protection section does not need to be locked. The first interlocking area further determines that the unlocking information of the route protection section is directly unlocked.

[0065] Secondly, if the locking state of the target physical section is locked, it is necessary to further determine whether the target train has arrived at the target physical section. If the target train has not arrived at the target physical section, it means that the target train is still in the process of moving, and the first interlocking area determines that the unlocking information of the route protection section is section locked, that is, the route protection section continues to be locked. If the target train has arrived at the target physical section, the movement trend of the target train is gradually stopped. At this time, the route protection section is to prevent the train from rushing into the route protection section at too fast a speed. When the target train enters the target physical section, the delayed unlocking of the route protection section can be triggered, that is, the first interlocking area determines that the unlocking information of the route protection section is delayed unlocking. The specific implementation of delayed unlocking is realized by unlocking countdown. The unlocking countdown can be a pre-set fixed countdown, or it can be determined according to the speed of the target train. For example, the unlocking countdown can be a fixed 30 seconds, or it can be determined as the target train enters the target physical section. The faster the speed, the longer the unlocking countdown time.

[0066] In a specific implementation provided by the present application, when the locking state information is locked, the method further includes:

[0067] Acquire the approach direction of the target approach and acquire the locking direction of the target physical section;

[0068] When the route direction and the locking direction are consistent, determining whether the train occupation information is occupied;

[0069] When the approach direction and the locking direction are inconsistent, the first interlocking area determines that the unlocking information of the approach protection section is immediate unlocking.

[0070] In practical applications, when the locking state information of the target physical section is determined to be locked, it is also necessary to further determine the locking direction of the target physical section and the approach direction of the target approach. Figure 2, taking the target physical section P2 as an example, under normal circumstances, the target train travels from S1 to S2, then the direction of the target route is from right to left, and the locking direction of the target physical section P2 is determined at the same time.

[0071] If the locking direction of the target physical section P2 is also from right to left, that is, the locking direction of the target physical section is consistent with the route direction of the target route, the subsequent step of obtaining the train occupancy information of the target physical section is performed.

[0072] If the locking direction of the target physical section P2 is from left to right, it means that the target physical section P2 is locked in the opposite direction, which means that the corresponding train is traveling from left to right. In this case, the first interlocking area can determine that the unlocking information of the approach protection section P1 is immediate unlocking.

[0073] In a specific implementation manner provided in the present application, after the first interlocking area determines that the unlocking information of the approach protection section is delayed unlocking, the method further includes:

[0074] The first interlocking area obtains the train running status of the target train;

[0075] When the running state of the train is a stopped state, or the delay countdown of the delayed unlocking stops, the first interlocking area determines that the unlocking information of the approach protection section is immediate unlocking.

[0076] When the first interlocking area determines that the unlocking information of the route protection section is delayed unlocking, it is necessary to further determine the train running state of the target train. Specifically, the second interlocking area may transmit the train running state of the target train to the first interlocking area. The train running state specifically includes a running state or a stopped state.

[0077] After the first interlocking area determines that the unlocking information of the route protection section is delayed unlocking, the unlocking information of the route protection section can be further updated in combination with the train driving status of the train. Specifically, when the train driving status is stopped, it means that the train will no longer rush out of the target route. At this time, even if the unlocking countdown of delayed unlocking has not stopped, the unlocking information of the route protection section can be updated to immediate unlocking. In addition, when the delayed countdown of delayed unlocking stops (that is, the countdown returns to zero), it means that the delayed unlocking time specified by the first interlocking area for the target train meets the unlocking condition, that is, the unlocking information of the route protection section is updated to immediate unlocking.

[0078] In another specific embodiment provided in the present application, the method further comprises:

[0079] The first interlocking area obtains the train type of the target train;

[0080] Accordingly, when the running state of the train is a stopped state, or the delay countdown of the delayed unlocking stops, the first interlocking area determines that the unlocking information of the approach protection section is immediate unlocking, including:

[0081] If the train type is a non-communication train, the first interlocking area determines that the unlocking information of the route protection section is immediate unlocking when it is determined that the running state of the train is stopped or the delay countdown of the delayed unlocking stops;

[0082] If the train type is a communication train, the first interlocking area determines that the unlocking information of the route protection section is immediate unlocking when it is determined that the running state of the train is a stopped state.

[0083] In practical applications, the first interlocking area can further update the unlocking information of the route protection section according to the train type of the target train. The train type of the target train is generally divided into a communication train and a non-communication train. A communication train can be understood as a train that the interlocking can communicate with the regional controller, while a non-communication train is a train that the interlocking cannot communicate with the regional controller.

[0084] The first interlocking area can also receive the train type of the target train sent by the second interlocking area. When the train is a non-communication train, if the first interlocking area receives the train stop information for the target train sent by the second interlocking area, it can be determined that the train's driving state is stopped. At this time, even if the delayed countdown of the delayed unlocking has not stopped, the unlocking information of the route protection section can be updated to immediate unlocking. If the train stop information for the target train is not received, and the delayed countdown of the delayed unlocking stops, the unlocking information of the route protection section is updated to immediate unlocking. In the process of the unlocking information of the route protection section being delayed unlocking, the first interlocking area will also send the delayed countdown of the delayed unlocking to the second interlocking area in real time, so as to visualize the delayed countdown in the second interlocking area.

[0085] If the train is a communication train, if the first interlocking area receives the train stop information sent by the regional controller, it determines that the unlocking information of the route protection section is immediate unlocking. When the first interlocking area does not receive the train stop information sent by the regional controller, and the delay countdown of delayed unlocking has not stopped, the first interlocking area will also send the delay countdown of delayed unlocking to the second interlocking area in real time, so as to visualize the delay countdown in the second interlocking area.

[0086] In another specific embodiment provided in the present application, the method further comprises:

[0087] If the train type is a communication train, the first interlocking area sends an unlocking request to the regional controller when the delay countdown of the delayed unlocking stops and it is not determined that the running state of the train is a stopped state;

[0088] When receiving the unlocking instruction sent by the zone controller in response to the unlocking request, the first interlocking zone determines that the unlocking information of the approach protection section is immediate unlocking.

[0089] In this embodiment, further restrictions are imposed on communication trains. When the train type is a communication train, when the delay countdown of the delayed unlocking is stopped, but it cannot be determined that the train is in a stopped state, the route protection section cannot be unlocked directly. The first interlocking area needs to send a route protection section unlocking request to the regional controller. Only when the unlocking permission information sent by the regional controller is received, the unlocking information of the route protection section can be set to unlock immediately. When the train type of the target train is a communication train, it is necessary to further determine the unlocking information of the route protection section in combination with the information of the regional controller, so as to better ensure the safe and stable operation of the train.

[0090] Step 106: The second interlocking area receives and displays the unlocking information.

[0091] The above steps introduce different situations in which the first interlocking area determines the unlocking information of the approach protection section according to the target section occupancy information. After the first interlocking area determines the unlocking information of the approach protection section, it needs to be sent to the second interlocking area so that the second interlocking area can receive the unlocking information of the approach protection section. At the same time, the unlocking information of the approach protection section in the first interlocking area can also be displayed in the second interlocking area.

[0092] An unlocking method for a cross-interlocking area approach protection section provided in an embodiment of the present application is applied to a train control system, wherein the train control system includes a first interlocking area and a second interlocking area, the approach protection section is located in the first interlocking area, and the target approach is located in the second interlocking area, and the method includes the second interlocking area sending the target section occupancy information of the target physical section corresponding to the target approach to the first interlocking area; the first interlocking area determines the unlocking information of the approach protection section based on the target section occupancy information, and sends the unlocking information to the second interlocking area; the second interlocking area receives and displays the unlocking information. Through this method, the problem of unlocking the approach protection section in the scenario where the approach and the approach protection section belong to different interlocking areas can be solved, and the problem of difficulty in unlocking the cross-interlocking area approach protection section in the rail transit scenario can be solved. The running safety of trains in the rail transit scenario is improved, and the difficulty of managing the train control system is reduced.

It improves the running safety of trains in rail transit scenarios and reduces the difficulty of managing train control systems.

[0122] Step 402: The first interlocking area acquires at least one route to be processed, wherein the route to be processed includes the route of the first interlocking area and the route of the second interlocking area.

[0123] Step 404: the first interlocking area determines the target route of the second interlocking area from among the routes to be processed, and when the route protection section corresponding to the target route is idle, sends a request for obtaining the section occupancy information of the target physical section corresponding to the target route to the second interlocking area.

[0124] Step 406: The second interlocking area sends the locking state information and train occupancy information of the target physical section to the first interlocking area.

[0125] Step 408: When the locking state information is unlocked, the first interlocking area determines that the unlocking information of the approach protection section is immediate unlocking.

[0126] Step 410: When the locking state information is locked, obtain the locking direction of the target physical segment.

[0127] Step 412: When the approach direction and the locking direction are inconsistent, the first interlocking area determines that the unlocking information of the approach protection section is immediate unlocking.

[0128] Step 414: When the approach direction and the locking direction are consistent, determine whether the train occupancy information is occupied.

[0129] Step 416: When the train occupancy information is not occupied, the first interlocking area determines that the unlocking information of the route protection section is section locked.

[0130] Step 418: When the train occupation information is occupied, the first interlocking area determines that the unlocking information of the route protection section is delayed unlocking.

[0131] Step 420: The first interlocking area obtains the train type of the target train.

[0132] Step 422: If the train type is a non-communication train, the first interlocking area determines that the unlocking information of the approach protection section is immediate unlocking when it is determined that the train is in a stopped state or the delayed countdown of the delayed unlocking stops.

[0133] Step 424: If the train type is a communication train, the first interlocking area determines that the unlocking information of the route protection section is immediate unlocking when it is determined that the train is in a stopped state.

[0134] Step 426: If the train type is a communication train, the first interlocking area sends an unlocking request to the regional controller when the delayed countdown of the delayed unlocking stops and it is not determined that the train driving state is a stopped state.

[0135] Step 428: Upon receiving the unlocking instruction sent by the zone controller in response to the unlocking request, the first interlocking zone determines that the unlocking information of the approach protection section is immediate unlocking.

[0136] An unlocking method for a cross-interlocking area approach protection section provided in an embodiment of the present application is applied to a train control system, wherein the train control system includes a first interlocking area and a second interlocking area, the approach protection section is located in the first interlocking area, and the target approach is located in the second interlocking area, and the method includes the second interlocking area sending the target section occupancy information of the target physical section corresponding to the target approach to the first interlocking area; the first interlocking area determines the unlocking information of the approach protection section based on the target section occupancy information, and sends the unlocking information to the second interlocking area; the second interlocking area receives and displays the unlocking information. Through this method, the problem of unlocking the approach protection section in the scenario where the approach and the approach protection section belong to different interlocking areas can be solved, and the problem of difficulty in unlocking the cross-interlocking area approach protection section in the rail transit scenario can be solved. The running safety of trains in the rail transit scenario is improved, and the difficulty of managing the train control system is reduced.
