Description

Technical Field

[0001] This invention relates to the field of urban rail transit signal control, and in particular to a train route switching method and electronic equipment. Background Technology

[0002] Train route switching is a common operation in urban rail transit. The current standard procedure for train route switching is to first stop the train, then cancel the original route, and finally select and set a new route after the route cancellation delay. Although there is a segmented triggering mechanism for train routes, which only triggers the subsequent route when the train approaches the next switch, this mechanism only delays the implementation of the subsequent route as much as possible, providing room for modification in case of possible route changes (i.e., the affected area can be appropriately reduced when canceling a route).

[0003] Therefore, the existing train route operation has shortcomings and drawbacks. Specifically, as long as there is a route ahead of the train, the train route switching operation always requires the train to stop, cancel the original route, and set a new route, which takes too long and cannot make reasonable and effective use of existing route resources and system data for dynamic adjustment.

[0004] Given the above situation, how to solve the problem of excessively long train route switching operations and make reasonable use of existing route resources has become an urgent technical challenge. Summary of the Invention

[0005] This application provides a train route switching method and electronic equipment to solve the problem of excessively long train route switching operation time, and can make reasonable use of existing route resources for dynamic adjustment.

[0006] This application provides a train route switching method, including the following steps: receiving a command for a new train route; obtaining the directions of the original train route and the new route; if the directions of the original route and the new route are consistent, obtaining the starting point of the forward difference portion; if the starting point of the forward difference portion is located in front of the train head, sending the starting point of the forward difference portion as the endpoint of the movement authorization to the train; if receiving an accepted message from the train, releasing the route in front of the starting point of the forward difference portion; splicing the new route portion with the starting point of the forward difference portion as the starting point, and updating the movement authorization status; sending the updated movement authorization status to the train.

[0007] In one embodiment, obtaining the starting point of the forward difference portion includes the following steps: in the original route, along the direction of the original route, searching forward from the rear of the train for the difference portion from the new route; and taking the starting point of the difference portion as the starting point of the forward difference portion.

[0008] In one embodiment, the method further includes: if the original route and the new route are not in the same direction, then obtaining the stationary state of the train; if the train is stationary, then obtaining the current movement authorization state of the train; if the current movement authorization state of the train has been cleared, then releasing the route in front of the train head and obtaining the starting point of the backward difference portion; if the starting point of the backward difference portion is located behind the rear of the train tail, then releasing the route behind the starting point of the backward difference portion; splicing the new route portion with the starting point of the backward difference portion as the starting point and updating the movement authorization state; and sending the updated movement authorization state to the train.

[0009] In one embodiment, obtaining the starting point of the backward difference portion includes the following steps: in the original route, along the opposite direction of the original route, searching backward from the front of the train for the difference portion from the new route; and taking the starting point of the difference portion as the starting point of the backward difference portion.

[0010] In one embodiment, the method further includes: if the train is not stationary, the train maintains its original route; or, if the current movement authorization status of the train has not been cleared, the train maintains its original route; or, if the starting point of the backward difference portion is located in front of the rear of the train, the train maintains its original route.

[0011] In one embodiment, the method further includes: if the starting point of the forward difference portion is located behind the front of the train, the train maintains its original route; or, if an unreceived message is received from the train, the train maintains its original route.

[0012] In one embodiment, the accepted information includes: the movement authorization destination is accepted by the train and no emergency braking is triggered; or, the train ensures a stop.

[0013] In one embodiment, the method further includes: determining whether the original route maintained by the train has been released; if the original route has been released, implementing a new route and updating the movement authorization status; and sending the updated movement authorization status to the train. If the original route has not been released, then receiving the command for the new route from the train again.

[0014] In one embodiment, the mobility authorization status includes: mobility authorization direction, mobility authorization distance, mobility authorization endpoint, and device status.

[0015] This application also provides an electronic device, which includes: a processor; and a memory for storing processor-executable instructions; wherein the processor is configured to execute the above-described train route switching method.

[0016] The solution provided in the above embodiments of this application dynamically adjusts the train route switching operation by partially releasing, partially retaining, and partially splicing the trains according to the relationship between the original route and the new route. This simplifies the route switching operation process, preserves the protection and resources of the existing route to the maximum extent, and allows for immediate switching of different parts of the route under certain conditions to reduce switching delay, minimize the impact on trains, and improve operational efficiency.

[0033] Figure 2 This is a flowchart illustrating a train route switching method according to an embodiment of this application. Figure 2 As shown, the method includes the following steps S210-S270.

[0034] Step S210: Receive the command for the new train route.

[0035] During train route switching operations, the train travels on its original, predetermined route, which is the route before the route switch, referred to as the original route in this embodiment. When the electronic equipment receives a command for a new train route, it signifies the start of the train route switching operation, and the new route is the route after the train route switch.

[0036] Step S220: Obtain the original route of the train and the direction of the new route.

[0037] The original route and the new route may have the same or different directions, and the operation for switching train routes will also differ depending on the circumstances. Therefore, it is necessary to determine whether the original route and the new route have the same direction.

[0038] Step S230: If the original path and the new path are in the same direction, then obtain the starting point of the forward difference portion.

[0039] The specific method for obtaining the starting point of the forward difference portion is as follows: in the original route, along the direction of the original route, look forward from the rear of the train to find the difference portion from the new route, and take the starting point of the difference portion as the starting point of the forward difference portion.

[0040] The starting point of the forward difference portion is a key starting point for the train route switching operation in this embodiment. This starting point determines the position where the original train route and the new route are spliced ​​together. By splicing the routes, the train can be switched without stopping, thus preserving the protection and resources of the existing route to the maximum extent.

[0041] Step S240: If the starting point of the forward difference portion is located in front of the train head, then the starting point of the forward difference portion is sent to the train as the movement authorization endpoint.

[0042] After determining the location of the starting point of the forward difference portion, it is necessary to determine whether the starting point of the forward difference portion is in front of the train head. This is because if the starting point of the forward difference portion is already behind the train head, the train has already entered the turnout, and the train route switching operation in this embodiment cannot be performed. Therefore, if the starting point of the forward difference portion is behind the train head, the train will continue to maintain its original route.

[0043] Step S250: If the accepted information sent by the train is received, the path in front of the starting point of the forward difference portion is released.

[0044] After the train receives a new mobility authorization destination (i.e., the starting point of the forward difference portion), the train will determine whether the new mobility authorization destination is acceptable. If acceptable, the train will send an acceptance message to the electronic equipment; if unacceptable, the train will send a non-acceptance message to the electronic equipment. The electronic equipment will then receive either the acceptance message or the non-acceptance message.

[0045] Accepted information is categorized into two types: one is that the movement authorization destination has been accepted by the train and emergency braking has not been triggered; the other is that the train is guaranteed to stop. Unaccepted information is also categorized into two types: one is that the train will trigger emergency braking; the other is that the train cannot guarantee stopping.

[0046] Therefore, if an "accepted" message is received from the train, it indicates that the train route switching operation can proceed normally, and the electronic equipment will release the route ahead of the starting point of the forward difference portion. However, if an "unaccepted" message is received from the train, it indicates that the train route switching operation cannot proceed, and the train will continue to maintain its original route.

[0047] It is important to note that any unreleased original paths will be retained and used in subsequent path splicing steps.

[0048] Step S260: Piece the new path portion starting from the starting point of the forward difference portion, and update the movement authorization status.

[0049] Once the path preceding the starting point of the forward divergence portion of the original path is released, the electronic device immediately begins splicing the new path portion from the starting point of the forward divergence portion. At this time, the electronic device updates the movement authorization status based on the path formed by splicing the original path and the new path. The movement authorization status includes: movement authorization direction, movement authorization distance, movement authorization endpoint, and device status.

[0050] This method of splicing the original route with the new route allows for train route switching without stopping the train, preserving the protection and resources of the existing route to the maximum extent. At the same time, it allows for immediate switching of different parts of the route under certain conditions to reduce switching delays, minimize the impact on trains, and improve operational efficiency.

[0051] like Figure 3 This is a diagram illustrating how a train can switch routes to the other side of a turnout. Figure 3 When a train switches routes from the side of a turnout to the straight section, it can do so without stopping, provided that partial release and partial connection are met. While traveling on the original route, the train receives a command for a new route. Finding that the new and original routes are in the same direction, the train starts moving forward from the rear of the train along the original route, locating the point where the difference between the original and new routes begins (point P). Point P is then designated as the starting point of the forward difference, and since it is located in front of the train's front, it is sent to the train as the endpoint of the movement authorization. If the train sends an acceptance message, the route ahead of point P is released, i.e.,... Figure 3 The route C, indicated by the dashed line, is released. Subsequently, starting from point P, it will be concatenated with a portion of the new route; that is, a portion of the original route A will be concatenated with a portion of the new route B. The movement authorization status will then be updated based on the concatenated route.

[0052] Step S270: Send the updated mobility authorization status to the train.

[0053] After the mobile authorization status is updated, it needs to be sent to the train so that the train can know the current train route status after the splicing is completed.

[0054] Figure 4 This is a flowchart illustrating a train route switching method according to an embodiment of this application. Figure 4 As shown, the method includes the following steps S310-S380.

[0055] Step S310: Receive the command for the new train route.

[0056] This step is the same as step S210, and will not be repeated here.

[0057] Step S320: Obtain the original route of the train and the direction of the new route.

[0058] This step is the same as step S220, and will not be repeated here.

[0059] Step S330: If the original route and the new route are not in the same direction, then obtain the stationary state of the train.

[0060] During train route switching operations, if the original route and the new route have different directions, the train must be stationary before the route switching operation can be performed. Therefore, it is necessary to first obtain the train's stationary status to determine whether the train is truly stationary.

[0061] Step S340: If the train is stationary, obtain the current movement authorization status of the train.

[0062] The system determines whether a train is stationary by checking its stationary status. If it is stationary, the system retrieves the train's current movement authorization status. During train route switching operations, even if the train is stationary, if it still has a previous movement authorization status, the route switching operation cannot be performed. Therefore, it is also necessary to determine whether the train's current movement authorization status has been cleared.

[0063] If the train is not stationary, the train route switching operation cannot be performed, and the train will continue to maintain its original route.

[0064] Step S350: If the current movement authorization status of the train has been cleared, release the path in front of the train head and obtain the starting point of the backward difference portion.

[0065] By checking the current movement authorization status of the train, it is determined whether the train movement authorization status has been cleared. If it has been cleared, it means that the train route switching operation can be carried out. At this time, the route in front of the train head will be released immediately, and the starting point of the backward difference part will be obtained simultaneously.

[0066] The specific method for obtaining the starting point of the backward difference is as follows: in the original route, along the opposite direction of the original route, look for the difference between the train head and the new route, and take the starting point of the difference as the starting point of the backward difference.

[0067] The starting point of the backward difference portion is a key starting point in the train route switching operation in this embodiment. This starting point determines the position where the original train route and the new route are spliced ​​together. By splicing the routes together, the protection and resources of the existing routes can be preserved to the maximum extent during the train route switching operation.

[0068] If the train movement authorization status is not cleared, it means that the train route switching operation cannot be performed, and the train will continue to maintain the original route.

[0069] Step S360: If the starting point of the backward difference portion is located behind the rear of the train, then release the path behind the starting point of the backward difference portion.

[0070] After determining the location of the starting point of the rearward difference, it is necessary to determine whether the starting point of the rearward difference is behind the rear of the train. This is because if the starting point of the rearward difference is in front of the rear of the train, the train cannot switch from the original route to the new route. Therefore, if the starting point of the rearward difference is in front of the rear of the train, the train will continue to maintain the original route.

[0071] It is important to note that any unreleased original paths will be retained and used in subsequent path splicing steps.

[0072] Step S370: Piece the new path portion starting from the starting point of the backward difference portion, and update the movement authorization status.

[0073] Once the route in front of the train's engine is released, and the route behind the starting point of the rearward divergence portion of the original route is also released, the electronic equipment will immediately begin splicing the new route from the starting point of the rearward divergence portion. At this time, the electronic equipment will update the movement authorization status based on the route spliced ​​from the original route and the new route. The movement authorization status includes: movement authorization direction, movement authorization distance, movement authorization endpoint, and equipment status.

[0074] This method of splicing together the original route and the new route can preserve the protection and resources of the existing route to the greatest extent, while allowing for immediate switching of different parts of the route to reduce switching delays, minimize the impact on trains, and improve operational efficiency.

[0075] like Figure 5 This is a diagram illustrating a train switching its route to another direction and extending thereafter. Figure 5 After the train changes its route direction according to the route command, the new route can be arranged first, with some parts retained and some parts spliced ​​together. While the train is traveling on the original route, it receives the command for the new route. If it finds that the direction of the new route is inconsistent with the original route, it will determine whether the train is stationary and whether the current movement authorization status has been cleared. If both are true, then the route in front of the train's head will be released, meaning... Figure 5 The dashed line indicates that route D is released. Then, starting from the front of the train, the point where the difference between the original and new routes begins is located in the opposite direction of the original route, designated as point Q. At this point, point Q is taken as the starting point of the difference between the front and rear sections, and since point Q is located behind the rear of the train, the route behind point Q will also be released, meaning... Figure 5 The dashed line indicates that route G is released. Subsequently, starting from point Q, it will be concatenated with a portion of the new route; that is, a portion of the original route F will be concatenated with a portion of the new route E. The movement authorization status will then be updated based on the concatenated route.

[0076] Step S380: Send the updated mobility authorization status to the train.

[0077] After the mobile authorization status is updated, it needs to be sent to the train so that the train can know the current train route status after the splicing is completed.

[0078] Figure 6 This is a flowchart illustrating a train route switching method according to an embodiment of this application. In this embodiment, only the different parts between the old and new routes are switched according to the train status. The dynamic adjustment and optimization method includes three parts, as shown in Figure 6.

[0079] Part 1: Partial Release.

[0080] After receiving a new route command, the electronic device determines whether the new route is consistent with the original route direction.

[0081] If the new route direction is consistent with the original route direction, then along the original route and in its direction, locate the difference between the new route and the original route from the rear of the train, and obtain the starting point of the forward difference. Perform the following operations: Confirm the starting point of the forward difference. If it is in front of the train's front, inform the train of the move authorization endpoint at that point; if it is not in front of the train's front, maintain the original route. If the train's feedback indicates acceptance (i.e., the new move authorization is accepted and emergency braking is not triggered, or a stop guarantee is provided), immediately release the route in front of the starting point of the forward difference. If the train's feedback indicates non-acceptance (i.e., emergency braking may be triggered, or a stop cannot be guaranteed), maintain the original route.

[0082] If the new route direction is opposite to the original route direction, then the train is in a stationary state and a movement authorization state is obtained. If the train is stationary and the movement authorization has been cleared, the route in front of the train is immediately released; otherwise, the original route is maintained. At the same time, in the opposite direction of the original route, starting from the front of the train, the difference between the new route and the original route is searched, and the starting point of the backward difference is obtained. The following operations are performed: if the starting point of the backward difference is behind the rear of the train, the route behind the starting point of the backward difference is immediately released, and the new route is started from this point; if the starting point of the backward difference is not behind the rear of the train, the original route is maintained.

[0083] Part Two: Some Retentions

[0084] All portions of the original route that were not released will be retained.

[0085] Part Three: Partial Assembly.

[0086] Based on the portion of the original route that is retained, proceed as follows:

[0087] If the direction of the new route is the same as the direction of the existing route, and the route in front of the starting point of the forward difference section has been released, then the new route section will be spliced ​​immediately from the starting point of the forward difference section, and the movement authorization status (such as authorized direction, distance, equipment status, etc.) will be updated to the train.

[0088] If the direction of the new route is opposite to the direction of the existing route, the route ahead of the train has been released, and the route behind the starting point of the backward difference section has been released, then the new route section will be spliced ​​immediately from the starting point of the backward difference section, and the movement authorization status (such as authorized direction, distance, equipment status, etc.) will be updated to the train.

[0089] If, after the steps of the above embodiments, the train still maintains its original route during the shortcut switching operation, it is determined whether the original route maintained by the train has been released. If it is determined that the original route has been released, a new route is implemented, the mobility authorization status is updated, and the updated mobility authorization status is sent to the train. If it is determined that the original route has not been released, the command for the new train route is received again. At this time, the train route switching operation continues under the command for the new train route that is being received again, following the steps described in this embodiment.

[0090] Using the method of this embodiment, routes can be switched without stopping under certain conditions, and the route switching delay can be dynamically adjusted. For example, if only the route is switched from the turnout lateral direction to the turnout straight direction, the train can switch routes without stopping under the conditions of partial release and partial splicing; or after the route direction is changed according to the route command, the new route can be arranged first under the conditions of partial retention and partial splicing.
