Description

Technical Field

[0001] The present application relates to the field of rail transit, and particularly to a method, a system, an electronic device, and a storage medium for line resource authorization. Background Art

[0002] With the rapid development of technology, rail transit has developed rapidly. Due to the characteristics of convenience and speed, rail transit has become the travel choice of many passengers. As a result, the operation pressure of rail transit has become increasingly severe. To relieve the operation pressure, an operation mode using virtual formation technology to improve the operation efficiency has been proposed, which can greatly shorten the operation interval.

[0003] When a new generation of train control system based on vehicle-to-vehicle communication is in operation, a train needs to apply to the object controller OC for the resources of the front line. The object controller OC allocates resources according to the resource occupancy situation. After the train obtains the resources of the front line, the train can enter the resources of the front line.

[0004] In the traditional virtual formation implementation scheme, in order to enable virtual formation trains to run with a small following distance, the trailing train needs to obtain the line resources beyond the rear of the leading train. This requires the resource management system to allocate the line resources that the leading train is using and the line resources that have been allocated to the leading train to the trailing train at the same time. This allocation method will cause compatibility problems between the virtual formation train system and the object controller OC that has not been specifically modified for virtual formation trains. In addition, in a system that can only manage single-vehicle resources, the resource management system cannot allocate the resources that have been allocated to one train and the resources that it is using to another train, because this violates the basic safety principle of the single-vehicle resource management system, that is, only idle and unallocated resources can be allocated to trains. Summary of the Invention

[0005] To solve one of the above technical defects, the embodiments of the present application provide a method, a system, an electronic device, and a storage medium for line resource authorization.

[0006] According to the first aspect of the embodiments of the present application, a method for line resource authorization is provided. The method is applied to a virtual formation train with a single-vehicle resource management function, and the method includes:

[0007] The trailing train sends a line resource application between the front of the trailing train and the rear of the leading train to the object controller OC, and receives the line resources of the trailing train allocated by the object controller OC according to the line resource application of the trailing train;

[0008] The leading train sends a line resource application in front of the front of the leading train to the object controller OC, and receives the line resources of the leading train allocated by the object controller OC according to the line resource application of the leading train;

[0009] The leading vehicle sends the line resource of the leading vehicle to the trailing vehicle;

[0010] The trailing vehicle fuses the line resource of the trailing vehicle and the line resource of the leading vehicle to generate a line resource authorization for the trailing vehicle;

[0011] Control the operation of the trailing vehicle according to the line resource authorization.

[0012] According to the second aspect of the embodiments of the present application, a line resource authorization system is provided. The system is applied to a virtual formation train with a single vehicle resource management function. The system includes:

[0014] A line resource authorization fusion unit, configured to fuse the line resource of the trailing vehicle and the line resource of the leading vehicle to generate a line resource authorization after the leading vehicle sends the line resource of the leading vehicle to the trailing vehicle;

[0015] A control unit, configured to control the operation of the virtual formation train according to the line resource authorization.

[0016] According to the third aspect of the embodiments of the present application, an electronic device is provided, including:

[0017] A memory, configured to store a computer program;

[0018] A processor, configured to implement the line resource authorization method as described above when executing the computer program.

The computer-readable storage medium stores computer-executable instructions, and when the computer-executable instructions are loaded and executed by a processor, the line resource authorization method as described above is implemented.

[0020] By adopting the line resource authorization method provided in the embodiments of the present application, the object controller OC only needs to send the line resources applied by the front and rear vehicles correspondingly, without making special or targeted modifications to the object controller OC, avoiding the problem of compatibility defects of the object controller OC in the traditional line resource authorization method.

[0028] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further details the exemplary embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0029] Embodiment 1

[0030] As Figure 1 , this embodiment proposes a method for authorizing line resources, and the method includes:

[0031] S101. The following vehicle sends a line resource application between the head of the following vehicle and the tail of the preceding vehicle to the object controller OC, and receives the line resources of the following vehicle allocated by the object controller OC according to the line resource application of the following vehicle.

[0032] Specifically, the virtual formation train described in this embodiment only has the function of single - vehicle resource management. Since the formation of the virtual formation train begins, the following vehicle starts to shorten the tracking distance with the leading vehicle. Generally speaking, for a virtual formation train with the function of formation resource management, the following vehicle applies to the object controller OC for the line resources of the section where the leading vehicle is located and a certain distance in front of the leading vehicle. Correspondingly, the object controller OC allocates the line resources of the line where the leading vehicle is located and a certain distance in front of the leading vehicle to the following vehicle. This will cause the compatibility problem between the virtual formation train and the object controller OC as described above. In this application, the following vehicle of the virtual formation train with only the single - vehicle resource management function applies to the object controller OC for the line resources between the rear of the leading vehicle and the front of the following vehicle. Correspondingly, the object controller OC will allocate the line resources behind the leading vehicle to the following vehicle, as Figure 2 shown. In this way, it can ensure that the basic safety principle of the single - vehicle resource management system is followed, that is, the idle and unallocated line resources behind the leading vehicle are allocated to the following vehicle to ensure the safe operation of the train.

[0033] S102. The leading vehicle sends an application for the line resources in front of the leading vehicle head to the object controller OC, and receives the line resources of the leading vehicle allocated by the object controller OC according to the line resource application of the leading vehicle;

[0034] S103. The leading vehicle sends the line resources of the leading vehicle to the following vehicle.

[0035] Specifically, in this embodiment, the leading vehicle applies to the object controller OC for line resources. Correspondingly, the object controller OC will allocate the line resources at a certain distance in front of the leading vehicle to the leading vehicle. The leading vehicle controls its own operation according to the line resources allocated by the object controller OC. At the same time, after the leading vehicle obtains the line resources of the leading vehicle allocated by the object controller OC, it sends the line resources of the leading vehicle to the following vehicle, as Figure 3 shown.

[0036] S104. The following vehicle fuses the line resources of the following vehicle and the line resources of the leading vehicle to generate the line resource authorization of the following vehicle.

[0037] Specifically, in this embodiment, the following vehicle obtains the end point of the line resources of the following vehicle through the line resources of the following vehicle, and obtains the start point and the end point of the line resources of the leading vehicle through the line resources of the leading vehicle. By identifying the relative position relationship between the end point of the line resources of the following vehicle and the start point of the line resources of the leading vehicle, and generating the line resource authorization according to the relative position relationship. This embodiment effectively fuses the line resources of the leading vehicle and the line resources of the following vehicle. The following vehicle uses the line resources of the leading vehicle to generate the line resource authorization, so that the virtual formation train that only supports the single - vehicle resource management function can also achieve the purpose of running with a smaller tracking distance.

[0038] More specifically, first, it is determined whether the end point of the rear vehicle's line resource coincides with the start point of the front vehicle's line resource. When the end point of the rear vehicle's line resource coincides with the start point of the front vehicle's line resource, the line resource between the start point of the rear vehicle's line resource and the end point of the front vehicle's line resource is used as the line resource authorization, as Figure 4 shown. In this embodiment, the line resource between the start point of the rear vehicle's line resource and the end point of the front vehicle's line resource is used as the line resource authorization to enable the front and rear vehicles of the virtual formation train to run with a smaller tracking distance.

[0039] During the actual operation of the train, due to the influence of the track environment or line environment, communication failures or interferences such as communication delays may occur, which may cause the end point of the rear vehicle's line resource to be possibly in front of the start point of the front vehicle's line resource. In view of this, in this embodiment, when the end point of the rear vehicle's line resource does not coincide with the start point of the front vehicle's line resource, it is continuously determined whether the end point of the rear vehicle's line resource crosses the start point of the front vehicle's line resource. And when the end point of the rear vehicle's line resource crosses the start point of the front vehicle's line resource, that is, when the end point of the rear vehicle's line resource is in front of the start point of the front vehicle's line resource, the line resource between the start point of the rear vehicle's line resource and the end point of the front vehicle's line resource is also used as the line resource authorization. This can reduce the deviation of line resource authorization caused by communication failures or interferences.

[0040] In addition, when the end point of the rear vehicle's line resource does not cross the start point of the front vehicle's line resource, that is, when the end point of the rear vehicle's line resource is behind the start point of the front vehicle's line resource, the rear vehicle's line resource is used as the line resource authorization. When the end point of the rear vehicle's line resource is behind the start point of the front vehicle's line resource, it indicates that there may be abnormalities in the track line conditions or communication abnormalities. In this case, there will be an unallocated line resource area between the front vehicle and the rear vehicle, and at this time, the integration of the front vehicle's line resource and the rear vehicle's line resource cannot be carried out to ensure the operation safety of the virtual formation train. The rear vehicle can only use the rear vehicle's line resource obtained by the rear vehicle before as the line resource authorization at this time.

[0041] During the operation of the virtual formation train, the situation of decoupling may occur at any time, including the situation of exiting the formation due to abnormalities or normal decoupling. In this embodiment, during the operation of the virtual formation train, the formation state during the operation is obtained in real time so as to change the strategy for controlling the train operation in time when the formation state changes to ensure the train operation safety. When the virtual formation train is decoupled during the operation, the rear vehicle first cancels the line resource authorization during normal formation, that is, the line resource authorization generated after the integration of the rear vehicle's line resource and the front vehicle's line resource. At the same time, due to the decoupling of the virtual formation train, the communication between the front vehicle and the rear vehicle is also cut off. The front vehicle's front vehicle line resource cannot be sent to the rear vehicle. The rear vehicle re-sends a line resource application between the rear vehicle's head and the front vehicle's tail to the object controller OC and receives the rear vehicle's line resource allocated by the object controller OC according to the rear vehicle's line resource application, as Figure 5As shown in the figure. Finally, the re-obtained rear vehicle line resources are used as line resources to authorize and control the operation of the rear vehicle.

[0042] S105. Control the operation of the rear vehicle according to the line resource authorization.

[0043] Specifically, as described above, when the end point of the rear vehicle line resource is the start point of the front vehicle line resource, or the end point of the rear vehicle line resource is in front of the start point of the front vehicle line resource, the front vehicle line resource and the rear vehicle line resource are fused. The line resource between the start point of the rear vehicle line resource and the end point of the front vehicle line resource is used as the line resource authorization, and the operation of the rear vehicle of the virtual formation train is controlled according to the fused line resource authorization. When the end point of the rear vehicle line resource is behind the start point of the front vehicle line resource, the rear vehicle line resource is used as the line resource authorization, and the operation of the rear vehicle of the virtual formation train is controlled by this rear vehicle line resource. When the virtual formation train is disassembled, the disassembled front vehicle and rear vehicle respectively control the operation of the front vehicle and the rear vehicle according to the front vehicle line resource and the rear vehicle line resource previously allocated by the object controller OC.
