Description

Technical Field

[0001] This invention relates to the field of rail transit signal control, and in particular to a turnout single-lock method, device and medium based on line resource management. Background Technology

[0002] In traditional signaling systems, once a turnout is locked in its current position, routes passing through the same position can be arranged. Simultaneously, a turnout under route locking can also be individually locked; turnout locking / unlocking is independent of route locking / unlocking. However, in resource-management-based systems, performing the same single-locking function may conflict with the prioritization of turnout area resources required for existing train operation paths, potentially leading to operational deadlock. For example, if a turnout is currently in its designated position, and the track resources for that turnout are being used by the preceding train, while another train (the following train) needs to pass through the reverse position of the turnout, and the track resources in the reverse position and downstream of the turnout have already been reserved for the following train and are listed as the second position in the priority list, once the turnout is locked in its designated position, if no intervention is taken for other subsequent trains (those that need to pass through the current turnout's reverse position) since the track resources related to the turnout have already been reserved and are listed in the priority list, then after the preceding train leaves the track resources of the turnout's designated position and completes its subsequent task, the turnout cannot be switched to the reverse position required by the subsequent train because it is locked in its designated position. The track resources in the reverse position of the turnout, as well as all the track resources reserved for the original following train within the scope of the subsequent train's task downstream of the turnout, cannot be released, and therefore cannot be allocated to other trains that need the track resources of the turnout's designated position. Ultimately, this leads to an operational deadlock caused by multiple trains expecting other trains to release the track resources in the current turnout area.

[0003] The technical problem that needs to be solved is how to achieve both the function of single-lock turnout and avoid operational deadlock caused by single-lock turnout. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art by providing a turnout single-lock method, device and medium based on line resource management.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] According to a first aspect of the present invention, a turnout single-lock method based on track resource management is provided, the method comprising:

[0007] Step S101: The dispatcher issues a turnout single-lock command to the resource manager;

[0008] Step S102: The resource manager receives the turnout single lock command and executes the turnout single lock.

[0009] Step S103: Based on the current switch position, the resource manager automatically activates the side zone prohibition state of the other switch position, and proceeds to step S104.

[0010] Step S104: Determine whether the current train operation task passes through a side defense zone that is in a prohibited state. If yes, proceed to step S105; otherwise, proceed to step S106.

[0011] Step S105: Delete the train ID from the resource reservation and sorting lists of all areas from the next section of the guaranteed stopping point to the end point of the current train operation task.

[0012] Step S106: Determine whether the current turnout position is consistent with the running direction of the subsequent train. If yes, it will have no impact on train operation; otherwise, proceed to step S107.

[0013] In step S107, the resource manager refuses to reserve, sort, and allocate resources for subsequent trains.

[0014] Preferably, in step S101, the dispatcher issuing a turnout single-lock command to the resource manager specifically involves: the dispatcher confirming the tasks of all trains that need to pass through single-locked turnouts based on the operation and turnout status, then confirming the train task scheduling strategy, and issuing the turnout single-lock command to the resource manager.

[0015] Preferably, in step S103, the turnout position includes both the initial and reverse positions.

[0016] Preferably, in step S103, automatically activating the side protection zone prohibition state of the other position of the turnout specifically means: if the current turnout position is reversed, then automatically activate the positioning side protection zone prohibition state; otherwise, automatically activate the reverse side protection zone prohibition state.

[0017] Preferably, in step S103, once the turnout is activated to a single-lock state, the other side of the current turnout is automatically activated to a prohibited state.

[0018] Preferably, in step S103, executing the turnout single lock further includes: if the current turnout is in a lost-indication state, the resource manager will automatically activate and disable all side zones of the turnout until the turnout single lock state is canceled, wherein the lost-indication state is the state in which the turnout cannot be detected.

[0019] Preferably, in step S107, the resource manager's refusal to reserve, sort, and allocate resources for subsequent trains specifically means that after a turnout is locked, if a train applies for a running task to pass through the other side of the turnout's control zone, the resource manager refuses to reserve, sort, and allocate all upstream and downstream line resources associated with the other side of the turnout's control zone until the turnout's lock and the prohibition status of the other side of the turnout's control zone are lifted.

[0020] Preferably, the method further includes a single-lock release process, which includes:

[0021] Step S201: The dispatcher issues a turnout release single-lock command to the resource manager;

[0022] Step S202: The resource manager performs the operation to release the turnout single lock, and the turnout is automatically released from the single lock state;

[0023] In step S203, the resource manager simultaneously and automatically removes the prohibition status of the other side zone of the current turnout.

[0024] More preferably, in step S201, the dispatcher issuing the turnout release single-lock command to the resource manager specifically involves the dispatcher confirming the current task of all trains passing through turnouts that require single-lock release based on the operational situation and turnout status, and issuing the turnout release single-lock command to the resource manager.

[0025] More preferably, in step S203, automatically releasing the prohibition state of the other position side of the current turnout specifically means: if the current turnout is in position, the prohibition of the turnout reverse side side is automatically released; otherwise, the prohibition of the turnout position side side is automatically released.

[0026] According to a second aspect of the present invention, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the program to implement the method described thereon.

[0027] According to a third aspect of the present invention, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method described thereon.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention provides a turnout single-lock method based on track resource management, which can effectively prevent operational deadlock when multiple trains converge or diverge at a turnout.

[0030] 2. This invention provides a more flexible scheduling method for operations.

[0031] 3. This invention effectively avoids side impacts and achieves the safety function of side impact protection.

[0032] 4. The present invention provides a turnout single-lock release method based on line resource management, which releases turnouts in a single-lock state and turnout side protection zones in a prohibited state, freeing up resources for subsequent operations and improving resource utilization. Attached Figure Description

[0033] Figure 1 This is a schematic diagram of the turnout single lock activity in this invention;

[0034] Figure 2 This is a schematic diagram of the turnout unlocking single-lock activity in this invention. Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0036] This embodiment relates to a turnout single-lock method based on track resource management.

[0037] like Figure 1 The diagram shown is an activity diagram of a turnout single lock based on track resource management, including:

[0038] In step S101, the dispatcher confirms the tasks of all trains that need to pass through single-locked switches based on the operation and switch status, then confirms the train task scheduling strategy and issues a single-lock command to the resource manager for the switch.

[0039] In step S102, the resource manager receives the turnout single lock command, executes the turnout single lock, and immediately activates the turnout single lock status.

[0040] In step S103, the resource manager automatically activates the side zone prohibition state of the other position of the turnout according to the current turnout position, and proceeds to step S104; if the current turnout position is not in the reverse (fixed) position, the "prohibited" state of the turnout reverse (fixed) position side zone is activated; if the current turnout is in the lost indication state, all side zones of the turnout are automatically activated and prohibited until the turnout single lock state is canceled.

[0041] Step S104: Determine whether the current train operation task passes through a side defense zone that is in a prohibited state. If yes, proceed to step S105; otherwise, proceed to step S106.

[0042] Step S105: Assuming the current position of the turnout is fixed, before the turnout is locked, if a train has received a running task that passes through the turnout's reverse side defense zone (the turnout's reverse side defense zone activated by the single lock), and the resource manager has created reservations or sorted the line resources involved in the task for the train that passes through the turnout's reverse side defense zone, and the current train's guaranteed stopping point projection does not intersect with the area from the turnout's side defense zone to the task endpoint, and the current position of the turnout is inconsistent with the train's task, once the turnout is activated to a single lock state (the single lock is fixed at the current position), the current turnout's reverse side defense zone will automatically activate a prohibited state, and will automatically cancel the reservation of all line resources from the next section of the guaranteed stopping point to the task endpoint for the current train, and delete the current train ID from the sorted list of each area of ​​these line resources;

[0043] Step S106: Determine whether the current turnout position is consistent with the train's running direction. If the current turnout position is in the reverse (fixed) position, it has no effect on the train's running direction when the turnout is in the reverse (fixed) position. Otherwise, proceed to step S107.

[0044] Step S107: Assuming the current turnout is in position, after the turnout is locked, if a train requests a running task to pass through the turnout's reverse side defense zone (the side defense zone activated by the lock), then all upstream and downstream line resources associated with the turnout's reverse side defense zone will be refused to be reserved, sorted, and allocated to these trains because the reverse side defense zone of this key turnout is in a prohibited state, until the turnout's lock is released and the prohibited state of the area is lifted.

[0045] The side zone prohibition state only prohibits all operating tasks that pass through the side zone of the current turnout (the side zone activated by the single lock), without affecting all operating tasks, reservations, sequencing or allocations at the current position of the current turnout, and also without affecting trains running in that area.

[0046] This embodiment also relates to a method for releasing a single lock on a turnout based on track resource management.

[0047] like Figure 2 The diagram shown is an activity diagram for releasing a single lock on a turnout based on track resource management. Specifically, it includes:

[0048] S201, based on the operational situation and turnout status, the dispatcher confirms the current task of issuing a turnout release command to the resource manager for all trains passing through turnouts that require single-locking.

[0049] S202, the resource manager performs the operation to release the turnout single lock, and the turnout is automatically released from the single lock state.

[0050] S203, the resource manager will also automatically lift the prohibition status of the other position side of the current turnout. If the current turnout is in position, the prohibition of the turnout reverse side side will be automatically lifted; otherwise, the prohibition of the turnout position side side will be automatically lifted.

[0051] The dispatcher then reorganized the operation of the turnouts after the single-lock was released, based on the operational activities.
