Description

Technical Field

[0001] This invention relates to the field of rail transit signal control, and in particular to a fully automatic alternating turnaround method, equipment, and medium based on line resource management. Background Technology

[0002] Fully automated alternating turnaround is an operational organization method used in stations with two turnaround lines for alternating turnarounds. This method fully utilizes multiple turnaround lines. In traditional signaling systems, based on route operation and the first-in-first-out principle, trains enter and exit the turnaround lines in a cyclical rotation sequence according to the order of preceding and following trains to complete fully automated alternating turnarounds. However, in train control systems based on track resource management, since each train task request is a random event, it is highly prone to occurrences and problems. This can lead to discrepancies between the order in which subsequent trains enter the turnaround lines and the prescribed cyclical rotation sequence, resulting in operational disorder and even operational deadlock.

[0003] How to avoid the alternating turnaround disorder and operational chaos caused by multiple train missions running concurrently has become a technical problem that needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art by providing a fully automatic alternating turnaround method, equipment and medium based on line resource management.

[0005] The objective of this invention can be achieved through the following technical solutions: According to a first aspect of the present invention, a fully automatic alternating turnaround method based on line resource management is provided, the method comprising: Step S101: The dispatcher issues a fully automatic alternating turnaround command; Step S102: The resource manager executes the fully automatic alternating turnaround command and activates the fully automatic alternating turnaround mode; Step S103: The resource manager establishes the movable zone direction of the key switches at the entrance and exit of the fully automatic turnaround area; Step S104: The resource manager activates the exclusive control strategy for the turnout side defense zone corresponding to the fully automatic turnaround area; Step S105: The resource manager activates the disabling policy for the switch side protection zone corresponding to the fully automatic turnaround area.

[0006] Preferably, in step S101, the dispatcher's fully automatic alternating turnaround command specifically involves the dispatcher confirming the alternating turnaround task scheduling mode on the double turnaround line based on the operational situation, and issuing a fully automatic alternating turnaround command with the fully automatic alternating turnaround mode.

[0007] More preferably, the fully automatic alternating turnaround mode includes "alternating turnaround departure until side departure - side to straight departure" and "alternating turnaround departure until side departure".

[0008] More preferably, the difference between the “alternating turnaround departure until side departure - side to straight departure” and “alternating turnaround departure until side departure” modes lies in the different requirements for the order in which the train enters and exits the turnaround line, so that the train can alternately run to complete the turnaround. Wherein, “alternating turnaround departure” means that the train enters the turnaround line along the straight track and turns back along the lateral track, while “alternating turnaround departure” means that the train enters the turnaround line along the lateral track and turns back along the straight track.

[0009] Preferably, step S103 specifically involves the resource manager immediately activating the movable area of ​​the key turnout at the entrance of the fully automatic turnout area to face the turnout line, and immediately activating the movable area of ​​the key turnout at the exit of the fully automatic turnout area to face the direction away from the turnout line, based on the fully automatic alternating turnout mode.

[0010] Preferably, in step S104, the corresponding turnout is the positioning side defense zone of the key turnout adjacent to the up turnout line and the reverse side defense zone of the key turnout adjacent to the down turnout line.

[0011] More preferably, the exclusive control of the turnout side zone applies only to trains occupying the turnout side zone and the adjacent turnaround track.

[0012] Preferably, in step S104, when the resource manager receives the fully automatic alternating turnaround command, it immediately and automatically activates the exclusive control strategy for the turnout side defense zone corresponding to the fully automatic turnaround area.

[0013] Preferably, in step S105, under the "alternating turnaround departure until side departure - side to direct departure" mode, the corresponding turnout side protection zone prohibition strategy includes: a1) Avoid the operational task of subsequent trains applying to follow the train onto the up or down turnaround track; a2) Trains that avoid the current down-bound turnaround line depart before trains on the up-bound turnaround line.

[0014] More preferably, in the "alternating turnaround departure until side departure - side to direct departure" mode, the turnout side protection zone prohibition strategy automatically activates the corresponding turnout side protection zone prohibition state when at least one of the following conditions is met: b1) The down turnaround track is occupied by a train, and any subsequent train applying to follow the train into any turnout position along the down turnaround track is not in a single-lock state; b2) The up-line turnaround track is occupied by a train, and any turnout position along the route of the subsequent train is not in a single-lock state if the train applies to follow the train into the up-line turnaround track. b3) The up-line turnaround track is occupied by a train, and any turnout position that the train on the down-line turnaround track must pass through before the train on the up-line turnaround track is not in a single-lock state.

[0015] More preferably, in step S105, under the "side-to-direct departure - until side-departure alternating turnaround departure" mode, the corresponding turnout side protection zone prohibition strategy includes: a1) Avoid the operational task of subsequent trains applying to follow the train onto the up or down turnaround track; a2) Trains that avoid the current up-turn-off line depart before trains on the down-turn-off line.

[0016] More preferably, in the "side-to-direct departure - until side-departure alternating turnaround departure" mode, the turnout side protection zone prohibition strategy automatically activates the corresponding turnout side protection zone prohibition state when at least one of the following conditions is met: b1) The down turnaround track is occupied by a train, and any subsequent train applying to follow the train into any turnout position along the down turnaround track is not in a single-lock state; b2) The down turnaround track is occupied by a train, and any turnout position that the current up turnaround track train must pass through before the down turnaround track train departs is not in a single-lock state; b3) The up-line turnaround track is occupied by a train, and any subsequent train applying to follow the train into any turnout position along the up-line or down-line turnaround track is not in a single-lock state.

[0017] More preferably, the prohibition status of the turnout side defense zone only applies to prohibiting all operations that pass through the side defense zone other than the current turnout position, and prohibiting or deleting the reservation or sorting of these task-related trains in all areas from the turnout side defense zone to the task endpoint.

[0018] Preferably, the method is combined with a turnout single lock to release the prohibition of the side protection zone at the key turnout position for reversing, thereby realizing the fully automatic reversing function of a single reversing line.

[0019] Preferably, the fully automatic alternating turnaround method further includes a fully automatic alternating turnaround mode cancellation process, which includes: Step S201: The dispatcher issues a command to cancel fully automatic alternating turnaround; Step S202: The resource manager executes the command to cancel fully automatic alternating turnaround and deactivates the fully automatic alternating turnaround mode; Step S203: In the resource manager, cancel the turnout movable zone direction of the key turnouts at the entrance and exit of the fully automatic turnaround area respectively; Step S204: In the resource manager, the exclusive control strategy for the corresponding turnout side defense zone in the fully automatic turnaround area is canceled. Step S205: In the resource manager, cancel the disabling policy for the turnout side protection zone corresponding to the fully automatic turnaround area.

[0020] More preferably, step S201 specifically involves: the dispatcher confirming the cancellation of the current alternating turnaround task scheduling mode for the double turnaround line based on the operational situation, and the dispatcher issuing a command to cancel the fully automatic alternating turnaround.

[0022] 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.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention achieves fully automatic alternating turnaround based on resource management, which more effectively prevents the phenomenon of mismatch between the rotation sequence of multiple trains and the prescribed cycle during the alternating turnaround process.

[0024] 2. This invention effectively avoids side impacts, enhances the safety function of side impact protection, and also avoids operational deadlock.

[0028] 6.

Detailed Implementation

[0030] 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.

[0031] To meet the requirements of fully automatic alternating turnaround in rail transit systems, while avoiding operational disruptions caused by misaligned alternating turnaround sequences due to concurrent multi-train tasks, this invention provides a method that uses technical means to reasonably avoid misaligned alternating turnaround sequences. It also allows for online adjustment of the alternating turnaround mode and supports fully automatic turnaround on a single turnaround line when combined with a turnout single-lock function.

[0032] Alternating turnaround modes can be divided into two types: "alternating turnaround departure until side departure - side to direct departure" and "alternating turnaround departure until side departure." The sequence requirements for trains entering and exiting the turnaround track differ between these modes. Therefore, in a resource-management-based train control system, to cope with concurrent train operation tasks, it is necessary to rationally control track resources to meet the sequence requirements for trains entering and exiting the turnaround track under different modes.

[0033] This embodiment relates to a fully automated alternating turnaround method based on line resource management, the method comprising: Step S101: Based on the operation confirmation, the dispatcher issues a fully automatic alternating turnaround command with fully automatic alternating turnaround mode in the double turnaround line alternating turnaround task scheduling mode.

[0034] Step S102: The resource manager executes the fully automatic alternating turnaround command to activate the fully automatic alternating turnaround mode.

[0035] Step S103: The resource manager immediately activates the movable area of ​​the key turnout at the entrance of the fully automatic turnout area to face the turnout line, and immediately activates the movable area of ​​the key turnout at the exit of the fully automatic turnout area to face the direction away from the turnout line, according to the fully automatic alternating turnout mode. For example... Figure 3 As shown: Turnout No. 1 is the key turnout at the entrance of the fully automatic turnaround area, and its movable area is immediately activated as the "receiving direction"; Turnout No. 5 is the key turnout at the exit of the fully automatic turnaround area, and its movable area is immediately activated as the "departure direction". Operational tasks that avoid conflict with the turnaround direction are received and executed.

[0036] In step S104, the resource manager activates the exclusive control strategy for the relevant turnout side zone according to the corresponding fully automatic alternating turnaround mode. The turnout side zone prohibition strategy automatically activates the exclusive control state of the turnout side zone when the relevant conditions are met, and automatically cancels the exclusive control state when the conditions are not met. The exclusive control state of the turnout side zone only applies to trains occupying the turnout side zone and the adjacent turnaround track of that turnout, and does not affect all running tasks, reservations, sorting, or allocations at the current position of the turnout, nor does it affect trains currently running in that area. As shown in Figures 1 and 2: Once the resource manager receives the fully automatic alternating turnaround command, it immediately activates the exclusive control of the reverse side zone of turnout No. 3 (the key turnaround turnout adjacent to the down turnaround track) and immediately activates the exclusive control of the positioning side zone of turnout No. 7 (the key turnaround turnout adjacent to the up turnaround track) to prevent subsequent trains from following into the key turnaround turnout side zone, thus preventing trains on the turnaround track from being obstructed during the turnaround process and causing an operational deadlock.

[0037] In step S105, the resource manager activates the relevant turnout-side protection zone prohibition policy according to the corresponding fully automatic alternating turnaround mode to avoid subsequent trains unreasonably requesting resources within the fully automatic turnaround area and interfering with the turnaround sequence of the preceding trains. The turnout-side protection zone prohibition policy automatically activates the turnout-side protection zone prohibition state when the relevant conditions are met, and automatically cancels the turnout-side protection zone prohibition state when the conditions are not met. The turnout-side protection zone prohibition state only applies to prohibiting all running tasks passing through the side protection zone other than the current turnout position, and prohibiting or deleting the reservation or sorting of trains related to these tasks in all areas from the turnout-side protection zone to the task endpoint, without affecting all running tasks, reservations, sorting, or allocations at the current turnout position, and also without affecting trains currently running in this area.

[0038] If the fully automatic alternating turnaround mode selected by the dispatcher is "alternating turnaround departure until side departure - side to direct departure", then... Figure 4As shown, the first train first travels along line ① to the up platform, and the second train travels along line ② to the down platform. Then, the first train turns back along line ③ and departs, while the second train travels straight along line ④. That is, the first train's journey from side to side is: it travels along the straight track to the turnaround line, turns back along the side track, and departs. The second train's journey from side to straight is: it travels along the side track to the turnaround line, turns back along the straight track, and departs. The two trains alternate and complete the turnaround. The activation strategy for prohibiting turnout side zones is as follows: First, if the down-going turnaround track is occupied by a train and turnout 1 is in reverse, turnout 5 is in position, and turnout 7 is not in a single-lock state, then the turnout 1 reverse side zone prohibition is immediately activated to prevent subsequent trains from applying for the task of following the train into the down-going turnaround track at an unreasonable time. Second, if the up-going turnaround track is occupied by a train and turnout 1 is in position, turnout 5 is in reverse, and turnout 3 is not in a single-lock state, then the turnout 1 and 3 position side zone prohibitions are immediately activated. The turnout 1 position side zone prohibition is used to prevent subsequent trains from applying for the task of following the train into the up-going turnaround track at an unreasonable time, and the turnout 3 position side zone prohibition is used to prevent the train currently on the down-going turnaround track from departing before the train on the up-going turnaround track at an unreasonable time.

[0039] If the fully automatic alternating turnaround mode selected by the dispatcher is "side-to-direct departure - until side-to-alternating turnaround departure", then... Figure 5 As shown, the first train first travels along track ① to the down platform, and the second train travels straight along track ② to the up platform. Then, the first train travels straight along track ③ and the second train travels back along track ④ and travels out. That is, the first train travels from the side and departs directly, while the second train travels from the side. The two trains alternate and complete the turnaround. Activating the turnout side zone prohibition strategy: First, if the down turnaround track is occupied by a train and turnout 1 is in reverse position, turnout 5 is in position, and turnout 7 is not in a single-lock state, then the reverse side zone prohibition of turnout 1 and turnout 7 is immediately activated, and the reverse side zone exclusive use of turnout 3 (the turnaround turnout adjacent to the down line turnaround track) is immediately activated. The reverse side zone prohibition of turnout 1 is used to prevent subsequent trains from requesting to follow the train into the down turnaround track at an unreasonable time. First, the reverse side of turnout 7 is prohibited from being used to prevent trains on the upstream turnaround track from departing before trains on the downstream turnaround track at an unreasonable time. Second, if the upstream turnaround track is occupied by a train and turnout 1 is in position, turnout 5 is in reverse position, and turnout 3 is not in a single-lock state, then the position and reverse side of turnout 1 are immediately prohibited. The position side of turnout 1 is prohibited from being used to prevent subsequent trains from applying for the task of following trains onto the upstream turnaround track at an unreasonable time, and the reverse side of turnout 1 is prohibited from being used to prevent subsequent trains from applying for the task of following trains onto the downstream turnaround track at an unreasonable time.

[0040] The following descriptions will be divided into fully automatic alternating turnaround modes, and an example of the cancellation process of the fully automatic alternating turnaround mode based on line resource management will be given.

[0041] If the fully automatic alternating turnaround mode selected by the dispatcher is "alternating turnaround departure until side departure - side to direct departure", then... Figure 4 As shown, once the turnaround section is cleared, the side zone prohibition status is immediately and automatically lifted to ensure that subsequent trains continue to run in the order of cyclical rotation of turnaround track occupancy. If any one of the following turnouts—turnout 1 in position, turnout 5 in reverse position, or turnout 3—is given a single-lock command, the side zone prohibition for turnout 1 in position is immediately lifted to ensure that the up turnaround track has the function of performing fully automatic turnaround on a single turnaround track. Similarly, if any one of the following turnouts—turnout 1 in reverse position, turnout 5 in position, or turnout 7—is given a single-lock command, the side zone prohibition for turnout 1 in reverse position is immediately lifted to ensure that the down turnaround track has the function of performing fully automatic turnaround on a single turnaround track.

[0042] If the fully automatic alternating turnaround mode selected by the dispatcher is "side-to-direct departure - until side-to-alternating turnaround departure", then... Figure 5 As shown: Once the turnaround section is cleared, the side zone prohibition status is immediately and automatically lifted to ensure that subsequent trains continue to run in the order of cyclic rotation of turnaround occupancy. If any one of the following turnouts—turnout 1 in position, turnout 5 in reverse position, and turnout 3—is subject to a single-lock command, the side zone prohibition for turnout 1 in position is immediately lifted to ensure that the up turnaround line has the function of performing fully automatic turnaround on a single turnaround line. Similarly, if any one of the following turnouts—turnout 1 in reverse position, turnout 5 in position, and turnout 7—is subject to a single-lock command, the side zone prohibition for turnout 1 in reverse position is immediately lifted to ensure that the down turnaround line has the function of performing fully automatic turnaround on a single turnaround line.

[0043] Based on the dispatcher's scheduling strategy, key turnouts in the fully automatic turnaround area are individually locked, thereby enabling the fully automatic turnaround function of a single turnaround line in the event of a fault on a particular turnaround line. For example... Figure 3As shown: The prohibition of the turnaround key turnout position side protection zone is lifted by single-locking turnouts: Turnout No. 5 (the exit key turnout of the fully automatic turnout zone) is locked in the reverse position, or Turnout No. 1 (the entrance key turnout of the fully automatic turnout zone) is locked in the position, or Turnout No. 3 (the downline turnaround key turnout of the fully automatic turnout zone) is locked, thus prohibiting the completion of turnaround operations when the downline is faulty. Therefore, the resource manager will automatically lift the prohibition of the position side protection zone of Turnout No. 1 and the prohibition of the reverse side protection zone of Turnout No. 7 (the upline turnaround key turnout of the fully automatic turnout zone) to realize single-line fully automatic turnaround on the upline turnaround line. Similarly: If turnout No. 5 (the key exit turnout of the fully automatic turnout area) is locked in the position, or turnout No. 1 (the key entrance turnout of the fully automatic turnout area) is locked in the reverse position, or turnout No. 7 (the key turnout turnout of the up line in the fully automatic turnout area) is locked in the reverse position, the turnout operation will be prohibited when the up line fails. Therefore, the resource manager will automatically release the prohibition of the reverse side of turnout No. 1 and the prohibition of the position side of turnout No. 3 (the key turnout turnout of the down line in the fully automatic turnout area) to realize single-line fully automatic turnout on the down line.
