Train running direction control method, equipment and medium based on line resource management

Abstract

The present invention relates to a train direction control method, device, and medium based on line resource management. This method utilizes the directional enable of a section within a line resource to control all operational tasks passing through the current section. If the direction of an operational task does not match the direction set by the current section's directional enable, the task is prohibited from passing through the current section. Otherwise, upon meeting the set conditions, the directional enable is activated for the current section, allowing the train to automatically pass through the current section. Compared to existing technologies, this invention ensures that the operational process is not interfered with by oncoming train operations, thereby meeting the high-capacity operational requirements in various operational scenarios.

Description

Technical Field

[0001] The present invention relates to a rail transit signal system, and in particular to a train running direction control method, equipment and medium based on line resource management. Background Art

[0002] On heavily trafficked routes, urban rail transit systems must completely lock the bottleneck area leading from the depot to the mainline in the direction of exit before daily operations to ensure efficient train deployment from the depot to the mainline. During nighttime train closures, the entire area must be locked in the direction of entry. This tidal directional control effectively avoids temporary head-on collisions in bottleneck areas, improving train entry and exit efficiency.

[0003] In traditional signal systems, although automatic through-routes or section direction control can achieve unidirectional locking of line areas, ensuring that operations are not interfered with by oncoming trains, thereby meeting the high-capacity operation requirements under different operation scenarios, both methods are limited to controlling the operation direction within the area with fixed line configurations, and cannot dynamically set the area required for unidirectional operation according to operational needs. For example, in transition projects between existing and new lines, it is necessary to set the corresponding area as the control range for unidirectional operation according to the needs of different construction stages. In addition, the automatic through-routes require locking of the switches, which cannot meet the needs of multiple tracks running in a tidal manner in a single direction through the throat area. This cannot meet the operational scenarios of high-density exits and high-density entries in the throat area of ​​the vehicle depot in the morning and evening, and it is difficult to meet flexible operational needs.

[0004] After searching, Chinese patent publication number CN114275015A discloses a train control system and control method based on resource management, which specifically discloses fully exploiting existing station line resources, improving transportation capacity, avoiding head-on collisions, side collisions, derailment risks due to crossing switches, and other operational risks, significantly improving safety, meeting the needs of mixed operation of multi-mode trains, achieving seamless switching between different modes, ensuring system availability, and being suitable for multi-network integrated lines; it can effectively avoid operational deadlocks caused by concurrent operating tasks of multiple trains at the same switch, ensuring operational efficiency. However, this existing patent still cannot meet the high-capacity operation requirements under different operating scenarios. Therefore, how to ensure that the operation process will not be interfered with by oncoming train operations, and thus meet the high-capacity operation requirements under different operating scenarios, has become a technical problem that needs to be solved. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a train running direction control method, device and medium based on line resource management.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] According to the first aspect of the present invention, a train running direction control method based on line resource management is provided. The method uses the manual dynamic setting of the direction enable of the section in the line resources to control all operation tasks passing through the current section. If the direction of the operation task does not match the direction set by the current section direction enable, the operation task is prohibited from passing through the current section; otherwise, after the set conditions are met, the direction enable is activated for the current section, allowing the train to automatically pass through the current section.

[0008] As a preferred technical solution, the setting method of the direction enable includes: batch setting / cancelling all or specific sections in an area within the control range of the entire line, automatic setting / cancelling based on the operation plan, and manual setting / cancelling.

[0009] As a preferred technical solution, the setting conditions include:

[0010] If an operation task has been arranged for the train or a movement authorization has been established before the direction enable is set in the current section, and the direction of the operation task or movement authorization is inconsistent with the direction set by the direction enable, the direction enable will not be automatically activated for the current section until all movement authorizations and operation tasks in the current section that conflict with the direction set by the direction enable are released.

[0011] As a preferred technical solution, the setting conditions include:

[0012] If the current section has been set with direction enable and the direction is opposite to the direction enable before setting the direction enable, the direction enable will not be automatically activated for the current section until all operation tasks or movement authorizations in the current section that conflict with the direction enable are released and the direction enable for the current section is canceled.

[0013] As a preferred technical solution, the activation of the direction enable is performed through a trackside resource manager.

[0014] As an optimal technical solution, if the trackside resource manager receives an operation task request from ATS or the on-board controller, and the area covered by the current operation task intersects with the section enabled in the activation direction, if the passage conditions are met, the train is controlled to pass through the current section.

[0015] As an optimal technical solution, if it is determined that the current train operation task direction is consistent with the direction required by the section enable direction, the trackside resource manager will accept the operation task and sort the trains based on the order required by the operation plan, and control the trains to pass through the current section in sequence.

[0016] As a preferred technical solution, if it is determined that the current train operation task direction is inconsistent with the direction enabling direction activated in the section, the trackside resource manager prohibits the current train operation task from passing through the currently set direction enabling section.

[0017] As a preferred technical solution, after receiving the direction enable command of each section, the trackside resource manager checks the status and section type of the corresponding section.

[0018] As a preferred technical solution, if it is found that the current section is not in a conflicting state, the activation direction of the current section is enabled.

[0019] As a preferred technical solution, the conditions for determining whether the current section is in a conflict state are: if the direction of the operation task or movement authorization in the current section is inconsistent with the direction set by the direction enable, or the current section has been set with direction enable and the set direction is inconsistent with the direction required by the current direction enable to be set.

[0020] As a preferred technical solution, if the current section has been set to enable direction, once a train mission passes through the current section and is opposite to the direction set by the current section's direction enable, the train mission is prohibited from passing through the current section.

[0021] As a preferred technical solution, the dispatching system sends a direction enable command to the trackside resource manager for all sections in the selected area.

[0022] As a preferred technical solution, if the object of the direction enable setting is a non-branching section and the non-branching section is not in a conflicting state, the direction enable of the non-branching section is activated;

[0023] If the object of the direction enable setting is a switch section and the switch section is not in a conflicting state, the direction enable of the movable area and switch side defense area of ​​the current switch will be activated.

[0024] According to a second aspect of the present invention, an electronic device is provided, comprising a memory and a processor, wherein a computer program is stored in the memory, and the processor implements the method when executing the program.

[0025] According to a third aspect of the present invention, a computer-readable storage medium is provided, on which a computer program is stored, and when the program is executed by a processor, the method described above is implemented.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1) The present invention is based on tidal train operation direction enabling control, effectively ensuring that the operation process will not be disturbed by oncoming train operations, thereby meeting the high-capacity operation requirements in different operation scenarios;

[0028] 2) By controlling the train's operating direction, the present invention eliminates the need to lock switches or sections, thus enabling efficient flow control over the entire area.

[0029] 3) The present invention supports batch setting of multiple sections, which can meet flexible and dynamic settings manually or based on operation plans, and meet the operation needs in various operation scenarios;

[0030] 4) The present invention supports both non-switch sections and switch sections, and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 is a flow chart of the method of the present invention;

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0034] The present invention uses the direction enable of the section to control all operating tasks passing through the section. If the direction of the operating task is inconsistent with the direction set by the direction enable of the section, the operating task is prohibited from passing through the current section. If the current section has arranged an operating task or established a movement authorization for the train before the direction enable is set for the section, and the direction of the operating task or movement authorization is inconsistent with the direction set by the direction enable, it is necessary to wait until all movement authorizations and operating tasks in the section that conflict with the direction set by the direction enable are released before the direction enable is automatically activated for the section; if the current section has set the direction enable before the direction enable is set and the direction is opposite to it, it is necessary to wait until all operating tasks or movement authorizations in the section that conflict with the direction set by the direction enable are released, and the direction enable of the section is canceled before the direction enable is automatically activated for the section.

[0035] Regarding the setting method of direction enable: it supports batch setting of all sections within an area within the control range of the entire line, automatic setting based on the operation plan, and manual setting to meet the specific operation needs in different operation scenarios.

[0036] Once the trackside resource manager activates the direction enable for the section, if the trackside resource management receives an operation task application from ATS or the vehicle, and the area covered by the current operation task intersects with the section with the activated direction enable, and the current train operation task direction is consistent with the direction required by the section enable direction, then the trackside resource management will accept the operation task and sort the train based on the order required by the operation plan, and control the train to pass through the current section in sequence; conversely, if the current train operation task direction is inconsistent with the direction enable direction activated for the section, the trackside resource manager will prohibit the current train operation task from passing through the currently set direction enable section.

[0037] like Figure 1 As shown, the execution process of the method of the present invention is as follows:

[0038] Step 1: According to the operation plan or manual dispatch command, send a direction enable command for one or multiple sections in batches to the trackside resource manager;

[0039] Step 2: After receiving the direction enable command of each section, the trackside resource manager checks the status and section type of the sections in the area;

[0040] Step 3: If the check finds that the segments in the current area are not in a conflicting state, activate the direction enable for the current segment. The conditions for determining the conflicting state of the segment are: if the direction of the operation task or movement authorization in the current segment is inconsistent with the direction set by the direction enable, or if the current segment has been set with the direction enable and the set direction is inconsistent with the direction required by the current direction enable;

[0041] Step 4: If the current section has been set to enable direction, once a train task passes through the section and is opposite to the direction set by the section's direction enable, the train task is prohibited from passing through the current section.

[0042] like Figure 2 As shown, the direction enabling control process of the present invention is as follows:

[0043] 1. The dispatching system sends a direction enable command to the trackside resource manager for all sections in the selected area;

[0044] 2. After receiving the direction enable command of the section, the trackside resource manager checks the status of the section and checks the section type;

[0045] 3. If the direction enable is set for a non-fork section and the non-fork section is not in a conflicting state, activate the direction enable for the non-fork section;

[0046] If the object of the direction enable setting is a switch section and the switch section is not in a conflicting state, the direction enable of the movable area and switch side defense area of ​​the current switch will be activated.
