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] In the case of large passenger flow lines, before the official operation of urban rail transit every day, in order to ensure that trains can be deployed from the depot to the main line more efficiently, the throat area leading to the main line from the depot needs to be completely locked in the exit direction. When closing the train at night, the entire area needs to be locked in the entry direction. Through such tidal direction enabling control, temporary head-on conflict operation interference in the throat area can be effectively avoided, thereby improving the efficiency of train entry and exit.

[0003] In the traditional signal system, although the one-way locking of the line area can be achieved by automatically passing through the route or section direction control, ensuring that the operation is not disturbed by the operation of the oncoming train, thereby meeting the high-capacity operation requirements in different operation scenarios, both methods are limited to the operation direction control within the area of ​​the fixed configuration of the line, and it is impossible to dynamically set the area required for one-way operation according to the operation requirements. For example, in the transition project between the existing line and the new line, it is necessary to set the corresponding area as the control range of one-way operation according to the requirements of different construction stages. In addition, the automatic passing route requires locking the turnout, which cannot meet the requirements of tidal operation of multiple tracks in a single direction through the throat area. This can neither meet the operation scenarios of high-density exit and high-density entry in the throat area in the morning and evening in the depot, nor can it meet flexible operation requirements.

[0004] After searching, Chinese patent publication number CN114275015A discloses a train control system and control method based on resource management, which specifically discloses fully tapping 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 mixed operation of multiple modes of trains, achieving seamless switching between different modes, ensuring the availability of the system, and being suitable for lines with multi-network integration; it can effectively avoid operational deadlocks caused by concurrent operating tasks of multiple trains at the same switch, and ensure operational efficiency. However, the 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 the operation of oncoming trains, and then 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 method for controlling the direction of train operation based on line resource management is provided. The method uses the direction enable of the section in the line resources to be manually and dynamically set 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 direction enable of the current section, 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 to allow 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 operating 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 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 current section that conflict with the direction set by the direction enable are released before the direction enable is automatically activated for the current section.

[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 it before setting the direction enable, it is necessary to wait until all operation tasks or movement authorizations in the current section that conflict with the direction set by the direction enable are released and the direction enable of the current section is canceled before the direction enable is automatically activated for the current section.

[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 the ATS or the on-board controller, and the area covered by the current operation task intersects with the section enabled by the activation direction, if the passage conditions are met, the train is controlled to pass through the current section.

[0015] As a preferred 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 condition for determining whether the current section is in a conflict state is as follows: 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 with direction enable, 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-forking section and the non-forking section is not in a conflicting state, the direction enable of the non-forking section is activated;

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

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

[0025] According to a third aspect of the present invention, there is provided a computer-readable storage medium having a computer program stored thereon, wherein the program implements the method described above when executed by a processor.

[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, which effectively ensures that the operation process will not be disturbed by the operation of oncoming trains, thereby meeting the high-capacity operation requirements in different operation scenarios;

[0028] 2) The present invention supports efficient flow control over the entire area by enabling the train operation direction without locking the turnout or the section;

[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 non-switch sections and switch sections and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0034] The present invention utilizes the direction enable of the section to control all operation tasks passing through the section. If the direction of the operation task does not match the direction set by the direction enable of the section, the operation task is prohibited from passing through the current section. If the current section has arranged an operation task or established a movement authorization for the train before the direction enable is set for the section, and the direction of the operation task or movement authorization is inconsistent with the direction set by the direction enable, it is necessary to wait until all movement authorizations and operation 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 operation 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 cancelled 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 in an area within the control range of the entire line, automatic setting based on the operation plan, and manual setting to meet 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 by 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 segment in the current area is not in a conflict state, activate the direction enable for the current segment. The conditions for determining the conflict 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 to be set;

[0041] Step 4: If the current section has been set with direction enable, once a train task passes through the section and is opposite to the direction set by the section 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 comprises the following steps:

[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 object of the direction enable setting is a non-fork section and the non-fork section is not in a conflict state, activate the direction enable of the non-fork section;

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