Description

Technical Field

[0001] The present invention relates to a rail transit signal system, and in particular to a rail transit multi-line mixed operation train path control system and method. Background Art

[0002] Currently, urban rail transit has achieved networked operation, resulting in a surge in passenger traffic and increased capacity demand on backbone lines in urban core areas, leading to a growing demand for multi-line mixed operations. In multi-line mixed operations, some trains are dedicated to fixed lines. Due to inconsistencies in vehicle type, platform width, and length, they can only access platforms on shared lines and dedicated lines and cannot enter areas on other lines. Other trains are shared trains, capable of operating on shared lines and on different lines. Existing rail transit signal control systems use routes to allocate operating path resources to trains. When route errors are triggered, manual confirmation is required, relying solely on the driver observing the status of the signal ahead and the dispatcher observing the status of line equipment. The signal control system is unable to correct errors in real time.

[0003] After searching, Chinese patent publication number CN117755361A discloses a method, equipment and medium for managing line resources in rail transit operations. Specifically, it discloses that the method is achieved by grouping and laying out line resources in the turnout area and establishing a safe direction for trains using line resources. The method includes: step S1, grouping and laying out line resources in the turnout area; step S2, establishing a safe direction for trains using line resources; step S3, determining the status of line resources in use and allocating line resources; step S4, releasing resources and resetting the safe direction of line resources. However, this existing patent does not involve train control in a multi-line mixed operation scenario. Therefore, how to control trains of different models to run along designated paths in a multi-line mixed operation scenario and prevent trains from entering unexpected platform areas has become a technical problem that needs to be solved. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a rail transit multi-line mixed operation train path control system and method.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] According to a first aspect of the present invention, a rail transit multi-line mixed operation train path control system is provided, the system being connected to a train controller, the system comprising a train and platform mapping module, a train operation main control module, and an on-board interface server module connected in sequence, the on-board interface server module being connected to the train controller;

[0007] The train and platform mapping module automatically generates a train-to-line mapping relationship and a platform-to-line mapping relationship based on system data;

[0008] The train operation main control module performs single-step train operation, head car and planned car control, and verifies the consistency of the train operation path and platform;

[0009] The on-board interface server module verifies the validity of the train operation path based on the received train operation task and sends it to the train controller to control the train to run according to the specified path in real time; at the same time, it receives train positioning information from the train controller and monitors the train operation path in real time. When the predicted train operation path is inconsistent with the expected one, it actively sends a functional speed limit immediate stop instruction to the train controller to correct the train operation path in real time.

[0010] As a preferred technical solution, the specific generation process of the train-to-line mapping relationship and the platform-to-line mapping relationship is as follows:

[0011] Read the train number information and train line information in the system database and generate a train and line mapping list;

[0012] Read the platform number information and the line information to which the platform belongs from the system database, and generate a platform and line mapping list.

[0013] As a preferred technical solution, the train operation main control module performs single-step operation of the train as follows:

[0014] A single-step operation task is set for the train. The train runs from the starting platform to the next adjacent platform, and the consistency of the starting platform and the terminal platform with the train line attributes is verified. If the starting platform and the terminal platform pass the verification, the train single-step operation task is sent to the on-board interface server module, including the starting platform, the terminal platform and the switch position in the path of the task. If the starting platform and the terminal platform fail to be verified, the train single-step operation task is rejected from being sent to the on-board interface server module.

[0015] As a preferred technical solution, the train operation main control module performs the following control on the head car:

[0016] A head car task is set for the train, and the train runs according to a preset single loop path. The consistency of all platforms in the train running path with the train line attributes is verified. If the verification passes, the train running task is sent to the on-board interface server module in the order of platforms, including the starting platform of the task, the next arrival platform and the switch position in the path. When the train arrives at the next platform, the next running task is sent. Only one running task is sent at a time. When the train arrives at the destination, the train running task is cleared.

[0017] As a preferred technical solution, the train operation main control module performs planned train control specifically as follows:

[0018] Set a planned train task for the train. The train runs according to the preset planned route and automatically executes the next loop path after reaching the destination, realizing round-trip operation after connecting multiple loops.

[0019] As a preferred technical solution, the train operation master control module performs dispatch planning management for the planned trains, specifically:

[0020] Prepare dispatch plans, assign schedules to trains, and verify the consistency of the mapping relationship between trains and schedules.

[0021] As a preferred technical solution, if the train is a shared train and passes the verification, it will be directly matched to the schedule;

[0022] If the train is a single-line dedicated train, check whether the line attributes of the starting platform, destination terminal platform, and all intermediate platforms on the running path of each Loop in the schedule allocated to the train are consistent with the train line attributes or are co-line platforms. If any of them are inconsistent, the matching fails and the schedule is not allowed to be allocated to the train; if the schedule is matched successfully, the train operation task is sent to the on-board interface server module according to the platform order and arrival and departure times in the Loop. When the train arrives at the next platform, the next operation task is sent again, and only one operation task is sent at a time.

[0023] As an optimal technical solution, when the on-board interface server module receives a train operation task, it verifies the consistency between the train identification attribute in the train operation command and the line attributes of the starting platform and the next station platform in the operation command. If they are consistent, it is sent to the train controller; if they are inconsistent, the train operation command is refused to be sent.

[0024] As an optimal technical solution, after receiving the train location from the train controller, the on-board interface server module verifies the consistency between the line attributes of the next arrival platform and the train line attributes. If they are inconsistent, the train is prohibited from departing from the platform. If the train is a skip-stop train or has already departed from the platform, a functional speed limit immediate stop command is sent to the train to prevent the train from entering other unexpected areas. If the verification passes, the train is controlled to run according to the planned time.

[0025] As an optimal technical solution, after the on-board interface server module receives the train positioning from the on-board controller, when the train approaches the switch trigger rail, it verifies the consistency between the switch position ahead and the train running path. If the switch position verification fails, the train is prohibited from continuing to run, and a functional speed limit immediate stop command is sent to the train to prevent the train from continuing to run along the wrong switch position and entering other unexpected areas. If the verification passes, the train is controlled to run according to the planned time.

[0026] According to a second aspect of the present invention, a method for controlling a train path in a multi-line mixed operation rail transit system is provided, the method comprising:

[0027] The train and platform mapping module automatically generates a train-to-line mapping relationship and a platform-to-line mapping relationship based on system data;

[0028] The train operation main control module performs single-step train operation, head car and planned car control, and verifies the consistency of the train operation path and platform;

[0029] The on-board interface server module verifies the validity of the train operation path based on the received train operation task and sends it to the train controller to control the train to run according to the specified path in real time; at the same time, it receives train positioning information from the train controller and monitors the train operation path in real time. When the predicted train operation path is inconsistent with the expected one, it actively sends a functional speed limit immediate stop instruction to the train controller to correct the train operation path in real time.

[0030] According to a third 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.

[0031] According to a fourth 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.

[0032] Compared with the prior art, the present invention has the following advantages:

[0033] 1) The present invention designs a dual-redundancy verification method for train operation task generation verification and train operation path interface verification. When a single-point verification fails, the train can still be directed to run according to the predetermined path, thereby enhancing the safety and reliability of the system.

[0034] 2) The present invention designs a train path control verification and train operation status feedback verification mechanism, which verifies the two factors of active protection and passive correction, solving the problem that traditional signal systems are unable to prevent train path errors in mixed operation scenarios.

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.

[0044] like Figure 1 As shown, a rail transit multi-line mixed operation train path control method includes the following modules: a train and platform mapping module 1, a train operation main control module 2 and an on-board interface server module 3;

[0045] The train and platform mapping module 1 automatically generates the line attribute mapping relationship configuration data of the train and platform according to the system data;

[0046] The train operation main control module 2 includes the functions of setting the train single-step operation, the first terminal car and the planned car, providing the dispatch plan management function for the planned car, and verifying the consistency of the train operation path and the platform line attributes;

[0047] The on-board interface server module 3 verifies the validity of the train running path based on the received train running task and sends it to the train controller to control the train to run according to the specified path in real time; and receives the train's precise positioning information from the train controller to monitor the train running path in real time. When the train's predicted running path is inconsistent with the expected one, it actively sends a speed limit and immediate stop instruction to the on-board controller to correct the train running path in real time;

[0048] like Figure 2 As shown, the mixed operation line consists of platforms on Line 1 and Line 2, and there are co-line segments of platforms on Line 1 and Line 2.

[0052] Step 101: Create a train and line attribute mapping table, indicating that train Trian01 belongs to line Line1 and can only run on Line1 and the same line segment; train Trian02 belongs to line Line2 and can only run on Line2 and the same line segment; train Trian03 belongs to line Line1 and Line2 and can run on Line1, Line2 and the same line segment, and is a multi-line shared train;

[0055] <TrainID="03"LineID="1 / 2" / >

[0056] Step 102, define the platform identifier as Platform and the line identifier as Line;

[0057] Step 103: Create a platform and line attribute mapping table, indicating that platform Platform11 belongs to line Line1, platform Platform21 belongs to line Line2, and platform Platform01 belongs to a collinear segment.

[0077]

[0078] The train operation main control module includes the following steps:

[0079] Step 200, such as Figure 3 As shown, the train operation main control module includes the functions of setting single-step operation, setting the first car, and setting the scheduled car; setting single-step operation means that the train runs from the starting platform to the next adjacent platform; setting the first car means that the train runs according to the preset single loop path and has no subsequent running tasks after reaching the destination; setting the scheduled car means that the train runs according to the preset schedule path and automatically executes the next loop path after reaching the destination, realizing round-trip operation after connecting multiple loops;

[0080] Set up a single-step run task, taking Train01 as an example. Figure 4 As shown, the following steps are included:

[0081] Step 201: Check whether the train is a single-line dedicated train. If it is a dedicated train, proceed to step 202. If it is a shared line train, send the train task to the onboard interface server module.

[0082] Step 202: Check whether the starting platform is a collinear segment or has the same attributes as the train line.

[0083] Step 203: If the starting platform is verified as a co-linear segment or Line 1, the validity of the terminal platform is checked;

[0084] Step 204: If the terminal platform is verified to be a co-linear segment or Line 1 and is adjacent to the starting platform, the verification passes; if not, the verification fails.

[0085] Step 205: After the starting platform and the terminal platform are verified, the train single-step operation task is sent to the vehicle interface server module, including the starting platform, the terminal platform and the switches and positions in the path.

[0086] Set the first car task, such as Figure 5 As shown, taking Train01 as an example, the following steps are included:

[0087] Step 206, checking whether the train is a single-line dedicated train;

[0088] Step 207, checking whether the line attributes of the train destination terminal platform are consistent with the train line attributes;

[0089] Step 208: Check whether all platforms in the train's running path are single-line platforms or co-line segment platforms.

[0090] Step 209: After verification, the train operation task is sent to the train in the order of the platforms. When the train arrives at the next platform, the next operation task is sent to the train. Only one operation task is sent at a time.

[0091] Step 210: When the train arrives at the destination, clear the train operation task;

[0092] Setting up a planned train task, taking Train01 as an example, includes the following steps:

[0093] Step 211: Prepare a single route plan table, Schedule, which consists of multiple loops. The end point of the previous loop is the starting point of the next loop, so that multiple loops are connected end to end. Each station in the loop includes the arrival time and departure time.

[0094] Step 212: Multiple operation path plan tables form a plan map for the day;

[0095] Step 213: Prepare a dispatch plan. The dispatch plan indicates presetting a mapping relationship between trains and schedules, and assigning schedules to trains.

[0096] Step 214: Check whether the mapping relationship between the train and the schedule meets the conditions;

[0097] Step 215: Check whether the train is a shared train. If it is a shared train, directly match the schedule;

[0098] Step 216: If the train is a single-line dedicated train, check whether the line attributes of the starting platform, the destination platform, and all intermediate platforms in the first loop of the schedule assigned to the train are consistent with the train line attributes or are collinear platforms. If any of them are inconsistent, the match fails and the schedule is not allowed to be assigned to the train.

[0099] Step 217: cyclically check whether the line attributes of the platforms in other loops in the schedule are consistent with the line attributes of the train or are collinear platforms. If any of them are inconsistent, the matching fails and the sub-schedule is not allowed to be allocated to the train.

[0100] Step 218: If all platforms in the loop in the schedule meet the line attribute requirements, the schedule is matched for the train;

[0101] Step 219: After the match is successful, the train operation task is sent to the vehicle interface server according to the platform order and arrival and departure times in the loop. When the train arrives at the next platform, the next operation task is sent to the train. Only one operation task is sent at a time.

[0102] The onboard interface server module is an online real-time control module, including train operation path verification and train operation status feedback verification functions;

[0103] The running path control verification function, such as Figure 7 As shown, the following steps are included:

[0104] Step 300, loading the train and line attribute, platform and line attribute mapping table;

[0105] Step 301: Receive the running task of train Train01, starting from Platform01 and ending at Platform12;

[0106] Step 302: Train Train01 belongs to Line 1 and can only run on Line 1 and the same line segment;

[0107] Step 303: Verify that the line to which the starting platform Platform01 belongs is a collinear segment, and the verification succeeds.

[0108] Step 304: Verify that the line to which the terminal platform Platform12 belongs is Line1, and the verification succeeds.

[0109] Step 305: Train01 passes the path verification and sends the train01 running task to the onboard controller, with the starting point being Platform01 and the end point being Platform12. Switch01 remains in position.

[0110] Step 306: Receive the running task of train Train01, starting at Platform01 and ending at Platform21;

[0111] Step 307: Train Train01 belongs to Line1 and can only run on Line1 and the same line segment;

[0112] Step 308: Verify that the line to which the starting platform Platform01 belongs is a collinear segment, and the verification succeeds.

[0113] Step 309: Verify that the line to which the terminal platform Platform22 belongs is Line2, and the verification fails;

[0114] Step 310: Train01 fails the path verification, and the train operation command control process ends; the train operation control command is prohibited from being sent to the onboard controller;

[0115] Run path feedback verification function, such as Figure 8 As shown, the following steps are included:

[0116] Step 311: Receive the precise location of train Train01 and the train's expected running path from the onboard controller;

[0117] Step 312: Train01 is at platform Platform01 and is scheduled to arrive at platform 12. Switch01 is in the positioning phase. Verify that the train's scheduled platform reported by the onboard system is consistent with the local train's operating task and that the switch position is correct. Verification is successful.

[0118] Step 313: Train Train01 approaches the trigger rail position of switch Switch01. The train reports its expected arrival at station Platform12, and Switch01 is in the reverse position. The switch position is verified to be inconsistent with the expected position, and the verification fails. The train is prohibited from continuing to run, and a functional speed limit immediate stop command is sent to the train to prevent the train from entering other unexpected areas along the incorrect switch position.

[0119] Step 314: Train Train01 is at platform Platform01. The train is expected to arrive at platform Platform22. The platform for the train to arrive is checked and it is not passed. The train is prohibited from departing. If the train is skipped or has already departed from the platform, a speed limit immediate stop command is sent to the train to prevent the train from continuing to run into other unexpected areas.

If the verification passes, the train is controlled to run according to the planned time.

8. The rail transit multi-line mixed operation train path control system according to claim 1, characterized in that: After the on-board interface server module receives the train positioning from the on-board controller, when the train approaches the switch trigger rail, it verifies the consistency between the switch position ahead and the train running path. If the switch position verification fails, the train is prohibited from continuing to run, and a functional speed limit immediate stop command is sent to the train to prevent the train from continuing to run along the wrong switch position and entering other unexpected areas. If the verification passes, the train is controlled to run according to the planned time.

9. A method for a rail transit multi-line mixed operation train path control system according to any one of claims 1 to 8, characterized in that: The method includes: The train and platform mapping module automatically generates a train-to-line mapping relationship and a platform-to-line mapping relationship based on system data; The train operation main control module performs single-step train operation, head car and planned car control, and verifies the consistency of the train operation path and platform; The on-board interface server module verifies the validity of the train operation path based on the received train operation task and sends it to the train controller to control the train to run according to the specified path in real time; at the same time, it receives train positioning information from the train controller and monitors the train operation path in real time. When the predicted train operation path is inconsistent with the expected one, it actively sends a functional speed limit immediate stop instruction to the train controller to correct the train operation path in real time.

10. An electronic device comprising a memory and a processor, wherein a computer program is stored in the memory, wherein: When the processor executes the program, the method according to claim 9 is implemented.

11. A computer-readable storage medium having a computer program stored thereon, characterized in that: When the program is executed by a processor, the method according to claim 9 is implemented.
