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] At present, urban rail transit has realized network operation, with a surge in passenger flow, an increase in the transportation capacity demand of the backbone lines in the urban core area, and an increasing demand for multi-line mixed operation. In multi-line mixed operation, some trains are dedicated trains for fixed lines. Due to the inconsistency of vehicle models, platform widths, and lengths, they can only enter the common line platform and the dedicated line platform, and cannot enter other line areas; some trains are multi-line shared trains, which can run on the common line platform and different lines. The existing rail transit signal control system uses the route to allocate running path resources for trains. When the route error is triggered, it can only rely on the driver to observe the status of the signal machine in front and the dispatcher to observe the status of the line equipment for manual confirmation. The signal control system cannot 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 state of using line resources 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 and prevent trains from entering unexpected platform areas in a multi-line mixed operation scenario 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 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, there is provided a rail transit multi-line mixed operation train path control system, the system is connected to a train controller, the system comprises a train and platform mapping module, a train operation main control module and a vehicle-mounted interface server module connected in sequence, the vehicle-mounted interface server module is connected to the train controller;

[0007] The train and platform mapping module automatically generates a mapping relationship between train lines and a mapping relationship between platforms according to system data;

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

[0009] The on-board interface server module verifies the validity of the train operation path according to 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 mapping relationship between the train and the platform is as follows:

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

[0012] Read the platform number information and the line information to which the platform belongs in 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. 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 are verified, 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 are verified, the train single-step operation task is refused to be sent to the on-board interface server module.

[0015] As a preferred technical solution, the train operation main control module performs the following steps to control the head vehicle:

[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 platform order, 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] A planned train task is set 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 main control module performs dispatch planning management for the planned vehicle, 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, the schedule is directly matched;

[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 in 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 a preferred 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 arrival 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 a preferred 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 line attributes of the train. 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 a preferred technical solution, after the on-board interface server module receives the train position 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 a rail transit multi-line mixed operation train path control system is provided, the method comprising:

[0027] The train and platform mapping module automatically generates a mapping relationship between train lines and a mapping relationship between platforms according to system data;

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

[0029] The on-board interface server module verifies the validity of the train operation path according to 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, 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.

[0031] According to a fourth 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 when executed by a processor.

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

[0033] 1) The present invention designs a dual redundant 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 running path control verification and train running status feedback verification mechanism, which verifies from two levels of factors: active protection and passive correction, solving the problem that traditional signal systems are unable to prevent train running path errors in mixed operation scenarios.

[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 wharf 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 wharf car means that the train runs according to the preset single Loop path, and there is no subsequent running task after reaching the end point; 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 end point, realizing round-trip operation after multiple Loops are connected;

[0080] Set up a single-step running 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, go to step 202, if it is a common line train, send the train task to the vehicle-mounted interface server module;

[0082] Step 202, checking whether the starting platform is a co-linear segment or is consistent with the train line attribute;

[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-mounted interface server module, including the starting platform, the terminal platform and the switches and positions in the path of the task.

[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 attribute of the train destination terminal platform is consistent with the train line attribute;

[0089] Step 208, checking whether all platforms in the train running path are single-line platforms or co-line segment platforms;

[0090] Step 209: after the verification is passed, the train operation task is sent to the train according to the platform order. 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 the planned train task, taking Train01 as an example, includes the following steps:

[0093] Step 211, compile a single running path schedule 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 contains the arrival time and departure time.

[0094] Step 212, multiple operation path plan tables form a daily plan map;

[0095] Step 213, compile a dispatch plan, the dispatch plan means presetting a mapping relationship between trains and schedules, and assigning schedules to trains;

[0096] Step 214, checking 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 terminal platform, and all the intermediate platforms in the running path in the first loop of the schedule table Schedule allocated to the train are consistent with the train line attributes or are co-line platforms. If any of them is inconsistent, the matching fails and the schedule is not allowed to be allocated to the train;

[0099] Step 217, cyclically checking whether the line attributes of the platforms in other loops in the schedule are consistent with the line attributes of the train or are co-line 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 the platforms in all loops in the schedule 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 time 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 on-board interface server module is an online real-time control module, including train running path verification and train running status feedback verification functions;

[0106] Step 302, the line to which the train Train01 belongs is Line1, and the train can only run on Line1 and the co-line segment;

[0107] Step 303, verify that the line to which the starting platform Platform01 belongs is a common line segment, and the verification is successful;

[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 train Train01 running task to the onboard controller, with the starting point Platform01 and the end point Platform12, and the switch Switch01 remains in position;

[0110] Step 306, receiving the running task of train Train01, starting point Platform01, and ending point Platform21;

[0111] Step 307, the line to which the train Train01 belongs is Line1, and the train can only run on Line1 and the co-line segment;

[0112] Step 308, verify that the line to which the starting platform Platform01 belongs is a co-line segment, and the verification is successful;

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

[0114] Step 310: If the train Train01 fails the path check, the train operation command control process ends; it is forbidden to send the train operation control command to the onboard controller;

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

[0116] Step 311, receiving the precise location of train Train01 and the expected running path of the train from the onboard controller;

[0117] Step 312, Train01 is at Platform01, and the train is expected to arrive at Platform12. Switch01 is in the positioning state. Verify that the train expected platform feedback from the vehicle is consistent with the local train operation task, and the switch position is correct, and the verification is passed;

[0118] Step 313, the train Train01 runs to the trigger rail position close to the switch Switch01, and the train feedbacks the expected running to the station Platform12, the position of Switch01 is in the reverse position, and the switch position is not consistent with the expected position. The verification fails, and the train is prohibited from continuing to run. A functional speed limit immediate stop command is sent to the train to prevent the train from entering other unexpected areas along the wrong position of the switch;

[0119] Step 314, train Train01 is at platform Platform01, and the train is expected to run to platform22. The platform for the train to run to is checked and it does not pass, and the train is prohibited from departing. If the train is skipped or the train has already departed from the platform, a functional speed limit immediate stop command is sent to the train to prevent the train from continuing to run into other unexpected areas.

If they are consistent, it sends it to the train controller. If they are inconsistent, it refuses to send the train operation command to the train controller.

9. A rail transit multi-line mixed operation train path control system according to claim 1, characterized in that: 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 line attributes of the train. 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.

10. A 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 location 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.

11. A method for a rail transit multi-line mixed operation train path control system as claimed in any one of claims 1 to 10, characterized in that: The method includes: The train and platform mapping module automatically generates a mapping relationship between train lines and a mapping relationship between platforms according to system data; The train operation main control module performs single-step operation of the train, control of the head car and the planned car, and verifies the consistency of the train operation path and the platform; The on-board interface server module verifies the validity of the train operation path according to 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.

12. 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 11 is implemented.

13. 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 11 is implemented.
