Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a system for precise positioning and information verification of vehicles parked in a marshalling yard. Background Technology

[0002] The purpose of railway marshalling yard vehicle management is to memorize all available vehicle resources within the yard (tracks, shunting lines, no-running lines, detour lines, freight yard loading and unloading lines, depot maintenance lines, and dedicated lines, etc.), the current number of vehicles it can accommodate, vehicle information (car number, type, length, empty / loaded status, cargo name, weight, etc., derived from the train marshalling sequence table or loading line information), and storage order. This information changes dynamically with the operation of the marshalling yard and should be synchronized with the actual traffic flow.

[0003] Currently, the marshalling yard's integrated automation system automatically tracks vehicle reporting according to the work plan. This tracking is based on a logical judgment of whether the plan has been executed, but it doesn't check for potential deviations during plan execution. Therefore, like the old on-site vehicle management system, it lacks an automatic error detection and correction mechanism. If the actual operation deviates from the plan, it relies on reports from on-site personnel for manual correction; this method is known in the industry as "plan-tracking reporting." However, plan-tracking reporting is inaccurate and untimely. Once an error occurs, if it cannot be detected and corrected promptly, it will spread, making it very difficult to find and correct. It requires manual re-verification of vehicle numbers and manual tracking of the reported vehicle's movement, which is labor-intensive, inefficient, and prone to errors. Therefore, there is an urgent need for real-time collection and automatic verification of on-site vehicle information.

[0004] Currently, the existing vehicle tracking system at marshalling yards is crucial to the existing vehicle management information system. It requires the automatic feedback of real-time information on on-site operations such as marshalling and shunting; real-time statistics on the number of arriving trains in the arrival yard; and the collection of information from the shunting locomotive safety monitoring system to understand the operational status of all shunting locomotives in the station. The existing real-time vehicle tracking system at marshalling yards is merely an integrated information system. It relies on automatic feedback from the hump yard process control system, computer interlocking system, and shunting locomotive safety monitoring system; it collects detection information from vehicle identification, axle counting devices (wheel sensors), and freight vehicle loading status monitoring equipment distributed throughout the station's key areas; and it primarily relies on manual verification using handheld wireless terminals to locate and verify the information of vehicles remaining on the shunting lines after hump yard dismantling and marshalling operations. This achieves real-time tracking of all vehicles in the station, forming a comprehensive freight car information management system. For a long time, a problem hindering railway marshalling yard information management systems has been the inaccuracy of the actual vehicle situation—it is not a real-time situation, hence the term "planned vehicles." Dispatchers need to know the current operational status when creating plans, which can only be obtained through information displayed on the route light strips and signals of the dispatching system. They must compare this information with previously created plans, deduce and guess the steps to be executed in the current plan, or confirm via telephone. On the other hand, updating and changing the data of the vehicles in the plan relies entirely on different people at different times and locations through manual operation, which is a huge workload and carries the potential for human error. Summary of the Invention

[0005] The purpose of this invention is to provide a precise positioning and information verification system for vehicles parked in a marshalling yard, which can realize real-time collection and automatic verification of vehicle information at the station, thereby better managing vehicles and improving utilization efficiency; and it can be automated, which can improve working conditions and reduce labor intensity.

[0006] The objective of this invention is achieved through the following technical solution:

[0008] The precise positioning and information collection device for cars parked in the marshalling yard is installed within the marshalling yard tracks. It is used to collect information on cars parked on the shunting lines according to control commands; to obtain the end direction of cars entering and leaving the shunting lines during marshalling and demarcation operations; to collect information on shunted cars entering and leaving the shunting lines each time; to collect real-time information on shunted cars entering the shunting lines during hump yard demarcation operations; to collect real-time information on cars parked at the tail of the shunting lines during tail-end shunting and shunting operations; and to collect relevant car information during traction operations from the marshalling yard to the departure yard.

[0009] The trackside control host equipment is used to forward control commands to the precise positioning and information collection device for cars parked in the marshalling yard of the marshalling yard, and to receive various types of vehicle information collected by the precise positioning and information collection device for cars parked in the marshalling yard of the marshalling yard;

[0010] The system server is connected to the communication interface equipment of the marshalling yard integrated automation system. It receives various shunting operation plan information from the marshalling yard integrated automation system, receives and verifies various vehicle information collected by the precise positioning and information collection device of the vehicles parked in the marshalling yard. After verification, it sends the information of various parked vehicles to the marshalling yard integrated automation system. The system server also stores a complete backup of the current vehicle data. After receiving a data read instruction from the marshalling yard integrated automation system, it sends the complete backup of the current vehicle data to the marshalling yard integrated automation system.

It is a foundation and important means for improving the management and control level of marshalling yards in the future. Attached Figure Description

[0016] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0017] First, the following explanations are provided for the terms that may be used in this article:

[0018] The terms “including,” “comprising,” “containing,” “having,” or other similar semantic descriptions should be interpreted as non-exclusive inclusion. For example, “including a technical feature element (such as raw material, component, ingredient, carrier, dosage form, material, size, part, component, mechanism, device, step, process, method, reaction conditions, processing conditions, parameter, algorithm, signal, data, product or article of manufacture, etc.)” should be interpreted as including not only the expressly listed technical feature element, but also other technical feature elements that are not expressly listed and are well-known in the art.

[0019] The following is a detailed description of the precise positioning and information verification system for stationary vehicles in a marshalling yard provided by this invention. Contents not described in detail in the embodiments of this invention are prior art known to those skilled in the art. Where specific conditions are not specified in the embodiments of this invention, they are performed according to conventional conditions in the art or conditions recommended by the manufacturer. Instruments used in the embodiments of this invention, unless otherwise specified by the manufacturer, are all commercially available conventional products.

[0020] This invention provides a system for precise positioning and information verification of cars parked in a marshalling yard, such as... Figure 1As shown, it mainly includes: a precise positioning and information collection device for cars parked in the marshalling yard (numbered 1 to n), a trackside control host equipment, and a system server; the precise positioning and information collection device for cars parked in the marshalling yard is installed in the marshalling yard track and is used to collect information on cars parked on the shunting line according to control commands; it is used to obtain the end direction of cars entering and leaving the shunting line during marshalling and demarcation operations in the marshalling yard, collect information on shunting cars entering and leaving the shunting line each time, collect information on shunting cars entering the shunting line in real time during hump demarcation shunting operations, collect information on cars parked at the tail of the shunting line in real time during tail-end shunting and shunting operations, and collect relevant car information during traction operations from the marshalling yard to the departure yard; the precise positioning and information collection device for cars parked in the marshalling yard transmits data to the trackside control host equipment wirelessly, and the trackside control host equipment forwards control commands to the precise positioning and information collection device for cars parked in the marshalling yard, and receives... The marshalling yard's precise vehicle positioning and information collection device gathers various vehicle information. The trackside control host equipment communicates with the marshalling yard's precise vehicle positioning and information verification system server (hereinafter referred to as the system server) via a fiber optic network, receiving control commands from the system server and uploading the various vehicle information collected by the device. The system server is connected to the marshalling yard's integrated automation system communication interface equipment, receiving various shunting operation plan information from the integrated automation system and verifying it against the vehicle information collected by the device. If the verification is correct, the system server sends the vehicle information to the integrated automation system. The system server also stores complete backups of current vehicle data. Upon receiving a data read command from the integrated automation system, the system server sends the complete backup data to the integrated automation system. This system server provides the marshalling yard's integrated automation system with the technical means to monitor various vehicle information (number of vehicles, parking location, vehicle number, and vehicle sequence number, etc.) in real time.

[0021] In addition to the functions described above, the trackside control host equipment can also determine whether the precise positioning and information collection device for vehicles parked in the marshalling yard is working properly based on its operating status. It can also manually operate the precise positioning and information collection device and manage its wireless charging function. The wireless charging mentioned here refers to wirelessly charging the power battery components in the precise positioning and information collection device.

[0022] In this embodiment of the invention, the precise positioning and information collection device for stationary vehicles in the marshalling yard automatically performs the corresponding vehicle information collection work according to the current operation type of the marshalling yard. For example, when de-marshalling vehicles are moved in and out of the shunting line by a shunting locomotive (marshalling operation in the shunting yard), the system can automatically know the end direction of the vehicles entering and leaving the shunting line, and collect the vehicle information for each entry and exit, including: the number of vehicles, parking position, vehicle number, and vehicle sequence number; after the single-coupling shunting operation is completed, the system automatically updates the number of vehicles stored on the shunting line, parking position, vehicle number, and vehicle sequence number. All of the above processes are completed automatically by the system. As needed, instructions can be sent at any time to the precise positioning and information collection device for stationary vehicles in the marshalling yard of a certain track to scan the electronic tags of the vehicles stored on the shunting line, collect the stationary vehicle information of the stationary vehicles stored on the shunting line, and regenerate the vehicle sequence. The stationary vehicle information and other vehicle information include: the number of vehicles, parking position, vehicle number, and vehicle sequence number. In addition, it also includes: the idle length at the end of the track, the position, quantity, and length of the track window, etc.

[0023] In this embodiment of the invention, the precise positioning and information collection device for parked vehicles in the marshalling yard is equipped with millimeter-wave ranging radar and vehicle identification and positioning sensors. It can dynamically locate and identify the actual position of each parked vehicle within the marshalling yard tracks, measure the clearance between parked vehicles and the empty length at both ends of the shunting track, and automatically scan and identify the electronic tags of each parked vehicle within the marshalling yard tracks. This enables real-time collection and automatic verification of vehicle information within the marshalling yard, facilitating actual vehicle operations. This system, combined with hump yard dismantling and tail-end marshalling operations, forms an innovative model for precise positioning and information verification of parked vehicles in the marshalling yard. It improves the overall efficiency of dismantling and marshalling operations, solving all problems under the condition of comprehensive automation at the marshalling yard. It achieves smooth and shared information flow in freight organization and production operations, serving as a foundation and important means to improve the management and control level of marshalling yards in the future.

[0024] like Figure 2 As shown, this illustrates the system's workflow during shunting operations (disassembly and marshalling) in a shunting yard.

[0025] 1) The dismantling operation corresponds to the hump dismantling operation mentioned above. At this time, the precise positioning and information collection device for vehicles parked in the marshalling yard of the marshalling yard will collect the information of the shunting vehicles entering the shunting line in real time. After being automatically verified by the system server, the information is uploaded to the marshalling yard integrated automation system to realize real-time automatic tracking of the dismantled vehicles.

[0026] 2) The marshalling operation corresponds to the marshalling and demarcation operations described earlier. When vehicles enter or leave the shunting line, the precise positioning and information collection device for vehicles parked in the marshalling yard of the marshalling station can automatically determine the direction of entry and exit from the shunting line, as well as the number, car number, and sequence number of vehicles entering and leaving the shunting line each time. After the single-coupling shunting operation is completed, the number, car number, and sequence number of vehicles stored on the shunting line are automatically updated. Furthermore, as needed, the on-site data collection device can be controlled at any time to automatically perform round-trip data collection on the parked vehicles on the shunting line, regenerate the vehicle sequence, and provide the marshalling station's integrated automation system with the information required for compiling the marshalling operation plan, including the idle length of the tracks at both ends of the shunting line, the coupling status of the shunted vehicles, and the number, location, and length of track openings.

[0027] All vehicle information collected during various operations needs to be verified. Once verified, it is provided to the marshalling yard's integrated automation system. Taking dismantling and marshalling operations as examples, verification means that the collected vehicle information is consistent with the information in the corresponding dismantling and marshalling operation plans.

[0028] In addition, control commands can be issued ( Figure 2 The system sends a control command (instructions) to the precise positioning and information collection device for parked cars in the marshalling yard. This device then travels back and forth along the shunting line to collect information on parked cars. The control command is typically forwarded from the system server to the device. The device then uploads the collected information to the system server via the trackside control host equipment. The system server then compares the collected information with the planned parked car data from the marshalling yard's integrated automation system. Before comparison, the accuracy of the collected data can be assessed individually. For example, the collected information can be divided into two sets. If the two sets match, the data is accurate. One set is then compared with the planned parked car data from the marshalling yard's integrated automation system. If the two sets do not match, another round of data collection is required until the two sets match.

[0029] In the aforementioned scheme, the information on vehicles parked in the marshalling yard (information on vehicles distributed across each shunting line, including parking location, vehicle sequence number, track end clearance length, track maintenance window location, quantity, and length) is of paramount importance to railway transportation. From a macro perspective, real-time collection and automatic verification of vehicle information parked in the marshalling yard allows for an understanding of the overall network transportation situation, enabling timely relief measures in case of congestion; it also facilitates better vehicle management and improves operational efficiency. Simultaneously, marshalling yards are the main distribution centers for railway freight vehicles, and the vehicle information and distribution data of the marshalling yards are crucial for tracking freight vehicles across the network. This is essential for current vehicle management, traffic flow calculation, and the development and optimization of dismantling and marshalling plans; it is also significant for improving the operation and management of marshalling yards, reducing transfer time, decreasing staff and increasing efficiency, improving working conditions, and alleviating labor intensity.

[0030] To more clearly demonstrate the technical solutions and effects provided by the present invention, the following detailed description of the solutions provided by the embodiments of the present invention is provided with reference to specific examples.

[0031] I. Precise positioning and information collection device for vehicles parked in the marshalling yard of the marshalling yard.

[0032] In this embodiment of the invention, the precise positioning and information collection device for cars parked in the marshalling yard is installed within the marshalling yard tracks, such as... Figure 3As shown, a millimeter-wave tracking speed and distance measuring radar, a displacement sensor, a power battery assembly, a portion of a linear motor assembly, a stationary vehicle positioning and identification sensor, and a control host are mounted on the moving car body. Another portion of the linear motor assembly is located at the center of the track (not shown). Together, they constitute a precise positioning and information collection device for stationary vehicles in a marshalling yard. The millimeter-wave tracking speed and distance measuring radar includes several (e.g., one) millimeter-wave vehicle-mounted speed measuring radars and several (e.g., two) millimeter-wave tracking and distance measuring radars, which are located at the front and rear ends of the moving car body. The stationary vehicle positioning and identification sensor includes a vehicle number reader and a vehicle positioning sensor. The linear motor includes a linear motor mover and a linear motor stator sensing aluminum plate. The linear motor mover is mounted on the moving vehicle body, and the linear motor stator sensing aluminum plate is positioned at the center of the track. Specifically, the length of the linear motor stator sensing aluminum plate extends along the entire shunting yard, from the three exits to the rear parking device entrance. The device provided by this invention is installed at the center of the track, at the bottom of the vehicle. Activating this device allows for the collection of vehicle information along the entire shunting yard. The linear motor stator sensing aluminum plate serves as the track for the moving vehicle body's pulleys, enabling the moving vehicle body to move on the track. The stationary vehicle positioning and identification sensor, power battery assembly, displacement sensor, millimeter-wave tracking speed and distance measuring radar, and linear motor are all connected to the control host. The displacement sensor is responsible for sensing the displacement distance of the moving vehicle body. The control host is equipped with a wireless communication board, enabling data communication with external devices (i.e., trackside control host equipment). It is responsible for communicating with the trackside control host equipment (sending and receiving data information), controlling the millimeter-wave tracking speed and distance measuring radar and the stationary vehicle positioning and identification sensor to collect vehicle information, and controlling the movement of the moving vehicle body by controlling the linear motor. The stationary vehicle positioning and identification sensor can automatically locate and identify the actual position of each stationary vehicle in the marshalling yard track; the millimeter-wave tracking speed and distance measuring radar can measure the skylights between stationary vehicles and the clear length at both ends of the marshalling line track. Combined with hump yard dismantling operations and tail-end shunting operations, a new mode of precise positioning and information verification of stationary vehicles in the marshalling yard is formed. This provides the marshalling yard's integrated automation system with real-time information on the number of stationary vehicles, their positions, vehicle order, vehicle numbers, clear length at both ends of the track, and coupling status of shunting vehicles, thereby improving the overall efficiency of dismantling and marshalling operations in the marshalling yard.

[0033] II. System Working Process.

[0034] In this embodiment of the invention, the system can be applied to various types of operations, and the system server has a communication interface with the marshalling yard integrated automation system, which can receive corresponding shunting operation plan information and complete the information verification work by combining the real-time vehicle information automatically collected by the system with the shunting operation plan.

[0035] 1. Shunting and unloading operations in the shunting yard.

[0036] In this embodiment of the invention, during the process of vehicles entering and exiting the shunting line, the system can automatically know the direction of vehicles entering and exiting the shunting line, as well as the number, car number, and sequence number of vehicles entering and exiting the shunting line each time. After the single-coupling shunting operation is completed, the system automatically updates the number, car number, and sequence of vehicles stored on the shunting line. This solves the problem that vehicle position transfers in existing existing vehicle systems must be manually operated, and the consistency between the data status of the existing vehicle storage area and the actual vehicle status outdoors must be ensured by manual operation. Specifically: at both ends of the shunting line, the side closer to the hump dismantling shunting operation is the hump head end, and the side closer to the marshalling and shunting operation is the marshalling tail end. When the shunting yard is performing marshalling and shunting operations (or hump dismantling operations), the system receives the start information of the marshalling and shunting plan (or dismantling shunting plan) and automatically knows the direction of each shunting vehicle entering and exiting the shunting line through millimeter-wave tracking speed and distance measuring radar and stationary vehicle positioning and identification sensors.

[0037] As needed, the precise positioning and information verification system for parked vehicles in the marshalling yard can control the precise positioning and information collection device of the marshalling yard to automatically collect information on parked vehicles on the shunting line, regenerate vehicle sequence, and measure the idle length of the tracks at both ends of the shunting line, the coupling status of the shunting vehicles, and the number, location, and length of track openings. This information is provided to the marshalling yard's integrated automation system for the preparation of station shunting operation plans.

[0038] During marshalling and demarcation operations, when a vehicle enters from the three-stage reduction gearbox at the hump or crosses the marshalling yard from the tail stop, real-time data can be collected on the vehicle entering the track, the length of the empty space at both ends of the track, and the length of the skylight position. The precise positioning and information collection device for parked vehicles in the marshalling yard collects vehicle information, the length of the empty space at both ends of the track, and the length of the skylight position in a single round trip, based on the data collected after the shunting vehicle has come to a stop.

[0039] 2. Provides a means of backing up the underlying equipment for the current vehicle data of the marshalling yard's integrated automation system.

[0040] The number of wagons parked at all shunting lines and changes in their order are automatically completed by the marshalling yard's precise vehicle location and information verification system. When the ticket information associated with a wagon changes, the marshalling yard's integrated automation system automatically backs up the wagon information to the precise vehicle location and information verification device and its system. When the wagon database malfunctions and data is lost, complete backup data can be retrieved directly from this system by station, yard, and line, greatly reducing the risk of prolonged transportation disruptions caused by wagon database failures.

[0041] Meanwhile, when the current vehicle database of the marshalling yard's integrated automation system malfunctions, resulting in the loss of current vehicle data, relevant instructions can be sent to the system server to control the precise positioning and information collection devices for parked vehicles in the marshalling yard to perform full-line scanning and identification of every parked vehicle on any shunting line at any time. This collects information on parked vehicles on the shunting line, regenerates vehicle sequence information, and provides it to the marshalling yard's integrated automation system, thus providing an underlying equipment support platform for backing up current vehicle data for the marshalling yard's integrated automation system.

[0042] 3. Hump dismantling and shunting operations.

[0043] During hump yard dismantling operations, the precise positioning and information collection device for vehicles parked in the marshalling yard automatically collects real-time information on vehicles entering the shunting line at the exits of three decelerators. The system server automatically verifies this information in conjunction with the corresponding shunting operation plan and uploads it to the marshalling yard's integrated automation system, enabling real-time automatic tracking of dismantled and shunted vehicles. Furthermore, it can also measure information such as the time windows between vehicles and the idle length at both ends of the shunting line tracks in real time. Using the system's operation performance report (i.e., the information collected by the system), the vehicle storage sequence table for the marshalling yard's shunting line tracks can be automatically modified.

[0044] 4. Shunting operations at the tail end of the wagon and shunting by shunting.

[0045] During marshalling and shunting operations, the precise positioning and information collection device for cars parked at the tail of the marshalling yard automatically collects accurate position information of the cars parked at the tail of the shunting line. Based on the actual position information of the parked cars, it can automatically generate shunting operation safety information such as "position of ten cars, position of five cars, position of three cars" and "coupling speed requirements", and upload it to the automated marshalling and shunting plan information subsystem of the marshalling yard. The shunting operation safety information is directly printed on the shunting operation notification sheet, realizing joint control of marshalling and shunting operation safety.

[0046] 5. Traction operations from the shunting yard to the departure yard.

[0047] During the traction operation from the shunting yard to the departure yard, the precise positioning and information collection device for the cars parked in the marshalling yard automatically reads the car number information. After the system server automatically verifies the car number of each car in the train set, it is uploaded to the marshalling yard's integrated automation system to ensure the accuracy of the car storage sequence table on the departure yard track. This serves as the basis for automatically generating the departure train marshalling sequence table, overcoming the inherent defects of the existing system's plan tracking delay and manual verification.

[0048] In this embodiment of the invention, during various operations, control commands can be issued to control the precise positioning and information collection device for the marshalling yard vehicles in the corresponding track to collect vehicle information once in a round trip. The system server then processes the information into two sets of vehicle information. When the two sets of vehicle information are consistent, vehicle sequence information is generated and stored.

[0049] In this embodiment of the invention, the vehicle information collected, based on the type of operation, includes the following:

[0050] 1) Basic vehicle information such as vehicle number and vehicle type (open wagon, covered wagon, tanker, container wagon); 2) Freight information such as destination station, departure station, and cargo name; 3) Vehicle location such as yard (arrival yard, shunting yard, departure yard, etc.), track, and vehicle sequence; 4) Vehicle destination; 5) Vehicle status such as empty / loaded.

[0051] In this embodiment of the invention, a precise positioning and information verification system for vehicles parked in the marshalling yard is adopted, enabling intelligent closed-loop management of vehicle information in the marshalling yard. Combined with dismantling and marshalling operations, the system automatically locates vehicles involved in hump yard dismantling operations and the available length of tracks at both ends of the marshalling line in real time. The system also automatically modifies the vehicle storage sequence table of the marshalling yard tracks using its vehicle database, achieving a novel and innovative model for accurate positioning and real-time verification of vehicle information management in marshalling yards.

[0052] The above-mentioned solutions provided by the embodiments of the present invention:

[0053] 1) It provides the marshalling yard's integrated automation system with the technical means to monitor in real time information such as the number of cars stored on the shunting line, car sequence, car number, track clearance length, and the coupling status of shunted cars. During dismantling or marshalling operations, the entire process is completed automatically by the system, solving the problems of manual operation of car location information and the need for human intervention to ensure consistency between the data status of the existing vehicle management system and the actual status of vehicles outdoors.

[0054] 2) It provides a means of backing up the underlying equipment for the marshalling yard's integrated automation system, greatly reducing the risk of prolonged transportation production interruptions caused by the failure of the current vehicle database. Changes in the number and order of vehicles on all shunting lines are automatically completed by the marshalling yard's precise vehicle location and information verification system. When information in the current vehicle database changes, it is automatically backed up to the marshalling yard's precise vehicle location and information verification system. When a failure in the current vehicle database results in missing current vehicle data, complete backup data can be directly retrieved from the marshalling yard's precise vehicle location and information verification system by station, yard, and line.

[0055] 3) The real-time accurate positioning and automatic verification of hump yard dismantling vehicles, as well as the function of correcting the departure train formation sequence, provide the marshalling yard's integrated automation system with the information needed to compile shunting operation plans, including the available length of tracks at both ends of the shunting line, the coupling status of shunted vehicles, and the number, location, and length of track openings. With this information, both hump yard dismantling and marshalling operations can support the marshalling yard's integrated automation system in automatically compiling shunting operation plans, greatly improving the predictability of shunting operations and reducing gate congestion.

[0056] 4) It provides the marshalling yard's integrated automation system with accurate location information of the shunting cars parked on the marshalling yard's tail-end shunting and shunting operations, reducing the safety control risks for indoor and outdoor shunting personnel.

[0057] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

The system for precise positioning and information verification of cars parked in a marshalling yard as described in claim 1, characterized in that, When the current vehicle database of the marshalling yard integrated automation system is missing, the system server will receive the instruction issued by the marshalling yard integrated automation system. According to the instruction, the system server will control the precise positioning and information collection device of the marshalling yard to perform full-line scanning and identification of every vehicle parked in any shunting line, collect the information of the vehicles parked in the shunting line, regenerate the vehicle sequence information and provide it to the marshalling yard integrated automation system.

4. A precise positioning and information verification system for shunting vehicles in a marshalling yard according to any one of claims 1 to 3, characterized in that, When collecting information on parked cars on the shunting track according to control commands, the precise positioning and information collection device for parked cars in the marshalling yard of the marshalling yard collects the parked car information once in one round trip. This information is then uploaded to the system server via the trackside control host equipment. The system server compares the collected parked car information with the planned parked car data from the marshalling yard's integrated automation system. Before comparison, the system server assesses the accuracy of the data by organizing the parked car information collected by the precise positioning and information collection device into two sets of data. If the two sets of data match, the collected data is accurate. One set is then compared with the planned parked car data from the marshalling yard's integrated automation system. If the two sets of data do not match, the system continues to collect parked car information once in one round trip until the two sets of data match.
