[0002] With the increasing demand for private cars in daily life, the annual output of automobile manufacturers has also increased dramatically. According to research, newly produced cars in vehicle factories are manually driven from the production line buffer area to the warehouse. Due to the very high rate of car production, this often leads to vehicle backlogs in the buffer area. This transfer work requires a large amount of manpower and is greatly affected by weather conditions. Currently, the most mature car transfer system on the market is the Ray robot from the German company Serva.

[0010] Furthermore, the AGV scheduling system adopts a "feedforward locking" approach to manage traffic for car transport AGVs.

[0033] Example 1

[0034] One specific embodiment of the present invention discloses a control system for the automatic transfer of newly manufactured automobiles, such as... Figure 1 As shown, the system includes an attitude measurement system, a car handling AGV, an AGV scheduling system, a vehicle-road cooperative system, a charging module, a parking space induction coil, and a wireless communication system. The attitude measurement system, car handling AGV, AGV scheduling system, vehicle-road cooperative system, charging module, and vehicle induction coil establish a communication connection through the wireless communication system. This enables information exchange between the attitude measurement system, car handling AGV, AGV scheduling system, vehicle-road cooperative system, charging module, and vehicle induction coil, and controls the car handling AGV to automatically transfer newly produced cars. This saves labor costs while ensuring that the transfer of cars on the production line is not affected by weather or other environmental factors, improving the production line's production efficiency and further realizing digital management of the entire process of a vehicle from production line to warehouse storage and sales.

[0035] Preferably, the wireless communication system uses MOXA AWK-3131A and MOXA AWK-4131A modules. The AWK-3131A is installed at the AGV end and configured in Client mode. The AWK-4131A module is used to deploy a wireless local area network in the parking lot. This module is configured in AP mode to ensure good wireless communication.

[0036] Preferably, the attitude measurement system is installed at the receiving area parking space at the end of the automobile production line. The attitude measurement system performs pose recognition on the newly produced automobile at the receiving area parking space based on the vehicle frame number data, and can obtain the pose data of the newly produced automobile. The pose data format is (X; Y; θ; CarWheelbase; VIN), where X, Y, and θ are the coordinate information of the center point of the newly produced automobile in the geodetic coordinate system, CarWheelbase is the wheelbase of the newly produced automobile, VIN is the vehicle frame number of the newly produced automobile, and θ is the angle between the line connecting the center point of the newly produced automobile and the origin of the receiving area parking space coordinate system and the Y-axis of the receiving area parking space coordinate system. The attitude measurement system is connected to a wireless communication system, specifically establishing a communication connection with the AGV scheduling system through the TCP protocol, which can realize the transmission of the pose data of the newly produced automobile measured by the attitude measurement system to the AGV scheduling system.

[0037] Preferably, the attitude measurement system includes a barcode scanner, a binocular camera, and a 600-line lidar. The barcode scanner is used to scan the vehicle identification number (VIN) of newly manufactured vehicles.

[0038] Preferably, at least one binocular camera is provided, and in this embodiment, two binocular cameras are preferably provided. The two binocular cameras are respectively arranged on the long frame on both sides of the parking space in the receiving area, and are used to take pictures of the side of the newly produced car parked in the parking space in the receiving area to generate a 2D image. At the same time, they acquire information on four wheels and the relative relationship between the parked vehicle and the parking space frame. The wheel information includes the coordinates of the center point of the wheel in the coordinate system of the parking space in the receiving area, the diameter, and the wheelbase. The 600-line lidar is set above the parking space in the receiving area, and is used to scan the newly produced car parked in the parking space in the receiving area to generate point cloud data of the scanned area. The point cloud data model of the whole vehicle is fitted with the model of the newly produced car retrieved from the vehicle yard database using the least squares method. The point cloud data model is the three-dimensional model of the newly produced car.

[0039] Preferably, the attitude measurement system combines information from four wheels with a point cloud data model, uses OpenCV and YOLO_V5 image processing algorithms to extract key feature points of the vehicle body, and calibrates the coordinates of these key feature points in the parking lot coordinate system; for example... Figure 2 As shown, the key feature point is the outermost point above the wheel hub. The relative positional relationship between this point and the vehicle center point is fixed and known. The coordinates of the vehicle center point in the parking space coordinate system of the receiving area are calculated by the positional relationship between the key feature point and the vehicle center point. The coordinates of the vehicle center point in the geodetic coordinate system are then obtained by coordinate transformation. In this way, the pose data of the newly produced car in the geodetic coordinate system can be obtained. The pose data of the newly produced car measured by the attitude measurement system can be transmitted to the AGV scheduling system.

[0040] Preferably, the AGV scheduling system includes a backend algorithm module and a web frontend display module. The backend algorithm module receives transfer task orders from the production management system, dispatches car transport AGVs according to the transfer task orders, plans the optimal path for the car transport AGVs based on their locations, registers the optimal path in the AGV scheduling system, allocates the optimal path resources to the corresponding car transport AGVs, and schedules the corresponding car transport AGVs to perform transfer tasks. The web frontend display module is used for human-computer interaction and information display, allowing users to view car transport AGV attributes, including car transport AGV charging control, car transport AGV online / offline control, car transport AGV emergency stop / resumption of motion control, map display and loading, and other functions.

[0041] Preferably, the AGV scheduling system adopts a "feedforward locking" approach to control traffic for car transport AGVs. The "feedforward locking" means that when a car transport AGV needs to move, it converts the movement command into a traffic control resource and registers it with the AGV scheduling system before moving. Only when the resource is successfully registered and accepted by the AGV system will the AGV scheduling system send a travel command to the car transport AGV, and only then will the car transport AGV move.

[0042] Preferably, the AGV scheduling system dynamically modifies the coordinates of corresponding points in the scene map, and schedules or manages traffic for multiple car transport AGVs based on road information fed back by the vehicle-road cooperative system, motion information reported by the car transport AGVs themselves, and the position and pose information of the newly produced cars, so as to avoid collisions between car transport AGVs and ultimately control the car transport AGVs to complete the transfer of the newly produced cars.

[0043] Preferably, the vehicle-road cooperative system includes a road environment perception system, an edge computing unit, and a vehicle perception central processing module. The vehicle-road cooperative system is used to effectively control mutual avoidance among people, vehicles, and AGVs in mixed traffic situations to prevent accidents. It can also scan and locate obstacles on the road segment and send the scanned obstacle information to the AGV scheduling system, which then controls the AGVs to stop or resume movement. The vehicle-road cooperative system can prevent safety accidents on the route and ensure the safety of vehicles and personnel.

[0044] Preferably, the road environment perception system includes roadside radar, cameras, and road induction coils laid at intersections to detect whether vehicles are passing through the road section; the roadside radar and cameras are both mounted at a height of 6 to 8 meters above the ground, which can monitor all traffic participants on the road in real time, and at the same time capture images of designated lanes to form video or pictures and other data.

[0045] Preferably, the edge computing unit performs calculations on the received video or image data of the designated lane within the area to obtain road environment information such as the category, number, shape, position and movement status of the participants in the designated lane, and reports the processed information to the vehicle perception central processing module and the AGV scheduling system.

[0046] Preferably, the vehicle perception central processing module adopts a microservice framework to determine the priority order of car transport AGVs, people, and vehicles passing through intersections. Based on the principle of who enters the intersection first and who passes first, it controls traffic facilities such as traffic poles and traffic lights to achieve avoidance between car transport AGVs, people, and vehicles. At the same time, it controls the AGV's emergency stop / resumption of movement through the AGV scheduling system.

[0047] Preferably, the charging module communicates with the AGV scheduling system via TCP / IP protocol, wherein the charging module is the server and the AGV scheduling system is the client; the charging module adopts an intelligent charging station with automatic retraction function.

[0048] Preferably, when the AGV meets the conditions for automatic charging, the AGV scheduling system sends a charging command to the car transport AGV, controls the car transport AGV to move to the charging station, and controls the car transport AGV to connect with the intelligent charging station; after the AGV scheduling system detects that the car transport AGV is connected to the intelligent charging station, it sends a start charging command to the charging station; when the car transport AGV's power meets the conditions for continuing to work, it sends a stop charging command to the charging station; after the car transport AGV has completed charging, it can transfer newly produced cars or move them to a designated address for standby according to the instructions of the AGV scheduling system.

[0049] Preferably, the parking space induction coil is laid on the parking space. In this embodiment, parking space induction coils are laid on all parking spaces. The parking space induction coil is used to sense whether there is a car parked in the parking space. When there is a car parked in the parking space, the parking space induction coil outputs a high level, and vice versa. The parking space induction coil is connected to a wireless communication system and establishes a communication connection with the AGV scheduling system through the wireless communication system to send information about whether there is a vehicle parked in the parking space to the AGV scheduling system.

[0050] Preferably, the AGV scheduling system initializes all parking spaces based on whether there are vehicles parked in them, thus completing the initialization of the parking spaces in the scene map. That is, it marks whether there are vehicles parked in the parking spaces in the initial state in the scene map. After the AGV scheduling system completes the initialization of the parking spaces in the scene map, it determines whether there are vehicles parked in the parking spaces by updating the data of newly produced vehicles in real time. There is no need to obtain the parking space status from the parking space induction coil, which improves the system operating efficiency.

[0051] Preferably, GPS is used to locate key points in the scene, such as the origin of the parking space in the receiving area, the center of the parking space in the garage area, the charging station in the charging module, and intersections, turning points, etc. in the road system. The coordinates are then converted into coordinates in the geodetic coordinate system through coordinate transformation calculation, and a scene map is built based on the geodetic coordinates of each key point.

[0055] Specifically, the attitude measurement system, car handling AGV, AGV scheduling system, vehicle-road cooperative system, charging module, parking space induction coil and wireless communication system are started and initialized to ensure that the control system is in normal working condition and that the communication connection of each module in the control system is guaranteed without any faults or alarms; the AGV scheduling system initializes the parking spaces in the scene map according to the status of the parking space induction coil and marks the parking status of the vehicles in each parking space.

[0056] S2: Newly produced cars are manually parked in the receiving area parking spaces;

[0057] Specifically, newly produced cars are driven manually from the production line to the receiving area, and parked within the parking space lines in the receiving area. The steering wheel is straightened so that the wheels are level with the car body before the driver gets off.

[0058] S3: Newly produced vehicle pose measurement system;

[0059] Specifically, firstly, a manual barcode scanner is used to scan the VIN of the newly produced vehicle to obtain the VIN; then, a binocular camera and a 600-line LiDAR are activated to scan the newly produced vehicle parked in the receiving area to obtain the position and pose information of the newly produced vehicle, and the obtained position and pose information of the newly produced vehicle is transmitted to the AGV scheduling system through a wireless communication system.

[0060] The attitude measurement of the newly produced car specifically includes the following steps:

[0061] S301: Start the attitude measurement system;

[0062] S302: The attitude measurement system receives the vehicle identification number (VIN) of the newly produced vehicle sent by the barcode scanner, and retrieves the vehicle model data of the newly produced vehicle from the vehicle manufacturer's database based on the vehicle feature information in the VIN.

[0063] S303: The attitude measurement system takes pictures of the side of the newly produced car using a binocular camera to generate a 2D image, and obtains wheel information and the relative relationship between the parked vehicle and the parking space frame. The wheel information includes the coordinates of the center point of the tire in the parking space coordinate system of the receiving area, the diameter, and the wheelbase. The attitude measurement system scans the newly produced car using a 600-line lidar to generate point cloud data of the scanned part.

[0064] S304: The attitude measurement system uses the least squares method to fit the point cloud data obtained in step S303 and the vehicle model data obtained in step S302 to obtain the point cloud data model of the newly produced car. The point cloud data model is the three-dimensional model of the newly produced car.

[0065] S305: The attitude measurement system uses OpenCV and YOLO_V5 algorithms to extract key feature points of the vehicle body from the wheel information obtained in step S303 and the three-dimensional model of the newly produced car obtained in step S304. The key feature point is the outermost point above the wheel hub, and the relative positional relationship between this point and the center point of the vehicle is fixed and known.

[0066] S306: Calibrate the coordinates of the key feature points in the parking space coordinate system of the receiving area. Simultaneously, calculate the coordinates of the vehicle center point in the parking space coordinate system of the receiving area through the positional relationship between the key feature points and the vehicle center point. Further, obtain the coordinates of the vehicle center point in the geodetic coordinate system through coordinate transformation calculation. The coordinate transformation calculation is as follows:

[0067] 1) Formula for calculating the geodetic coordinates of the origin of the parking space coordinate system in the receiving area:

[0068] X = ABS(Longitude of the geodetic origin - Longitude of the origin of the parking space coordinate system in the receiving area) / 180 * PI * 4893392.21998274

[0069] Y = ABS(latitude of geodetic origin - latitude of parking space coordinate system origin) / 180 * PI * 6371000

[0070] 2) Formula for calculating the geodetic coordinates of the vehicle center:

[0071] X = Geodetic coordinates of the origin of the parking space in the receiving area + X coordinates of the key feature points in the parking space coordinate system of the receiving area + A;

[0072] Y = Geodetic coordinates of the origin of the parking space in the receiving area + Y-coordinate of the key feature point in the parking space coordinate system of the receiving area + B;

[0074] S307: The pose information of the newly produced vehicle obtained in steps S302 to S306 is transmitted to the AGV scheduling system through a wireless communication system. The pose information includes the coordinates of the vehicle center in the geodetic coordinate system and the vehicle model information. The data format of the pose information is (X; Y; θ; CarWheelbase; VIN), where X, Y, and θ are the coordinates of the center point of the newly produced vehicle in the geodetic coordinate system, CarWheelbase is the wheelbase of the newly produced vehicle, VIN is the vehicle identification number (VIN) of the newly produced vehicle, and θ is the angle between the line connecting the center point of the newly produced vehicle and the origin of the parking space coordinate system in the receiving area and the Y-axis of the parking space coordinate system in the receiving area.

[0075] S4: Modify the scene map;

[0076] Specifically, the AGV scheduling system dynamically modifies the coordinates of the corresponding point in the scene map based on the pose information of the newly produced vehicle sent in step S3, that is, it synchronizes the geodetic coordinates of the center point of the newly produced vehicle to the corresponding receiving position in the scene map.

[0078] Specifically, the AGV scheduling system receives transfer task orders from the production management system, plans transfer routes based on currently available car transport AGVs, registers the planned transfer routes in the AGV scheduling system, and locks the transfer route resources.
