[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0027] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0028] See also Figure 1 The present invention provides an AGV-based intelligent transformer handling method, comprising: S100 . In the process of controlling the AGV to move along a preset route, a camera module provided on the AGV is used to obtain a target image, and it is determined whether the target image includes at least two parallel load-bearing beams 2 .

[0029] Specifically, the load-bearing beam 2 is fixedly mounted on two identical transformer legs 1 , and the fixing method includes welding.

[0030] It can be understood that the preset route shown passes through the center lines of two parallel load-bearing beams 2, and then through the AGV-based intelligent transformer handling method designed by the present invention, precise intelligent handling of box-type transformers is achieved, which greatly improves the safety, reliability and intelligence of the intelligent handling of transformers.

[0031] Specifically, the camera module includes a high-definition industrial camera.

[0032] Specifically, the preset route is pre-planned and set by the control module of the AGV.

[0033] Specifically, in step S100, the target image is an image of a scene within a certain range in front of the AGV.

[0034] It should be further explained that, regarding step S100, the solution designed by the present invention specifically includes: Camera module configuration: A 20-megapixel high-definition industrial camera (such as the Basler ac A2000) with a frame rate of 30 fps is installed at the front of the AGV at a height of 1.2 m and a depression angle of 15°.

[0035] Image recognition threshold: Parallelism threshold of load-bearing beam: ≤3° (angle between two beam axes); Minimum recognition size: beam width ≥ 50 pixels (based on 5m recognition distance).

[0036] Preferred value reasons: 30fps frame rate avoids motion blur; 15° depression angle covers 3-5m field of view in front of the AGV; 3° parallelism threshold ensures horizontal error of the load-bearing plane is less than 5mm / m.

[0037] S200: If two parallel load-bearing beams 2 are identified, the three-dimensional posture of each load-bearing beam 2 is identified based on image processing; and based on the three-dimensional posture data of the two load-bearing beams 2, the posture of the load-bearing plane formed by the two load-bearing beams is calculated.

[0038] Specifically, in step S200, a three-dimensional vision algorithm is used to identify the three-dimensional position and posture of the load-bearing beam 2.

[0039] Specifically, in step S200, the posture of the load-bearing plane is calculated by the least squares method.

[0040] It should be further explained that, regarding step S200, the solution designed by the present invention specifically includes: 1. Design algorithm process: ① Feature point extraction: Use SIFT algorithm to detect the corner points of load-bearing beams ; ② Posture solution: Design the following formula to solve the PnP problem: in: is the scale factor, used to align the secondary coordinates for normalization; Camera intrinsic parameter matrix; Rotation and translation matrices; World coordinates of the corner points of the load-bearing beam; is the image pixel coordinate, is the horizontal pixel coordinate of the target point in the image (increasing from left to right), is the vertical pixel coordinate of the target point in the image (increasing from top to bottom), 1 is the normalization term for homogeneous coordinates (fixed to 1).

[0041] ② Load-bearing plane fitting: The least squares method is used to fit the plane equation: ; in: plane normal vector is the posture direction, is a constant term that determines the distance from the load-bearing plane to the origin of the coordinate system; x, y, and z are the three-dimensional coordinate values ​​of any point in space, and their physical meaning is the position component of the point in the selected coordinate system. Specific to the implementation scenario of this patent: Coordinate system definition: The camera coordinate system or the world coordinate system is used as the reference (the world coordinate system is established with the initial position of the AGV as the origin).

[0042] x-axis: The horizontal direction pointing to the direction of AGV travel (forward direction is +X).

[0043] Y-axis: The direction perpendicular to the x-axis (left and right directions of the AGV).

[0044] z-axis: The direction perpendicular to the horizontal plane (height direction, positive upward).

[0045] a, b, c: The coefficients of the plane equation, forming the plane normal vector n = (a, b, c). The direction of the normal vector is perpendicular to the load-bearing plane, and its modulus |n| is related to the distance from the plane to the origin.

[0046] Parameter optimization: Number of iterations: 100 (balance between accuracy and real-time performance); Reprojection error threshold: ≤1.5 pixels (guaranteed pose accuracy ±2mm).

[0047] The following is a specific example to illustrate: Assume that the coordinates of three points on the load-bearing beam are detected (unit: mm): Point 1: (1000, 500, 200); Point 2: (1200, 500, 205); Point 3: (1000, 700, 198); The plane equation is obtained by least squares fitting: 0.002x−0.001y+0.999z−199.8=0; but: Normal vector =(0.002,−0.001,0.999), basically vertically upward; The plane height is ≈ 200 mm (0.0022+(−0.001)²+0.9992|199.8|≈200).

[0048] Technical value: By solving the plane equation, the AGV can accurately obtain: The horizontal inclination of the load-bearing plane (determined by the direction of the normal vector); The target height for transformer placement (derived from the constant term d); The spatial orientation of the support structure (reflected by the x,y coefficients); Ultimately, transformer placement with an accuracy of ±2mm is achieved.

[0049] S300: Based on the posture of the load-bearing plane, control the AGV to accurately place the transformer on the load-bearing plane, and automatically retreat along a preset route after completion.

[0050] Specifically, in step S300, the AGV determines its own position through its own positioning system to achieve precise placement.

[0051] Specifically, after the AGV automatically retreats, it sends a transport completion message to the remote monitoring terminal.

[0052] It should be further explained that, regarding step S300, the solution designed by the present invention specifically includes: The motion control parameters are shown in Table 1: Table 1 Motion control parameters Return process: After the AGV releases the transformer, it retreats along the preset Bezier curve path; Real-time monitoring of the distance from the load-bearing beam: safety threshold ≥ 0.5m; Upon reaching the safety point, a completion signal is sent to the monitoring terminal.

[0053] It should be noted here that the methods for designing the Bezier curve retreat path include: 1. Path control point definition: Control point selection rules (AGV current position as the starting point P0, safety point as the end point P3): P1: 0.5m behind the starting point P0 (coordinates (x0, y0-0.5), avoid sharp turns); P2: 0.3m in front of safety point P3 (coordinates (x3, y3+0.3), ensuring smooth path access to the end point); Bezier curve equation: cubic Bezier curve parametric equation (t∈[0,1]): in: B(t) represents the precise position coordinates of the AGV at any time t on the retreat path; P0: coordinates of the AGV when it releases the transformer (obtained in real time by the AGV positioning system); P3: Safety point coordinates (preset in the control system map).

[0054] 2. Path generation parameters are shown in Table 2: Table 2 Path generation parameters 3. Dynamic obstacle avoidance strategy Real-time path correction: If the LiDAR detects an obstacle (such as a person or equipment) on the path, the control point is updated according to the following rules, using the detection window of 1m in front: New P2'=P2+Δd· (Δd is the obstacle avoidance distance, is the obstacle normal vector); Constraints: The total path length changes by ≤10%, and the curvature radius remains ≥2m.

[0055] It should be noted here that the methods for real-time monitoring of the distance from the load-bearing beam include: 1. Sensor configuration is shown in Table 3: Table 3 Sensor configuration 2. Design distance fusion algorithm: ①Data preprocessing: Perform plane fitting on the LiDAR point cloud, extract the plane equation where the load-bearing beam 2 is located, and calculate the Euclidean distance from the AGV tail to the plane : in: is the coordinate of the center of the AGV tail in the laser radar coordinate system; a, b, and c are the normal vector coefficients of the load-bearing plane.

[0056] ②Multi-sensor weighted fusion: in: The distance measured by the lidar is a high-precision result based on point cloud plane fitting; The distance measured by ultrasonic wave; The weight is dynamically adjusted based on the sensor confidence level. 0.7 is determined by a confidence level of 0.9, and 0.3 is determined by a confidence level of 0.7 (LiDAR confidence level = 0.9, Ultrasonic wave confidence level = 0.7). is the final distance after fusion; ③ Dynamic weight adjustment rules (illustrated in the figure): When the lidar confidence drops to 0.8: the weight is adjusted to 0.65; When the ultrasonic confidence level rises to 0.8: the weight is adjusted to 0.35.

[0057] 3. Design a dynamic adjustment plan for security thresholds Basic threshold: 0.5m (static safety margin); Speed ​​compensation: in: is the dynamic safety threshold; 0.5 is the preferred basic safety threshold of the present invention; 0.1 is the speed compensation coefficient.

[0058] Example: If the AGV moves backward at 0.2 m / s, .

[0059] Physical meaning: Braking distance = v × t 响应=0.2×0.2=0.04m; After compensation, the threshold value is 0.52m = 0.5m (static) + 0.02m (dynamic margin).

[0060] It is understood that the method further comprises: Control Decisions: when :AGV returns normally; when : Triggering the third level brake: Level 1: deceleration to 0.1m / s (distance threshold 0.51m); Level 2: shutdown alarm (distance threshold 0.50m); Level 3: Mechanical brake (distance threshold 0.48m).

[0061] Technical advantages: Through the fusion algorithm (weight 0.7 / 0.3) and dynamic threshold (coefficient 0.1), when the maximum AGV retraction speed is 0.3m / s: False trigger rate <0.1% (compared to 2.3% for traditional fixed threshold scheme); The braking distance is shortened by 40% (0.06m vs 0.10m).

[0062] It is understood that the present invention has the following beneficial effects: 1. Methodology 1. High-precision posture recognition: Industrial cameras and three-dimensional vision algorithms are used to dynamically identify the characteristic points of the load-bearing beams, and the least squares method is used to fit the load-bearing plane to eliminate manual measurement errors and ensure that the transformer placement accuracy reaches the millimeter level.
