[0017] This application provides an intelligent integrated loading and unloading control system for plastics, which solves the technical problems of low accuracy and efficiency in the loading and unloading control of plastics in the prior art, resulting in unstable product quality. It achieves the technical effect of realizing efficient and automated loading and unloading of materials on plastic production lines, improving control accuracy and efficiency, and thus improving product quality and production safety.
[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0019] Example 1, as Figure 1As shown, this application provides an intelligent integrated loading and unloading control system for plastics, the system comprising: The material identification and positioning module 11 is used to acquire the loading and unloading robot. The loading and unloading robot integrates a vision sensor, a laser sensor, a locator, and a weight sensor. The loading and unloading robot identifies and positions the plastic materials on the target production line and acquires multi-dimensional characteristic parameter information of the plastic materials.
[0020] like Figure 2 As shown, furthermore, the step of obtaining multidimensional characteristic parameter information of plastic materials in this application also includes: The visual sensor captures images of the plastic material to obtain visual image information, while the laser sensor collects laser point cloud data of the plastic material. The visual image information and the laser point cloud data are spatially registered and fused to generate a visual model of the plastic material. Multidimensional parameters are extracted from the visual model to obtain plastic appearance feature parameters, including shape, size, and orientation. The locator and weight sensor are used to identify and perceive these appearance feature parameters to obtain plastic positioning information and plastic weight parameters. Based on the appearance feature parameters, positioning information, and weight parameters, multidimensional characteristic parameters of the plastic material are determined.
[0021] Furthermore, the step of generating the visualization model of the plastic material in this application also includes: Edge feature recognition is performed on the visual image information of the plastic material to determine the edge contour information of the plastic material. The laser point cloud data information is then filtered and denoised using the edge contour information of the plastic material to obtain usable plastic point cloud data information. Based on the edge contour information of the plastic material, key feature points are extracted from the visual image information of the plastic material to obtain a set of key feature points of the plastic material. Feature point mapping is then performed on the usable plastic point cloud data information according to the set of key feature points of the plastic material to obtain a set of key feature points of the plastic material point cloud. The set of key feature points of the plastic material and the set of key feature points of the plastic material point cloud are then registered and spatially aligned and fused to generate the visualization model of the plastic material.
[0022] Specifically, to achieve efficient and automated material loading and unloading on the plastic production line, a material identification and positioning module 11 is used to acquire a loading and unloading robot. This module is a functional module for omnidirectional feature recognition and positioning of the plastic materials. The loading and unloading robot can perform loading and unloading operations on plastic materials, improving the accuracy of loading and unloading. The robot integrates multiple sensors, including vision sensors, laser sensors, locators, and weight sensors. The loading and unloading robot identifies and positions the plastic materials on the target production line. First, the vision sensor captures images of the plastic materials. The vision sensor can preferably be an industrial camera, which acquires the corresponding visual image information of the plastic materials. Simultaneously, the laser sensor emits laser pulses to acquire laser point cloud data information of the plastic materials.
[0023] Spatial registration and fusion are performed on the visual image information of the plastic material and the laser point cloud data. First, edge feature recognition is performed on the visual image information of the plastic material using edge detection operators such as Canny and Sobel. The results of the edge detection algorithm determine the edge contour information of the plastic material, which describes the shape boundary of the plastic material in the two-dimensional image. The laser sensor may be affected by environmental noise, equipment errors, and other factors when acquiring point cloud data, generating unnecessary noise points. Therefore, the laser point cloud data is filtered and denoised using the edge contour information of the plastic material. By comparing and matching with the contour information, point cloud data that clearly does not belong to the plastic material contour can be removed, resulting in more accurate usable plastic point cloud data. Based on the edge contour information of the plastic material, key feature points are extracted from the visual image information of the plastic material to obtain a corresponding set of key feature points. These feature points are usually important nodes describing the shape and properties of the plastic material, such as corners and intersections. According to the position of the set of key feature points in the visual image, corresponding feature point mapping and extraction are performed on the usable plastic point cloud data to obtain the corresponding set of key feature points for the plastic material point cloud. The key feature point set of the plastic material and the key feature point set of the plastic material point cloud are registered. The optimal transformation parameters (such as rotation and translation) between the two datasets are found through data registration, ensuring they are aligned in the same coordinate system. After data registration, the visual image information and laser point cloud data are spatially aligned and fused. A 3D modeling technique is then used to generate a visual model of the plastic material that integrates the image and point cloud information, accurately reflecting the shape, size, and surface features of the plastic material.
[0024] Multidimensional parameters are extracted from the visualized model of the plastic material to obtain corresponding plastic appearance feature parameters, including shape, size, and distribution direction. The locator and weight sensor identify and perceive these plastic appearance feature parameters to obtain corresponding plastic positioning and weight parameters. Based on the plastic appearance feature parameters, positioning information, and weight parameters, multidimensional characteristic parameters of the plastic material are comprehensively determined. This enables comprehensive feature monitoring of the plastic material, providing a basis for subsequent loading and unloading control, thereby improving the accuracy and efficiency of plastic material control.
[0025] The control planning and analysis module 12 is used to collect and acquire the plastic material control database, perform traversal analysis based on the multi-dimensional characteristic parameter information of the plastic material and the plastic material control database, determine the target loading and unloading control parameters, and simultaneously monitor and acquire the production line characteristic parameter information. The module then performs path planning based on the production line characteristic parameter information and the multi-dimensional characteristic parameter information of the plastic material to determine the loading and unloading movement path information.
[0026] Furthermore, the step of determining the target loading and unloading control parameters in this application also includes: Based on the plastic material control database, multidimensional characteristic parameter information of historical plastic materials and corresponding loading and unloading control parameters are obtained; based on the multidimensional characteristic parameter information, the plastic material control database is segmented and integrated to obtain a plastic calibration control database; the multidimensional characteristic parameter information of plastic materials is matched and analyzed with the plastic calibration control database to obtain a plastic characteristic matching degree set; based on the plastic characteristic matching degree set, the plastic calibration control database is optimized and adjusted to determine the target loading and unloading control parameters.
[0027] Furthermore, the step of determining the target loading and unloading control parameters in this application also includes: Based on the plastic property matching degree set, the plastic calibration control database is optimized to determine matching loading and unloading control parameters; the multidimensional feature parameter information is used as independent variables, and the loading and unloading control parameters are used as dependent variables in sequence for regression fitting to generate a set of loading and unloading feature parameter regression curves; the regression curves in the set of loading and unloading feature parameter regression curves are correlated and fused to generate a loading and unloading feature parameter correlation model; based on the loading and unloading feature parameter correlation model, the matching loading and unloading control parameters are calculated and optimized to determine the target loading and unloading control parameters.
[0028] Specifically, the control planning and analysis module 12 collects and acquires a plastic material control database. This module is a functional module used for precise analysis of the loading and unloading control parameters and control paths of plastic materials. The plastic material control database contains historical loading and unloading control parameters for various types of plastic materials. A comprehensive analysis is performed based on the multi-dimensional characteristic parameter information of the plastic materials and the plastic material control database. The specific analysis process is as follows: First, based on the plastic material control database, multi-dimensional characteristic parameter information of historical plastic materials and corresponding loading and unloading control parameters such as loading and unloading speed, angle, direction, and force are obtained. Then, based on the multi-dimensional characteristic parameter information, the plastic material control database is feature-divided and integrated, grouping data with the same multi-dimensional characteristic parameter information type into one category to obtain the integrated plastic calibration control database. A similarity algorithm is used to match and analyze the multi-dimensional characteristic parameter information of the plastic materials with the plastic calibration control database, obtaining the similarity calculation results between the control data of each type of plastic in the plastic calibration control database and the multi-dimensional characteristic parameter information of the plastic materials. The similarity calculation results are then used as a plastic characteristic matching degree set.
[0029] The plastic calibration control database is optimized based on the plastic property matching degree set. First, the database is optimized using the plastic property matching degree set to determine the parameter with the highest matching degree as the matching loading and unloading control parameter. Then, the multidimensional feature parameter information is used as the independent variable, and each type of control parameter in the matching loading and unloading control parameters is used as the dependent variable for regression fitting, generating a corresponding set of loading and unloading feature parameter regression curves. These curves describe the functional relationship between different multidimensional feature parameters and each loading and unloading control parameter. The regression curves in the loading and unloading feature parameter regression curve set are correlated and fused using neural networks or similar methods to generate a comprehensive loading and unloading feature parameter correlation model. This model is used to analyze the loading and unloading control parameters based on the multidimensional feature parameters. Since the multidimensional feature parameter information corresponding to the matching loading and unloading control parameters may not be completely matched, resulting in feature deviation, the feature deviation of the matching loading and unloading control parameters is calculated and optimized based on the loading and unloading feature parameter correlation model. The optimized values of the loading and unloading control parameters are output, thereby determining the optimized target loading and unloading control parameters considering the feature deviation.
[0030] Simultaneously, the production line control system monitors and acquires characteristic parameter information of the production line. This characteristic parameter information includes production line status parameters, such as equipment operating status, distribution, dimensional parameters, production speed, and production line load. Multiple path planning algorithms are used to plan paths based on the production line characteristic parameter information and the multi-dimensional characteristic parameters of the plastic material, determining the optimal loading and unloading motion path. This achieves optimized analysis of plastic loading and unloading control parameters while ensuring the safe and efficient movement path of the robot, thereby improving the efficiency of plastic material loading and unloading and product quality.
[0031] Furthermore, the step of determining the loading and unloading movement path information in this application also includes: Based on the production line characteristic parameter information, a graph representation is performed to generate a loading / unloading production line map. Obstacles are marked on the loading / unloading production line map to determine loading / unloading constraint information. The loading / unloading optimization objective is obtained, evaluated, and fitted to generate a loading / unloading fitness function. Based on the loading / unloading constraint information, a path search is performed within the loading / unloading production line map using a list of path planning algorithms to obtain a set of planned loading / unloading paths. The loading / unloading fitness function is then used to compare and optimize the set of planned loading / unloading paths to determine the loading / unloading movement path information.
[0032] Furthermore, the step of generating the loading and unloading production line map in this application also includes: The production line feature parameter information is used to identify and mark objects to obtain a set of production line distributed objects. The set of production line distributed objects is then abstracted as a set of graph model nodes. The graph model node set is then marked with path attributes according to the production line feature parameter information to obtain a set of graph model connecting edges. A topological graph representation is then performed based on the graph model node set and the graph model connecting edge set to generate a map of the loading and unloading production line.
[0033] Specifically, the planning of the loading and unloading movement path for plastic materials is as follows: Based on the production line characteristic parameter information, a graph representation is created to achieve rapid path visualization and planning. First, object recognition and labeling of the production line characteristic parameter information is performed through image recognition. This information includes the location, size, type, and function of equipment, resulting in a corresponding set of production line distributed objects, including equipment and plastic materials. Then, each object in the production line distributed object set is abstracted as a node in a graph model, and node attributes are identified based on node location, size, and other information, thus obtaining a graph model node set. According to the node distribution distance, material flow path, and path complexity of the production line characteristic parameter information, path attribute identification is performed between the nodes in the graph model node set, obtaining a set of graph model connection edges between each node. Based on the graph model node set and the graph model connection edge set, a topology graph representation is created. In the topology graph, nodes represent various objects on the production line, and connection edges represent the path relationships between objects, generating a corresponding loading and unloading production line map to more intuitively display the layout and path relationships of the production line.
[0034] Obstacles are marked on the loading / unloading production line map. These obstacles may include fixed machinery, transport tracks, safety zones, etc., which limit the movement range of the loading / unloading robots and are identified as loading / unloading constraints. Loading / unloading optimization objectives are obtained, typically including factors such as efficiency, cost, and safety, for example, minimizing loading / unloading time, minimizing energy consumption, or maximizing production line throughput. Weights are assigned to each objective in the loading / unloading optimization objectives according to the loading / unloading requirements of the plastic materials. Then, a multivariate evaluation fitting is performed on the loading / unloading optimization objectives based on the weight allocation results to generate a loading / unloading fitness function. This fitness function is used to evaluate the merits of different paths; a higher fitness indicates a better path performance. A list of path planning algorithms is compiled based on the optimization objectives. This list includes various algorithms such as A* algorithm, Dijkstra's algorithm, genetic algorithm, and particle swarm optimization algorithm. Based on the loading / unloading constraints, path searches are performed within the loading / unloading production line map according to each path planning algorithm in the list, obtaining a set of optimized loading / unloading paths for each algorithm. Then, the loading / unloading fitness function is used to evaluate and compare the set of planned loading / unloading paths to find the best path. The path with the highest fitness is then selected as the loading / unloading path information to maximize the optimization goal while satisfying all constraints. By using a multi-path planning algorithm to optimize loading / unloading paths, the rationality and accuracy of path planning are improved, thereby increasing loading / unloading production efficiency and product quality.
[0035] The loading and unloading execution module 13 is used to perform loading and unloading control on the plastic material by the loading and unloading robot based on the target loading and unloading control parameters and the loading and unloading motion path information, and to monitor the execution process in real time and obtain loading and unloading execution parameter information.
[0036] Specifically, the loading / unloading execution module 13 is used to control the loading / unloading robot to perform loading / unloading control operations on the plastic material based on the target loading / unloading control parameters and the loading / unloading motion path information, and to monitor the execution process in real time to obtain loading / unloading execution parameter information. The loading / unloading execution parameter information is loading / unloading status feedback parameters, including loading / unloading position, speed, and robot control status, etc., to provide optimization basis for subsequent loading / unloading execution parameters, so as to improve the accuracy and timeliness of loading / unloading control.
[0037] The feedback optimization analysis module 14 is used to identify anomalies in the loading and unloading execution parameter information, obtain abnormal loading and unloading feature parameters, perform optimization analysis based on the abnormal loading and unloading feature parameters, determine the loading and unloading execution optimization parameters, and perform integrated loading and unloading control through the loading and unloading execution optimization parameters.
[0038] Furthermore, the step of determining the optimization parameters for loading and unloading also includes: Based on the abnormal material loading and unloading characteristic parameters, an emergency strategy optimization analysis is performed to obtain multiple material loading and unloading optimization measures strategy parameter schemes; a material loading and unloading effect simulation module is constructed, and the multiple material loading and unloading optimization measures strategy parameter schemes are simulated and optimized based on the material loading and unloading effect simulation module to determine the material loading and unloading execution optimization parameters.
[0039] Specifically, the feedback optimization analysis module 14 is used to train historical data through machine learning to obtain an anomaly identification model. This model then identifies anomalies in the loading and unloading execution parameters, yielding corresponding loading and unloading anomaly characteristic parameters. These parameters include the type and severity of the anomaly, such as material misalignment, force control issues, and robot malfunctions. Emergency strategy optimization analysis is performed on these anomaly characteristic parameters using historical data of the plastic loading and unloading strategy to match targeted emergency strategies. Through this matching optimization analysis, multiple loading and unloading optimization measures and strategy parameter schemes are obtained, including adjusting loading and unloading speeds, optimizing loading and unloading paths, and improving force control algorithms.
[0040] A material handling effect simulation module is constructed using simulation software based on historical material handling data. This module can simulate and predict the actual material handling control state. Within the simulation module, parameters and conditions similar to the actual production environment are set. Multiple material handling optimization strategies and parameter schemes are simulated based on this module, and the material handling effects under different schemes, such as efficiency, accuracy, and energy consumption, are compared. Based on the simulation results, the optimal material handling execution optimization parameters are determined, and the selected scheme is further simulated, verified, and fine-tuned to ensure its effectiveness in actual production. Integrated material handling control is achieved through these optimized execution parameters, enabling continuous improvement and optimization of material handling control parameters, increasing control accuracy and efficiency, and ultimately improving product quality and production safety.
[0041] In summary, the intelligent integrated loading and unloading control system for plastics provided in this application has the following technical advantages: This technical solution employs a loading / unloading robot to identify and locate plastic materials on the target production line. It acquires multi-dimensional characteristic parameters of the plastic materials and analyzes them against a plastic material control database to determine target loading / unloading control parameters. Simultaneously, it monitors and acquires production line characteristic parameters, performs path planning based on these parameters, and determines the loading / unloading movement path. The loading / unloading robot then executes loading / unloading control based on these parameters and path information, with real-time monitoring of the process. Anomalies are identified in the execution parameters, and abnormal characteristic parameters are used for optimization analysis to determine optimized loading / unloading parameters for integrated control. This achieves highly efficient and automated loading / unloading on the plastic production line, improving control accuracy and efficiency, and ultimately enhancing product quality and production safety.
