Description
A parallel lifting transplanting and conveying device and method thereof Technical Field
[0001] This invention relates to the field of conveying equipment and system control technology, specifically to a parallel lifting transplanting conveying equipment and method thereof. Background Technology
[0002] Lifting and transferring machines are mainly used to change the direction of goods transport, moving items from forklifts into or out of the main conveyor line. They are characterized by high load capacity, simple structure, and stable reliability. However, existing lifting and transferring machines still have some problems. Lifting and transferring machines are required to achieve fast and efficient lifting operations, ensure the stability and reliability of the transport process, and simultaneously consider the equipment's service life and maintenance costs.
[0003] With the rapid development of industrial production, mechanical equipment is developing towards intelligence, complexity, automation, precision, and high speed. The connections between various components are becoming closer, and coupled with their complex working environment, mechanical equipment is prone to failure and is difficult to operate and maintain.
[0004] Traditional fault diagnosis techniques include expert systems, model analysis, and signal processing. However, these methods suffer from drawbacks such as poor versatility, complex modeling, weak robustness, and poor representation capabilities, severely limiting their application. In fault diagnosis, sensor data is singular, and the converted image data is also acquired separately by each sensor, thus failing to reflect all the characteristics of the fault from multiple perspectives. Data-level information fusion ensures the integrity of the original information. Therefore, data fusion from multiple sensors is of great significance for fault diagnosis.
[0005] Currently, some methods based on digital twin technology have been applied to equipment fault diagnosis and prediction. However, traditional methods for creating data twins lack the ability to deeply analyze complex data and environmental changes, making it difficult to accurately capture and reflect performance changes under complex environmental conditions, thus affecting prediction accuracy and system responsiveness. Furthermore, existing predictive maintenance systems still need improvement in classification accuracy and processing efficiency when handling large amounts of unlabeled fault data. Therefore, there is an urgent need for an intelligent monitoring and control system that can integrate multi-source sensor information, improve fault diagnosis accuracy, and achieve predictive maintenance.
[0006] Traditional fault diagnosis techniques have poor versatility, complex modeling, weak robustness, and poor characterization capabilities, making it difficult to accurately reflect performance changes under complex environmental conditions, which affects prediction accuracy and system response capabilities.
[0007] The existing distributed tension monitoring network still has issues with sensor layout and data transmission methods that need further optimization, affecting the accuracy and real-time performance of the data.
[0008] Current predictive maintenance systems still need to improve classification accuracy and processing efficiency when dealing with large amounts of unlabeled fault data, and struggle to achieve in-depth analysis capabilities for complex data and environmental changes.
[0009] Existing intelligent monitoring and control systems lack an effective fusion mechanism for multi-source heterogeneous data, and cannot fully utilize the advantages of each sensor, resulting in insufficient accuracy and comprehensiveness in fault diagnosis.
[0010] Traditional fault prediction models lack the ability to dynamically adjust the operating status of equipment, making it difficult to adapt to complex and ever-changing operating environments and unable to effectively extend equipment lifespan and reduce maintenance frequency.

[0078] I. Construction of a High-Precision Digital Model for the Nonlinear Characteristics of Belt Materials
[0079] This invention employs a hyperelastic constitutive model to describe the large deformation nonlinear characteristics of belt materials, using the Mooney-Rivlin model, whose strain energy density function is:
[0080]
[0081] in:
[0082] —Material property parameters were obtained through uniaxial tensile testing and least squares fitting.
[0083] —The first and second strain invariants;
[0084] —Volume strain, when the belt is approximately incompressible ;
[0085] — Volume compressibility factor.
[0086] If the belt exhibits significant creep (plastic deformation under long-term load), a Burger creep model correction is applied:
[0087]
[0088] in For the elastic modulus component, The relaxation time constant is calibrated through long-term creep tests under different loads.
[0089] Introducing the temperature-load-wear multi-field coupling factors, a correction coefficient matrix is established:
[0090] Temperature correction: Real-time belt temperature is collected via thermocouples, and the elastic modulus is established based on experimental data. The functional relationship with temperature is embedded in the constitutive model;
[0091] Wear correction: By combining belt mileage and surface wear monitoring data, the belt cross-sectional area and friction coefficient are corrected, which affects the tension transmission efficiency;
[0092] Load distribution correction: Real-time loads in different sections of the belt are collected by distributed tension sensors and used as boundary conditions for the model.
[0093] The belt is discretized into n infinitesimal segments along its length. Each infinitesimal segment is considered as an independent nonlinear spring-damped element. The overall dynamic equations are constructed using the finite element method (FEM).
[0094]
[0095] in It is a nonlinear stiffness matrix that changes in real time with the strain of the micro-element. This is the external excitation force for the drive wheel and tensioner wheel.
[0096] A parameter identification and optimization model driven by real-time data is used: tension and strain monitoring data during belt operation are used to iteratively correct the model using a particle swarm optimization (PSO) algorithm. By controlling core parameters such as these, the model can achieve online self-calibration.
[0097] II. GPU-accelerated real-time tension distribution simulation calculation
[0098] Utilizing a CPU-GPU heterogeneous computing model, acceleration strategies are optimized:
[0099] Mesh partitioning parallelism: The discretized belt micro-segments are distributed to multiple thread blocks of the GPU, with each thread responsible for solving the dynamic equations of one micro-segment, utilizing the parallel computing capabilities of the GPU's massive cores;
[0100] Sparse matrix optimization: Nonlinear stiffness matrix As a sparse matrix, it adopts the CSR (Compressed Sparse Row) storage format to reduce memory usage and improve computational efficiency;
[0101] Iterative solver selection: The conjugate gradient method (CG) or GMRES algorithm is selected to solve the nonlinear equation system. Compared with direct solvers (such as LU decomposition), the computational efficiency is improved by 1 to 2 orders of magnitude, which meets the real-time requirements (single solution time <10ms).
[0102] Real-time simulation process;
[0103] 1. The CPU receives data such as belt speed, temperature, and initial tension from the sensors, which are used as input boundary conditions for the GPU simulation.
[0104] 2. The GPU loads the latest nonlinear constitutive model parameters, solves the dynamic equations in parallel, and outputs the predicted value of the tension distribution in the entire segment;
[0105] 3. The GPU sends the prediction results back to the CPU to complete one simulation cycle. The cycle can be set according to actual needs (50~100ms recommended).
[0106] III. Real-time data comparison of the central controller and pre-adjustment of the tensioning mechanism
[0107] Employing industrial-grade PLCs or embedded controllers, the architecture is divided into three layers:
[0108] Sensing layer: Receives real-time data from tension sensors, temperature sensors, and encoders;
[0109] Decision-making level: Compare the model-predicted tension with the measured tension, and calculate the deviation value. ;
[0110] Execution layer: Outputs tensioning mechanism adjustment commands based on deviation values.
[0111] Feedforward pre-adjustment: Based on the tension change trend predicted by the GPU (such as a sudden increase in tension during the startup phase or a decrease in tension before a sudden load change), the tension command is output in advance to suppress the source of tension fluctuations;
[0112] Compare the deviations between predicted and measured values ,like Initiate PID feedback regulation to correct the error of feedforward control;
[0113] PID control law: ,in This is the adjustment amount for the tensioning mechanism.
[0114] This technical solution has small tension prediction error, high real-time performance and adaptability. Data-driven parameter identification enables the model to automatically optimize as the belt ages and working conditions change, maintaining high accuracy over a long period.
[0115] Multi-belt synchronization control module: For multi-belt systems, vision-based real-time monitoring of belt running trajectory is adopted, combined with differential speed compensation algorithm to ensure that the multi-belt system maintains synchronization accuracy of ±0.5mm when running at high speed; real-time data processing and optimization are realized through central controller.
[0116] This solution uses machine vision technology to collect and analyze the running trajectory parameters of each belt in real time, providing a precise data source for subsequent compensation. Addressing the speed coupling characteristics of multi-belt systems, a differential speed compensation algorithm is employed to offset synchronization errors caused by trajectory deviations through real-time speed adjustment of each belt drive motor.
[0117] Let the first belt in a multi-belt system be... The real-time speed of the belt is The base speed is The trajectory offset is Then the compensation speed The differential equation is:
[0118]
[0119] in:
[0120] This is a scaling factor used for fast response to static offset;
[0121] These are differential coefficients used to suppress abrupt changes in offset and avoid overcompensation.
[0122] The central controller receives offset data from the vision module. Substitute into the differential equation to solve for the real-time compensation speed Output speed control command to the first The variable frequency drive device for the belt adjusts the motor speed to bring the belt track back to the baseline.
[0123] Central controller data processing and optimization:
[0124] Data acquisition layer: Receives trajectory data from each edge node and speed / tension sensor data from each belt in real time via industrial Ethernet (such as Profinet);
[0125] Operational Analysis Layer:
[0126] Run the differential speed compensation algorithm to generate speed control commands;
[0127] Establish a multi-belt synchronization accuracy evaluation model and calculate the overall system synchronization error. ;
[0128] Train machine learning on historical data and optimize , Parameters enable the algorithm to be adaptive.
[0129] Command sending layer: Sends speed control commands and abnormal alarm signals to the corresponding execution units (frequency converters, audible and visual alarms).
[0130] Data storage layer: Stores real-time operational data and historical fault information, supporting traceability analysis and report generation.
[0131] The Time-Sensitive Networking (TSN) protocol is adopted to ensure low latency (≤10ms) and high reliability of data transmission, meeting the real-time requirements of high-speed operation scenarios.
[0132] This solution can improve synchronization accuracy during high-speed operation, with strong real-time performance and good adaptability.
[0133] Fault prediction and maintenance decision-making module: Based on deep learning algorithms, it analyzes equipment vibration, temperature, and tension data to predict potential faults and automatically adjust operating parameters; it achieves high-speed data transmission through industrial-grade 5G networks and uses digital twin technology to build a virtual image, enabling equipment status visualization and parameter optimization; it deploys lightweight neural networks through edge computing units for local prediction, combined with cloud-based deep reinforcement learning models, to predict the remaining service life of the equipment; it uses Bayesian optimization algorithms to dynamically adjust maintenance thresholds and automatically generates optimal maintenance time windows and specific maintenance item lists based on equipment operating history and current production plans.
[0134] This solution, based on deep learning algorithms, constructs a feature extraction and correlation analysis model for multi-source sensor data such as equipment vibration, temperature, and tension. This model accurately identifies weak characteristic signals of early equipment failures, enabling early warning of potential malfunctions. Simultaneously, based on the fault warning level, the model automatically outputs optimized adjustment schemes for equipment operating parameters (such as speed, load, and pressure), and corrects the equipment's operating status in real time through a closed-loop control link, reducing the probability of failure.
[0135] Leveraging the high bandwidth and low latency of industrial-grade 5G networks, high-speed and stable transmission of multi-source sensor data is achieved. Based on digital twin technology, a virtual mirror image mapped 1:1 to the physical device is constructed, integrating the device's geometric model, operational mechanism model, and data-driven model, synchronizing the device's physical status and operating parameters in real time. Through the digital twin visualization platform, it supports 3D panoramic display of the device's operating status, trend analysis of key parameters, and fault tracing simulation. Simultaneously, parameter simulation experiments are conducted using the virtual mirror image to quickly find the optimal operating parameter range for the device and distribute it to the physical device.
[0136] Employing an edge-cloud collaborative computing architecture, we can achieve tiered and accurate prediction of the remaining lifespan of devices.
[0137] Edge side: Deploy lightweight neural networks (such as MobileNet and lightweight Transformer) within the edge computing unit to complete short-term health status assessment and preliminary RUL prediction of the device based on locally collected real-time sensor data, meeting the requirements of low latency and localized decision-making;
[0138] On the cloud side: Deploy a deep reinforcement learning (DRL) model, gather full lifecycle operation data and historical fault records from multiple similar devices, and build a global, high-precision RUL prediction model through trial and error and iterative optimization of reinforcement learning; the edge side and the cloud side achieve complementary integration of short-term and long-term predictions through lightweight updates and interactions of model parameters.
[0139] Based on Bayesian optimization algorithms, and combining historical equipment failure data, maintenance records, and current production schedules, the system dynamically adjusts maintenance thresholds (such as vibration and temperature thresholds) for equipment health status to avoid over- or under-maintenance. Simultaneously, using equipment RUL prediction results as the core input, and comprehensively considering constraints such as production task priority, maintenance resource scheduling costs, and downtime losses, the system automatically generates optimal maintenance time windows (such as production gaps and low-load periods) and a detailed maintenance item list (including spare parts to be replaced, maintenance procedures, and technical standards), achieving coordinated optimization of maintenance strategies and production plans.

[0157] Reset process: After the material transfer is completed, the control system commands the servo motor 30 to rotate forward, the cam mechanism drives the chassis 12 to descend smoothly to the initial position, the belt conveyor mechanism resumes operation, and enters the next work cycle.
