[0002] Hydraulic synchronous lifting technology is an advanced construction technique widely used for the overall lifting of large structures (such as steel structures, bridges, and roofs). Its core requirement is to ensure the stability of the lifted components and the precision of the lifting through multi-point coordinated control, avoiding safety accidents such as uneven stress, deformation, or even falling of components due to synchronous deviation of the lifting points.
[0003] Traditional hydraulic synchronous lifting systems typically combine computer control, electro-hydraulic proportional valves, sensor detection, and PID control algorithms to achieve synchronous lifting, load balancing, and attitude control across multiple lifting points. This traditional control system suffers from limitations such as strong parameter dependence, insufficient adaptive capability, weak predictive ability, outdated monitoring methods, and low levels of information technology. In recent years, large-scale AI models (such as Transformer, GPT series, and reinforcement learning models) have demonstrated significant potential in industrial control, enabling adaptive decision-making and predictive control through data-driven approaches.
[0004] The purpose of this invention is to overcome the shortcomings of existing synchronous lifting technologies and provide a large-model driven hydraulic synchronous lifting control system and method. By introducing the intelligent perception, prediction and decision-making capabilities of the large model, the control accuracy, adaptability, safety and intelligence level of the system under load conditions are improved.

[0035] Compared with the prior art, the present invention has at least one of the following advantages or beneficial effects:

It can accurately identify complex working conditions such as wind load interference and automatically optimize control strategies and parameters. It can effectively reduce the synchronous deviation of multiple lifting points and ensure the stability of the lifting process.

[0037] 2) Enhanced prediction and risk management capabilities: By using a high-fidelity virtual model built with a digital twin module for simulation and deduction, combined with the prediction function of the core decision-making big model, potential risks such as excessive synchronous deviation of lifting points, stress concentration of components, and hydraulic system failures can be detected in advance. Then, through the fault diagnosis function, early warnings can be issued in a timely manner and disposal solutions can be provided, which greatly improves construction safety.
[0038] 3) More convenient human-machine collaborative management: The human-machine interface can clearly display the system's operating status, decision-making basis, and early warning information.

[0044] Figure 3 This is a flowchart of the control method for a large-model-driven hydraulic synchronous lifting control system in an embodiment of the present invention. Detailed Implementation
[0045] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but these are not intended to limit the scope of the invention.
[0046] Example 1:
[0047] like Figure 1 As shown, this embodiment discloses a large-model-driven hydraulic synchronous lifting control system, including a hydraulic lifting execution cluster, a sensor network, edge computing and control nodes, a large-model intelligent decision-making center, and a human-machine interface. The connection relationships and functions of each component are as follows:
[0048] The hydraulic lifting execution cluster includes a cluster of lifting devices (specifically, multiple 350t lifting cylinders), a load-bearing system, a hydraulic pump station, and a valve group. It is used to receive control signals from edge computing and control nodes and execute the lifting and lowering operations (i.e., ascending and descending operations) of the lifted components. The hydraulic pump station provides hydraulic power to the system, and the valve group uses electro-hydraulic proportional valves to achieve precise speed control of each lifting device. The lifting devices work in conjunction with the load-bearing system through the extension and retraction of the cylinders to complete the stable lifting and lowering of the lifted components.
[0049] A sensor network is deployed within the lifted component and the hydraulic lifting actuator cluster to collect key status data in real time during the lifting process. This includes the current position of the lifting cylinder piston rod, the anchor tension status, the hydraulic pressure of the main lifting system, and the synchronous height difference signal at each lifting point. The collected real-time data (i.e., raw data) is transmitted to the edge computing and control node. Specifically, the sensor network includes a laser rangefinder, position switches, limit switches, and hydraulic pressure sensors. The laser rangefinder is deployed at each lifting point to collect the synchronous height difference. The position switches are deployed at the upper and lower anchor actuator ends to detect the anchor tension status. Multiple limit switches are equidistantly deployed at multiple points on the outside of the main lifting cylinder to collect the current position of the lifting cylinder piston rod. The hydraulic pressure sensors are deployed at the outlet of the electro-hydraulic proportional valve and the oil inlet of the main cylinder (i.e., the oil inlet connected to the main cylinder's large chamber) to collect the hydraulic pressure of the main lifting system.
[0050] The aforementioned edge computing and control nodes are connected to the hydraulic lifting execution cluster and sensor network via CAN bus, respectively. They are built using high-performance industrial PLCs and embedded systems. Their core functions include: first, receiving and initially processing real-time data collected by the sensor network (specifically, filtering and extracting the real-time data); second, executing low-level closed-loop control based on multi-point synchronous error compensation based on the initially processed real-time data, and running basic PID synchronous control algorithms to maintain basic system operation; and third, receiving and executing optimized control commands issued by the large-scale intelligent decision-making center.
[0051] The aforementioned large-scale intelligent decision-making center, deployed on a local high-performance server or private cloud, is the core of the system's intelligent decision-making. This large-scale intelligent decision-making center communicates with edge computing and control nodes to receive pre-processed real-time data uploaded by the edge computing and control nodes (including the height difference of each lifting point, the main system oil pressure, the current position of the piston rod of the lifting cylinder, etc.). It combines this data with the system's historical operating data stored in the local high-performance server or private cloud (specifically, the operating parameters, working conditions, and fault records related to the hydraulic synchronous lifting process collected and stored during the system's historical operating cycle). Through the pre-trained core decision-making large-scale model, it performs working condition identification, dynamic prediction, decision optimization, and control strategy and parameter optimization, and issues optimized control commands to the edge computing and control nodes. This core decision-making large-scale model is obtained through pre-training based on the physical mechanism of hydraulic synchronous lifting and massive operating data.
[0052] The aforementioned human-computer interaction interface is communicatively connected to the large-scale intelligent decision-making center and the edge computing and control node, respectively. It is used to visualize and display the system status, dynamic prediction results, control decisions, and explanatory information. At the same time, it receives intervention commands from operators (such as emergency stop commands, parameter fine-tuning commands, etc.) and feeds them back to the large-scale intelligent decision-making center and / or the edge computing and control node. (Specifically, if several pre-commands are only emergency stop commands, they are fed back to the edge computing and control node; if several pre-commands are parameter fine-tuning commands, they are fed back to the large-scale intelligent decision-making center; if several pre-commands include both emergency stop commands and parameter fine-tuning commands, the emergency stop command is fed back to the edge computing and control node, and the parameter fine-tuning command is fed back to the large-scale intelligent decision-making center.) This enables human-computer collaborative management and control.
[0053] like Figure 2As shown, the aforementioned large-scale intelligent decision-making center consists of four core modules: a multimodal data fusion module, a digital twin module, a core decision-making large model, and a strategy output and interpretation module. The multimodal data fusion module receives pre-processed real-time data uploaded from edge computing and control nodes. Its function is to sequentially align, clean, denoise, extract features, and construct state vectors from the pre-processed real-time data and historical system operation data stored on local high-performance servers or in private clouds. The output is a high-quality, standardized system state vector for use by downstream modules. The digital twin module receives the real-time system state vector from the data fusion module and the physical parameters of the hydraulic lifting system (such as component material properties and hydraulic system performance parameters). Based on the system state vector and the physical parameters of the hydraulic lifting system, it constructs a high-fidelity virtual model, achieving real-time synchronization, state mapping, and simulation between the physical system and the virtual model. This module's functions include high-fidelity modeling, real-time synchronization and state mapping, and simulation, outputting real-time system status display and prediction data for future dynamics (i.e., simulation data). The core decision-making model module takes as input the state vector output from the data fusion module and the simulation data output from the digital twin module. Its core functions include: 1. Operating condition identification: specifically identifying the current load distribution, structural stiffness changes, and external wind load conditions; 2. Multi-step dynamic prediction: accurately predicting the synchronous deviation of each suspension point and the evolution of structural stress in future periods, and simultaneously completing fault diagnosis, location, and equipment health status determination; 3. Control strategy and parameter optimization: covering parameter adaptive tuning, path dynamic optimization, and intelligent decision generation, specifically including generating advanced control strategies or dynamically optimizing PID controller parameters, and dynamically planning the optimal lifting speed and path. The output of this core decision-making model module is the original, high-level decision command. The input to the control strategy and interpretation module is the original decision command generated by the core decision model module. The functions of this module are command conversion, interpretability analysis, and permission and security verification. Specifically, the control strategy and interpretation module converts the original decision command output by the core decision model into executable control commands, generates explanatory information on the decision basis (including working condition identification basis, dynamic prediction logic, decision optimization reasons and fault diagnosis descriptions), and performs permission verification and security verification on the control commands. The output is the optimized control command to the edge control node and the decision interpretation information to the human-machine interface.
[0054] Preferably, the aforementioned core decision-making model is trained based on the Transformer architecture. Furthermore, the training data for this core decision-making model integrates simulation data from hydraulic system dynamics models generated using software such as AMESim, historical lifting project operation data (i.e., sensor data, control commands, and equipment parameters from historical lifting projects), fault case data (i.e., fault records), and expert operating rules. Its training objective is to minimize the synchronization error of each lifting point and maximize lifting efficiency and system safety margin. By integrating physical mechanisms, it ensures that the model's decisions conform to the engineering laws of hydraulic lifting, and by training with massive amounts of operational data, it enhances the model's adaptability to complex working conditions.
[0055] The edge computing and control node of this invention and the large model intelligent decision-making center constitute a collaborative architecture of edge execution and central decision-making (the central decision-making includes cloud decision-making and local decision-making); the edge computing and control node is responsible for high real-time closed-loop control to ensure rapid response of the improved actions; the large model intelligent decision-making center is responsible for non-real-time decision-making and predictive optimization decision-making, avoiding complex calculations from occupying edge node resources and ensuring the real-time performance and stability of system control.
[0056] Example 2:
[0057] like Figure 3 As shown, this embodiment provides a large-model-driven hydraulic synchronous lifting control method. This method is applied to the aforementioned large-model-driven hydraulic synchronous lifting control system. Specifically, the method includes the following steps:
[0058] S1: The sensor network continuously collects real-time data of the hoisting system, including the current position of the piston rod of the hoisting cylinder, the status of the anchor, the hydraulic pressure of the main hoisting system, and the synchronous height difference signal of each hoisting point;
[0059] S2: The edge computing and control node receives and preliminarily processes the real-time data collected by the sensor network. Based on the preliminarily processed real-time data, it executes the underlying closed-loop control (i.e., the basic synchronization control algorithm) with multi-suspension point synchronization error compensation as the core to maintain the basic operation of the system. At the same time, it uploads the preliminarily processed real-time data to the large model intelligent decision-making center.
[0060] S3: After receiving the pre-processed real-time data, the large-scale intelligent decision-making center combines it with historical system operation data. Through the core decision-making large-scale model, it performs condition identification, dynamic prediction, and control strategy and parameter optimization to generate executable control commands and corresponding decision interpretation information. Subsequently, the control commands are sent to the edge computing and control nodes, and the decision interpretation information is pushed to the human-machine interface. Specifically, the dynamic prediction includes prediction of the synchronization deviation of each lifting point, stress distribution of key points of the lifted components, and the trend of hydraulic pressure change in the main lifting system within a preset time period, as well as fault diagnosis, location, and equipment health status determination. The control strategy and parameter optimization includes generating advanced control strategies and dynamically optimizing PID controller parameters, such as a globally optimal control strategy.
[0061] In step S3, when it is predicted that the synchronization deviation will exceed the threshold or a potential fault risk is identified, the large model intelligent decision center will generate early warning information and correction schemes, and provide them to the operator through the human-computer interaction interface.
[0062] S4: Edge computing and control nodes adjust their control behavior based on received control commands.
[0063] S5: Repeat steps S1 to S4 until the lifting and lowering task of the lifted component is completed.
