Description

Technical Field

[0001] This application relates to the field of automatic control technology, and in particular to an intelligent adaptive method and system for suspending and installing curtain walls on existing buildings. Background Technology

[0002] In urban renewal and renovation projects of existing large public buildings, it is often necessary to renovate the exterior facade and curtain wall while preserving the operation of internal businesses and without damaging the original main structure.

[0003] In traditional curtain wall renovation and installation, conventional construction methods typically employ a fixed, suspended installation approach. This involves directly connecting the curtain wall components to the main building structure using pre-set connectors, thereby establishing a static and immutable mechanical transmission path from the curtain wall to the main structure. This ensures the fixation and load-bearing capacity of the curtain wall, guaranteeing its basic installation stability.

[0004] However, existing buildings may have inherent problems such as structural aging and foundation settlement. At the same time, dynamic factors such as wind pressure fluctuations and temperature deformation can also cause stress changes. Traditional fixed installation methods cannot make adaptive adjustments based on these inherent problems and dynamic stress changes, which may ultimately impair the collaborative performance between the curtain wall system and the existing building, affecting the safety and long-term adaptability of the curtain wall installation. Summary of the Invention

[0005] This application provides an intelligent adaptive method and system for installing curtain wall suspension on existing buildings, which is used for adaptive adjustment of curtain wall suspension installation to ensure the stability of the curtain wall system and the existing building structure under stress.

[0006] Firstly, this application provides an intelligent adaptive method for installing curtain wall suspension on existing buildings, applied to a curtain wall suspension installation system. The method includes: determining reference stress data using multiple distributed force sensors located at multiple preset anchoring points in the main structure of the existing building under no curtain wall load; this reference stress data being associated with the curtain wall unit to be installed; acquiring the weight data of the curtain wall unit to be installed; and combining local wind data obtained from an external meteorological service system with the reference stress data, generating multi-point collaborative prestressing loading parameters adapted to the intelligent adjustment module in the suspension assembly using a pre-set structural simulation algorithm. The multi-point collaborative prestressing loading parameters are used to evenly distribute the force on each anchoring point based on the reference stress data, and to balance the additional stress generated by the self-weight of the curtain wall unit to be installed and the wind load of the foundation. During the suspension and fixing of the curtain wall unit to be installed, the real-time installation load is obtained through distributed force sensors. For the anchoring point at the same location, the sub-prestressing loading parameters corresponding to the real-time installation load are determined from the multi-point collaborative prestressing loading parameters. The real-time installation load is compared with the sub-prestressing loading parameters to calculate the load compensation value. Based on the load compensation value, a fine-tuning command is sent to the corresponding intelligent adjustment module to adjust the prestress.

[0007] By adopting the above technical solution, the initial stress benchmark of each anchorage point is first determined based on the reference stress data under no-load conditions. Then, combined with the curtain wall's self-weight and local wind force data, multi-point collaborative prestressing loading parameters are generated through structural simulation algorithms to achieve balanced force distribution at each anchorage point. During installation, distributed force sensors collect load data in real time, compare it with the corresponding sub-prestressing parameters to obtain compensation values, and drive the intelligent adjustment module to fine-tune the prestress, forming a closed-loop control of "benchmark calibration - parameter preset - real-time monitoring - dynamic compensation". This effectively mitigates stress fluctuations caused by aging of existing building structures, foundation settlement, and wind pressure and temperature deformation, avoids the rigid constraint defects of fixed installation methods, ensures collaborative stress distribution between the curtain wall and the building structure, and improves installation safety and long-term adaptability.

[0008] In some embodiments, in conjunction with the first aspect, the intelligent adjustment module is positioned between the preset anchoring point of the existing building structure and the hanging assembly of the curtain wall unit to be installed, serving as a load-bearing component connecting the two. The intelligent adjustment module includes a microprocessor, a drive unit, and a mechanical transmission actuator that are communicatively connected to the curtain wall suspension installation system. The intelligent adjustment module is used to receive the fine-tuning command and, through the microprocessor, control the drive unit to drive the mechanical transmission actuator to generate a telescopic displacement along the force axis. By changing the connection length between the anchoring point and the curtain wall unit, the connection tension is physically adjusted, thereby achieving dynamic loading and compensation of prestress.

[0009] By adopting the above technical solutions, this structural design enables the prestress adjustment to be operable and precise. It allows for dynamic tension adjustment without disassembling the curtain wall components, solving the problem that traditional fixed connectors cannot adapt to stress changes. At the same time, as a load-bearing component, it can ensure connection strength, balance adjustment flexibility and structural stability, ensure timely and accurate prestress compensation, and further enhance the self-adaptive capability of the curtain wall suspension system.

[0010] In conjunction with some embodiments of the first aspect, in some embodiments, before the step of generating multi-point collaborative prestressing loading parameters for the intelligent adjustment module in the suspension assembly by combining the weight data of the curtain wall unit to be installed with the local wind force data obtained from the external meteorological service system and the reference stress data through a preset structural simulation algorithm, the method further includes: controlling the intelligent adjustment module to perform a pre-inspection test force along the vertical load-bearing direction; recording the driving stroke of the intelligent adjustment module during the application of the pre-inspection test force, and using the driving stroke as the measured displacement of the anchor point under the action of the pre-inspection test force; calculating the ratio of the pre-inspection test force to the measured displacement to obtain the measured stiffness value of each anchor point area; comparing the measured stiffness value with the theoretical stiffness value in the preset structural simulation algorithm to calculate the stiffness correction amount; and using the stiffness correction amount to correct the preset structural simulation algorithm.

[0011] By adopting the above technical solution, the intelligent adjustment module is first controlled to apply a pre-test force, and the driving stroke is recorded to obtain the measured displacement. The measured stiffness value of each anchorage point is then calculated and compared with the theoretical stiffness value to obtain the correction amount, thereby correcting the structural simulation algorithm. The measured stiffness value can truly reflect the actual bearing characteristics of the existing building's anchorage points, avoiding inaccurate prestress parameters caused by the deviation between theoretical and actual values. This makes the subsequently generated multi-point collaborative prestressing loading parameters more consistent with the actual project, reducing the problems of uneven force and stress concentration caused by stiffness estimation deviations. This lays the foundation for subsequent precise prestressing adjustment and improves the reliability and adaptability of the entire installation method.

[0012] In some embodiments of the first aspect, after obtaining the weight data of the curtain wall unit to be installed, and combining it with local wind data obtained from an external meteorological service system and the reference stress data, a multi-point collaborative prestressing loading parameter adapted to the intelligent adjustment module in the suspension assembly is generated using a pre-set structural simulation algorithm. Specifically, this includes: according to the arrangement of each anchor point in the suspension area of ​​the curtain wall unit to be installed, decomposing the weight data into the self-weight distribution load of each anchor point according to the anchor point load-bearing ratio, the anchor point load-bearing ratio being pre-calibrated based on the relative position of the anchor point and the center of gravity of the curtain wall unit, and the bearing characteristics of the existing building's main structure; and combining the windward area of ​​the exterior facade of the curtain wall unit to be installed, calculating the load under the action of the local wind data using a structural simulation algorithm. The total wind load value of the curtain wall unit to be installed is calculated and broken down into wind load distribution values ​​for each anchor point according to the location and windward sequence of each anchor point. The reference stress data is converted into the additional load threshold that each anchor point can bear, which serves as the upper limit for the superposition of the self-weight distribution load and wind load distribution value of the curtain wall unit to be installed. The self-weight distribution load and wind load distribution value of each anchor point are superimposed to obtain the initial comprehensive additional load of each anchor point. If the initial comprehensive additional load does not exceed the corresponding additional load threshold, the initial prestress loading value of the intelligent adjustment module of the suspension component of each anchor point is calculated by combining the prestress compensation coefficient preset in the structural simulation algorithm. The initial prestress loading values ​​of all anchor points are integrated to obtain the initial multi-point collaborative prestress loading parameters.

[0013] By adopting the above technical solution, the self-weight of the curtain wall is decomposed according to the anchor point layout and load-bearing ratio, and the wind load is decomposed in combination with the windward area. The self-weight and wind load distribution values ​​of each anchor point are clarified, and the benchmark stress is converted into an additional load threshold to limit the upper limit of the stress. By superimposing and calculating the initial comprehensive additional load, and combining it with the prestress compensation coefficient, the initial prestress of each anchor point is determined, and the loading parameters are integrated to achieve precise load distribution and scientific prestressing. This process can avoid overloading of individual anchor points, ensure that the stress of each anchor point is balanced, conform to the bearing characteristics of the existing building structure, and effectively avoid problems such as curtain wall loosening and structural damage caused by uneven load distribution in traditional installation.

[0014] In conjunction with some embodiments of the first aspect, in some embodiments, after the step of superimposing the self-weight distribution load and the wind load distribution value of each anchorage point to obtain the initial comprehensive additional load of each anchorage point, the method further includes: if the initial comprehensive additional load exceeds the additional load threshold, then determining the excess load; calculating the remaining bearing capacity of each anchorage point; determining the anchorage points with remaining bearing capacity as target distribution points; and distributing the excess load to the target distribution points proportionally according to the proportion of the remaining bearing capacity of each target distribution point, so that the final comprehensive additional load of each anchorage point does not exceed the corresponding additional load threshold.

[0015] By adopting the above technical solution, when the initial comprehensive additional load exceeds the standard, the excess load and the remaining bearing capacity of each anchor point are first determined, target distribution points are selected, and the excess load is distributed proportionally according to the percentage of the remaining capacity. This design can make full use of the remaining bearing capacity of the anchor points to achieve reasonable load transfer, avoid damage to the main building structure or curtain wall system due to overloading of a single anchor point, and ensure that the final stress of all anchor points does not exceed the threshold. It takes into account both the rationality of load distribution and structural safety, solves the load matching problem under the condition of uneven bearing capacity of existing building anchor points, and improves the applicability and safety of the installation method.

[0016] In conjunction with some embodiments of the first aspect, after integrating the initial prestress loading values ​​of all anchor points to obtain the initial multi-point collaborative prestress loading parameters in some embodiments, the method further includes: establishing a force correlation table between each anchor point in a preset structural simulation algorithm. This force correlation table is obtained by simulating the application of virtual loads on the updated structural calculation model and recording the force transfer relationship between each anchor point; obtaining the real-time installation load and relative position of all anchor points in the current installation step, and calculating the net load requirement of each anchor point after eliminating the force interference of adjacent anchor points based on the force correlation table; and dynamically correcting the initial multi-point collaborative prestress loading parameters based on the net load requirement to obtain multi-point collaborative prestress loading parameters that adapt to the actual stress state of all current anchor points.

[0017] By adopting the above technical solution, a stress correlation table for anchorage points is established in the structural simulation algorithm to clarify the stress transfer relationship between each anchorage point. Then, combined with the current real-time installation load and relative position, the net load requirement after eliminating interference is calculated, and the initial prestressing loading parameters are corrected. This process eliminates parameter deviations caused by stress interference between adjacent anchorage points, making the prestressing loading parameters more closely match the actual stress state of each anchorage point. This achieves precise multi-point coordinated adjustment, avoids local stress concentration caused by stress interference, further optimizes the coordinated stress performance of the curtain wall and the building structure, and improves the stability and long-term effectiveness of the installation system.

[0018] In conjunction with some embodiments of the first aspect, in some embodiments, after the step of proportionally distributing the excess load to the target distribution point, the method further includes: based on the measured stiffness values ​​of each anchor point, calculating in reverse the target differential stroke required to physically transfer the excess load, wherein the target differential stroke includes the release stroke of the intelligent adjustment module corresponding to the overloaded anchor point and the preload stroke of the intelligent adjustment module corresponding to the target distribution point, wherein the overloaded anchor point refers to the anchor point where the initial comprehensive additional load exceeds the corresponding additional load threshold; generating a multi-axis linkage gradient adjustment command to drive the intelligent adjustment module involved in the load transfer. The blocks synchronize with each other at preset micro-step intervals, controlling the intelligent adjustment module of the overloaded anchor point to perform a release action, and the intelligent adjustment module of the target allocation point to perform a pre-tightening action; during the execution of the gradient adjustment command, the stress change rate of each anchor point is calculated in real time; if the sudden change value of the stress change rate of any anchor point exceeds the preset structural stability index, the step adjustment action of all intelligent adjustment modules is immediately paused and the current adjustment position is locked; the measured stiffness value of each anchor point is rechecked, and the adjustment stroke is corrected based on the checked measured stiffness value, and then the step adjustment action of load transfer is continued based on the corrected adjustment stroke.

[0019] By adopting the above technical solution, a stress correlation table for anchorage points is established in the structural simulation algorithm to clarify the stress transfer relationship between each anchorage point. Then, combined with the current real-time installation load and relative position, the net load requirement after eliminating interference is calculated, and the initial prestressing loading parameters are corrected. This process eliminates parameter deviations caused by stress interference between adjacent anchorage points, making the prestressing loading parameters more closely match the actual stress state of each anchorage point. This achieves precise multi-point coordinated adjustment, avoids local stress concentration caused by stress interference, further optimizes the coordinated stress performance of the curtain wall and the building structure, and improves the stability and long-term effectiveness of the installation system.

[0020] In conjunction with some embodiments of the first aspect, in some embodiments, the step of issuing fine-tuning instructions to the corresponding intelligent adjustment modules to adjust the prestress according to the load compensation value specifically includes: converting the load compensation value into the target adjustment stroke of each intelligent adjustment module, and dividing the target adjustment stroke into multiple equally divided working steps; controlling all relevant intelligent adjustment modules to perform synchronous pulse-type adjustment according to the working step, and collecting the current force value of each anchoring point in real time during the pause interval after each working step is completed; calculating the force difference value between two adjacent anchoring points, and determining whether the force difference value meets the preset coordination consistency index; if not, adjusting the driving speed of each intelligent adjustment module in the next working step in real time until the real-time force of all anchoring points does not exceed the preset allowable stress threshold, and the force difference value between adjacent points is within the preset force balance threshold.

[0021] By adopting the above technical solutions, the force imbalance caused by excessive adjustment at one time can be avoided. Synchronous pulse adjustment ensures coordinated action of each anchoring point, and force difference verification ensures balanced force at each point. Ultimately, the force at all anchoring points does not exceed the allowable threshold and is balanced, effectively improving the accuracy and coordination of prestress adjustment and further ensuring the stability and safety of the curtain wall suspension system.

[0022] In a second aspect, this application provides a curtain wall suspension installation system, which includes: one or more processors and a memory; the memory is coupled to the one or more processors, and the memory is used to store computer program code, the computer program code including computer instructions, and the one or more processors call the computer instructions to cause the curtain wall suspension installation system to perform the method as described in the first aspect and any possible implementation thereof.

[0023] Thirdly, this application provides a computer-readable storage medium including instructions that, when executed on a curtain wall suspended installation system, cause the curtain wall suspended installation system to perform the method described in the first aspect and any possible implementation thereof.

[0024] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0025] 1. By employing distributed force sensors to calibrate the reference stress, combining the curtain wall's self-weight and wind force data to generate multi-point collaborative prestressing loading parameters through structural simulation algorithms, and dynamically fine-tuning the prestressing through real-time load monitoring and intelligent adjustment modules, the core technical means effectively solve the technical problems of existing fixed suspension installation methods being unable to adapt to stress changes caused by aging of existing building structures, foundation settlement, and wind pressure and temperature deformation, resulting in poor coordination performance between the curtain wall and the building body, insufficient installation safety, and insufficient long-term adaptability. This achieves stable collaborative stress distribution between the curtain wall and the building body, significantly improving the technical effect of curtain wall installation safety and long-term adaptability.

[0026] 2. By employing technical methods such as disassembling the curtain wall's self-weight according to the anchorage location and load-bearing ratio, and disassembling the wind load in conjunction with the windward area, converting the benchmark stress into an additional load threshold, and determining the initial prestress of each anchorage point through superposition calculation and prestress compensation coefficient, the technical problems of uneven load distribution during curtain wall installation and easy overloading of individual anchorage points, leading to curtain wall loosening and damage to the main building structure, are effectively solved in the existing technology. This achieves precise load distribution and balanced force at each anchorage point, conforms to the load-bearing characteristics of the existing building structure, and avoids the technical effects of curtain wall loosening and structural damage.

[0027] 3. By employing a technique that establishes an anchorage point stress correlation table within the structural simulation algorithm, combines real-time installation load with relative position calculations to eliminate interference and determine the net load requirement, and dynamically corrects the initial prestressing loading parameters, the technical problem of prestressing parameter deviation and local stress concentration caused by interference between adjacent anchorage points, affecting the coordinated stress-bearing performance of the curtain wall and the building structure, is effectively solved. This achieves precise matching between prestressing loading parameters and the actual stress state of each anchorage point, eliminates stress concentration, optimizes coordinated stress-bearing performance, and enhances the stability and longevity of the curtain wall suspension system.

[0032] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0033] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0034] For ease of understanding, the following is an exemplary scenario description of the method provided in this implementation. Please refer to [link / reference]. Figure 1 This is a schematic diagram of a scenario for the intelligent adaptive existing building curtain wall suspension installation method in the embodiments of this application.

[0035] exist Figure 1In the existing building structure, distributed force sensors are arranged within the pre-set anchorage point area to collect reference stress data under no curtain wall load and to collect installation load in real time during the installation of curtain wall units. The pre-set anchorage points can be set at the corners, edges and middle of the key stress nodes of the curtain wall units to be installed, and are evenly arranged according to the geometric center of gravity and force transmission path of the curtain wall units to form a multi-point support system.

[0036] The curtain wall unit to be installed is connected to the preset anchor points through a suspension assembly. The suspension assembly integrates an intelligent adjustment module, which can receive fine-tuning instructions from the curtain wall suspension installation system and dynamically adjust the connection prestress. Each preset anchor point can integrate a distributed force sensor and an intelligent adjustment module. Alternatively, important anchor points that require active force adjustment can be selected to set the intelligent adjustment module, while other anchor points that only need to monitor stress changes are only equipped with distributed force sensors. This ensures the adjustment capability of key force nodes while taking into account engineering costs and implementation efficiency. In this application, in order to achieve force coordination and precise control of all anchor points and ensure the optimal dynamic adaptation performance between the curtain wall and the existing building structure, the former mode (i.e., each preset anchor point integrates a distributed force sensor and an intelligent adjustment module) is mainly adopted. In practical applications, the configuration strategy can be flexibly adjusted according to different situations.

[0037] As the control and data processing center, the curtain wall suspension installation system can acquire the weight data of the curtain wall units to be installed, obtain local wind data from the external meteorological service system, and combine the benchmark stress data collected by distributed force sensors with the real-time installation load. Through structural simulation algorithms, it generates multi-point collaborative prestressing loading parameters. After comparing and calculating the load compensation value, it sends fine-tuning instructions to the intelligent adjustment module to achieve force balance and dynamic adaptation during the curtain wall suspension installation process. This improves the safety and long-term adaptability of the curtain wall installation without damaging the existing building structure.

[0038] The following section provides a detailed explanation of the structure and working principle of the intelligent adjustment module provided in this application. Please refer to [link / reference needed]. Figure 2 This is a schematic diagram of the structure and connection relationship of the intelligent adjustment module in the embodiments of this application.

[0039] exist Figure 2 In this process, the intelligent adjustment module, as the core load-bearing and adjustment component, is set between the preset anchor points of the existing building's main structure and the hanging components of the curtain wall unit to be installed. Its two ends are rigidly connected to the preset anchor points and the hanging components, respectively, forming a complete force transmission path. At the same time, it undertakes the function of transmitting external forces such as the self-weight of the curtain wall unit and wind load to the existing building's main structure.

[0040] As the control core of the intelligent adjustment module, the microprocessor maintains real-time communication with the curtain wall suspension system via wired or wireless means. It can receive fine-tuning instructions issued by the system and has local data processing and instruction parsing capabilities. It can verify and decompose instructions, generate control signals that can be executed by the drive unit, and ensure the accuracy and real-time performance of instruction transmission.

[0041] As a power output unit, the drive unit can be in the form of electric servo, hydraulic or electromagnetic drive. Under the control of the microprocessor, it converts electrical energy or hydraulic energy into mechanical power to provide precise power output to the mechanical transmission actuator. Its output torque, speed and other parameters can be dynamically adjusted according to the adjustment requirements to adapt to the prestress adjustment range under different working conditions.

[0042] As a physical adjustment unit, the mechanical transmission actuator can adopt transmission forms such as lead screw and nut, gear and rack, or hydraulic push rod. Under the power drive of the drive unit, it generates bidirectional telescopic displacement along the force axis: when it is necessary to increase prestress, the actuator retracts towards the existing building structure, reducing the connection length between the preset anchor point and the hanging component, thereby increasing the connection tension; when it is necessary to reduce prestress, the actuator extends towards the curtain wall unit to be installed, increasing the connection length, thereby releasing the connection tension.

[0043] Through this structural design, the intelligent adjustment module can not only serve as a load-bearing component to ensure the connection strength between the curtain wall and the existing building structure, but also dynamically change the connection tension through precise expansion and contraction displacement adjustment, thereby realizing real-time loading and compensation of prestress. This effectively resolves stress changes caused by factors such as aging of the existing building structure, foundation settlement, wind pressure fluctuations, and temperature deformation, ensuring that the stress state of the curtain wall unit and the existing building structure always remains balanced and compatible, thus improving the safety and longevity of the curtain wall installation.

[0044] The following describes the process of the method provided in this implementation, using the above scenario as an example. Please refer to [link / reference]. Figure 3 This is a flowchart illustrating an intelligent adaptive existing building curtain wall suspension installation method in an embodiment of this application.

[0045] S101. Under the condition of no curtain wall load, the reference stress data is determined by multiple distributed force sensors set in multiple preset anchoring point areas of the existing building's main structure. The reference stress data is associated with the curtain wall unit to be installed.

[0046] The term "no curtain wall load state" refers to the initial state in which the curtain wall units to be installed are not suspended and no gravity, tension, or other loads are applied to the existing building structure or pre-set anchor points. In other words, the curtain wall units are not connected to the suspension components or anchor points. At this time, the existing building structure and anchor points are only subject to their own weight and there is no additional external load interference. The pre-set anchor point area refers to a specific area planned and marked in advance on the existing building structure for installing suspension components and connecting the curtain wall units to be installed. This area must meet the requirements of high structural rigidity, reliable load bearing, and no damage to the original structural force system. The curtain wall units to be installed refer to the curtain wall components that need to be suspended and installed. They are usually prefabricated curtain wall panels, and their size, weight, and material are determined according to the renovation requirements of the existing building's curtain wall.

[0047] This step is performed before the curtain wall unit is hoisted and suspended. It belongs to the preliminary preparation and benchmark calibration stage of the curtain wall suspension installation. The scenario is that the existing building main structure has completed the preset anchor point layout, the distributed force sensor has been installed and debugged, and the curtain wall unit to be installed is ready but no suspension operation has been carried out.

[0048] During execution, the curtain wall suspension installation system first confirms that there is no curtain wall load. This means the system detects that no curtain wall units are connected to the preset anchor points and no additional load is applied to them. Then, it sends data acquisition commands to all distributed force sensors deployed in the preset anchor point areas. Upon receiving the commands, the distributed force sensors collect stress data in real time at their respective anchor point areas for a preset duration to eliminate interference from instantaneous stress fluctuations. The average stress value within the collection duration is taken as the reference stress data for that anchor point. After data collection, the distributed force sensors synchronously transmit the reference stress data of each anchor point to the curtain wall suspension installation system. The system processes and stores the data, establishes a reference stress database, and associates the reference stress data of each anchor point with the corresponding curtain wall units to be installed in the area, ensuring accurate matching during subsequent retrieval.

[0049] The core purpose of this step is to establish an initial benchmark for the stress on the anchor points. This solves the problem that traditional installation methods do not consider the initial stress differences of existing building anchor points, which leads to deviations in subsequent prestress calculations and uneven stress distribution. It provides an accurate reference for the generation of subsequent prestress loading parameters and the comparison of real-time loads, avoiding safety hazards in curtain wall installation caused by the lack of an initial benchmark. At the same time, it can also detect abnormal initial stress in the anchor point area (such as excessive stress or uneven stress) in advance, which is convenient for early investigation of structural hazards.

[0050] S102. After obtaining the weight data of the curtain wall unit to be installed, the local wind force data obtained from the external meteorological service system and the reference stress data are combined to generate multi-point collaborative prestress loading parameters adapted to the intelligent adjustment module in the suspension component through a pre-set structural simulation algorithm. The multi-point collaborative prestress loading parameters are used to evenly distribute the force of each anchor point based on the reference stress data, and balance the self-weight of the curtain wall unit to be installed and the additional stress generated by the foundation wind load.

[0051] Among them, local wind data refers to real-time wind force and direction data of the building area where the curtain wall unit to be installed is located, including instantaneous wind speed, average wind speed, and maximum wind speed, which are used to calculate the additional stress generated by wind load on the curtain wall unit and anchor points; the pre-set structural simulation algorithm refers to a professional algorithm that is pre-stored in the curtain wall suspension installation system and is used to simulate the stress state of the curtain wall unit after installation and calculate the prestress loading parameters. It is based on the principles of structural mechanics and mechanics of materials and can be combined with parameters such as anchor point stiffness and load distribution for simulation calculation.

[0052] After obtaining the exact weight data of the curtain wall unit to be installed, the system retrieves the current local wind data from an external meteorological service system via a network interface. Subsequently, the system calls a pre-set structural simulation algorithm, inputting the baseline stress data obtained in step S101 as the environmental boundary conditions into the model. The algorithm simulates the process of mounting the curtain wall unit of that weight onto the existing building in a virtual environment, while superimposing the lateral load generated by the current wind data. The core objective of the simulation calculation is to find an optimal force balance scheme, ensuring that, after deducting the baseline stress, the additional stress generated by the added curtain wall self-weight and wind load is distributed as evenly as possible to each anchorage point, avoiding excessive stress at individual points. The final output of the calculation is a set of multi-point collaborative prestressing loading parameters, specifying the ideal initial tension that each intelligent adjustment module should achieve before the arch is joined.

[0053] More specifically, the curtain wall suspension installation system first acquires the weight data of the curtain wall unit to be installed. This data can be the design weight, factory weighing data, or real-time on-site weighing data, ensuring the accuracy and reliability of the weight source. Based on the placement of each anchor point within the suspension area of ​​the curtain wall unit, the system calls upon a pre-calibrated anchor point load-bearing ratio. This ratio comprehensively considers factors such as the relative position of the anchor point to the center of gravity of the curtain wall unit, the load-bearing characteristics of the existing building structure, and the distribution of structural stiffness, ensuring a more rational weight distribution. According to this load-bearing ratio, the system decomposes the overall weight of the curtain wall unit into loads corresponding to the self-weight of each anchor point, ensuring that each anchor point bears a vertical load matching its position, stiffness, and load-bearing capacity, avoiding insufficient stress on anchor points near the edges or excessive stress concentration on anchor points near the center of gravity.

[0054] Meanwhile, based on the windward area of ​​the facade of the curtain wall unit to be installed and combined with local wind data obtained from an external meteorological service system, the system calculates the total wind load acting on the entire curtain wall unit under the current wind conditions using a pre-set structural simulation algorithm. To make the wind load distribution more closely reflect the actual stress conditions, the system further decomposes the total wind load into wind load distribution values ​​corresponding to each anchor point based on the location and windward sequence of each anchor point. This ensures that anchor points in wind-sensitive areas such as the windward side and corners receive a more realistic load distribution, while anchor points on the leeward side or in sheltered areas are assigned relatively smaller wind loads, thus achieving a scientific distribution of wind load among multiple points.

[0055] After completing the distribution of self-weight and wind load, the system converts the reference stress data corresponding to each anchorage point to obtain the additional load threshold that each anchorage point can safely withstand. This threshold serves as the upper limit of the superposition of the self-weight distributed load and the wind load distributed value, ensuring that the total additional load of any anchorage point will not exceed the safe bearing capacity of the existing building structure, thus protecting the main structure of the existing building from damage from the source. Subsequently, the system superimposes the self-weight distributed load and the wind load distributed value of each anchorage point to obtain the initial comprehensive additional load of that anchorage point, and compares it with the corresponding additional load threshold. When the initial comprehensive additional load does not exceed the additional load threshold, it indicates that the current load distribution scheme is within the safe range. The system continues to combine the prestress compensation coefficient preset in the structural simulation algorithm to calculate the initial value of prestress loading that the intelligent adjustment module corresponding to each anchorage point needs to apply. This prestress compensation coefficient can effectively compensate for errors caused by installation gaps, structural deformation, temperature deformation, and force transmission lag, making the initial prestress value closer to the actual stress requirements.

[0056] Finally, the system integrates, matches and optimizes the initial prestress loading values ​​of all anchor points to form a complete, coordinated and balanced initial multi-point coordinated prestress loading parameter. This parameter provides a clear target basis for real-time adjustment during the subsequent curtain wall suspension and fixing process, ensuring that each intelligent adjustment module performs prestress adjustment according to the unified plan, and achieves force coordination and overall balance among multiple points.

[0057] In some embodiments, for anchor points where the initial comprehensive additional load exceeds the additional load threshold, the system determines that the anchor point is in an overloaded state and immediately initiates the overload handling process. The system first accurately calculates the excess load of the overloaded anchor point, that is, subtracting the additional load threshold from the initial comprehensive additional load to obtain a clear value of the excess load that needs to be transferred. This value serves as the basis for subsequent load redistribution. After determining the excess load, the system iterates through all preset anchor points and calculates the remaining bearing capacity of each anchor point, that is, subtracting the initial comprehensive additional load of the anchor point from the additional load threshold to obtain the space at which each anchor point can safely bear the additional load.

[0058] Subsequently, the system filters based on the calculation results, uniformly marking and determining target allocation points with a remaining load-bearing margin greater than zero and possessing safe load-bearing capacity. Only target allocation points can participate in the redistribution process of excess loads; anchor points without remaining load-bearing margins are excluded from allocation to avoid further exacerbating stress imbalance. After determining the target allocation points, the system first calculates the sum of the remaining load-bearing margins of all target allocation points, and then calculates the proportion of the remaining load-bearing margin of each individual target allocation point in the total margin, i.e., the remaining load-bearing margin percentage. The system strictly follows this percentage to distribute the aforementioned excess loads proportionally, ensuring that the additional load borne by each target allocation point matches its own remaining load-bearing capacity. Target allocation points with larger load-bearing margins bear more excess loads, while target allocation points with smaller load-bearing margins bear less excess loads, ensuring that load distribution is scientific, reasonable, and safe.

[0059] After proportionally distributing the excess load, the system recalculates and updates the comprehensive additional load of all anchor points, obtaining the final comprehensive additional load for each anchor point. The final comprehensive additional load is then checked against the corresponding additional load threshold to ensure that the final stress on all anchor points does not exceed the safe bearing capacity. This complete load redistribution process effectively solves the technical problems encountered during the renovation of existing building curtain walls, such as uneven initial bearing capacity of anchor points, and overloading of local anchor points due to the combined weight of the curtain wall and wind loads, leading to damage to the existing building structure. It also avoids safety hazards such as curtain wall loosening, connection failure, or even structural damage caused by overloading of a single anchor point.

[0060] In some embodiments, the reference stress is determined, but before the formal loading parameters are generated using simulation algorithms. Because existing buildings (old buildings) have been in use for many years, the actual mechanical properties of their concrete components, embedded parts, or anchors often deviate significantly from the design drawings from decades ago (e.g., carbonation, microcracks). To ensure that the "intelligent adjustment" is not based on erroneous "theoretical values," the system will instruct the intelligent adjustment modules at each anchoring point to perform a test.

[0061] Specifically, the system first controls the intelligent adjustment module at each preset anchoring point to perform a pre-test force along the vertical load-bearing direction (i.e., the main force direction after the curtain wall unit is suspended), avoiding stiffness data deviations caused by testing in non-load-bearing directions. Throughout the entire process of the intelligent adjustment module applying the pre-test force, the system records the drive stroke of the intelligent adjustment module in real time and directly uses this drive stroke as the measured displacement of the anchoring point under the corresponding pre-test force, ensuring that the displacement data completely corresponds to the force direction and test force. For example, the system controls the intelligent adjustment module to apply a 2000N pre-test force in the vertical load-bearing direction. After the force stabilizes, the microprocessor obtains the precise extension distance (i.e., drive stroke) from the drive unit. If the displayed stroke is 4mm, the measured stiffness value of the anchoring point area is obtained as 500N / mm by calculating the ratio of the pre-test force to the measured displacement (2000N ÷ 4mm). Next, the system precisely compares this measured stiffness value with the theoretical stiffness value of the anchorage area pre-stored in the pre-set structural simulation algorithm (e.g., predicted to be 600 N / mm based on design drawings). The system calculates the corresponding stiffness correction amount (e.g., a difference of 100 N / mm, or a correction coefficient of 0.83) based on the difference or ratio between the two values. Finally, the system feeds back the calculated stiffness correction amounts for each anchorage area to the pre-set structural simulation algorithm. By dynamically updating core parameters such as the elastic modulus of each anchorage node in the algorithm model, the system corrects the structural simulation algorithm, ensuring that the basis of subsequent calculations is consistent with the actual structural state of the existing building.

[0062] This step effectively addresses the pain points of opaque and inaccurate structural parameters in existing buildings, ensuring that the subsequently generated "multi-point collaborative prestressing loading parameters" truly match the "residual forces" of the old building. It not only corrects the algorithm's prediction accuracy but also avoids safety hazards caused by excessive adjustment travel or overloading due to misjudgment of structural rigidity.

[0063] In some embodiments, during the generation of multi-point collaborative prestressing loading parameters and subsequent installation, the spatial proximity of each anchorage point and the mutual transfer of structural forces may cause interference between adjacent anchorage points in the real-time installation load of a single anchorage point, resulting in a deviation between the multi-point collaborative prestressing loading parameters and the actual stress requirements. In this case, the following steps can be performed:

[0064] The system performs virtual excitation tests in the background structural simulation engine to construct a stress correlation table. Since the skeleton material, horizontal and vertical keel connection methods, and overall geometry of each curtain wall unit are different, its stiffness distribution is unique. In the digital model, the system sequentially applies standard unit virtual displacement or virtual force (e.g., lifting upwards by 1 mm or applying a 1000 Newton tension) to each anchor point, while keeping the constraints of other anchor points unchanged. The simulation algorithm uses finite element analysis to accurately calculate the transmission path of stress flow within the curtain wall panel caused by this operation and records the passive stress changes at all other anchor points. By traversing all anchor points and performing this type of virtual test, the system can generate a high-dimensional influence coefficient matrix, i.e., a stress correlation table. This table clearly defines how much the stress at point B on the right and the stress at point C below will increase if point A in the upper left corner is lifted. This provides a mathematical benchmark for subsequent "decoupling."

[0065] Secondly, after the actual installation work begins, the system enters a high-frequency real-time calculation phase. High-precision tension sensors and laser displacement sensors deployed at the installation site transmit real-time load values ​​and spatial coordinates of all anchorage points in milliseconds. At this point, directly comparing the real-time load with the target value for adjustment would lead to a vicious cycle of "adjustment-oscillation." For example, if the system detects insufficient force at point A, simply instructing the motor at point A to pull upwards would cause a sudden increase in force at point B due to the overall rigidity of the curtain wall, leading the system to misjudge point B as overloaded and instruct it to lower, which in turn causes insufficient force at point A again. To avoid this blind adjustment, the system uses the aforementioned force correlation table for reverse calculation. The system treats the total measured load at each point as a superposition of "signal" and "noise," using matrix operations to remove interference forces (i.e., "noise") transmitted from adjacent points from the total reading, thereby calculating the net load requirement for that anchorage point. This means the system can identify how much of the insufficient force at point A is due to its own improper positioning, and how much is caused by the adjacent point B being pulled too tight.

[0066] Finally, based on this net load requirement, which can only be obtained through deep calculation, the system dynamically corrects the initial multi-point coordinated prestressing loading parameters generated in S401. Instead of simply having each point chase its own target value, the system generates a set of coordinated instructions. For example, the system might generate a composite instruction like this: to ensure point A reaches the predetermined stress, the optimal solution, calculated through calculation, is not merely to adjust point A, but to raise point A by 2 mm while simultaneously lowering the strongly correlated point B by 0.5 mm, and keeping point C stationary. This coordinated correction based on global coupling ensures that the internal force distribution of the curtain wall unit smoothly transitions during adjustment, eliminating the risk of glass panel distortion and breakage caused by forced adjustment at a single point during installation, and achieving rapid, vibration-free, and high-precision mechanical balance of complex curtain wall units in a multi-point suspended state.

[0067] In some embodiments, during the physical transfer of loads after the overload distribution is completed, deviations in the previously measured stiffness, inaccurate calculations of the adjustment stroke, or instability in the existing building structure may lead to sudden stress changes and loss of adjustment control during load transfer, thereby damaging existing building components or curtain wall assemblies. In such cases, the following steps can be performed:

[0068] The system first uses the measured stiffness values ​​of each anchorage point and a pre-set structural algorithm to reverse-calculate the target differential stroke required for the physical transfer of excess load. It clearly distinguishes between the release stroke of the intelligent adjustment module corresponding to the overloaded anchorage point and the pre-tightening stroke of the intelligent adjustment module corresponding to the target distribution point, ensuring that the stroke calculation closely matches the actual stiffness state of each anchorage point and avoiding incomplete load transfer or over-adjustment due to stroke deviation. Subsequently, the system generates multi-axis linkage gradient adjustment commands, driving all intelligent adjustment modules involved in load transfer to move synchronously. Adjustments are made strictly according to preset micro-steps, controlling the intelligent adjustment module at the overloaded anchorage point to perform a release action, slowly unloading the excess load, while simultaneously controlling the intelligent adjustment module at the target distribution point to perform a pre-tightening action, smoothly absorbing the transferred load, achieving synchronous load transfer and gradual force transition. During the execution of the gradient adjustment commands, the system uses distributed force sensors to collect stress data at each anchorage point in real time, calculating and monitoring the stress change rate at each anchorage point in real time. If the sudden change in the rate of stress change at any anchor point exceeds the preset structural stability index, the system will immediately trigger a safety protection mechanism, suspend the step adjustment actions of all intelligent adjustment modules, and lock the current adjustment position to prevent the sudden change in stress from causing damage to the existing building structure and curtain wall system.

[0069] Afterwards, the system re-verifies the measured stiffness values ​​of each anchorage point, corrects stiffness data deviations, adjusts the target differential stroke based on the verified measured stiffness values, corrects adjustment deviations, and then continues to execute load transfer actions step by step according to preset small increments based on the corrected adjustment stroke, until the safe transfer of all excessive loads is completed. This step effectively solves the technical problems of unstable adjustment and sudden stress changes during load transfer, ensuring a smooth load transfer process throughout.

[0070] S103. During the process of suspending and fixing the curtain wall unit to be installed, the real-time installation load is obtained through distributed force sensors.

[0071] The process of suspending and fixing the curtain wall unit to be installed refers to the entire process of lifting the curtain wall unit to be installed using hoisting equipment, moving it to the preset installation position, initially connecting and temporarily fixing the curtain wall unit to the preset anchor points through suspension components, until the final fixing is completed. This process includes multiple stages such as hoisting and positioning, initial connection, temporary fixing, and final locking. Real-time installation load refers to the load value borne by each preset anchor point in real time during the suspension and fixing of the curtain wall unit, including the self-weight load of the curtain wall unit, the instantaneous load generated during hoisting, and the additional load generated by wind load, etc., and its value will change dynamically as the installation process progresses. Distributed force sensors continuously collect real-time load data of each anchor point during this process and transmit it synchronously to the curtain wall suspension installation system to ensure that the system can monitor the stress state of each anchor point in real time.

[0072] This step is executed from the initial hoisting and suspension of the curtain wall unit to its final fixation. It represents the core implementation stage of the curtain wall suspension installation. The scenario involves the curtain wall unit being lifted by the hoisting equipment, ready to be connected to the preset anchor points, with the distributed force sensors and the curtain wall suspension installation system both functioning normally. During execution, from the moment the hoisting equipment lifts the curtain wall unit to the preset installation height and begins initial docking with the suspension components, the curtain wall suspension installation system sends real-time acquisition commands to all distributed force sensors. The distributed force sensors then activate continuous acquisition mode, collecting load data at their respective anchor points every preset time interval (usually 1-5 seconds), which is the real-time installation load. When the curtain wall unit is initially attached to the preset anchor points, the real-time installation load is primarily a portion of the curtain wall unit's self-weight. During temporary fixation, as the connection between the curtain wall unit and the suspension components gradually tightens, the real-time installation load gradually approaches the full self-weight of the curtain wall unit, with additional loads from wind loads added. During final fixation, the real-time installation load tends to stabilize but may still experience slight variations due to wind fluctuations and fixing operations. The distributed force sensors transmit each set of real-time installation load data to the curtain wall suspension installation system in real time. The system receives and stores the data in real time and displays the load change curves of each anchor point in real time, so that staff and the system can keep track of the stress state during the installation process.

[0073] S104. For anchor points at the same location, determine the sub-prestressing loading parameters corresponding to the real-time installation load from the multi-point coordinated prestressing loading parameters.

[0074] Among them, the anchor point at the same location refers to the same preset anchor point as the anchor point where the distributed force sensor that is currently collecting real-time installation load is located. That is, each anchor point corresponds to a set of real-time installation load data, and the prestress loading parameters corresponding to the anchor point need to be matched.

[0075] When the system receives real-time installation load data from a specific sensor (representing a specific anchorage point) in step S103, it immediately retrieves the complete list of multi-point coordinated prestressing loading parameters. Based on the sensor's location number, the system quickly locates and extracts the theoretical target value specific to that anchorage point, i.e., the sub-prestressing loading parameter, from the list using an index. This step establishes a one-to-one correspondence between "reality" and "theory," ensuring that subsequent comparative analyses are performed on data from two different dimensions of the same physical object.

[0076] S105. Compare the real-time installation load with the sub-prestress loading parameters and calculate the load compensation value.

[0077] This step is performed after the sub-prestress loading parameters of each anchor point are determined in S104, and is synchronized with the acquisition of real-time installation load in S103. It belongs to the real-time comparison and compensation calculation stage in the curtain wall suspension installation process. The scenario is that the curtain wall suspension installation system has obtained the real-time installation load and corresponding sub-prestress loading parameters of each anchor point, and has the conditions for comparison calculation.

[0078] During execution, the curtain wall suspension installation system extracts the real-time installation load value (denoted as Factual) and the corresponding sub-prestressing loading parameter value (denoted as Ftarget) for each anchorage point. Using a preset comparison calculation formula, the difference between the two is calculated, i.e., the load compensation value (denoted as Fcomplement), calculated as Fcomplement = Ftarget - Factual. After calculation, the system judges the load compensation value: if Fcomplement is positive, it means the real-time installation load of the current anchorage point is less than the target prestressing load, and the prestress needs to be increased through the intelligent adjustment module to compensate for the difference; if Fcomplement is negative, it means the real-time installation load of the current anchorage point is greater than the target prestressing load, and the prestress needs to be reduced through the intelligent adjustment module to release the difference; if Fcomplement is 0, it means the real-time installation load of the current anchorage point is the same as the target prestressing load, and no prestress adjustment is needed.

[0079] Meanwhile, the system will verify the rationality of the calculated load compensation value. If the absolute value of the compensation value exceeds the preset reasonable range (such as exceeding 10% of the sub-prestress loading parameter), it will be judged as abnormal data. The system will re-collect the real-time installation load of the anchor point, re-select the sub-prestress loading parameter and recalculate to ensure the accuracy of the load compensation value.

[0080] This step solves the problem of traditional installation methods being unable to determine the force deviation during installation or the prestress adjustment range. Through precise comparison and calculation, the force deviation of each anchor point and the required adjustment range are clarified, providing accurate numerical basis for subsequent prestress fine-tuning and avoiding force imbalance caused by insufficient or excessive adjustment.

[0081] S106. Based on the load compensation value, send fine-tuning instructions to the corresponding intelligent adjustment module to adjust the prestress.

[0082] This step is executed after the load compensation value of each anchor point is calculated in S105, and it runs through the entire process of suspending and fixing the curtain wall unit to be installed. It belongs to the real-time adjustment and precise control stage in the curtain wall suspension installation process. The scenario is that the curtain wall suspension installation system has obtained the load compensation value of each anchor point, and the intelligent adjustment module communicates normally with the system and can execute commands normally.

[0083] During execution, the curtain wall suspension installation system, for each anchor point, first converts and breaks down the adjustment stroke based on the sign and absolute value of its load compensation value: the load compensation value is converted into the target adjustment stroke corresponding to each intelligent adjustment module, clarifying the total extension / retraction distance that each intelligent adjustment module needs to complete. When the load compensation value is positive, the target adjustment stroke is a contraction stroke (used to increase prestress); when the load compensation value is negative, the target adjustment stroke is an extension stroke (used to reduce prestress). Simultaneously, to avoid sudden changes in structural stress due to excessively rapid adjustment and to ensure smooth adjustment, the system breaks down the target adjustment stroke into multiple equally spaced working steps. The length of each working step is preset to a small value, ensuring that each adjustment step is precise and controllable.

[0084] Subsequently, the system generates corresponding fine-tuning instructions, specifying the adjustment direction, target adjustment stroke, working step distance, and initial drive speed, and sends these instructions to the corresponding intelligent adjustment modules. The system synchronously controls all relevant intelligent adjustment modules, performing synchronized pulse-style adjustments according to the decomposed working step distance. This means each intelligent adjustment module completes the adjustment action of each working step distance step by step at the same time rhythm, ensuring that the prestress adjustment of each anchorage point is synchronized and avoiding stress imbalance caused by asynchronous adjustments. During the pause after each working step distance is completed, the system controls distributed force sensors to collect the current force value of each anchorage point in real time, ensuring timely capture of force changes after adjustment and providing data support for subsequent verification and adjustment.

[0085] After acquiring the current force value, the system immediately calculates the force difference between two adjacent anchor points. By comparing the force differences between adjacent anchor points, it determines whether the force difference meets a preset consistency index. This index is used to regulate the force deviation range of adjacent anchor points, ensuring that each anchor point experiences coordinated force and overall balance. If the force difference meets the consistency index and the real-time force of each anchor point does not exceed the preset allowable stress threshold, the system controls the intelligent adjustment module to continue executing the adjustment action of the next working step. If the force difference does not meet the preset consistency index, or the real-time force of any anchor point exceeds the allowable stress threshold, the system adjusts the drive rate of each intelligent adjustment module in the next working step in real time. For intelligent adjustment modules corresponding to anchor points with excessive force, the drive rate is reduced to slow down the adjustment amplitude; for intelligent adjustment modules corresponding to anchor points with insufficient force, the drive rate is appropriately increased to accelerate the adjustment amplitude, ensuring that the force difference between adjacent anchor points gradually decreases.

[0086] The above process is repeated until the real-time stress at all anchor points does not exceed the preset allowable stress threshold, and the stress difference between adjacent points is within the preset stress balance threshold. Only then does the system issue a stop adjustment command, and the intelligent adjustment module locks the current adjustment position, completing this round of prestress fine-tuning. This step solves the core technical problem that traditional fixed installation methods cannot adaptively adjust according to stress changes, leading to stress concentration and poor coordination between the curtain wall and the main structure. Through stroke splitting, synchronous adjustment, real-time verification, and dynamic speed regulation, precise and stable prestress adjustment is achieved, ensuring balanced and controllable stress at each anchor point.

[0087] To achieve balanced stress distribution on the curtain wall during installation, this application does not simply passively mount the curtain wall units onto the existing building. Instead, it employs a closed-loop control strategy of "active optimization and dynamic approximation." This step involves active displacement compensation. If an anchor point experiences "premature / excessive stress," this typically indicates a structural bulge or tilted hoisting posture at that location. The system immediately determines that this point may become a "stress concentration point" and controls the corresponding intelligent adjustment module to perform a slight elongation (release) action, actively "yielding" a portion of the load and forcing excessive force to transfer to other unstressed anchor points. If an anchor point experiences "delayed / insufficient stress," this indicates structural indentation or poor contact at that location. The system controls the corresponding intelligent adjustment module to perform a slight contraction (pre-tightening) action, actively "grabbing" the load and assuming its proper share. Through this high-frequency "monitoring-comparison-adjustment" cycle, the system forcibly corrects uneven stress distribution caused by architectural errors before the curtain wall weight is fully transferred to the building structure. Therefore, this method essentially uses the calculated "static parameters" as the "baseline for dynamic adjustment". Through the real-time expansion and contraction of the intelligent module during the installation process, it offsets the geometric errors of the existing building and achieves stress balance of the curtain wall throughout the entire process.

The method according to claim 5, characterized in that, After the step of proportionally distributing the excess load to the target distribution point, the following steps are also included: Based on the measured stiffness values ​​of each anchor point, the target differential stroke required to physically transfer the overload is calculated in reverse. The target differential stroke includes the release stroke of the intelligent adjustment module corresponding to the overload anchor point and the preload stroke of the intelligent adjustment module corresponding to the target distribution point. The overload anchor point refers to the anchor point where the initial comprehensive additional load exceeds the corresponding additional load threshold. Generate gradient adjustment commands for multi-axis linkage to drive the intelligent adjustment modules involved in load transfer to synchronize at preset micro-steps, control the intelligent adjustment modules at overload anchor points to perform release actions, and control the intelligent adjustment modules at target distribution points to perform pre-tightening actions; During the execution of the gradient adjustment command, the stress change rate of each anchoring point is calculated in real time. If the sudden change value of the stress change rate at any anchor point exceeds the preset structural stability index, the step adjustment action of all intelligent adjustment modules will be immediately paused and the current adjustment position will be locked. The measured stiffness values ​​of each anchorage point are rechecked, and the adjustment stroke is corrected based on the checked measured stiffness values. Then, the step adjustment action of load transfer is continued based on the corrected adjustment stroke.

8. The method according to claim 1, characterized in that, The steps for adjusting the prestress by issuing fine-tuning commands to the corresponding intelligent adjustment module based on the load compensation value specifically include: The load compensation value is converted into the target adjustment stroke of each intelligent adjustment module, and the target adjustment stroke is divided into multiple equally divided working steps; Control all relevant intelligent adjustment modules to perform synchronous pulse adjustment according to the working step distance, and collect the current force value of each anchoring point in real time during the pause interval after each working step distance is completed. Calculate the force difference between two adjacent anchor points and determine whether the force difference meets the preset coordination consistency index. If the conditions are not met, the drive rate of each intelligent adjustment module in the next working step will be adjusted in real time until the real-time force of all anchor points does not exceed the preset allowable stress threshold, and the force difference between adjacent points is within the preset force balance threshold.
