Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated building construction, and in particular to a method for intelligently lifting and precisely positioning prefabricated building components. Background Art

[0002] In the construction of prefabricated buildings, special-shaped curved glass components have irregular geometric shapes, and their surface wind pressure distribution shows nonlinear characteristics. In addition, during the hoisting process, the tension of the lifting ropes, the stress and deformation caused by the deadweight of the components, and the external wind load are prone to coupling. This coupling effect will dynamically evolve with changes in environmental conditions and construction status, and places extremely high demands on the accuracy and safety of the hoisting operation.

[0003] Most existing lifting methods rely on construction workers to preset lifting parameters based on past experience, and complete positioning and calibration through manual visual inspection or static measuring instruments. However, due to the lack of a dynamic monitoring mechanism for wind-force coupling, it is difficult to perceive and respond to dynamic wind load changes and component force and deformation in real time. In actual construction, it is very easy to cause safety accidents such as breakage of special-shaped curved glass components and instability of lifting equipment, which seriously affect the quality and progress of prefabricated building construction. Summary of the Invention

[0004] The present application provides a method for intelligent lifting and precise positioning construction of prefabricated building components to solve the above-mentioned technical problems.

[0006] This solution utilizes multi-parameter fusion analysis and dynamic adjustment technology to precisely control the installation positioning deviation of special-shaped curved glass, significantly improving hoisting accuracy and meeting the stringent high-precision requirements of complex building structures. At the same time, construction efficiency is significantly improved: pre-optimization of the hoisting plan based on the simulation model effectively avoids repeated on-site debugging and reduces time costs; the dynamic adjustment mechanism can eliminate deviations in real time, eliminating the need for multiple hoisting corrections and further shortening the construction period. In terms of safety, this technology predicts the stress state of special-shaped curved glass components through information set simulation, successfully avoiding potential stress concentration and structural damage risks during the hoisting process. In addition, real-time monitoring of environmental parameters ensures that operations can be suspended in time under adverse weather conditions, comprehensively improving construction safety.

Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.

[0020] The embodiments of the present application are described in further detail below with reference to the accompanying drawings.

[0021] Most existing lifting methods rely on construction workers to preset lifting parameters based on past experience, and complete positioning and calibration through manual visual inspection or static measuring instruments. However, due to the lack of a dynamic monitoring mechanism for wind-force coupling, it is difficult to perceive and respond to dynamic wind load changes and component force and deformation in real time. In actual construction, it is very easy to cause safety accidents such as breakage of special-shaped curved glass components and instability of lifting equipment, which seriously affect the quality and progress of prefabricated building construction.

[0022] Based on this, the present application provides a construction method for intelligent lifting and precise positioning of prefabricated building components. By using multi-parameter fusion analysis and dynamic adjustment technology, the installation positioning deviation of special-shaped curved glass is accurately controlled, which significantly improves the lifting accuracy and meets the stringent high-precision requirements of complex building structures. At the same time, construction efficiency is also greatly improved: the pre-optimization of the lifting scheme based on the simulation model effectively avoids repeated on-site debugging and reduces time costs; and the dynamic adjustment mechanism can eliminate deviations in real time, eliminating the need for multiple lifting and correction steps, further shortening the construction period. In terms of safety, this technology predicts the stress state of special-shaped curved glass components through information set simulation, successfully avoiding potential stress concentration and structural damage risks during the lifting process; coupled with real-time monitoring of environmental parameters, it ensures that operations can be suspended in time under adverse weather conditions, thereby comprehensively improving construction safety. The complete recording of data throughout the construction process not only facilitates quality traceability and construction acceptance, but also effectively promotes the development of prefabricated building construction towards intelligence and standardization.

[0023] Figure 1 This is a schematic diagram of an application scenario provided by this application. During the hoisting of special-shaped curved glass in prefabricated building construction, the method provided by this application is applied to precisely control the installation positioning deviation of the special-shaped curved glass, significantly improving the hoisting accuracy and meeting the stringent high-precision requirements of complex building structures.

[0024] Specifically, the method of the present application is applied to any server, which uses the glass manufacturer, the equipment factory technical manual, and the building design and construction drawings as data analysis sources and communicates with the intelligent detection instrument system; through the server, the geometric parameter set of the special-shaped curved glass components provided by the glass manufacturer, the lifting equipment parameter set provided by the equipment factory technical manual, the construction site real-time environment parameter set provided by the intelligent detection instrument, and the building reference positioning parameter set provided by the building design and construction drawings are obtained, and the multi-parameter fusion analysis and dynamic adjustment technology are used to accurately control the installation positioning deviation of the special-shaped curved glass, forming a set of lifting and precise positioning construction methods, providing accurate lifting control instructions for lifting PLC control, significantly improving the lifting accuracy, meeting the stringent high-precision requirements of complex building structures, optimizing the quality of building lifting construction, ensuring the high-precision splicing of special-shaped curved components such as glass curtain walls, avoiding defects such as uneven gaps and misalignment, and significantly improving the aesthetics and overall quality of the building. The specific implementation method can refer to the following embodiments.

[0025] Figure 2 This is a flow chart of a method for intelligent hoisting and precise positioning of prefabricated building components provided in one embodiment of the present application. The method of this embodiment can be applied to the server in the above scenario. Figure 2 As shown, the method includes: S201. Obtain a geometric parameter set of a special-shaped curved glass component, a lifting equipment parameter set, a construction site real-time environment parameter set, and a building reference positioning parameter set.

[0026] The geometric parameter set of irregular curved glass components can be a set of parameters used to characterize the geometric features of irregular curved glass components, including the glass surface curvature radius, the coordinates of several glass vertices, the glass thickness distribution, and the locations of several glass hoisting connection nodes. This can be provided by the glass manufacturer. The lifting equipment parameter set can be a set of parameters reflecting the performance and operating status of the lifting equipment, including the range of hook degrees of freedom and the accuracy of cable length adjustment. This can be provided by the equipment's factory technical manual. The real-time construction site environmental parameter set can be a set of environmental condition parameters at the current moment of the construction site, including real-time wind speed and real-time wind direction angle. This can be provided by intelligent detection instruments. The building benchmark positioning parameter set can be a set of benchmark positioning information of the building in the construction coordinate system, including the coordinates of the installation endpoint of the irregular curved glass, the position of the laser target, the real-time hoisting starting point coordinates, the edge feature points of the uninstalled irregular curved glass, the directional tolerance threshold, and the angular tolerance threshold. This can be provided by the architectural design and construction drawings.

[0027] Specifically, in the construction of prefabricated buildings, the hoisting of special-shaped curved glass components is a high-risk, high-precision core link. Due to the complex geometric shape of special-shaped curved glass components, the center of gravity offset and the curved surface characteristics make it difficult to accurately calculate the force distribution, which can easily cause damage or installation deviation during the hoisting process. By obtaining the geometric parameter set of special-shaped curved glass components, the parameter set of hoisting equipment, the real-time environment parameter set of the construction site, and the reference positioning parameter set of the building, the scattered data sources are integrated into a unified input, which not only improves the data reliability, but also lays an adaptive foundation for subsequent simulation and adjustment, so that the hoisting process is transformed from experience-driven to data-driven, significantly reducing the human error rate, and systematically obtaining multi-source parameter sets to build a data foundation for the hoisting process. The specific necessity is reflected in the following: First, the geometric parameter set of special-shaped curved glass components is the core input of the lifting simulation. Its geometric characteristics determine the deformation behavior under wind load. Obtaining this parameter set can analyze the stress concentration risk caused by the complexity of the shape; second, the lifting equipment parameter set is the prerequisite for dynamic adjustment. The equipment load capacity and position data affect the lifting path planning. The lack of real-time updates will cause overload accidents; third, the real-time environmental parameter set of the construction site can be used to analyze the adaptability of environmental interference. The real-time collection of parameters such as wind speed can be used to analyze and predict the impact of sudden wind vibration, and make up for the lag of existing methods; finally, the building benchmark positioning parameter set provides a global positioning reference framework to ensure that the positioning operation is based on the building axis, eliminate the cumulative error caused by inconsistent coordinate systems, and obtain multi-dimensional parameters in a comprehensive and real-time manner to achieve the accuracy and dynamic response capability of subsequent intelligent analysis.

[0028] S202. Based on the geometric parameter set of the special-shaped curved glass component, the parameter set of the hoisting equipment, and the real-time environmental parameter set of the construction site, a special-shaped curved glass hoisting simulation information set is integrated to obtain the affected state characteristics of the special-shaped curved glass during the hoisting process.

[0029] The special-shaped curved glass hoisting simulation information set may be a comprehensive information set formed by integrating the special-shaped curved glass component geometric parameter set, the hoisting equipment parameter set, and the construction site real-time environment parameter set.

[0030] Specifically, during hoisting construction, irregularly shaped curved glass components are complex in shape. The force distribution during hoisting is influenced by the real-time construction site environment and the building, making it difficult to predict empirically. This step integrates parameter sets to generate a simulation information set and extracts the affected state characteristics. This is essential for the following reasons: First, the irregularly shaped curved glass hoisting simulation information set solves the problem of isolated multi-source data by integrating geometric, equipment, and environmental parameters into a unified simulation model. For example, combining ambient wind speed data with component geometric curvature can simulate the impact of wind pressure distribution on the glass's aerial posture, avoiding the one-sidedness of single-parameter analysis in existing methods. Second, the affected state characteristics are key intermediate variables for precise positioning. By quantitatively predicting displacement or stress, they provide a basis for subsequent deviation compensation. The simulation process enables hoisting rehearsals and identifies potential risks. Without this step, construction would be exposed to uncontrollable risks. On the one hand, the lack of affected state characteristics can lead to delayed deviation detection and prevent early intervention; on the other hand, insufficient information integration can amplify environmental interference and increase rework rates. Through dynamic simulation, multi-dimensional parameters are converted into operational state characteristics, realizing visualization and predictability of special-shaped curved glass during the hoisting process, providing a scientific basis for subsequent data fusion and adjustment to cope with the nonlinear and real-time changes in the aerial posture of special-shaped curved glass components.

[0031] S203: Fusing the affected state characteristics with the building reference positioning parameter set to obtain absolute deviation information of the special-shaped curved glass relative to the building reference positioning.

[0032] The absolute deviation information may be position deviation information of the special-shaped curved glass component relative to the building reference positioning parameter set.

[0033] Specifically, in the installation of irregularly shaped curved glass, the precise positioning of the irregularly shaped curved glass components is the core of the quality of the hoisting construction. However, existing methods suffer from low efficiency in detecting deviations during hoisting construction due to inconsistencies in the coordinates of the irregularly shaped curved glass and the installation endpoint, or inaccurate predictions of the direction and angle of the state. Therefore, we perform data fusion in this step to generate absolute deviation information: First, the building baseline positioning parameter set provides the global coordinate system, while the affected state characteristics of the irregularly shaped curved glass components provide the relative state of the components. The fusion of the two resolves the problem of inconsistent reference systems. Second, the absolute deviation information is a direct input for the dynamic adjustment of deviation correction. It quantifies the magnitude and direction of the error between the irregularly shaped curved glass components and the installation endpoint coordinates, guiding the precise compensation of the irregularly shaped curved glass components and the installation endpoint coordinates.

[0034] S204. Dynamically adjust the operating parameters of the hoisting equipment based on the absolute deviation information, and output a construction plan report for intelligent hoisting and precise positioning.

[0035] The intelligent lifting and precise positioning construction plan report can be a report on the lifting equipment operating parameter adjustment strategy and the component installation positioning correction method.

[0036] Specifically, during the hoisting of irregular curved glass in prefabricated building construction, dynamic adjustment of hoisting deviations is the key to intelligent hoisting. However, existing methods are slow and unrecorded, and deviation responses rely on manual operator intervention, resulting in long response delays. In rapidly changing environments (such as wind vibration), small deviations in the direction and angle of the irregular curved glass can rapidly amplify, leading to installation failures or safety accidents during the hoisting construction process. The lack of standardized reporting during the deviation adjustment process makes it difficult to trace quality issues in the hoisting process, resulting in high repair costs. This step dynamically adjusts the angle and direction deviations of the irregular curved glass during the hoisting process and outputs a hoisting construction report. First, dynamic adjustment achieves closed-loop control based on absolute deviation information. This eliminates the lag associated with manual adjustment and is particularly suitable for sensitive applications involving irregular curved glass, where the curved surface characteristics require high-frequency fine-tuning to ensure proper fit. Second, the intelligent hoisting precise positioning construction plan report provides a digital record of the entire process, supporting construction audits and optimization.

[0037] This solution utilizes multi-parameter fusion analysis and dynamic adjustment technology to precisely control the installation positioning deviation of special-shaped curved glass, significantly improving hoisting accuracy and meeting the stringent high-precision requirements of complex building structures. At the same time, construction efficiency is significantly improved: pre-optimization of the hoisting plan based on the simulation model effectively avoids repeated on-site debugging and reduces time costs; the dynamic adjustment mechanism can eliminate deviations in real time, eliminating the need for multiple hoisting corrections and further shortening the construction period. In terms of safety, this technology predicts the stress state of special-shaped curved glass components through information set simulation, successfully avoiding potential stress concentration and structural damage risks during the hoisting process. In addition, real-time monitoring of environmental parameters ensures that operations can be suspended in time under adverse weather conditions, comprehensively improving construction safety. The complete recording of data from the entire construction process not only facilitates quality traceability and construction acceptance, but also effectively promotes the development of prefabricated building construction towards intelligent and standardized directions.

[0038] In some embodiments, the geometric parameter set of the special-shaped curved glass component includes the curvature radius of the glass surface, coordinates of several glass vertices, glass thickness distribution, and positions of several glass hanging connection nodes; The lifting equipment parameter set includes the hook's freedom range and the cable length adjustment accuracy; the construction site real-time environment parameter set includes real-time wind speed and real-time wind direction; the building benchmark positioning parameter set includes the coordinates of the installation end point of the special-shaped curved glass, the laser target position, the real-time lifting starting point coordinates, the edge feature points of the uninstalled special-shaped curved glass, the direction tolerance threshold, and the angle tolerance threshold.

[0039] The radius of curvature of a glass surface can be a key indicator for describing the degree of curvature of a special-shaped curved glass surface. The coordinates of several glass vertices can be the three-dimensional locations of key control points on the special-shaped curved glass surface. The glass thickness distribution can be the thickness variation pattern in different areas of the special-shaped curved glass surface. The locations of several glass hoisting connection nodes can be the coordinates of the installation anchor points of the special hoisting equipment fixture.

[0040] Specifically, in the installation and construction scenario of special-shaped curved glass components, the geometric parameter set of the special-shaped curved glass components defines the morphology and structural characteristics of the special-shaped curved glass components themselves. If the curvature radius of the surface of the special-shaped curved glass is ignored, the deformation of the glass under stress cannot be accurately calculated, making it difficult to ensure the safety and stability of the special-shaped curved glass. Missing the vertex coordinate data of the special-shaped curved glass will cause deviations in the installation positioning of the special-shaped curved glass, affecting the building's appearance and overall structure. Failure to consider the thickness distribution of the special-shaped curved glass may cause the special-shaped curved glass to be damaged due to insufficient local strength when subjected to compressive loads. Ignoring the location of the lifting connection node between the lifting equipment and the special-shaped curved glass will cause the special-shaped curved glass to be unevenly stressed during the lifting process, posing a risk of falling.

[0041] The hook's freedom of movement can be the range of angular motion of the hoisting arm, constraining the component's mid-air posture adjustment capabilities. The cable length adjustment accuracy can be the length control error of the hydraulic winch system, determining the precision of fine-tuning positioning.

[0042] Specifically, during the installation of curved glass in prefabricated building construction, the parameters of the lifting equipment are crucial for ensuring the smooth operation of the lifting operation. The hook's range of freedom determines whether the lifting equipment can accurately lift the curved glass to the installation location. If the range is insufficient, the curved glass may not reach the designated location, affecting the construction progress of the lifting project. The cable length adjustment accuracy of the lifting equipment is directly related to the accuracy of the curved glass installation.

[0043] The real-time wind speed can be the intensity of the instantaneous wind load. The real-time wind direction angle can be the angle between the direction of wind action and the plane of the special-shaped curved glass.

[0044] Specifically, the real-time environmental parameter set for the construction site reflects the dynamic changes in the construction environment. Real-time wind speed and direction have a direct impact on the hoisting of special-shaped curved glass. The environment may cause the glass to shake during the hoisting process, or even cause the hoisting equipment on the construction site to lose control. Changes in wind direction can also increase the difficulty and risk of hoisting operations.

[0045] The coordinates of the final installation point of the curved glass can be the theoretical installation position of the curved glass. The laser target position can be the coordinates of the auxiliary positioning spot projected on-site. The coordinates of the starting point of the real-time lifting can be the initial lifting position of the curved glass. The edge feature point of the unmounted curved glass can be the coordinates of the connecting boundary of adjacent glass. The directional tolerance threshold can be the maximum allowable error in the horizontal position of the curved glass. The angular tolerance threshold can be the inclination tolerance of the normal direction of the curved glass.

[0046] Specifically, during the hoisting of special-shaped curved glass in prefabricated building construction, the building benchmark positioning parameter set provides a positioning and calibration basis for the precise installation of special-shaped curved glass. The coordinates of the installation endpoint of the special-shaped curved glass clearly define the final installation position of the special-shaped curved glass. The laser target position and real-time hoisting starting point coordinates help the hoisting PLC control system determine the hoisting path and starting position of the special-shaped curved glass. The edge feature points of the uninstalled special-shaped curved glass can be used to calibrate the position and angle of the newly installed special-shaped curved glass to ensure installation accuracy. The directional and angular tolerance thresholds provide quantitative evaluation criteria for installation quality.

[0047] This solution collects multi-dimensional data on the geometric parameters of irregular curved glass components, lifting equipment parameters, real-time construction site environmental parameters, and building benchmark positioning parameters. This creates a comprehensive data system for risk assessment of irregular curved glass installation, eliminating the data blind spots of existing single-parameter assessment methods. This establishes a scientific data baseline for subsequent dynamic coupling analysis of parameters between glass components, the construction environment, and lifting equipment.

[0048] In some embodiments, based on the curvature radius of the glass surface and the glass thickness distribution, finite element analysis is used to analyze the force distribution state of the special-shaped curved glass and determine the force distribution heat map; based on the range of freedom of the hook and the adjustment accuracy of the cable length, the kinematic constraint equation of the lifting equipment is used to analyze the real-time fluctuation speed, real-time fluctuation distance, and real-time fluctuation angle of the lifting point cable, and combined with the force distribution heat map, the center of gravity offset of the special-shaped curved glass is obtained; based on the real-time wind speed and real-time wind direction angle, the pressure distribution coefficient of the glass surface under different wind conditions is analyzed, and the wind-glass interaction is simulated, and combined with the force distribution heat map, the real-time swing amplitude and frequency of the special-shaped curved glass under wind load are obtained; based on the swing amplitude and frequency, combined with the center of gravity offset, the multi-body dynamics coupled finite element analysis technology is used to integrate them into a special-shaped curved glass lifting simulation information set.

[0049] A stress distribution heat map can be a visualization of the stress state of the curved glass obtained through finite element analysis. The center of gravity offset can be the offset of the center of gravity of the curved glass relative to its theoretical position during the hoisting process. The real-time swing amplitude and frequency can be the swing characteristic parameters of the curved glass under wind load.

[0050] Specifically, there is a risk of uncontrolled force on the special-shaped curved glass during the hoisting process. Due to the non-uniform thickness distribution of the special-shaped curved glass, local stress concentration will occur on the special-shaped curved glass. The multi-source data of geometric parameters, equipment capabilities, and environmental data are fragmented. Geometric parameters, equipment capabilities, and environmental data belong to independent systems and lack multi-physics field coupling analysis capabilities, which in turn causes decision-making to lag behind real-time working condition changes. This step integrates multi-source data to construct a hoisting simulation information set to dynamically reflect the actual status of the hoisting components during the construction process. The specific implementation process of the safety control process for hoisting special-shaped curved glass is as follows: First, the surface curvature radius and thickness distribution data of the special-shaped curved glass are extracted based on the design drawings, and the component geometric model is constructed through 3D modeling software. The surface of the model is non-uniformly meshed, and the mesh density is adjusted according to the curvature distribution of the surface of the special-shaped curved glass. The mesh is denser where the curvature is large and sparser where the curvature is small. The mesh density is dynamically adjusted according to the change in curvature. Displacement constraints are set in combination with the position of the hoisting connection node. After determining the node locations based on the lifting plan and working conditions, software (ANSYS and ABAQUS) was used to model the glass structure and generate a high-quality mesh. Using the displacement method within the finite element software, the node displacements were used as unknown quantities. By establishing the element stiffness matrix and the overall equilibrium equation, the displacement distribution of the irregularly shaped curved glass under load was solved, and stress and strain results were derived from the displacements. Displacement constraints were applied to the connection nodes based on the actual lifting conditions, limiting displacement in specific directions to simulate a fixed state. The glass's deadweight and dynamic loads were accurately applied. After completing the modeling and condition setting, the program was run to calculate stress values ​​at each mesh node. Using the post-finite element analysis cloud plot function, a color gradient corresponding to the stress value range was set to generate a stress distribution heat map. Subsequently, a center of gravity offset analysis was conducted: The kinematic constraint equations for the equipment were established based on the hook's range of freedom and the cable length adjustment accuracy. The hook's motion trajectory was simulated using the vertex coordinates and curvature radius geometric parameters of the irregularly shaped curved glass. Furthermore, point cloud data of obstacles at the construction site acquired through laser scanning was integrated, and a spatial topology analysis algorithm was used to generate an obstacle-avoiding lifting path that conformed to the shape characteristics of the irregularly shaped curved glass. During the hoisting process, the fluctuation speed, distance, and angle of the lifting point cables are monitored in real time. The wavelet analysis algorithm is used to extract the fluctuation characteristics of the special-shaped curved glass and superimpose them with the glass force distribution heat map obtained based on finite element analysis. Combined with the elastic modulus, Poisson's ratio and other parameters of the glass material, the center of gravity offset of the special-shaped curved glass is calculated through a dynamic mechanical model to accurately identify the risk of instability in the hoisting posture. In order to address the impact of wind loads on the hoisting of special-shaped curved glass, CFD computational fluid dynamics is used to model the wind field at the construction site based on real-time wind speed and wind direction data. Taking into account the asymmetric shape and thickness distribution differences of the special-shaped curved glass, the surface dynamic wind pressure of the special-shaped curved glass is calculated by combining its vertex coordinates and thickness distribution data, and a refined wind pressure distribution heat map is generated.This heat map is deeply coupled with the cable's wave characteristics, and time-frequency analysis is used to quantify the amplitude and frequency of wind-induced glass component swings. Finally, multi-source data integration is performed: the glass force distribution heat map, center of gravity offset, and wind load swing characteristics are input into the multi-body dynamics coupling analysis module. Combined with parameters such as the glass's mass distribution and moment of inertia, the directional synergy between the lifting equipment force and the wind load is dynamically evaluated.

[0051] This solution, through the in-depth integration and analysis of multi-source data, improved the accuracy of hoisting and positioning of special-shaped curved glass. This technology possesses strong environmental adaptability, incorporating dynamic factors such as wind load and equipment status in real time, reducing construction interruptions caused by inclement weather. Structural analysis and center of gravity assessment can proactively identify potential weaknesses in components, effectively avoiding the risk of damage during the hoisting process and significantly reducing the incidence of safety accidents on the construction site.

[0052] In some embodiments, based on the curvature radius of the glass surface and the glass thickness distribution, three-dimensional modeling is performed on the special-shaped curved glass to construct a three-dimensional geometric model of the special-shaped curved glass; based on the three-dimensional geometric model, a non-uniform gridding process with differentiated unit grid area is performed on the surface of the special-shaped curved glass mapped by the three-dimensional geometric model to determine spatial non-uniform grid distribution data; based on the spatial non-uniform grid distribution data, combined with the positions of several glass hoisting connection nodes, the actual constraint state of the special-shaped curved glass during the hoisting process is analyzed; based on the spatial non-uniform grid distribution data and the positions of several glass hoisting connection nodes, the position of each glass hoisting connection node in the space is analyzed. The key force coordinates mapped by the spatial non-uniform grid distribution data are used to determine several key force characteristic points; based on several key force characteristic points, the force state of each key force characteristic point during the hoisting process is analyzed according to the spatial non-uniform grid distribution data, and the stress value is determined; based on the actual constraint state, through finite element analysis, with the spatial non-uniform grid distribution data as the row dimension, the position of the glass hoisting connection node as the column dimension, and the stress value of the key force characteristic point as the matrix element, the force distribution matrix of the special-shaped curved glass is constructed; based on the force distribution matrix, the stress value is extracted, the force distribution state of the special-shaped curved glass is analyzed, and the force distribution heat map is determined.

[0053] The three-dimensional geometric model can be a digital three-dimensional solid model constructed based on the geometric parameters of the special-shaped curved glass. The spatial non-uniform grid distribution data can be a spatial grid dataset that dynamically adjusts the grid density based on curvature changes and thickness distribution differences when meshing the surface of the three-dimensional geometric model. The actual constraint state can be a set of boundary conditions that restrict the overall deformation of the glass when the glass hoisting connection nodes are subject to cable tension and clamp constraints during the hoisting process. Key force characteristic points can be the coordinate points of areas of stress concentration or deformation sensitivity on the special-shaped curved glass during hoisting. The stress values ​​can be the internal stress values ​​generated by external loads at the key force characteristic points. The force distribution matrix can be a matrix with spatial grids as row dimensions, hoisting connection nodes as column dimensions, and stress values ​​as elements, used to quantify the stress distribution in various areas of the glass under different hoisting point constraints. The force distribution heat map can be a mapping diagram generated by visualizing the force distribution matrix.

[0054] Specifically, during hoisting construction, irregular curved glass exhibits significant characteristics, including irregular curvature variations and non-uniform thickness distribution. Existing uniform meshing methods face difficulties. Coarse meshes in areas with sudden changes in curvature distort stress calculations, making it difficult to accurately identify local crack risk points. However, overly dense meshing, which pursues global high precision, leads to massive redundant calculations. This step analyzes the stresses acting on irregular curved glass during hoisting by precisely analyzing the stresses. The specific implementation process is as follows: First, based on the design drawings of the irregular curved glass, the specific curvature radius of the glass surface and the coordinates of several key vertices are input. Given the large curvature variations and irregular morphology of irregular curved glass, the non-uniform rational B-spline (NURBS) surface reconstruction algorithm is used. This algorithm accurately fits complex surfaces using control points and weights, generating a 3D geometric model that closely conforms to the actual component contours. Once the 3D geometric model is obtained, a non-uniform meshing strategy is employed. Taking into account the curvature variation and thickness distribution of irregularly shaped curved glass, the mesh size is refined, with smaller cells set in areas with sharp curvature changes and high stress concentration, such as curves and corners, to accurately capture stress variations. In areas with gentle curvature and relatively uniform stress distribution, the mesh size is appropriately increased to reduce computational complexity. This adaptive meshing method generates spatially non-uniform mesh distribution data with spatial coordinate labels. Each mesh cell is accompanied by its precise three-dimensional coordinate information, laying the foundation for subsequent analysis. The locations of the glass hoisting connection nodes are projected onto the mesh model, and based on actual hoisting conditions, a certain range of cells around the nodes is defined as a constraint zone. Considering that constraints may exist in different directions at the connection nodes during the hoisting process, the constraint directions of each constraint zone are analyzed in detail, and the degree of freedom restrictions in each direction are clarified. This generates a dataset of the actual constraint states, including the constraint directions and degree of freedom restrictions. This approach accurately maps the actual hoisting constraints onto the mesh model, making the analysis more accurate in line with the actual hoisting scenario. Based on the grid model, according to the grid curvature gradient and thickness change rate, the grid nodes in the curvature mutation area and the thickness thinning area are screened as candidate points. At the same time, combined with the stress conduction path analysis of the hanging point constraint area, the law of stress transmission from the hanging point to other parts of the glass is studied, and the coordinate set of the key stress characteristic points is further determined. . The stress value of each grid node is calculated through the finite element solution algorithm, and the stress component of each node in different directions is obtained. With non-uniform grid units as rows and hanging connection nodes as columns, the stress values ​​of the corresponding nodes are filled into the matrix to construct a complete force distribution matrix. This matrix comprehensively records the stress relationship between various parts of the glass and the hanging connection nodes, providing data support for subsequent visual analysis. The stress values ​​in the force distribution matrix are normalized to make their numerical range uniform, which is convenient for visual mapping. According to the stress magnitude, an intuitive force distribution heat map is generated through specific color spectrum mapping.

[0055] This solution improves stress analysis accuracy in stress analysis and hoisting applications for special-shaped curved glass by employing a non-uniform grid to focus on high-risk areas. This reduces stress calculation errors at locations with sudden changes in curvature compared to existing methods. Optimizing computational resource allocation through mesh sparsification reduces the number of finite element model elements, significantly shortening single simulation times and ensuring analysis efficiency meets the requirements of real-time hoisting control. The improved positioning accuracy of key stress-bearing feature points enhances the reliability of the hoisting solution. This optimized hoisting point location solution can significantly reduce the maximum stress value of the glass and minimize the rate of hoisting breakage.

[0056] In some embodiments, based on the laser target position, point cloud data of obstacles on the construction site are obtained through laser scanning, the obstacle impact of the special-shaped curved glass in the construction environment is analyzed, and a heat map of the obstacle space distribution is generated; based on the real-time lifting starting point coordinates and the installation end point coordinates of the special-shaped curved glass, combined with the obstacle space distribution heat map, several pre-selected lifting trajectories with no direct impact of obstacles are generated; based on the hook's degree of freedom range, the spatial swing boundary of the hook is analyzed, combined with several pre-selected lifting trajectories, the spatial activity boundary of the lifting equipment operation is obtained; based on the spatial activity boundary, combined with the cable length adjustment accuracy, the cable is analyzed along several pre-selected lifting trajectories. The degree of adjustability of the lifting trajectory during the lifting process; based on the degree of adjustability, by analyzing the movement of the lifting equipment, simulating the operating state of the lifting equipment when lifting special-shaped curved glass along several pre-selected lifting trajectories, analyzing the real-time fluctuation speed, real-time fluctuation distance, and real-time fluctuation angle of the lifting point cable, and obtaining the real-time fluctuation characteristics; based on the real-time fluctuation characteristics, combined with the force distribution heat map, analyzing the force differences in different parts of the glass; obtaining the structural characteristics of the special-shaped curved glass in the real-time environment of the construction site; based on the force differences, combined with the structural characteristics, analyzing the force conditions of several glass lifting connection node positions, and obtaining the center of gravity offset of the special-shaped curved glass during the lifting process.

[0057] Point cloud data can be a collection of coordinates of construction site obstacles captured by a laser scanner. A heat map of the spatial distribution of obstacles can be a visualization generated by applying a density clustering algorithm to the point cloud data. If an intervention is involved, the selected hoisting trajectory can be a set of preliminary hoisting paths connecting the real-time hoisting start point and the installation destination of the special-shaped curved glass, avoiding areas with dense obstacles.

[0058] Specifically, the unique asymmetric geometry and thin-walled structure of special-shaped curved glass make it extremely fragile during hoisting. A slight mistake, a shift in center of gravity, or external interference can cause deformation and fracture. Existing hoisting methods rely primarily on manual experience to assess obstacle impacts and plan paths. This step first involves a high-precision, all-around scan of the construction site using a laser target to capture the spatial coordinates of obstacles. This process converts various obstacles, such as cranes, scaffolding, and piles of construction materials, into massive amounts of point cloud data. This data is then deeply processed using 3D modeling technology to generate a heat map of the spatial distribution of obstacles. In the heat map, red areas intuitively show areas with high density of obstacles, yellow areas represent medium interference ranges, and green areas indicate relatively safe areas. Based on the real-time lifting starting point coordinates and the installation end point coordinates of the special-shaped curved glass accurately marked in the construction design drawings, combined with the above-mentioned obstacle spatial distribution heat map, several pre-selected lifting trajectories without direct interference from obstacles were screened from potential paths. Considering the unique shape and center of gravity distribution of special-shaped curved glass, each pre-selected trajectory has undergone multiple rounds of optimization to ensure the stability of the glass during the lifting process. The range of freedom of the hook is an important factor affecting lifting safety. Combined with the cable length adjustment accuracy, each pre-selected lifting trajectory was deeply analyzed. Taking a certain trajectory as an example, when the hook moves to a specific position, it is found through calculation that the length of the cable that needs to be adjusted exceeds the allowable range of adjustment accuracy. At this time, the trajectory segment is immediately marked as a high-risk area and the trajectory is re-optimized and adjusted. In the process of simulating the operation of the lifting equipment along the pre-selected trajectory, high-precision sensors are used to monitor the fluctuation of the cables at the lifting points in real time, obtain the real-time fluctuation speed, distance and angle of the cables, and form detailed real-time fluctuation characteristic data. Combined with the force distribution heat map, the center of gravity offset of the glass during the lifting process is obtained, providing solid data support for the safe and smooth progress of the lifting operation.

[0059] Through this solution, during the construction and hoisting of special-shaped curved glass, precise environmental perception is achieved through laser scanning and thermal mapping technology, which transforms the complex construction environment into a visual risk map, greatly improving the accuracy of obstacle recognition, effectively eliminating blind spots in manual inspections, and avoiding collision accidents. Based on precise environmental perception, intelligent path planning is achieved, which integrates equipment motion constraints and environmental restrictions to generate pre-selected trajectories, ensuring that the hoisting path not only meets the physical limits of the equipment, but also avoids risk areas, significantly reducing the frequency of emergency braking. Data-driven decision-making provides real kinematic input for subsequent center of gravity offset calculations, achieving a coordinated improvement in safety and efficiency, and reducing the time-consuming repeated adjustments during the hoisting process.

[0060] In some embodiments, based on the real-time wind speed and real-time wind direction angle, the wind field in the real-time environment of the construction site is three-dimensionally modeled, and the special-shaped curved glass at different hoisting positions is analyzed to obtain the real-time wind load conditions of the special-shaped curved glass at each hoisting position, and the real-time wind load distribution of the special-shaped curved glass at different hoisting positions is determined; based on the real-time wind load distribution, combined with the glass vertex coordinates and glass thickness distribution, the dynamic wind loads acting on different areas of the special-shaped curved glass are analyzed to exert real-time differentiated pressures on the areas where they are located, and a pressure distribution heat map of the real-time wind load acting on the surface of the special-shaped curved glass is determined; based on the pressure distribution heat map, combined with the real-time fluctuation characteristics, the real-time swing amplitude and frequency characteristics of the special-shaped curved glass under wind load are obtained.

[0061] Wind-glass interaction refers to the complex physical coupling between the dynamically changing natural wind field and the physical entity of the irregularly shaped curved glass during installation. Real-time oscillation amplitude and frequency characteristics refer to the spatial oscillation range and number of periodic vibrations caused by the real-time wind load during installation. These characteristics are used to characterize the impact of wind loads on the dynamic behavior of the glass.

[0062] Specifically, irregularly shaped curved glass is extremely sensitive to wind loads. Due to its complex spatial geometry, it generates complex vortexes in the wind field, resulting in uneven surface pressure. In addition, its low bending and torsional stiffness can easily cause significant swaying even with relatively small wind loads. Existing lifting methods underestimate or ignore the impact of wind loads, resulting in poor positioning accuracy, high safety risks, and low efficiency. This step achieves refined, real-time prediction of the complex motion behaviors of irregularly shaped curved glass under dynamic wind loads, such as the swing amplitude and frequency, through real-time wind field monitoring in the lifting construction site, high-precision wind-glass interaction simulation, and coupled analysis with structural / constraint states. This lays the foundation for resolving the shortcomings of existing technologies and achieving intelligent, precise, and safe lifting. The implementation process includes: In the dynamic wind field modeling phase, work is first carried out based on real-time data from wind speed and direction sensors and a three-dimensional digital model of the construction site: the wind speed and direction sensors continuously monitor the meteorological environment around the construction site at an extremely high sampling frequency, transmitting key data such as wind speed, direction, and turbulence intensity in real time. Dynamic wind field modeling is performed using computational fluid dynamics (CFD) principles and empirical flow field models. Based on the Navier-Stokes equations, CFD technology divides the three-dimensional space of the construction site into tens of thousands or even millions of tiny grid cells through numerical calculations, meticulously solving the air flow velocity and direction within each grid cell. Next, the wind pressure calculation and conversion phase begins. The established wind field model is applied to the digital geometric model of the irregular curved glass to calculate the dynamic wind pressure on the glass surface at different times and locations. The calculated dynamic wind pressure is further converted into a pressure distribution coefficient, which is obtained by normalizing the wind pressure at each point with a reference wind pressure. The pressure distribution coefficient is then applied as a load to a finite element structural model containing information about the current state of the glass. At this point, the physical process of wind-glass interaction is simulated using fluid-structure coupling simulation technology or a simplified dynamic model. Fluid-structure coupling simulation technology accurately accounts for the interplay between air flow and structural deformation of the glass. When wind blows across the glass surface, the force exerted on the glass causes subtle deformations, which in turn influence the surrounding airflow distribution. Fluid-structure coupling simulation technology meticulously simulates this complex, two-way interaction, providing timely analysis results for lifting operations. After the simulation is complete, the motion trajectories of key glass points are analyzed in depth. These key points are typically located at locations such as the center of gravity of curved glass, vulnerable edges, and fixed points for connecting to lifting equipment. By extracting the real-time swing amplitude and frequency of these key points, the dynamic response of the glass under wind loads can be intuitively reflected. The calculated results, including dynamic wind pressure, pressure distribution coefficient, key point motion trajectories, swing amplitude, and frequency, are integrated into a core parameter set, which is then output to subsequent analysis steps and serves as a crucial component of the lifting simulation information set.

[0063] This solution integrates multi-source data and advanced technologies to precisely capture wind-induced sway characteristics. It accurately predicts sway amplitude and frequency, provides early warning of risks, and implements deviation compensation, significantly improving hoisting safety and positioning accuracy. It also optimizes work schedules based on sway patterns, improving hoisting efficiency and accelerating construction progress. It effectively reduces the risk of glass breakage and protects building components. It also quantifies the impact of wind loads, enhancing construction controllability and providing feedback for closed-loop control, continuously optimizing system performance, and comprehensively addressing hoisting challenges under dynamic wind loads.

[0064] In some embodiments, based on the swing amplitude and frequency, the influence characteristics of the wind load acting on the special-shaped curved glass during the hoisting operation are analyzed, and the swing position amplitude, swing direction, and swing speed of the special-shaped curved glass under the action of the wind load are determined; based on the center of gravity offset, the influence characteristics of the hoisting equipment acting on the special-shaped curved glass during the hoisting operation are analyzed, and the offset position amplitude, offset direction, and offset speed of the center of gravity of the glass during the operation of the hoisting equipment are determined; based on the offset direction and the swing direction, the directional consistency of the hoisting equipment and the wind load during the hoisting operation of the special-shaped curved glass is analyzed; if the directional consistency is tending to the same direction, according to the same direction coupling effect of the swing direction and the offset direction, the swing position amplitude and the offset position amplitude, the offset speed and the swing speed are dynamically superimposed and gain corrected to obtain the superimposed yaw coupling displacement and the same direction coupling force of the special-shaped curved glass; if the directional consistency is tending to the opposite direction, according to the opposite direction coupling effect of the swing direction and the offset direction, the swing position amplitude and the offset position amplitude, the offset speed and the swing speed are dynamically offset and reduced. The offsetting yaw coupling displacement and reverse coupling force of the irregular curved glass are obtained by correction. The dynamic response characteristic parameter set of the irregular curved glass is integrated based on the superposition of the yaw coupling displacement, the offsetting yaw coupling displacement, the co-directional coupling force, and the reverse coupling force. The dynamic response characteristic parameter set can be used to characterize and analyze the comprehensive motion trend under the coupling effect. Based on the dynamic response characteristic parameter set, the multi-body dynamics coupling finite element analysis technology is used to simulate the spatial posture change sequence of the irregular curved glass and the components of the lifting equipment during the lifting process. The three-dimensional coordinates, rotation angles, and posture vectors of each component of the irregular curved glass and the lifting equipment at different times are determined and integrated into a component spatial posture evolution dataset. Based on the component spatial posture evolution dataset, the motion trajectory of the irregular curved glass under the coupling effect of wind and lifting equipment under the corresponding spatial posture is analyzed and recorded to form a motion trajectory curve characteristic dataset. The component spatial posture evolution dataset and the motion trajectory curve characteristic dataset are integrated to determine the irregular curved glass lifting simulation information set.

[0065] Multi-body dynamics coupled finite element analysis technology can be a technology that combines multi-body system dynamics with finite element analysis. It is used to simulate the interaction and mechanical response between glass and various components of the lifting equipment during the lifting process, achieving accurate modeling of complex dynamic processes. The dynamic response characteristic parameter set can be a parameter set used to characterize the comprehensive motion trend of glass under the coupling of wind load and lifting equipment, including superimposed / offset yaw coupling displacement and same-direction / reverse coupling forces. The component spatial posture evolution dataset can be a dataset that records the three-dimensional coordinates, rotation angles, and posture vectors of various components of special-shaped curved glass and lifting equipment at different times, reflecting the sequence of spatial posture changes during the lifting process. The motion trajectory curve feature dataset can be a dataset of the motion trajectory curve characteristics of glass under the coupling of wind and lifting equipment, used to analyze the motion patterns of glass during the lifting process.

[0066] Specifically, during the installation of irregularly shaped curved glass in prefabricated buildings, the dynamic coupling effect of wind load and lifting equipment is crucial. When wind acts on irregularly shaped curved glass, it causes the glass to swing, and changes in equipment parameters such as the hook's degree of freedom and the cable's accuracy will be superimposed on the wind-induced swing. For example, in actual construction, when the wind direction is in the same direction as the equipment's operating direction, the glass's swing amplitude will be significantly amplified. Therefore, integrating multi-source data, building an accurate simulation model, and predicting the dynamic response of the glass during the installation process in real time, and using this to guide equipment parameter adjustments, can ensure the accuracy and safety of the installation process. To address the above issues, this step adopts the following processing flow: Based on the real-time wind load distribution, a pressure distribution heat map of the glass surface at different lifting positions is determined, and then the swing position, amplitude, direction, and speed of the glass under wind load are analyzed. Based on the obtained center of gravity offset, the impact of the operation of the lifting equipment on the center of gravity of the glass is analyzed. Through accurate analysis of these factors, the influence of the operation of the lifting equipment on the center of gravity of the glass can be fully understood. The swaying direction of the glass under wind load is compared with the center of gravity offset caused by the operation of the lifting equipment. By real-time monitoring the angle between the swing direction and the center of gravity offset during the lifting process, the directional state of the special-shaped curved glass can be determined: when the angle is less than 90°, it is determined to be trending in the same direction; when the angle is ≥90°, it is determined to be trending in opposite directions. This judgment process is key to understanding the mechanism of multi-factor coupling. By clarifying the directional relationship between the two, it can provide an important basis for subsequent dynamic response analysis. If the swing direction of the glass is trending in the same direction as the center of gravity offset, the position amplitude and speed of the swing and offset are dynamically superimposed and gain corrected. During this process, the algorithm module of the data processing center, based on the principle of force interaction, conducts in-depth fusion analysis of the collected multi-source data. By establishing a data analysis model, it simulates the mechanical scenario of glass swing and center of gravity offset acting in the same direction under different wind speeds and attitude angles. Combining historical data with actual on-site working conditions, after multiple iterative calculations, it finally determines the accurate gain correction coefficient. This coefficient can effectively enhance the calculation accuracy of the same-direction effect and ensure the accuracy of subsequent dynamic superposition and result calculations. The position amplitude and speed data of glass swing and center of gravity offset are dynamically superimposed. During the superposition process, the mutual reinforcement characteristics of the two in the same direction are fully considered. According to the determined gain correction coefficient, the data is weighted. When it is detected that the swing speed and center of gravity offset speed are in the same direction and both reach a certain threshold, the gain correction coefficient is used to increase their weight in the superposition calculation, thereby simulating the actual state of the glass under compound motion. The data after dynamic superposition processing is again input into the data analysis model for accurate calculation. Through model calculation, the superimposed yaw coupling displacement is obtained, that is, the actual distance the glass deviates from the initial position under compound motion. At the same time, combined with finite element analysis, the same-direction coupling force is calculated.On the contrary, if the two directions tend to be opposite, the real-time swing and offset data are analyzed and processed according to the curvature and mass distribution characteristics of the glass surface. By establishing the balance equation of the reverse force and combining it with the correction coefficient, the offsetting yaw coupling displacement is calculated, the final stable position deviation of the glass is determined, the magnitude and direction of the resultant force acting on the glass under the reverse action are understood, and dynamic offset and reduction corrections are performed to obtain the offsetting yaw coupling displacement and reverse coupling force. Finally, all the above calculation results are integrated to form a dynamic response characteristic parameter set for special-shaped curved glass. This parameter set comprehensively covers the motion and force information of the glass under the coupling of multiple factors, and can effectively characterize the comprehensive motion trend of the glass under the coupling. Using multi-body dynamics coupling finite element analysis technology, based on the dynamic response characteristic parameter set, the spatial posture changes of the glass and the components of the lifting equipment during the lifting process are simulated. During the simulation, the glass and lifting equipment are treated as an interconnected multi-body system, taking into account the mechanical connections and interactions between the components. By solving multi-body dynamics and finite element equations, the 3D coordinates, rotation angles, and posture vectors of each component at different times are recorded, generating a detailed dataset of the spatial posture evolution of the irregular curved glass components. The motion trajectories of the components in each posture in the spatial posture evolution dataset are analyzed in depth, and a least-squares curve fitting method is used to generate a motion trajectory curve feature dataset. This dataset clearly depicts the changing motion trajectory of the glass in different spatial postures, affected by the coupling effects of wind and lifting equipment. Finally, the component spatial posture evolution dataset and the motion trajectory curve feature dataset are integrated to form a complete information set for the simulation of irregular curved glass lifting.

[0067] This solution comprehensively considers the interaction between wind loads and lifting equipment, conducting multi-body dynamics coupling analysis. This significantly improves the accuracy of lifting simulations and provides reliable data support for precise positioning. Based on this high-precision simulation information, the posture changes of the glass during the lifting process can be predicted in advance, and the lifting trajectory can be optimized to avoid collisions with obstacles, thereby enhancing construction safety.

[0068] In some embodiments, based on the spatial posture evolution data set, the data set is compared with the coordinates of the installation endpoint of the special-shaped curved glass, and the spatial position difference and angle difference between the hoisting position of the special-shaped curved glass and the target position are analyzed to generate a preliminary deviation data set; based on the edge feature points of the uninstalled special-shaped curved glass, the edge spacing and relative angles between the special-shaped curved glass and the adjacent components are analyzed, and the preliminary deviation data set is corrected to obtain a relative position deviation set; based on the direction allowable deviation threshold and the angle allowable deviation threshold, the relative position deviation is judged as out of limit; if the deviation amounts are both within the direction allowable deviation threshold and the angle allowable deviation threshold, a normal deviation state is generated; if the deviation amount exceeds any one of the direction allowable deviation threshold and the angle allowable deviation threshold, combined with the swing direction and the offset direction, an absolute deviation information set including the deviation direction, deviation amount, and deviation angle is generated.

[0069] The spatial posture evolution dataset can be a sequence of three-dimensional spatial postures that record the time-varying changes in the irregular curved glass and various components of the lifting equipment during the entire lifting process. The directional tolerance threshold can be the maximum position offset allowed by the design specifications. The angular tolerance threshold can be the maximum angular offset allowed by the design specifications. The swing direction can be the direction of the glass swing vector caused by wind loads. The offset direction can be the direction of the center of gravity swing vector caused by the operation of the lifting equipment.

[0070] Specifically, dynamic posture calibration requires precise alignment of the spatial posture evolution dataset reflecting the real-time motion of the glass with the static installation coordinates and the actual positions of adjacent components. Positional deviations of installed components can be transmitted to subsequent component installations. By selecting feature points along the edges of the installed component to establish a local reference system, the impact of historical errors can be effectively isolated. To address this issue, this step employs the following process: By comparing the 3D coordinates and rotation angles at each moment in the component's spatial posture evolution dataset with the target endpoint coordinates of the special-shaped curved glass installation, the spatial offsets between the installation position and the target position along the X, Y, and Z axes, as well as the differences in pitch, yaw, and roll angles, can be accurately calculated. The real-time 3D coordinates of the glass during installation are then compared with the target coordinates one by one, and the positional offsets along the X, Y, and Z axes are calculated from the coordinate differences. These calculation results are integrated to generate a preliminary deviation dataset, providing the foundational data for subsequent deviation correction. Based on these preliminary deviation analysis results, the adjacent component deviation correction phase begins. The core of this phase is to establish a local spatial reference coordinate system using feature points along the edges of the installed component. The hoisting PLC control system will select at least three non-collinear feature points on the edge of the installed component, construct a local spatial reference coordinate system through these feature points, and then project the vertex coordinates of the glass to be installed into this coordinate system. The spatial distance and relative angle between each vertex and the edge of the adjacent component are analyzed, and the position and angle differences in the preliminary deviation data set are corrected according to the analysis results. Comparing the relative position deviation set with the preset direction and angle allowable deviation thresholds is the main task of the over-limit judgment and absolute deviation generation links. If all deviations are within the threshold range, it is judged to be a normal deviation state, indicating that the installation position and posture of the glass meet the requirements and subsequent construction can continue. If any deviation exceeds the limit, combined with the swing direction of the glass and the center of gravity offset direction during the hoisting process, an absolute deviation information set containing the specific deviation direction, deviation amount and deviation angle is generated.

[0071] This solution dynamically corrects deviations and integrates multi-source data, enabling real-time responses to dynamic environmental factors such as wind and equipment fluctuations, effectively avoiding cumulative deviations and precisely controlling the edge spacing and relative angles of adjacent components. This improves the waterproofing, airtightness, and appearance consistency of the building curtain wall. Its closed-loop feedback adjustment mechanism also significantly reduces the number of repeated corrections during the hoisting process, significantly improving construction efficiency, shortening the construction period, and reducing labor costs and equipment losses.

[0072] In some embodiments, based on the edge feature points of the uninstalled special-shaped curved glass, a local spatial reference coordinate system based on the actual structure of the building is established; the vertex coordinates of the special-shaped curved glass are projected to the local spatial reference coordinate system, and the spatial coordinates of each vertex of the special-shaped curved glass to the edge feature points of the adjacent components are analyzed to generate a vertex-edge distance mapping table; based on the vertex-edge distance mapping table, the edge spacing and relative angles between the special-shaped curved glass and the adjacent components are analyzed to obtain spatial position deviation and spatial angle deviation; based on the spatial position deviation and spatial angle deviation, the edge spacing and relative angles between the special-shaped curved glass and the adjacent components are analyzed, and the spatial position difference and spatial angle difference in the preliminary deviation data set are corrected to obtain an accurate relative position deviation set.

[0073] The local spatial reference coordinate system can be a three-dimensional spatial coordinate system established using non-collinear feature points based on the actual building structure, used to represent the relative spatial positional relationship between the irregular curved glass and adjacent installed components. The vertex coordinates can be the spatial coordinate values ​​of each vertex in the three-dimensional model of the irregular curved glass component. The vertex-edge distance mapping table can be a mapping table that records the spatial distances and relative positional relationships between each vertex of the irregular curved glass and the edge feature points of adjacent, uninstalled irregular curved glass. The spatial position deviation can be the coordinate difference between the actual hoisting position and the target position of the irregular curved glass in three-dimensional space. The spatial angle deviation can be the angular difference between the actual posture of the irregular curved glass and the designed posture in three-dimensional space, including deviations in pitch, yaw, and roll angles. The preliminary deviation dataset can be obtained by comparing the spatial posture evolution dataset of the irregular curved glass with the installation endpoint coordinates, including position and angle differences. The relative position deviation dataset can be accurate deviation data obtained by correcting the preliminary deviation dataset based on the edge feature points of the uninstalled irregular curved glass, used to guide the precise adjustment of the hoisting equipment.

[0074] Specifically, during the installation of special-shaped curved glass in prefabricated buildings, the special-shaped curved glass to be installed is adjusted based only on the theoretical design coordinates, while the actual positions of the adjacent installed components are ignored. The errors in each installation will continue to accumulate. To address the above problems, this step adopts the following processing flow: Establish a local reference coordinate system. The first step in correcting the relative position deviation is to build a reliable local reference coordinate system. A local spatial reference coordinate system is established from the edge feature points of the adjacent, uninstalled special-shaped curved glass, combined with the horizontal and vertical directions of the component edges. This coordinate system can closely fit the actual state of the installed components and provide an accurate benchmark for subsequent deviation corrections. After the local reference coordinate system is established, the coordinates of each vertex of the special-shaped curved glass need to be converted from the global coordinate system to the local coordinate system. This process is achieved through a coordinate transformation matrix, involving geometric transformation operations such as translation and rotation. Because the vertex coordinates of irregular curved glass are determined in the global coordinate system based on the overall building design benchmark, while the local reference coordinate system reflects the actual positions of adjacent installed components, coordinate transformation allows for a direct correlation between the glass vertex position information and adjacent components, facilitating subsequent analysis of their relative positional relationships. In the local coordinate system, the spatial distance from each vertex to the edge feature point of the adjacent component is calculated, typically using the Euclidean distance formula. The relationship between each vertex and the corresponding edge feature point is also recorded, forming a detailed vertex-edge distance mapping table. Based on the vertex-edge distance mapping table, the actual spacing and angle parameters recorded are compared with the design drawing requirements. By calculating the difference between the two, the actual edge spacing deviation and relative angular deviation between the current glass and the adjacent component are analyzed. This deviation data intuitively reflects the discrepancy between the glass installation position and the design requirements. The edge deviation and angular deviation are then fused and corrected with the spatial position and angular differences in the preliminary deviation dataset. The preliminary deviation data is then adjusted. This fusion and correction eliminates errors caused by external factors and generates an accurate relative position deviation set.

[0075] This solution significantly improves the installation accuracy of special-shaped curved glass by referencing the edge feature points of installed components in real time. It strictly controls edge spacing and angle deviations to meet high-precision requirements. This not only effectively reduces the cumulative deviation caused by early errors, ensuring the flatness and consistency of complex curved building facades, but also significantly improves construction efficiency. Real-time corrections reduce the number of hoisting adjustments and rework, shortening the hoisting time of a single piece of special-shaped curved glass.

[0076] In some embodiments, based on the deviation direction, deviation amount and deviation angle, an adjustment strategy library for the operating parameters of the lifting equipment is constructed, and the adjustment strategy library contains the hook movement direction, cable length adjustment amount, and lifting speed adjustment value corresponding to different deviation combinations; based on the relative position deviation value, a progressive adjustment strategy with a dynamic iteration mechanism is adopted: based on the adjustment strategy library and the dynamic adjustment priority, the hook movement direction, cable length adjustment amount, and lifting speed adjustment value of the special-shaped curved glass during the lifting process are dynamically adjusted. During the adjustment process, the aerial posture of the special-shaped curved glass is continuously acquired, the special-shaped curved glass lifting simulation information set is dynamically updated, and compared with the coordinates of the installation end point of the special-shaped curved glass, the subsequent deviation trend of the special-shaped curved glass during the lifting process is intelligently predicted, and the hook movement direction, cable length adjustment amount, and lifting speed adjustment value are iteratively adjusted to form a closed-loop feedback adjustment mechanism until the deviation of the special-shaped curved glass is within the allowable direction deviation threshold and the allowable angle deviation threshold, and an intelligent lifting precise positioning construction plan report is output.

[0077] The adjustment strategy library can be a pre-built set of parameter mappings that stores hook movement directions, cable length adjustments, and lifting speed adjustments corresponding to different deviation combinations. A dynamic iteration mechanism can be an adaptive adjustment logic that continuously updates the deviation prediction model by collecting lifting posture data in real time. A progressive adjustment strategy can be a control method that reduces deviations in stages, following the principle of "rough adjustment first, then fine adjustment." A closed-loop feedback adjustment mechanism can achieve precise control through a cyclical process of "deviation detection - parameter adjustment - state verification."

[0078] Specifically, in prefabricated building construction, the hoisting of irregularly shaped curved glass faces severe and multiple technical challenges. The unique shape of irregularly shaped curved glass, along with its uneven curvature radius and thickness distribution, causes the center of gravity to dynamically shift during hoisting. This provides technical support for addressing these issues. The specific implementation process is as follows: Using multi-body dynamics coupled finite element analysis technology, modeling is performed for different combinations of irregularly shaped curved glass geometric parameters, hoisting equipment parameters, and environmental parameters. The motion and force conditions of the glass and hoisting equipment under various deviations are simulated. Based on these simulation results, the corresponding hook movement direction, cable length adjustment, and hoisting speed adjustment values ​​are determined, providing theoretical data support for the strategy library. Numerous irregularly shaped curved glass hoisting simulation experiments and actual engineering tests are conducted in real-time on-site environments. By setting variables such as different glass shapes, hoisting equipment parameters, and environmental conditions, the deviations encountered in each experiment or actual operation, as well as the corresponding effective adjustment measures, are recorded. According to the deviation direction, deviation amount and deviation angle of the special-shaped curved glass components in the absolute deviation information, the corresponding parameters are retrieved from the adjustment strategy library, and the corresponding adjustment parameters of the hook, cable and lifting speed are accurately retrieved. The adjustment process performs related operations through the servo motor and variable frequency motor; each time an adjustment is completed, data is collected in real time with the help of laser targets, 3D scanners, and inclination sensors, the lifting simulation information set is updated, the deviation trend is predicted and the adjustment parameters are iteratively optimized; when the deviation amount is stable within the allowable deviation threshold, the adjustment process records, equipment operating parameters, quality verification results and other information are automatically integrated to generate a construction plan report.

[0079] Through this solution, the dynamic adjustment mechanism is utilized to improve the positioning accuracy of the hoisting of special-shaped curved glass and reduce the rework rate. At the same time, closed-loop feedback is used to achieve "one-time hoisting in place", which improves construction efficiency and shortens construction period compared with existing methods. In this process, the cost of secondary hoisting, component damage and manual calibration is effectively reduced, the overall construction cost is reduced, and the safety risk of high-altitude operations is reduced.
