It mainly establishes a three-dimensional model as a refined model with high model accuracy requirements. The modeling process meets the modeling requirements and determines the installation construction sequence of each steel structure member. Large steel components should be constructed first, and then small steel components. Then, simulation is performed according to the actual situation on site. The actual construction situation is simulated in advance to facilitate the control of the construction site. BIM technology is applied to the construction of irregular curved steel structure, which solves the problem of irregular curved steel structure construction, effectively improves the construction efficiency of irregular curved steel structure, and brings significant benefits to engineering construction. Although the above patent solves the problem of BIM model construction of steel structure data, the following problems still exist in actual operation:

[0004] 1. The data of the single-layer spherical lattice shell steel structure was not collected and modeled in a targeted manner, resulting in poor accuracy of the three-dimensional model data of the single-layer spherical lattice shell steel structure.

[0005] 2. The construction plan was not formulated with maximum efficiency based on a complete three-dimensional model, which resulted in the construction workers being unable to carry out effective construction according to the formulated plan.

[0006] 3. The construction site data was not monitored in real time, and no effective construction quality assessment was conducted based on the construction situation, resulting in abnormalities in the construction process that could not be promptly checked. Summary of the invention

[0007] The purpose of the present invention is to provide a single-layer spherical grid shell steel structure construction method based on BIM technology. Through performance analysis and efficiency analysis, the work efficiency of construction equipment and personnel can be evaluated, and then resource allocation can be optimized. The real-time collection and analysis of structural performance data and quality control data can enable quality problems in the construction process to be discovered and handled in a timely manner. When the risk threshold of the target real-time construction data is higher than the preset risk threshold critical point, the early warning mechanism can be quickly activated to effectively avoid further expansion of construction risks. By performing collision and overload detection on construction equipment, the safety of construction equipment during operation can be ensured, and safety accidents caused by equipment failure can be reduced.

[0099] The three-dimensional model is constructed based on the basic data of the single-layer spherical lattice shell steel structure in S1, including:

[0100] The basic data of the single-layer spherical lattice shell steel structure include components, supports, construction equipment and auxiliary equipment;

The construction equipment includes tower cranes, through-type hydraulic jacks, long-arm truck cranes and total stations. The auxiliary equipment includes hangers, steel strands, strain sensors and prisms.

[0102] Use the BIM model to construct a three-dimensional model of the basic data of the single-layer spherical lattice shell steel structure;

[0103] Import the basic data of the single-layer spherical lattice shell steel structure into the BIM model to create a node family, wherein the created node family includes a component node family, a support node family, a construction equipment node family and an auxiliary equipment node family;

[0107] The initial steel structure model data after node family adjustment is marked as steel structure model data, and the steel structure model data is generated into a plan view, a stereo view and a section view.

[0108] Specifically, through the three-dimensional modeling of the BIM model, every detail of the single-layer spherical lattice shell steel structure can be accurately simulated, including rods, nodes, supports, construction equipment and auxiliary equipment, so that potential design conflicts can be discovered and resolved in the design stage, and the design accuracy can be improved. At the same time, three-dimensional modeling has greatly accelerated the design speed and improved the design efficiency. The BIM model not only contains geometric information, but also integrates attribute information such as materials, manufacturers, and costs, which makes the planning and coordination work before construction more efficient. Through the BIM model, the construction process can be simulated, the difficulties and potential problems in the construction can be predicted, countermeasures can be formulated in advance, and the construction sequence and resource allocation can be optimized. The BIM model not only contains geometric information, but also integrates attribute information such as materials, manufacturers, and costs, which makes the planning and coordination work before construction more efficient.

Construction personnel can quickly locate the construction site based on the BIM model, understand the construction requirements, and improve construction efficiency and quality. The BIM model can easily query structural information, equipment location, maintenance records, etc., providing convenient and efficient information support for operation and maintenance management.

[0109] Carry out construction simulation for the steel structure model data in S2, and conduct risk analysis based on the construction simulation results, including:

[0110] The construction phase distribution is carried out according to the steel structure model data, and the construction phase distribution includes foundation construction, main structure construction, support installation construction and equipment installation construction;

[0111] Assign timelines to distributed construction phases and associate construction equipment, materials, and personnel with corresponding construction projects;

[0112] After the timeline allocation and association are completed, the steel structure model data of each construction stage is simulated and animated, wherein the simulated animation construction is to use animation software to make animation models of the steel structure model data after the timeline allocation and association are completed, and render the made animation models;

[0113] After the animation model rendering is completed, the animation simulation model data of the steel structure model data is obtained.

[0114] Specifically, real-time monitoring of the running process of the animation model rendering and determining the running quality of the animation model rendering include:

[0115] Real-time monitoring of operating parameters during the animation model rendering operation; wherein the operating parameters include artifact area and edge smoothness;

[0116] The image distortion evaluation coefficient is obtained by using the image distortion degree corresponding to the rendered animation part completed in each unit time;

[0117] Comparing the image distortion evaluation coefficient with a preset distortion evaluation coefficient threshold;

[0118] When the image distortion evaluation coefficient exceeds a preset distortion evaluation coefficient threshold, the operation parameter is retrieved;

[0119] Obtaining rendering quality evaluation parameters using the artifact area and edge smoothness included in the operating parameters combined with an image distortion evaluation coefficient;

[0120] The rendering quality evaluation parameter is obtained by the following formula:

[0121]

[0122] Wherein, F represents the rendering quality evaluation parameter; F0 represents the preset evaluation parameter reference value; R represents the image distortion evaluation coefficient; n represents the number of unit times experienced by the rendering, and the unit time is 1s; A fi A represents the artifact area generated in the rendering sub-area corresponding to the i-th unit time; i A represents the area of ​​the rendering sub-region in the i-th unit time; s Indicates the rendering area of ​​the entire animation model that needs to be rendered; P i represents the edge smoothness of the i-th unit time; P c Indicates the preset edge smoothness reference value; S c Indicates a preset similarity reference value;

[0123] Comparing the rendering quality evaluation parameter with a preset quality evaluation parameter threshold;

[0124] When the rendering quality evaluation parameter is lower than a preset quality evaluation parameter threshold, it is determined that there is an operation quality abnormality in the animation model rendering operation, and a rendering quality abnormality alarm is issued.

[0125] The technical effect of the above technical solution is: by real-time monitoring of the operating parameters (such as artifact area and edge smoothness) during the rendering of the animation model, the technology can dynamically track the status of the rendering process and ensure immediate feedback on the rendering quality. Combining multiple dimensions such as image distortion evaluation coefficient, artifact area, edge smoothness, etc., the technology can more comprehensively evaluate the rendering quality. This multi-dimensional judgment method can more accurately reflect the overall rendering quality than a single indicator.

[0126] By comparing the image distortion evaluation coefficient with the preset distortion evaluation coefficient threshold, and calling the operating parameters for further quality evaluation when the threshold is exceeded, this technology can accurately detect anomalies in the rendering process, thereby avoiding the accumulation and amplification of quality problems. The rendering quality evaluation parameters are calculated using a formula, which not only takes into account image distortion, artifact area and edge smoothness, but also multiple factors such as rendering time and rendering area, making the quality evaluation more quantitative and objective. When the rendering quality evaluation parameters are lower than the preset quality evaluation parameter threshold, the technology can automatically trigger the alarm mechanism and promptly notify relevant personnel to handle it, thereby effectively reducing the occurrence and impact of quality problems. Through real-time monitoring and dynamic evaluation, the technology can also provide data support for optimizing the rendering process and improving rendering efficiency and quality. For example, rendering parameters can be adjusted, algorithms can be optimized, or computing resources can be increased based on the evaluation results.

[0127] In summary, this technical solution realizes comprehensive monitoring and quality judgment of the animation model rendering process through real-time monitoring, multi-dimensional evaluation, precise anomaly detection, quantitative evaluation parameters and automated alarm mechanism, effectively improving the rendering quality and efficiency.

[0128] Specifically, the image distortion evaluation coefficient is obtained by using the image distortion corresponding to the rendered animation part completed per unit time, including:

[0129] Extract the rendering animation part completed in each unit time as the rendering sub-area; wherein the unit time is 1s;

[0130] Extracting the animation model before rendering corresponding to the rendering sub-region that completes rendering in each unit time as the model sub-region;

[0131] Comparing the similarity of line positions between the rendering sub-region and the model sub-region to obtain a similarity value;

[0132] Obtaining an image distortion evaluation coefficient using a similarity value corresponding to the rendering sub-region and the model sub-region that complete rendering in each unit time;

[0133] The image distortion evaluation coefficient is obtained by the following formula:

[0134]

[0135] Where R represents the image distortion evaluation coefficient; n represents the number of unit times experienced by rendering; S i S represents the similarity value between the rendering sub-region and the model sub-region in the i-th unit time; pi-1 represents the similarity value between all rendered sub-regions rendered before the i-1th unit time and their corresponding model sub-regions; Sc Indicates the preset similarity reference value; A i A represents the area of ​​the rendering sub-region in the i-th unit time; s Indicates the rendering area of ​​the entire animation model that needs to be rendered; A wi-1 Indicates the area and value of all rendering sub-regions that were rendered before the i-1th unit time.

[0136] The technical effect of the above technical solution is: by taking the part of the rendered animation completed in each unit time as the rendering sub-area, and comparing the similarity of the line positions with the animation model (model sub-area) when no rendering is performed, this technology can accurately evaluate the rendering quality of each time period, especially the degree of image distortion.

[0137] When calculating the image distortion evaluation coefficient, this technical solution not only considers the similarity value of the current unit time, but also considers the cumulative effect of the similarities of all previous unit times (through S pi-1 , A wi-1 This comprehensive consideration makes the evaluation results more comprehensive and accurate. By taking the area of ​​the rendered sub-region per unit time and the sum of the areas of all previously rendered sub-regions as weight factors, this technology can more reasonably reflect the impact of different regions on the overall image distortion evaluation. Larger regions contribute more to the evaluation results, which is in line with the actual situation.

[0138] Since this technical solution is carried out in real time, it can dynamically reflect the image distortion during the rendering process. Once the image distortion evaluation coefficient is found to be abnormal, measures can be taken immediately to adjust it to avoid the accumulation and amplification of quality problems. Through refined image distortion evaluation and dynamic adjustment, this technical solution helps to improve the rendering quality. Especially in situations where high-precision rendering is required (such as animation, movie special effects, etc.), this technology can ensure the accuracy and consistency of the rendering results. This technical solution can also provide data support for optimizing the rendering process. By analyzing the image distortion evaluation coefficients in different time periods, the bottlenecks and potential problem points in the rendering process can be found, so as to optimize and improve them in a targeted manner.

[0139] In summary, this technical solution achieves comprehensive monitoring and accurate evaluation of image distortion during animation model rendering through refined image distortion evaluation, comprehensive consideration of multiple factors, area-weighted processing, dynamic adjustment and real-time monitoring, which helps to improve rendering quality and optimize the rendering process.

[0141] Safety analysis is to analyze the stress and deformation of the animation simulation model data, analyze the stability of the structure based on the stress and deformation, and conduct collision and overload detection on the construction equipment;

[0142] Progress analysis is to judge the rationality of the steps in the construction phase timeline and the efficiency of the construction equipment;

[0144] Divide the animation simulation model data into risk ranges based on safety analysis, schedule analysis and cost analysis;

[0145] Confirm the risk areas in the animation simulation model data according to the divided risk range, and adjust the risk areas;

[0146] After risk adjustment, low-risk animation simulation model data are obtained, and the low-risk animation simulation model data are marked as standard construction simulation data.

[0147] Specifically, BIM technology can accurately simulate the stress and deformation of steel structures during the construction process, helping engineers predict the stability of the structure in advance, thereby avoiding structural safety problems that may arise in actual construction. By performing collision and overload detection on construction equipment, the safety of construction equipment during operation can be ensured, reducing safety accidents caused by equipment failure. BIM technology can clearly display the timeline of each construction stage, enabling project managers to reasonably arrange the construction sequence and improve construction efficiency. At the same time, by judging the rationality of the timeline, potential construction bottlenecks can be discovered and resolved in a timely manner. Through simulation animation, the use of construction equipment can be intuitively seen, helping managers optimize equipment scheduling and improve equipment utilization efficiency. BIM technology can simulate and analyze materials, equipment and labor costs in detail, helping managers find the key points of cost optimization, thereby reducing overall construction costs. By simulating the construction process in advance, potential problems in the design plan can be discovered and corrected, reducing rework and waste in actual construction. The information in the BIM model can be retrieved and viewed at any time, providing a convenient information sharing and communication platform for project managers, construction personnel and other stakeholders, thereby improving overall construction efficiency. The three-dimensional coordinate information in the BIM model can help construction personnel accurately locate the position and size of each construction element to ensure the accuracy and consistency of construction.

[0148] In order to solve the problem in the prior art that the construction plan is not formulated with the most efficiency based on the perfect 3D model, which results in the construction personnel being unable to carry out effective construction according to the formulated plan, please refer to Figure 1 and Figure 2, this embodiment provides the following technical solutions:

[0150] Formulate the on-site construction plan framework based on the standard construction simulation data, where the on-site construction plan framework includes construction methods, construction sequence, quality standards and safety measures;

[0151] Confirm the construction methods for foundation construction, main structure construction, support installation and equipment installation based on standard construction simulation data, and develop the construction sequence and schedule based on the timeline of the construction phase;

[0152] And formulate the control parameters of the connection points between each equipment and each structure according to the standard construction simulation data;

[0153] Construction schedule development according to the established construction sequence and schedule and control parameters of each equipment and connection point between each structure;

[0154] Allocate construction personnel according to the established construction schedule;

[0155] After the construction personnel are assigned, the overall construction plan and construction personnel for the single-layer spherical lattice shell steel structure are obtained and marked as standard on-site construction data.

[0156] Specifically, the construction plan framework covers multiple aspects such as construction methods, construction sequence, quality standards and safety measures, ensuring the comprehensiveness and systematicness of the construction process. The construction plan can be visualized through a three-dimensional model, allowing construction personnel and managers to understand the construction process and key points more intuitively. Confirming the construction method based on standard construction simulation data can ensure the scientificity and accuracy of the construction method and reduce uncertainty and errors in the construction process. When formulating the construction sequence and schedule, simulation and optimization through BIM technology can reasonably arrange the construction process, reduce unnecessary waiting time and resource waste, and improve construction efficiency. BIM technology can accurately calculate the location of each equipment and each structure. The control parameters of the connection points between them ensure the stability and safety of the connection. The construction schedule based on BIM technology can be dynamically adjusted. The construction plan can be adjusted in time according to the actual situation on site to ensure the smooth progress of the construction. The simulation of the construction progress through BIM technology can optimize resource allocation, reduce resource waste, and improve resource utilization efficiency. Construction personnel can be reasonably allocated according to the construction progress and project volume to ensure that each construction stage has sufficient human resource support to avoid waste or shortage of human resources. The simulation and prediction functions of BIM technology can be used to discover possible problems and risks in the construction process in advance, and formulate corresponding prevention and response measures to ensure the smooth progress of the construction process.

[0157] In order to solve the problem in the existing technology that there is no real-time monitoring of construction site data and no effective construction quality assessment based on the construction situation, which leads to the problem that abnormalities in the construction process cannot be promptly checked, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions:

[0158] S4 monitors the construction site in real time based on standard on-site construction data, and collects key data during the construction process, including:

[0159] The construction personnel carried out the construction of the single-layer spherical lattice shell steel structure according to the standard on-site construction data;

[0160] Confirm the monitoring target before the construction of the single-layer spherical lattice shell steel structure;

[0161] Monitoring targets include construction process, equipment, materials and personnel, and monitoring equipment will be deployed, including cameras, sensors and mobile devices. Sensors include strain sensors and temperature and humidity sensors;

[0162] The BIM collaborative platform is used to collect real-time construction data through monitoring equipment.

[0163] After the real-time construction data collection is completed, data analysis is carried out, including comparative analysis, performance analysis and efficiency analysis;

[0164] Comparative analysis is to compare the standard on-site construction data with the actual construction data and analyze the deviations;

[0165] Performance analysis is to conduct structural analysis on structural stress and deformation data;

[0166] Efficiency analysis is to analyze the work efficiency of construction equipment and construction personnel;

[0167] According to the analysis results, key data in the actual construction data are obtained, including structural performance data, construction progress data, quality control data, safety monitoring data, cost management data and equipment operation data;

[0168] And mark the acquired key data as target real-time construction data.

[0169] Specifically, through monitoring equipment such as cameras, sensors and mobile devices, the construction site is monitored in all directions and in real time, which can instantly capture key data in the construction process, realize accurate control of construction progress and real-time monitoring of quality. This refined management helps to discover potential problems in a timely manner and take corrective measures quickly. It conducts in-depth analysis of the construction data collected in real time, including comparative analysis, performance analysis and efficiency analysis, and provides strong data support for the project management team. This data-based decision-making method is more scientific and objective, which helps to improve the accuracy and efficiency of decision-making. The monitoring targets cover personnel, equipment, materials and construction processes. In particular, through the real-time collection and analysis of safety monitoring data, safety hazards can be discovered in a timely manner and the occurrence of safety accidents can be prevented. This is of great significance for ensuring the safety of construction personnel and reducing accident losses. Through performance analysis and efficiency analysis, the work efficiency of construction equipment and personnel can be evaluated, and resource allocation can be optimized. The real-time collection and analysis of structural performance data and quality control data enables quality problems in the construction process to be discovered and handled in a timely manner. This helps ensure that the quality of the single-layer spherical lattice shell steel structure construction meets the design requirements and relevant standards. By using the BIM collaborative platform to achieve data sharing and collaboration, different professional teams can communicate and coordinate based on the same set of data models, improving the coordination and efficiency of work. This helps reduce errors and delays caused by poor information communication.

[0170] Analyze the real-time construction data of the target in S5, and make assessments and early warnings based on the analysis results, including:

[0171] Import the target real-time construction data into the BIM collaboration platform and integrate it with the standard on-site construction data;

[0172] After data integration is completed, data comparison and analysis are carried out, and quality assessment of the target real-time construction data is carried out based on the analysis results. The higher the degree of overlap between the target real-time construction data and the standard on-site construction data during data comparison, the higher the quality level and the lower the risk. If the degree of overlap is lower, the quality level is lower and the risk is higher.

[0173] When the risk threshold of the target real-time construction data is higher than the preset risk threshold critical point, the early warning mechanism is activated for the target real-time construction data;

[0174] According to the corresponding risk items in the target real-time construction data, an early warning alarm is issued and an early warning prompt is given on the display terminal.

[0175] Specifically, by importing the target real-time construction data into the BIM collaborative platform and integrating it with the standard on-site construction data, rapid centralized data processing can be achieved. The powerful data processing capabilities of the BIM platform make this process efficient and accurate, laying a solid foundation for subsequent data comparison and analysis. After the data integration is completed, the data comparison and analysis can accurately reflect the degree of compliance between the actual construction situation and the standard construction requirements. By comparing the overlap between the target real-time construction data and the standard on-site construction data, the construction quality level can be intuitively judged, so as to timely discover potential quality problems. When the risk threshold of the target real-time construction data is higher than the preset risk threshold critical point, the system can quickly start the early warning mechanism. This immediate response mechanism helps to take corresponding measures when the problem is first revealed, effectively avoid further expansion of construction risks, and ensure construction safety and progress. According to the corresponding risk items in the target real-time construction data, early warning alarms are issued and early warning prompts are issued on the display terminal. This method enables construction management personnel to quickly locate the problem and understand the nature and severity of the problem. This intuitiveness helps to improve the efficiency of construction management and ensure that problems are solved in a timely and effective manner. The data analysis and early warning mechanism based on BIM provides a scientific decision-making basis for construction management personnel. Through in-depth analysis and mining of construction data, we can more accurately evaluate the current construction status, predict future development trends, and provide strong support for the adjustment and optimization of construction plans.
