[0031] Example 1:

[0032] like Figure 1As shown, this embodiment provides a digital design and virtual construction method for construction projects. This method is applicable to a three-dimensional construction system. The system includes a modeling data optimization unit, which uses a cloud interactive terminal to provide optimization of the modeling process and parameter settings for building projects; a building index adjustment and optimization unit, which uses the historical range of various indicators of the building project and the threshold of indicator changes under different environments to adjust and optimize the building index data; a building index adaptation unit, which optimizes the responsible building indicators, lighting parameters, modeling parameters, and various three-dimensional model parameters; and has the ability to check, cluster, evaluate, and adaptively adapt lighting parameters for adjusted building indicators; a modeling comprehensive management unit, which realizes the three-dimensional data modeling of the building project with adjusted building indicators according to lighting parameters, modeling parameters, and modeling process; and a modeling method processing unit, which processes the three-dimensional data of the building project using a spatial modeling method with polygon meshes. The method includes steps S100, S200, S300, and S400.

[0033] Step S100: Utilize a knowledge graph to identify changes in building indicators due to architectural design requirements or non-human factors, thereby enabling the verification, clustering, and updating of building indicator data. The latest building indicator results are then sent to the basic data processing unit. The knowledge graph comprises: a benchmark for adjusting changes in architectural engineering link relationships, a benchmark for synchronizing material parameter rendering effects, and a benchmark for verifying and clustering building indicators. Specifically, the benchmark for adjusting changes in architectural engineering link relationships defines the direction, magnitude, type, location distribution, and ablation properties of the stress positions in various architectural engineering link relationships, used to detect changes in architectural engineering and identify altered building indicators. The benchmark for synchronizing material parameter rendering effects defines the risk sources, controllability, types, and location distribution of synchronized rendering effects for different modeling risk data, used to detect changes in building indicator data related to modeling risks. The benchmark for verifying and clustering building indicators defines the criteria for identifying identical building indicators and the clustering principles, used to determine whether building indicators have been included in management and whether the optimized building indicator list data needs to be updated.

[0034] Step S200: Modify the list of building indicators, establish a benchmark using lighting parameters, and synchronously complete the establishment or update of lighting parameters, and send the latest lighting parameter information to the modeling and integrated management unit.

[0035] Step S300: Extract the lighting parameter information and establish the relationship between lighting parameters, modeling parameters, modeling process and modeling task based on the modeling task operation benchmark;

[0036] Step S400: Upon receiving the modeling task execution instruction, connect the building indicators according to the lighting parameter information and perform data modeling. At the same time, send the modeled raw data to the modeling method processing unit. Load the data space modeling method according to the lighting parameter information, complete the processing of the raw data, and save the data according to the set data three-dimensional model parameters.

[0037] Secondly, in this embodiment, before using knowledge graphs to identify changes in architectural design requirements or non-human factors in architectural indicators, it is necessary to construct a corresponding 3D model based on BIM design software. The specific construction method can be as follows:

[0038] Step S101: Use BIM design software to perform BIM 3D modeling of the building project and generate a 3D BIM model;

[0039] Step S102: Use sensors to collect real-time monitoring data of the construction project to obtain monitoring data, and encrypt the monitoring data to generate encrypted real-time monitoring data.

[0040] Step S103: Receive encrypted real-time monitoring data using the BIM data server, decrypt the encrypted real-time monitoring data to obtain the original real-time monitoring data, perform data filtering and cleaning on the original real-time monitoring data, and generate standard real-time monitoring data.

[0041] Step S104: Integrate the standard real-time monitoring data with the 3D BIM model to generate a comprehensive BIM model data view. Perform data statistics and analysis on the BIM model data view to generate key information guidance.

[0042] Secondly, in this embodiment, the specific implementation method of step S101, which involves using BIM design software to perform BIM 3D modeling of the building project and generate a 3D BIM model, is as follows:

[0043] Step S1011: Obtain the design drawings and standardized component parameters of the building project, and use BIM design software to create a 3D building model of the design drawings.

[0044] Step S1012: Add architectural elements to the 3D building model using standardized component parameters to generate a detailed 3D building model. Then, use the geometric inspection tool of the BIM design software to check and repair errors in the detailed 3D building model to obtain a three-dimensional BIM model.

[0045] This embodiment utilizes a multi-dimensional adjustment data modeling system for building engineering. By leveraging the historical range of various building engineering indicators and the threshold values ​​for indicator changes under different environments, it achieves automatic adjustment of building indicator changes, data verification, clustering updates, and adaptive adaptation of related data. This solves the problem of low efficiency in traditional building engineering data modeling due to manual data configuration. Furthermore, it automatically incorporates adjusted building indicators into the modeling strategy based on specific conditions to complete data modeling, addressing the inefficiency of traditional building engineering data modeling where lighting parameters, relationships between lighting parameters, and modeling tasks are manually established for each building indicator. Finally, it provides parametric polygonal meshes for parsing the original results, resulting in higher modeling accuracy and wide applicability in the construction field.
