Description

Technical Field

[0001] The present invention relates to the technical field of building modeling, and in particular to an engineering building construction system and method based on 3D modeling. Background Art

[0002] With the increasing development of urbanization, the scale and number of engineering construction are also increasing. This has led to a large amount of construction data being generated in the process of engineering construction project management, such as construction data before, during and after construction. For the construction industry, accurate data analysis is conducive to the control of the entire construction project. The mechanization and automation level of the traditional construction industry is low, and its development urgently needs transformation and upgrading. With the development and gradual maturity of 3D modeling technology, this technology will bring technological innovation to the labor-intensive construction industry. 3D modeling technology is a process of creating three-dimensional object models using computer software. 3D modeling technology can identify design defects before construction, avoid the additional costs caused by later modifications, and allow architects to simulate the performance of buildings under different environmental conditions and perform energy optimization design, which not only meets the requirements of sustainable development, but also reduces operating costs in long-term use. Through 3D models, the construction team can understand the construction details in advance and achieve precise construction. 3D models can also be combined with construction progress management systems to update the construction progress in real time, ensure that each link is completed within the expected time, and significantly improve construction efficiency. In the design stage, through visualization functions, unreasonable design plans can be discovered and adjusted early, thereby avoiding material waste and increased labor costs. During the construction phase, accurate models make actual construction operations smoother, reduce rework rates, and ultimately achieve high returns on the project. Engineering and construction 3D modeling technology is an important means to achieve transformation and upgrading of the construction industry. It is an effective way to solve the problem of efficient, safe, digital, automated, and intelligent construction of buildings. Its research has become a development trend in the construction industry.

[0063] Specifically, the preset period is determined according to the engineering building design data.

[0064] In implementation, the overall construction time is determined based on the building characteristic data and the building construction data, and the preset period is determined based on the overall construction time. Preferably, the preset period is 1 / 10 to 1 / 30 of the overall construction time.

[0065] a model optimization module, which is connected to the database and the construction data analysis module respectively, and is used to calculate the model data adjustment amount of the three-dimensional design model according to the construction deviation vector and the construction free trend vector to optimize the three-dimensional design model, and update the data in the database;

[0070] See also Figure 2 As shown, it is a structural block diagram of a three-dimensional design model generation module according to an embodiment of the present invention; specifically, the three-dimensional design model generation module includes:

[0071] A city data analysis submodule, which is connected to the database and is used to analyze the city data and determine the regional characteristic data of the engineering building;

[0072] During implementation, the structural characteristics of engineering buildings are preliminarily planned based on urban data so that the engineering buildings meet the requirements of urban geography and urban planning and adapt to the urban climate, thereby determining the regional characteristic data of the engineering buildings. For example, the climate in southern cities is hot and humid with heavy rain and a harmonious natural environment. The design of engineering buildings in the south focuses on ventilation, shading and drainage. The corresponding regional characteristic data can be rainproof building materials, design sculpture art, building colors that are conducive to reflecting sunlight, water systems with rich vegetation, earthquake-resistant structures, etc.

[0073] Specifically, the city data can be input into a preset deep learning model to obtain regional feature data output by the preset deep learning model.

[0074] It is understandable that the actual implementers can obtain a preset deep learning model through training based on the urban data of each engineering building that has passed the qualification inspection in the historical data and the regional characteristic data of each engineering building.

[0075] A building data matching submodule, which is connected to the database and the city data analysis submodule, and is used to match the engineering building design data with the regional feature data to determine the building design data;

[0076] Specifically, the building data matching submodule determines a matching feature vector based on the engineering building design data and the regional feature data, and inputs the matching feature vector into the target neural network model to obtain the building design data output by the target neural network model.

[0077] Specifically, the data corresponding to each feature in the engineering and architectural design data and the regional feature data are used as elements in a matching feature vector to obtain a matching feature vector.

[0078] It should be noted that those skilled in the art know that any neural network model in the prior art that can obtain architectural design data through training of engineering architectural design data and regional feature data falls within the protection scope of the present invention and will not be described in detail here.

[0079] The three-dimensional design model generating submodule is connected to the building data matching submodule and is used to generate a three-dimensional design model of the engineering building according to the building design data.

[0080] It is understandable that any method in the prior art that can generate a three-dimensional design model of an engineering building based on architectural design data falls within the protection scope of the present invention and will not be described in detail herein.

[0081] The three-dimensional design model generation module of the present invention includes a city data analysis submodule, a building data matching submodule and a three-dimensional design model generation submodule. The building design data is determined by matching the regional characteristic data of the engineering building with the engineering building design data, thereby determining the three-dimensional design model, which can improve the model accuracy of the constructed three-dimensional design model.

[0082] See also Figure 3 As shown, it is a structural block diagram of a construction data analysis module according to an embodiment of the present invention; specifically, the construction data analysis module includes:

[0083] A construction deviation determination submodule, which is connected to the three-dimensional design model generation module and the three-dimensional real-time model construction module respectively, and is used to determine the data difference corresponding to each engineering building feature based on the three-dimensional design model and the three-dimensional real-time model, and determine the overall construction deviation based on each of the data differences;

[0084] During implementation, a number of engineering construction features are determined according to the three-dimensional real-time model, and a three-dimensional comparison model is determined based on the several engineering construction features and the three-dimensional design model, and the three-dimensional comparison model partially overlaps with the three-dimensional design model; the engineering construction features corresponding to the three-dimensional real-time model and the engineering construction features corresponding to the three-dimensional comparison model are compared to determine the data differences corresponding to each engineering construction feature, and the overall fluctuation degree of each data difference is determined as the overall construction deviation.

[0085] For example: The engineering building features Y1, Y2, ..., Y j , …, Y m ; The engineering and construction features E1, E2, ..., E corresponding to the three-dimensional comparison model j ,…,E m ; The corresponding data differences are H1, H2, …, H j , …, H m ; where j = 1, 2, ..., m; m is the number of engineering building features; Y j is the jth engineering building feature of the 3D real-time model; E j is the jth engineering building feature of the 3D comparison model; H j =Y j -E j ; then the overall construction deviation Z is: Z=(∑ m j=1 (H j -((∑ m j=1 H j ) / m)) 2 ) / m.

[0086] A construction deviation vector determination submodule, which is connected to the three-dimensional real-time model construction module and is used to determine the construction deviation vector based on the construction variables of the three-dimensional real-time model;

[0087] In the implementation, the construction variables are determined according to several engineering construction features corresponding to the three-dimensional real-time model, and the data differences of each engineering construction feature corresponding to the three-dimensional real-time model and each engineering construction feature corresponding to the three-dimensional comparison model are compared with a preset difference threshold to determine the deviation feature, and the construction deviation vector is determined according to the construction variables corresponding to the deviation feature; wherein, if H j >C, the j-th engineering building feature is determined as a deviation feature; C is the preset difference threshold.

[0088] It is understandable that the actual implementers can determine the preset difference threshold based on the actual situation or the average of the data differences of multiple tests based on the historical data that have passed the acceptance inspection, or determine the preset difference threshold based on the standard range of building tolerances.

[0089] A construction freedom trend vector determination submodule is connected to the database and the three-dimensional real-time model construction module respectively, and is used to determine the construction freedom trend vector based on the changes of the three-dimensional real-time model obtained in a preset period and based on the engineering and architectural design data.

[0090] During implementation, a number of basic engineering construction features and a number of changed engineering construction features are determined according to changes in the three-dimensional real-time model obtained in a preset period (the basic engineering construction features are engineering construction features that exist in all three-dimensional real-time models obtained in a preset period; the changed engineering construction features are engineering construction features newly introduced in each three-dimensional real-time model obtained in a preset period); a basic characteristic equation is constructed according to changes in the basic engineering construction features in a preset period; a force analysis is performed on each changed engineering construction feature, and a number of engineering construction influencing factors are determined in combination with the engineering construction design data (the influencing factors of each changed engineering construction feature are determined in combination with the force analysis and the engineering construction design data, and the engineering construction influencing factors are determined based on each influencing factor); a new basic characteristic equation is determined based on the basic characteristic equation and the several engineering construction influencing factors, and a construction freedom trend vector is determined based on the new basic characteristic equation.

[0091] It should be noted that the basic characteristic equation is generally a mathematical equation (generally a size or shape equation) constructed by force analysis and deformation analysis combined with time changes.

[0092] Specifically, the variation equations of the building characteristics of each infrastructure project are J1, J2, …, J i , …, J n ; then the basic characteristic equation JC=J1+J2+…+J i +…+J n ; Change engineering building features B1, B2, ..., B g , …, B h ; Determine the influencing factors b1, b2, ..., b of each engineering building according to the characteristics of each changing engineering building g , …, b h ; Determine the comprehensive impact factor a=b1×b2×…×b based on the impact factors of each engineering building g ×…×b h ; then the new basic characteristic equation is XC=a×JC; based on the new basic characteristic equation, the construction free trend vector can be determined.

[0093] It is understandable that those skilled in the art know that any method in the prior art that can determine a vector according to an equation falls within the protection scope of the present invention and will not be described in detail herein.

[0094] Where i = 1, 2, ..., n; g = 1, 2, ..., h; h < n; J i is the variation equation of the building characteristics of the ith foundation project, B g is the g-th variable engineering building feature, b g is the engineering construction impact factor corresponding to the g-th changed engineering construction feature.

By determining the overall construction deviation, the construction deviation vector and the construction free trend vector, data support is provided for subsequent model optimization to improve the construction quality of engineering buildings.

[0097] a model data adjustment amount determination submodule, which is connected to the construction data analysis module and is used to calculate the model data adjustment amount of the three-dimensional design model according to the construction deviation vector and the construction free trend vector;

[0098] In implementation, the corresponding deviation adjustment amount is determined according to each construction deviation vector and the construction free trend vector; and the model data adjustment amount of the three-dimensional design model is determined according to the minimum value of each deviation adjustment amount.

[0099] Specifically, the deviation adjustment amount corresponding to each construction deviation vector is determined according to the product of the modulus of each construction deviation vector and the modulus of the construction free trend vector.

[0106] During implementation, the optimized three-dimensional design model is compared with the three-dimensional design model before optimization to determine the optimization adjustment area, and the building feature data and building construction data corresponding to the optimization adjustment area are determined as data to be updated.

[0107] A data updating unit is connected to the database and the update data determining unit respectively, and is used to update the data in the database according to the data to be updated.

[0108] In implementation, the data to be updated is updated according to a preset data updating method, thereby updating the data in the database.

[0109] In actual application scenarios, actual implementers can set preset data update methods based on expert systems or on engineering and construction design data update methods that have passed qualification tests in historical data according to actual conditions. For example: adjusting and updating engineering and construction design data by building a BIM model; adjusting and updating engineering and construction design data by building a digital twin model for simulation.
