Description

Technical Field

[0002] In the existing technology, in the field of architectural engineering design today, two-dimensional software design occupies a dominant position. However, with the rapid development of urbanization, this traditional two-dimensional graphic design method has gradually exposed many problems and is difficult to meet the various needs of urban development. On the one hand, two-dimensional design has obvious shortcomings in the engineering construction stage. It cannot provide the three-dimensional form of any part in time according to project requirements, which brings certain troubles to the construction process. It is difficult for construction personnel to intuitively understand the complex parts of the building structure, and the guiding role of construction is limited. For example, in the construction of some key nodes, the two-dimensional drawings may not be able to clearly show the connection relationship and spatial position between the components, which may lead to misunderstandings and operations during the construction process, affecting the construction progress and quality.

[0003] On the other hand, two-dimensional design cannot play an effective role in the project delivery and operation and maintenance stage. Two-dimensional design cannot express and store all the information of the building in a timely manner, and it is difficult to efficiently connect with the construction of digital cities in the later stage. This is undoubtedly a major defect in today's increasingly important digital management and operation and maintenance. The inability to achieve real-time monitoring and energy management of the project increases the cost of operation and maintenance, and is not conducive to the intelligent development of the city. Especially in the emerging digital construction, digital management and intelligent operation and maintenance of cities, the limitations of two-dimensional graphics are becoming more and more prominent. It cannot meet the needs of all-round and multi-angle display and analysis of buildings, nor can it provide sufficient support for the city's intelligent decision-making. At this stage, a method and system for the simultaneous delivery of two and three dimensions based on three-dimensional design is needed. Summary of the invention

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] Example 1 Reference Figure 1 , a method for synchronous delivery of two and three dimensions based on three-dimensional design in this embodiment includes: Obtain formal program documents based on initial project information and design brief; Establish a preliminary 3D model based on the formal scheme documents, including establishing the project elevation and axis grid, and establishing the wall, door, window and roof project elements in combination with parametric design technology; Use the preliminary 3D model to conduct preliminary design of the 2D and 3D delivery model, including the use of intelligent annotation when exporting 2D drawings, and combine big data analysis to analyze and predict the material usage of historical projects; Establish a 3D model of the construction drawing based on the 2D and 3D delivery model of the preliminary design, including using virtual reality and augmented reality technology to deepen the project model, and using topology optimization algorithms to deepen the model; Build the final 2D and 3D delivery model based on the 3D model of the construction drawing, including using intelligent conversion algorithms to adjust the format and content of the drawings according to different usage requirements and standards; The 3D model is extended based on the final 2D and 3D delivery model, including extension in the construction phase and extension in the project delivery and operation phase.

[0021] Specifically, a method for synchronous delivery of two-dimensional and three-dimensional designs based on three-dimensional designs includes the following steps: S1. Obtain the formal plan documents based on the initial project information and design brief; Based on the initial project information and design brief, the architectural, structural and electromechanical professionals review the project design plan and eventually form a formal plan document.

[0022] S2. Establish a preliminary 3D model based on the formal plan documents, including establishing the project elevation and axis grid, and establishing the wall, door, window and roof project elements in combination with parametric design technology; The point cloud data of the object surface is obtained through 3D laser scanning. 3D laser scanning mainly measures the shape and size of the object accurately by obtaining the point cloud data of the object surface. When combined with BIM, the point cloud registration algorithm is used to match the scanned point cloud data with the BIM model to detect deviations in the construction process. The point cloud registration algorithm uses an iterative closest point algorithm. Its basic idea is to find the optimal transformation matrix between two point cloud sets through continuous iteration to minimize the distance between corresponding points. Assuming point cloud A and point cloud B, a point in point cloud A , a point in point cloud B The goal is to find a transformation matrix T so that point cloud A coincides with point cloud B as much as possible after transformation. The transformation matrix T includes the rotation matrix R and the translation vector t. , the objective function of the iterative closest point algorithm is expressed as: , Among them, t represents the translation vector, which represents the displacement of a set of points in space, n represents the total number of points in point cloud A and point cloud B, represents the coordinates of the i-th point in point cloud A, Represented as the coordinates of the i-th point in point cloud B, Represents a point in point cloud A The coordinates rotated by the rotation matrix R are optimized through continuous iteration to minimize the objective function. In construction projects, 3D laser scanning can be used to scan the constructed parts, align the point cloud data with the BIM model, and calculate the deviation between the actual construction and the design, so as to adjust the construction plan in time.

[0023] Then, the finite element analysis algorithm is used to accurately simulate and optimize the mechanical properties of the structure. For a plane structure, the equilibrium equation is: , in, , and are the normal stress in the x-direction, the normal stress in the y-direction and the shear stress, and is the body force component. By discretizing the structure into a finite number of elements and calculating the node displacement in each element, the displacement in each element can be expressed as the node displacement: , , in , is the displacement component, is the shape function, , is the node displacement. According to the relationship between strain and displacement and the constitutive relationship between stress and strain, the unit stiffness matrix is ​​obtained. , and then assemble the stiffness matrices of all units to obtain the overall stiffness matrix K to solve the overall equilibrium equation , where d is the node displacement vector and F is the node force vector, the displacement and stress distribution of the structure can be obtained.

[0024] S3. Use the preliminary 3D model to conduct preliminary design of the 2D and 3D delivery model, including the use of intelligent annotation when exporting 2D drawings, and combine big data analysis to analyze and predict the material usage of historical projects; When using the BIM collaborative platform to export two-dimensional drawings, intelligent annotation technology is used to automatically identify and annotate key dimensions and parameters to improve the readability and accuracy of the drawings. Combined with big data analysis technology, the material usage of historical projects can be analyzed and predicted. In the preliminary design two- and three-dimensional delivery stage, big data analysis technology can be used to analyze and predict the material usage of historical projects.

[0025] Assume that the material usage data of the historical project is ,in is the material consumption vector of the i-th project. A regression analysis algorithm is used to establish a relationship model between material consumption and project characteristics. The regression coefficient is determined by training historical data, and the material consumption is predicted based on project characteristics. The relationship model is expressed as: , in, Expressed as material usage, Expressed as project features, Expressed as regression coefficient, It is represented as an error term.

[0026] S4. Establish a 3D model of the construction drawing based on the 2D and 3D delivery model of the preliminary design, including using virtual reality and augmented reality technologies to deepen the project model, and using topology optimization algorithms to deepen the model; Virtual reality mainly creates a virtual environment for users to immerse themselves in for design review. In virtual reality, a three-dimensional rendering algorithm is used to present realistic scenes. This embodiment uses a three-dimensional rendering algorithm, and its basic principle is to simulate the propagation of light in the scene and calculate the interaction between light and objects to determine the color of pixels. The three-dimensional rendering algorithm is expressed as: , in, Represented as the color of the pixel, Represented as the color and intensity of the light source, Represented as the material properties of the object, Expressed as the reflection and refraction coefficients of light on the surface of an object.

[0027] Augmented reality is to overlay virtual information onto real scenes for construction guidance. The tracking and registration algorithm in augmented reality is used to determine the position and direction of virtual information in real scenes. Commonly used tracking and registration algorithms include landmark-based tracking and registration and natural feature-based tracking and registration.

[0028] In construction projects, virtual reality is used for immersive design review, allowing designers to better experience the effects of design solutions. Augmented reality can integrate BIM models with actual scenes at the construction site. Construction workers can view virtual construction guidance information through mobile phones or tablets to improve construction accuracy and efficiency.

[0029] When designing beams, columns, stairs, and mechanical and electrical openings, topology optimization algorithms can be used to achieve the optimal distribution of materials while meeting the structural performance requirements. The formula can be expressed as: objective function f (x) = min {material volume}, constraint g (x) ≤ 0 (where g (x) is the structural performance constraint).

[0030] Finally, when further designing the equipment room, branch pipes of each system, and terminal points, the Internet of Things (IoT) technology is used to achieve real-time monitoring and control of the equipment. For example, the operating parameters of the equipment are collected through sensors, and the data is transmitted to the management platform through wireless networks to achieve remote monitoring and fault diagnosis.

[0031] S5. Build the final 2D and 3D delivery model based on the 3D model of the construction drawing, including adjusting the format and content of the drawing according to different usage requirements and standards; The requirements for two-dimensional drawings vary in different stages and scenarios of construction projects. For example, in the design review stage, drawings that highlight the design concept and overall layout may be needed, focusing on showing the appearance and spatial relationship of the building; while in the construction stage, construction personnel are more concerned with specific dimensioning, construction technology and material information. The format and content of the drawings are adjusted to obtain the geometric shape information of the building components from the three-dimensional model, such as point coordinates, line vectors, surface normal vectors, etc. For a three-dimensional point, its coordinate value is the basic geometric information, and the size parameters of the component, such as length, width, height, etc., are calculated, and information such as material properties, component number, and system to which it belongs are extracted. This information is stored in the three-dimensional model in text or a specific data format, and the annotation content is generated based on the extracted geometric information and attribute information. For example, for a wall component, its length, height, thickness and other dimensional information, as well as material, number and other attribute information are annotated, and the position and style of the annotation are determined according to certain rules. For example, the dimension annotation is usually located near the edge of the component, and the text size and line type can be adjusted according to the scale and importance of the drawing. According to different component types and attributes, corresponding symbols and legends are generated.

[0032] S6. Extend the 3D model based on the final 2D and 3D delivery model, including extension during the construction phase and extension during the project delivery and operation phase.

[0033] When viewing component attribute information and extracting material lists, blockchain technology is used to ensure data security and non-tamperability. For a component attribute information M, its hash value H(M) is calculated, and the authenticity of the information is verified by comparing the recalculated hash value with the hash value stored on the blockchain. During the construction phase, when using the three-dimensional model for sub-item division and process arrangement, project management software is used to achieve visualization and dynamic control of the construction progress. The construction schedule is displayed through the Gantt chart, the key process and construction period of the project are determined by the critical path method, and the bill of quantities of each sub-item is extracted in combination with the three-dimensional model, including the quantity of civil engineering materials, the quantity of steel bars, the quantity of electromechanical pipelines, the quantity of equipment, etc., to assist in business procurement, and the three-dimensional digital model is used for digital operation and maintenance. The goal is to find a hyperplane so that different types of equipment operation data samples can be correctly separated. By training historical data, the parameters of the hyperplane are determined, and fault judgment is performed on new operation data samples. Energy use is partitioned according to monitoring data, and energy distribution and management are carried out reasonably to reduce operation and maintenance costs, truly achieving perfect integration with digital cities.
