Technical Field
The invention belongs to the technical field of building and traffic engineering, and particularly relates to a method for quickly generating a structural directory tree in a management platform based on a BIM (building information modeling) technology.
Background
The BIM technology is rapidly developed in the fields of building and traffic engineering, a computer informatization technology represented by the BIM technology becomes a research and development direction in the building engineering, and a 2016-2020 outline of informatization development of building industry indicates that the latest information technology taking the BIM as a core becomes a core technology for supporting the technology upgrade of the industry, the change of a production mode and the innovation of a management mode. The integrated application of BIM, an enterprise management system and other information technologies is required to be mastered and realized by design units and construction enterprises.
In order to realize management based on component level in BIM technology application, professional structural components need to be expanded in a directory tree form, so that a user can conveniently position the components, and meanwhile, a one-to-one mapping relation is formed between the components and component categories, but the application in the aspect is rarely realized in the prior art and the prior use.
Disclosure of Invention
The invention aims to provide a method for quickly generating a structure directory tree in a management platform based on a BIM technology, which is used for positioning a component and forming a one-to-one mapping relation with component categories at the same time, so that the problem of quickly generating the structure directory tree by the management platform is solved.
The technical scheme adopted by the invention is as follows:
a method for rapidly generating a structure directory tree in a management platform based on BIM technology is characterized in that:
the method is realized by the following steps:
the method comprises the steps of adding LID coding attributes to components, separating BIM models from the coding attributes, performing tiling and lightweight processing on the models, and associating nodes with the components by using GUIDs (globally unique identifiers), so that the one-to-one correspondence relationship between each node and each component is created.
The method specifically comprises the following steps:
1) when a BIM model is generated, adding an LID coding attribute with a hierarchy concept to each member;
2) when entering a management platform, separating a three-dimensional model of the model from the coding attributes, and putting the GUID and the coding attributes of the component into a database;
3) carrying out tiling lightweight processing on the separated three-dimensional model entity in a management platform;
4) analyzing a database storing the coding attributes in a management platform, and generating tree nodes by using hierarchical coding;
5) the building blocks are bound to tree nodes using GUIDs.
In the step 1), the attribute value of the LID coding attribute is represented in a text mode.
In the step 3), the light weight processing means that only the outline structure is reserved and no parameterization information is contained.
The invention has the following advantages:
1. the method is simple and convenient, and mainly works by compiling the LID code with a layered structure and adding an attribute when generating the BIM model;
2. the structure directory management is easier to perform in the BIM management platform, the nodes and the components have one-to-one correspondence, the searching and the positioning and the attribute hanging of the component type are convenient, and the professional habit is better met;
3. the model and the attribute information are separated, the platform response speed is higher after the lightweight processing of the model, the attribute database is easier to expand and manage, and the efficiency is higher.
According to the invention, LID coding attributes are added to the components, the BIM model and the coding attributes are separated, the model is tiled and lightweight, and the GUID is utilized to associate the nodes with the components, so that the one-to-one correspondence between each node and the component is established.

Detailed Description
The present invention will be described in detail with reference to specific embodiments.
The invention relates to a method for quickly generating a structure directory tree in a management platform based on a BIM technology, which mainly comprises the following steps:
1) firstly, all directory nodes and components in a design unit are coded on the basis of a professional design unit, and the codes required by the nodes and the components are unique. As the design unit definition of the bridge: a relatively independent and complete engineering unit in a bridge specialty, such as a bridge, a culvert, etc., is divided into different design units when spanning different approximate calculation paragraphs.
Such as the XXX grand bridge, a complete directory structure tree of the bridge is built, which refers to a multi-level tree structure starting from the root directory of the design units and ending with the minimal building block unit. As shown in fig. 1.
2) When entering an engineering management platform, separating the three-dimensional body of the BIM model from the coding attribute, and putting the GUID and the coding attribute of the component into a database;
3) carrying out tiling lightweight processing on the separated three-dimensional model entity in a management platform, only retaining a contour structure and not containing any parametric information;
4) analyzing a database storing the coding attributes in a management platform, and generating tree nodes by using LID hierarchical coding;
5) the GUID is used to bind the building block with the tree node, and the whole flow chart is shown in fig. 2.
The LID coding method provided by the invention is simple in coding structure, accords with professional habits, is clear in corresponding node, is convenient to search for positioning and hanging the attributes of component types, is easier to read and identify by a computer, and is higher in efficiency.
The method can not only quickly position the position of the component in the directory tree, but also form a one-to-one mapping relation with the component, quickly find the component by using the node, quickly position the node by using the component, and realize the purpose of quickly generating the structural directory tree in the management platform based on the BIM technology.
