Description
Technical Field

Background
In recent years, under the promotion and support of national policies, the BIM technology in China is developed rapidly, and the three-dimensional digital design based on the BIM concept is accepted by more and more design houses and construction enterprises.

However, there are many problems in the utilization of BIM component resources in various enterprises, which are mainly reflected in the following aspects:
in engineering projects, designers construct a large number of BIM elements, but the elements are stored in the hands of individuals in a scattered manner, and a means for collecting and centrally managing the elements is absent, so that the multiplexing of the elements is not facilitated. On the other hand, in the prior art, a high-efficiency BIM element retrieval and calling tool is lacked, and the three-dimensional digital design efficiency is influenced. In the application of the BIM technology, information is important management content, and the information of various BIM elements is not uniformly managed by an effective means at present, so that the accuracy and the effectiveness of the information of the BIM elements cannot be ensured.
In a patent entitled BIM model resource management system and BIM model creation method (application No. CN201811541583.3), there is provided a BIM model resource management system and BIM model creation method, the system including: the BIM model resource library is used for storing and managing BIM model resources; the webpage end is used for uploading the BIM model resources to be uploaded to the BIM model resource library and managing and downloading the BIM model resources stored in the BIM model resource library; and the plug-in terminal based on the Revit platform is used for downloading and calling BIM model resources stored in the BIM model resource library to create a target BIM model. The above patent only solves the management and calling of the BIM component model, and does not solve the problem of attribute information management of the BIM component.
It will be appreciated that BIM components are the basis of BIM design, and that improvements in efficiency and quality of BIM design are greatly dependent on the completeness and level of management of the library of BIM components. Efficient BIM component management is indispensable for enterprises to implement the BIM technology, and therefore, a practical, effective and fully functional calling method for the BIM component model is urgently needed.

step 100: and establishing a mapping relation between the BIM element model and the attribute information corresponding to the BIM element model.
The BIM (building Information modeling) technology is used for providing a complete building engineering Information base consistent with actual conditions for a model by establishing a virtual building engineering three-dimensional model and utilizing a digitization technology. The information base not only contains geometrical information, professional attributes and state information describing building components, but also contains state information of non-component objects (such as space and motion behaviors). By means of the three-dimensional model containing the construction engineering information, the information integration degree of the construction engineering is greatly improved, and therefore a platform for engineering information exchange and sharing is provided for related interest parties of the construction engineering project.
BIM has the following characteristics: the method can be applied to not only design but also the whole life cycle of construction engineering projects; the design by BIM belongs to digital design; the BIM database is dynamically changed and is continuously updated, enriched and enriched in the application process; and a collaborative platform is provided for all parties participating in the project.
Step 200: and encoding the mapping relation.
Specifically, in order to manage the attribute information of the BIM component model, the attribute information of each type of component model is combed, and a coding rule is created. It should be noted that attribute information corresponding to a single BIM element model is not necessarily single, and may be a set of attribute information.
Step 300: and calling the BIM element model according to the coded mapping relation.
Preferably, the BIM component model and the corresponding attribute information may be called into the design end, and the attribute information may be loaded at the same time as the BIM component model is loaded. The calling tool can call element models based on Bentley related software, such as Open Building Designer and Open model, and can also call based on Revit software.
As can be seen from the above description, in the calling method of the BIM element model provided in the embodiment of the present invention, firstly, a mapping relationship between the BIM element model and attribute information corresponding to the BIM element model is established; then, coding the mapping relation; and finally, calling a BIM element model according to the coded mapping relation. The invention can intensively store and manage various BIMs of enterprises, provides a convenient element model warehousing and calling tool, and effectively improves the efficiency of BIM design; the attribute information of the BIM element and the model are put into a warehouse in a one-to-one correspondence mode, and the attribute information can be loaded to a design end along with the element model, so that the integrity and the accuracy of the attribute information of the BIM element are effectively guaranteed, and the unification of the model and the attribute is realized.
In one embodiment, referring to fig. 2, step 100 specifically includes:
step 101: and establishing a component model database, wherein the component model database is used for storing the BIM component model.
Specifically, a component model database is built from a plurality of BIM component models.
Step 102: establishing a component information database, wherein the component information database is used for storing attribute information;
specifically, a component information database is created from a plurality of attribute information. The BIM element models and the attribute information are in one-to-one correspondence, namely one BIM element model corresponds to one group of attribute information.

step 400: and coding the material corresponding to the BIM element model to generate a material code.
In one embodiment, referring to fig. 4, step 400 specifically includes:
step 401: classifying the plurality of BIM component models to generate a component model classification tree;
specifically, the BIM component model is subjected to classification statistics to form a component model classification tree (component catalog tree), for example: iron-making equipment, ore tank equipment and a movable unloading vehicle. The fixed attribute rule of each type of BIM element model exists under each type of BIM element model, and the material code of the BIM element model can be generated according to the attribute value of the BIM element model.
Step 402: and calling the BIM element model according to the material code, the element model classification tree and the coded mapping relation by using a Web Service method.
It will be appreciated that Web Service is a platform-independent, low-coupling, self-contained, programmable Web-based application that can be described, published, discovered, coordinated and configured using the open XML (a subset of the standard universal markup language) standard for developing distributed, interoperating applications. Which enables different applications running on different machines to exchange data or integrate with each other without the aid of additional, specialized third-party software or hardware. Applications implemented according to the Web Service specification may exchange data with each other regardless of the language, platform, or internal protocol used by them. Web Service is a self-describing, self-contained, available network module that can perform specific business functions. Web services are also easy to deploy because they are based on some conventional industry standards and some existing technologies, such as subset XML, HTTP under a standard generic markup language. Web Service reduces the cost of application interfaces. Web Service provides a generic mechanism for the integration of business processes throughout an enterprise and even across multiple organizations.
In one embodiment, referring to fig. 5, step 402 further comprises:
step 4021: and searching a BIM element model corresponding to the attribute information in the element model classification tree according to the material code and the attribute information by using the coded mapping relation.
