Embodiment

[0032] The concrete process that this embodiment realizes the building information model (BIM) management based on cloud computing technology is:

[0033] (1) BIM file analysis storage process based on cloud computing

[0034] Segmentation preprocessing is performed before BIM files are stored. Only after segmentation can parsing operations be performed in parallel. According to the segmentation strategy, a complete BIM file is divided into several fragments according to the principle of retaining the complete description information of its internal components. At the same time Establish the mapping relationship of the files, then upload the divided fragments to the Hadoop cluster for storage, and analyze the BIM in parallel, such as Figure 4 As shown, the specific implementation process is as follows:

[0035] 1. Data model design: establish a data model including relational data, non-relational data, and inverted index data. The relational data is stored in the database serv...

Abstract

The invention belongs to the field of cloud computing technology and relates to a building information model (BIM) management system and a method based on the cloud computing technology. By realizingdistributed analysis and storage of BIM data, the problem that the existing BIM management platform is unable to extract BIM data and carry out integrated application is solved. Moreover, the distributed parsing method is adopted to solve the problem of resolving memory overflow in a single host of the cluster when the platform handles the super-large BIM model. By providing user-oriented retrieval services, users can quickly and intuitively obtain data analysis results from multiple dimensions without learning complex query formulas to support the diversification of engineering project analysis needs.

Description

Technical field: [0001] The invention belongs to the technical field of cloud computing, and relates to a building information model (BIM) management system and method based on cloud computing technology. Background technique: [0002] With the continuous improvement of domestic building information modeling (BIM) technology, owners, developers, and design institutes have higher and higher data requirements, and personnel using this new technology will generate a large amount of data during the entire work cycle, which is A cloud data platform is needed to manage this information, ensure the uniqueness, accuracy, and timeliness of information read by everyone in the project, and provide them with fast and convenient project collaboration methods. CN201610577471.8 discloses a control system and method based on building information model, wherein the control system based on building information model includes a local database stored on a local server and a cloud database store...
