Description
Technical field
The present invention relates to a kind of engineering information systems based on BIM, MR in conjunction with 3DP technology.
Background technique
BIM, that is, Building Information Modeling, means Building Information Model, contains architectural engineering item
Mesh from planning, prospecting, conceptual design, detailed design, analysis, go out figure, it is prefabricated, construction, construction logistics, operation maintenance and dismounting or
All information of the Life cycle of person's renovation, these information include geographical location, engineering background, design information, construction letter
The information such as breath, material source, operation maintenance data and dismounting renovation.
MR, that is, Mixed Reality, means mixed reality, is an emerging technology, it be by hologram, will be real
Environment is mutually mixed with virtual environment.The new visible environment for merging reality and virtual world and generating, in new visualization
Physics and information data coexist in environment, and real-time interactive.
3DP, that is, 3D Printing, means 3D printing, is a kind of technology of Quick-forming, it using digital model file as
Printing basis, the material that can be bonded using powdery metal or plastic etc., using the method successively accumulated come the construction bodily form
Shape, he is identical as common printing technique principle.
SQL Server database is a kind of system R that U.S.'s Microsoft Corporation is released, and is one
It is expansible, high performance, designed data base management system is calculated for distributed client/server, realize with
The combination of WindowsNT provides the enterprise-level information management system scheme based on affairs.
