Description
Technical field
The present invention relates to a kind of data interactive methods based on IFC, and using the Web-BIM engineering information collection of this method
At management system, belong to Information industry technical field.
Background technique
As construction project largely occurs, construction scale of projects and project complexity increasingly increase, there has been
A large amount of new large-scale tower building/construction equipments and arrangement and method for construction.In face of the challenge referred to without ready-made case, it is previous to undertake the construction of unit
The working method constructed under experience guidance, can not gradually adapt to what construction enterprises in industry made the transition to management type construction enterprises
Trend.And BIM(Building Information Modeling, architecture information model) technology many characteristics, answer it
With the requirement that can satisfy construction enterprises' transition and upgrade.Firmly " the 2011-2015 Construction Industry Information development guiding principle of the portion's of building establishment
Want " in clearly propose, to promote BIM cooperate etc. technical applications, popularize visualization, parametrization, threedimensional model design, to mention
High design level reduces construction investment, realizes and uses from the overall process of design, buying, construction, operation to operation is integrated.
Information technology has been that the industries such as manufacturing industry, electronics industry bring innovative variation, and Construction Industry Information journey
Degree is still in lower level.With the development of understanding about IT application, the design and construction field of construction project pass through BIM technology
It is innovated and is made the transition.BIM is different from single threedimensional model, the operation of simple software and previous effect picture demonstration, and
It is a kind of process and methodology.BIM is that the advanced managements such as total involvement, Whole Process Control and sustained improvement theory is general from being abstracted
Thought implements to the strong handgrip specifically produced；It is construction enterprises from being constructed with experience guiding construction to fine-grained management, lean
Effective supplementary means of transition.In face of large amount of complex, the new projects that first appear, it can refer to the feelings of reference in no successful case
Under condition, the integrality of BIM, authenticity, uniqueness, continuity and can virtual emulation the features such as, each participant of project can be allowed to mention
In preceding experience project building course and project build up after each important link, find the problem in advance and hidden danger, with reduce can
The risk and loss avoided improves project manager to the control force of quality, cost, safety and progress.Meanwhile BIM is also
The power of enterprise knowledge management, the important means of technological innovation and sustainable development.Therefore, the development of BIM has been each row
Industry, especially engineering construction field bring glad tidings.
But BIM also rests on certain specific stages in the application of architectural engineering industry, can not really realize towards building
The application of engineering life cycle management is built, and lacks effective connection between each stage.
There are many BIM class modeling software type, and there is a variety of data formats, and the data between each software systems are handed over
Mutually there is very big obstacle, leads to the information interchange and shared occlusion between each participant of project, form " information island "
Phenomenon can not carry out effective integrated management to project related data information.
The more existing engineering integrated management system based on BIM technology is all based on C/S framework, cannot achieve project
Foreign lands' synchronous interaction of management information, it is very high to the software systems requirement of client, and have very high maintenance cost.With this
Meanwhile traditional integrated management system also cannot achieve unified data format interaction and data visualization.
It is found through retrieval, the Chinese invention patent of patent No. CN201110023930.5 Authorization Notice No. CN102609417B
" Building Information Model data integration and switching engine device and method based on IFC standard " is proposed, supports multiple format
The conversion of BIM data, it can be achieved that BIM data integration towards building each stage lifetime or different application with exchange.However, this is specially
How benefit simultaneously not yet explicitly constructs IFC geometrical model converter and which kind of specific method for transformation to realize non-IFC file by
Conversion.
The Chinese invention patent application of application number CN201310042103.X application publication number CN103970919A proposes
" data processing method for the modeling of automatic architecture information ", although turning it is mentioned that carrying out format to multiple survey datas
It changes, but does not introduce and specifically how to convert.
The Chinese invention patent application of application number CN201310205695.2 application publication number CN103324475A proposes
" BIM model rendering optimization system and method based on IFC standard ", although it is mentioned that being passed through based on IFC entity library
The data mapping relations of definition realize that non-IFC format conversion is IFC reference format, but do not introduce and specifically how to convert.
