Description
Technical field
The present invention relates to a kind of data interactive method based on IFC, and the Web-BIM engineering information integrated management system of employing the method, belong to Information industry technical field.
Background technology
Along with construction project occur in a large number, construction scale of projects and project complexity increase day by day, there has been the newest large-scale tower building/construction equipment and arrangement and method for construction.In the face of without the challenge of ready-made case reference, undertaking the construction of the unit method of work of construction under experience instructs in the past, the trend that construction enterprises in industry make the transition the most gradually cannot be adapted to management type construction enterprises.And BIM(Building Information Modeling, architecture information model) many characteristics of technology so that it is application disclosure satisfy that the requirement of construction enterprises' transition and upgrade.Firmly " the 2011-2015 Construction Industry Information development outline " of the portion's of building establishment clearly proposes, the technology application such as BIM collaborative work to be advanced, universal visualization, parametrization, threedimensional model design, to improve design level, reduce construction investment, it is achieved from designing, purchase, build, go into operation to the integrated utilization of overall process run.
Information technology has been that the industry such as manufacturing industry, electronics industry brings innovative change, and Construction Industry Information degree is still in relatively low level.Along with the development of understanding about IT application, the design of construction project and construction field pass through BIM technology and innovate and make the transition.BIM is different from single threedimensional model, the operation of simple software and conventional design sketch and demonstrates, but a kind of process and methodology.BIM is the strong handgrip implementing to advanced management theories such as total involvement, Whole Process Control and sustained improvements from abstract conception specifically produce；Construction enterprises by with experience guiding construction to fine-grained management, effective supplementary means of lean construction transition.In the face of large amount of complex, the new projects that occur first, in the case of referring to without successful case use for reference, the integrity of BIM, verity, uniqueness, seriality and can the feature such as virtual emulation, the each participant of project can be allowed to experience in project building course in advance and project build up after each important step, pinpoint the problems in advance and hidden danger, to reduce evitable risk and loss, improve project manager's control power to quality, cost, safety and progress.Meanwhile, BIM is also enterprise knowledge management, the important means of technological innovation and the power of sustainable development.Therefore, the development of BIM has been that industry-by-industry, particularly engineering construction field bring glad tidings.
But, BIM also rests on some specific stage in the application of architectural engineering industry, it is impossible to real realization is towards the application of architectural engineering life cycle management, and lacks effective contact between each stage.
BIM class modeling software kind is a lot, and there is multiple data form, data interaction between each software system also exists the biggest obstacle, cause the communication for information between each participant of project and share obturation, define " information island " phenomenon, it is impossible to project related data information is carried out effective integrated management.
More existing engineering integrated management system based on BIM technology is all based on C/S framework, it is impossible to realize foreign lands' synchronous interaction of Project Management Information, requires the highest to the software system of client, and has the highest maintenance cost.Meanwhile, traditional integrated management system also cannot realize that unified data form is mutual and data visualization.
Find through retrieval, the Chinese invention patent of patent No. CN201110023930.5 Authorization Notice No. CN102609417B proposes " BIM data integration based on IFC standard and switching engine apparatus and method ", the BIM data supporting multiple format convert, and can realize towards building vital stage in each stage or the BIM data integration of different application and exchange.But, the most how this patent is built IFC geometric model converter and which kind of concrete method for transformation to be realized the conversion of non-IFC file by.
The Chinese invention patent application of application number CN201310042103.X application publication number CN103970919A proposes " data processing method modeled for automatic architecture information ", although it is mentioned that multiple survey data to be carried out form conversion, but not introducing and the most how to convert.
The Chinese invention patent application of application number CN201310205695.2 application publication number CN103324475A proposes " BIM model rendering based on IFC standard optimizes system and method ", although it is mentioned that based on the IFC entity storehouse, data mapping relations by definition, realizing non-IFC format conversion is IFC reference format, but does not introduce and the most how to convert.
