Research On Visualization System Of Metro Mechanical And Electrical Construction Process Management Based On BIM

In recent years,with the rapid development of urban traffic construction in China,the management of Metro mechanical and electrical construction is facing more arduous challenges,and the management mode needs to be changed gradually.Nowadays,under the influence of network and hardware continuous updating and iteration,there are many obstacles in the traditional process management mode,which makes it more difficult to meet the construction requirements.In this context,this paper analyzes and studies the subway construction management,and proposes a visual management method of Metro motor construction technology based on BIM Technology.This research topic comes from actual project requirements,and the main research contents are as follows:This article uses WebGL’s engine framework Three.js Based on the half edge shrinkage algorithm of side length and curvature,the development process of model lightweight method and model file format conversion is described in detail.Based on the basic rendering of Metro electromechanical model,the roaming function is added.The bounding box algorithm and ray intersection algorithm are used to support the user’s click interaction on the model parts and edit the model online.On the basis of interaction function,the data-driven interaction is carried out between the picked model component objects and the component construction technology information in the database.Then,in order to meet the needs of process and construction information management,the subway electromechanical construction information management is designed and implemented,and then the integrated management of 3D model information can be realized.The B/S architecture adopted by the visualization system of Metro electromechanical construction technology is aimed at the application of the system in the actual enterprise and the relevant requirements of the technical level.The front-end and back-end separation strategy is used to build the system architecture.The MVC model is used to reduce the coupling of internal modules.In this paper,BIM Technology is effectively combined with the actual project requirements to meet the project requirements.Finally,the function and performance of the system are tested.The results show that the design and implementation of the subway mechanical and electrical construction technology management visualization system has a good application effect and development prospects.
