Development And Application Of IFC-based Construction And Service Platform For Hydropower Project Information Model

With the continuous improvement of information technology,the amount of information obtained in the process of hydropower project management is increasing.However,the hydropower project management still has been information integration and poor interactivity currently,which is limited by the information technical level.With the deepening application of BIM technology in the field of water conservancy,technical support is provided to strengthen the information technology level of hydropower projects and improve the integration and sharing of various management elements.However,the utilization rate of BIM is still low at present.Therefore,based on IFC data,this paper expands the IFC of hydropower project,constructs the hydropower project information model,develops the hydropower project information model service platform,ensures the unified model standard and format,improves the utilization rate of BIM in hydropower project information management,and provides model services for hydropower project information management based on BIM,So as to better realize the data integration and business connection of project management.The research content mainly involves the following aspects:(1)Construction of hydropower project information model and analysis of service release method.First,expounds the key points of realizing BIM driven project information management,Secondly,explain the information model creation process from the aspects of hydropower project information model description,classification and coding,so as to ensure that the created information model meets the business requirements;Finally,the service release method is analyzed based on the hydropower project information model.(2)Analysis and storage of hydropower project information model based on IFC.Aiming at the response timeout of service caused by mass IFC data transmission,the slice breakpoint continuation technology is used to store the model file in the server.In view of the lack of analysis of the extended IFC model of hydropower project on the web,this paper implements the IFC analysis of hydropower project,and improves the problem of long analysis time caused by large amount of model information.Aiming at the problems of inconsistent model format in BIM driven project information management,such as information attribute loss,inconsistent binding identification between project information and model,etc.This paper defines the unified publishing model and realizes the transformation from IFC data on the web to the unified publishing model.Finally,combined with neo4 j,the IFC model of hydropower project is stored to improve the model retrieval efficiency.(3)Implementation of model service based on Three.js.Use the Three.js to study graphics rendering optimization methods to achieve real-time rendering of BIM models,and implement basic functions such as engineering information query,model segmentation,model annotation,model roaming,dynamic loading of model components,etc.Finally,design the model service interface to form a complete set of model service plug-ins.(4)Based on the above research,a hydropower project information model service platform based platform on IFC is built.Adopt the development mode of VUE2.6.14+Think PHP6.0 with hydropower project information model,IFC parsing and storage,model service plug-in,realize the construction of the overall architecture of the platform and the development of the main function pages,and verify the effectiveness of the service plug-in and platform through the application in the quality defect inspection system module.
