Research On Visualization Of Engineering Information Management Of Railway Station Based On BIM

With the rapid development of railway transportation,the demand for railway transportation capacity has increased year by year,and the construction of railway stations has entered a period of rapid development.Railway station engineering is deeply affected by multi-professional coordination,multi-department management,and multi-link decision-making,which increases the complexity of railway station engineering data.Therefore,problems such as lack of data,information faults,and management disconnection are particularly prominent in railway station engineering.Research on digital information management is inadequate,which brings great challenges to engineering data management^[1].Relying on the advantages of BIM（Building Information Modeling）in visualization,standardization,informatization,parameterization,etc.,integrating BIM into railway station engineering data management,and comprehensively using AR（Augmented Reality,augmented reality technology）,VR（Virtual Reality,virtual reality technology）and other technologies to form an efficient,interactive and systematic data management system.The management of railway station engineering data based on BIM technology is an innovative management concept.It is different from the traditional data management mode.This management mode combines with modern management technology and information technology.It takes data management as the core and solves the problem of railway station.Pain points of information islands in engineering data management throughout the life cycle.Visualize and interact engineering data with a three-dimensional model as a carrier,which can more conveniently and intuitively find relevant information through the model,provide engineering data management guidance for railway engineering projects,provide new models and ideas for project management,and scientifically build railway stations.Engineering data management system has a promoting role^[2].Based on the above objectives,this paper takes a railway station of the Beijing-Shanghai high-speed railway as the research object,and systematically manages the railway station data visualization based on BIM technology.Technology,system integration of railway station data and models for in-depth research.main tasks as follows:（1）Based on the connotation of railway construction data management based on BIM,relying on the advantages of BIM in visualization and parameterization,BIM is introduced into railway station engineering data management,and geometric modeling technology and3D scanning of railway engineering information model Relevant modeling technologies such as molding technology have been specifically studied,and the development history,technical principles,and working steps of VR and AR technologies have been introduced.Finally,the technology integration between railway engineering information models and AR and VR is studied for subsequent development.BIM-related technology fusion provides technical support.（2）Research on the development of the railway station engineering information database,sort out the data,and systematically process the data according to the file format of the data and the area of the station corresponding to the data.Investigate a variety of different standards such as the data archiving standard,the International Framework for Dictionaries（IFD）standard,summarize the data archiving standards suitable for railway stations,and finally build the railway station engineering database to complete the document database and attributes of the data.Database construction,and complete cloud database based on cloud platform construction.Provide data support for building a railway engineering data management system with information management,multi-dimensional display,and multi-technology integration.（3）Research on the visualization of engineering data management with multi-technology fusion.The advantages of the combination of BIM and VR technology and BIM and AR technology are studied.The integration of VR,AR and BIM technology is carried out for the comprehensive research and application of model informationization.Interactive management of railway engineering data with BIM+AR/VR.Finally,the application research of railway station engineering data management based on BIM+VR and BIM+AR technologies is carried out.（4）The system integration of railway station data and models is studied,and the family libraries and three-dimensional models of railway stations and stations are established,and the research on model optimization technology is carried out.Based on the IS3 platform for secondary development,complete a model information management system with BIM5D visual display,standardized information query,and diversified data retrieval.In this system,background related data is retrieved through the BIM model and communicated with other modules to achieve multiple ways to associate engineering data with the model.This article provides practical solutions for research on railway station engineering data management,improves the efficiency of data management in the whole life cycle of such projects,and promotes the informatization and digital development of railway station engineering^[3].
