| In the digital age,the use of advanced computer technology to the digital railway station construction,is the important measures to improve the efficiency of railway station construction and management.In order to meet the demand of wisdom plays an important role in the building of the city and realize the urban space utilization and accelerate the construction of indoor and outdoor,the integrated expression of up and down,and then realize the refinement of management,gradually become the urgent matter.Therefore,the establishment of efficient and practical hub railway station information system,not only can effectively achieve the construction of data management,at the same time to the station and passenger’s modern management is of great significance.According to the characteristics of railway stations,this thesis studies the BIM-GIS integration technology for the information construction of railway stations,and does the following research work:(1)This thesis analyzes the feasibility of integration of BIM and GIS in railway station information construction,and studies the conversion method from IFC model to City GML model in view of the differences in geometry,semantics and coordinates between IFC and City GML data standard in GIS field.(2)Based on the BIM modeling theory and the layout of railway stations,the modeling method and relevant standards of BIM modeling software Revit were analyzed,and the railway station simulation model was constructed according to the specific station renovation plan.(3)Through redevelopment of Revit software,the transformation and export of model geometry information and attribute information were realized.All import demand information database,through the development of GIS platform,to realize the integration of the model data and realization method of BIM-GIS integration technology research.(4)Conduct in-depth analysis on the information system integrated with BIM and GIS,and realize functions from data management of database,construction management of BIM to roaming and visualization of GIS.Taking Shijiazhuang North Railway Station as an example,it has been applied in the actual construction case.This thesis mainly studies the BIM-GIS model transformation and integration method.Based on the analysis and visualization of IFC standard files,the data format conversion method based on Revit platform and Arc GIS platform is proposed,and the BIM-GIS integrated information system for railway station information construction is constructed.This system can improve the efficiency of construction and operation and the comprehensive management level of railway station under smart city. |
