Study On The Visualization Of Emergency Information Of Urban Subway Stations With BIM Method

As an important infrastructure of the city,underground rail transit,which is convenient for urban residents to travel efficiently,also has a large passenger capacity,which can effectively relieve the pressure of urban population and traffic congestion.However,the subway station is densely populated and the space is relatively closed,which adds many difficulties to its own safe operation and management.Building information model(Building Information Modeling,BIM)has unique advantages in engineering data information exchange management,construction control and so on,It is suitable for all stages of urban subway station project,the application of it in the urban subway station projects is helpful to realize the overall macro decision and local micro management of the whole life cycle of the project and to improve the efficiency of the project construction significantly.The urban subway station has been taken as the research object,takes Autodesk Revit as the core modeling software and C # as the programming language,carry on the research on modeling and security information visualization of the subway station which is based on BIM,the concrete content is as follows:(1)Based on the theory,this paper introduces the main features of urban rail transit projects and the concepts of BIM,BIM owns the features of three-dimensional visibility,coordination,simulation and information interaction,it is suitable for the rail transit projects and can help improve the operational management efficiency of subway stations.(2)This paper briefly describes the main application of BIM technology in the whole life cycle of urban subway station.(3)Anhui University Qingyuan Station of Hefei Rail Transit Line 3 has been taken as an example,accoeding to the specific situation,a perfect BIM model is built for subway stations in order to build a foundation for safety information visualization of subway stations,this paper enriches the family library of urban subway stations by building new standard component families,loading and modifying the standard component families.(4)Based on the principles of real-time,positionability and high efficiency,designing,developing and realizing the safety information visualization plug-in for urban subway stations,the results show that the visual plug-in created in this paper can collect and analyze the information collected by the detector in real time,transmit and view the pictures collected by the monitoring equipment in realtime,and quickly locate the over-standard detector and abnormal monitoring picture position,and transmit the early warning information to the relevant personnel in time,which will help to realize the real-time and efficient management of the subway station equipment.
