Real 3D Spatial Information Platform and Digital Twin Sichuan-Tibet Railway

Intelligence is an important direction of railway development in the world.Digital twin is an effective way to build the intelligent railway.The real 3D spatial information platform is the key foundation for accurate mapping and fusion of the whole life cycle of the twin railway in physical space and information space and the nerve center of“railway brain”.It is the key support for the information level and quality assurance of railway construction and management in the complex environment.Firstly,this paper introduces the development background of intelligent railway and the potential application of digital twin railway;secondly,it presents the overall framework and functional composition of the real 3D spatial information platform,and discusses the key technologies such as efficient organization and management of the multi-modal spatiotemporal big data,the adaptive aggregation and intelligent service of disaster information;Finally,for the urgent needs and main challenges of the construction of Sichuan-Tibet railway,it briefly summarizes and prospects the construction and application of the real 3D spatial information platform of digital twin Sichuan-Tibet railway.
