Prospect of Key Technologies of Intelligent HSR 2.0 Empowered by Model-Data Integration Platform
Relying on the major projects of Beijing-Zhangjiakou HSR,China's railway industry has integrated and applied several digital intelligence technologies to form a complete set of intelligent HSR 1.0 technology,which has been popularized and applied to several new lines.With the continuous deepening of intelligent applications in construction,equipment,operation and other fields,there is an increasingly urgent need for integrated sharing and analysis of models and data.This paper analyzes the connotation and key points of model-data integration and puts forward the overall architecture of model-data integration platform composed of model-data convergence layer,model-data storage layer,model-data management layer,model-data calculation layer,model-data aggregation layer,etc.,and looks forward to leading key technologies and several innovative key technologies such as intelligent engineering survey and generative design,all-discipline intelligent construction,digital twin of railway engineering,CR450 intelligent EMU,new generation of dedicated mobile communication for railway(5G-R),operation safety protection based on multi-source information perception,transmission and fusion analysis,displacement-based full-travel intelligent service(MaaS+),intelligent comprehensive dispatching of regional railway network,wheel-rail integrated intelligent maintenance of EMU,etc.It can provide guidance and reference for digital railway construction and intelligent HSR 2.0 scientific & technological breakthroughs.
