Architecture Design and Key Technologies of Railway Digital Space Base
With the rapid development of intelligent construction in railway works,equipment,operation and other fields,the wide application of new surveying and mapping and engineering design technologies in the railway field is promoted,and massive amounts of new multi-dimensional and multi-modal railway spatio-temporal information data are formed.The model-data integrated platform in Intelligent HSR 2.0 also proposes a unified representation model library to realize the unified management and release of spatio-temporal information models in different stages including railway design,construction and operation.To this end,guided by the in-depth demand of intelligent railways for spatio-temporal information data and based on the existing railway geographic information platform of China State Railway Group Co.,Ltd.,this paper designs and proposes the overall architecture and technical composition of a new generation of high-precision railway spatio-temporal information service platform,builds a railway digital space base,makes breakthroughs in such key technologies as full-space data fusion,lightweight processing and service sharing and release.This study enables the intelligent application of railway spatio-temporal information,and also provides guidance and reference for the construction of representation model library in the intelligent HSR 2.0 model-data integrated platform.
