Research and Application of Key Technologies of BIM+GIS Virtual-reality Interaction for High-speed Railway Integration Test
2021
Integration test is an important security guarantee for high-speed railway operation. Aiming at the problem of chimney construction of more than 20 professional systems, which are scattered and lack of linkage, key technologies such as BIM+GIS multi-source heterogeneous data fusion, dynamic loading and rendering and lightweight model are put forward, and the virtual-reality mapping and interaction in physical railway and virtual twin railway scenes are realized based on "One Screen, One Picture" in BIM+GIS vehicle-mounted integration platform. The platform further explores the data value, and provides reference and guidance for lossless transmission of full life circle data of multi-professional and multi-participant railway based on BIM+GIS model, collaborative linkage, visual expression, immersive experience and intelligent decision-making, and further improves the intelligent management level of overall research and judgment of integration test, collaborative command and scientific decision-making and promotes the development of intelligent joint debugging.
