Abstract: According to the production characteristics of railway marshalling station, this paper designed an intelligent platform of railway digital marshalling station based on the six-dimensional model of digital twin. The platform was with the functions of dynamic tangible prompt for transportation production information of marshalling station, real-time intelligent research and judgment and early warning of transportation safety risk, all-round intelligent analysis and early warning of professional management, intelligent statistical analysis and problem research and judgment of construction and maintenance, and high-precision positioning of outdoor operators and intelligent alarm of behavior track. The trial shows that the platform can effectively improve the risk safety management level and safety management efficiency of railway marshalling station.
