Abstract: Based on the current situation of station equipment management in Chinese high-speed railway, a study of using 3D visualization technology and Internet of Things technology to realize the intelligent station equipment operation and maintenance management system for high-speed railway is made. The general framework of the system is given together with a description of its user structure and main functions. It is proposed to use Revit and 3DMAX for combined three-dimensional modeling, to use ArcGIS Pro for data creation and service publishing, and to make secondary development over ArcGIS by integrating multi-source data and using Internet of Things technology to collect and transmit data. By integrating technical records of high-speed railway station equipment, drawings, operation and maintenance data, monitoring data, etc. into the three-dimensional model to meet the needs of the users at different levels, the system will facilitate enhancing the level of informatization of high-speed railway station, improving the mode of station equipment operation and maintenance management, and reducing the cost in equipment operation and maintenance.
