Abstract: The Subway station has the characteristics of relatively closed space and relatively dense personnel. In order to avoid public safety accidents, the construction of the subway station safety equipment information family library can help strengthen the safe operation and supervision of the subway station. Based on building information modeling (BIM), the construction process of safety equipment information family library in subway station is established. Based on the definition and types of the family, Revit is used to build and load the standard component family to realize the establishment of the information family of the safety equipment in the subway station. Hefei city metro line 3 Qingyuan campus of anhui university station is selected as a case, using Microsoft Visual Studio C # to Revit secondary development, the security information library is constructed and applied, the 3D model of subway station is showed and the safety equipment information are extracted. The research results are helpful to realize the real-time and efficient management of safety equipment in subway stations, which is of great significance to the safe operation and supervision of subway stations.
