The invention discloses a subway station fire safety egress guidance monitoring system on the basis of three-dimensional models. The subway station fire safety egress guidance monitoring system comprises an indoor BIM (building information modeling) three-dimensional simulation system, a field monitoring system, a monitoring terminal and a virtual display terminal. The virtual display terminal comprises a display module, a positioning module and an electronic compass module and is used for displaying three-dimensional navigation information and acquiring positioning information. The subway station fire safety egress guidance monitoring system has the advantages that the visualized three-dimensional models of spatial locations of the insides of subway stations are built by the three-dimensional simulation system, current locations of users and fire locations can be added into the visualized three-dimensional models according to the positioning information acquired by the virtual display terminal and monitoring information of the field monitoring system, and the three-dimensional navigation information can be formed according to egress exit guidance information transmitted by the monitoring terminal; a visualized navigation system with high reality sense can be provided for people, accordingly, quick and accurate safety egress guidance and monitoring can be provided for the users, and the subway station fire safety egress guidance monitoring system is favorable for improving the rescue and escape efficiency.
