Subway station fire safety egress guidance monitoring system on basis of three-dimensional models

Abstract

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.

Description

technical field [0001] The invention relates to a navigation system, in particular to a monitoring system for fire safety evacuation guidance of a subway station based on a three-dimensional model. Background technique [0002] As an important facility of modern urban transportation, the subway has the characteristics of large passenger capacity, high speed and fast speed, and accurate time. Therefore, with the rapid development of my country's urban rail transit construction in recent years, the length of subway lines and passenger traffic have continued to increase. However, with the development of subway traffic, subway fire accidents also continue to occur. The subway has the characteristics of poor ventilation and lighting conditions, and complex internal environment. It is difficult to safely evacuate and rescue operations in case of fire. In a sudden fire accident, a large number of passengers flocked to narrow passages and stairs at the same time, and obstacles suc...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that in the case of a sudden fire in an existing subway station, it is difficult for fire fighters to identify their own position in the building, and it is impossible to quickly locate the specific location of the fire and the position of the trapped personnel. The scene is chaotic, which seriously affects the rapid escape of passengers. The purpose is to provide a 3D model-based monitoring system for fire safety evacuation guidance in subway stations, and provide people with a visual and realistic navigation system that can give users fast and accurate safe evacuation. Guidance and monitoring, which is conducive to improving the efficiency of rescue and escape
