Adaptive emergency evacuation navigation system for large commercial complexes

Abstract

The invention discloses an adaptive emergency evacuation navigation system and a method of a large-scale commercial complex, comprising fire monitoring, positioning navigation, path planning, evacuation indication and situation assessment. Firstly, the exact location of the fire is obtained according to the fire monitoring subsystem. Secondly, the positioning and navigation system uses the mobileterminal to obtain the position information of the personnel; Then, the path planning subsystem accurately calculates the effective evacuation path according to the hazard distribution map. Thirdly, the evacuation indication subsystem displays the effective evacuation path on the mobile terminal to conduct real-time navigation for the personnel of the handheld terminal; Finally, the situation assessment subsystem uses infrared images to obtain the hazard distribution map, and updates the building 's grid to ensure the effectiveness of the grid and improve the timely effectiveness of the planning path.

Description

technical field [0001] The invention relates to an adaptive emergency evacuation navigation system, which belongs to the field of fire safety of large buildings, in particular to an adaptive emergency evacuation navigation system for large complexes. Background technique [0002] With the continuous acceleration of urbanization in our country, commercial complexes have emerged as the times require. Commercial complexes often contain multiple functions such as commerce, catering, entertainment, etc., and have the characteristics of large population density and large construction area, especially some include underground buildings, resulting in a higher space closure. Crowds in large-scale commercial complexes tend to be highly concentrated and highly mobile, and often cannot fully understand the building structure. Once a sudden fire accident occurs, it is easy to cause panic among the crowd. At this time, if the evacuation cannot be carried out in a timely and effective man...

Problems solved by technology

However, the dynamic change trend of the fire and the dynamic distribution of personnel are still not considered, resulting in a certain delay in evacuation navigation, which cannot ensure timely evacuation of people to a safe area.
