Real-time situation awareness-based evacuation adaptive selection method, system and terminal

Abstract

The invention provides a real-time situation awareness-based evacuation adaptive selection method, a system and a terminal. The method comprises the following steps that: step S1, path segments are classified according to road types, and the passage time of a people group to be evacuated is predicted according to the environmental factors of each path segment and the factors of the people to be evacuated; step S2, an evacuation route enabling the least total usage time is adopted as an optimal evacuation route according to the passage time realized by each path segment; and S3, the people to be evacuated are evacuated and escape according to the optimal evacuation route, and the method returns to S1 if the passage quality of a certain path segment attenuates quickly or congestion delay increases during an evacuation process. With the evacuation adaptive selection method of the invention adopted, the route enabling the least total usage time is obtained according to two environmental factors, namely temperature and oxygen content in the channel, and the factor of the people to be evacuated; an environment in the channel is monitored in real time during an evacuation process, so thatthe route can be adjusted in time; and therefore, the safety of the people to be evacuated can be ensured, and evacuation time can be significantly reduced.

Description

Technical field [0001] The invention relates to the technical field of building safety, in particular to an evacuation adaptive selection method, system and terminal based on real-time situational awareness. Background technique [0002] With the rapid development of economy and society and the deepening of urbanization, various uncontrollable disasters have increased significantly, especially complex structures of high-rise buildings, tourist attractions, parks and other places with high density of people. Once a catastrophic emergency occurs , Such as fires, earthquakes, terrorist attacks, etc., the crowd will be greatly threatened. Through statistical analysis of emergencies in places where people gather at home and abroad, all accidents that cause heavy casualties are closely related to the lack of reliable safe evacuation facilities or management plans, and the inability of people to evacuate to safe refuge areas in time. The time of the evacuation route is the decisive fac...
