Dynamic firefighting emergency evacuation indicating system for large-scale public building

Abstract

The invention discloses a dynamic firefighting emergency evacuation indication system for a large-scale public building. The dynamic firefighting emergency evacuation indication system comprises an evacuation indication setting subsystem, a firefighting monitoring and predicating subsystem, a dynamic evacuation indication adjusting subsystem and a crowd evacuation predicating subsystem. Firstly, evacuation indication distribution in the large-scale public building is set according to the evacuation indication setting subsystem; secondly, firefighting accidents happening in the large-scale public building are considered, multiple fire detectors are used for obtaining information such as the position and the intensity of a fire, and a computer model is used for predicating the development of the fire; thirdly, the development of the fire is used for dynamically adjusting evacuation indication to ensure that the evacuation indication points to a safe area; finally, a built cellular automaton evacuation model considering the evacuation indication function is adopted to predict crowd evacuation and feeds back a predication result to the dynamic evacuation indication adjusting subsystem. The evacuation indication is corrected again according to the crowd density, the evacuation time and the like, and the evacuation efficiency is improved.

Description

Technical field [0001] The invention is a dynamic emergency evacuation indication system that combines computer simulation technology, sensor technology, communication technology and other technologies, and belongs to the field of fire safety in large public buildings. Background technique [0002] As my country’s urbanization process continues to accelerate, large-scale public buildings continue to increase, such as office buildings, commercial buildings, science, education, cultural and health buildings, communication buildings, and transportation buildings, which have become very important in the cultural and economic life of the broad masses of people. a part of. The architectural structure of large public buildings has the characteristics of high space, large span, and large area, including some underground buildings. These places generally do not have doors and windows directly opened to the outside, and they are more closed. There are also places where goods are concentrate...

AI Technical Summary

Problems solved by technology

However, there are also some shortcomings. The existing intelligent evacuation systems often do not take into account the development of fire accidents, the evacuation of people in buildings, and related predictions. safe area

There is a lack of laws and regulations on intelligent evacuation indication systems in China, and there are few regulations on the layout of evacuation indications, and most of the research is based on algorithm optimization, and there are few practical applications
