Fire evacuation system and method based on computer vision and heuristic search algorithm

Abstract

The invention discloses an intelligent fire evacuation system and method based on computer vision and heuristic search algorithms. The system comprises a monitoring subsystem, a computer control subsystem, a single-chip microcomputer control circuit and a splicing type escape indication board; the monitoring subsystem is composed of a camera set, a smoke alarm set and a manual fire alarm; the computer control subsystem is composed of a building channel layout database, a computer vision algorithm module and a heuristic path search algorithm module; the single-chip microcomputer control circuitis composed of a single-chip microcomputer, a latch, a decoder and an alarm whistle; a plurality of escape indicating lamps are controlled at the same time under the indication of the computer control subsystem, and an alarm device is immediately controlled to give an alarm when a fire is discovered; and the splicing type escape indication board is composed of a splicing type external structure,a decoder, a logic chip and a light emitting diode. The technical scheme of evacuating crowded people by intelligently planning a secondary short escape route is realized.

Description

technical field [0001] The invention relates to the technical field of computer intelligent application, in particular to an intelligent fire evacuation system and an evacuation method based on computer vision technology and a heuristic search algorithm. Background technique [0002] In recent years, fires in buildings have occurred frequently, and building fires have even become one of the major disasters that threaten urban public safety. However, due to the narrow passages and compact rooms in general buildings, once a fire occurs, it will spread rapidly, making it difficult to fight and evacuate. However, due to the chaos of escape, the timing of escape is delayed, and people are often forced to break windows and jump from buildings, and even escape stampedes occur. These problems have brought huge hidden danger to the safety of people's life and property. [0003] The existing fire alarm system can only serve as an alarm when a real fire event occurs, but cannot truly...

However, due to the narrow passages and compact rooms in general buildings, once a fire occurs, it will spread rapidly, making it difficult to fight and evacuate.

However, due to the chaos of escape, the timing of escape is delayed, and people are often forced to break windows and jump from buildings, and even escape stampedes occur.

These problems have brought huge hidden dangers to people's life and property safety.

[0003] The existing fire alarm system can only serve as an alarm when a real fire event occurs, and cannot truly evacuate the crowd. Simple safety exit signs can play little role in emergency situations
