Automatic alarm method and system based on Internet of Things

Abstract

The invention provides an automatic alarm method and system based on the Internet of Things, and the method comprises the steps: carrying out the analysis and processing of an internal environment image obtained through the visible light photographing of a target place, and obtaining the personnel distribution state information in the target place; analyzing and processing an infrared image obtained by infrared shooting of the target place to obtain fire source state information corresponding to the target place, and finally determining relative distance information between personnel in the target place and a fire source in combination with the personnel distribution state information and the fire source state information; and then according to the relative distance information and throughthe Internet of Things, instructing a corresponding position area to carry out fire alarm operation, so that fire alarm safety accidents in indoor public places can be timely and accurately monitored, and people gathered in the public places can be rapidly dispelled. Therefore, the intelligent and automatic degree of safety monitoring in public places is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of safety monitoring, in particular to an automatic alarm method and system based on the Internet of Things. Background technique [0002] At present, video surveillance equipment is installed in indoor public places, and the video surveillance equipment is used to capture images of different areas of indoor public places, and then analyze and process the captured images to determine whether there are potential safety hazards in indoor public places. The existing video monitoring equipment is to install corresponding camera equipment in different locations of indoor public places. Monitoring, which cannot accurately determine whether there is a fire hazard in indoor public places and the relative positional relationship between personnel and potential fire hazards, which is not conducive to timely and accurate monitoring of fire safety accidents in indoor public places and rapid detection Evacuate the peopl...

AI Technical Summary

Problems solved by technology

And the existing video monitoring equipment is to install corresponding camera equipment in the different positions of indoor public places, and this camera equipment can only carry out image shooting to the specific area of ​​indoor public place, and it can only monitor the personnel existence state of indoor public place. Monitoring, which cannot accurately determine whether there is a fire hazard in indoor public places and the relative positional relationship between personnel and potential fire hazards, which is not conducive to timely and accurate monitoring of fire safety accidents in indoor public places and rapid detection Relieving people gathered in indoor public places, thus greatly reducing the intelligence and automation of security monitoring in indoor public places
