Burning and explosion accident sensing and risk predicting early-warning intelligent fire fighting helmet implementing method

Abstract

The invention relates to a burning and explosion accident sensing and risk predicting early-warning intelligent fire fighting helmet implementing method. A fire fighting helmet, a long-distance combustible gas detector, a thermal imaging camera module, a head-mounted near-eye display module, a positioning instrument, a data communication and transmission module, an embedded core board, an earphone, a base station, and a fire fighting command centre are involved. According to the burning and explosion accident sensing and risk predicting early-warning intelligent fire fighting helmet implementing method, the real-time position of a fireman in a building can be displayed for the fireman by combining a fireman positioning technology, a building information model and real scene thermal image information, and projecting and displaying information through the head-mounted near-eye display module, so that the environment burning and explosion dangerousness and risk thereof are predicted in real time. When the fireman enters an unknown environmental place, a potential fire disaster explosion accident risk can be effectively predicted quickly; quick sensing and information communication ofthe fireman to a fire disaster accident scene can be realized through an advanced video and thermal imaging technology and an indoor positioning and communication transmission technology, so that thefire fighting rescuing scientific level and the capacity of the fireman are improved.

Description

technical field [0001] The invention relates to a method for realizing explosion accident perception and risk prediction and early warning intelligent fire helmets, which is used for firefighter fire scene investigation, fire rescue site explosion accident risk prediction and early warning, and can provide support for firefighters' decision-making on fire-fighting and rescue site safety disposal. It can provide support for the on-site command center to have an in-depth understanding of the fire situation and conduct scientific decision-making command. Background technique [0002] When firefighters enter the building space to carry out fire fighting and rescue, they are often unclear about the information of the fire scene and have insufficient awareness of the risk of secondary fire and explosion accidents that may occur, which makes firefighters bear huge risks in the process of fire fighting and rescue. In the case of fire fighting and rescue in buildings or confined spac...

Problems solved by technology

At present, in terms of intelligent fire helmets, existing technologies and products often integrate thermal imaging, gas detection and alarm, communication intercom and other equipment, but the gas detection mostly uses inhalation gas detectors, mainly for the detection of gas at the position of firefighters. The detection and analysis of the concentration cannot realize the detection of the environment at the remote location of the firefighters, and it is impossible for the firefighters to quickly grasp the fire scene environment and the layout of building facilities and related information. Comprehensive intelligent analysis and judgment of on-site fire information, and visual display of fire site information and accident risk warning for firefighters, as well as firefighter rescue path navigation guidance and other functions
