Early fire monitoring and early warning method and device

Abstract

The invention provides an early fire monitoring and early warning method and device, and the method comprises the steps: 1, collecting the image information of an indoor environment through a camera disposed indoors so as to carry out the judgment of a fire; monitoring the indoor environment parameter information capable of representing the fire disaster in real time through a sensor installed in an indoor monitoring area where the fire breaks out easily; 2, processing the indoor environment image information and the environment parameter information to respectively obtain a flame detection posterior probability and a fire hazard posterior probability; and 3, inputting the flame detection posterior probability and the fire hazard posterior probability as basic reliability functions of different evidence sources into a DS evidence theory for decision fusion so as to obtain a fire hazard prediction result. According to the invention, a multi-characteristic quantity data fusion method is utilized, the fire prediction model is created, the accuracy and the stability are improved, early warning of the fire can be achieved, the fire disaster can be timely and effectively monitored, and the possibility of fire occurrence is reduced to the minimum.

Description

technical field [0001] The invention relates to the technical field of fire monitoring and early warning, in particular to an early fire monitoring and early warning device and an early warning method. Background technique [0002] The current catastrophic fire outbreaks seriously threaten the safety of people's lives and property. With the continuous increase of urban high-rise and underground buildings, the use of flammable and flammable building decoration materials, and the aging of various electrical equipment and cables directly lead to the increase of fire hazards, and the number of fires and casualties caused by each year are also increasing. tend. Therefore, to be able to quickly and accurately fire early warning has become an important topic of environmental safety monitoring. Traditional fire detectors mostly use a single fire characteristic parameter such as smoke, gas, temperature, and flame as the basis for fire judgment. A single fire detector only uses a si...

Problems solved by technology

[0003] The purpose of the present invention is to solve the defects in the above-mentioned prior art, and provide an early fire monitoring and early warning device and early warning method. Considering the shortcomings of the current fire detection method and the imperfect function of the device, the present invention develops embedded hardware , machine learning and reasoning decision-making technology are applied to early fire warning, and a fire prediction model is established. The acquisition device stores the collected environmental characteristic parameters in real-time in the historical data storage module, and inputs them into the model for fire prediction, and displays them on the host computer interface. Display the alarm judgment result
