Abstract

The invention discloses a fire detection method based on image recognition and a temperature judgment algorithm, and relates to the technical field of fire fighting. The fire detector comprises a color image module, a near-infrared image module, an infrared thermal imaging module, a light supplementing lamp and an algorithm processing unit; the color image module is connected with the light supplementing lamp; the color image module, the near-infrared image module and the infrared thermal imaging module are connected with the algorithm processing unit; the algorithm processing unit adopts multiple judgment algorithms to judge the fire; the multiple judgment algorithms comprise a high-temperature abnormity judgment algorithm, a flame fire judgment algorithm and a smoke fire judgment algorithm. A user can carry out detection by adopting a mode that three detection modes of smoke detection, flame detection and high-temperature abnormity coexist, and the mode can also be customized. According to the invention, fire sources at different stages when a fire occurs can be detected.

Description

technical field [0001] The invention belongs to the technical field of fire protection, in particular to a fire detection method based on image recognition and temperature determination algorithms. Background technique [0002] At present, fire detectors based on image recognition technology, the core of which is to use 850nm-1000nm near-infrared infrared band imaging technology, the detection method and scheme are relatively single, and the false alarm rate is relatively high, especially in the outdoors. In coal, petrochemical, tobacco and alcohol It is impossible for manufacturing sites to alarm during the heat and smoke phase, especially when coal is in a natural and cloudy state. When a fire occurs in a petrochemical site, it will first heat up and then deflagrate. The existing technology is also unable to achieve very early detection and early warning. There are following disadvantages: [0003] 1) The false positive rate of a single detection band is high; [0004] 2...
