Intelligent information fusion image type fire hazard detector and detection information fusion method

Abstract

The invention discloses an intelligent information fusion image type fire hazard detector comprising an outer shield, an optical lens and imaging assembly, and a video image and information fusion assembly; the optical lens and imaging assembly is connected with the video image and information fusion assembly, and both are arranged in the outer shield; the optical lens and imaging assembly sends shot image information to the video image and information fusion assembly so as to carry out information fusion calculation, thereby outputting detection results. The invention also discloses a detection information fusion method of the image type fire hazard detector; the image type fire hazard detector has high sensitivity, can realize early detection of the fire hazard, is excellent in accuracy, very low in false alarm rate, good in environment adaptability, and can stably and reliably operate; the detection information fusion method of the fire hazard detector is based on the intelligent information fusion method, can maximumly reduce false alarms and alarm failure phenomenon, thereby effectively improving accuracy and reliability of the image type fire hazard detector.

Description

technical field [0001] The invention relates to an image type fire detector, in particular to an image type fire detector fused with intelligent information and a detection information fusion method thereof. Background technique [0002] The traditional smoke and temperature fire detection technology has some difficult defects: the detector must be installed near the fire point, otherwise it will not be able to effectively detect the occurrence of disasters; and the traditional fire detection technology is a contact-type passive method. It is difficult or impossible for the detection system to detect effectively in tall spaces (hangars, venues, large warehouses, etc.), outdoors, tunnels, etc. Therefore, fire detection in these places has always been a difficult problem for researchers and firefighters. [0003] Image fire detection technology and image-based fire detectors can effectively integrate the image features of smoke and flames and provide intuitive fire information...

Problems solved by technology

[0002] The traditional smoke and temperature fire detection technology has some difficult defects: the detector must be installed near the fire point, otherwise it will not be able to effectively detect the occurrence of disasters; and the traditional fire detection technology is a contact-type passive method. It is difficult or impossible for the detection system to detect effectively in tall spaces (hangars, venues, large warehouses, etc.), outdoors, tunnels, etc. Therefore, fire detection in these places is always a difficult problem for researchers and firefighters

In the actual situation of engineering applications, the image fire detectors currently using video image analysis technology as the main method are prone to false alarms under the interference of sunlight and artificial light sources; the environment of the protection area is complex, light interference, strong electromagnetic interference and dusty, Many detectors fail within a short period of time after being put into operation, making it impossible to reliably detect the protected area

[0006] (2) Insufficiency of fire imaging technology based on multi-spectral images

[0007] At present, the visible light or near-infrared image fire detectors widely used have the following disadvantages: the false alarm phenomenon of the detectors occurs from time to time; it brings hidden dangers to fire safety management

Therefore, there are also problems of false positives and low accuracy in multi-spectrum image fire detection.
