Description

technical field [0001] The invention relates to the technical field of alarm devices, in particular to a visual image type fire detection and alarm device. Background technique [0002] With the increase of fire and electricity consumption in modern households, the frequency of household fires is getting higher and higher. Once a household fire occurs, it is easy to have untimely fighting, lack of fire extinguishing equipment, panic of the people present, and slow escape. Eventually lead to heavy loss of life and property, so the use of fire detection and alarm devices is becoming more and more extensive. Among them, the visual image fire detection and alarm devices can not only detect fires, but also perform real-time monitoring, making the monitoring more intuitive, but the existing When the image-based fire detection and alarm device broadcasts the fire image, a large amount of smoke and dust generated by the fire will cover the monitoring camera, which will cause the cam...

[0002] With the increase of fire and electricity consumption in modern households, the frequency of household fires is getting higher and higher. Once a household fire occurs, it is easy to have untimely fighting, lack of fire extinguishing equipment, panic of the people present, and slow escape. Eventually lead to heavy loss of life and property, so the use of fire detection and alarm devices is becoming more and more extensive. Among them, the visual image fire detection and alarm devices can not only detect fires, but also perform real-time monitoring, making the monitoring more intuitive, but the existing When the image-based fire detection and alarm device broadcasts the fire image, a large amount of smoke and dust generated by the fire will cover the monitoring camera, which will cause the camera to become blurred. After the camera becomes blurred, the broadcast image will not be clear enough, and the existing image Most permanent fire detection and alarm devices are directly fixed on high places, and the shooting angle cannot be adjusted, so it is impossible to conveniently shoot the source of the fire. Therefore, we propose a visual image type fire detection and alarm device
