Description

technical field [0001] The invention relates to a flame detection alarm, in particular to an ultraviolet portable digital universal alarm module for flame detection. technical background [0002] The sensitive band of the ultraviolet UVC detector is in the blind area of ​​the solar atmosphere, so it is also called a solar blind detector. [0003] For natural flame detection, the temperature is low, and the fuel is organic matter. Usually, the spectral characteristics of the flame radiation spectral peak in the infrared region are used for detection with infrared detectors. However, when detecting weak black-body radiation targets (such as flames), although traditional visible-infrared detectors have higher photoelectric conversion efficiency for targets, the detection results are easily interfered by sunlight, and the detection background varies with seasons, weather, and detection time. , Geographical environment and other changes, it is not easy to select the response thr...
