Problems solved by technology

[0003] At present, there are also applications of ultraviolet detectors on the market, but the detected spectrum covers all ultraviolet light bands below 380nm, which is easily interfered by sunlight and has a high false alarm rate. However, solar-blind ultraviolet detectors can detect sparks in sparks. The sun-blind band ultraviolet light that exists, but does not exist in sunlight, greatly reduces the false alarm rate

Description

technical field [0001] The invention relates to an electric spark detection and alarm system, in particular to an intelligent electric spark detection and alarm system based on a PN junction chip and a preparation method thereof. technical background [0002] Most of the fire detectors on the market are based on the mechanism of temperature sensing, smoke particles, and infrared light detection. These devices often work when a fire has already occurred with open flames or smoke, and the alarm at this time is relatively late. According to statistics, 80% of warehouse fires are caused by electric sparks caused by aging discharge of electrical equipment. This process will emit deep ultraviolet light (200-280nm) in the sun-blind band, which can be detected. Therefore, research and development of an intelligent fire alarm that can accurately and effectively detect electric spark signals and prevent them from "burning" is urgently needed in the current security field. [0003] A...
