Problems solved by technology

[0003] In order to avoid the interference of sunlight, the commonly used UV detectors on the market need to add filters to eliminate the influence of sunlight to reduce the false alarm rate. These accessories are generally bulky, fragile and expensive, which increases the complexity and manufacturing of the detector. The cost also greatly reduces the scope of application of the detector

Abstract

The present invention relates to a heterojunction thin film-based remote electrical fire hazard monitoring system and a preparation method thereof. The heterojunction thin film-based remote electrical fire hazard monitoring system is composed of an europium oxide / gallium oxide heterojunction thin film chip, an ultraviolet photoelectric detection peripheral circuit, an LED indicating lamp and a network communication module. The europium oxide / gallium oxide heterojunction thin film chip comprises an europium oxide thin film, a gallium oxide thin film, a Ti / Au thin film electrode and an n-type Si substrate, the thickness of the europium oxide thin film is 100-150 nm, and the thickness of the gallium oxide thin film is 200-250 nm. The europium oxide thin film and the gallium oxide thin film forms an europium oxide / gallium oxide heterojunction, and the n-type Si substrate is used as the substrate of the gallium oxide thin film. The heterojunction thin film-based remote electrical fire hazard monitoring system of the present invention can send the fire hazard alarm information to a computer or a mobile phone terminal, thereby realizing the remote monitoring and alarm. The europium oxide / gallium oxide heterojunction thin film chip is stable in performance, high in responsivity and sensitivity, can be applied to the remote electrical fire hazard alarm and the high voltage line corona remote monitoring, and has the wide application prospect.

Description

technical field [0001] The invention relates to an electrical fire monitoring system, in particular to a remote electrical fire monitoring system based on a heterojunction thin film and a manufacturing method thereof. technical background [0002] At present, there are more and more electrical fires caused by the aging and discharge of electrical equipment, causing great property losses to people. Therefore, it is urgently needed in the current security field to research and develop a remote fire monitoring and alarm system that can accurately and effectively detect the spark signal, find the source of the fire at the first time, and prevent it from "burning". [0003] In order to avoid the interference of sunlight, the commonly used UV detectors on the market need to add filters to eliminate the influence of sunlight to reduce the false alarm rate. These accessories are generally bulky, fragile and expensive, which increases the complexity and manufacturing of the detector....
