Ultraviolet broad-spectrum sterilization device based on intelligent perception

Abstract

The invention relates to an ultraviolet broad-spectrum sterilization device based on intelligent perception. The device comprises a detection module, a control module, a driving circuit, a transmitting light source and a transmitting antenna. The detection module, the control module, the drive circuit and the transmitting light source are connected in sequence. The transmitting antenna regulates and controls the light field distribution of the transmitting light source; the control module comprises a single chip microcomputer and a computer program which can be invoked and executed by the single chip microcomputer; and the computer program executes the following steps: acquiring detection information output by the detection module; carrying out intelligent analysis on the detection information to generate a numerical value adjustment instruction; generating a pulse width modulation control signal based on the numerical value adjustment instruction to act on the driving circuit; the transmitting light source adopts a multi-primary-color ultraviolet LED array and emits deep ultraviolet light with various wavelengths. Compared with the prior art, the ultraviolet broad-spectrum sterilization device has the advantages that the irradiation intensity and the irradiation duration of light emission can be intelligently controlled and the like.

Description

technical field [0001] The invention relates to the field of intelligent disinfection, in particular to an ultraviolet broad-spectrum sterilization device based on intelligent perception. Background technique [0002] In order to ensure public health safety and cut off family transmission and community transmission, the development of intelligent broad-spectrum disinfection epidemic prevention and control equipment is a major demand for national public health and people's life safety. At present, the traditional disinfection method is spray disinfection. This method has problems such as uneven liquid spraying, damage to the human respiratory mucosa, secondary pollution to the environment, and bulky equipment. UV disinfection is a fast, efficient and clean disinfection method. Studies have shown that using short-wave ultraviolet light with a wavelength of 254nm and an intensity of 303μW / cm2 for 30 seconds can kill more than 95% of the SARS virus. UVC ultraviolet robots have...

AI Technical Summary

Problems solved by technology

Mercury has serious pollution to the environment, and the radiation intensity of mercury lamps is generally fixed and is not suitable for working for a long time in a scene where people exist, and the safety is low

LED light sources emitting ultraviolet wavelengths on the market have a variety of wavelengths to choose from, but there is still a lack of in-depth research on the specific effects of UVC ultraviolet wavelengths on various viruses and bacteria

In addition, the luminous light of the ultraviolet lamp is too scattered, and the intensity of ultraviolet radiation in different directions within the disinfection range is not the same, the effective disinfection range is small, and there is a risk of missing disinfection
