Monitoring and alarming device for intensity of ultraviolet disinfection lamp

Abstract

The invention relates to a monitoring and alarming device for the intensity of an ultraviolet disinfection lamp. The monitoring and alarming device comprises: a sensor module, which comprises an ultraviolet sensor and a distance measuring sensor; an ultraviolet disinfection lamp service time timer; a signal conversion module, which is connected with the sensor module and the ultraviolet disinfection lamp service time timer and used for collecting an ultraviolet intensity signal, a signal about the distance between the ultraviolet lamp and a target object and an ultraviolet irradiation time signal; a register, which is used for storing ultraviolet intensity, the distance between the ultraviolet lamp and the target object and a preset signal of ultraviolet irradiation time so as to obtain an alarming threshold for qualified disinfection; a comparator, which is used for monitoring a signal of the signal conversion module in real time and comparing the signal with the alarming threshold stored in the register so as to determine whether to send an alarming instruction; a timer, which is used for controlling the working state of the comparator; and an alarming module, which is used for comparing the alarming instruction sent by the comparator and sounding an alarming prompt accordingly.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and relates to a monitoring and alarm device, in particular to an ultraviolet disinfection lamp intensity monitoring and alarm device. Background technique [0002] The irradiance intensity of ultraviolet radiation lamps cannot be measured visually or felt. All are measured with a UV irradiator. However, the existing ultraviolet irradiator can only measure the radiation intensity, and cannot measure the distance between the ultraviolet lamp and the target object, cannot accurately measure the lighting time of the ultraviolet lamp tube, and cannot record relevant data. [0003] Hospital operating rooms, wards and other places often need to be disinfected with ultraviolet light, but it is not known whether the disinfection is qualified, and once the disinfection fails, it may cause immeasurable losses and consequences. Because this kind of disinfection needs to meet certain conditions ...

AI Technical Summary

Problems solved by technology

[0010] The present invention solves the problems that the current manual detection error is relatively large, the accurate measurement of the lighting time of the ultraviolet lamp tube and the distance between the ultraviolet lamp and the target object cannot be realized, and the physical damage of the operator is caused by ultraviolet radiation for too long; it provides An ultraviolet disinfection lamp intensity monitoring and alarm device
