Research Of Intelligent Medical Air Purification System Based On Internet Of Things

Air transmission is one of the main ways of virus transmission.Especially in medical facilities such as hospitals with dense patients,air quality monitoring and purification are particularly important.Among the existing air purification methods,disinfectants and ultraviolet rays are the most effective.They can inactivate most bacteria and viruses in the air,including novel coronavirus and influenza virus.However,personnel must leave the venue when using the above method for indoor air purification.In order to solve the above problems,this research designs and implements an intelligent medical air purification system based on the Internet of Things.The system includes a medical air purifier,a We Chat Mini Program,and an intelligent medical cloud platform.The main contents of this paper are as follows:Firstly,this paper introduces the research and design process of the medical air purifier based on STM32.The air purifier includes a main control chip,a data acquisition module,an air purification module,and a human-computer interaction module.STM32F103ZET6 microcomputer is selected as the main control chip.The data acquisition module uses a variety of sensors to collect air quality data in real-time.The air purification module uses a centrifugal fan,filters,activated carbon,an ultraviolet lamp,and a plasma generator to efficiently purify polluted air.The human-computer interaction module includes an infrared remote control module,a screen,and communication modules.The air purifier can be controlled by the screen,the remote controller,the We Chat Mini Program,and the cloud platform.Through the combination of ultraviolet and plasma,the air purifier can purify the air efficiently and remotely in real-time.Secondly,this paper introduces the research and design process of the We Chat Mini Program Fresh Air based on mpvue.The Mini Program includes the server and front-end pages.The server is built with EMQ X Enterprise,and front-end pages are developed with the mpvue framework.The Mini Program can remotely monitor air purifiers and indoor air quality in real-time.Finally,this paper introduces the research and design process of the intelligent medical cloud platform based on Vue.js.The cloud platform includes the server,database,back-end program,and front-end web pages.The server is built with EMQ X Enterprise,the database is built with My SQL,the back-end program is developed with the Express framework,and the front-end web pages are developed with the Vue.js framework.The cloud platform can remotely monitor and manage a large number of independent intelligent medical devices in real-time.
