一种随身空气环境监测系统的设计

一种随身空气环境监测系统的设计(论文19000字)
摘要:近年来，随着我国工业、制造业的快速崛起，由此产生的空气污染问题日益严重，PM2.5、API指数越来越成为热门词汇，生活水平的提高使得人们对空气质量问题的关注也更加密切。随着由空气污染所引起的呼吸系统疾病日益增多，大众越来越认识到空气质量问题的严重性，认识到空气质量检测问题的必要性。然而，当前空气质量监测主要以固定站点的空气检测为主，虽然具有一定的代表性，但是远远不能满足个人对空气质量检测的需要，如家庭空气检测、办公室空气检测、随身空气检测。个人具有移动性，就要求能够随身携带的空气检测设备，能够随时检测周围较小空间内的空气污染指数以及温湿度等指数。本文目的在于开发一种基于单片机的空气质量检测设备，能够随身携带，实时检测个人周围空气环境的必要指数，包括PM2.5、温度湿度数值以及有害气体警示等，同时能够连接手机等终端，在手机等终端上实时显示空气指数。能够弥补城市空气检测的广泛性等缺点，对城市空气质量检测起到补充作用。

Design of a portable air environment monitoring system
Abstract:In recent years, with the rapid rise of industry and manufacturing industry in China, the problem of air pollution is becoming more and more serious. The PM2.5 and API index become more and more popular. The improvement of the living standard makes people pay more attention to the air quality problem. With the increasing number of respiratory diseases caused by air pollution, the public has become more and more aware of the seriousness of air quality problems and the necessity of air quality testing. However, the current air quality monitoring is mainly based on the air inspection of fixed sites. Although it has certain representation, it cannot meet the needs of individual air quality testing, such as home air inspection, office air inspection, and carry air inspection. With the mobility of the individual, the air testing equipment that can be carried around is required to detect the index of air pollution and temperature and humidity at any time in the smaller space around it. The purpose of this article is to develop a kind of air quality detection equipment based on single chip microcomputer, which can carry and detect the necessary index of the ambient air around the individual, including PM2.5, temperature and humidity value and harmful gas warning, and can also connect the terminal of mobile phone and so on, and display the air index in real time on the terminal of the mobile phone. It can make up for the shortcomings of universality of urban air detection, and play a supplementary role in the detection of urban air quality.
