摘要:为了定量检测和净化汽车空气质量,并方便用户远程查看和控制,有针对性地设计了汽车空气质量智能检测净化系统和Android手机APP应用软件。车内外的PM2. 5检测系统和阵列气体传感器采集空气质量参数,Arduino处理器基于BP神经网络算法进行数据处理后自动调节空气质量,并通过HC-06蓝牙模块发送至Android手机APP,用户可在APP上查看空气质量并可手动调节。当车内PM2.5、CO、N〇2、HCHO浓度高于警戒值时,车内负离子空气净化器自动开启;车外浓度高于警戒值时,关闭外循环风扇。试验表明,与现有装置相比,系统不仅能同时检测包括PM2.5、C O在内的多种有毒有害气体及颗粒,还具备在APP上远程查看和净化车内空气的功能。

A b stra ct:In order to quantitatively detect and purify the autom otive air quality, and to rem otely view and con
trol it, a sm art system and an APP application softw are for Android mobile phone are designed. The air quality param eters are collected by PM2. 5 detection system and array gas sensors inside and outside the car. The Ar-duino is responsible for data processing based on BP neural netw ork algorithm and autom atically adjusting the air quality. The data are sent to the APP through HC-06 module, so the users can view the air quality on APP and adjust the param eters manually. When the inside values of PM2. 5, CO, N〇2and HCHO are higher than the alert value, the car negative ion generator will be opened automatically. When the outside value is higher than the alert value, the fan will be turned off. This system can not only detect a variety of toxic and harm ful gases and particles such as PM2. 5 and CO, but also rem otely view and purify the autom otive air quality by APP.

随着居住形式、工作方式和休闲需求的改变,人们在车内逗留时间越来越长,汽车几乎成为人们“可移动的家”。近几年来,我国部分区域空气质量明显下降,雾霾天气频繁出现,车外有毒有害气体通过车窗和空调进入车内,导致车内空气质量下降。车内空气质量状况会直接影响到乘客的健康和驾驶员的疲劳程度,近年来引发人们对车内外空气质量的关注,如何创

作者简介:袁圆(1993—),女,江苏盐城人,硕士,研究生,主要 研究方向为模式识别与智能自动化。造真正清洁、安全、舒适的车内空气环境已经成为亟待解决的问题[1]。
现有的车内空气质量检测仪主要安装在中高端车型上且检测气体种类单一,用户查询不方便,净化效果不明显。如比亚迪秦只安装了PM2. 5检测系统;雪佛和大空调内外
AQ S系统;丰田凯美瑞只在车内安装了负离子空气净化器和光触媒用来净化车内空气质量。
针对以上问题,研究设计了一种汽车空气质量智能检测净化系统。该系统可以同时检测PM2.5、CO、NO2、HCHO多种有毒有害气体与颗粒。Arduin。利用B P网络算法对传感器采集的数据处理后自动调节空调外循环和开启车内净化器。此外,还通过H C-06蓝
