【摘要】：我國是正處于高速發(fā)展中的大國,在工業(yè)化規(guī)模不斷擴(kuò)大的同時(shí),環(huán)境污染問題也日益嚴(yán)重。近幾年來,隨著人們環(huán)保意識(shí)的提高,人們?cè)絹碓疥P(guān)注室內(nèi)空氣污染問題對(duì)人身體健康的影響。在我國,室內(nèi)空氣污染主要是由于建筑材料的低標(biāo)準(zhǔn)、空調(diào)的大量普及和可吸入性顆粒引起的,其中可吸入性顆粒主要指的是PM2.5,有研究表明,PM2.5所引起的霧霾天氣對(duì)人體健康危害程度甚于沙塵暴。針對(duì)目前市場(chǎng)上的空氣質(zhì)量監(jiān)測(cè)產(chǎn)品價(jià)格昂貴,體積大,便攜性差,測(cè)定周期長(zhǎng),有時(shí)需要專業(yè)人員進(jìn)行操作而無法普及的情況,本文設(shè)計(jì)了一款具有較高性價(jià)比的室內(nèi)空氣質(zhì)量監(jiān)測(cè)系統(tǒng),目的是為了提高人們的生活質(zhì)量,使人們能夠?qū)崟r(shí)掌握室內(nèi)空氣質(zhì)量情況。本文開展并完成以下工作:1、首先,根據(jù)市場(chǎng)需求,提出空氣質(zhì)量監(jiān)測(cè)系統(tǒng)的整體設(shè)計(jì)方案;2、其次,根據(jù)提出的整體設(shè)計(jì)方案,完成系統(tǒng)硬件的設(shè)計(jì),例如分別進(jìn)行了溫濕度傳感器的選型和傳感器電路設(shè)計(jì),CPU的選型、MP3電路設(shè)計(jì)以及其他外圍電路設(shè)計(jì)等;3、再次,在硬件設(shè)計(jì)的基礎(chǔ)上完成各模塊的軟件開發(fā)和實(shí)現(xiàn),主要是利用嵌入式實(shí)時(shí)操作系統(tǒng)μC/OS-II以及嵌入式圖形系統(tǒng)μC/GUI來實(shí)現(xiàn)系統(tǒng)各模塊的驅(qū)動(dòng)。4、最后,對(duì)系統(tǒng)進(jìn)行整體調(diào)試,測(cè)試系統(tǒng)的正常性,根據(jù)采集得到的數(shù)據(jù)計(jì)算出各傳感器的測(cè)量精度,再對(duì)數(shù)據(jù)進(jìn)行基于BP神經(jīng)網(wǎng)絡(luò)算法和灰色關(guān)聯(lián)度分析的兩級(jí)數(shù)據(jù)融合,得出室內(nèi)環(huán)境質(zhì)量報(bào)告,總結(jié)所做工作,對(duì)系統(tǒng)的不足提出改進(jìn)。
[Abstract]:China is a large country in rapid development. With the expansion of industrialization, environmental pollution is becoming more and more serious. In recent years, with the improvement of environmental awareness, people pay more and more attention to the impact of indoor air pollution on human health. In China, indoor air pollution is mainly caused by the low standard of building materials, the popularization of air conditioning and the inhalation of particles. The haze weather caused by PM2.5 is more harmful to human health than sandstorm. In view of the fact that the current air quality monitoring products on the market are expensive, large in size, low in portability, long in measuring cycles and sometimes requiring professional operations that cannot be popularized, An indoor air quality monitoring system with high performance-price ratio is designed in this paper. The purpose of this system is to improve people's quality of life and enable people to grasp the indoor air quality in real time. The following works are carried out and completed in this paper: 1. Firstly, according to the market demand, the whole design scheme of air quality monitoring system is put forward; Secondly, according to the overall design scheme, the hardware design of the system is completed, such as temperature and humidity sensor selection and sensor circuit design, CPU selection, MP3 circuit design and other peripheral circuit design. Third, on the basis of hardware design, the software development and implementation of each module is completed, mainly using embedded real-time operating system 渭 C/OS-II and embedded graphics system 渭 C/GUI to realize the driver of each module of the system. The system is debugged as a whole, the normality of the system is tested, the measurement accuracy of each sensor is calculated according to the collected data, and the data is fused by two levels based on BP neural network algorithm and grey correlation analysis. Get the indoor environmental quality report, summarize the work done, and improve the system.
