【摘要】：近年來沙塵暴天氣發(fā)生的頻率雖有所降低,但土地沙化仍呈現(xiàn)不斷增加的趨勢。同時(shí),由于城市化進(jìn)程的不斷推進(jìn),土地荒漠化造成的沙塵和城市污染造成的霧霾等氣溶膠現(xiàn)象在很多方面相互影響,甚至形成惡性循環(huán)。如何高效、實(shí)時(shí)、精確地監(jiān)測沙塵環(huán)境中顆粒物濃度,成為目前環(huán)境大氣領(lǐng)域研究的一項(xiàng)重要課題。鑒于相關(guān)儀器的價(jià)格、性能等問題,本論文基于夏普生產(chǎn)的GP2Y1010AU0F傳感器開發(fā)了一款新型沙塵氣溶膠濃度測量系統(tǒng)。該儀器制作成本較低、測量精度良好,可用于土壤風(fēng)蝕、氣溶膠濃度測量等研究。首先,本文介紹了現(xiàn)有顆粒物濃度測量技術(shù)及其基本原理,并對其進(jìn)行比較,由此說明基于光散射原理的非接觸式顆粒濃度測量技術(shù)的諸多優(yōu)點(diǎn)；然后給出了基于光散射原理進(jìn)行氣溶膠濃度測量的物理原理,推導(dǎo)了球形粒子電磁散射問題的Mie散射基本解,進(jìn)而得到顆粒系統(tǒng)中群體散射光強(qiáng)度與個(gè)體散射光強(qiáng)度之間的關(guān)系；最后重點(diǎn)介紹了所設(shè)計(jì)測量系統(tǒng)的軟硬件結(jié)構(gòu)設(shè)計(jì),以及對系統(tǒng)的校正、驗(yàn)證和儀器相關(guān)實(shí)驗(yàn)結(jié)果的分析,并將其應(yīng)用在不同環(huán)境中顆粒物的測量,得到較好的結(jié)果,對后續(xù)系統(tǒng)改善方法及應(yīng)用領(lǐng)域進(jìn)行展望。本文的相關(guān)研究工作,對于后續(xù)在風(fēng)沙物理學(xué)中的風(fēng)蝕量的測量、沙塵及霧霾等氣溶膠顆粒濃度測量的研究具有一定的意義。
[Abstract]:Although the frequency of sandstorm weather has decreased in recent years, the land desertification is still showing an increasing trend. At the same time, due to the continuous progress of urbanization, Aerosol phenomena such as dust caused by land desertification and haze caused by urban pollution affect each other in many ways, and even form a vicious circle. It has become an important subject in the field of environment and atmosphere. In view of the price and performance of related instruments, Based on the GP2Y1010AU0F sensor produced by Sharp, a new dust aerosol concentration measurement system is developed in this paper. The instrument has the advantages of low cost and good measurement precision. It can be used in the study of soil wind erosion and aerosol concentration measurement. In this paper, the existing particle concentration measurement technology and its basic principle are introduced and compared, which shows the advantages of non-contact particle concentration measurement technology based on light scattering principle. Then the physical principle of aerosol concentration measurement based on the principle of light scattering is given, and the basic solution of Mie scattering of spherical particles is derived. Then the relationship between the mass scattered light intensity and the individual scattering light intensity in the particle system is obtained. Finally, the software and hardware structure design of the system is introduced, and the calibration, verification and analysis of the experimental results of the system are also given. It is applied to the measurement of particulate matter in different environments, and good results are obtained, and the improvement methods and application fields of the follow-up system are prospected. The relevant research work in this paper is concerned with the measurement of wind erosion in wind and sand physics. The study of aerosol particle concentration measurement, such as dust and haze, has some significance.
