【摘要】：海洋中的硝酸鹽濃度是海洋環(huán)境檢測時的重要參數,獲取海水中硝酸鹽的時空分布數據對海洋生態(tài)系統(tǒng)研究、海洋水質評估等具有非常重要的意義。國內的海洋硝酸鹽檢測主要依靠人工采樣到實驗室進行實驗,達不到原位檢測的需求；而購買國外的原位檢測儀器需要花費大量財力,且儀器維護不方便。因此研制出具有我國自主知識產權的高精度、低功耗、高穩(wěn)定性的原位硝酸鹽檢測儀器具有重要的意義。 本論文在分析了國內外先進的硝酸鹽檢測儀器技術發(fā)展現狀的基礎上,綜合運用光學、物理學、機械學、電子學以及計算機科學技術等各個學科知識,基于紫外分光光度法檢測方法進行原位檢測儀器的設計,包括機械光路、電子電路、算法以及軟件界面,自主研制出基于紫外分光光度法的精度高、功耗低、穩(wěn)定性好的硝酸鹽原位檢測裝置。 實驗結果表明：海洋硝酸鹽原位檢測儀器的檢測精度可達0.5μmol/1；線性度高達0.9988,檢測線性范圍為1-320μmol/1；穩(wěn)定性好,均方差為0.009551。該系統(tǒng)具有很好的性能,達到同類硝酸鹽原位檢測儀的國際水平。 本論文一共六章： 第一章首先闡述了論文的研究背景以及意義,介紹了硝酸鹽的常用檢測方法,以及運用于水體的硝酸鹽檢測方法,最后提出了一套基于紫外分光光度法的海洋硝酸鹽原位檢測方案。 第二章介紹了紫外分光光度法進行物質的光譜分析的原理,以及常見海洋物質的紫外光譜。 第三章介紹了海洋硝酸鹽原位檢測系統(tǒng)的設計,包括系統(tǒng)總設計、機械設計、硬件設計等。 第四章介紹了海洋硝酸鹽原位檢測系統(tǒng)軟件的設計,包括軟件需求說明、系統(tǒng)軟件設計、界面設計、通訊設計、數據的算法設計等。 第五章介紹了實驗設計部分,以及實驗結果分析等。 第六章是總結與展望。
[Abstract]:The concentration of nitrate in the ocean is an important parameter in the detection of marine environment. It is very important to obtain the temporal and spatial distribution data of nitrate in sea water for the study of marine ecosystem and the evaluation of marine water quality. In China, the detection of marine nitrate mainly depends on manual sampling to the laboratory for experiments, which can not meet the demand of in-situ detection, but it takes a lot of money to purchase foreign in-situ detection instruments, and the maintenance of the instruments is not convenient. Therefore, it is of great significance to develop a high precision, low power consumption and high stability in situ nitrate detection instrument with independent intellectual property rights in China. On the basis of analyzing the development of advanced nitrate detection instruments at home and abroad, this paper synthetically applies the knowledge of optics, physics, mechanics, electronics and computer science and technology, etc. The design of in situ detection instrument based on ultraviolet spectrophotometry, including mechanical optical circuit, electronic circuit, algorithm and software interface, has been developed with high precision and low power consumption. A stable in-situ nitrate detection device. The experimental results show that the detection accuracy of the marine nitrate in situ detection instrument is as high as 0. 9988 渭 mol/1;, the linear range of detection is 1-320 渭 mol/1; and the mean square deviation is 0. 009551. The system has good performance and reaches the international level of the same kind of nitrate in situ detector. There are six chapters in this paper: the first chapter describes the research background and significance of the thesis, introduces the common detection methods of nitrate, and the nitrate detection method used in water body. Finally, a set of marine nitrate in situ detection scheme based on ultraviolet spectrophotometry is proposed. In the second chapter, the principle of ultraviolet spectrophotometry and the ultraviolet spectrum of common marine substances are introduced. The third chapter introduces the design of marine nitrate in situ detection system, including system design, mechanical design, hardware design and so on. The fourth chapter introduces the software design of marine nitrate in-situ detection system, including software requirement description, system software design, interface design, communication design, data algorithm design and so on. The fifth chapter introduces the design of the experiment and the analysis of the experimental results. The sixth chapter is the summary and prospect.
