【摘要】：溢油是水體中的主要污染物之一,而溢油事故多發(fā)于海洋鉆井平臺(tái)、輸油管線以及船舶航行過(guò)程中。溢油產(chǎn)生后會(huì)隨著水流進(jìn)一步擴(kuò)散從而造成大面積的水域污染,及早發(fā)現(xiàn)溢油事故,根據(jù)不同種類的溢油采取行之有效的處理辦法則可以有效地降低溢油對(duì)環(huán)境的污染,減少經(jīng)濟(jì)損失。紫外誘導(dǎo)熒光探測(cè)水面溢油是目前探測(cè)效率最好,識(shí)別精度最高的探測(cè)方法,其具有預(yù)警精度高,全天候探測(cè)的特點(diǎn),可探測(cè)到微米級(jí)別的油膜,也是目前唯一一種能夠探測(cè)冰面、雪地以及沙石表面的技術(shù)手段。本文從能級(jí)激發(fā)的角度討論了紫外光誘導(dǎo)熒光的原理,歸納總結(jié)了熒光激發(fā)速率方程以及影響熒光激發(fā)效率的因素。通過(guò)搭建溢油探測(cè)實(shí)驗(yàn)平臺(tái),分別在暗室與實(shí)驗(yàn)室環(huán)境下完成了不同油品的熒光激發(fā)探測(cè),得出了相應(yīng)的油品辨別公式。實(shí)驗(yàn)了不同厚度油品的熒光激發(fā)強(qiáng)度,歸納總結(jié)了熒光強(qiáng)度隨油膜厚度變化的原因,實(shí)驗(yàn)了不同探測(cè)高度下油品的熒光強(qiáng)度,為日后光強(qiáng)補(bǔ)償提供了實(shí)驗(yàn)數(shù)據(jù)與理論依據(jù)。搭建并測(cè)試了光電傳感器的信號(hào)濾波電路,設(shè)計(jì)了熒光激發(fā)系統(tǒng)、信號(hào)接收系統(tǒng)及其遮光結(jié)構(gòu),使用TracePro仿真軟件對(duì)遮光結(jié)構(gòu)的遮光效果進(jìn)行了驗(yàn)證。溢油預(yù)警控制系統(tǒng)采用兩個(gè)STC89C58單片機(jī),分為主機(jī)與從機(jī)協(xié)同工作,通過(guò)對(duì)比選擇引入了AD模塊,測(cè)距傳感器、顏色傳感器、溫濕度傳感器、無(wú)線通信模塊、顯示模塊、時(shí)鐘模塊以及語(yǔ)音預(yù)警等模塊,使系統(tǒng)的功能更加全面,進(jìn)一步提高了探測(cè)效率。通過(guò)C語(yǔ)言對(duì)上述各個(gè)模塊分別進(jìn)行編程并調(diào)試運(yùn)行,運(yùn)用均值濾波算法以及卡爾曼濾波算法對(duì)熒光信號(hào)進(jìn)行了濾波處理,使探測(cè)信號(hào)更加穩(wěn)定。設(shè)計(jì)了預(yù)警系統(tǒng)的運(yùn)行邏輯,設(shè)置了兩種探測(cè)模式,通過(guò)對(duì)單片機(jī)的編程實(shí)現(xiàn)了系統(tǒng)的實(shí)時(shí)遠(yuǎn)程遙感與自動(dòng)預(yù)警功能,完成了溢油的預(yù)警以及溢油種類的識(shí)別。
[Abstract]:Oil spill is one of the main pollutants in the water body, and oil spill accidents often occur in offshore drilling platforms, oil pipelines and ships. Oil spills will spread further with the flow of water, resulting in a large area of water pollution. Early detection of oil spill accidents and effective treatment according to different oil spills can effectively reduce environmental pollution and reduce economic losses. UV induced fluorescence detection of oil spills on water surface is the best detection efficiency at present. The detection method with the highest accuracy is characterized by high warning accuracy and all-weather detection. It can detect micrometer oil film and is the only one capable of detecting ice surface at present. In this paper, the principle of UV induced fluorescence is discussed from the point of view of energy level excitation. The equation of fluorescence excitation rate and the factors influencing the efficiency of fluorescence excitation are summarized. The fluorescence excitation detection of different oil products is accomplished in dark room and laboratory environment by setting up an oil spill detection experimental platform. The corresponding oil discrimination formula was obtained. The fluorescence excitation intensity of oil with different thickness was tested, the reasons of the change of fluorescence intensity with oil film thickness were summarized, and the fluorescence intensity of oil product at different detection heights was tested. It provides experimental data and theoretical basis for light intensity compensation in the future. The signal filter circuit of photoelectric sensor is built and tested, and the fluorescent excitation system, signal receiving system and its shading structure are designed. The TracePro simulation software is used to verify the shading effect of the shading structure. Two STC89C58 microcontrollers are used in the oil spill early warning control system, which is divided into two parts: the host computer and the slave computer. The AD module, the ranging sensor and the color sensor are introduced through comparison and selection. Temperature and humidity sensor, wireless communication module, display module, clock module and voice warning module make the function of the system more comprehensive. The detection efficiency is further improved. Each module mentioned above is programmed and debugged by C language, and the fluorescence signal is filtered by means of mean filter algorithm and Kalman filter algorithm. The operating logic of the early warning system is designed and two detection modes are set up. The real-time remote sensing and automatic warning functions of the system are realized by programming the single chip computer. The warning of oil spill and the recognition of oil spill type are completed.
