【摘要】：在石化、電力、冶金等行業(yè)中,溫度是生產(chǎn)過程中關(guān)鍵參數(shù)之一,對提高生產(chǎn)質(zhì)量和生產(chǎn)率、節(jié)能降耗、保障安全生產(chǎn)都起到極為重要的作用。熱電偶、高溫輻射計、測溫槍、熱像儀、光纖測溫儀等等測溫設(shè)備在這些行業(yè)中均得到廣泛應(yīng)用,其中光纖測溫儀應(yīng)其抗干擾能力強、體積小、柔性好等特點,往往被用于某些特殊環(huán)境中。然而,傳統(tǒng)的光纖紅外測溫儀是利用單根光纖測量目標表面某一點的溫度,而當(dāng)需要面進行溫度分布監(jiān)測時,則無能為力(如鋼水精煉,需區(qū)分鋼水和鋼渣并對鋼水溫度進行有效檢測)。本課題提出了一種基于光纖束陣列的紅外成像測溫方法,有效解決了上述問題。隨著纖維光學(xué)技術(shù)的不斷發(fā)展,光纖作為纖維光學(xué)的一種元件在醫(yī)學(xué)領(lǐng)域、工業(yè)領(lǐng)域、軍事及安全領(lǐng)域、科研領(lǐng)域等得到了非常廣泛的應(yīng)用。因此,本課題實驗裝置是利用光纖傳像束的成像原理以及近紅外網(wǎng)絡(luò)面陣探測器,基于比色測溫原理測量溫度的。本論文主要完成以下幾個方面的工作:1.從熱輻射學(xué)中幾大定律推導(dǎo)出雙波長比色測溫公式和設(shè)備因子K值表達式,闡述了本課題的理論研究方法,利用光纖傳像束與近紅外CCD藕接攝取熱圖像及靶標識別,再根據(jù)比色測溫公式計算出靶標溫度;2.根據(jù)實驗操作需要,設(shè)計測溫裝置系統(tǒng),主要有光纖傳像束及近紅外熱成像傳感器、高溫鏡頭,說明了比色測溫數(shù)據(jù)處理系統(tǒng)以及軟件工作流程;3.為了提高測量準確度,減小實驗誤差,對系統(tǒng)中幾個關(guān)鍵技術(shù)進行優(yōu)化,比如紅外波段選取、設(shè)備因子K值的標定等,對紅外圖像的處理、有效數(shù)據(jù)的提取;4.在實驗室進行實驗及對實驗數(shù)據(jù)處理,擬合公式并反向驗證;5.對實驗數(shù)據(jù)進行分析。
[Abstract]:In petrochemical, electric and metallurgical industries, temperature is one of the key parameters in the production process, which plays an extremely important role in improving production quality and productivity, saving energy and reducing consumption, and ensuring safe production. Thermocouple, high-temperature radiometer, thermometer gun, thermal imager, optical fiber thermometer and so on are all widely used in these industries. Among them, fiber optic thermometer has the characteristics of strong anti-interference ability, small volume, good flexibility and so on. It is often used in certain special circumstances. However, the traditional fiber-optic infrared thermometer uses a single optical fiber to measure the temperature at a point on the surface of the target, but there is no way to monitor the temperature distribution when the surface is needed (for example, molten steel refining, It is necessary to distinguish molten steel from slag and to detect the temperature of molten steel effectively. In this paper, a method of infrared imaging temperature measurement based on fiber beam array is proposed, which effectively solves the above problems. With the development of fiber optics technology, optical fiber has been widely used in medical, industrial, military and security fields, as a component of fiber optics. Therefore, the experimental device uses the imaging principle of optical fiber image beam and the near infrared network array detector to measure temperature based on the principle of colorimetric temperature measurement. This paper mainly completes the following aspects of work: 1. Based on several laws of thermal radiology, this paper deduces the formula of double wavelength colorimetric temperature measurement and the expression of K value of equipment factor, and expounds the theoretical research method of this subject. The optical fiber image beam is used to connect with the near infrared CCD to capture the thermal image and the target recognition. Then the target temperature is calculated according to the colorimetric formula. According to the need of experiment operation, the temperature measuring device system is designed, including optical fiber image transfer beam and near infrared thermal imaging sensor, high temperature lens. The data processing system of colorimetric temperature measurement and the software work flow are described. In order to improve the accuracy of measurement and reduce the experimental error, several key techniques in the system are optimized, such as the selection of infrared band, the calibration of K value of equipment factor, the processing of infrared image and the extraction of effective data. The experiment is carried out in the laboratory and the experimental data is processed, the formula is fitted and the reverse verification is carried out. The experimental data are analyzed.
