Hot blast stove plays an important role in the field of industrial ironmaking. Therefore, it is necessary to measure and monitor the temperature of hot blast stove. However, the traditional method of temperature measurement has some shortcomings, such as high cost and inconvenience. Therefore, Jinan Thermal Energy Equipment Co., Ltd. proposes a new method of temperature measurement, distributed optical fiber temperature measurement, and applies it to the field. Hot blast stove. Distributed optical fiber temperature measurement technology is a new high-tech for real-time measurement of spatial temperature field data in recent years. It is based on optical ti彩色沥清地坪me domain reflectometry (OTDR) and Raman scattering temperature measurement principle.
由於該技術的重點部分是信號解調,因而本文綜合研究分佈式光纖測溫的多種解調方法及熱風爐測溫特點,創新性的提出采用雙端雙路解調法(DTDC)。分三個部分介紹瞭基於DTDC解調法的分佈式光纖測溫技術在成都找人公司上的應用。首先,以成都***為研究對象,介紹瞭課題的研究背景及意義、成都***測溫和分佈式光纖測溫的國內外研究現狀,以及提出新型解調方式的必要。
Because the key part of this technology is signal demodulation, this paper synthetically studies various demodulation methods of distributed optical fiber temperature measurement and the characteristics of hot blast stove temperature measurement, and innovatively proposes a dual-terminal dual-channel demodulation method (DTDC). The application of distributed optical fiber temperature measurement technology based on DTDC demodulation in hot blast stove is introduced in three parts.

其次,從熱風爐測溫的發展及現有的解調方法等理論部分出發,提出問題,然後針對相應的問題提出解決方案,並以此得到系統的整體結構設計,主要分為硬件和軟件兩大模塊。硬件結構主要由光源、傳感光纖、光開關、波分復用器(WDM)、光電檢測器以及FPGA與DSP結合的信號采集與處理模塊組成;軟件模塊則包含瞭數據的采集、去噪、解調的程序設計,以及环境配置,硬件與上位機部分連接的程序設置。
Secondly, starting from the development of hot blast stove temperature measurement and the existing demodulation methods, this paper puts forward some problems,透水地坪 and then puts forward solutions to the corresponding problems, and obtains the overall structure design of the system, which is mainly divided into hardware and software modules. The hardware structure is mainly composed of light source, sensing optical fiber, optical switch, wavelength division multiplexer (WDM), photoelectric detector and signal acquisition and processing module combined with FPGA and DSP. The software module includes the program design of data acquisition, denoising and demodulation, as well as the environment configuration, and the program settings of the connection between hardware and PC.
最後,對軟件與硬件結合的測溫系統進行性能測試,先於實驗室中對不同的解調方式進行對比研究,得出DTDC尤於其它解調法,然後測試系統的測溫精度及分辨率,結果滿足熱風爐工業現場要求。本文致力於將分佈式光纖測溫的最新研究成果應用於某鋼鐵的熱風爐測溫系統,並對系統的測溫精度及空間分辨率進行測試。測試結果表明,濟南廠傢熱能設備有限公司的設備系統安裝方便,可測量的溫度范圍在-10~200℃之間,最大測溫誤差不超過0.5℃,定位精度為0.5m,滿足工業要求,在熱風爐測溫領域有著良好的理論意義與應用前景。

It is concluded that DTDC is better than other demodulation methods by comparing different demodulation methods in the laboratory. Then the temperature measurement accuracy and resolution of the system are tested. The results meet the requirements of hot blast stove industrial field. This paper is devoted to applying the latest research results of distributed optical fiber temperature measurement to a hot blast stove temperature measurement system of iron and steel, and testing the temperature measurement accuracy and spatial resolution of the system. The test results show that the equipment system of Jinan Thermal Energy Equipment Co., Ltd. is easy to install. The range of temperature can be measured is - 10 ~ 200 C.
