摘要
旨在开展红外辐射测温系统研究,以探测器像元所接收的目标辐照度为基础,详细分析了红外探测系统的信噪比、灵敏度和探测误差,介绍了系统的结构设计及关键参数,并对系统面均匀性进行了细致的校准。针对工业现场特殊应用环境,建立系统背景补偿模型进行对比实验和连续观测实验,对比结果:平均值相差0.15℃,标准差4.4℃,满足工业现场温度测量精度要求;连续观测实验与裂解炉实际运行情况完全一致,表明该系统能够解决管式工业炉炉管表面温度连续实时监测的技术难题。
Abstract
This paper is focusing on studying the Infrared radiation temperature measurement system. The signal-to-noise ratio, sensitivity and detection accuracy of infrared detection system is analyzed in detail based on the target irradiance received by the detector pixels in the unit solid angle. Structure design and key parameters of the infrared detection system was introduced and calibration of the surface uniformity was carried out in detail. The background compensation model is set up for industrial field experiment. Then comparison experiments between the infrared detection system and the infrared radiation thermometer were implemented. The experiment results show mean difference is 0.15℃ and standard deviation is 4.4℃, so it can satisfy the requirements of industrial field temperature measurement accuracy. And technical challenge of temperature monitoring for tube surface is solved in high temperature environment.
