一、前言对于一类工业过程如窑炉等不可能利用热电偶直接测量工件表面温度,间接量测则具有较大的时延和测量误差.采用红外测温计虽然可以直接测量工件表面温度,但具有较大的随机误差.针对这类工业过程的特点,本文试图利用热电偶具有较高的精度以及红外测温计比较敏感的特点,提出了一种基于双通道检测的自校正算法.该算法对双通道
I. Introduction For a class of industrial processes such as furnaces can not use the thermocouple direct measurement of the surface temperature of the workpiece, indirect measurement has a greater delay and measurement error. Although the use of infrared thermometer surface temperature can be measured directly, But with a large random error.Aiming at the characteristics of these industrial processes, this paper attempts to use a thermocouple with high accuracy and infrared thermometer is more sensitive characteristics of a self-calibration algorithm based on dual-channel detection. Algorithm for dual channel
