The current calibration model for thermocouple temperature sensors is generally an independent calculation structure,and the overall efficiency of calibration is low,which leads to an increase in the error of calibration indication.Therefore,a design of a thermocouple temperature sensor calibration method based on an improved grey wolf algorithm is proposed.By introducing an improved grey wolf algorithm,the measurement efficiency and accuracy of thermocouples are effectively improved,and the expanded uncertainty is reduced.Based on the current calibration requirements,first collect temperature sensing data and set calibration standards for calibration.Adopting a multi-stage approach to improve the overall efficiency of calibration,construct a multi-stage improved grey wolf calculation calibration model,and use adaptive comparison correction to achieve calibration processing.The test results show that for the set temperature range of 20℃to 1 200℃,after three cycles of measurement,the mean error of the final calibration indication is well controlled below 1.59℃,indicating that with the assistance of the improved grey wolf algorithm,the designed thermocouple temperature sensor calibration method is more efficient,targeted,and has practical application value.
