智能红外测温仪的测量影响因素研究OA

Objective By analyzing the working principle of the intelligent infrared thermometer and conducting temperature measurement experiments on the human body for verification,to study the influence of various factors such as the distance and angle between the measurement target and the intelligent infrared thermometer,as well as environmental temperature and humidity,on the results of the intelligent infrared thermometer.Methods Based on the principle of infrared temperature measurement,a walk-in environmental test chamber was used to simulate the temperature measurement conditions of the intelligent infrared thermometer under different temperatures and humidity.The data were analyzed using SPSS 22.0 statistical software,fully considering the influence of multiple factors such as distance,angle,temperature and humidity on the intelligent infrared thermometer.Results When only height was considered,there was a statistically significant difference in the measurement results of volunteers with a height of 190 cm using a glass thermometer and an intelligent infrared thermometer(P<0.05).There was no statistically significant difference in the measurement results between the glass thermometer and the intelligent infrared thermometer of the volunteers with a height of 160 cm(P>0.05).The measurement results were less affected by angle changes.However,angle alterations could have an impact on the measurement data(resulting in lower measurement values),especially when the measurement distance increased.When only the environmental temperature and humidity were considered as single factors,there were statistically significant differences in the measurement data when comparing the ambient temperature between 25℃and 35℃,as well as between 25℃and 10℃,and between 35℃,30%RH and 35℃,80%RH(P<0.05).With the interference of multiple factors,the accuracy of the measurement data would decline(the measured value will be lower).When considering the simultaneous interference of multiple factors such as distance,height and humidity,the maximum relative error was 2.7%and the maximum error was 1℃.Conclusion In practical application,the effective measurement distance of the intelligent infrared thermometer and the influence of environmental temperature and humidity on the temperature measurement results should be fully considered.When measuring temperature,the person being measured should be kept within the effective measurement distance.When the environmental temperature and humidity are too low or too high,measures should be taken to maintain the stability of temperature and humidity in the usage site and reduce the impact caused by adverse environmental factors.
