Abstract

The invention provides a temperature measurement calibration method of non-contact equipment and the non-contact equipment. The temperature measurement calibration method comprises the following steps: acquiring a sampling temperature of a heat source at a constant experimental environment temperature; processing the sampling temperature of the heat source and the output temperature of the heat source according to a preset rule to obtain a compensation value; and processing the measured temperature acquired in real time according to the compensation value and a preset correction algorithm to obtain a corrected temperature. Compared with the prior art, the temperature measurement accuracy of the non-contact temperature measurement equipment can be improved.

Description

technical field [0001] The invention relates to a measuring device, in particular to a temperature measurement and calibration method of a non-contact device and the non-contact device. Background technique [0002] In recent years, with the development of technology, smart devices have become more and more popular. Moreover, with the miniaturization of electronic devices, various types of smart devices, especially wearable devices, have multiple functions, such as waterproof performance, temperature measurement, etc., to meet the growing social needs of the public. [0003] At present, most non-contact devices, such as wearable devices such as watches, are usually equipped with non-contact devices, such as through thermal induction and other principles, to achieve non-contact temperature measurement. Moreover, when designing some non-contact devices, such as wearable devices such as watches and other devices, it is necessary to consider not only having a non-contact temper...
