Description

technical field

[0001] The invention belongs to the technical field of temperature measurement, and in particular relates to a coupling-based non-contact temperature measurement system and a measurement method thereof. Background technique

[0002] In daily life and industrial production process, it is often necessary to measure the temperature of various objects. Temperature is a very important index parameter in many technical fields. In many fields such as industry, medical treatment, military affairs and life, temperature measuring devices are required to monitor temperature. The automatic monitoring of temperature has become one of the important measures for safe production and loss reduction in all walks of life. In certain occasions, due to the scattered and remote monitoring points, the traditional temperature measurement method has a long period and high cost, and the surveyor must go to the site to measure, so the work efficiency is very low.
