Technical Field
The utility model relates to the field of sensors, in particular to a protective structure of an infrared thermal imaging temperature measurement sensor.
Background
In nature, random movements of molecules and atoms exist in any object above absolute zero (-273 ℃), and the object continuously releases infrared radiation energy outwards. The size and wavelength of the radiation energy are closely related to the surface temperature of the object, the infrared thermal imaging temperature measurement sensor optical system can collect the radiation energy and focus the radiation energy and transmit the radiation energy to the photoelectric detector to be converted into a series of electric signals, and the electric signals are processed by a series of algorithms arranged in the signal processing circuit, so that accurate temperature measurement aiming at the measured object can be realized. The infrared thermal imaging temperature measurement sensor has the advantages that the lens cannot be directly irradiated by sunlight or shielded by foreign matters during temperature measurement due to the non-contact and infrared sensing temperature measurement characteristics of the infrared thermal imaging temperature measurement sensor. In practical application scenarios (especially in outdoor application), if the lens of the infrared thermal imaging temperature measurement sensor is directly exposed in an outdoor environment, the temperature measurement function is easily limited or lost due to direct sunlight, rain wash, snow cover and other influences.
Therefore, a protection structure of the infrared thermal imaging temperature measurement sensor is needed.
