Description
Technical Field
The utility model belongs to the technical field of body temperature check out test set, concretely relates to infrared body temperature measuring device.
Background
The temperature measuring principle of the infrared thermometer is the blackbody radiation law, as is well known, all objects higher than absolute zero in nature continuously radiate energy, the magnitude of the outward radiation energy of the object and the distribution of the outward radiation energy according to the wavelength are closely related to the surface temperature of the object, and the higher the temperature of the object is, the stronger the emitted infrared radiation capability is.
The infrared thermometer uses infrared detector, optical imaging object lens and optical scanning system (advanced focal plane technology omits optical scanning system), receives the infrared radiation energy distribution pattern of the measured object and reflects it on the photosensitive element of the infrared detector, between the optical system and the infrared detector, there is an optical scanning mechanism (the focal plane thermal imager has no such mechanism) to scan the infrared thermal image of the measured object and focus on the unit or the light splitting detector, the detector converts the infrared radiation energy into electric signal, the infrared thermal image is displayed by the TV screen or monitor after amplification, conversion or standard video signal. This thermographic image corresponds to the thermal distribution field of the object surface; in fact, because the thermal image distribution map of infrared radiation of each part of the measured target object is very weak in signal and lacks gradation and stereoscopic impression compared with a visible light image, in order to more effectively judge the infrared thermal distribution field of the measured target in the actual action process, some auxiliary measures are often adopted to increase the practical functions of the instrument, such as the control of image brightness and contrast, real standard correction, pseudo color drawing and other technologies.
The common infrared thermometers include an infrared thermal imaging thermometer and an infrared thermometer. The temperature measured by the non-contact infrared thermometer at present is greatly different from the actual temperature, the efficiency is low, thousands of pigs in the whole pigsty cannot be rapidly detected and effectively recorded, and the price is high and the pigsty is easy to break.

The prior art has many disadvantages, and the temperature measured by the prior art infrared imaging thermometer has an error of about 5%, which is fatal and expensive to improve its accuracy. The sensitivity of the chip is high, the price is high, the service life is long, and the accuracy of the sensor is influenced.
The image contrast is low, the detail resolving capability is poor, because the infrared thermal imager is imaged by temperature difference, and the temperature difference of a common target is not large, the infrared thermal image contrast is low, and the detail resolving capability is poor.
