The mercury thermometer has the disadvantages of long measuring time, difficult reading and potential dangers, such as fragile glass and toxic mercury volatilization; the digital thermometer is easily influenced by the ambient temperature, and the measurement precision can be reduced when the ambient temperature difference is large. The infrared thermometer measures temperature reading by using a black radiation principle, adopts an infrared sensor to only absorb infrared rays radiated by an object without emitting any rays to the outside, senses temperature by a non-contact method, and has the advantages of short measuring time, convenience in reading, safety in use and the like.
Although there are many forms of infrared temperature measurement, the principle is consistent, that is, all objects whose temperature is higher than absolute zero emit a certain proportion of infrared radiation energy according to their own temperature, and the size and the wavelength distribution are closely related to the surface temperature of the object. The infrared temperature measuring equipment developed according to the principle can accurately measure the surface temperature of an object.

Meanwhile, the error is larger because the temperature measuring distances are different in various occasions.
One important reason for the error is that when the infrared thermometer is used, the size of the infrared field of view changes with the change of the measurement distance, and the change rule is different according to the difference of the focusing of the optical lens, which can be generally understood as that the infrared thermometer is the smallest at the focal point and gradually increases after being out of focus, because the infrared thermometer measures the average temperature in the field of view, and the data obtained by taking the average temperature when the field of view is large are more, and the temperature of an irrelevant object around the target object may be taken in, thereby causing the error.
The invention aims to solve the technical problems and provides an infrared temperature detector which adopts a distance measuring sensor arranged at the front end of a temperature detector main body side by side with the temperature measuring sensor to measure the temperature at each time, provides field-of-view information according to parameters such as field angle and the like and gives a prompt.
