Abstract

The invention discloses a non-contact infrared thermometer. The non-contact infrared thermometer comprises a non-contact infrared temperature sensor, a temperature difference thermopile amplifying circuit, a temperature compensating and amplifying circuit, an A/D (analog/digital) conversion circuit, a master control circuit, a display circuit and an alarming circuit. The non-contact infrared temperature sensor is connected with the temperature difference thermopile amplifying circuit and the temperature compensating and amplifying circuit; the temperature difference thermopile amplifying circuit and the temperature compensating and amplifying circuit are connected with each other and connected to the A/D conversion circuit respectively; the A/D conversion circuit is connected with the master control circuit; the master control circuit is connected with the display circuit and the alarming circuit. The non-contact infrared thermometer solves the problem that traditional thermometers require contact measurement and meets the requirements of people on novel temperature taking modes through relatively short response time and high measuring precision and accuracy. Meanwhile, the non-contact infrared thermometer is free from interference of environmental factors and the like, stable in performance, convenient to read, capable of achieving the aim of real-time monitoring and applicable to care for old people, children and patients.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a non-contact infrared thermometer. Background technique [0002] With the comprehensive development of economy and society, health has become a problem that people pay more and more attention to. As a warm-blooded animal, body temperature is undoubtedly an important indicator to measure the health of the human body. Real-time monitoring of the basic physiological parameters of body temperature can enable us to intuitively grasp whether the body's life activities are normal. Therefore, thermometers have become a must for daily family Basic medical equipment for equipment and clinical medicine. Mercury thermometer has become the most widely used body temperature measurement tool at present due to its low price, relatively stable performance and relatively accurate measurement results. However, its disadvantages have also attracted people's attention day by day. , the broken ...
