Abstract

The invention relates to a non-contact infrared thermometer. The non-contact infrared thermometer comprises a DC-DC (direct current-direct current) converter, a power supply management circuit, a temperature sensing circuit, an analog-digital converter, a central processor, a clock circuit interface, a crystal oscillator, an analog signal amplifier, an amplification circuit interface, FLASH memory, an IIC (Inter-Integrated Circuit) communication interface, a keyboard interface, an LCD (Liquid Crystal Display) drive circuit, a backlight control circuit, a buzzer drive circuit, a buzzer module, a keyboard, a backlight lamp and an LCD display screen, wherein the analog signal amplifier is used for receiving an analog electric signal which s output by a photoelectric detector; and the central processor is used for converting the analog electric signal into a corresponding temperature value and performing associative memory of the temperature value and time in the FLASH memory according to the time for generating the temperature value. The non-contact infrared thermometer is capable of performing associative memory of the temperature value and time, so that a user can know change of own body temperature in a period of time and conveniently know own physical condition.

Description

[0001] technical field [0002] The invention relates to a non-contact infrared thermometer. [0003] Background technique [0004] Body temperature is the basic characteristic of human life activities, and it is also one of the important indicators to observe whether the human body functions normally. In current daily life, people use the most widely used mercury thermometer, which judges the temperature value by reading the scale value according to the properties of mercury, etc., that expand with heat and contract with temperature. However, the glass loaded with mercury is easy to break and poses a safety hazard. In view of this, a non-contact infrared thermometer has appeared on the market, which can obtain the photoelectric signal of the human body through the photodetector, and then convert the temperature value to the processor. However, the non-contact infrared thermometer cannot store the measured data, and the user cannot observe changes in his own body temperat...
