Problems solved by technology

The above-mentioned patents have the following shortcomings: the lack of a distance conversion mechanism, resulting in the inability to adjust the multiples of the temperature data collected at a long distance, which makes the temperature value calculated based on the data deviate greatly from the actual situation, and the distance conversion cannot be realized. The initial data obtained by the instrument is greatly disturbed by the environment

Abstract

The invention discloses an infrared temperature measurement module based on a thermopile, and relates to the technical field of body temperature measurement. The invention aims to solve the problem that temperature measurement is greatly influenced by the distance. The module specifically comprises a core assembly and a placement assembly; the core assembly comprises a device box and an MCU processor control panel; and a thermopile infrared sensing chip, a distance sensing module, a high-precision NTC chip, a matching module and an external equipment interface are electrically installed on theouter wall of the top of the MCU processor control panel, wherein the thermopile infrared sensing chip is electrically connected with a thermopile infrared sensor, and the distance sensing module iselectrically connected with a distance sensor; and a driving module is arranged in the MCU processor control panel and comprises a temperature calculation program and an environment compensation program. The matching module can perform zooming-in or zooming-out processing on the human body temperature measured in a centimeter range, and is matched with an environment compensation program and a temperature calculation program, so that the measured temperature error is smaller than 0.1 DEG C.

Description

technical field [0001] The invention relates to the technical field of body temperature measurement, in particular to an infrared temperature measurement module based on a thermopile. Background technique [0002] Most of the existing infrared temperature measuring instruments directly use temperature sensors for data collection, but lack the corresponding compensation mechanism. A small number of temperature measuring instruments using thermopile technology also have the problem of limited environment, which needs to be solved systematically The above problems require a new type of infrared temperature measurement module based on thermopile. [0003] After searching, the Chinese patent application number is 201610100597.6, which discloses a non-contact switch cabinet contact infrared thermopile temperature measuring ring, including: a ring-shaped shell and an induction power-taking device located in the shell, storage The energy and power processing circuit, the signal acq...
