Problems solved by technology
[0004] In order to solve the technical problem of being unable to accurately measure human body temperature in the prior art, the present invention provides a device and method for measuring human body temperature based on an infrared temperature sensor. Multi-point temperature sampling is carried out at multiple sampling points inside, and the sampling temperature that obviously does not belong to the temperature range of the human body is eliminated, and the remaining effective temperature is averaged to obtain more accurate body temperature data, which greatly reduces the interference of ambient temperature and realizes Real-time, fast, non-contact human body temperature measurement

Embodiment Construction
[0017] In order to describe the principle and technical solution of the present invention, the following detailed description will be given in conjunction with the accompanying drawings. The examples given are only for explaining the present invention, not for limiting the scope of the present invention.
[0018] The body temperature of a normal human body is generally 36.1°C to 37°C, which is about 0.2°C to 0.4°C lower than the oral temperature. According to the degree of fever (oral temperature), it can be divided into: low fever: 37.4°C to 38°C; moderate heat: 38.1 ℃~39℃: high fever: 39.1℃~41℃; super high fever: above 41℃. In this invention, the effective temperature range of the human body is set as 35℃~42℃. Only when the collected temperature falls into the above effective temperature range , it is considered as an effective temperature; otherwise, it means that the corresponding sampling point does not belong to the human body area or the human body area is blocked by ot...

The invention relates to a device for measuring the temperature of a human body.An infrared temperature sensor is used for carrying out temperature sampling on M*N sampling points, M is larger than or equal to 3, and N is larger than or equal to 3.The device is characterized in that the temperature measured at each sampling point is compared with the effective temperature section of the human body, the temperatures within the effective temperature section of the human body are averaged, and the obtained average temperature is the temperature of the human body.According to the device, the temperatures of the sampling points including a measured object are collected, so that the defect that a single-point temperature measuring mode is prone to be influenced by the environment is effectively overcome, the influence that the sampled temperatures are abnormal due to the outside of the human body and shielding of clothes is eliminated through effective temperature screening, the accuracy of body temperature measurement is improved, the temperature of a measured person can be mastered in real time, and life of people is convenient.
Description
technical field [0001] The invention relates to a method for measuring body temperature, in particular to a device and method for measuring body temperature based on a multi-point infrared temperature sensor. Background technique [0002] In recent years, with the development of infrared temperature measurement technology, non-contact infrared thermometers have developed rapidly, their performance has been continuously improved, and their functions have been continuously enhanced. Compared with contact temperature measurement methods, infrared temperature measurement has the advantages of fast response time, non-contact, safe use and long service life. Infrared detection is an online monitoring high-tech detection technology, which integrates photoelectric imaging technology, computer technology, and image processing technology. By receiving infrared rays (infrared radiation) emitted by objects, the thermal image is displayed on the fluorescent screen, so as to accurately ju...
