Skin physiological index measuring device and method

Abstract

The invention provides a skin physiological index measuring device and a measuring method. The device comprises an infrared temperature measuring sensor module, an infrared transmitting module, a photosensitive sensor module and a processor, wherein the infrared temperature measuring sensor module is used for continuously collecting multiple groups of detected skin temperature data of a detected skin area of a detected object; the infrared transmitting module is used for transmitting infrared light and continuously collecting multiple groups of infrared spectrum data reflected by the detectedskin area of the detected object; the photosensitive sensor module is used for continuously collecting multiple groups of brightness data of the detected skin area of the detected object and the photosensitive sensor module, on the basis of the collected brightness data, is used for acquiring multiple groups of detected skin sweat gland secretion data; and the processor is connected to the infrared temperature measuring sensor module, the infrared transmitting module and the photosensitive sensor module, and the processor is used for receiving the multiple groups of detected skin temperature data, multiple groups of infrared spectrum data and multiple groups of skin sweat gland secretion data and obtaining an emotional fluctuation result of the detected object on the basis of the receiveddata.

Description

technical field [0001] The invention relates to the field of physiological index measurement, research and identification, and relates to a multi-part skin physiological index measuring device and method. Background technique [0002] In the field of psychology, according to statistics, the real-time monitoring and management of emotions (including tension, anger, fear, jealousy, sadness, happiness, happiness, etc.) is a very difficult thing, and usually only some questionnaires are used. This traditional evaluation method is difficult to achieve continuity, and the subjects may hide their inner choices. The subjective component is very large, and it is difficult to rule out the influence of human factors. It is only a rough subjective evaluation. Immediate, continuous and objective recording and analysis of emotional states cannot be carried out. [0003] Emotions can be divided into positive (positive) emotions and negative (negative) emotions. Positive emotions and negat...

AI Technical Summary

Problems solved by technology

Existing mechanical devices cannot complete a certain task without human control, and must be controlled by humans at a certain stage

In the existing technology, people can only send instructions to mechanical equipment with the help of external equipment, but cannot control mechanical equipment through the collection of human physiological signals, and cannot use my current physiological index status to control mechanical equipment

Human and machine artificial intelligence that cannot really be done

[0006] At present, the problems in emotion recognition in the field of psychology, human factor interference in the field of human factors engineering, and design and analysis of ergonomics are that it is impossible to collect effective physiological data and analyze objective physiological data.

Most of the existing non-contact radiation thermometers use temperature guns to measure forehead temperature. What is actually measured is body temperature, which cannot be used to automatically and quickly measure changes in skin temperature. There is no reference for psychological measurement Significance, and the temperature measurement results of this method are easily affected by the temperature measurement angle and measurement field of view, and cannot achieve single-point temperature measurement

When the angle between the temperature measurement unit of the temperature measurement gun and the object to be measured is relatively large, the received radiation energy will be greatly reduced, and the temperature measurement results will become unreliable; in addition, when the object to be measured is smaller than the measurement field of view, the background A large amount of radiant energy will enter the temperature measurement module of the thermometer and interfere with the temperature measurement reading. At this time, the temperature measurement of the thermometer is the weighted average of the temperature of the object to be measured and its background temperature, resulting in measurement errors

In addition, the skin temperature of the tested skin is easily affected by the temperature of the environment. If only this parameter is used to judge the psychological state and emotion of the subject, it is easy to produce relatively large errors
