Description
Technical field
The present invention relates to physical signs measuring studies to identify field, is related to multiple location skin physiology instrument for measuring index and side
Method.
Background technology
Psychological field, according to statistics, the reality of mood (including nervous, indignation, frightened, envy, sad, happy, happiness etc.)
When monitoring and management be a very difficult thing, it is common only to be carried out by the way of some questionnaire surveys.Traditional
This appraisal procedure is difficult to accomplish continuity, and subject personnel may hide the option of heart, and subjective ingredient is very big, it is difficult to arrange
Except artificial factor influences, only rough carry out subjective evaluation.Can not carry out it is instant, continuous, objectively remembered
Record and analysis emotional state.
Mood can be divided into positive (just) mood and passive (negative) mood, active mood and negative feeling in psychological field or
Tool has very important significance in person's physical and mental health, but the prior art can not accomplish that the correlation of continuous objectively record subject is raw
Data are managed, and behavior or psychological guidance are preferably carried out for subject by subsequent analysis.
Ergonomics field, ergonomics design field, be designed according to the characteristics of human body meet human body operation,
The product of layout.Ergonomic at the beginning of product design be parsed into how the standard of deisgn product.Such as automobile cab
Whether the design of each structure meets the primary demand of people, and whether long-duration driving is because fatigue problem generates psychology variation；Than
Whether the driver's cabin of such as aircraft, passenger compartment seat design meet the long-time sitting posture demand of people.But current technology mainly from
The angle of simple seat design is set out, and is not measured by comparing the acquisition comparative analysis of the physiological data of science.
Artificial intelligence field, artificial intelligence are to confer to the intelligent algorithm of the mechanical device of computer control some people exploitation
To reach the platform that control machinery plant automation completes certain intelligent work.Existing mechanical device can not be detached from the control of people
System goes to complete a certain item task, it is necessary to the control in some stage is completed by people.The prior art, people can only be by by outsides
Equipment send instructions to mechanical equipment, and control machinery equipment cannot be gone by the physiological signal collection of people itself, Bu Nengyong
My physical signs state goes control machinery equipment now.The artificial intelligence of the people and machine that cannot really do.
At present, the Emotion identification of psychological field, the interference from human factor of Human Factors Engineering Field, ergonomics
Design analysis etc. is the problem is that the acquisition of effective physiological data and objective physiological data analysis cannot be carried out.And physiology
The solution of some countermeasures of problems after data analysis.And the artificial intelligence field prior art can only be by being set outside human hand held
It is standby to remove control machinery device, and the physiological signal for being unable to employment removes control machinery device.
Therefore, needing exist for a physical signs goes measurement to test and analyze some problems that these are illustrated by objective factor.
In the case that human psychological is nervous or excited, the sweat gland of some sensitive skin parts can secrete a large amount of sweat, and
This process is not again that non-autonomic nerve controls, and the temperature of the more more skins at this time of secretion degree of sweat has corresponding change
Change, therefore skin temperature is to weigh a very crucial index of an individual psychology health status or emotional state, many moods
Variation is all embodied in the variation of skin temperature, so the measurement of human body skin temperature is in psychological field, ergonomics field, people
Occupy highly important status in work smart field.And there is no a kind of products measuring skin temperature at present.And most commonly body
Temperature measuring instrument.Conventional mercury formula clinical thermometer and electronic thermometer be by oral cavity, armpit, rectum etc. be in direct contact body surface come
Measure human body temperature, the body temperature at this moment measured.Body temperature is constant, and body temperature can reach flat by the regulatory function of people itself
Weighing apparatus.But these are not that we want the index of the related psychological field measured, and psychology index has instantaneity, interval
Property, conditions of the current stage, have spent this period, physical signs can tend towards stability.Psychology index is mainly studied when stimulation occurs
Some of some human bodies are corresponding to be changed.The meaning of psychology skin temperature index is the variation of tested skin temperature with psychological shape
The influence of state or mood correlative factor and become.
The non-contact temperature measuring device for also having measuring temperature in a non-contact manner on the market at present, is based on black body radiation
Philosophy realizes thermometric, also known as Radiation Temperature Measurement Instrument.Existing contactless Radiation Temperature Measurement Instrument mostly uses the shape of temperature-measuring gun
Formula measures forehead temperature, and what is actually measured is body temperature, can not be used to automatically and quickly measure the change of tested skin temperature
Change, not the reference significance of psychological measurement, and the temperature-measuring results of this mode are easy by thermometric angle and measure visual field
It influences, can not accomplish that single point temperature measures.When the angle changing rate of the temperature measuring unit of temperature-measuring gun and object under test is big, connect
The radiation energy received can substantially reduce, and temperature-measuring results can become insincere；In addition, when object under test is smaller than measurement visual field, the back of the body
Scape radiation energy can largely enter the temperature measurement module of temperature measurer, interfere thermometry readings, and temperature measurer thermometric is i.e. by being to be measured at this time
The weighted average of object and its ambient temperature, causes measurement error.In addition, tested skin skin temperature is easy by the temperature shadow such as environment
It rings, if only judging the psychological condition and mood of subject with the parameter, is sometimes prone to generate bigger error.
It is then desired to which a kind of do not influenced and ensure to measure visual field and be less than to be detected skin, can realize skin Wen Dan by thermometric angle
The skin physiology instrument for measuring index that point measures.
