In step S101, obtain the skin conductivity rate in the setting-up time cycle by skin electric conductivity sensor.
Skin electric conductivity (or referred to as galvanic skin response GSR, galvanic skin response EDR, psychogalvanic PGR, galvanic skin response, skin conductivity level) is the physical signs of the reflection emotion changes of application early.Research shows, the threat that perception or think has influence on existence can impel a large amount of reductions of parasympathetic activity, and the orthosympathetic activity of corresponding stimulation.Sympathetic nerve and parasympathetic nervous are under the jurisdiction of in autonomic nervous system, in the time that human pressure is excessive, human body is under the larger state of relative load, neural tight, the raising that people's stress ability can respond, this has corresponding variation to antagonism nerve sympathetic nerve and parasympathetic nervous, and the excessive orthosympathetic efficiency of controlling stress ability that causes of human pressure is amplified, and parasympathetic activity is faced weakening of pressure and can be occurred with the enhancing of sympathetic nervous system activity simultaneously.This sign phenomenon can obtain reaction clearly on skin electric conductivity.Many psychological phenomenons and skin electricity level have substantial connection, and emotional response can cause the sharply variation of skin electricity level.It is according to moisture, the sweat of skin.Sweat is by sympathetic nervous system control, so skin conductivity can be used as the human body sign of psychology or physiological stimulation.Therefore, if autonomic sympathetic nerve branch fever, then sweat gland activity also will increase, thereby increase skin conductivity.The theory of the emotion control of skin electric conductivity is well attached in popular life.
In the present embodiment, in the described setting-up time cycle, comprise: the moon, week, day, working time section.For example, carry out the setting in cycle in sample time according to the life of target sample or working method, some working in morning, have a rest evening, the sample time that can calculating pressure grade is determined 12 hours by day, if the user of work in evening can be controlled at evening by the sample time, user can adjust according to the daily life system of oneself.Carry out the selected of sample time according to the real life of target sample, increased the effectiveness of sample, meet user's individual demand.
