Embodiment 1

[0050] figure 1 The physiological state transition of the human body described in the present invention includes transition from a normal life and work state to a micro-sleep state, from a micro-sleep state to a sleep state, and from a micro-sleep state or a sleep state to a normal life and work state.

[0051] A method for detecting the transition of the physiological state of the human body in the present invention comprises the following steps: initializing parameters, collecting data of human body resistance, analyzing the data of human body resistance and outputting the transition of the physiological state of the human body.

[0052] figure 2 It is a flow chart of analyzing human body resistance data in the method of the present invention, including preprocessing, taking logarithms, window processing, comparing logarithmic differences, calculating convergence values, and analyzing physiological state transitions. During the test, the tester’s skin resistance data is fi...

Embodiment 2

[0087] Figure 6 is the variation of the MeanDiff value in a test instance. According to the physical condition judgment rule, it is judged that the tester has a relatively sensitive constitution, so the threshold MeanDiff is used 敏感,微睡眠 and MeanDiff敏感,睡眠 To judge the change of the tester's physiological state.

[0088] Judging that the MeanDiff value is less than or equal to MeanDiff 敏感,微睡眠 The situation is that the human body changes from a normal life and work state to a micro-sleep state. Figure 7 For the detection situation of the micro-sleep state in a test example, the abscissa in the figure represents time; The ordinate is 1 and represents MeanDiff numerical value is less than or equal to 0.0006 (being MeanDiff 敏感,微睡眠 value), that is, the micro-sleep state or the sleep state; the ordinate is 0 to represent the situation where the MeanDiff value is greater than 0.0006 (that is, the MeanDiff 敏感,微睡眠 value), that is, the normal life and work status.

Abstract

Disclosed are a method and a system for detecting a human physiological status transition. By means of an adaptive algorithm, different physiological status transition analysis parameters are set up according to different physique conditions of users, and accordingly, the problem of individual differences can be overcome to reflect the physiological status transition of a subject more accurately.

Description

technical field [0001] The invention relates to a method and system for detecting the transition of human physiological state. Background technique [0002] When the human body receives external stimuli or internal emotional fluctuations, the sympathetic nervous system will change, and the sympathetic nerves will lead to changes in the activity of sweat glands, which will eventually lead to changes in skin resistance. Generally speaking, when external stimuli or internal emotional fluctuations are greater, the sympathetic nerves are more active, the secretion of sweat glands is enhanced, the electrical conductivity of the skin is enhanced, and the skin resistance of the human body becomes smaller; on the contrary, in a calm state, the sympathetic nerves are in a state of inhibition, and the sweat glands are active. Weaken, the electrical conductivity of the skin is weakened, and the resistance of the human skin becomes larger. Using this principle, we can judge the changes ...
