S101, the pulse signal for obtaining person under test.
In the embodiment of the present invention, pulse signal is the signal of the tangible arteriopalmus arrived of body surface.Human recycle system by
Heart, blood vessel, blood are constituted, and are responsible for the transport of human body oxygen, carbon dioxide, nutrient and waste.Blood via heart a left side
Ventricular contraction and extrude inflow sustainer, systemic arterial is delivered to immediately.Connective tissue and muscle institute of the artery for high resilience
Form pipeline.When a large amount of blood enter artery arterial pressure change will be made to expand caliber greatly, in the shallower place's artery of body surface
Experience this expansion, i.e., so-called pulse.In the embodiment of the present invention, it can be analyzed from pulse signal and acquire heart rate data
And heart rate variability data, wherein, heart rate refers to the number of times of heart bounce per minute；Heart rate variability data are generally used for analyzing the heart
Rate variability (heart rate variability, HRV).HRV HRV is reflection autonomic nerves system activity and fixed
Amount assesses cardiac sympathetic nerve and vagal tone and its balance, so as to judge its state of an illness to angiocardiopathy and pre-
It is anti-, it may be possible to predict a valuable index of sudden cardiac death and arrhythmia cordis sexual behavior part.Fatefulue arrhythmia cordis with
Excitability increase, the reduction of vagal excitability of sympathetic nerve are relevant, and the quantization of Autonomic nervous system activity can pass through
The degree shows of changes in heart rate come out, and HRV HRV represents such a quantization mapping.It is i.e. continuous normal by measurement
The variability that the phase changes between maxima and minima reflects changes in heart rate degree, rule, so as to judge it to painstaking effort
The influence of pipe activity.HRV HRV is reduced to sympathetic tone and increased, it is possible to decrease ventricular fibrillation threshholdses, belongs to unfavorable factor；Heart rate
Variability HRV rises are increased for parasympathetic tone, improve ventricular fibrillation threshholdses, belong to protection factor.
In the embodiment of the present invention, when needing to detect the current fatigue state of person under test, person under test can be obtained current
Pulse signal；When needing to detect the fatigue state in person under test's nearly a period of time, then person under test can be obtained in advance setting
Period in pulse signal.
S102, the acceleration signal for obtaining person under test.
In the embodiment of the present invention, obtaining the acceleration signal of person under test mainly includes obtaining person under test under motion state
Acceleration signal.Wherein, acceleration (Acceleration) is velocity variable with occurring the ratio of time used in this change,
It is to describe the physical quantity that object speed changes speed, is generally represented with a, unit is m/s2.Acceleration is vector, and its direction is
The direction of object speed change (amount), it is identical with the direction of bonding force.Wherein, acceleration signal is used for the motion for characterizing person under test
The signal of state.
In the embodiment of the present invention, by the acceleration signal of the person under test to getting analyze person under test type of sports,
Move the movable information such as duration and exercise intensity.
S103, judge according to pulse signal and acceleration signal whether person under test is in fatigue state.
In the embodiment of the present invention, fatigue state can include the fatigue state of sports fatigue and the tired shape of mental fatigue
State.Wherein, mental fatigue refers to as various non-absent minded caused by reason, reagencies decline, the alertness of being short of physical strength
Reduction.Tired shape during typical mental fatigue such as automobile (train, aircraft, steamer ...) driver's long-duration driving
State.Sports fatigue is due to that energy expenditure, muscle strength decline and excitability forfeiture three-dimensional relationship in motion process change
Caused by becoming.Under comprehensive sexual factor effect, during intracellular energy consumption and excitation of muscle forfeiture, there is one drastically
The mutation peak of decline, excitability is collapsed suddenly, is changed with the calamity saved the further decline of energy reserve and produced, simultaneously
Along with the unexpected decline of muscle strength and power output, fatigue is shown as.
, can be with when the acceleration signal of the pulse signal and person under test that get person under test in the embodiment of the present invention
Judge whether person under test is in fatigue state according to the acceleration signal of the pulse signal of person under test and person under test.
If S104, person under test are in fatigue state, according to the pulse signal, acceleration signal and fatigue prestored
The mapping relations of Status Level determine the fatigue state rank of person under test.
In the embodiment of the present invention, pulse signal, acceleration signal and fatigue state rank can be prestored in terminal
Mapping relations.The mapping relations of the pulse signal prestored, acceleration signal and fatigue state rank can be root
Obtained according to many experiments detection, and reply different age group has different mapping relations, different sexes has different mappings to close
System；Can also be according to the mapping relations obtained by person under test's health states in itself and physiological characteristic information.
For example, when above-mentioned person under test be the male of 18 years old at an age, then terminal prestore pulse signal,
The mapping relations of acceleration signal and fatigue state rank are also all consistent according to belonging to this age bracket, and are all logical
Cross the mapping relations that pulse signal of the detection male under different acceleration signals is obtained.Wherein, above-mentioned age bracket can be
16~25 years old or 16~20, the span of age bracket can be set as needed, the present invention is not construed as limiting.
In the embodiment of the present invention, according to reflecting obtained by person under test's health states in itself and physiological characteristic information
Relation is penetrated, then the prolonged corresponding fatigue of pulse signal under different acceleration signals of the person under test should be recorded in terminal
Status Level.And recording the prolonged corresponding fatigue state rank of pulse signal under different acceleration of the person under test
When, it should be closely connected with the health of person under test.
In Fig. 1, terminal can first obtain the pulse signal of person under test；The acceleration signal of person under test is obtained again；And root
Judge whether person under test is in fatigue state according to pulse signal and acceleration signal；If person under test is in fatigue state,
The tired shape of person under test is determined according to the mapping relations of the pulse signal prestored, acceleration signal and fatigue state rank
State rank.Implement the embodiment of the present invention, terminal can be combined progress judgement person under test according to pulse signal and acceleration signal
Whether fatigue state is in, and meeting is according to the mapping of pulse signal, acceleration signal and the fatigue state rank prestored
