Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
Before describing technical solution of the present invention, need to carry out sleep stage following explanation.Sleep medicine will sleep
It is divided into non-rapid eye movement phase and the sleep of rapid eye movement phase.Sleep medicine association of the U.S. (The American Academy of
Sleep Medicine, AASM) the non-rapid eye movement phase, which sleeps, is further divided into three different phases: N1, N2, N3.It is corresponding strong
The adult of health, a sleep cycle typically last for 90~100 minutes, with 3 stages of non-rapid eye movement phase, then
It is rapid eye movement phase (REM).
Wherein, the first stage (N1) is most shallow shortest stage (1~7 minute) of sleeping, and indicate from awake (W) to
The transformation of sleep.It is second stage (N2) after first stage (N1), is usually lasting 10~25 minutes, this stage body reaches
To the state loosened completely, it is prepared to enter into deeper sleep.After second stage (N2), a normal adults can enter
Phase III (N3) typically lasts for 20~40 minutes, this is that the final stage of non-rapid eye movement is also referred to as the sound sleep phase, at this
Stage human body carries out most reparation and reproduction operation.In the phase III (N3) after the stage, normal adults can return to shallower
The non-rapid eye movement phase, continue 5~enter rapid eye movement stage (REM) after ten minutes.The characteristics of rapid eye movement phase sleeps is big
Brain is active, and memory consolidation occurs at this time.The rapid eye movement phase occupies 20~25% in the whole sleep of normal adults.Health at
Sleep stage before Nian Renhui is periodically repeated changes.Since each stage corresponds to vital physiological function,
Therefore sleep stage analysis is vital for evaluation sleep quality.
Heretofore described sleep stage can at least be divided into 2 kinds of states, lucid interval and sleep period；It can also will sleep
Phase is further divided into rapid eye movement phase and non-rapid eye movement phase；The non-rapid eye movement phase, which can also be further divided into, shallowly sleeps phase and sound sleep
Phase.The point-score of sleep stage can not also include the rapid eye movement phase, be only divided into sleep period and shallowly sleeping phase and sound sleep phase.
Fig. 1 is the method flow diagram of determining sleep stage of the present invention.
As shown in Figure 1, a kind of method of determining sleep stage, includes the following steps:
According to the heart rate feature of user's current slot, the first sleep stage locating for user's current slot is obtained；
Whether the variation relation of the second sleep stage and the first sleep stage that judge previous time period meets default sleep
Phase change rule；
The feelings of default sleep stage changing rule are not met in the variation relation of the second sleep stage and the first sleep stage
Under condition, according to the respiratory characteristic of user's current slot, third sleep stage locating for user's current slot is obtained；
Compare third sleep stage and whether the first sleep stage is identical, and user's current time is determined according to comparison result
Sleep stage locating for section.
According to pertinent literature Heart rate variability, sleep and sleep disorders (Phyllis
K.Stein, 2012) record, the heartbeat each time of heart rate are all being adjusted, this is by sympathetic nerve and parasympathetic
The collective effect of nervous system.So the variation (i.e. heart rate variability) of heart rate can provide body self-discipline in measurement a period of time
Neururgic information.Sleep is to measure parasympathetic functions relatively good more period, therefore, in a particular embodiment, from
Available corresponding heart rate sleep characteristics parameter in heart rate sleep characteristics signal, it may be assumed that heart rate variability parameter, comprising: heart rate
Time domain variability parameter and heart rate frequency domain variability parameter.And heart rate frequency domain variability parameter includes: high band energy parameter HF
With low-frequency range energy parameter LF.LF reacts the heart rate rhythm in 2.5~9 underrange per minute, and HF reacts 9~24 models per minute
Enclose interior heart rate rhythm.LF is to be controlled by sympathetic and parasympathetic nerve, and HF is only to be controlled by parasympathetic nerve, and LF/HF is logical
It is usually used in evaluating the variation of autonomic nerve in each sleep stage.It can decline shallowly sleeping phase and sound sleep phase heart rate variability, and fast
The fast eye movement phase, heart rate variability, which is greater than, shallowly sleeps phase and sound sleep phase, while rapid eye movement phase heart rate is higher than the awakening phase.In non-rapid eye
Dynamic phase sleep stage, the ratio of HF/LF gradually rise, and in the rapid eye movement phase, HF/LF ratio can then significantly reduce.
Other than it can determine sleep stage by heart rate variability, pertinent literature Heart period
Variability in sleep (B.V.Vaughn, 1995) also describe control of the autobnomic nervous system on cardiac cycle and
Sleep stage is closely connected, and on different sleep stage cardiac cycle autonomic nerve control determination it is variant, therefore week aroused in interest
Phase can also be used as the reliable basis of determining sleep stage.
Heretofore described heart rate feature includes but are not limited to above-mentioned heart rate variability and cardiac cycle, the present invention
Used in heart rate feature compared with body moves feature, interpersonal existing otherness is smaller, can be used as judgement sleep rank
Therefore the reliable basis of section obtains the first sleep stage of current slot, reliability according to heart rate feature in the present invention
Height, judging result are accurate.
In a specific embodiment of the present invention, according to the heart rate feature of user's current slot, user's current time is obtained

First sleep stage locating for user's current slot.
In the present invention, do not slept using the first sleep stage directly obtained as heart rate feature as locating for current slot
The final judging result in dormancy stage, but default sleep stage changing rule is combined to carry out secondary judgement, in order to make judging result
More accuracy, the first sleep stage generally obtained according to current slot according to heart rate feature with next to current slot
The second sleep stage of previous time period judged that wherein sleep stage locating for initial time section can be directly by user
Customized or heart rate feature according to initial time section determines, wherein the case where being customized by the user includes when user just lies
When in bed, the sleep stage for defining initial time section is the awakening phase.
Heretofore described default sleep stage changing rule is according to the sleep stage variation being likely to occur in sleep
It obtains, needs to meet the objective law of things variation, such as default sleep stage changing rule are as follows: the awakening phase-shallowly sleeps the phase-sound sleep
Phase-shallowly sleeps the phase-and the rapid eye movement phase-shallowly sleeps the phase-and the sound sleep phase-shallowly sleeps the phase-rapid eye movement the phase-..., for example, it is assumed that the first sleep rank
Section is the sound sleep phase, and the second sleep stage is the rapid eye movement phase, then the variation relation of the first sleep stage and the second sleep stage does not have
It falls in default sleep stage changing rule, does not meet objective law；Assuming that the first sleep stage is the sound sleep phase, second sleeps
The dormancy stage is shallowly to sleep the phase, then the variation relation of the first sleep stage and the second sleep stage drops into default sleep stage variation rule
In rule, meet objective law.
Judging that the variation relation of the second sleep stage and the first sleep stage meets default sleep stage and become in the present invention
In the case where law, the first sleep stage can be determined directly as sleep stage locating for user's current slot.?
In the case that the variation relation of two sleep stages and the first sleep stage does not meet default sleep stage changing rule, need to introduce
First auxiliary judgment parameter, i.e. respiratory characteristic obtain user's current slot institute according to the respiratory characteristic of user's current slot
The third sleep stage at place.

Sleep characteristics parameter include: respiratory rate, the energy of different frequency bands, the self-similarity of breathing, breathing rhythmicity, and breathing
Amplitude (such as breathe depth and breathing volume).In the rapid eye movement phase, depth of respiration is more regular, and moisture
Amount, minute ventilation and gettering rate will be significant relatively low than the non-rapid eye movement phase.Breathe sleep characteristics signal on envelope and
Area respectively corresponds the depth and volume of breathing.Effect of the variability of the depth of breathing when identifying the sound sleep phase is preferable, and exhales
Effect of the systematicness of the depth of suction when distinguishing awakening phase and sleep period is preferable, and the volume of breathing is when detecting the rapid eye movement phase
Effect it is preferable.Therefore respiratory characteristic can be used as the reliable basis of determining sleep stage.
