Using in above-mentioned sleep monitor 20 detection user's sleep procedure, the specific detection method is as follows for the dynamic variation of body:
Sleep monitor 20 is placed in application environment described in Fig. 1, baroceptor 22 acquires the air pressure in warming space 14, and
Collected data are transmitted to processor 23, processor 23 obtains the barometric information, and judges user according to the barometric information
Whether generating body is dynamic in sleep procedure.
Fig. 4 be it is provided by the embodiment of the utility model, can be executed by above-mentioned processor, the body for detecting user 11 is dynamic
The sleep body of number moves monitoring method.As shown in figure 4, this method comprises:
Step 41 acquires the barometric information to keep warm in space；Barometric information is arranged according to the sequence of acquisition time,
Form barometric information sequence.
The acquisition of air pressure can be carried out in the utility model embodiment using baroceptor, air pressure sensing implement body can be with
It is acquired with any suitable sample frequency, for example, continuous acquisition keeps warm in space in the form of a barometric information per second
Barometric information, processor obtains the barometric information and obtains barometric information sequence.
Barometric information sequence in this implementation is ranked up according to the sequence of acquisition time, the barometric information sequence,
It can react in special time period, the air pressure change situation to keep warm in space, processor obtains the barometric information can be to the gas
Data are pressed to carry out the operation of next step.
Step 42 determines whether barometric information sequence meets default body and move condition.If so, thening follow the steps 43；If it is not, then
Execute step 44.
It will be appreciated by persons skilled in the art that in the case where 11 generating body of user is dynamic, due to the change of body position
Change, it will usually cause outside air to enter in warming space, enables air and outside air in warming space that heat occurs and exchange,
So that the variation of the air pressure Development pattern in warming space.
It therefore, can be by judging whether barometric information sequence includes such regular change information, to judge user
Whether generating body is moved and further realizes the counting moved to body.Correspondingly, condition can be moved by above-mentioned default body come table
Show the regularity variation of above-mentioned air pressure.Wherein, presetting the dynamic condition of body specifically can be by those skilled in the art according to the actual situation
It determines.
Step 43 determines that generating body is dynamic in warming space.
Meet above-mentioned default body move condition when, can determine that the barometric information sequence contains the change of the regularity
Change, so that it is determined that user 11 is in warming space, a body motion occurs.And further by the barometric information sequence, to user 11
Body dynamic counted.
Step 44 determines that non-generating body is dynamic in warming space.
Be unsatisfactory for above-mentioned default body move condition when, can determine the barometric information sequence do not include the regularity change
Change, so that it is determined that user 11 is in warming space, there is no bodies to move.
The utility model embodiment moves condition by judging whether the barometric information sequence in warming space meets default body,
To determine user, whether generating body is dynamic in sleep procedure.On the one hand obtain more complicated than switching signal is detected using baroceptor
More body movement signals realizes bigger application value.On the other hand, using the change of the air pressure to keep warm in space in sleep procedure
Change than using the movement of user's head in sleep procedure to drive the variation of acceleration that determine that the body of user moves more intuitive and conveniently.
As described above, when user occurs to act such as turning in warming space, gas that baroceptor detects
Press the variation of data meeting Development pattern.For example, during user turns over, the hot-air and cool exterior air hair that keep warm in space
Raw strong exchange can cause the variation of air pressure due to air-flow itself, so that the barometric information that baroceptor detects is presented
What height changed repeatedly, in another example, after user completes turn movement, the air to keep warm in space is gradually added by the body temperature by user
Heat, so that the barometric information that baroceptor detects is on a declining curve.It is user in bedding 13 referring specifically to Fig. 8, Fig. 8
A kind of air pressure when a body motion occurs changes with time relational graph.
Regularity variation, can use the barometric information variation tendency of barometric information within a certain period of time as Fig. 8
(that is, atmospheric pressure state) indicates.Therefore, above-mentioned two situations can be indicated by the variation of atmospheric pressure state.In the present embodiment
In, i.e., above situation is specifically defined as stable state and shake state two states.It is such, it can be reflected according to barometric information
Atmospheric pressure state variation, determining user, whether generating body is dynamic, method is specifically determined, as shown in figure 5, step 42 is specifically wrapped
It includes:
Step 421, according to barometric information sequence, determine the variation of atmospheric pressure state.
In the utility model embodiment, the variation of atmospheric pressure state includes stable state and shake state.Stable state has for air pressure
The state of slow downward trend, shake state are the state that air pressure occurs that height changes repeatedly, respectively with above-mentioned two situations pair
It answers.In barometric information sequence, it is determined that above two state can determine the variation of atmospheric pressure state.In such as above-mentioned Fig. 8, Fig. 8
Be labelled with body of generation it is dynamic when, the state of air pressure becomes dither state from stable state when restoring again to stable state, air pressure
The variation tendency of data.
Step 422, in the variation of atmospheric pressure state, to meet atmospheric pressure state be first shake state by stable state variation, then by shake state
When recovery to stable state, determine that generating body is dynamic in warming space.
It is dynamic that primary complete body is defined in the present embodiment, barometric wave shape is as shown in figure 8, need by stable state, to shake state
Restore again to stable state.This is because: Fig. 9 is if can refer to Fig. 9 from the point of view of above-mentioned Fig. 8 is described as a longer period
In the longer period, the body of user moves changing rule.From fig. 9, it can be seen that needing that once complete body is dynamic is limited to by user
Front and back will have stable state, can exclude user in this way and just fall asleep what generation barometric information when just getting up with user was shaken
Above two scene is not counted in the dynamic number of body to facilitate by scene.In addition, the dynamic monitoring method of sleep body provided in this embodiment is strong
What is adjusted is that sleep body is dynamic, is not belonging in this computer capacity so body when falling asleep and is awake is dynamic.
It should be noted that in Fig. 9, stable state after the 4th time body the is dynamic stable state dynamic compared to preceding body three times, when
Between it is longer, this is because stable state and shake state time span be it is uncertain, this is because the posture of user's sleep and dynamic
It makes decision, the judgment method that can be provided through this embodiment is come adaptive.
Barometric information is at least identified as two states by the utility model embodiment: stable state and shake state, without
Waveform is formed by according to acquisition time to barometric information and carries out detail analysis, only need to can determine by the variation of atmospheric pressure state
Whether generating body is dynamic.Further, stable state is restored to be defined as using to stable state again by the utility model embodiment to shake state
The adjustment of the primary sleep posture at family, in the process, no matter user has turned body several times, and trick has been moved how many times, has all only been considered as
The adjustment of primary sleep posture, and think a body only has occurred dynamic, this mode can be by the sleep movementization of user is numerous
Letter makes the technical program simply preferably go, as a result accurately.
In some embodiments, it can determine whether the variation of atmospheric pressure state meets by a series of logic steps
It is shake state, then the mode by trembling Dynamic- Recovery to stable state by stable state variation.In order to which the logic of following introductions is described in detail
Atmospheric pressure state by stable state variation is first shake state in the present embodiment by judgment method, then by trembling Dynamic- Recovery to stable state institute
The detection cycle of experience adds up, and is calculated as an individual dynamic counting period.The body is dynamic to count the period for characterizing user's generation one
Secondary body moves duration experienced.
Specifically, the logic step may include:
Firstly, determining the amplitude of variation of barometric information in detection cycle.
" barometric information in detection cycle " of the utility model meaning indicates several collected gas in certain time period
Data are pressed, for example, " barometric information in detection cycle " then indicates collected several in 5 seconds when every five seconds is a detection cycle
A barometric information；I.e. " amplitude of variation for determining barometric information in detection cycle " indicates to determine collected barometric information in 5 seconds
Amplitude of variation.The utility model carries out the absolute value of the difference between adjacent two barometric information in each detection cycle
It is cumulative to obtain the amplitude of variation in each detection cycle.
Here drawing amplitude of variation is because the amplitude of variation of air pressure can more than or equal to amplitude threshold in detection cycle
As the judgment basis whether shaken in the current detection period, therefore, by current detection period definition in the present embodiment
The period is judged to tremble dynamic origins.
Specifically, the amplitude of variation of air pressure can be by will test the absolute value of the difference in the period between adjacent two barometric information
It is added up to obtain, and at the end of each detection cycle, amplitude of variation is reset into New count of laying equal stress on.
Here can be determined with amplitude of variation whether there is within a certain period (that is: tremble dynamic origins and judge the period)
Trembling dynamic starting point is that a body motion occurs in bedding 13 because of user 11.After body is dynamic, 13 inner air and outer air of bedding will occur
Strong exchange, and air-flow itself will cause the variation of air pressure, so sensor can detect strongly when body is dynamic
Air pressure change, as shown in Figure 10.
Specifically, table 1 is please referred to, table 1 is that a kind of barometric information variation provided by the embodiment of the utility model is lower, air pressure
The specific calculation of amplitude of variation is illustrated:
Table 1
Secondly, judge from a upper individual it is dynamic count the period tremble dynamic end-point, it is tired to trembling before dynamic origins judges the period
Whether the variability index added is greater than index threshold.Here drawing variability index is because meeting accumulative variability index and being greater than finger
Number threshold values, it may be determined that current gas pressure generally in downward trend, have the generation of stable state.
Wherein, variability index is calculated by following formula:
Wherein, f (x) is variability index, x1For the first barometric information of acquisition time, x2For the posterior air pressure of acquisition time
Data, T are preset constant.
The reason of calculating in this way is: standard atmospheric pressure is 1013hpa, and height above sea level is higher, and air pressure is lower, it is assumed that locating for user
Height above sea level air pressure is 1000hpa, and baroceptor resolution ratio is 0.01hpa, then the detected value actually obtained is 1000.00hpa.I.e.
Baroceptor is very sensitive to air pressure change, can detect the slight change of air pressure.Further, baroceptor is in addition to dividing
Resolution, there are one precision index, for example air pressure is completely constant, this air pressure of baroceptor repeated measurement, resulting measurement
Value is also what is changed repeatedly, and only from the point of view of the long period, as shown in figure 11, the average value of the measured value of baroceptor is
Close to tested atmospheric pressure value.
Therefore, it is caused to get the entire lowering trend of air pressure and evade baroceptor itself precision
Data dithering, introduce above-mentioned variability index, wherein above-mentioned data are consecutive variations, until shake occur when be likely to by
Pause is counted or is reset.When shaking state generation, variability index suspends counting first, and calculates cumulative variability index
Value, when cumulative variability index is greater than index threshold, the judgement for continuing following step (trembles dynamic origins and judges that the period goes out
Whether existing number is greater than or equal to the first frequency threshold value, it may be assumed that finds the body dynamic counting period trembles dynamic end-point).
It is greater than or equal to the first frequency threshold value if meeting and trembling the number that dynamic origins judge that the period occurs, then it is assumed that occur
Body is dynamic.At this time variability index can be zeroed out after the dwell processing (such as in table 3 and table 4 in variability index pause for 197
Later, it is zeroed out processing)
If being unsatisfactory for trembling the number that dynamic origins judge that the period occurs is greater than or equal to the first frequency threshold value, then it is assumed that do not have
There is generating body dynamic.Variability index can carry out the processing of recovery again after the dwell at this time.
It should be noted that and since the resolution ratio of the data of baroceptor measurement is 0.01hpa, following table
In data can be understood as the resolution ratio of 1.00pha if being only left 1hpa.In addition, when cumulative in the present embodiment
When variability index afterwards is 0, it is no longer kept to negative at this time, i.e. variability index declines air pressure more sensitive, is with the direction increased
It is main.Specifically, table 2 is please referred to, table 2 is that a kind of barometric information variation provided by the embodiment of the utility model is lower, variability index
Specific calculation citing:
Table 2
The difference between adjacent two barometric information be calculated by above-mentioned table 2 are as follows:
Barometric information 1000.1 when beginning, variability index 0, second barometric information are 1000.2, calculate difference is
1000.1-1000.2=-0.1 is negative, and variability index subtracts 1, is minimum value since current variability index has been 0, it may be determined that
It is invalid to subtract 1, and keeping variability index is 0.Third number 1000.1 calculates 1000.2-1000.1=0.1, is positive number, variability index
Add 1, so variability index becomes 1, data later add up in the manner described above.
It should be noted that, although above-mentioned data overall trend is decline, but due to the precision problem of sensor, sometimes
(such as the 6th barometric information) can up be shaken by waiting data, cause variability index to decline, but after a period of time, variability index meeting
Restore to increase.
Therefore, by the index threshold of setting, sensing data can be significantly stronger than with the entire lowering trend of characterize data
The shake of itself proves the generation for having stable state.
It should be noted that lacked the metastable environment in bedding if sensor is an exposure to outside bedding,
Due to there is the influence of air-flow and temperature and sensor itself precision, although data can shake repeatedly, it is hardly formed strong
Downward trend, it may be assumed that the variability index being exposed at outside bedding does not exceed the threshold value of setting, and it is clear also to trigger variability index
Zero, it realizes anti-interference.
In conclusion setting 5hPa for the amplitude of variation of air pressure, index threshold is set as 100 in table 1, it may be assumed that shake inspection
Measured value is more than amplitude threshold 5hPa, then it is assumed that and shake occurs, and when shaking generation, suspends the counting of above-mentioned variability index,
And check the value of variability index, as shown in table 3, variability index when pause is 197, is greater than index threshold 100, indicates shake
There is stable state before state, the starting point that body moves the time has been recorded, it may be assumed that this is trembled dynamic origins and judges that the period rises for shake state
Point, atmospheric pressure state are become shaking state from stable state.
It can determine that trembling dynamic starting point determines: atmospheric pressure state by the amplitude of variation and accumulative variability index of air pressure
Become shaking state from stable state.
Finally, after determining and trembling dynamic origins, when trembling number that dynamic origins judges that the period occurs more than or equal to the
When one frequency threshold value, be determined as the ontology dynamic counting period trembles dynamic end-point, and institute's atmospheric pressure state is by trembling Dynamic- Recovery to stable state.
Above by trembling, the number that dynamic origins judge that the period occurs is true more than or equal to such mode of the first frequency threshold value
Surely the reason of trembling dynamic terminal is: when trembling dynamic starting point, the air pressure to keep warm in space by a rapid increase process,
So that air pressure rises, change repeatedly trembling dynamic pilot process air pressure in height, and in the pilot process, will not occur again
Amplitude of variation is greater than or equal to amplitude threshold.In addition, when trembling dynamic terminal, it is dynamic for a body occurs.At this time, it is also necessary to will
The variability index suspended before is zeroed out processing and lays equal stress on New count to carry out the judgement of the variation of atmospheric pressure state next time.?
In the present embodiment, which can be determined by experiment by those skilled in the art or be arranged according to the actual situation.
Referring specifically to table 3 and table 4, table 3 and table 4 are that a kind of first frequency threshold value provided by the embodiment of the utility model is
When 3, also, the amplitude of variation of barometric information satisfaction is less than the barometric information citing when number that amplitude threshold occurs is 3 times:
Table 3
Table 4
Wherein, 3 times or more shaking detection values are below amplitude threshold 5hPa, determine the dynamic shake state for counting the period of ontology
Terminal, atmospheric pressure state is by trembling Dynamic- Recovery to stable state.
The utility model determines that gas strengthens the variation of state using the amplitude of variation and variability index of barometric information, and final
According to the variation of determining User Status, to determine that whether final user's generating body be dynamic.Such judgment method, it is not necessary to consider air pressure
The absolute value of data reduces influence of the environmental factor to measurement result, and the requirement to sensor accuracy.This judgement side
Method is detected the body movement signal more much more complex than switching signal using baroceptor, realizes bigger application value.
It should be understood that in the present embodiment, although the version when atmospheric pressure state is first to tremble by stable state variation
Dynamically, then by trembling Dynamic- Recovery to stable state, it is determined that the version of atmospheric pressure state meets default body and moves condition, determines user
It is dynamic that a body occurs, but is not first determining stable state, then determining shake state during actually determining that user's body is dynamic, into
And determine stable state, but directly first search to be switched to by stable state and tremble dynamic first switching point, when finding the first switching point
Later, conversion lookup is switched to the second switching point of stable state by shake state, when finding the second switching point, then illustrates atmospheric pressure state
Version to meet first be shake state by stable state variation, then by trembling Dynamic- Recovery to stable state, as shown in fig. 6, this method
It specifically includes:
Step 601 obtains barometric information sequence；
Air pressure sensing implement body can be acquired with any suitable sample frequency, for example, with an air pressure number per second
According to the barometric information that keeps warm in space of form continuous acquisition, processor obtains the barometric information and obtains barometric information sequence.
Barometric information sequence is the data sequence sequentially formed by collected barometric information of multiple and different moment, the air pressure
Data sequence can react in special time period, the air pressure change situation in the space that keeps warm.
Step 602, the amplitude of variation for calculating air pressure, cumulative variability index.
The calculation of the above-mentioned cumulative variability index to amplitude of variation is equally applicable in the present embodiment, no longer superfluous
It states.
Step 603 judges whether amplitude of variation is greater than or equal to amplitude threshold, if executing step 604, if it is not, resetting
Amplitude of variation, and execute step 602；
Step 604 judges whether variability index is greater than index threshold, if executing step 605 (can determine at this time be to tremble
Dynamic starting point), if it is not, executing step 602；
Herein it should be explained that: since stable state is that air pressure has the state of slow downward trend, then stable state when
Between in section, the difference between every two adjacent barometric information is positive, and in the period of stable state, variability index be will increase.
In step 604, if variability index is greater than index threshold, then it is assumed that tremble a period of time before dynamic starting point it
Interior, air pressure has downward trend, that is, determines and stable state has occurred before shake state.
The benefit that stable state whether occurs before shake state is determined in the way of such is: the influence of extraneous factor is avoided,
Or the failure of baroceptor, so that the barometric information that baroceptor measures drifts about, the change for causing sensor to measure
Change amplitude is greater than amplitude threshold, and judges the starting point that step 603 is shake by accident.
The size of step 605, the amplitude of variation for comparing air pressure and preset amplitude threshold；
Step 606, the amplitude of variation for recording air pressure are less than the frequency of occurrence of amplitude threshold；
Step 607 judges that the amplitude of variation of air pressure is less than whether the number that amplitude threshold occurs is greater than or equal to for the first time
Number threshold value；If so, executing step 608, step 602 is executed if not；
Step 608, record generating body are dynamic, variability index (can determine at this time be to tremble dynamic terminal) are reset, and repeat
Step 602 is executed to step 608.
When ortho, as shown in figure 9, being stacked between stable state, the stabilization shape after first time body is dynamic
State, the stable state before just the 2nd body moves, because shake state is only characterization body and moves number, i.e. calculating body moves to obtain mode
Are as follows: it is dynamic should just to calculate sleep body several times for several shake states.Therefore, in some embodiments, can be sentenced with some logics of economization
Disconnected step reduces operation consumption to simplify the process judged.Fig. 7 is a kind of sleep that another embodiment of the utility model provides
Body moves the flow diagram of monitoring method, to the explanation and illustration of each step in above method embodiment, in the present embodiment
It is equally applicable.As shown in fig. 7, this method comprises:
Step 701 acquires the barometric information to keep warm in space；Barometric information is arranged according to the sequence of acquisition time
Column form barometric information sequence；
Step 702 adds up the absolute value of the difference between adjacent two barometric information in each detection cycle
Obtain the amplitude of variation in each detection cycle；
Step 703 judges whether amplitude of variation is more than or equal to amplitude threshold, moves if so, determining and meeting default body
Rule of judgment executes step 704；If not, it is determined that be unsatisfactory for default body and move Rule of judgment, execute step 705；
Step 704 determines that generating body is dynamic；
Step 705 determines that non-generating body is dynamic.
The utility model embodiment is by judging whether the barometric information sequence in warming space meets stable state to trembling
Dynamically, then by trembling Dynamic- Recovery to stable state, to determine user, whether generating body is dynamic in sleep procedure.On the one hand air pressure is utilized
Sensor detects the body movement signal more much more complex than switching signal, realizes bigger application value.On the other hand, using sleeping
The variation of air pressure during sleeping in warming space is than using user's head movement in sleep procedure that the variation of acceleration is driven
It is more intuitive and conveniently to determine that the body of user moves.
It should be noted that giving the preferable implementation of the utility model in the specification and its attached drawing of the utility model
Mode, still, the utility model can be realized by many different forms, however it is not limited to which this specification is described to be implemented
Mode, these embodiments are not as the additional limitation to the content of the present invention, the purpose of providing these embodiments is that making
It is more thorough and comprehensive to the understanding of the disclosure of the utility model.Also, above-mentioned each technical characteristic continues to be combined with each other, and is formed
The various embodiments not being enumerated above are accordingly to be regarded as the range of the utility model specification record；Further, to this field
For those of ordinary skill, it can be modified or changed according to the above description, and all these modifications and variations all should belong to
The protection scope of the appended claims for the utility model.
