Monitor 20 is moved using above-mentioned sleep body to detect in user's sleep procedure, the specific detection method of the dynamic variation of body is such as Under:The body that will sleep moves in the application environment that monitor 20 is positioned over described in Fig. 1, and baroceptor 22 acquires in warming space 14 Air pressure, and by collected data transmission to processor 23, processor 23 obtains the barometric information, and is sentenced according to the barometric information Whether generating body is dynamic in disconnected user's sleep procedure.
Fig. 4 is provided by the embodiments of the present application, can be executed by above-mentioned processor, and the body for detecting user 11 moves number Sleep body move monitoring method.As shown in figure 4, this method includes:
Barometric information in step 41, the warming space of acquisition;Barometric information is arranged according to the sequencing of acquisition time, Form barometric information sequence.
The acquisition that baroceptor carries out air pressure may be used in the embodiment of the present application, air pressure sensing implement body can be to appoint What suitable sample frequency is acquired, for example, the gas in the form of a barometric information per second in the warming space of continuous acquisition Data, processor are pressed to obtain the barometric information and obtain barometric information sequence.
Barometric information sequence in this implementation is ranked up according to the sequencing of acquisition time, the barometric information sequence, It can react in special time period, the air pressure change situation in warming 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 extraneous air to enter in warming space, enables the air in warming space that heat exchange occurs with extraneous air, So that the variation of the air pressure Development pattern in warming space.
It therefore, can be by judging barometric information sequence whether comprising 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 actual conditions It determines.
Step 43 determines that generating body is dynamic in warming space.
Meet above-mentioned default body move condition when, it may be determined 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, it may be determined that the barometric information sequence do not include the regularity change Change, so that it is determined that user 11 is dynamic without generating body in warming space.
The embodiment of the present application moves condition by the way that whether the barometric information sequence judged in warming space meets default body, comes true Determining user, whether generating body is dynamic in sleep procedure.On the one hand it is detected using baroceptor more much more complex than switching signal Body movement signal realizes the application value of bigger.On the other hand, using the variation ratio of the air pressure in sleep procedure in warming space The variation of acceleration is driven using user's head movement in sleep procedure to determine that the body of user is dynamic more intuitively and conveniently.
As described above, when the action such as turning over occurs in warming space for user, gas that baroceptor detects Press the variation of data meeting Development pattern.For example, during user turns over, the hot-air in warming space is sent out with cool exterior air 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 Height changes repeatedly, in another example, after user completes turn action, air in warming 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., the 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, specifically determines method, 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 embodiment of the present application, the variation of atmospheric pressure state includes stable state and shake state.Stable state, which is air pressure, to be had slowly Downward trend state, shake state is that the state that changes repeatedly of height occurs for air pressure, corresponding with above-mentioned two situations respectively. In barometric information sequence, it is determined that above two state, you can determine the variation of atmospheric pressure state.It is marked in such as above-mentioned Fig. 8, Fig. 8 Occur a body it is dynamic when, the state of air pressure becomes dither state from stable state when restoring again to stable state, barometric information Variation tendency.
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 restoring to stable state, determine that generating body is dynamic in warming space.
Primary complete body defined in the present embodiment is dynamic, and barometric wave shape is as shown in figure 8, need by stable state, to shake state Restore again to stable state.This is because:If from the point of view of above-mentioned Fig. 8 is described as a longer period, Fig. 9 is can refer to, Fig. 9 is 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 It is front and back to have stable state, user can be excluded so just falls 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 by scene to facilitate.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 are 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 embodiment of the present application:Stable state and shake state, without to gas Pressure data are formed by waveform according to acquisition time and carry out detail analysis, only need to can be determined whether by the variation of atmospheric pressure state Generating body is dynamic.Further, stable state is restored to be defined as the primary of user to stable state again by the embodiment of the present application to shake state The adjustment for posture of sleeping, in the process, no matter user has turned body several times, and how many times have been moved in trick, are all only considered as primary sleep The adjustment of posture, and think that a body, which only has occurred, to be moved, the sleep of user can be acted and be simplified by this mode, make this skill Art scheme is simply preferably gone, 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 by stable state variation, then by trembling Dynamic- Recovery to the mode of stable state.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 Dynamic the undergone duration of secondary body.
Specifically, the logic step may include:
First, the amplitude of variation of barometric information in detection cycle is determined.
" barometric information in detection cycle " of the application meaning indicates several collected air pressure numbers in certain time period According to for example, when every five seconds for example is a detection cycle, " barometric information in detection cycle " then indicates several collected gas in 5 seconds Press data;I.e. " amplitude of variation for determining barometric information in detection cycle " indicates to determine the change of collected barometric information in 5 seconds Change amplitude.The absolute value of difference between adjacent two barometric information in each detection cycle is added up to obtain by the application Amplitude of variation in each detection cycle.
Here it is because the amplitude of variation of air pressure can more than or equal to amplitude threshold in detection cycle to draw amplitude of variation As the basis for estimation whether shaken in the current detection period, therefore, by current detection period definition in the present embodiment Judge the period to tremble dynamic origins.
Specifically, the amplitude of variation of air pressure can be by by the absolute value of the difference between adjacent two barometric information in detection cycle 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 with amplitude of variation come determine a certain period (i.e.:Tremble dynamic origins and judge the period) in the presence or absence of 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 by force Strong exchange, and air-flow itself will cause the variation of air pressure, so when body is dynamic, sensor can detect strong 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 embodiments of the present application is lower, the variation of air pressure The specific calculation of amplitude 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 judge the period Whether the variability index added is more than index threshold.Here it is because meeting accumulative variability index and being more than finger to draw variability index 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, is in this way:Standard atmospheric pressure is 1013hpa, and height above sea level is higher, and air pressure is lower, it is assumed that residing 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, the measurement of gained 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 more 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, i.e.,: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 variability index pause be 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 the resolution ratio of data that is measured due to baroceptor is 0.01hpa, in following table Data can be understood as the resolution ratio of 1.00pha if being only left 1hpa.In addition, in the present embodiment after adding up When variability index is 0, it is no longer kept to negative at this time, i.e., variability index declines air pressure more sensitive, based on the direction that increases.Tool Body please refers to table 2, and table 2 is that a kind of barometric information variation provided by the embodiments of the present application is lower, the specific calculating side of variability index Formula is illustrated:
Table 2
Difference between adjacent two barometric information being calculated by above-mentioned table 2 is:
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 it is 0 to keep variability index.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 to 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 if sensor is an exposure to outside bedding, lack the metastable environment in 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, i.e.,: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 in table 1, it sets the amplitude of variation of air pressure to 5hPa, index threshold is set as 100, i.e.,: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 more than index threshold 100, indicates shake state There is stable state before, the starting point that body moves the time has been recorded., i.e.,:This is trembled dynamic origins and judges the period to tremble dynamic origins, Atmospheric pressure state is become shaking state from stable state.
It can determine that trembling dynamic starting point determines by the amplitude of variation and accumulative variability index of air pressure:Atmospheric pressure state Become shaking state from stable state.
Finally, after determining and trembling dynamic origins, when trembling number that dynamic origins judge 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 be:When trembling dynamic starting point, air pressure in warming space by a rapid increase process, So that air pressure rises, change repeatedly in height trembling dynamic pilot process air pressure, 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 actual conditions.
Referring specifically to table 3 and table 4, table 3 and table 4 are a kind of first frequency threshold value provided by the embodiments of the present application when being 3, Also, the amplitude of variation that barometric information meets 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 application determines that gas strengthens the variation of state, and final basis using the amplitude of variation and variability index of barometric information 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 barometric information Absolute value, reduce influence of the environmental factor to measurement result, and the requirement to sensor accuracy.This judgment method, profit The body movement signal more much more complex than switching signal is detected with baroceptor, realizes the application value of bigger.
It should be noted 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, which meets, presets the dynamic condition of body, determines user Body of generation is dynamic, 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 warming space of form continuous acquisition in barometric information, processor obtains the barometric information and obtains barometric information sequence.

Step 604 judges whether variability index is more than index threshold, if executing step 605 (can determine to be to tremble at this time Dynamic starting point), if it is not, executing step 602;
Herein it should be explained that:Have the state of slow downward trend since stable state is air pressure, then stable state when Between in section, the difference between every two adjacent barometric information is that just, and in the period of stable state, variability index will increase.
In step 604, if variability index is more 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 more than amplitude threshold, and judges the starting point that step 603 is shake by accident.
The size of step 605, the amplitude of variation and preset amplitude threshold for comparing air pressure;
Step 606, the amplitude of variation for recording air pressure are less than the occurrence number 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, reset variability index (can determine to be to tremble dynamic terminal at this time), 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 calculate body and move to obtain mode because shake state is only characterization body and moves number For:It is dynamic should just to calculate sleep body several times for several shake states.Therefore, in some embodiments, some logics can be sentenced with economization Disconnected step reduces operation consumption to simplify the process judged.Fig. 7 is that a kind of sleep body that another embodiment of the application provides is dynamic The flow diagram of monitoring method, to the explanation and illustration of each step in above method embodiment, in the present embodiment equally It is applicable in.As shown in fig. 7, this method includes:
