Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
This method embodiment is mainly used in nose pressure detector, and nose pressure detector can acquire use by pressure sensor
The nose at family presses data, and whether analyze collected nose pressure data normal come the nose pressure for judging user.
Referring to Fig. 1, Fig. 1 is the flow chart of nose pressure detection method embodiment of the present invention.Method includes the following steps:
Step S101: the nose obtained in nose pressure detection sliding window presses data.
Nose pressure detection sliding window refers to detection cycle.And the nose pressure data in nose pressure detection sliding window can be understood as
In detection cycle, this collected nose of duration pressure sensor institute presses data.The specific duration of detection cycle is not limited
It is fixed, different value can be set according to all ages and classes, be traditionally arranged to be the respiratory cycle of normal person.Such as: normal adults are quiet
When per minute about breathe 16 to 18 times, i.e., detection cycle can be 3.5 seconds.It should be understood that the specific implementation of step S101
Mode can have following two.
(1) it is pressed in detection sliding window in the nose, sampling nose is obtained according to preset sampling step length and presses data, the nose
Pressure detection sliding window is slided backward by sampling step length.
Wherein, sampling step length is the sampling period that data are pressed according to nose, such as: if the sample frequency of nose pressure data is
25Hz, it is 0.04 second that nose, which presses the sampling period of data, and when detection cycle is 3.5 seconds, then the nose of a detection cycle presses data
It is 3.5*25, is 88.When nose presses detection sliding window to slide backward, then nose earliest in nose pressure detection sliding window presses number
According to the nose pressure data replacement newly entered.Pressing detection sliding window due to nose is slided by sampling step length, then nose pressure detection sliding
Window is every to be slided, and 1 data can be slided backward.As shown in Fig. 2, 1. nose pressure detection sliding window includes the number of a1 to a88
According to, after sliding backward a sampling step length, become nose pressure detection sliding window 2. comprising the data of a2 to a89.
(2) it is pressed in detection sliding window in the nose, sampling nose is obtained according to preset sampling step length and presses data, nose pressure inspection
It surveys sliding window and presses detection sliding window length to slide backward by nose.
The sliding type for pressing detection sliding window length to slide backward by nose is compared to the cunning slided backward by sampling step length
Flowing mode, nose pressure data update more, such as: when sample frequency is 25Hz, nose pressure detection sliding window is 3.5 seconds, nose
The every sliding of pressure detection sliding window is primary, then can be backward by 88 data of sliding, so that the nose pressure in nose pressure detection sliding window
Data become next 88 data.As shown in figure 3,3. nose pressure detection sliding window includes this 88 data of a1 to a88, slide backward
Dynamic primary, then 4. nose pressure detects sliding window comprising this 88 data of a89 to a176.
It is to be understood that the sliding step of nose pressure detection sliding window is not limited to foregoing description step-length, or its
Its step-length, no longer limits herein.
Step S102: judge the nose pressure data discrete degree reflected in nose pressure detection sliding window characteristic value whether
Less than preset first threshold value.If so, thening follow the steps S103a.If it is not, thening follow the steps S103b.
And the specific value of preset first threshold value is not construed as limiting, and can be determined by experiment.
Step S103a: determine that there are noses to press deletion events.
Nose pressure deletion events refer to that user's breathing is exceptionally weak, alternatively, breathing no more.Since human body is in eupnea,
It exhales and the air pressure of air-breathing generation differs greatly, on the contrary, if nose pressure detects the discrete journey of nose pressure data in sliding window
Very little is spent, that is, exhales and the nose of air-breathing pressure data differs very little, it can be said that the shallow breathing of bright user, so as to think to use
Family occurs nose and presses deletion events.In brief, the characteristic value of the nose pressure data discrete degree in reflection nose pressure detection sliding window
Are as follows: it is pressed in detection sliding window in the nose, the difference of the maximum nose pressure data sampled and the minimum nose pressure data sampled
Absolute value.In some embodiments, which can be understood as very poor, the pole of nose pressure data in nose pressure detection sliding window
Difference is the characteristic value of the relatively common dispersion for evaluating one group of data, can effectively reflect the fluctuation of one group of data
Range.Certainly, in nose pressure detection sliding window the characteristic value of reflection nose pressure data discrete degree be also not limited to it is very poor, can also be with
It is the characteristic value of other reflection dispersion degrees, such as: such as variance and standard deviation.
Step S103b: determine that there is no noses to press deletion events.
Referring to Fig. 4, Fig. 4 is a kind of flow chart of nose pressure detection method of another embodiment of the present invention, the present embodiment with
Above-described embodiment the difference is that, after step S103a, method further include:
Step S104: deletion events are pressed to determine that nose presses missing times according to the nose.
Specifically, it is primary to be then denoted as nose pressure missing when nose pressure deletion events are that individually occur.
When nose pressure deletion events continuously occur, by the number for nose pressure deletion events continuously occur divided by default second
It rounds up after threshold value, the value after rounding is determined as nose pressure missing times.
And continuously occur nose pressure deletion events be primarily due to user continuously breathe for a period of time it is all fainter, such as:
User's shallow breathing for 5 seconds.If user continues the overlong time of shallow breathing, but still it is considered merely as a nose pressure missing
Less rationally, so the default second threshold in this step is the maximum time in order to limit a nose pressure missing, to avoid this
Kind irrationality.In order to make it easy to understand, when determine press deletion events there are nose when, can be considered nose pressure detector output 1, when not depositing
When nose presses deletion events, nose pressure detector output 0 can be considered, so, when each nose pressure detection sliding window slides backward, nose
Pressure detector can all export 1 or 0.As shown in figure 5, continuously occur 1 has 17 times, i.e., continuously there is the number of nose pressure deletion events
Be 17, if it divided by the result that rounds up after 5 be 4 that default second threshold, which be 5,17, so 17 noses continuously occurred press it is scarce
Accident part can be considered as 4 nose pressure missings.
Specific value for presetting second threshold is not construed as limiting, and can be determined according to experiment.Referring to Fig. 6, Fig. 6 is
A kind of flow chart of nose pressure detection method of third embodiment of the invention, the present embodiment and above-described embodiment the difference is that,
After step s 104, method further include:
Step S105: missing times are pressed to determine whether there is apnea according to the nose.
If user, there are apnea, the oxygen that user's inspiration is gone comes few than normal person, thus influence its health and
Memory.And nose pressure missing times can reflect the nasal airflow amount and user's adnormal respiration duration of user, so as to
Using as judge user whether there is apnea foundation.
Specifically, pressing missing times to determine whether there is apnea according to the nose includes following two mode.
(1) by all noses occurred in sleep cycle pressure missing times summation, the nose pressure missing times after judging summation are
It is no to be greater than default third threshold value, if it is, determining that there are apneas.
Sleep cycle refers to the duration of user's sleep, such as: the time of sleep at night.User can open nose pressure before sleeping
Detector closes nose after waking up and presses detector, takes the nose during sleep to press deletion condition so as to obtain it.If user's sleep period
Between only 1 time or twice nose pressure missing, this may be incident, and being not enough to think user, there are apneas.On the contrary, such as
There are many nose pressure missing times of the fruit user during sleep, it may be considered that there are apneas by user.And default third threshold value
It can also be determined by experiment.
(2) whether the maximum value in all noses pressure missing times occurred in statistics sleep cycle, judge the maximum value
Greater than default 4th threshold value, if it is greater, then determining that there are apneas.
Since one of the symptom of apnea syndrome is that occur respiratory air flow during patient sleeps faint, and continues
Time is more than 10 seconds, and the maximum duration of the continuous nose pressure missing during can reflecting user's sleep of the maximum value in this step, instead
For it, it is possible to by maximum value and default 4th threshold value comparison, to judge user with the presence or absence of apnea.
Specific value for presetting the 4th threshold value is not construed as limiting, and can be determined according to experiment.
The embodiment of the present invention presses the nose in detection sliding window that data discrete degree is pressed to judge user's nose pressure by a nose
The case where missing, to judge that user provides foundation with the presence or absence of apnea, to make user when itself breathing appearance exception
It can find in time.
