In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment one:
Referring to FIG. 1, Fig. 1 is a kind of flow chart of sleep monitor method in the embodiment of the present invention, this method includes following
Step:
S101, user's sleep signal is acquired using the piezoelectric transducer being located in mattress.
In embodiments of the present invention, can place on the bed for needing to carry out Sleep-Monitoring in advance has piezoelectric transducer
Mattress.Certainly, directly piezoelectric transducer can also be placed below mattress, allows piezoelectric transducer to the vibration on mattress
Or pressure change is converted to corresponding electric signal.Preferably, consider that piezoceramic transducer has contactless, high precision
Degree, low cost, high robust, it is easy to use the features such as, can be preferential to select piezoelectric ceramics sensing when selecting piezoelectric transducer
Device.Specifically, piezoceramic transducer can identify pressure change caused by small vibration, human heartbeat can be perceived and breathing causes
The variation of thoracic cavity jerk power, and it is converted into electric signal.Secondly cheap piezoelectric ceramic piece is conducive to equip on a large scale, and by
Can not have to directly contact human body in the pressure signal of detection can be collected, and the movements such as user's turn be allowed in use process, just
In use.User's sleep signal is acquired using piezoceramic transducer.
S102, it user's sleep signal is input in single-chip microcontroller carries out signal conversion processes, obtain target body life entity
Sign.
In embodiments of the present invention, the physics chain of the signal transmission between piezoelectric transducer and single-chip microcontroller can be built in advance
Road.Specifically, piezoelectric transducer can be connected by transmission circuit with single-chip microcontroller.Wherein, transmission circuit, which can be only, can be used for
Transmit the cable of user's sleep signal.Preferably, in order to ensure that signals transmission causes signal to lose because of reasons such as line losses
Very, user's sleep signal can successively be passed through to signal amplification, filtering and AD conversion processing.That is, can specifically be wrapped in transmission circuit
Include operation amplifier circuit and filter circuit and analog to digital conversion circuit.
In this way, by with operation amplifier circuit and filter circuit and analog to digital conversion circuit that user's sleep signal is defeated
Enter into single-chip microcontroller and carry out signal conversion processes, target body vital signs can be obtained.Wherein, target body vital signs has
Body includes heart rate and respiratory rate.
Wherein, signal conversion processes obtain the realization process of heart rate and respiratory rate, comprising:
Step 1: carrying out median filtering to user's dormant data, filtered signal statistics are exceeded with the mesh of respiration threshold
Number is marked, and records time interval；
Step 2: determining respiratory rate using targeted number and time interval；
Step 3: carrying out heart rate detection to user's dormant data, heart rate is obtained.
It is illustrated for ease of description, below combining above three step.
It is mingled with heart rate and other action signals, waveform in original signal by the collected respiratory movement of piezoelectric transducer
Without rule, need to be filtered signal and screen.In view of respiratory movement exhales the pressure meeting between a suction to mattress one
Difference, and then piezoelectric transducer user's sleep signal collected also will appear signal low ebb and signal peak, can be preset
Respiration threshold, the respiration threshold can be specially breathing upper threshold value and breathing lower threshold value.In this way, carrying out signal mistake by median filtering
Filter is denoted as respiration movement when signal is more than respiration upper threshold value and is lower than respiration lower threshold value, and records the time
Interval.For example, breathing upper threshold value can be 2500mv (millivolt), breathing lower threshold value can for 3000mv (2500mv here and
3000mv is amplified signal, and threshold value changes with amplification factor, and amplification factor is 10 times herein).Based on multiple time intervals and
Heart rate can be calculated in respiration rate.For example, being obtained when counting the respiration rate that time interval has reached one minute
It, can be directly using targeted number as respiratory rate to targeted number.
Correspondingly, the corresponding detection method for being used for respiratory rate can also be used to user's dormant data, heart rate is obtained, herein
No longer repeat one by one.
After seeing conversion to user's sleep signal using single-chip microcontroller, the available network mould specifically communicated to connect with single-chip microcontroller
Target body vital signs is transferred to server by block such as WIFI.
S103, target body vital sign is analyzed and processed using server, obtains sleep monitor result.
In view of human body is under different sleep states, the human life feature meeting different from presented, thus server
After receiving target body vital signs, it can be carried out at analysis based on sleep state of the target body vital signs to user
Reason, obtains sleep monitor result.
Specifically, respiratory rate and the corresponding sleep monitor result of heart rate can be determined according to sleep state decision rule；It sleeps
Dormancy monitoring result includes sleep duration, Depth of sleep, sleep initial time.
Based on how obtaining the concrete analysis of sleep duration, Depth of sleep and initial time of sleeping based on respiratory rate and heart rate
Treatment process can refer to the current common specific implementation being monitored based on heart rate and respiratory rate to the sleep state of user
Journey, this is no longer going to repeat them.
Preferably, it is contemplated that be based only upon heart rate and respiratory rate is handled and the sleep monitor result that obtains it is possible that
The problem of monitoring result inaccuracy.In order to solve this problem, the embodiment of the present invention proposes following two solution:
Scheme 1: carrying out median filtering to user's sleep signal, is more than the turn for turning over threshold value to filtered signal statistics
Number；Correspondingly, target body vital sign is analyzed and processed using server, obtains sleep monitor result, comprising: benefit
Sleep monitor result is modified with number is turned over.When there is turn movement in sleep procedure in user, piezoelectric transducer pair
The induction of turn movement becomes apparent from compared to the signal value variation of breathing and heartbeat etc., thus from user's sleep signal can
To detect to turn over number.Specifically section advanced in years carries out median filtering to user's sleep signal, then to median filtering is judged after
Signal is more than the turn number for turning over threshold value.It obtains after turning at number, the turn number directly can be sent to server.It is logical
In normal situation, turns over often, then illustrate that sleep quality is poorer；And turn is fewer, then illustrates that sleep quality is better.Thus, it can
Number is turned over by judgement to be compared with the sleep quality in sleep monitor result, determines whether turn over number and sleep quality
Matching is adjusted sleep quality based on number is turned over if mismatching.For example, if sleep quality is with 1 to 10 grade
Number, then can be turned over using n times reduces a grade is adjusted as standard, and wherein N can be the positive integer more than or equal to 1, such as
It is 3.
Scheme 2: there is into time point of the numerical value for a straight line as user from the bed time in user's sleep signal；User is slept
Dormancy signal returns the bed time as user from the time point that a straight line becomes non-rectilinear signal；Correspondingly, using server to target
Human body vital sign is analyzed and processed, and obtains sleep monitor result, comprising: when returning bed from bed time and user in conjunction with user
Between, sleep monitor result is modified.When in view of user in bed with user not in bed when, piezoelectric transducer is acquired
Signal be it is completely different.Specifically, when user in bed when, by the limb action of user, or as breathing and heartbeat life
Sign is influenced, the output signal of piezoelectric transducer can signal value can be fluctuation signal, and user not in bed when, without outer
In the case that boundary influences, straight line or the slight wave within the scope of certain signal value can be presented in the output signal of piezoelectric transducer
It is dynamic.Thus can the fluctuation situation to user's sleep signal be made whether monitoring in bed.Specifically, when user's sleep signal goes out
Existing numerical value is a straight line or when fluctuation range is less than preset threshold, can be considered that user leaves bed, when user's sleep signal is by always
When line becomes non-rectilinear or fluctuation range greater than preset threshold, it is considered as user and returns bed.It from the bed time and is returned the bed time based on user
Supplement confirmation can be carried out to user's sleeping time.Specifically, if user's sleep termination time after from bed, can be directly by user
The sleep termination time is redefined as from before the bed time, and correspondingly, if user sleeps, initial time can incite somebody to action before returning bed
User's sleep initial time was adjusted to time bed time.
In addition, user excessively also can determine that the sleep quality of user is bad from bed number in the period at night, that is, it is based on user
The sleep quality in sleep monitor result can also be adjusted from bed number.Specific adjustment realization process can be found in turn time
The adjustment of several pairs of sleep quality grades, this is no longer going to repeat them.
In practical applications, scheme 1 is not excluded for scheme 2, can association schemes 1 and scheme 2 to sleep monitor result into
Row amendment.
S104, sleep monitor result is shown in the user terminal.
After the sleep monitor result for obtaining user, sleep monitor result can be shown in user terminal.Specifically, working as quilt
The object of monitoring is school student, then can show the corresponding sleep quality monitoring result of each student in Dormitory management system
In, so that dormitory management personnel are checked in time and carry out corresponding management.
Sleep early warning can also be carried out by being preferably based on sleep quality monitoring.Sleep using sleep monitor result pre-
It is alert.Specifically, being more than preset from bed threshold value when there is monitored target from the bed time, it may be determined that monitored in the period at night
Object from bed time anomaly, can inform that related personnel be checked in time by early warning；Or, there is a large amount of be monitored in certain period
Object sleep quality is excessively poor or sleeping time is too short, also exportable warning information, so that related personnel is to influence monitored target
Factor checked, to ensure the sleep of monitored target.
