Element determines.For example, when the number of the sensor generally touched is 4, then can be by m value when human normal is fallen asleep
4。
Due to corresponding with a micro-tremor signal sensor per physiological signal all the way.Therefore, it is equivalent to and senses this p
Any adjacent collected physiological signal of m sensor in device carries out detection and gets breath signal, exhales when adjacent m
When suction signal meets preset Rule of judgment, it is believed that the road the m physiological signal is corresponding with one human body (i.e. monitoring object), into one
Step ground, after determining that the adjacent physiological signal in the road m is corresponding with a monitoring object, processor 130 can count physiologic information prison
Survey the quantity of monitoring object on pad 100.
Default Rule of judgment herein refers to the Rule of judgment for judging to whether there is marked difference between different physiological signals.
It can determine between the different physiological signal of multichannel whether there is marked difference by the preset Rule of judgment, if multichannel is different
Physiological signal have significant difference, then it is assumed that be not belonging to the same monitoring object, then terminate to judge；If the different life of multichannel
It manages signal and does not have significant difference, it is determined that the human body of adjacent micro-tremor signal sensor contacts belongs to the same monitoring pair
As.The preset condition specifically can according to the actual situation or the needs of detection accuracy are determined.In some embodiments, this is pre-
If Rule of judgment may include following two:
1, there is respiratory waveform in the physiological signal of the road m, and at least there is physiological signal all the way in the physiological signal of the road m
Wave-shape amplitude be greater than preset first amplitude threshold.
2, in the physiological signal of the road m, per the waveform frequency of physiological signal all the way in preset frequency range, and waveform
Frequency Accumulated deviation value is in preset deviation range.
" the first amplitude threshold " in condition 1 is a preset numerical value, as judging whether waveform signal belongs to normally
Human body respiration movement standard, first amplitude threshold can by count normal person the corresponding respiratory waveform of respiratory movement after
It obtains.
The Accumulated deviation value of waveform frequency in condition 2 is the fluctuating range of waveform frequency, in the present embodiment, can be with
It is used to indicate that the statistic of the amplitude of variation size of waveform frequency is measured using variance or standard deviation etc..For example, can be with
By test of many times or big data analysis, the threshold value of the standard deviation of waveform frequency is determined.Then phase is judged by the threshold value
Whether the adjacent road m physiological signal meets Rule of judgment 2.
In the present embodiment, Rule of judgment 1 is to be implicitly present in for clear in this m micro-tremor signal sensor
The human body (i.e. monitoring object) of breathing；Rule of judgment 2 is for clear in this m micro-tremor signal sensor, is identical people
In breathing (i.e. same monitoring object).As a result, by above-mentioned two Rule of judgment, that is, it can determine whether certain road m physiological signal is deposited
In corresponding monitoring object.After successively carrying out detection judgement to the whole road p physiological signals, it can calculate corresponding
The quantity of monitoring object.
Step 35 passes through preset signal processing algorithm, extracts from the physiological signal of the adjacent road m corresponding with monitoring object
Physiologic information.
Determine the adjacent physiological signal in the road m and a monitoring object to it is corresponding when can according to the adjacent road the m physiological signal,
By the integration of signal and processing operation etc., determine that heart rate, respiratory rate and the body of corresponding monitoring object move the physiology such as number
Information.In practical calculating process, the adjacent road m physiological signal can be handled by preset signal processing algorithm, with
Obtain different physiologic informations.
The signal processing algorithm specifically can be any suitable, can isolate the algorithm of different physiologic informations.For example,
It can be and the adjacent road m physiological signal is directly filtered, separate signal aroused in interest, breath signal and the body movement signal obtained, or
Person is using Signal separators sides such as blind source separating, independent component analysis (independent component analysis, ICA)
Method isolates corresponding breathing, aroused in interest, body movement signal from the signal of the road m.
In further embodiments, small wavelength-division can also be used per physiological signal all the way in the physiological signal of the road m first
Solution method isolates aroused in interest, breathing and body movement signal from each road signal.It then, then will be from the letter aroused in interest of the road m Signal separator out
Number, breath signal and body movement signal be overlapped to obtain the final signal aroused in interest of monitoring object, breath signal and body movement signal.
Step 36, the quantity and the corresponding physiologic information of each monitoring object for recording monitoring object.
After the quantity of 130 statistical monitoring object of processor and the physiologic information of each monitoring object, processor 130
It can be recorded in specific memory, corresponding terminal can also be output to by above-mentioned wireless communication module 170
In equipment, as basic data, it is supplied to subsequent applications.
It should be noted that the record is only intended to indicate that processor 130 obtains the behavior of these data, not at restriction
Reason device 130 needs to be implemented corresponding record operation.Processor 130 can also lead to after calculating the corresponding physiological data of acquisition
It crosses wireless communication module to be real-time transmitted in other equipment, realizes the detection function for monitoring object.
Below in conjunction with specific example, detailed description calculated the separation of signal aroused in interest, breath signal and body movement signal
Journey.
Embodiment 1: isolating breath signal from physiological signal, and the breathing frequency of monitoring object is calculated according to breath signal
Rate.
Firstly, the target breath signal to the collected voltage waveform of micro-tremor signal sensor carries out Fourier transformation.So
Afterwards, it is more than the spectral peak of preset energy threshold in the target breath signal after determining Fourier transformation, that is, it is maximum finds energy
Preceding several spectral peaks.
After finding after the biggish spectral peak of these energy, the corresponding respiratory rate of the spectral peak is calculated, as candidate
Respiratory rate.Finally, selecting most reasonable respiratory rate from the candidate respiratory rate in conjunction with the historical data of monitoring object
Respiratory rate as monitoring object exports.
In the present embodiment, which refers to the case where respiratory rate before monitoring object.It can pass through phase
Represented by the statistics project answered, such as can be represented by the median by history respiratory rate.The most reasonable breathing frequency
Rate refers to candidate respiratory rate closest with historical data, or meeting historical data situation of change the most.
Since human body respiration is along with the fluctuating of thorax, the fluctuating is more obvious, the breathing of micro-tremor signal sensor acquisition
Signal is stronger.In view of the breath signal period is long, the probability for occurring multiple peak valleys in monocycle respiratory waveform is higher.Therefore, it adopts
It is easy erroneous detection peak valley when in fashion described above can be very good that Waveform Method is avoided to detect, respiratory rate is caused to calculate the problem of inaccuracy.
Embodiment 2: isolating signal aroused in interest from physiological signal, and determines therefrom that monitoring object heart rate:
Firstly, the baseline drift of removal target signal aroused in interest, obtains standard signal aroused in interest.Time domain removal specifically can be used
Baseline drift method realizes the filtering for low frequency signal.It is of course also possible to realize that filtering is aroused in interest using other suitable algorithms
The effect of low frequency signal in signal, such as wavelet decomposition method, Empirical mode decomposition (EMD) etc..
It is then detected that the wave crest point and trough point of standard signal aroused in interest.Wave crest point and trough point are screened according to dynamic threshold,
Obtain target wave crest point and target trough point.Finally, the spacing for determining target wave crest point and target trough point is monitoring object
Heart rate.
It since the human body signal aroused in interest of micro-tremor signal sensor acquisition is weaker, and is easy to be interfered by breath signal, extract
It is more difficult out.Wherein, the low frequency signal in voltage waveform signal is more significant for effect of signals aroused in interest.Therefore, this reality
It applies in example, can be good at improving the quality of signal aroused in interest to the operation that filters out of low frequency signal first, it is ensured that the standard of rate calculation
True property.
Embodiment 3: isolating body movement signal from physiological signal and calculates body moves number.
Since micro-tremor signal sensor is very sensitive with vibration signal to pressure, when body is dynamic to be occurred, micro-tremor signal sensing
The voltage waveform of device output can mutate and even be saturated.Therefore, in the present embodiment, according to the mutation of voltage waveform and saturation
As body movement signal.
The dynamic statistical for whether occurring to move number with body of body is specific as follows:
Firstly, can determine that a body motion occurs when the wave-shape amplitude of voltage waveform is repeated several times more than threshold value.The threshold value
The number for being more than repeatedly can be arranged according to the actual situation, such as can be set to when wave-shape amplitude is repeatedly more than 3 subthresholds
When, determine that generating body is dynamic.Secondly, being in saturation (being continuously maintained in a high position) in voltage waveform, and continue in a period of time
It is interior, it can also determine that generating body is dynamic.
In the present embodiment, the dynamic condition counted of a body is carried out are as follows: voltage waveform is in a saturated state at least to continue 3s,
And generating body dynamic interval time is at least 20s.As a result, by being continued to monitor to body movement signal, that is, can determine at one section
In time, the dynamic frequency of the number and body that monitoring object generating body is moved.
In some implementations, heart rate, respiratory rate and body dynamic time for the monitoring object obtained being calculated based on processor 130
These physiologic informations of number can also further determine the sleep state of monitoring object after corresponding logical operation.Tool
Body is referring to Fig. 4, Fig. 4 is a kind of physiologic information monitoring method 400 that another embodiment of the utility model provides, above-described embodiment
In it is equally applicable in the present embodiment to the explanation of each step, this method comprises:
Step 41 receives the 1st road to pth road physiological signal, and detection is per the breath signal in physiological signal all the way.
Step 42 judges in the physiological signal of the 1st road to pth road it is pre- whether the breath signal of the adjacent road m physiological signal meets
If Rule of judgment, if it is not, execute step 33, if so, execute step 34.
Step 43 terminates.
Step 44 determines that the adjacent physiological signal in the road m is corresponding with a monitoring object, and the quantity of statistical monitoring object.
Step 45 passes through preset signal processing algorithm, extracts from the physiological signal of the adjacent road m corresponding with monitoring object
Physiologic information.
Step 46, the quantity and the corresponding physiologic information of each monitoring object for recording monitoring object.
Step 47 moves number according to the heart rate of monitoring object, respiratory rate and body, determines the sleep shape of monitoring object
State.
In general, can exist when human body lies down on mattress from regaining consciousness to falling asleep and from falling asleep awake state
Variation, the sleep state specifically refer to different conditions of the human body (i.e. monitoring object) on mattress.It changes in sleep state
When, the corresponding heart rate of monitoring object, respiratory rate and body move number and occur to change accordingly.For example, human body awakening when,
It can turn over, the movement such as wave, then the heart rate of human body and respiratory rate increase accordingly, and the body of human body moves number and also accordingly increases
Add.Therefore, the sleep state of human body can be determined by moving number according to the heart rate of the human body monitored, respiratory rate and body.Tool
Body, can by judging monitoring object, whether generating body is dynamic in the given time, and the variation width of heart rate and respiratory rate
Whether degree exceeds preset second amplitude threshold to determine sleep state locating for monitoring object.
" predetermined time " herein refers to time, such as 1min or 10min of specific length etc..Normal human is sleeping
When state, motion frequency is lower, usually will not frequently act.Therefore, through statistics normal human when falling asleep, between body is dynamic
Interval time rule, can determine the predetermined time." the second amplitude threshold " herein is for measuring heart rate and breathing letter
The judgment criteria of number amplitude of variation, the second amplitude threshold can sleep by counting common people when heart rate and breath signal become
The range of change amplitude obtains, personalized adjustment can also be carried out according to the actual conditions of user.
On the one hand, if non-generating body is dynamic in the given time for monitoring object, and the amplitude of variation of heart rate and respiratory rate does not have
When having beyond the second amplitude threshold, then show that the activity of monitoring object at this time is inactive, physiologic information is in very stable shape
State, it is believed that monitoring object has been in hypnagogic state.
On the other hand, if generating body is dynamic in the given time for monitoring object, judge that monitoring object is sent out in the given time
Raw body moves number and whether exceeds whether the time that preset frequency threshold value or generating body are moved exceeds the preset duration.It should
Preset frequency threshold value and preset duration can be obtained with test of many times or big data analysis.If monitoring object is predetermined
The dynamic number of the body occurred in time the time dynamic more than frequency threshold value or generating body exceeds the preset duration, then can recognize
Waking state is in for monitoring object.When generating body is dynamic in the given time for monitoring object, further judge that body moves number,
Monitoring object can be excluded in sleep it is possible that the dynamic interference of body once in a while.Meet the dynamic judgement of above-mentioned body twice simultaneously, i.e.,
Show that monitoring object is in a more active state at this time, it is believed that the sleep state of monitoring object is awake.
In some embodiments, in order to extend the function that physiologic information monitoring is padded, its intelligence degree is improved.Such as Fig. 4 institute
