Specific embodiment

Carry out the embodiment that the present invention will be described in detail below in conjunction with accompanying drawings and embodiments, thereby how the present invention is applied Technological means can fully understand and implement according to this to solve technical problem and reach the realization process of technical effect.

In order to obtain more user's physiological parameter by wearable device, preferably to determine the health status of user, Inventor is by a series of the study found that can be into one by the combination respiration parameter such as the heart rate of user, blood oxygen and kinematic parameter Step improves the accuracy judged user health situation.The present invention provides a kind of physio-parameter detection method, applied to being worn Positioned at the chest of user or the wearable device of abdomen when wearing, which includes being implanted with the fixation of strain effect material Band, the deformation sensory package with fixing band connection and the processor being connected with deformation sensory package.It is wearable that user wears this The expansion and contraction process of thoracic cavity or abdomen can draw the fixation band of the wearable device and deform upon when equipment breathes, deformation at this time Sensory package can detect fixed band since under tension deforms upon the deformation parameter of generation.And the deformation parameter be with The variation of the respiratory rate at family and it is changed, therefore based on deformation parameter changing rule can determine user breathing week Phase.By inquiring about correspondence of the different deformation parameter from different value of thrust, it may be determined that the pulling force pole in each respiratory cycle Big value and pulling force minimum, and based on the pulling force maximum and pulling force minimum in each respiratory cycle, calculate and obtain breathing ginseng Number, so as to improve the accuracy judged health state of user further combined with respiration parameter.

Technical solution of the present invention is described in detail below in conjunction with attached drawing.

Fig. 1 is a kind of structure diagram of one embodiment of wearable device of the embodiment of the present invention.This is wearable to set It is standby to include being implanted with the fixation band 101 of strain effect material, be connected deformation sensory package 102, Yi Jiyu with fixed band 101 The processor 103 that deformation sensory package 102 connects.

Fixed band 101 is used to the wearable device being fixed on the chest or abdomen of user.

In practical application, which can be the cortex band or other with elasticity for being implanted with strain effect material The fixation band of material.The fixation band 101 is passed through based on current new material technology in the fixed band manufacturing process of common material Nanometer technology adds in some strain effect materials for monitoring the use state of the fixation band, which can be carbon Nanotube either graphene material can realize the same function of similar sensor, with the deformation of the fixed band 101 of monitoring.

When deformation sensory package 102 is used to detect that fixed band 101 deforms upon, deformation parameter is generated.

When the fixation band 101 is fixed on the chest or abdomen of user, chest and abdomen can be caused when being breathed due to user Expansion and contraction movement certain pulling force is generated to fixed band 101, deformed upon so as to cause fixed band.Deformation sensory package 102 are connected with fixed band circuit for generating deformation parameter when detecting that fixed band 101 deforms upon, and send deformation ginseng It counts to processor 103.

Processor 103 is used to obtain the deformation ginseng generated when the fixed band 101 of the detection of deformation sensory package 102 deforms upon Number；Changing rule based on deformation parameter, determines the respiratory cycle；Different deformation parameter is inquired about to close from the corresponding of different value of thrust System, determines the pulling force maximum and pulling force minimum in each respiratory cycle；Based on the pulling force maximum in each respiratory cycle With pulling force minimum, calculate and obtain respiration parameter.

In practical application, the respiratory cycle of user can be determined based on the changing rule of deformation parameter, based on breathing week Phase can also directly calculate the respiration parameter for obtaining user.But due in actual use, due to electrostatic, magnetic field etc. it is extraneous because There is abnormal numerical value in the deformation parameter that element causes deformation sensory package 102 to generate, this results in detection acquisition respiration parameter and is not inconsistent Actual range is closed, it is abnormal detection occur.By taking respiration parameter is respiratory rate as an example, since static electricity on human body causes in wearable device Electric current changes, and it is 2000 times/S that detection is caused, which to obtain respiratory rate, this is clearly an abnormal data.Therefore, in order to avoid inspection The data exception for obtaining respiration parameter is surveyed, further determines that the pulling force in the respiratory cycle is very big on the basis of the respiratory cycle is determined Value and pulling force minimum.Pulling force maximum and pulling force minimum be after inquiring about the corresponding value of thrust of different deformation parameter, By carrying out data controls to each value of thrust in the respiratory cycle, screening and obtain after comparing.

Determining in the respiratory cycle after each corresponding value of thrust of deformation parameter, due to when user's air-breathing, thoracic cavity or Abdominal cavity is expanded, and air-breathing gradually increases value of thrust therewith, and thoracic cavity or abdominal cavity are shunk during expiration, and value of thrust is gradually reduced therewith.Therefore, The maximum of pulling force during value of thrust becomes larger in the respiratory cycle is determined as pulling force maximum, and determines that value of thrust gradually subtracts The minimum value of pulling force is pulling force minimum during small.Determining pulling force maximum and pulling force minimum in each respiratory cycle Data screening and comparison are carried out afterwards.

It whether within a preset range to first determine whether the pulling force maximum or pulling force minimum, recognizes if beyond preset range The fixed pulling force maximum or pulling force minimum are exceptional value, directly filter out the calculating for not participating in respiration parameter.For example, the pulling force pole Big value threshold value is 15N~8N, and the threshold value of pulling force minimum is 1N~3N；If think if the scope pulling force maximum or Pulling force minimum is exceptional value, is not included in the calculating process of respiration parameter.The pulling force maximum after exceptional value and drawing will be filtered out Power minimum is ranked up sequentially in time.

Then, judge to filter out whether the pulling force maximum after exceptional value or pulling force minimum are to change sequentially in time , for example, under normal circumstances, pulling force minimum is spaced appearance in chronological order with pulling force maximum, i.e., according to F_max1、F_min1、 F_max2、F_min2……；Either F_min1、F_max1、F_min2、F_max2... order be spaced appearance successively.Wherein, F_max1、F_max2It represents The pulling force maximum occurred successively in chronological order；F_min1、F_min2Represent the pulling force minimum occurred successively sequentially in time. If there is the pulling force maximum of at least two continuous adjacents or pulling force minimum, then illustrate the pulling force maximum after screening Or there are still exceptional values for pulling force minimum.For example, when there is abnormal shake, this shakes the maximum of corresponding waveform extremely And minimum, at least one numerical value is certainly existed not in pulling force threshold range, it is possible to which the situation of appearance is：1. the exception is trembled The maximum for moving corresponding waveform meets pulling force maximum threshold range, but this shakes the minimum certainty of corresponding waveform extremely It is unsatisfactory for pulling force minimum threshold range；Alternatively, 2. the minimum of the corresponding waveform of exception shake meets pulling force minimum threshold It is worth scope, but the maximum of the corresponding waveform of exception shake is necessarily unsatisfactory for pulling force maximum threshold range；It is alternatively, all discontented Sufficient pulling force maximum threshold range and pulling force minimum threshold range.Situation is 1. planted for the, is unsatisfactory for the corresponding abnormal of scope The minimum of the waveform of shake can be filtered out, then be just present with the situation of the pulling force maximum of two continuous adjacents, therefore can Judge that there are still exceptional values for the pulling force maximum after screening or pulling force minimum.If the drawing of at least two continuous adjacents Power maximum then only retains the maximum in the pulling force maximum of at least two continuous adjacents；If at least two continuous phases Adjacent pulling force minimum then only retains the minimum value at least two adjacent pulling force maximum.So as to by abnormal breathing Cycle filters out, and the respiration parameter obtained is calculated based on the pulling force maximum after data screening and comparison and pulling force minimum, Abnormal breathing parameter can be obtained to avoid detection, further improve the accuracy of detection of respiration parameter.

In the specific implementation, fixed band 101 is as the breathing of user is subject to different degrees of pulling force and generates different shapes Variable element, therefore the respiratory cycle of user can be determined by the changing rule of deformation parameter.When user's air-breathing due to chest Or abdominal expansion, the value of thrust that is subject in current breathing cycle of band 101 is fixed at this time gradually to be increased, the user when user exhales Chest or abdomen shrink, fix the value of thrust that is subject in current breathing cycle of band at this time and be gradually reduced, it is thus determined that breathing Pulling force maximum that band 101 is subject to and pulling force minimum are fixed in cycle can calculate the respiration parameter for obtaining user, the breathing Parameter can include respiratory rate, depth of respiration, breathing stability etc..

Actual detected in deformation sensory package 102 obtains the deformation parameter generated when fixed band 101 deforms upon and transmission To processor 103, due to being not easy to convert between deformation parameter and value of thrust, in practical applications can be right The fixation band 101 carries out calibration test in advance.It is previously obtained by calibration test between different value of thrust and different deformation parameter Correspondence and store into processor 103, processor 101 receiving deformation sensory package 102 transmission deformation parameter After can corresponding value of thrust directly be obtained according to correspondence matching.

Wherein, different deformation parameter can generate in the following way in advance from the correspondence of different value of thrust：

The stretching of 101 acceptance presupposition value of thrust of fixed band deforms upon, and records the deformation sensory package 102 successively and detect The deformation parameter of acquisition, then establishes default value of thrust and the correspondence of corresponding deformation parameter is stored into processor 103.

In the present embodiment, after the respiratory cycle is determined, closed by inquiring about different deformation parameter from the corresponding of different value of thrust System, it may be determined that pulling force maximum and pulling force minimum in each respiratory cycle can cause shape to avoid due to extraneous factor Variable element calculates and obtains abnormal breathing parameter extremely, further improves the accuracy of detection of respiration parameter, and then can be further Health state of user is judged based on respiration parameter.

In the embodiment of the present invention, strain effect material in fixed band 101 due to its special nature can be equivalent to it is variable Resistance so that the resistance value of fixed band 101 changes with the deformation of fixed band；Deformation sensory package 102 and fixed band Strain effect material connection in 101.

Strain effect material can include carbon nano-tube material or grapheme material, since it is with good mechanical property And electric conductivity can be implanted to by nanometer technology in fixed band 101, when fixed band 101 is deformed upon due to strain gauge material Also therewith deformation is generated its electric conductivity is caused to change, therefore the strain gauge material can be equivalent to variable resistor.For The stressing conditions of fixed band 101 can be preferably detected, three sections of implantations may be employed by three sections of the strain effect material point In the fixed band of implantation, it can divide three sections the strain effect material is implanted into fixation respectively generally according to the stressing conditions of the fixation band It is corresponded to 101 in position and the medianly zygomorphic position immediately ahead of user's abdomen or chest.

Divide three sections in fixed band 101 and implant strain effect material, the strain effect materials difference of point three sections of implantation is equivalent For the first variable resistor, the second adjustable resistance and the 3rd variable resistor.

Deformation sensory package 102 is connected respectively with the first variable resistor, the second adjustable resistance and the 3rd variable resistor, structure Written formula electric bridge oscillating circuit.

In the present embodiment, strain effect material is implanted by fixed band using three-stage implantation based on fixed band stressing conditions In, it can more accurately detect fixed band deformation caused by being breathed due to user and generate deformation parameter, ensure that deformation is joined Number breathes the correlation of rule with user, and acquisition respiration parameter is calculated so as to be based on deformation parameter.

In practical application, which respectively can with the first variable resistor, the second adjustable resistance and the 3rd Become resistance connection, form literary formula electric bridge oscillating circuit：

Wherein, deformation sensory package includes operational amplifier, the first capacitance, the second capacitance and the 4th resistance；

In order to preferably embody the connection relation of deformation sensory package 102 and variable resistor, literary formula is present embodiments provided Electric bridge oscillating circuit structure diagram.As shown in Fig. 2, operational amplifier uses dual power supply, the power supply of operational amplifier is just Pole connects the first power supply U_s1Anode, the power cathode connection second source U of operational amplifier_s2Cathode, the first power supply U_s1's Cathode and second source U_s2Anode connection after be grounded.3rd variable resistor R3 one end and the inverting input of the operational amplifier Connection, other end ground connection.Output with the operational amplifier after one end of 3rd variable resistor R3 is connected with outer connecting resistance Rf End connection, wherein, the 3rd variable resistor R3 determines the amplitude of circuit output signal and whether there is.Specifically, the 3rd variable resistor R3 connects to form a negative-feedback circuit of operational amplifier with resistance Rf, and when deformation is not present in the fixation band 101, the 3rd can Become resistance R3=0 Ω, at this time the reverse inter-input-ing ending grounding of the operational amplifier, negative-feedback 0, therefore the letter of the operational amplifier Number output is for 0 (i.e. no signal output).When the fixation band 101 is there are during deformation, the 3rd variable resistor R3 is generated because of stress Resistance value, as fixed 101 stress of band is of different sizes, also the moment changes the resistance value of the 3rd variable resistor R3, exports signal at this time It is outwards exported by output terminal by the operational amplifier, the resistance value phase of the range value of the output signal and the 3rd variable resistor R3 It closes.

In addition, the first capacitance C1 and the first variable resistor R1 series networks in series, one end of the series network and fortune The in-phase input end connection of amplifier is calculated, the other end of series network is connected with the output terminal of the operational amplifier.Second capacitance C2 and the second adjustable resistance R2 is in parallel to form parallel network, and one end of parallel network and the in-phase input end of operational amplifier connect It connects, the other end ground connection of parallel network.Wherein, the first capacitance C1 is equal with the second capacitance C2 capacitances, the first variable resistor R1 With the second adjustable resistance R2 due to symmetrical stress, change in resistance is identical, at this time the first capacitance C1, the second capacitance C2, The RC connection in series-parallel frequency-selective network that one variable resistor R1 and the second adjustable resistance R2 is formed forms self-excitation frequency selection circuit, exports signal Frequency size is determined by R1 and R2 resistance values.

Output terminal of the output terminal of the operational amplifier as this article formula electric bridge oscillating circuit, the fixed band 101 of output detection Deformation and generate output signal i.e. deformation parameter, it can thus be appreciated that the frequency and amplitude of deformation parameter can with fixed band 101 by Power and deformation size and change.But since the first variable resistor R1, the second adjustable resistance R2 and the 3rd variable resistor R3 are Real-time change and be not easy to measure and calculate, therefore can by detect this article formula electric bridge oscillating circuit export signal know The value of thrust at corresponding moment.

In the present embodiment, the fixed band deformation of deformation sensory package detection is further illustrated by literary formula electric bridge oscillating circuit The concrete principle of Shi Shengcheng deformation parameters can further appreciate that the strain effect material in the fixed band of implantation through the above Electric conductivity it is related to the stress of fixed band, the resistance value with the variation strain effect material of stress also changes direct shadow therewith The variation of deformation sensory package generation deformation parameter is rung, and its changing rule is consistent with the respiratory rate of user.

Fig. 3 is a kind of structure diagram of another embodiment of wearable device of the embodiment of the present invention.This is wearable Equipment removes the fixation band 101 for being implanted with strain effect material included in Fig. 1 embodiments, the deformation being connected with fixed band 101 passes Outside sense component 102 and the processor 103 being connected with deformation sensory package 102, envelope detector 104 and mirror can also be included Frequency device 105.

Compared with traditional direct-current bridge (for example, double bridge or wheatstone bridge) circuit, literary formula electric bridge oscillating circuit is defeated What is gone out is AC signal, therefore fixed band can be judged in terms of the amplitude of AC signal, that is, deformation parameter and frequency two The size of value of thrust suffered by 101.Respiratory rate in view of people is 20 times per minute or so, therefore sets envelope detector 104 And the sample frequency of frequency discriminator 105 is 50Hz.

Deformation sensory package 102 connects envelope detector 104 and frequency discriminator 105 respectively, by envelope detector 104 with And frequency discriminator 105 is connected respectively with processor 103.

Envelope detector 104 is used to detect the range value of deformation parameter, and sends range value to processor 103；

Frequency discriminator 105 is used to detect the frequency values of deformation parameter, and sends frequency values to processor 103.

Processor 103 obtain deformation sensory package 102 detect the deformation parameter that is generated when fixed band 101 deforms upon can be with Including：Receive the frequency values that the range value of the transmission of envelope detector 104 and frequency discriminator 105 are sent.

The deformation sensory package 102 is detected when fixed band 101 deforms upon after generation deformation parameter, by the deformation of generation Parameter divides two-way to transmit.Envelope detector 104 is transmitted to all the way, and detection acquisition is carried out to the deformation parameter by envelope detector Its range value is simultaneously sent to processor 103；Another way be transmitted to frequency discriminator detection obtain its frequency values be sent to processor 103. Processor 103 determines that the respiratory cycle can include：Changing rule based on the range value that envelope detector 104 is sent, determines to exhale Inhale the cycle.

Wherein, the range value of deformation parameter be as the fixed size under tension value is changed, fixed band by Gradually increase to value of thrust, range value is a gradual increased process；The value of thrust that fixed band is subject to is gradually reduced, range value It is a process being gradually reduced.Therefore the respiratory cycle of user can be determined according to the variation of range value, can usually be determined One of range value variation rises and falls the cycle as a respiratory cycle.The frequency values of the deformation parameter can represent width in the unit interval The number of angle value fluctuations namely the respiratory rate of user, the respiratory rate are corresponding with the respiratory cycle.But by it is above-mentioned can Know, since abnormal shake occurs in the range value that the extraneous factors such as electrostatic, magnetic field can cause detection to obtain so that an actual breathing Multiple wave crests or two troughs are likely to occur in cycle, therefore determine that the respiratory cycle will calculate based on the fluctuations of range value Obtain abnormal respiratory rate.

It is illustrated in figure 4 the deformation parameter oscillogram of the deformation sensory package 102 output.Due to the range value of deformation parameter It is related with the pulling force size that fixed band 101 is subject to, it is known that its amplitude period of change is identical with the respiratory cycle of user, therefore handles The changing rule for the range value that device 103 is sent according to envelope detector 104, it may be determined that the cycle that rises and falls corresponds to the one of user A respiratory cycle.

Further, in order to avoid being the respiratory cycle since extraneous factor causes range value abnormal Jitter Calculation occur.It can Selection of land, processor 101 inquire about different deformation parameter and the correspondence of different value of thrust, determine the pulling force in each respiratory cycle Maximum and pulling force minimum can include：Inquire about different deformation parameter in range value and the corresponding value of thrust of frequency values； Determine the pulling force maximum and pulling force minimum in each respiratory cycle.

It can be seen from the above, in practical application calibration test can be carried out to the fixation band 101 to this in advance, default pulling force is established The correspondence of value and corresponding deformation parameter is simultaneously stored into processor 103.The default value of thrust pass corresponding with deformation parameter System is default value of thrust and the range value and the correspondence of frequency values in deformation parameter, is that part is pre- in as shown in table 1 below If the correspondence of value of thrust and deformation parameter.

Table 1 presets the correspondence of pull-up values and deformation parameter

Processor 103 determines the range value of different deformation parameter in each respiratory cycle and the corresponding drawing of frequency values first The value of thrust for inquiring about acquisition is ranked up by force value by size, and then determines the pulling force maximum in each respiratory cycle and drawing Power minimum.

On the basis of exceptional value is filtered out, based on the pulling force maximum and pulling force minimum in each respiratory cycle, calculate Obtaining respiration parameter can include：

The pulling force minimum calculated in each respiratory cycle is corresponding with the pulling force maximum in the adjacent latter respiratory cycle Detection time it is poor, obtain the inspiratory duration in each respiratory cycle.

Calculate the pulling force maximum detection corresponding with the pulling force minimum in the same respiratory cycle in each respiratory cycle Time difference obtains the expiratory duration in each respiratory cycle.

It is, of course, also possible to further determine the amplitude of variation of the range value in each respiratory cycle between adjacent deformation parameter Size, illustrate if amplitude of variation is larger breathing it is not steady enough, show if amplitude of variation is smaller breathing it is more steady.Also The depth of respiration in the respiratory cycle can be determined by judging the size of the pulling force maximum in each respiratory cycle, if Pulling force maximum is more than average tension maximum in the respiratory cycle, then depth of respiration is shown to be, if less than average tension pole Big value is then shown to be shallow breathing.

In the present embodiment, the range value and frequency for obtaining deformation parameter are detected respectively by envelope detector and frequency discriminator Value obtains corresponding value of thrust in the respiratory cycle so as to which range value and frequency values of the processor based on deformation parameter can be inquired about, Processor is only by comparing the pulling force maximum and pulling force minimum obtained in the respiratory cycle, you can based on pulling force maximum and drawing Power minimum, which calculates, obtains respiration parameter, can greatly improve the treatment effeciency of processor, can obtain in real time respiration parameter with Judge the health status of user.
