Concrete: 3-axis acceleration sensor 131 data that mobile device receives calculate through four steps Go out respiratory frequency and alarm signal.First mobile device obtains wearable device 1 by BLE communications protocol On acceleration transducer data.Each data point has 3 data.The these three data first step is passed through Data calibration algorithm calibrated after data.The effect of calibration is the raw data of sensor to be changed Become the data required for later stage calculating, depending on its specific algorithm is according to the sensor used.After calibration Data can be submitted to band filter.Need exist for filtering out the data of direct current and high frequency, thus obtain Arrive and the corresponding data of breath rhythm.Typically the cut-off frequency of bandpass filtering can be arranged on (0.3HZ, 2HZ) interval.Band filter can use Bessel algorithm.Data after after filtering will be submitted to Fourier transform (FFT) link.Time-domain signal is changed into frequency-region signal by FFT, can effectively carry Take the frequency of breathing.After FFT system using extract maximum frequency domain range value respective frequencies as exhaling Inhale frequency.While calculating respiratory frequency, threshold value checks that all frequency domain digital absolute values are carried out by link Integration, the numerical value obtained and the threshold value pre-set compare.If less than threshold value, meaning that and not having Monitor enough respiratory movements, can report to the police.
A kind of detailed step that implement of modules is given below.
The every dimension of KXTJ9 acceleration transducer can be arranged to export 12 Bit data (XOUT, YOUT, ZOUT), represent the acceleration value of (-2G ,+2G).12 the most one-dimensional Bit datas by Two 8 bit register represent, are X respectivelyOUT_LAnd XOUT_H, YOUT_LAnd YOUT_H, ZOUT_L And ZOUT_H.Low register (XOUT_L) high 4 low 4 bit data representing 12 bits；High-order Depositor (XOUT_H) 8 most-significant byte data representing 12 bits.As shown in table 1: table 1 is The register architecture of KXTJ9 acceleration transducer.

The computing formula that the accekeration of every axle is concrete is as follows.
Xacc=(XOUT_H＜ ＜ 4+XOUT_L＞ ＞ 4)/4096*4G
Yacc=(YOUT_H＜ ＜ 4+YOUT_L＞ ＞ 4)/4096*4G
Zacc=(ZOUT_H＜ ＜ 4+ZOUT_L＞ ＞ 4)/4096*4G
Wherein, Xacc、Yacc、ZaccAccekeration for each axle；XOUT_LAnd XOUT_H、YOUT_L And YOUT_H、ZOUT_LAnd ZOUT_HRepresent represented by two 8 bit register the 12 of each axle respectively Bit data；G is terrestrial gravitation value.
As shown in Figure 8, for the frequency response of Bessel band filter.Bessel band filter is permissible Use following second order algorithm.
Y [n]=1/39.407 (x [n]-2x [n-2]+x [n-4])-0.605y [n-4]+2.677y [n-3]- 4.53y[n-2]+3.457y[n-1]
Data after digital filtering will submit to fast fourier transform (FFT) to calculate respiratory frequency. In order to appropriately assess respiratory frequency, it would be desirable to analyze the sampled data of about 20 seconds.If sampling Frequency is 10HZ, and for every one-dimensional data, we need to analyze 200 data points.In whole three number of axle evidences The frequency domain data that generates of FFT in, we find the frequency corresponding to absolute value of maximum to be exactly the frequency breathed Rate.
For example, Fig. 9 shows 200 initial datas of Z axis acceleration.Figure 10 show through Cross the Z axis acceleration information of bandpass filtering.Fig. 7 shows the Z axis frequency domain absolute value number after FFT According to.Wherein having reached maximum on the 8th frequency domain data point, corresponding respiratory frequency is (8/200) * sample frequency (10HZ)=0.4HZ, namely 24 beats/min.
Additionally, respiration information analyzes module 22 can also omit filtering link, in raw acceleration data On directly carry out FFT and calculate respiratory frequency and Threshold Alerts.Figure 11 shows on initial data direct The result of FFT.It can be seen that FFT frequency domain still reaches maximum in the 8th data point.So also may be used To detect respiratory frequency.Certainly after omission filtering link, the anti-interference of system is poor.
In order to monitor whether the situation of respiratory arrest, Threshold Alerts step has calculated three by all The absolute value accumulation of axle FFT frequency domain response is got up, if this total absolute value is less than previously given threshold Value, the situation turning out respiratory arrest occurs, and system will produce alarm signal.
Above FFT and Threshold Alerts calculate and can carry out once with every five seconds for example clock.This time interval is permissible Regulated according to the hardware computing capability of mobile device by system.Slip numeral Fourier can also be used to become Change the algorithm of (SDFT) to reduce the operation time of each FFT computing.
In addition to save the energy consumption of BLE communication, usual wearable device 1 accumulates multiple data point again Property be sent to data analysis system 2, data analysis system 2 must have corresponding buffering to receive these numbers According to.The most no longer describe in detail.
In addition to monitoring of respiration, system can also analyze wearer from the data of acceleration transducer and be No at sleep state, and the health of sleep towards, if baby is chronically at prostrate state, system can To report to the police.If wearer is tumbled, it is also possible to calculate from acceleration information.These calculate ratio Relatively simple direct, the most no longer describe in detail.
