The invention sets the U-shaped pillow, the information acquisition device is arranged on the U-shaped pillow, and the U-shaped pillow is as close to a user as possible under the non-contact condition, so that the U-shaped pillow can ensure that the information acquisition device moves along with the user and does not cause discomfort to the user; and meanwhile, the respiration detection device is integrated on the U-shaped pillow, so that the pillow is convenient for a user to carry, can be used under other outdoor conditions such as a journey, an office and the like, and can be used for detecting the sleeping state of the user in a full time, and meanwhile, the U-shaped pillow can be used for effectively protecting the cervical vertebra.
Specifically, the information acquisition device of the present invention includes: the snore collecting device 201 and the expiration pressure sensing device 202 are arranged outside the fabric outer sleeve 104, the expiration pressure sensing device 202 is specifically a pressure sensing curved surface arranged outside the fabric outer sleeve 104, the snore collecting device 201 and the expiration pressure sensing device 202 are connected with two ends of the memory metal support 101 through the gooseneck 203, the gooseneck 203 penetrates through the fabric outer sleeve 104, the snore collecting device 201 and the expiration pressure sensing device 202 respectively adopt independent signal processing modules to perform signal processing, the two groups of digital-to-analog conversion modules perform digital-to-analog conversion on the two groups of waveform data and then transmit the two groups of waveform data to the central processing unit, the beam forming technology is adopted to obtain the two groups of waveform data, the central processing unit performs superposition amplification processing on the two groups of waveform data to obtain a breathing waveform diagram, and the breathing waveform diagram is sent to the mobile terminal through the data output module.

It should be noted that, considering that after the signals collected by the snore collecting device 201 and the exhalation pressure sensing device 202 are subjected to signal processing, the two sets of digital-to-analog conversion modules perform digital-to-analog conversion on the two sets of waveform data, and then transmit the two sets of waveform data to the central processing unit, when the two sets of waveform data are obtained by adopting the beam forming technology, if the audio data collected by the snore collecting device 201 are directly subjected to digital-to-analog conversion after the sound pressure is obtained by adopting the traditional method, the problem that the waveform data formed by the two frequency points float is large will occur, as shown in fig. 5, the waveform data appear by superposition after the traditional sound pressure conversion, in the figure, 1 is the waveform data obtained by the snore collecting device 201, 2 is the waveform data obtained by the exhalation pressure sensing device 202, and a is a floating graph of the two segments of waveform data.
Therefore, when the snore collecting device 201 adopts the independent signal processing module to process signals, the method comprises the following steps:
s1: collecting snore data;
s2: dividing data into one sample by N points, carrying out Fourier transform and then carrying out frequency domain weighting to obtain weighted amplitude on each frequency;
specifically, weight a:
after the original data is acquired, N points are taken as a window at a time, fourier transformation is carried out on the window, and the amplitude values of the N points on k frequencies are acquired. The calculation method comprises the following steps:
the resulting X (k) is a complex number, X (k) =a k +b k i. A weight is counted for each X (k), and all k values are juxtaposed, so that an array of A weight is obtained.
For example, when we sample 1024 samples, the sampling rate is 44100Hz, then the array-total 512 data, respectively corresponds to
[43.06640625 86.1328125 129.19921875 172.265625...22006.93359375]
The frequencies in the above table have been calculated by specific numerical values, not just indexed. For frequency f we can also demand the set of a weights for frequency f and add it to the original components at each frequency.
The A weight array can be found by a simple formula, and the python code is as follows:
R_a＝((12194.0**2)*np.power(f_vec,4))/(((np.power(f_vec,2)+20.6**2)
*np.sqrt((np.power(f_vec,2)+107.7**2)*(np.power(f_vec,2)+737.9**2))*
(np.power (f_vec, 2) +12194.0 ×2))) # calculate the a-count weight
A=20×np.log10 (r_a) +2.0# is converted into decibels
Where f_vec is an f-value array.
The results are as follows
[-3.30874258e+01 -2.12872397e+01 -1.57763197e+01 -1.24243792e+01...-1.05872012e+01]

SPLA(k)
The RMS value of a window is calculated according to pasmodic's theorem. Inner a k And b k The amplitudes of the real and imaginary parts of each sample point after fourier transformation, respectively.
In the algorithm, use can be made of
It is easy to understand that the weighting formula is replaced by the weighting formula;
s3: performing time weighing, and adopting the prior art;
s4: the weighted sound pressure level is calculated.

The data can be effectively recorded to prevent the data from being lost by storing the data to the cloud, and meanwhile, a plurality of devices can access the recorded data together.
The rest of the structure is the same as in example 1.
It should be noted that, before the WiFi connection module provided by the present invention transmits data to the cloud for storage, the method further includes the following steps:
s1: integrating the breathing information of different time periods, compressing the data required to be transmitted in different time periods in a segmented manner to form a multi-segment transmission file, for example, dividing sleep 12H into 4 segments, and compressing to form the data required to be transmitted in 4 segments, namely 0-3, 3-6, 6-9 and 9-12;
s2: performing check authority control on the transmission file, and adding a mapping key;
the added authority access control can provide a safer, more flexible and dynamic access authorization mechanism, so that the security and the reliability of the authorization mechanism are improved. The WiFi connection module firstly establishes a mapping relation between different time period authority information requirements and access authorities: "rights information requirement→rights subset", rights information requirement is owner of rights subset, and then rights management assigns corresponding grades to rights subset according to different requirements of passing rights detection, which establishes mapping relation between main body and roles: "request- > level", wherein the request is a user of the level, the mapping relation is actually "request- > level- > rights subset".
The allocation of the different time period authority information detection level map is specifically as follows:
taking sleep time divided into 2 sections as an example, namely 0-6 and 6-12; defining different time period authority information detection requirement set to represent U= { U 1 、u 2 Defining a permission level set r= { R } 1 、r 2 }. The allocation procedure is described as follows:
setting a coarse-granularity secondary menu authority set mp= { mP 1 、mP 2 Fine granularity control rights set mp= { cP 1 、cP 2 Workflow rights combination wfP = { wfP 1 、wfP 2 }；
Definition of class R j An effective period T and a task time T;
U-＞R j namely, different authority information is abstracted into a certain level, and mP- > R j Assigning coarse-grained level two menu permissions to level R j Form R j Right set R of (2) j mP＝{R j mP1、R j mP i }；R j cp=cp n wfP and cP e mP, T e T, and finally obtaining the operation full authority set mapping relation corresponding to the level as follows:
R j mP&cP＝R j mP∪R j cP。
mapping relation of authority setting:
so g (g) n (t) has a certain upper limit in the continuous change, belonging to the limit value of the current moment.
Defining a weight value calculation formula:
T＝[αT 1 +(1-α)T 2 ]σ(t)ΔR
wherein alpha E [0,1] is a historical respiratory factor and is used for representing the action of the historical trust degree of authority information of different time periods in the current authority value, deltaR is the authority level change, and the alpha calculation formula is as follows:
in the middle of
Mu E [0,1] as the authority decay rate]The adjustment can be performed according to the time period, and the larger the time period, namely the longer the session time, the slower the overall attenuation of the authority represented by smaller mu.
