In a preferred embodiment, as shown in fig. 2, the monitoring device 1 includes a data acquisition processing unit 15, the data acquisition processing unit 15 is connected to the acquisition unit 11;
the data acquisition processing unit 15 is used for providing a preset algorithm to identify the bowel sound data acquired by the acquisition unit 11, so as to classify and store the acquired bowel sound data.
In the technical scheme, the data acquisition and processing unit 15 mainly controls the acquisition unit 11 to convert the analog signals of the acquired bowel sound data into digital signals, and after amplification processing, the characteristics of the bowel sound data are identified by adopting a preset algorithm including an ambient noise removing algorithm and a bowel sound characteristic algorithm, wherein the characteristics include frequency and loudness;
it should be noted that the bowel sound feature algorithm is an algorithm designed mainly for the frequency and loudness in bowel sounds.
The following specific embodiment is provided for noise removal and bowel sound data feature extraction, wherein the algorithm execution sequence is that firstly, denoising processing is performed on the acquired bowel sound data through a first preset algorithm, namely noise removal, and then feature extraction is performed on the denoised bowel sound data through a second preset algorithm, namely bowel sound feature algorithm, and the specific embodiment is as follows:
carrying out denoising process on the collected borborygmus data:
the basic principle adopts audio self-adaptive active noise reduction: the four-way sensor 111 collects environmental noise, namely reference noise, and collects bowel sounds, namely superposition of bowel sound data signals and noise, and the three-way sensor has the same working principle and is used as a way of description of the same class;
according to the self-adaptive VSSLMS algorithm, the noise reduction system utilizes the reference noise of one path to offset the noise of the other path and outputs a useful signal. Compared with passive noise reduction, active noise reduction can adjust parameters of the active noise reduction according to changes of input signals, and noise is removed more effectively. Compared with a classical filter (high-pass, low-pass and the like), the adaptive filter of the active noise reduction system can remove noise with the same frequency as a useful signal;
the algorithm implements a general expression for the adaptive active noise reduction system error:
e(n)=d(n)-y(n) (1)
y (n) is the signal associated with background noise x (n), then
e(n)=d(n)-w(n)xT(n) (2)
Wherein w (n) ═ w0,w1,....,wL],x(n)=[x(n),x(n-1),....,x(n-L)]And L denotes the order of the filter. y (n) can be calculated by selecting the optimal weight w (n) of the optimal FIR wiener filter, i.e.
Wherein x (n-i) is obtained by delaying x (n).
Fig. 7 is a schematic block diagram of a general prototype of the adaptive algorithm. Where s (n) is the desired signal and v (n) is the background noise. The desired signal d (n), i.e. the signal to be processed, is composed of the useful signal s (n) and the background noise v (n), and s (n) and v (n) are uncorrelated. The input signal x (n) is actually the reference signal s' (n) associated with s (n) in d (n). Equation (1) can then be converted into:
e(n)=(s(n)+v(n))-w(n)s′(n)T
wherein, s' (n)T=[s′(n),s′(n-1),...s′(n-L)]T。
As shown in FIG. 8, which is a block diagram of the adaptive noise cancellation principle based on the wiener filter, equation (1) can be converted into
e(n)=(s(n)+v(n))-w(n)v′(n)T
Where s (n) and v (n) are uncorrelated, v' (n)T=[v′(n),v′(n-1),...,v′(n-L)]T. The input signal x (n) is actually the reference signal v' (n) associated with v (n) in d (n).
In the noise cancellation system e (n) is substantially the useful signal s' (n) after the noise is cancelled by the signal to be processed. The useful signal is not identical to the useful signal s (n) in the signal source, because the coefficients passing through the filter can only approximate the optimal solution, and the signal output by the processing can only approximate the original useful signal.
The collected signals are subjected to noise cancellation by using a VSSLMS algorithm. The algorithm steps of fig. 7 and 8 are shown in table 1 below.
TABLE 1 VSSLMS Algorithm step comparison
Wherein s isT=[s(n),s(n-1),...s(n-L)]T,vT=[v(n),v(n-1),...,v(n-L)]T。
It can thus be seen that: the VSSLMS algorithm is used in a noise cancellation system, and actually performs role exchange between a signal source and a noise source. The overall algorithm steps are not changed greatly, only the input signals are different, and the interior of the filter is not changed. The algorithm of noise reduction is simple to calculate and easy to realize.
The process of extracting the characteristics of the denoised bowel sound data comprises the following steps:
according to the basic principle, in order to realize rapid and accurate analysis of bowel sound, frequency spectrum analysis is carried out on bowel sound signals, a db6 wavelet function with high energy concentration and good local characteristics is used as a wavelet packet mother function, an optimal basis suitable for bowel sound signal analysis is selected, 4-layer wavelet packet decomposition is carried out on different types of bowel sound signals, and a wavelet packet coefficient of the optimal basis is obtained. And extracting the normalized energy of the optimal fundamental frequency band as a feature vector of the bowel sound according to the equivalent relation of the wavelet packet coefficient and the signal energy on the time domain. And calculating the separability measure mean value of various bowel sound characteristics by adopting a category separability criterion.
The specific algorithm is executed as follows:
the selection of the wavelet packet mother function directly influences the analysis precision of signals, and the time-frequency analysis of the bowel sounding signals requires that the time locality of the wavelet packet mother function is good and the energy concentration is high. The Daubechies wavelet has good local characteristics, can well extract useful signal components in various transient waveforms, and finally selects db6 tightly-supported orthogonal wavelets as wavelet packet mother functions through repeated tests and comparison.
The support region in the wavelet function ψ (t) and the scale function φ (t) corresponding to the db6 wavelet is 11, and the vanishing moment order of ψ (t) is 6. The db6 wavelet has no explicit expression, and its square modulus of the transfer function h is given by the equation (1):
wherein,are binomial coefficients.
Wavelet packet algorithm
On the basis of wavelet multi-resolution analysis theory, a scale function phi (t) is recorded as u0(t) the wavelet function ψ (t) is denoted as u1(t), then from the two-scale equation:
defined set of functions un(t)}n∈ZIs called by u0(t) phi (t), where h (k), g (k) are conjugate filter coefficients.
Feature extraction
From Parseval equation:
it can be known that the wavelet transform coefficient Cj,kThe dimension with energy can be used for energy analysis. Since the bowel sound signals of different heart diseases have different energy distributions in the respective decomposition frequency bands, the energy of the wavelet packet coefficient can be used as the feature vector of the bowel sound signal.
Category separability criterion
Feature set { a) composed for same class of featuresiI is 1, 2, … k, and its inter-class distance is one of the important indicators for measuring pattern separability. The square of the intra-class distance is defined as the mean square of the distance between the feature vectors in the set:
for two types of feature sets { a }i,i=1,2,…kaAnd { b }andj,j=1,2,…kbWherein a isi∈ class A, bj∈ B, the square of the distance between class A and class B is:
it can be seen that if a certain feature extraction means that the inter-class distance can be made larger and the intra-class distance is made smaller, the extraction method is said to be good. Unifying the intra-class distance and the inter-class distance, and defining the separability measure as follows:
it can be used as an index for measuring the separability between different classes. J. the design is a squareA,BThe larger the size, the better the separability between class A and class B; j. the design is a squareA,BThe smaller the size, the more between class A and class BThe poorer the separability.
