Therefore, the detection piece 61 is obliquely arranged, the muscle tone signal detection sensor in the detection piece is positioned in the middle of the detection piece, when the rear side of the chest belt is stretched, the upper end of the detection piece can be deviated to the outside, so that the muscle tone signal detection sensor in the middle is partially deviated and still corresponds to the position of muscle, the detection point of the muscle tone signal detection sensor can be always aligned to the position of the muscle to be detected, and the accuracy of signal detection is ensured. The adopted muscle sound signal detection sensor is a piezoelectric acceleration sensor, and the sensor has high sensitivity, large sensitive area and good anti-interference performance.
Compared with myoelectric signals, myoelectric signals still have higher accuracy in muscle contraction fatigue. Due to the propagation properties of the muscle tone signal, the sensor does not need to be fixed in some specific position, and may not even directly contact the skin, and the muscle tone signal can also be picked up at the tip of the exercising muscle. The influence of the body surface impedance on the muscle sound signal is small, the interference of an external electric field is small, and the detection accuracy is higher. This scheme combines together chicken chest detection device and the utilization of flesh sound signal for improve the degree of accuracy that chicken chest signal detected.

The fastening band 4 may be of an open type and may be connected to form a loop shape by a buckle or a hook and loop fastener, and is not particularly limited in particular use.
When the chest belt 2 is worn, the chest belt 2 can be worn on the upper body through the shoulder straps 1 to prevent the chest belt 2 from falling off, but when the human body bends the waist and the back, the shoulder extends forwards to lift the chest belt 2 upwards. Because the chest strap 2 is attached to the human body, once the chest strap is pulled up, the chest strap is difficult to return by itself, so that the detection piece cannot effectively detect the muscle tone signal, and the judgment is inaccurate.
The fastening belt 4 can be arranged at the waist position, and due to the limitation of human bones, the fastening belt 4 can return to the waist position even after the human body moves in a bow-waist manner. Therefore, by arranging the fastening belt 4 below the chest belt 2, the position of the detection piece 61 can be better ensured, and the detection accuracy is ensured, so that the correction effect of the chicken chest is improved.

step 2, the pressure sensor 32 detects the pressure, if the pressure is not at the set value, a signal is sent to the processor, the processor controls the air inlet and outlet control motor on the front side of the chest belt 2 to act, and opens the control valve to inflate the orthopedic air bag 31, so that the orthopedic air bag 31 generates the set pressure value;
step 3, when the pressure value is at a set value, the detecting sheet at the rear side of the chest belt 2 starts to collect muscle sound signals, when the back of a wearer acts, the muscle sound signals can change, and then the signals are sent to a matched preposed conditioning circuit board to be subjected to signal denoising and amplification processing;
step 4, processing the signals processed by the front-end circuit by the acquisition card to convert the signals into digital muscle sound signals which can be identified by a computer; the digital muscle sound signals are sent to the processor, and after being processed by programs such as feature extraction, feature dimensionality reduction and mode identification, the processor adopts wavelet transformation and a VPMCD algorithm to identify whether the chest of the wearer is in an expansion state;
step 5, when the chest is judged to be in a non-expansion state, the processor sends execution information to the signal execution module, and the signal execution module acts to inflate the orthopedic air bag 31 and the back air bag belt 7 to force the chest of the wearer to expand; when the chest of the user is judged to be in an expansion state, the processor controls the air inlet and outlet control motor on the front side of the chest belt 2 to act, so that the orthopedic air bag 31 is reduced to a set pressure value.
The VPMCD method is a pattern recognition method based on a variable prediction model, and in theory, the correlations between characteristic variables in different classes are different. In the problem of pattern recognition of human body surface muscle sound signals, a group of characteristic quantities X ═ X is adopted1,X2,···,Xp]A category is described in which a characteristic value X is present in different categories of back posturesiBy other characteristic values XjThe influence of (j ≠ i) is also different. They have a possibly one-to-one relationship X with each other1＝f(X2) Also, it isPossibly one-to-many relationship X1＝f(X2,X3DEG.C). In order to identify different classes of motion patterns, a mathematical Model capable of expressing the intrinsic relationship between characteristic variables, namely a Variable Predictive Model (VPM), needs to be established by using training samples. And predicting the test samples through the prediction models, and classifying by taking the minimum sum of squares of prediction errors of each class as a discriminant function.
The processor adopts wavelet transformation and VPMCD algorithm to identify chest expansion and non-expansion states, and the method comprises the following steps:
s1, collecting samples of five actions of chest expansion, arch back, left lateral bending, right lateral bending and chest retraction, and obtaining a prediction model VPM by using a VPMCD algorithmtraining(ii) a The prediction model VPMtrainingThe method comprises the steps of testing a program stored in a system in advance to serve as an original matching action type;
s2, carrying out sEMG signal acquisition on the back action by the electrode plate;
and S3, carrying out three-layer wavelet decomposition on the collected sEMG signal by using a wavelet basis function to obtain a wavelet coefficient of each frequency band. The meaning formula of the wavelet transform is shown as formula (1):
wherein f (t) ∈ L2(R)，L2And (R) is a function space formed by a square integrable function on R. ψ (t) is a base or mother wavelet, a is a scale factor, and b is a shift factor.
Then expressing the signal by linear combination of wavelet bases with different scales and different translations; as shown in formula (2):
wherein,the coefficients of each term are called wavelet coefficients, AI(t)、Di(t) low and high frequency components of the I-th stage, respectively, waI、wdiRespectively representing the low-frequency wavelet coefficient and the high-frequency wavelet coefficient of the ith level;
and S4, extracting the wavelet coefficient modulus maximum value of each sub-band after wavelet decomposition as a feature vector. Thus, a characteristic value matrix of each category is obtained, and the internal relevance between the characteristic values can be verified by adopting a cross-correlation analysis method during the test;
s5, using the trained prediction model VPMtrainingAnd classifying and identifying the characteristic value matrix, and determining various types of back actions according to the data result of the VPMCD classifier.
As can be seen from the graph 5, the chest expansion state is identified by adopting the wavelet transform and the VPMCD algorithm, the accuracy is higher, and the method establishes a variable prediction model by a parameter estimation method, so that the selection problem and the iterative process of ANN structures and types are avoided. In addition, the model type and the parameter selection depend on the minimum sum of squares of prediction errors of the predicted value and the actual value, so that the dependence on the prior knowledge is avoided, and the method is more objective. Therefore, the method has better VPMCD training capability and classification performance, and is an effective and reliable surface muscle sound signal pattern recognition method.
