| titleOfInvention | Acoustic emission signal feature extraction method, acoustic emission signal feature identification device and storage medium |
| abstract | The invention discloses a method for extracting characteristics of an acoustic emission signal, a method for identifying the characteristics of the acoustic emission signal, a device and a storage medium, wherein the method for extracting the characteristics comprises the following steps: acquiring a mine acoustic emission signal; performing CEEMD decomposition on the mine acoustic emission signals to obtain a plurality of corresponding first IMF components; for a plurality of first IMF components, rejecting pseudo components and noise components based on correlation coefficients and permutation entropy; reconstructing the residual first IMF components to obtain a reconstructed signal; EMD decomposition is carried out on the reconstructed signal to obtain a plurality of second IMF components; and selecting t preset second IMF components from the plurality of second IMF components, and calculating the arrangement entropy under the preset scale to form the feature vector. In the characteristic extraction process, not only can the false components and the noise components be effectively removed, but also the sensitive characteristics can be reserved; the method improves the category identification precision of the subsequent mine acoustic emission signals, can correctly and timely identify the surrounding rock acoustic emission signals, and provides a basis for accurate early warning of an acoustic emission monitoring system. |
