The application discloses a pyramid type time convolution network structure and a diagnosis method for real-time bearing fault diagnosis, relates to the technical field of mechanical part fault diagnosis, and is composed of four parts of data input, network segment 1, network segment 2 and result output. The data input part is used for preprocessing original data and transmitting the original data to the network segment 1, the network training is performed through the connection mode of neurons in the network segment 1, and the output prediction sequence is transmitted to the network segment 2. The network segment 2 classifies the prediction sequence to obtain different fault types and transmits the fault types to the result output part. The result output part is used for training and diagnosis, and finally outputs a diagnosis result. The pyramid type time convolution neural network structure and the diagnosis method can fuse different sensor data, have small network parameters, require less memory resources during network training, and can perform real-time fault diagnosis.

This invention relates to noise reduction methods, and more particularly to a lightweight multi-axis Transformer single-channel noise reduction method. It can fully extract the latent time-frequency features of speech signals. A multi-head dynamic local self-attention module is employed to efficiently extract local features. The proposed method has fewer network parameters and lower computational cost, while remaining competitive with state-of-the-art methods in terms of speech signal quality and intelligibility. It can fully extract the latent time-frequency features of speech signals, effectively reducing computer resource consumption. Hint blocks are used to help the model better learn frequency feature information.
