A bearing fault diagnosis method based on multi-sensor multi-scale feature fusion

ActiveCN117828531BImprove classification performancecomprehensive diagnosis
A bearing fault diagnosis method based on multi-sensor, multi-scale feature fusion is proposed. The method involves collecting current and vibration signals to create a dataset, which is then augmented and divided into training, validation, and test sets. A multi-scale feature fusion network model is constructed. The signal data in the training set is transformed using Fast Fourier Transform (FFT) to extract features. An attention mechanism is then introduced to adjust the weights. The fused features are processed alternately using self-calibrating convolutions and dilated convolutions, followed by pooling, feature flattening, and fully connected layers. Finally, a classifier outputs the fault classification result. The validation set is input into the model to fine-tune its parameters. Finally, the test set is used for testing, and the results are output. By using multi-source data such as vibration and current signals as input, and leveraging the ability of neural networks to discover hidden patterns in training samples, this method aims to extract multi-scale features from multi-source data and fuse these features to complete the intelligent fault diagnosis process for bearings.
