Aiming at the current problem of using a single scale convolution kernel in time domain signal recognition based on convolutional neural networks,which leads to insufficient feature extraction,and the selection of hyperparameters is mostly based on artificial experience,a multi-scale convolution neural network (MCNN) recognition method is proposed.First,directly using the original time domain signal as input not only effectively preserves the original signal characteristics,but also does not require people's understanding and experience of the fault mechanism,as well as professional knowledge of signal processing.Then,the multi-scale convolutional neural network is used to learn the signal characteristics,and particle swarm optimization (PSO) is introduced to seek the optimal scale information.Finally,the performance of the model is verified using a rolling bearing dataset and compared with other models.The experiment results show that the average recognition accuracy reaches 99.45%,which is superior to other models,proving the feasibility of the proposed method.
