Aiming at the difficulty of fault identification caused by manual extraction of fault features of rotating machinery,a one-dimensional multi-scaleconvolutional auto-encoder fault diagnosis model is proposed,based on the standard convolutional *** this model,the parallel convolutional and deconvolutionalkernels of different scales are used to extract the features from the input signal and reconstruct the input signal;then the feature map extracted by multi-scale convolutional kernels is used as the input of the classifier;and finally the parameters of the whole model are fine-tuned using labeled *** on one set of simulation fault data and two sets of rolling bearing fault data are conducted to validate the proposed *** results show that the model can achieve 99.75%,99.3%and 100%diagnostic accuracy,*** addition,the diagnostic accuracy and reconstruction error of the one-dimensional multi-scaleconvolutional auto-encoder are compared with traditional machine learning,convolutional neural networks and a traditional convolutional *** final results show that the proposed model has a better recognition effect for rolling bearing fault data.
