Speech Title: Edge Analytics for Bearing Fault Detection based on Convolution Neural Network
Abstract: Advanced technologies of Sensorics and Internet of Things enable realtime data analytics based on multiple sensors covering the target industrial production system and its manufacturing processes. The rolling bearings fault detection problem is one of the most urgent and could be solved using convolution neural networks and edge artificial intelligence (edge AI) devices. The limitations of the hardware platform must be taken into account to achieve maximum performance. In this paper, we analyze efficient CNN architecture for bearings fault detection that is able to process data in real-time on edge AI devices. We observe that the accuracy of CNN is unsatisfactory for practical use, and better accuracy is possible with increasing the number of bearings in the training dataset. The invited speech is prepared together with PhD students Valentin, Perminov and Vladislav Ermakov from PetrSU. The reported study was funded from Russian Fund for Basic Research according to Research Project No. 19-07-01027.
