Looseness Identification of Track Fasteners Based on Ultra-Weak FBG Sensing Technology and Convolutional Autoencoder Network
Changes in the geological environment and track wear, and deterioration of train bogies may read more lead to the looseness of subway fasteners.Identifying loose fasteners randomly distributed along the subway line is of great significance to avoid train derailment.This paper presents a convolutional autoencoder (CAE) network-based method for ident
