主 题:Convolutional autoencoder fault detection metro railway turnout
摘 要:Railway turnout is one of the critical equipment of Switch&Crossing(S&C)Systems in railway,related to the train’s safety and operation *** the advancement of intelligent sensors,data-driven fault detection technology for railway turnout has become an important research ***,little research in the literature has investigated the capability of data-driven fault detection technology for metro railway *** paper presents a convolutional autoencoder-based fault detection method for the metro railway turnout considering human field inspection ***,the one-dimensional original time-series signal is converted into a twodimensional image by data pre-processing and 2D ***,a binary classification model based on the convolutional autoencoder is developed to implement fault *** profile and structure information can be captured by processing data as *** performance of our method is evaluated and tested on real-world operational current data in themetro *** results show that the proposedmethod achieves better performance,especially in terms of error rate and specificity,and is robust in practical engineering applications.
