Svm based diagnostics on railway turnouts
Splet14. dec. 2014 · This algorithm summarized the typical turnout fault action current curves, established the mapping data sets between the action current curve and turnout fault … SpletThe simulation results indicated that FCM classifier model, based on GAPSO, could effectively classify the faults of the railway turnout. The GAPSO-FCM model could achieve a 97.1% fault diagnosis accuracy rate that showed that the GAPSO-FCM model proposed in this paper had high accuracy.
