    • Abstract
  • According to fault features of elevator brake,the paper put forward a fault diagnosis method of elevator brake based on LS-SVM.The method can detect signal of brake clearance of elevator brake in brake process and extract feature vectors of fault signal by use of wavelet packet analysis,and then realize faults diagnosis of elevator brake with(LS-SVM.) The experiment results showed that the method can diagnose fault of braking system incorrectly and avoid fault effectively.
