Health Assessment and Fault Warning Method for Elevator Door System

The elevator door is the most malfunctioning part of an elevator. A regular health assessment of the elevator door system can help elevator maintenance personnel detect abnormalities in time. In this paper, we first sort out common elevator door system faults and then propose a method of elevator door health assessment and fault warning based on the Gaussian Mixture Model. Finally, we design a series of elevator door failure experiments and use experimental data to verify the effectiveness of the proposed method.
