Research on Urban Rail Train Passenger Door System Fault Diagnosis Using PCA and Rough Set

摘要

Train passenger door is the key system for operation and maintenance on urban rail train. In this paper, weanalysis passenger door system of urban rail train working process and establish the mathematical model. Firstly, we usethe method of parameter estimation to get physical parameters of doors on different working condition. Then faultdiagnosis experiment is done to train passenger door with principal component analysis and rough set theory. In the end,we verify fault diagnose accuracies under different time settings of opening and closing profile with the test rig.
