Fault Detection and Diagnosis of Mine Hoist Machine Based on RS and SVM

2016 International Symposium on Computer, Consumer and Control (IS3C), 2016
A fault diagnosis method is proposed for the mine hoist machine fault diversity and redundancy of fault data based on Rough Sets (RS) and Support Vector Machine (SVM). RS theory is used to analyze the stator current fault data of mine hoist machine in order to exclude uncertain, duplicate information.
