Fault diagnosis of electric impact drills using thermal imaging

Fault diagnosis enables to make savings related to maintenance. The presented work describes fault diagnosis method based on analysis of thermal images. An original method for feature extraction of thermal images BCAoID (Binarized Common Areas of Image Differences) is proposed. Thermal images of three electric impact drills (EID) were used for an analysis: healthy EID, EID with faulty fan (10 broken fan blades), EID with damaged gear train....
