Daubechies12 Wavelet in Analyzing the Current of Anode Rod
Gaoqi Xiao · 2016
This paper is concerned about the rod current of aluminum reduction cell.Daubechies12 wavelet was adapted to analyze time-frequency characteristics of anode current collected which was carried on the pretreatment, and the experimental results verified the effectiveness of the proposed scheme, compared with actual working conditions.After using Daubechies12 wavelet, we can get the magnetic fluid fluctuation frequency.In this way, we obtain the key factors of fault diagnosis.This research can make preparations for the follow-up study of the fault diagnosis of aluminum electrolysis.
