The fault signal is a non-stationary and nonlinear signal, and because of the complexity of the field environment, the fault signal often has a lot of noise interference. In order to reduce the noise interference to the greatest extent, a feature extraction method based on digital filter and the local mean decomposition is proposed. Firstly, the Fourier transform is used to obtain the dominant frequency...
Considering the complexity of aluminum electrolysis process, transfer function model of single anode of aluminum electrolytic cell was obtained by means of system identification. Firstly, the frequency characteristics of single anode were measured and analyzed. Secondly, transfer function model was built. Finally, the measured frequency characteristic data was identified to be a high-precision transfer...
An online detecting system of aluminum electrolytic anode current is designed. This system adopts the architecture of state machine based on queue to solve a problem of real time response between data communication and human-computer interaction by using multithreading. It can detect real-time current distribution of anode rod and to deal with abnormal alarm. Under each work condition of aluminum...
The anode current is a very important parameter in the aluminum electrolysis production. However at present, manual measurement is still being used in the aluminum industrial. There are some shortcomings, such as low measurement precision, data lag, etc. This approach can't meet the requirements of the modern management and production for aluminum electrolysis. Based on the principle of anode rod...
