| Abstract: | Bacause of the measurement methods being used for fault diagnosis of rolling bearing in railway transportation have many deficiencies which includes misinterpretation, leakage report and low monitoring efficiency. Thus this paper presents a new kind of circuit design for fault diagnosis of rolling Bearing based on advanced DSP technology. The design can adapt properly modern high- speed train and get rid of response lag time and multi- phase noise. |
