Signal acquisition and data processing are chiefly matter of format knowledge base of rotating machine fault diagnosis. Vibration analysis technology is a common method of fault diagnosis in the kind of fault machine signal. FFT and wavelet transform are important mathematical tool when vibration signal is analyzed in real time and continuously. At the paper ,a data base about rotating fault relationship between eigenvector fault type was set up, and original knowledge base was provide for fault diagnosis decision table based on rough sets.
