Signal processing method is one of important technological bases in the existing fault diagnosis of mechanical equipment, and the degree of accuracy of analysis results is the key factor for whether the diagnosis is successful. Research on spectral analysis is one of the existing main development directions. The digital signal processing is basically to solve signal processing problems from two aspects, including that: the first is time domain method (namely digital filtering; the second is frequency domain method (namely spectral analysis). The paper has mainly introduced discrete Fourier transform and fast Fourier transform; made an in-depth research and study form foundation, and mastered the key of FFT algorithm by researching DFT and FFT algorithms. With the study of DSP chip operating principle and development environment, the sample commissioning of CCS and software simulation have been grasped, and the real-time spectral analysis for signal on the DSP clip is realized.
