A, can be used in the mechanical condition monitoring and fault diagnostic signal with oscillation, sample analysis, temperature monitoring and non-destructive testing inspection is given priority to, other skills or complementary situation. 

  Second, in terms of vibration signal analysis disposal, in addition to the classic statistical analysis, time and frequency domain analysis, time-series model analysis and parameter identification, recently conducted a frequency refining skills again, cepstrum analysis, resonance demodulation analysis, 3d holographic spectrum analysis, axis orbit analysis, and according to the non-stationary signal assumes that the short-time fourier change, Winger spread and wavelet change, etc.

  Three, the development of embedded skills as well as the modern virtual instrument, equipment fault diagnosis and monitoring instrument has began by analog appearance to now according to the computer real-time online monitoring and fault diagnosis system and portable monitoring and analysis system based on microcomputer.
