Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] see figure 1 , figure 1 It is a flowchart of the present invention. Concrete implementation steps of the present invention are as follows:
[0019] (1) Apply EMD (Empirical Mode Decomposition, EMD) to decompose the composite fault signal into several IMF components. The EMD method is a new signal time-frequency analysis method. It uses the change of the internal time scale of the signal to analyze the energy and frequency, and can adaptively decompose the nonlinear and non-stationary signal into a limited number of linear and steady-state intrinsic mode function components (Intrinsic Mode Function , referred to as IMF) IMF1, IMF2, IMF3..., IMFn, such that different eigenmode components reflect information of different frequency bands. The composite fault has multiple fault characteristics corresponding to different fault frequencie...
