Method and device for reducing vibration signal compressed sensing reconstruction error and storage medium

The embodiment of the invention discloses a method and device for reducing a vibration signal compressed sensing reconstruction error and a storage medium. The method comprises the steps of obtaining a reconstructed vibration signal, an order and a basic solution system of an underdetermined equation; inputting the reconstructed vibration signal and the order into a preset autoregressive model to obtain autoregressive model feature parameters of the autoregressive model; determining a relative residual error of the autoregression model based on the model residue and the model output quantity; and according to the characteristic parameters and the order of the autoregression model and the basic solution system of the underdetermined equation, carrying out relative residual error reduction processing to obtain a new reconstructed vibration signal. By adopting the method, any transformation base does not need to be used, the method is not limited by the lack of sparsity of the vibration signal, the new reconstru
