The invention relates to a state recognition method for high-end numerical control equipment based on multi-source information fusion, and the method comprises the steps: collecting multi-source sensor information of the operation state of the high-end numerical control equipment through an onsite collection sensor, and carrying out the information fusion; obtaining features of the time domain, frequency domain and wavelet domain of a fusion signal, and carrying out the fusion of the extracted time domain features, frequency domain features and wavelet domain features; reconstructing a multi-source multi-domain high-dimensional phase space of the initial features, employing a local linear embedded structure for the dimension reduction, optimizing an intrinsic dimension number, constructingan neighbourhood which can reflect the local linear features of a low-dimensional manifold, and obtaining the low-dimensional manifold changes in a high-dimensional space of the operation state; obtaining low-dimensional sensitive features through the distance criteria, constructing a multiplication similarity of the low-dimensional manifold features, and achieving the recognition of different states. The method can achieve the effective recognition and judgment of the operation state of the numerical control equipment based on real-time monitoring and effective sensing information, and accurately recognizes different stats of the numerical control equipment.
