Title:
DEVICE STATE DETECTION METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/029229
Kind Code:
A1
Abstract:
In a device state detection method and a related apparatus provided in the present application, a data processing device enables an auto-encoder to be combined with a plurality of recurrent neural networks, respectively reconstructs, by means of the auto-encoder, a plurality of state feature sets of a device to be detected, and according to differences between the plurality of state feature sets and the respective reconstructed feature sets, determines a health state of the device to be detected. Because features to be reconstructed of the auto-encoder are obtained by respectively performing feature mining by the plurality of recurrent neural networks on a plurality of encoding sequences having different feature scales, device health state-related information contained in a device state sequence can be fully explored, so as to achieve the purpose of improving the detection precision.
