Summary: Accurate monitoring of mechanical device conditions requires a large number of sensors working together. Existing deep learning models often focus too much on temporal correlations and ignore spatial correlations of multiple sensors. Therefore, a new end-to-end framework named GAT-DAT is proposed to address these deficiencies, by incorporating a deep adaptative transformer and a graph attention network.

Summary: In the industrial big data context, deep neural networks have been widely used for fault classification and remaining useful life (RUL) prediction of mechanical equipment. However, traditional deep learning models neglect the importance of time-frequency domain analysis for rotating machinery and are limited by single-channel information. To solve these problems, a complex domain extension network with multi-channel information fusion is proposed for RUL prediction. The effectiveness of the proposed framework is demonstrated through case studies using run-to-failure datasets, where it outperforms current state-of-the-art methods in terms of prediction accuracy, interpretability, and generalization.

Summary: A tool remaining useful life prediction method is proposed based on a non-homogeneous Poisson process and Weibull proportional hazard model, considering the grinding repair of machine tools during operation. The method builds an intrinsic failure rate model using tool failure data and establishes a WPHM by collecting vibration information during operation. By incorporating tool grinding repair, the NHPP-WPHM under different repair times is established to describe the tool's comprehensive failure rate. The effectiveness of the model is verified by comparing it with actual remaining useful life and another WPHM-based prediction model.

Summary: Accurate remaining useful life (RUL) prediction is crucial for maintaining the safety and reliability of industrial systems. Deep learning based-methods have shown potential in improving prediction accuracy by learning and fusing degradation features from signals. However, these methods often neglect the characteristics of different sensors in the spatial domain. In this paper, we propose an adaptive spatio-temporal graph neural network (ASTGNN) framework that addresses this issue by considering both spatial structures learning and spatio-temporal information fusion.
