Abstract
With the advancement of Industry 4.0, intelligent manufacturing has become the core direction for the transformation and upgrading of the manufacturing industry, while predictive maintenance and health management (PHM) have gained significant attention as a key technology to ensure the efficient and stable operation of intelligent production systems. This study aims to construct a PHM system suitable for complex manufacturing environments by integrating advanced data-driven approaches with domain knowledge. Based on multi-source heterogeneous sensor data, a hybrid model combining deep learning and signal processing is proposed, which effectively extracts operational state features of equipment and achieves precise predictions. Meanwhile, Bayesian networks are introduced to optimize uncertainty analysis, thereby enhancing the reliability of prediction results. Experimental results demonstrate that this method exhibits superior performance in various typical industrial scenarios, with a prediction accuracy improvement of over 15% compared to traditional methods, along with strong generalization capabilities. Additionally, a real-time monitoring and decision support module has been developed, providing intelligent recommendations to maintenance personnel and significantly reducing equipment maintenance costs and downtime. The primary innovation of this research lies in the organic combination of deep learning's nonlinear modeling capabilities with the prior advantages of domain knowledge, overcoming the limitations of traditional methods under complex working conditions and offering new insights and technical support for equipment health management in intelligent manufacturing..
