An Integration of Spectrum Analysis and Attention-based Network for Condition Monitoring of Vibration Components
2022 IEEE International Conference on Prognostics and Health Management (ICPHM)(2022)
Abstract
High reliability of some key components in various engineering systems is crucial to ensure stable performance, safety operation and economic life-cycle management. This requires efficient and effective condition monitoring and predictive maintenance. With the availability of massive sensor data, increasing attention has been paid to data-driven methods for automatic condition recognition and fault diagnosis. This study proposes a lightweight framework combining domain knowledge and deep learning technique. A novel network incorporating 1D convolution module and multi-head self-attention mechanism is designed to receive information from frequency domain by spectrum analysis. Experiments on multiple cases indicate that the developed method is able to achieve the state-of-the-art results and has the potential generality to cover vibration scenarios for different engineering applications.
