Real-time monitoring of ship bearing signals can effectively improve the safety and reliability of ship operation. This paper proposes a ship bearing signal monitoring system, designs the hardware structure framework of the monitoring system, expounds the functional realization principle of each module, and gives the installation structure design scheme of the bearing sensor. The vibration signals of a certain type of ship bearing under different states are tested, and the types and basic characteristics of abnormal signals are analyzed. On this basis, the process of feature extraction and classification of ship bearing signals based on deep learning is proposed, and the realization process of self-attention mechanism is discussed. The ship bearing signal monitoring system proposed in this paper can not only ensure high real-time performance, but also accurately distinguish the bearing vibration signal.
