Abstract: To realize the real-time vibration monitoring of vibration of mariculture enclosure structure, a real-time vibration monitoring system of the fence aquaculture platform was developed. The system is divided into monitoring equipment and monitoring software. The monitoring device controls the three-axis accelerometer through the microprocessor main board to collect the vibration data of the maricultural enclosure in real-time and transmits it to the monitoring software wirelessly using 4G-DTU. Monitoring software enables real-time visualization, storage and subsequent download analysis of data collected by monitoring devices.To verify the effectiveness of the system, two monitoring nodes were deployed to conduct field tests on the maricultural enclosure platform in Laizhou Bay. The results show that the deployed monitoring nodes can effectively collect the three-axis acceleration data of the maricultural enclosure structure and transmit them to the monitoring software for visualization and storage in real-time. Meanwhile, the subsequent data analysis reveals that the vibration pattern of the maricultural enclosure platform in Laizhou Bay, the main frequency of vibration is about 4Hz, and the vibration values show obvious spatial and temporal differences at different monitoring nodes. The effectiveness of the developed system is proved。
