Design of Monitoring System of Offshore Current Energy Device Based on Beidou System

Aiming at the problem of offshore data monitoring of a new type of bidirectional direct-drive wave power generation device, we design a monitoring system based on STM32 microcontroller, Beidou communication module GYM2003B, data acquisition module and multiple expansion interfaces. The command server receives the data upload server storage and monitors them on the PC side in real time. The monitoring system can run smoothly on the sea for 30 days. From the offshore test data, it can be seen that the monitoring system completes the realtime monitoring of the operation status of the power generation equipment, and the system operates reliably, the data transmission is accurate, and the data packet reception rate reaches 99.01％.
