Design of Low-Power Marine Recovery Beacon Based on Hydrokinetic Power Generation

This paper proposes a low-power marine recovery beacon that integrates dual-mode positioning with Beidou and GPS and LoRa communication technology. It is designed to meet the requirements of low power consumption, high reliability, and the ability to withstand harsh marine environments. The beacon innovatively integrates conductivity detection circuits, pressure sensors, and ocean current power generation devices to achieve automatic positioning upon surfacing and provide continuous energy support. An intelligent communication switching mechanism is designed to combine the advantages of LoRa communication and Beidou short message communication, ensuring efficient and stable transmission of positioning data under various marine conditions. Through optimized low-power circuit design, unique structural design, and carefully selected materials, the device's endurance is extended, enhancing its practicality and reliability.
