Research on the Key Technology of Fishermen Safety Guarantee System

The safety of fishermen on fishing vessels is always at risk due to potential collisions with merchant vessels. The lack of timely information about incoming ships during fishing operations and sleeping can lead to disastrous consequences. This paper proposes a fishermen safety guarantee system that utilizes wearable devices to alert fishermen about the presence of incoming ships. The system involves three terminals: fishing vessel terminal, shore-based terminal, and fishermen terminal. The system utilizes sensor data from bracelets worn by fishermen and an algorithm to analyze the fishermen behavior and evaluate the fishermen defense ability, then combines the fishermen defense ability level and the collision risk level to evaluate fishermen comprehensive risk level. The system adopts the idea of modular design, constructs from the aspects of framework design, architecture, hardware design, software design and modeling methods. This system helps fishermen to be more aware of their surroundings, accurately assess the current encounter stage, and understand their corresponding duties, ultimately reducing the risk of collisions and ensuring the safety of fishermen.
