Fishermen face significant risks at sea without effective safety measures, including harsh conditions, unpredictable weather, and health emergencies. This system uses RFID technology integrated into a wristwatch to offer real-time monitoring and support, enhancing fishermen's safety and well-being. By addressing these challenges, the system aims to reduce the risks associated with their perilous occupation. Method: This safety system employs GSM communication along with various environmental and health monitoring sensors to keep track of the fisherman's environment and health conditions. The RFID wristwatch is equipped with sensors that continuously monitor conditions such as temperature, humidity, water quality, heart rate, body temperature, and consciousness based on body movement. Data is transmitted via GSM to a central monitoring station, allowing for timely interventions and alerts when anomalies are detected. An intelligent switching mechanism optimizes communication by automatically switching from RF signals to acoustic signals depending on whether the fisherman is on the surface or underwater. Acoustic signals travel longer distances without disturbance underwater but are easily affected by objects in the air, while RF signals travel easily in the air but fade underwater due to water constituents. This switching ensures robust connectivity, with signals reaching the central station through a buoyant relay unit regardless of the fisherman's location. Results: The system facilitates real-time monitoring of environmental conditions and vital signs, enabling timely interventions and alerts. The intelligent switching mechanism ensures that communication is effectively maintained, allowing signals to reach the central monitoring station in various environments, thereby safeguarding the fisherman's safety. Conclusion: This comprehensive safety system, with its robust connectivity and AI-powered assistance module, significantly enhances the safety and survival chances of fishermen. By continuously monitoring their health and surroundings, advanced technological solutions ensure the well-being of fishermen both at sea and underwater.
