Autonomous navigation type marine buoy and marine information system using the same

An autonomous navigation type marine buoy comprising:

• a buoy body consisting of a floating body;
• at least one internal sensor provided in the buoy body;
• a detection unit that receives a GPS signal and information of the internal sensor;
• an on-water exploration unit that explores a state on a sea;
• an underwater exploration unit that explores a state under the sea;
• a determination unit that creates a navigation plan for the buoy body along a target route set based on position information of the buoy body detected by the detection unit and chart information;
• a propulsion unit that propels the buoy body;
• a navigation control unit that performs drive control of the propulsion unit so that the buoy body navigates according to the navigation plan generated by the determination unit;
• a power generation unit that generates power using natural energy;
• a power storage unit that stores electricity generated by the power generation unit and supplies electricity to a necessary location in the buoy body;
• a communication unit that communicates with an outside;
• an emergency signal unit that receives a distress signal and specifies a transmission position of the distress signal;
• and
• an evacuation room that accommodates a victim,
• wherein the autonomous navigation type marine buoy has
• an autonomous navigation mode of performing autonomous navigation to a set position on the sea,
• a home position mode of autonomously holding a home position at the set position on the sea, and
• a rescue mode of performing autonomous navigation to the transmission position of the distress signal on the sea when the distress signal is received.
