  • Unmanned drifting substance monitoring buoy, drifting substance monitoring system, and drifting substance monitoring method
    Patent number: 8983780
    Abstract: An unmanned drifting substance monitoring buoy (10) is thrown into a water area where a drifting substance is present, thereby tracking and monitoring the drifting substance. The unmanned drifting substance monitoring buoy (10) detects, by a detecting section, a relative location of the drifting substance on the water surface with respect to the unmanned drifting substance monitoring buoy (10), and measures, by a measuring section, directions and strengths of a wind and a tidal current. Then, the unmanned drifting substance monitoring buoy (10) tracks the drifting substance by adjusting, based on the relative location of the drifting substance detected by the detecting section and on the directions and the strengths of the wind and the tidal current measured by the measuring section, a surface area and a direction of a sail (13) by an adjusting section.
