摘要

PROBLEM TO BE SOLVED: To provide an unmanned monitoring buoy for drifting materials, a monitoring system for drifting materials and a method thereof which can detect the position of the drifting materials by facilitating collection of the drifting materials such as heavy oil on the water and automatically tracking by detecting the position of the drifting materials in order to reduce the effect on the natural environment and local economy due to oil spill incident such as heavy oil, and can detect the data of hydrographical/meteorological phenomenon of the drifting water area of the drifting materials and transmit the data to the base station in real time.;SOLUTION: The unmanned monitoring buoy (10) for drifting materials is put in a water area having the drifting materials (Fo), and automatically repeats surfacing and downwelling in the water area. The monitoring buoy detects the existence or non-existence and the position of the drifting materials (Fo) on the water surface part when it is under the water surface. After detecting, the monitoring buoy floats toward the position of the drifting material (Fo) to be detected, and sends the position information and the data of hydrographical/meteorological phenomenon or the like when floating in the area of the drifting materials (Fo) on the water surface.;COPYRIGHT: (C)2008,JPO&INPIT
