VESSEL SUPERVISORY SYSTEM

摘要

PURPOSE: A ship monitoring system is provided to accurately calculate a height of an object by changing a position of a camera and a laser according to a change of a sea surface due to difference of tide. CONSTITUTION: A floating body(211) is installed in a sea surface, and is moved according to a change of the sea surface. A supporting body(212) is attached to a top part of the floating body, and is moved according to a change of the floating body. A bottom supporting member(213) surrounds the floating body. A hole is formed in the center of the bottom supporting member in order to move the supporting body according to inflow and outflow of seawater. A control part(214) is attached to the supporting body, measures a width or a height of an object coming from a long distance, generates an alarm according to the measuring result, and includes a laser part which irradiates a laser beam to the object. The laser part receives the laser beam reflected from the object, includes a light receiving part and a light emitting part, and controls intensity of the laser beam through increase/decrease of the number of light emitting parts.
