Description

Deep sea condition monitoring system and buoy based on space satellite Technical Field The invention relates to the technical field of sea condition monitoring, in particular to a deep sea condition monitoring system and buoy based on a space satellite. Background Buoy, a kind of navigation mark floating on water surface, is anchored in the designated position to mark the range of the navigation channel, to indicate the shoal, the navigation obstacle or to indicate the special purpose of the navigation mark on water surface. The buoys are the most in number among the beacons, and are widely used and arranged at places where fixed beacons are difficult or inconvenient to set up. Buoys, whose function is to mark the channel shoal or obstacles endangering the navigation safety. The buoy provided with the lamp is called a lamp buoy and is used for assisting navigation into a signal buoy in a navigation water area at night and day. Some buoys are also equipped with radar transponders, radio beacons, fog warning signals, marine survey instruments, etc. Compared with a sea ship, the size and the mass of the buoy are much smaller, when the ship passes near the buoy at a certain speed, the buoy can be subjected to great attractive force and collide with the ship body, and the buoy can be seriously askew or even sink due to water entering the inner cabin of the buoy. Sea conditions are also known as sea surface conditions and sea conditions, and refer to the appearance characteristics of the sea caused by stormy waves and swells in marine hydrologic observation.
