Ocean buoys are used as a new high-tech monitoring tool, It can realize the continuous, real-time uninterrupted automatic monitoring of water quality, meteorology, ecology and other parameters in the sea area, even in a very harsh environment, other monitoring methods can not work, the ocean buoy can still continue to work effectively. It is used in various dredging projects, sand extraction projects, port expansion, waterway dredging, waterway warning and aquaculture industry.
Ocean buoy indicators indicate the direction, limits and obstructions of the waterway, including river crossing markers, coastal markers, guide markers, transition guides, end-to-end guides, side markers, left and right navigation markers, position markers, flood markers and bridge culvert markers. It is a manual sign that helps ships navigate, locate and mark obstructions and warnings. The navigation standard distribution shall simply and clearly indicate the safe, economical and convenient waterways for ships according to the specific navigation conditions of rivers, rivers, lakes and reservoirs.
Marine observatories have been set up along the coast and on islands to measure wave height, current, SST, tide level, wind velocity, hydrometeorological elements such as barometric pressure,
if we could use these infromation, it can bring more convenience to people. For example, Knowing the area of strong winds and waves, you can avoid the tragedy of shipwrecking and death when sailing; Knowing the direction of the current, we will go as far as possible when sailing, so as to save sailing time and energy consumption; Knowing the abnormal increase in tide level, we can prepare for emergencies in time and try to reduce losses to a very low level in the event of a disaster. what's more, The information obtained by the Marine Observatory is also indispensable for offshore engineering construction and marine scientific research.
In general, the main structure of the marine monitoring buoy is composed of floating body, mast, anchor system and counterweight, and the functional module is mainly composed of power supply, communication control, sensor and so on. The water mast part is mainly used to carry solar panels, meteorological sensors and communication interruptions; The underwater section is equipped with hydrological water quality sensors that measure hydrology (parameters such as waves, currents, temperature and salt depth) and water quality (chlorophyll, algae, and the concentration of various related substances dissolved in seawater).The signal generated by each sensor is automatically processed by the instrument, sent by the transmitter at regular intervals, and the ground receiving station processes the received signal to obtain the information that people need. Some buoys are built far away from land and send the signal to the satellite, then the satellite transmits the signal to the ground receiving station.
