Ocean buoy is a marine hydrological and meteorological observation station, which is composed of the anchor in the sea. It can in accordance with the provisions of the requirements of long-term, continuously for marine scientific research, and offshore oil (gas) development, port construction and national defense construction collect required oceanographic and meteorological data, especially to collect data of survey ship is difficult to collect adverse weather and sea conditions.

The observed data from the coastal and Sea Island stations can only reflect the situation of coastal waters and islands, which can not play a role in ocean navigation. And the establishment of ocean buoy can solve this problem. Ocean buoy is an unmanned automated ocean observation station, it shall be fixed in the specified area, with the wave of ups and downs, like a beacon of on both sides of the channel. Don't look at it in the big sea is not obvious, but its role is not small, it can be in any harsh environment for a long time. Continuous. All-weather work, daily schedule and timing measurement of 10 kinds of hydrological and meteorological elements.

The ocean is the place: sometimes change unpredictably weather, as sometimes tempestuous waves, in a thundering rage. In order to understand its temper, people built ocean stations in the coastal and island, measuring height. Ocean current. Sea surface temperature. Tide. Wind velocity. Air pressure and other hydrological elements, the master of these information, will bring more convenience to people. For example, know the storms region, sailing will avoid the walk, eliminating the ship of overlying casualties of the tragedy; know the direction of ocean current, sea and as far as possible along the walk, to save the sailing time and energy consumption; know the abnormal elevation of tide, timely preparedness emergencies, tries to in disasters will loss is reduced to a minimum. Also, the information obtained from the marine Observatory is essential to the study of marine engineering and marine science.

Form

Generally speaking, the whole project is divided into two parts of the ocean and underwater. The water part is equipped with a variety of meteorological elements of the sensor, the measurement of wind speed. Wind direction. Air pressure. Temperature and humidity and other meteorological elements; underwater part has a variety of hydrological elements of the sensor, respectively, measuring wave. Ocean current. Tide. Ocean sensing elements such as sea surface temperature and salinity. Signals generated by the sensor, through the automatic processing of the instrument, the transmitter from time to time, the ground receiving station will receive the signal processing, you get the information you need. Some of the buoy is built on a long distance from the land, the signal will be sent to the satellite, and then transmitted to the ground station signals received by the satellite.

Most of the ocean is powered by batteries. But due to the ocean buoy is far from the land, replace the battery is not convenient, there are many ocean buoys equipped with solar power storage devices, and some also use wave energy storage, greatly reducing the number to change the battery, so as to enable more convenient ocean buoy. Economics.
