Ship-borne automatic weather station observation system is a kind of weather observation system with the ship as the working platform, it can accomplish the real-time observation for ocean meteorological factors such as temperature, barometric pressure, humidity, wind speed, wind direction, rainfall, visibility, etc., in addition, it can be equipped with observations of ocean hydrological factors such as sea temperature and sea salt on demand.
Characteristics and Applications
In order to get accurate wind direction and speed data, the wind measurement data of ship-borne automatic weather station need to be corrected by ship speed and course data. In order to improve the measurement accuracy of the speed and course data of ships, differential beidou and GPS positioning systems are put into use, so that accurate speed and course data can be obtained in sync with the wind measurements through effective real wind correction processing. At the same time, in order to accurately grasp the ship left and right chord wind difference, the system designed a special left and right chord which can be connected to two sets of wind measurement system.
The power supply of ship-borne automatic weather station is usually supplied by alternating current and solar energy, which can ensure the stable operation of ship-borne automatic weather station.
The data communication of the automatic weather station on board ships is mainly based on the Beidou Communication Mode. At the same time, it supports GPRS wireless data communication mode, small short-wave radio and other communication modes.
The installation of the automatic weather station is made of 316 stainless steel to ensure the corrosion resistance of the structural components.
