Buoy chain loaded inclination ocean current measuring system and ocean current and wave measuring method

Abstract

The invention belongs to the technical field of ocean current observation, and relates to an ocean current and wave measuring device and method. The buoy chain loaded inclination ocean current measuring system comprises a surface buoy body, an ocean current meter and a mooring rope; one end of the mooring rope is connected with the bottom of the surface buoy body, and the other end of the mooringrope is anchored on the seabed; the ocean current meter is dragged and connected to the mooring rope; and the ocean current meter comprises a collecting / processing module used for acquiring the inclination angle, the direction and the depth of the ocean current meter and converting into a flow velocity value, a flow direction value, a depth value of the ocean current and the wave data and storingthe data. The buoy chain loaded inclination ocean current measuring system can be used for installing a plurality of inclined ocean current meters at different depths, so that the ocean current in different depths can be continuously observed for a long time; and surface wave measurement can be carried out by utilizing an ocean current value close to the position of the water surface.

Description

technical field [0001] The invention belongs to the technical field of ocean current observation, and relates to a measuring device and method for ocean currents and waves. Background technique [0002] The ocean area accounts for about 71% of the earth's area, and the ocean current is one of the dynamic elements of the ocean and an important oceanographic parameter. Observation of ocean currents is an important part of marine surveys. Mastering the laws of seawater flow can not only serve national defense, marine transportation, fishery, and port construction, but also has close ties with research in other fields of marine science, such as the formation of water masses, the interior of seawater and The heat exchange between the sea-air interface is related to the study of ocean currents. Marine currents are considered important parameters in marine environmental protection, marine environmental assessment, marine engineering development, marine climate, marine disaster pre...

AI Technical Summary

Problems solved by technology

At present, there are few relevant domestic researches, and the inclined current meters developed abroad are only suitable for long-term observation of seabed current velocity and direction, and are easily disturbed by seaweed and plankton. Professional divers are required to install them, and the measurement sensors are single, The data processing method is simple and cannot adapt to the ocean current measurement under the environment of sea surface wind and waves
