Abstract

The invention discloses a sea-gas coupled real-time observation buoy system based on Beidou satellite and Iridium satellite double-satellite communication. The sea-gas coupled real-time observation buoy system comprises a sea-gas coupled observation sensor unit, a data collecting communication control unit, an anchoring unit, a buoy body platform, a power supplying unit and a data processing center. The buoy data collecting communication control unit adopts a Beidou satellite system to transmit conventional block method sea-gas flux, upper-layer sea current profile and buoy operation state parameters which have high requirements on data safety and low requirements on the communication quantity, and adopts an Iridium satellite system to transmit high frequency eddy related and high-resolution seawater skin surface temperature profile data which have high requirements on the communication quantity. A buoy can synchronously observe turbulence flux parameters of an eddy-related method of amovable platform, flux parameter of a block method, the seawater 0-1.0 m high-resolution skin surface temperature profile and the 0-70 m upper-layer sea current profile in real time in real time. Thesea-gas coupled real-time observation buoy system is suitable for being released in deep and open sea, and has the characteristics of diverse sea-gas interface observation parameter, safe data transmission and the like.

Description

technical field [0001] The invention relates to the technical field of deep-sea ocean detection, in particular to a sea-air coupling real-time observation buoy system based on Beidou Iridium double-star communication. Background technique [0002] The eddy correlation method measures and calculates the fluctuating values ​​of physical quantities (such as temperature, CO 2 、H 2 O, etc.) and the vertical wind speed to calculate the turbulent flux, which has almost no assumptions in the process of observing and calculating the flux, and is considered to be the only standard method that can directly measure the flux of energy and matter exchange between the biosphere and the atmosphere . However, due to the complexity of the offshore environment and the limitations of some specific conditions, including the movement of the mobile platform itself and the influence of the platform on the airflow, the measurement accuracy is affected, so the flux observation of the mobile platfor...

AI Technical Summary

Problems solved by technology

Although my country has launched a large number of satellites with thermal infrared sensors (meteorological series satellites, ocean series satellites, environmental satellites, high-resolution satellites, etc.), and can receive foreign satellite data for free, there are no high-precision SST products. Infrared sensor calibration is very difficult, especially the lack of offshore field observation calibration data

The difficulties in offshore calibration are mainly due to the low accuracy of on-site temperature measurement, insufficient spatial resolution of surface temperature, and difficulties in fixed-point observation at sea.
