The invention discloses a sea-air coupling real-time observation buoy system based on Beidou Iridium double-star communication, comprising a sea-air coupling observation sensor unit, a data acquisition communication control unit, an anchor unit, a buoy body platform, a power supply unit and data processing The center; buoy data acquisition and communication unit adopts the Beidou satellite system for transmission, which has higher requirements for data security and lower requirements for communication volume. Conventional block method air-sea flux, upper ocean current profile and buoy operating state parameters. The Iridium system is used to transmit high-frequency eddy correlation and high-resolution sea surface temperature profile data that require high communication traffic. The buoy can realize the simultaneous real-time observation of the turbulent flux parameters of the mobile platform eddy correlation method, the flux parameters of the block method, the 0-1.0m high-resolution skin surface temperature profile of seawater, and the 0-70m upper ocean current profile.

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.
