Description

technical field [0001] The invention relates to the field of underwater acoustic communication, in particular to a wireless real-time communication system and method for submerged buoys, which are applied to the real-time return of submerged buoy data in ocean observation. Background technique [0002] Ocean observation submersible buoys are mainly used to obtain long-period marine scientific data in deep sea areas, including information such as underwater temperature, salinity, depth, current velocity and direction. Ocean observation submersible buoys are usually deployed at depths of hundreds of meters, thousands of meters or even tens of thousands of meters underwater to observe marine scientific data at different depths. Due to the severe attenuation of conventional electromagnetic waves and optical communications underwater, it is impossible to achieve long-distance underwater information transmission. Therefore, the observation data of submarine targets cannot be trans...

Problems solved by technology

[0004] The purpose of the present invention is to propose a wireless real-time communication system for submerged marks, which utilizes underwater acoustic communication to solve the shortcomings of the existing underwater long-distance communication cables, such as high cost, difficult deployment, and poor reliability. The technology realizes the wireless communication between the underwater buoy and the surface buoy. First, the observation data of the submersible buoy is transmitted to the surface buoy through underwater acoustic communication, and then the buoy transmits the data back to the ground laboratory through the satellite communication module.
