Seafloor observation network-based subsurface buoy device with real-time power supplying and high-speed data transmitting

A seafloor observation network-based subsurface buoy device with real-time power supplying and high-speed data transmitting, wherein the subsurface buoy device comprises a seabed base deployed on a seabed and a vertical mooring system connected to a bottom surface of the seabed base to extend to a sea surface, wherein

• the seabed base is used for providing a function of a gravity anchor, to enable the subsurface buoy device to be stably positioned at a layout site, and is further used for obtaining electrical energy from a junction box of a seafloor observation network, sending, to the vertical mooring system, a management and control command sent by the junction box of the seafloor observation network, and transmitting data collected by the vertical mooring system to the junction box of the seafloor observation network in real time;
• and
• the vertical mooring system adopts a structure that an overall force bearing rope is combined with a segmented main cable, and is used for transmitting the electrical energy obtained from the seabed base to each sensor arranged on the force bearing rope, and sending, to the seabed base, data of the sensors at different water depths according to the management and control command transmitted by the seabed base;
• wherein a positioning beacon and a main floating body are sequentially disposed from a top end to bottom in the vertical mooring system, wherein the main floating body is used for stretching the vertical mooring system through buoyancy;
• wherein a second gathering cabin and an underwater acoustic communication machine are disposed in the main floating body, the second gathering cabin is used for monitoring a periodic instruction sent by a first gathering cabin, and when the periodic instruction can be received, the second gathering cabin is in a slave state;
• and when the periodic instruction cannot be received, the second gathering cabin is in a master state, the data of the sensors collected by the vertical mooring system at different water depths is obtained through a data bus of the main cable, the data is converted into a format required for the underwater acoustic communication machine, and the data in the format is sent by the underwater acoustic communication machine to the junction box of the seafloor observation network.
