Abstract

The invention provides a wireless and underwater sound communication buoy, which is of a cordwood-type structure and comprises a VHF (Very High Frequency) antenna, a GPS (Global Positioning System) antenna, an antenna watertight base, a navigation light, a wireless support rod upper section, a hard polyurethane foam body, an antenna support rod lower section, a watertight electronic instrument cabin, a water-resistance load-bearing cable, a receiving/transmitting combined transducer and lead fish in sequence from top to bottom. The wireless and underwater sound communication buoy is characterized by further comprising a wireless communication module, an underwater sound communication module, a comprehensive controlling/processing module and a battery/power supply management and control module; the wireless communication module is used for realizing functions of a wireless communication data link layer and a physical layer; the water sound communication module is used for realizing the functions of an underwater sound communication data link layer and the physical layer; the comprehensive controlling/processing module is used for realizing the functions of a wireless and underwater sound communication network layer and an application layer and simultaneously realizes whole control on the buoy; and the battery/power supply management and control module is used for controlling, maintaining and managing a power supply.

Description

Technical field [0001] The present invention relates to the technical field of underwater acoustic communication and wireless network communication, in particular to a wireless and underwater acoustic communication buoy. Background technique [0002] Since the 1990s, increasingly mature underwater acoustic communication technology has promoted the development of underwater sensor networks. Due to the important value of underwater sensor networks in the fields of marine environmental monitoring, marine resource exploration, military reconnaissance, anti-terrorism and anti-submarine, all countries have invested heavily in research and development of related technologies. [0003] The development of underwater sensor networks urgently requires the establishment of surface communication control nodes (such as shipborne, airborne, or shore-based control command stations) and underwater information nodes such as sensor arrays, underwater unmanned automatic vehicles, water downloaders, et...
