Underwater blue-green light high-speed full-duplex communication-in-motion system and method

Abstract

The invention provides an underwater blue-green light high-speed full-duplex communication-in-motion system and method, and solves the problems of large time delay, low communication rate, poor carrier maneuverability and adoption of a half-duplex communication mode in existing underwater wireless communication. The system comprises two communication devices which communicate with each other; each communication device comprises a transmitter and a receiver; the transmitter comprises a master control and information interaction unit, a modulation and driving unit, an optical signal transmitting array and a homogenizing mirror; the main control and information interaction unit processes the service data and outputs a square wave signal; the modulation and driving unit outputs N paths of excitation signals according to the square wave signal; the optical signal emission array comprises N laser diodes connected in parallel; the receiver comprises a wavelength selection unit, a bias voltage unit, a diversity reception and gating unit, a variable gain amplifier unit and an ADC circuit unit. Wherein the transmitter of one communication device outputs signal blue light, the transmitter of the other communication device outputs signal green light, and the receivers of the two communication devices receive signals output by each other.

Description

Technical field [0001] The present invention belongs to the field of optical communication, relates to underwater wireless communication technology, specifically relates to an underwater blue-green light high-speed full-duplex system and method. Background [0002] In recent years, human beings have paid more and more attention to the exploration of the ocean, and underwater detection equipment technology is also becoming the focus of marine science and technology competition. With the rapid development of marine equipment, on the one hand, large-scale, super-resolution massive marine observation data need to be transmitted back in quasi-real time to be effectively used; on the other hand, underwater submersibles / vehicles / landers / frogs need to communicate with each other and control long distances, which put forward the requirements of low latency, high speed, full duplex and dynamic communication equipment for underwater communication equipment. [0003] The existing underwater...
