Distributed scattering optical fiber underwater communication control system

Abstract

The invention provides a distributed scattering optical fiber underwater communication control system. The system comprises: an overwater emitting part used for emitting a first optical signal with a first wavelength; a transmission optical fiber, wherein one end of the transmission optical fiber is connected with the overwater emitting part, and a plurality of light scattering points are arranged at preset position points of the transmission optical fiber; underwater transceiving parts which are arranged at underwater preset positions and correspond to underwater light scattering points of the transmission optical fiber respectively, so that the underwater transceiving parts and the light scattering points form a light transmission channel, and the underwater transceiving parts receive the first light signals transmitted by the overwater transmitting part; and an overwater receiving part which is arranged corresponding to a light scattering point of the transmission optical fiber arranged on the water surface, and forms a light transmission channel with the light scattering point so as to receive the light signals transmitted by the plurality of underwater transceiving parts. According to the communication control system combining underwater optical fiber communication and underwater wireless optical communication, the problem of the communication distance of underwater optical signals is solved, the communication distance of the underwater optical signals is greatly increased, and underwater networking and layout are more convenient.

Description

technical field [0001] The present disclosure relates to the technical field of underwater optical communication, in particular to a distributed scattering optical fiber underwater communication control system. Background technique [0002] The ocean, as the area with the largest surface area, accounts for as much as 71% and contains abundant resources. However, with the increasing exploitation and consumption of land resources, the ocean has gradually attracted widespread attention. In this form, the needs of underwater fishing, detection and security also tend to be extensive. Therefore, the field of underwater communication has gradually become one of the research hotspots. [0003] At present, the common communication methods in the field of underwater communication include underwater acoustic communication, underwater wireless radio frequency communication and underwater optical communication. Among them, underwater optical communication mainly includes two categorie...

AI Technical Summary

Problems solved by technology

However, although underwater wireless optical communication is relatively easy in terms of networking and layout, its communication distance is greatly limited due to factors such as seawater loss and turbulence during information transmission.

At the same time, although underwater optical fiber communication has greatly improved in communication distance, it is very difficult in underwater networking and layout.
