Problems solved by technology

[0004] However, due to the communication field of view when the blue light emitting LED emits the blue light beam, that is, the included angle of the blue light beam, the communication field of view is generally less than 30°. Blind zone, if the underwater moving target is not within the range of the blue light beam of the underwater blue light communication device, the blue light receiving array of the underwater moving target will not be able to sense the blue light signal, and underwater wireless communication will not be possible

Abstract

The invention discloses an underwater blue light communication device and system, and an underwater mobile target tracking method, belonging to the technical field of underwater wireless communication. The underwater blue light communication device at least comprises an installation base, a blue light emitting LED, a USBL transducer, a turning table, a driving wheel, a speed reducer, a slide ring, an underwater motor, and a control cabin. The blue light emitting LED is fixed on the turning table, the turning table is fixed with the slide ring, the driving wheel is connected with the turning table through a synchronous belt, the driving wheel is connected with the speed reducer, the underwater motor is connected with the speed reducer, the underwater motor is connected with the control cabin, the speed reducer, the underwater motor and the slide ring are fixed above the installation base, and the USBL transducer and the control cabin are fixed below the installation base. The communication angle of visual field of the blue light beam is increased, and when the underwater mobile target is not within the communication angle of visual field of the blue light beam, underwater blue light communication still succeeds, so that the underwater blue light communication device and the underwater mobile target keep communicating.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of underwater wireless communication, in particular to an underwater blue light communication device and system, and an underwater moving target tracking method. Background technique [0002] Underwater mobile targets include autonomous submersibles, remote-controlled submersibles, and manned submersibles. When underwater mobile targets perform tasks such as underwater motion remote control and seabed monitoring big data recovery, they need to communicate with underwater docking stations and fixed submarines. Underwater communication devices such as observation stations perform underwater wireless communication. [0003] In the prior art, in order to meet the requirements of applications such as real-time motion remote control and large-capacity data transmission of underwater moving targets, underwater blue-ray communication devices are used for underwater communication. The wavelength...
