Underwater portable wireless optical communication equipment and system

Abstract

The invention discloses a underwater portable wireless optical communication equipment and system, relates to the field of underwater wireless optical communication, and aims to solve the problems that an underwater wireless optical communication channel is extremely unstable and underwater information is difficult to continuously and efficiently transmit due to the fact that existing underwater wireless optical communication equipment cannot be stably aligned with overwater wireless optical communication equipment. According to the scheme, the equipment comprises a wearable device and a suspension device, the suspension device is connected with the wearable device in a wired or wireless mode, blue, green and red light emitted by the suspension device is received by a receiving device of overwater communication equipment, and wireless optical communication between the underwater wireless optical communication equipment and the overwater communication equipment is achieved. The suspension device is not affected by irregular motion of a frogman, and optical communication alignment and stability between the suspension device and the overwater communication equipment are better guaranteed. the wireless optical communication system can control the transmitting module to adjust the angle and the direction in real time, so that the transmitting module is aligned with the receiving device of the overwater optical communication equipment at any time, the stability of an optical communication channel is ensured, and the transmission efficiency of optical communication is improved.

Description

technical field [0001] The invention relates to the field of underwater wireless optical communication, in particular to an underwater portable wireless optical communication device and a communication system. Background technique [0002] As a new type of communication technology, optical wireless communication has the advantages of both optical fiber communication and mobile communication. It can realize broadband transmission, flexible networking, no frequency application, and anti-electromagnetic interference. research has received extensive attention. [0003] As land resources are gradually fully explored, the problem of shortage of various resources on land has gradually emerged, while most of the ocean, which accounts for nearly 70% of the earth, has not been explored and exploited. The ocean contains a large amount of resources. At present, underwater communication is basically Relying on optical fiber transmission, but the optical fiber needs to be pre-laid with c...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art that the underwater wireless optical communication equipment attached to the frogman moves irregularly, irregularly, and uncertainly with the frogman underwater, causing the underwater wireless optical communication equipment to fail. Stable alignment with the wireless optical communication equipment on the water leads to the extreme instability of the optical communication channel, and it is difficult to continuously and efficiently transmit underwater information. A kind of underwater portable wireless optical communication equipment and communication system is proposed
