Underwater portable wireless optical communication system and method

Abstract

The present invention relates to an underwater portable wireless optical communication system and method. The system comprises a main optical communication system and a slave optical communication system. The main optical communication system is configured to actively require communication and drop out of the establishing of a communication link; the slave optical communication system is still ina passive receiving state, and when the alignment light emitted by the main optical communication system is received, the establishing of the communication link is rapidly completed and the communication is performed. The underwater portable wireless optical communication system and method can achieve underwater communication with a long distance, a high rate and high invisibility. The underwaterportable wireless optical communication system and method solve the active communication problem, achieve passive receiving, and are high in flexibility and good in communication stability. The systemis simple, portable and easy to carry, and can be implemented. The main optical communication system can be fixed at a carrier's front chest, left and right shoulders or frogman mask, and the slave optical communication system can be fixed on an oxygen bottle without influence of the normal activity of the carrier underwater.

Description

technical field [0001] The invention belongs to the field of underwater communication, and in particular relates to an underwater portable wireless optical communication system and a communication method. Background technique [0002] Oceans and lakes occupy more than two-thirds of the earth's area, and it is an important field of human exploration activities. Underwater communication provides great convenience for human beings to explore ocean and lake resources, observe lake and sea organisms, abnormal volcanic vibrations on the sea floor, search and rescue at sea, salvage shipwrecks, explore underwater relics, and underwater military confrontation. [0003] The electromagnetic wave communication commonly used on land is severely attenuated in water, and the communication distance is severely restricted. Even if the ultra-low frequency band can achieve long-distance communication, the low communication rate and complicated communication equipment are its shortcomings that ...

Problems solved by technology

[0003] The electromagnetic wave communication commonly used on land is severely attenuated in water, and the communication distance is severely restricted. Even if the ultra-low frequency band can achieve long-distance communication, the low communication rate and complicated communication equipment are its shortcomings that cannot be erased.
