An Air-Underwater Communication System Based on Air Platform

Abstract

The invention discloses an air-underwater communication system based on an aerial platform. The air-underwater communication system comprises the aerial platform carrying a blue-green light communication unit, wherein a control unit on the aerial platform control an aircraft to fly to an area where an underwater collector or detector is approximately located; and a scanning and positioning unit is used to scan and position the area where the underwater collector or detector is approximately located, and a launch angle of a light source is controlled, so that an effective communication coverage area in a certain area is realized. The blue-green light communication unit transmits a data demand command signal to the underwater collector or detector, after the collector or detector receives a command request, the collector or detector sends a feedback signal to the aerial platform, so that a communication link between the aerial platform and the underwater collector or detector is established. In comparison with other fixed and wired optical communication ways, the air-underwater communication system based on the aerial platform has the advantages of good security, quick data acquisition, low cost, high sensitivity, wide application range and the like.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an air-underwater communication system based on an air platform. Background technique [0002] At present, my country has initially formed the basic framework of an ocean observation network covering shore-based ocean observation systems, offshore ocean observation systems, and ocean and polar observations, which have played an important role in my country's marine disaster prevention and mitigation, scientific research, national defense and security. Deploying underwater detection equipment such as hydrophones in some sensitive waters is an important underwater security measure. One of the important technical difficulties is how to efficiently collect the data collected by these underwater detection equipment. [0003] In the process of realizing the data return of the underwater detection network, the existing technology not only consumes a lot of manpower, mater...
