Underwater wireless optical communication and imaging detection integrated device

Abstract

The invention discloses an underwater wireless optical communication and imaging detection integrated device. The device comprises an imaging detection module and a power supply module which are installed in a watertight shell, and is characterized in that the device further comprises an optical communication module and an optical transceiving antenna which are installed in the watertight shell, the imaging detection module collects and processes a target image and transmits the target image to the optical communication module through a communication interface, the optical communication modulecomprises a sending module and a receiving module, the device adopts a duplex communication mode, and at the sending end, the sending module processes a video image acquired by the imaging detectionmodule into signal light and sends the signal light to a seawater channel through the optical transceiving antenna, and the signal light reaches the optical transceiving antenna of the receiving end after signal transmission at a certain distance and is output to a display terminal after being processed by the receiving module. Active illumination of the blue light LED wireless optical communication module and active illumination of the imaging detection module are integrally designed, an LED and an optical emission lens are shared, and therefore the device has the advantages of being small insize, low in power consumption and high in efficiency.

Description

technical field [0001] The invention relates to an underwater wireless optical communication and imaging detection integrated device (hereinafter referred to as the device), which solves the problems of signaling, image data collection and transmission in the process of underwater operations, especially deep sea operations, and provides technology for real-time monitoring of underwater operations Assure. Background technique [0002] In recent years, strategic competition in the maritime domain has intensified and has become an important global security concern. Therefore, how to carry out underwater operations efficiently, conveniently and reliably has become a research hotspot in various countries. Due to the complex underwater environment, especially in the deep sea, where there is no light all year round, and the maneuvering of platforms or operating objects needs to be considered, the "cable" communication method brings a lot of inconvenience and potential safety hazar...

Problems solved by technology

In addition, the Xiguang Institute of the Chinese Academy of Sciences, Zhejiang University, Ocean University of China and Nanjing University of Posts and Telecommunications have also carried out related technical research, but the communication distance is relatively short when the communication rate is greater than 1Mbps, and the integrated device that takes into account the imaging detection function is still rarely reported.
