Problems solved by technology

Affected by many aspects, the effective distance of existing underwater visible light transmission is relatively short, and it is still difficult to solve long-distance data transmission, and there are also certain requirements for the transparency of water bodies
Therefore, the adaptability of the existing underwater visible light communication is not enough and needs to be solved urgently

Embodiment 1

[0049] see figure 1 , this embodiment provides an underwater visible light communication device, including: a housing 100, the housing 100 is constructed from two detachable sub-bodies 120, and a group of visible light water The lower transceiver module 200. The ends of the two daughter bodies 120 in this embodiment are bullet-shaped, and the chamber walls at the ends are made of light-transmitting material.

[0050] The bullet-shaped structure is conducive to underwater operations. Just put the sub-body 120 or the housing 100 into the water, and the underwater propulsion device 103 can be operated through the travel controller, so that the underwater visible light communication device can go to any destination. .

[0051] The outer wall of each sub-body 120 is provided with four sets of drainage channels 102 connected to the tail end of the housing 100. In this embodiment, the sub-body can be constructed to work, so the two groups of drainage channels 102 on the opposite si...

Abstract

The present invention is applicable to the technical field of visible light communication, and provides an underwater visible light communication device, comprising: a casing (100), and the casing (100) is constructed by at least two separable sub-bodies (120) The contact surfaces of two adjacent sub-bodies (120) are provided with construction parts for construction, and the non-contact surfaces of the sub-bodies (120) are provided with at least one set of visible light underwater transceiver modules (200). The embodiment of the present invention makes the underwater activities of the device more flexible through the detachable design, and the sub-body can work independently to realize visible light underwater communication; when multiple sub-bodies are assembled, the overall device has multiple groups of visible light underwater transceivers The module can adapt to more communication scenarios at this time. When multiple devices form an optical path, it can also achieve the effect of a visible light communication link and extend the communication distance infinitely.

Description

technical field [0001] The invention belongs to the field of visible light communication, and in particular relates to an underwater visible light communication device. Background technique [0002] Visible light communication is a new type of information technology that uses the high-speed on-off response characteristics of LEDs to realize wireless transmission. Visible light communication has the technical advantages of high speed, no electromagnetic radiation, high density, low cost, rich spectrum and high confidentiality. Especially in December 2015, after being tested and certified by the Ministry of Industry and Information Technology of China, China's "Key Technology Research of Visible Light Communication System" made another major breakthrough, and the real-time communication rate has been increased to 50Gbps, which once again demonstrated the high-speed advantage of visible light in the communication field. [0003] Since radio waves cannot propagate underwater, mo...
