Embodiment 1

[0049] See figure 1 , which shows a schematic diagram of the logical structure of the underwater visible light communication system provided by the present application. The underwater visible light communication system includes: an underwater unmanned robot 11, an underwater backbone network node device 12, and a plurality of different underwater sensors .

[0050] The underwater backbone network node device 12 communicates with each of the underwater sensors through optical fiber communication.

[0051] In this embodiment, since the sensors deployed underwater can collect surrounding information without autonomous movement, optical fibers are used to connect the underwater sensors to the underwater backbone network node device 12, so that the underwater backbone network node device 12 is connected to the Each of the underwater sensors is communicatively connected through optical fiber communication. Optical fiber transmission is less affected by the underwater environment, ...

Embodiment 2

[0078] This embodiment provides an underwater visible light communication method, based on the underwater visible light communication system shown in Embodiment 1, please refer to Figure 5 , which shows a flow chart of the underwater visible light communication method provided by the present application, which may include the following steps:

[0079] Step S51: The underwater backbone network node device receives the task allocation instruction sent by the underwater unmanned robot, and forwards the task allocation instruction to the corresponding underwater sensor.

[0080] Step S52: The underwater backbone network node device obtains the information collected by each of the underwater sensors.

[0081] In this embodiment, the underwater backbone network node device acquiring the information collected by each of the underwater sensors may specifically be that the underwater backbone network node device regularly acquires the information collected by each of the underwater se...

Abstract

The application provides an underwater visible light communication system and method. The underwater visible light communication system comprises an underwater unmanned robot, an underwater backbone network node device and multiple different underwater sensors, wherein the underwater backbone network node device is respectively in communication with each underwater sensor through optical fiber communication; the underwater unmanned robot is in communication with the underwater backbone network node device through visible light wireless communication. According to the underwater visible light communication system and method, influence of the visible light wireless communication due to underwater environment is small, and underwater transmission rate of the visible light wireless communication is relatively higher, so that information acquisition efficiency of the underwater unmanned robot is improved, and the timeliness of feeding back underwater information to a shore-side base station by the underwater unmanned robot is also improved.

Description
