Example Embodiment
[0048] Example one
[0049] See figure 1 , Which shows a schematic diagram of a 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 number 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 underwater sensors do not need to move autonomously to collect surrounding information, the underwater sensors are connected to the underwater backbone network node device 12 using optical fibers, so that the underwater backbone network node devices 12 are connected to each other separately. Each of the underwater sensors communicates through optical fiber communication. Optical fiber transmission is less affected by the underwater envi...
Example Embodiment
[0077] Example two
[0078] This embodiment provides an underwater visible light communication method. Based on the underwater visible light communication system shown in the first embodiment, please refer to Figure 5 , Which shows a flow chart of the underwater visible light communication method provided by this 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 acquires the information collected by each of the underwater sensors.
[0081] In this embodiment, the acquisition of the information collected by each underwater sensor by the underwater backbone network node device may specifically be that the underwater backbone network node device regularly acquires the information collected by each un...
