The main control circuit module 600 is respectively in communication with the optical communication module 300, the power module 400 and the transceiver antenna 700, and the main control circuit module 600 further has a data processing function and can control other modules.
Specifically, the optical communication module 300 and the power module 400 are located below the base 100, when the power buoy works, the lower part of the base 100 is located in the water, the optical communication module 300 is located below the base 100, and the optical communication module can be better in optical communication with the underwater robot, and in combination with the annular buoyancy body 200, the annular buoyancy body 200 does not block the optical communication path of the optical communication module 300, and a sufficient view can be ensured. The power module 400 is located below the base 100 and contacts with the water body, so that power can be better applied to the water body to generate a driving force to drive the buoy to move. In other embodiments, if the power of the power module 400 acts on air, the action module 400 can also be arranged above the base 100 by pushing the air to generate a pushing force.
In the present embodiment, the power module 400 includes a propeller 410. The number of the propellers 410 is four, and the propellers 410 are connected to the buoyant body 200 through the lower support bar 411.

The underwater robot receives the instruction, collects the image or video information, transmits the collected information to the buoy through optical communication, transmits the information to the ARM processor 2 after the photoelectric detector 320 detects the optical signal, demodulates and decodes the signal, and finally transmits the underwater image/video information to the main control circuit module 600. The main control circuit module 600 communicates with the land equipment through the transceiving antenna 700, and transmits the underwater image/video information of the main control circuit module 600 to the land equipment, or transmits a control instruction transmitted by the land equipment to the main control circuit module 600. The transceiving antenna 700 is connected with the base 100 through the upper supporting rod 710, and the transceiving antenna 700 can be lifted by a certain height through the upper supporting rod 710, so that the communication fluency of the transceiving antenna 700 can be improved, and the transceiving antenna 700 is prevented from being corroded by water.
The LD light source array 310 employs a 470nm blue light band light source or a 520nm green light band light source, and the light wave in this band range is used as a communication carrier, which has the advantages of large bandwidth, high speed and strong anti-interference.
