Autonomous underwater vehicle based on optical fiber communication buoy

Abstract

The invention discloses an autonomous underwater vehicle based on an optical fiber communication buoy, belonging to the technical field of communication buoys. Through the real-time communication between the optical fiber communication buoy equipped with high-speed wireless transmission equipment and the control system or the operating mother ship, real-time and large-capacity transmission of the detected information can be realized, and it can get rid of the constraints of optical fibers or cables. The autonomous underwater vehicle includes a vehicle body and an optical fiber communication buoy; the optical fiber communication buoy is detachably installed on the aircraft body, and the optical fiber communication buoy is connected to the underwater vehicle body through an optical fiber for signal transmission; The communication buoy is equipped with high-speed wireless communication equipment consisting of an antenna and a circuit board of a high-speed wireless transmission station; when the autonomous vehicle arrives at the set water area and needs to communicate, the optical fiber communication buoy is separated from the aircraft body, and the optical fiber communication buoy floats to the water surface. High-speed wireless communication equipment realizes real-time communication between the aircraft body and the shore-based control system / operating mother ship.

Problems solved by technology

However, for aircraft with limited size and weight, the installed underwater acoustic communication has small size, narrow transmission bandwidth, low transmission rate, and is greatly affected by the underwater acoustic environment underwater, making it impossible to transmit large-capacity information in real time , can only monitor the underwater state of the aircraft and transmit information in some specific cases, such as emergency treatment through underwater acoustic communication

Autonomous unmanned underwater vehicles can only use dedicated communication interfaces or wireless data downloads after recovery for post-analysis and processing, which is inefficient for tasks that require timely processing and manual confirmation of target information

If optical fibers or cables are added to the aircraft, it is necessary to equip an operating mothership to follow the aircraft to carry out underwater operations. For places with complex or shallow waters, the difficulty and cost of the operation will be greatly increased, which will affect the efficiency of the operation, and the increased optical fiber or cable length valid
