Cable-free communication autonomous underwater vehicle

Abstract

The invention relates to the field of unmanned autonomous vehicle communication system design, in particular to a cable-free communication autonomous underwater vehicle. Various wireless communicationdevices such as low power consumption, high speed and underwater acoustic communication are integrated on the autonomous underwater vehicle, and all the wireless communication devices are used underdifferent task stages; a low-power-consumption module is used in the awakened stage of the autonomous underwater vehicle, used for a small amount of data communication between the autonomous underwater vehicle and a carrier when the autonomous underwater vehicle does not leave from the carrier and used for receiving carrier instructions; a high-speed wireless module is used for meeting the high-speed data communication needs before the autonomous underwater vehicle is launched or when the autonomous underwater vehicle is exposed out of the water surface; and underwater acoustic communication is used for meeting the need of a small amount of data communication of the autonomous underwater vehicle during underwater working. The various wireless devices of different types constitute an autonomous underwater vehicle cable-free communication technology jointly. Cable-free communication between the autonomous underwater vehicle and the carrier is achieved, manual intervention in the whole process is not needed, when entering water to work and obtaining a large number of task data which need to be transmitted back, the autonomous underwater vehicle only needs to float upwards, recovery isnot needed, cable butt joint is not needed, and the working efficiency of the autonomous underwater vehicle is effectively improved.

Description

technical field [0001] The invention relates to the design field of an unmanned autonomous underwater vehicle communication system, in particular to a cableless communication underwater vehicle. Background technique [0002] In recent years, drones, unmanned vehicles, unmanned boats and unmanned submarines have played an increasingly widespread role in the military and civilian fields. Compared with the rapid development of other unmanned platform technologies and applications, unmanned boats and unmanned underwater vehicles started relatively late, but developed rapidly, and have now been highly valued by the world's maritime powers. Unmanned boats are used to perform water tasks, and are characterized by long range and heavy load. Unmanned underwater vehicles are used to perform underwater missions and have relatively short ranges. Unmanned submersibles are generally carried on other carriers to perform high-sea missions. When the carrier is an unmanned ship, there is no...

AI Technical Summary

Problems solved by technology

Unmanned submersibles are generally carried on other carriers to perform high-sea missions. When the carrier is an unmanned ship, there is no human intervention in the whole process of launching, executing tasks, and recovering the submersible, while wired communication requires the use of technologies such as automatic separation and docking. It is too complicated to meet this demand, so it is necessary to establish a whole-process wireless communication system to realize the full-process autonomous work of the unmanned submersible; currently there is no relevant wireless communication system design content
