AI Technical Summary
When underwater autonomous unmanned vehicles encounter accidents in complex marine environments, they are prone to losing contact. The communication modules of existing electrical control methods are easily interfered with, making positioning difficult.
A passive vacuum adsorption emergency positioning system was designed, which utilizes a micro-opening safety valve with one active and one standby valve to automatically open at a set depth, causing the communication component to float to the water surface and transmit positioning signals through the Beidou unit.
When an unmanned vehicle loses contact, it can automatically locate and transmit position information, avoiding reliance on electrical system control and improving search efficiency in complex marine environments.
