Abstract

The invention discloses a cross-water-surface clock synchronization system, and the system comprises a water surface buoy, an overwater device, an underwater device and a buoy clock source, wherein the overwater device, the underwater device and the buoy clock source are arranged on the water surface buoy. The buoy clock source generates a water surface buoy time reference; the overwater device is positioned above the water surface and is used for synchronizing the buoy clock source and the land clock source; and the underwater device is used for completing time synchronization of the buoy clock source and the underwater carrier. The application also includes a method of implementing synchronization of cross-surface clocks using the system. According to the invention, the problem that the unmanned underwater vehicle cannot receive the common time signal and is difficult to detect the common land reference time is solved.

Description

technical field [0001] The present application relates to the fields of electronics and communication, and in particular to a sleep time synchronization method and system. Background technique [0002] With the continuous development of marine industry fields such as marine resource exploration and deep-sea search and rescue, people's demand for intelligent and unmanned underwater vehicles continues to increase. Intelligent and unmanned underwater vehicles can reduce the difficulty of underwater operations and improve the accuracy and reliability of various underwater operations. The high-precision time reference will be one of the basic prerequisites for the efficient and normal operation of intelligent and unmanned underwater vehicles, and it is an unavoidable technical problem. Since the current time synchronization technology based on electromagnetic wave signals cannot propagate underwater, the most important means for underwater vehicles to provide a time reference du...
