All-weather ocean mooring buoy early-warning system and method based on sound detection

Abstract

The invention relates to an all-weather ocean mooring buoy early-warning system and method based on sound detection. The system includes: microphones installed around an ocean mooring buoy and used for performing audio detection on suspicious ships in various directions on the sea surface; analysis and comparison modules for analyzing audios to determine the orientation and the proximity degree of a suspicious ship; range finding modules for measuring the distance between the suspicious ship and the ocean mooring buoy in real time according to the result of the analysis and comparison module; early warning and voice communication modules for sending alarm information to a shore workstation via satellite communication if the result of the range finding module is less than the set distance; a central processing module for selecting the range finding module or early warning and voice communication module at the corresponding direction according to the result of the analysis and comparison module and achieving communication between a worker at the shore workstation and a suspicious person through the satellite communication; a power control module for switching on the range finding module or the early warning and voice communication module at the direction where the suspicious ship appears.

Description

technical field [0001] The invention belongs to the field of ocean monitoring, in particular to an all-weather ocean mooring buoy early warning system and method based on sound detection. Background technique [0002] The oceanic moored buoy is a surface moored marine hydrometeorological automatic observation platform deployed in the ocean far away from the mainland, and provides real-time marine hydrometeorological data for marine scientific research and related fields through satellites. Because it is far away from the mainland, it will be unattended after deployment and will work for one year. When fishermen in the nearby waters pass by the working buoy, they often have a strong curiosity about the buoy, or directly use it as a fishing platform, which leads to people getting too close to the buoy or even boarding the buoy, causing damage to the buoy. In addition, cases of buoy theft also occur from time to time. These external interventions have seriously affected norma...

When fishermen in the nearby sea pass by the working buoy, they often have a strong curiosity about the buoy, or directly use it as a fishing platform, which leads to people getting too close to the buoy or even boarding the buoy, causing damage to the buoy

In addition, cases of buoy theft also occur from time to time

These external interventions have seriously affected normal ocean monitoring work

[0003] At present, the monitoring method using images has the disadvantages of large power consumption and incapable of all-weather monitoring. Due to the limited power supply at sea, it is necessary to study a method that can reduce power consumption and is suitable for all-weather monitoring and early warning.
