Marine monitoring buoy device and system based on water surface and underwater target early warning

Abstract

The invention discloses a marine monitoring buoy device and system based on water surface and underwater target early warning. The device comprises a buoyancy compartment, a water surface target recognition and early warning device, a positioning and signal transmission device used for communication, an underwater heavy block located on the lower portion of the buoyancy compartment, a plurality ofstandard hydrophones, an underwater laser radar and a bottom anchor. When the monitoring buoys are arranged on the sea, target recognition and early warning systems are arranged on the water surfaceand under the water, and the possibility that the buoys are damaged is fundamentally eradicated. By establishing a single-photon laser radar fine imaging model, through sequential denoising of depth,intensity and image background and point cloud recovery, fine image features can be presented, effective early warning can be performed, and the requirements of speed and definition can be met; the data acquisition system adopts an ADC component based on a low-power-consumption embedded industrial personal computer, a high-capacity solid state disk and 12-channel synchronous sampling, is suitablefor signal acquisition with phase relationship requirements among different channels, and meets the complex wiring requirements of different sensors.

Description

technical field [0001] The invention relates to the technical field of marine buoys, in particular to a marine monitoring buoy device and system based on early warning of water surface and underwater targets. Background technique [0002] In recent years, with the country's emphasis on marine basic technology and continuous investment in development, ocean buoy technology has made great progress. Relying on ocean buoys to obtain ocean and meteorological data information in specific sea areas is a topic worthy of research. In the existing technology, the monitoring buoys are basically in an unattended state after they are launched. The special working mode leads to serious man-made (theft) damage to the remote sea monitoring buoys placed in this type of sea area. The internal hydrometeorological sensors and The core valuable components were stolen, resulting in the interruption of the work of the monitoring buoy, making it impossible to continuously measure and collect, and e...

In the existing technology, the monitoring buoys are basically in an unattended state after they are launched. The special working mode leads to serious man-made (theft) damage to the remote sea monitoring buoys placed in this type of sea area. The internal hydrometeorological sensors and The core valuable components were stolen, resulting in the interruption of the work of the monitoring buoy, making it impossible to continuously measure and collect, and eventually completely losing all the information of the ocean monitoring buoy

Because this type of buoy is limited to the collection and measurement of hydrological parameters and meteorological data, it lacks identification and early warning of water surface and underwater targets, and is often destroyed by man-made
