Real-time three-dimensional observation system for marine fishery aquaculture water area

Abstract

A real-time three-dimensional observation system for a marine fishery aquaculture water area comprises a plurality of seabed sensor nodes, a plurality of sea surface buoy nodes and an onshore monitoring system, and the seabed sensor nodes comprise hydrology and water quality sensors and are used for collecting seabed hydrology and water quality data; the sea surface buoy nodes comprise hydrological, water quality and meteorological sensors and are used for collecting sea surface hydrological, water quality and meteorological data, the sea surface buoy nodes exchange data with the seabed sensornodes through underwater acoustic communication, and meanwhile the positions of the seabed sensor nodes are measured according to underwater acoustic positioning. And the land monitoring system receives the data sent by the sea surface buoy nodes through satellite communication, obtains hydrological, water quality and / or meteorological data about the seabed and the sea surface, and obtains position data of the seabed sensor nodes.

Description

technical field [0001] The invention belongs to marine fishery cultivation technology, in particular to a real-time stereoscopic observation system for marine fishery cultivation waters. Background technique [0002] my country is a big country in marine fish farming. In 2018, the output of marine fish farming accounted for 70% of the output of marine fish. However, fish farming relies heavily on the environment of the aquaculture waters. Changes in the environment of the aquaculture waters, such as meteorology, hydrology, and water quality, directly affect the growth and even survival of farmed fish. Pollution, red tide (green tide) disasters and other extreme events, such as Penglai 19-3 oil spill accident and Dalian oil pollution incident, directly affect the environment of aquaculture waters and threaten the safety of marine aquaculture fish. Therefore, the monitoring of the aquaculture water environment plays a very important role in marine fish farming. The marine aq...
