Autonomous patrol type aquaculture acoustic monitoring system

Abstract

The invention discloses an autonomous patrol type aquaculture acoustic monitoring system comprising an aquaculture facility, a water surface positioning detection platform and a water surface platform. The water surface positioning detection platform and the water surface platform are connected through a wireless communication protocol. The water surface positioning detection platform comprises awater autonomous patrol platform and a positioning array. The water autonomous patrol platform includes a fishing probe sensor module, a fishing probe signal processing module, a positioning module, amain control module, a communication module and a battery pack which provides working voltage to the main control module, the positioning module, the communication module and the fishing probe signalprocessing module. The invention utilizes the water autonomous patrol platform as the carrier of acoustic detection, locates autonomous movement trajectory planning of array positioning, wirelessly transmits data, and implements autonomous monitoring of large-scale aquaculture facility aquaculture processes, and has the advantages of seamless coverage, autonomous patrol, low cost, insusceptibility of drift influence and the like.

Description

technical field [0001] The invention relates to the technical field of marine fishery, in particular, the invention relates to an autonomous inspection type fishery breeding acoustic monitoring system. Background technique [0002] Marine fish farming is moving to the far sea and deep sea, and the scale of large fences, large net cages and farming ships used in the breeding process is also increasing. For example, developed countries are actively promoting the research and construction of semi-submersible deep-water farming platforms. The Norwegian Salma Group The designed and developed "Ocean Fishing Field No. 1" was put into trial operation in 2018. The main body of the facility has a diameter of 110m and a height of 67m. It is suitable for working in a water depth of 100-300m. Only one staff member can complete the breeding and production of the entire facility; there is also the use of abandoned offshore oil platforms as logistics support workstations to control multiple c...

Problems solved by technology

[0003] Aiming at the above-mentioned breeding platform, it is necessary to carry out real-time and effective monitoring of the cultured fish. Due to the increase in the scale of the breeding facilities, the seawater in some sea areas has low light transmission, and it is almost impossible to complete the seamless monitoring of this breeding area by using the optical video monitoring in the traditional breeding process. ; There are dead spots in the monitoring of the breeding process by using traditional fixed acoustic detection instruments, so it can only be installed at multiple points, and the cost will be greatly increased

At the same time, affected by sea breeze and current, the position of large-scale breeding facilities will drift to a certain extent. For example, the use of global satellite positioning system, Beidou and other satellite positioning will cause great position deviation
