Fishery culture monitoring system and method based on fish collection class acoustic monitoring and positioning

Abstract

The invention provides a fishery culture monitoring system and method based on fish collection class acoustic monitoring and positioning. The system comprises a culture facility, an aquatic independent patrol inspection platform, a plurality of positioning arrays and a control center, wherein the culture facility is a cuboid; the plurality of positioning arrays are independently fixed on differentpositions of the culture facility; the control center is in communication connection with each positioning array; and the aquatic independent patrol inspection platform and the control center are incommunication connection and are arranged in the culture facility. By use of the fishery culture monitoring system and method based on the fish collection class acoustic monitoring and positioning, anunmanned vehicle is adopted to serve as an acoustic detection carrier, and the unmanned vehicle is positioned through a detection signal, the trajectory planning of the unmanned vehicle is finished through positioning information, an acoustic signal combines detection and positioning functions into a whole, so that the bearing capacity of the unmanned vehicle is greatly saved, the integration level and the stability of equipment are improved, and equipment cost is lowered.

Description

technical field [0001] The invention relates to the field of marine fishery, in particular to a fish farming monitoring system and method based on acoustic monitoring and positioning of fish collection. 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 ...

AI Technical Summary

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
