An autonomous inspection type fishery breeding acoustic monitoring system

Abstract

The invention discloses an autonomous inspection type fishery breeding acoustic monitoring system, which includes aquaculture facilities, a water surface positioning detection platform and a water surface platform, and the water surface positioning detection platform and the water surface platform are connected through a wireless communication protocol; the water surface positioning detection platform includes a water surface autonomous inspection platform and positioning base array; the autonomous inspection platform on the water includes the fish detection sensor module, the fish detection signal processing module, the positioning module, the main control module, the communication module and the main control module, the positioning module, the communication module and the fish detection signal processing module to provide work voltage battery pack. The invention uses the autonomous inspection platform on the water as the carrier of the acoustic detection, the autonomous movement trajectory planning of the positioning array positioning, and wireless data transmission to complete the autonomous monitoring of the breeding process of large-scale breeding facilities, with seamless coverage, autonomous inspection, and low cost. , Not affected by drift and so on.

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
