Underwater protection system for coastal aquaculture and operating method therefor

Abstract

The invention provides an underwater protection system for coastal aquaculture and an operating method therefor. The protection system comprises monitors (100) and a data center (200), wherein the monitors are fixedly arranged on underwater culture net cages (300) or directly fixed in water in a suspended manner, and wireless communication modules are correspondingly arranged on the monitors and the data center separately so as to achieve wireless communication connection between the monitors and the data center; and the data center further comprises a warning module (220) and controls the warning module to alarm when wireless signals received from the monitors by the data center are in line with alarm conditions. According to the underwater protection system and the operating method therefor, multipoint, real-time and uninterrupted offshore net cage monitoring and automatic alarming are achieved through wireless communication connection on the basis of a submarine sound signal passive detection principle, and thus, the real-time monitoring and warning of aquaculture net cages of an entire seashore is achieved; and the protective range is large, the efficiency is high, the safety and reliability are good, and the cost is low.

Description

technical field [0001] The invention relates to an underwater protection system for coastal aquaculture realized by the principle of acoustics, and belongs to the technical field of marine fishery and animal husbandry production equipment and marine surveying instrument manufacturing. Background technique [0002] With the deepening of marine development, marine fishery production has gradually changed from fishing to aquaculture. Cage aquaculture is especially common in my country, and it is widely distributed near the coast. Usually the cages are arranged 3-5m below the water surface, because it is not easy to be found, so it is very easy for boats, swimmers and cages to be entangled; at the same time, because the cage culture is far away from the shore, it is not easy to manage. Prone to poaching and poaching. On the one hand, these situations will cause great losses to farmers, and on the other hand, they will also have an impact on normal sailing, and even threaten the...

AI Technical Summary

Problems solved by technology

[0004] 1. The protection range is small: due to the limited height of flag flags and flashing lights, generally no more than 1.5m, and the number is small, it is difficult for sailing ships to find them at a long distance; when they are found at close range, effective evasion measures cannot be taken

[0005] 2. Low protection efficiency: flags and flashing lights are warning signs, which cannot realize the alarm function, and the real-time alarm cannot be realized when the ship is cruising.

[0006] 3. Low safety and reliability: the flashing light used at night is close to the navigation mark light of the channel, which may mislead the ship into danger

Cages or shark-proof nets may cause entanglement accidents with ships and underwater personnel, resulting in large losses to cages and ships, and even endanger
