Circulating water culturing water quality intelligent early warning device and method based on fish swarm behavior space-time characteristics

Abstract

The invention discloses a circulating water culturing water quality intelligent early warning device and method based on fish shoal behavior spatio-temporal characteristics. The device comprises a circulating water culture pond, a circulating water treatment system, a depth camera, an alarm, mobile equipment, a display and a server. The device mainly utilizes a computer vision technology and an image processing technology to construct a motion influence diagram capable of reflecting water quality change characteristics, and performs water quality abnormity early warning in time under the condition of not influencing normal growth and development of fishes through quantitative analysis of spatiotemporal characteristics of fish shoal behaviors. The device is simple in structure, the method is accurate, simple and convenient, the intelligent water quality early warning device and method can effectively solve the problems that existing common water quality detection equipment is not high in accuracy and low in reliability, it is guaranteed that the water quality of the aquaculture water body is within the adaptive range in a non-invasive mode, and fish aquaculture welfare is facilitated.

Description

technical field [0001] The invention relates to the technical fields of water quality detection and fish behavior analysis, in particular to an intelligent water quality early warning device and method for circulating aquaculture based on the temporal and spatial characteristics of fish behavior. Background technique [0002] With the rapid development of economy and society and the significant improvement of people's living standards, people's demand for fish protein is increasing, and my country's aquaculture industry is showing a trend of vigorous development. In aquaculture, especially in intensive recirculating aquaculture, the quality of water directly affects the growth and development status and growth welfare of aquatic animals, is related to the quality of aquatic products, and also determines the output and economic benefits of the aquaculture system. Real-time monitoring of dissolved oxygen, pH value, temperature, ammonia nitrogen and other water quality paramete...

AI Technical Summary

Problems solved by technology

But so far, few scholars have conducted research on intelligent early warning of water quality based on the analysis of fish behavior information, and the relevant water quality research has not been able to integrate multiple water quality parameters, which is not representative, and most of them are based on the analysis of fish behavior information. The tracking of individual targets in the group, this kind of water quality research based on individual target tracking technology is not suitable for high-density intensive recirculating aquaculture
