Problems solved by technology

However, current recirculating aquaculture systems usually adopt a rated rate circulating water strategy, which does not consider the impact of fish behavior on bottom sewage discharge, and there are relatively few research applications on the impact of fish behavior on the flow field and the determination of flow velocity

Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings.

[0045] refer to figure 1 , is the variable-speed flow intelligent control system based on fish school behavior and bottom sewage characteristics of the present invention, including a circulating aquaculture pond 1, a circulating water treatment system 2, a feeding machine 3, a high-definition waterproof camera 4, a computer 5, and a PLC controller 6 , frequency conversion water pump 7;

[0046] A circulating water treatment system 2 is installed outside the circulating water aquaculture pool 1. The circulating water treatment system 2 transports the aquaculture wastewater to the circulating water aquaculture pool 1 after a series of operations such as filtration, sterilization, and oxygenation, which greatly improves the efficiency of water resources. utilization rate;

[0047] The feeding machine 3 and the high-definition waterproof camera 4 are all installed direct...

Abstract

The invention discloses a variable-flow intelligent control system based on fish school behaviors and bottom pollution discharge characteristics. The system comprises a circulating water culture pond, a circulating water treatment system, a feeder, a high-definition camera, a variable-frequency water pump, a computer, a PLC and the like. The system mainly utilizes a machine vision technology and a computational fluid mechanics simulation technology to analyze and evaluate sludge discharge at the bottom of the culture pond, so as to formulate a variable-speed flow strategy. The variable-flow intelligent control system is simple in structure, the method is accurate, simple and convenient, the intelligent variable-flow system is suitable for a recirculating aquaculture mode, and the problems that in an existing recirculating aquaculture system, bottom sludge is difficult to discharge, water flow dead zones exist, water quality becomes poor, and growth welfare of fishes is affected can be effectively solved.

Description

technical field [0001] The invention belongs to the field of industrial circulating water aquaculture flow rate control, and relates to a variable-speed flow intelligent control system based on fish shoal behavior and bottom sewage characteristics, especially to a high-density circulating aquaculture that integrates fish shoal behavior and bottom sewage characteristics Variable speed flow intelligent control system. Background technique [0002] Industrialized recirculating aquaculture is a breeding method with the characteristics of high benefit, high density, and less water consumption. It is gradually accepted by people and is more and more applied to production practice. The key to recirculating aquaculture is to ensure good water quality in the aquaculture pond, which plays an important role in the health of the cultured organisms. The effective removal of sludge at the bottom of the aquaculture pond, which is mainly composed of residual bait and feces, is the core of ...
