Embodiment 1

[0066] The precise intelligent fish pond feeding of an aquaculture farm includes detection system 1, control system 2, feeding system 3, replenishment system 4 and pond system 5.

[0067] The detection system 1 includes an active sonar 1-1, a fixed electric measuring rod 1-2; the control system 2 includes a calculation unit 2-1, a judgment unit 2-2, and a numerical control host 2-3; the feeding system 3 includes bait feeding Ship 3-1, storage battery 3-2, propeller propeller 3-3, stirring feeder 3-4; supply system 4 includes remote sensing positioning device 4-1, fixed feeder 4-2, bait adding tank 4-3 The pond system 5 includes bottom mud 5-1, water body 5-2, fish 5-3, and pond bank 5-4.

[0068] The device dosing system 3 is fixed on the bait dosing ship 3-1 by screw connection, wherein the battery 3-2 is fixed in the stern cabin, and the battery capacity is 30-40kWh; the propeller propeller 3-3 is fixed on the bait dosing ship 3 -1 stern, the propulsion coefficient is 0.50~...

Embodiment 2

[0110] Others are the same as embodiment 1.

[0111] The fish stock N in the pond system 5 is taken as 800kg / mu, and the calculation result T=105.1kg / mu of the bait dosage of the calculation unit 2-1 is transmitted to the feeding system 3;

[0112] The dosage before use is 200kg / mu, and the dosage after use is 105.1kg / mu, so the reduction is 94.9kg / mu, and the reduction ratio is 47.45%.

[0113] Water quality situation before and after the application of table 2 embodiment 2

[0114]

Embodiment 3

[0116] Others are the same as embodiment 1.

[0117] The fish stock N in the pond system 5 is taken as 1500kg / mu, and the calculation result T=197.1kg / mu of the bait dosage of the calculation unit 2-1 is transmitted to the dosing system 3;

[0118] The dosage before application is 370kg / mu, and the dosage after application is 197.1kg / mu, so the reduction is 172.9kg / mu, and the reduction ratio is 46.73%.

[0119] Water quality situation before and after the application of table 3 embodiment 3

Abstract

The invention discloses an intelligent accurate feeding system and method for aquaculture baits. The system comprises a detection system (1), a control system (2), a feeding system (3), a supply system (4) and a pond system (5), wherein the detection system (1) is used for transmitting dynamically and accurately measured bottom mud thickness data of the pond system (5) to the control system (2), the control system (2) is used to realize intelligent and accurate feeding through calculation according to the bottom mud thickness in combination with parameters such as the fish storage quantity, fish type, the fish growth index, the culture density and the like, and the supply system (4) is used for carrying out scientific regulation, control and feeding on the feeding system (3). According tothe intelligent accurate feeding system, the outstanding problems that the wasting of the baits is serious during the feeding, the feeding operation is poor in accuracy, the bottom mud and a water body are seriously polluted, and the quality of aquaculture products is reduced increasingly are solved, and the energy conservation, emission reduction, restoration of a water environment and environment-friendly healthy sustainable development of the aquaculture are promoted.

Description

technical field [0001] The invention belongs to the fields of energy saving and emission reduction, water body environment restoration and green health, and in particular relates to an intelligent system and method for precise feeding of aquaculture bait. Background technique [0002] With the rapid development of the aquaculture industry, the area and density of aquaculture are constantly increasing, and the workload of feed feeding has also increased greatly. Simple manual feeding has a lot of work and relatively low efficiency. After field research and inspection of many breeding areas in the Hongze Lake breeding area, it was found that there was a considerable imbalance between the amount of bait fed, the output of aquatic products, and the increase in sediment thickness. The research data show that the bait added in the past only has a product conversion rate of 14.3% to 15.2%, and the remaining 11.5% to 13.4% sinks into the bottom mud, and the bait lost in the water en...
