Embodiment Construction
[0024] like figure 1 As shown, the circulating aquaculture floating bait automatic feeding device of the present invention includes a bait feeder and a CCD camera 1, and the CCD camera 1 is used for real-time collection of image data of the number of floating baits. The uppermost part of the bait throwing machine is a hopper 2, the middle part is a vibrating feeding mechanism 3, and the lowermost part is a base 10. The CCD camera 1 is located at the top right of the hopper 2 and is connected to the hopper 2 through a connecting rod 17 . Adjust the position of the CCD camera 1 so that it collects the floating bait 13 floating on the water surface. The floating bait 13 forms a circle with the closed protective material fence 14 floating on the water surface. The camera 1 collects the floating bait 13 inside the guard fence 14 against the inside of the guard fence 14 . The guard fence 14 is used to protect the floating bait 13 and prevent the floating bait 13 from drifting away...

The invention discloses an automatic floating bait feeding method and device for recirculating aquaculture. The device comprises a bait feeder and a CCD camera. The method comprises the steps that the CCD camera is started to monitor the residual floating bait amount condition on the water surface, after a fish shoal takes baits for t seconds, the residual floating bait amount S on the water surface at the moment and the current fish shoal bait taking speed k are firstly calculated, then the current bait feeding speed y and the bait feeding working time r are calculated according to a BP neural network model (y,r)=(S,k), and the current bait feeding speed y and the bait feeding working time r serve as the optimal control parameters to control the bait feeder to perform automatic bait feeding. Accordingly, the floating bait digestion condition of the fish shoal can be fed back in time, precise feeding is achieved, destruction to the water environment due to overmuch single-time floating bait feeding is prevented, and the cyclic utilization efficiency of water is improved.
Description
technical field [0001] The invention relates to the field of fish farming automation, in particular to a floating bait automatic feeding device, which is used in high-density industrial fish farming in places with high requirements for water environment and automation. Background technique [0002] Aquaculture has moved from manual feeding to automatic feeding. Automatic floating bait feeding machine is one of the important components of aquaculture. Compared with manual throwing of floating bait, automatic bait feeding is the main means to improve the utilization efficiency of floating bait and control the cost of farming. The document with the Chinese patent application number 201110340825.4 discloses an automatic bait casting method, which uses a video acquisition system to collect water surface information, transmits it to the host computer system through a wireless network, and then realizes real-time monitoring of remote data through the host computer system. The metho...
