Intelligent feeding system and method for fish culture

Abstract

The invention discloses an intelligent feeding system and method for fish culture. The intelligent feeding system comprises a float sensor, a controller, a material containing hopper and a material distributing device, the material containing hopper and the material distributing device are installed above the culture water surface through a support, the material containing hopper is used for containing fish feed, a discharging port is formed in the bottom of the material containing hopper, and an electromagnetic valve is arranged at the discharging port to control opening and closing of the discharging port; the lower part of the discharging port is in butt joint with an inlet of the distributing device, and the distributing device is used for evenly distributing received fish feed to a water area where the distributing device is located; the output end of the float sensor is connected with the controller, and the controller is connected with the electromagnetic valve; and the float sensor floats on the water surface and is used for sensing the magnitude of vibration brought by ripples on the water surface and sending an electric signal to the controller when the vibration reaches a certain degree, and the controller controls opening and closing of the electromagnetic valve according to the received electric signal of the float sensor in combination with a preset rule. According to the intelligent feeding system for fish culture, intelligent control of feeding is realized, feeding drop points are uniform, and the culture cost and workload are saved.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to an intelligent feeding system and method for fish farming. Background technique [0002] In the process of fish farming, it is essential to add fish feed quantitatively according to the stage of fish growth. At present, when fish are fed, artificial feeding is mostly adopted. Manual feeding is mostly based on experience. According to the growth stage, type and number of fish, the fish feed is put in in a timely and quantitative manner, and artificial feeding is usually carried out by throwing or sprinkling. When feeding by throwing, the thrown fish The feed forms a curve and falls into the water surface of the fish pond from near to far; when feeding by sprinkling, the sprinkled fish feed forms an arc and falls into the water surface of the fish pond from near to far. Whether it is through throwing or sprinkling, it is difficult to control the strength of artificial feedin...

AI Technical Summary

Problems solved by technology

Whether it is through throwing or sprinkling, it is difficult to control the strength of artificial feeding. When the force is too large, the fish feed will fall too scattered on the water surface of the fish pond, even beyond the scope of the collective feeding of fish; if the force is too small, the fish feed will fall on the water surface of the fish pond. It is easy to be lumpy, because the fish feed falls into the fish pond water surface unevenly, so that the fish are prone to scramble during the feeding process. At the same time, with the continuous expansion of the breeding scale, the water area gradually increases. The intensity is also increasing, the labor cost is gradually increasing, and the efficiency is gradually failing to keep up with the actual requirements
