Embodiment Construction

[0025] Such as figure 1 As shown in Figure 5, the device of the present invention controls the work of the throwing motor according to the behavior of the fish, and the specific control work flow chart is as follows figure 1 , where the daily feeding time period is T 1 ,T 2 ,T 3 . The duration of each motor startup is T seconds; the average output per second of the throwing system is P grams; the motor can be started up to n times a day; the maximum amount of bait per day is Q=nTp where Q is based on the maximum daily demand of fish The amount is determined.

[0026] For example, the motion sensor of the acceleration sensor distinguishes the mechanism of fish collision behavior, and the control system belongs to the closed-loop control system. When the trigger lever of the fish luring device swings under the influence of various external factors, the travel switch will be triggered, and the system will judge whether it is caused by the touch of the fish body according to ...

Abstract

The invention discloses a fish culture feeding device comprising a bait box, a bait casting plate driven by a casting motor, an integrated control box, float balls and at least one trigger rod connected with the integrated control box through an interchangeable universal head. The trigger rod is provided with a thin film pressure sensor. An acceleration sensor and an integrated control module are arranged in the integrated control box. The integrated control module is composed of a control circuit comprising a single-chip microcomputer. Foraging touch behaviors of fish are determined by the acceleration sensor and the thin film pressure sensor, and the results are fed back to the single-chip microcomputer. With the control of the single-chip microcomputer, the bait casting motor casts baits in a timed and quantified way, such that bait casting adequacy and uniformity are realized. Fish individual growing condition is uniform, intraspecific cannibalism possibility is reduced, and survival rate is improved. The control device and control method realize timed and quantified uniform bait casting based on fish feeding habits.

Description

technical field [0001] The invention belongs to the technical field of fish farming equipment, and in particular relates to a fish farming bait feeding device and a bait feeding method. Background technique [0002] my country's offshore cage culture has a large scale, and the traditional feeding method is mainly artificial feeding, which requires a large labor force. In recent years, labor costs have gradually increased, and it is an urgent need to use special bait feeding equipment instead of manual feeding. [0003] Some carnivorous fish with high breeding costs and high economic value, such as large yellow croaker, are highly predatory. At present, they are mainly cultured in artificial cages. Kill each other, reduce the survival rate of fish, and cause economic losses. [0004] In addition, the traditional artificial feeding method often feeds bait based on personal experience. Too much or too little feeding is not good for fish breeding. When the bait is insufficient...
