Embodiment Construction

[0028] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] The invention proposes that the floating body is used to sense the wave fluctuation intensity driven by fish shoals, and the feed feeding machine is controlled by calculating the wave fluctuation intensity.

[0030] During specific implementation, the detection of water wave fluctuations is realized by means of a detection device associated with the floating body on the water surface. For example, special detection devices connected to the floating body or placed inside the floating body may be used, including but not limited to infrared detection methods.

[0031] The calculation of water wave fluctuation can be realized through the moving average of different time windows. If a 30-second moving window is used, it should generally be selected between 10 seconds and 1 minute, and empirical values ​​obtained from pre-e...

Abstract

The present invention provides a fish hunger detection method and system based on feeding behavior, which uses a floating body on the water surface to detect water wave fluctuations driven by fish scrambling for food, and controls the feed feeding machine by calculating the intensity of water wave fluctuations; the detection of water wave fluctuations uses the same The detection device associated with the floating body on the water surface is realized. The present invention can meet the requirements of smart fishery, and can carry out aquatic farming more accurately, especially in terms of feed feeding, according to the hunger degree of the breeding objects, to control the feeding of the feed machine, which is useful for saving feed cost and controlling the water quality environment. has an important role.

Description

technical field [0001] The present invention relates to intelligent fishery, and more specifically, provides a fish hunger detection method and system based on feeding behavior. Background technique [0002] Smart fishery requires more accurate aquaculture, especially in terms of feed feeding, how to control the opening time of feed machine feeding according to the hunger degree of the breeding objects is of great importance for saving feed costs and controlling water quality. effect. my country is the largest aquaculture country in the world. The amount of feed required for aquaculture is huge every year. However, due to the inability to accurately determine the hunger and fullness of the aquaculture objects, it causes environmental pollution and increases the cost of aquaculture. Contents of the invention [0003] Aiming at the problems of the prior art, the present invention proposes a fish hunger detection method based on feeding behavior. [0004] The technical sche...
