Embodiment Construction

[0031] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0032] The basic principle of the invention is the principle of echo detection. Compared with light waves and electromagnetic waves, sound waves have less propagation loss and longer propagation distance in water, and are the best means for detecting and identifying underwater small targets. During echo detection, the transducer converts the electronic signal into a sound wave pulse and emits it into the water. When the sound wave encounters an obstacle in the process of propagating in the water, because the acoustic impedance rate of the object is different from that of the water medium, the object will scatter the incident sound wave. And reflection, part of the sound signal backscatters to the ...

Abstract

The invention discloses a feeding control system and method for fish culture. The system comprises a split beam transducer, a feeding unit and a signal collecting, processing and control unit, wherein the split beam transducer is used for converting acoustic waves and electric signals and transmitting and receiving the acoustic waves in water, the feeding unit is used for receiving a control instruction to feed the cultured fishes, the signal collecting, processing and control unit is used for receiving an echo signal which is collected by the split beam transducer, and converting the echo signal into echo images through phase difference detection and wave detection, and the weight of single fish and the total weight of a fish school in the feeding water area are respectively calculated after target identification and acoustic wave image processing, so the feeding amount is adjusted. The system and the method have the advantage that the growth change of the fishes in the feeding water area can be monitored, and the feeding amount is adjusted in real time, so the waste on culture baits is reduced.

Description

technical field [0001] The invention relates to information-based fish farming technology, and more specifically relates to a feeding control system and method for fish farming. Background technique [0002] With the continuous expansion of the scale of intensive aquaculture, the aquaculture process is increasingly dependent on artificial feeding of compound feed, and the cost of aquaculture bait in aquaculture accounts for an increasing proportion of the entire aquaculture cost. In the process of aquaculture, the level of breeding bait feeding technology directly affects the conversion rate of aquaculture bait and the breeding effect. The important basis for feeding is the growth and development of fish schools in the feeding waters. The number and weight of fish schools change in real time. Only by mastering the growth and development of fish schools can we adjust the feeding amount in a targeted manner to meet the requirements of precise feeding. [0003] At present, th...
