Problems solved by technology

This not only consumes a lot of manpower and time, it is difficult to spread the feed evenly; it is also impossible to accurately control the amount of feed
Insufficient feeding will limit the growth of shrimp, and excessive feeding will cause waste of feed, further pollute the water quality of shrimp ponds, and easily cause diseases
In addition, the artificial breeding method cannot meet the needs of larger-scale integrated breeding, which limits the development of the industry

specific example

[0067] As a specific example, S2 specifically includes:

[0068] S201: Obtain the standard shrimp eating sound signal collected by the acoustic sensor when it is pure and without interference, and establish a standard characteristic library of shrimp eating sound;

[0069] figure 2 and image 3 The shrimp standard feeding signal-time domain diagram and the shrimp standard feeding signal-frequency domain diagram respectively.

[0070] see figure 2 and image 3 It can be seen that the standard sound of shrimp eating is similar to a single pulse signal in the time domain, the signal duration range is 8-10ms, the frequency range is 2-10KHz, and there is a maximum spectral peak in the range around the frequency of 5KHz, and the intensity is about -78dB.

[0071] S202: Carry out correlation detection, identification and calculation between the environmental acoustic signal collected by S1 and the standard shrimp eating acoustic signal in the feature library;

Abstract

The invention provides an intelligent feeding method and system for shrimp culture based on acoustic detection. The method comprises the following steps of: acquiring an environmental acoustic signal after feeding; according to the environmental acoustic signal, detecting to obtain a shrimp feeding acoustic signal; extracting an effective feeding acoustic signal interval and feeding quantity according to the shrimp feeding acoustic signal; and obtaining the hunger degree according to the feeding acoustic signal interval and the comparison result of the feeding quantity and the feeding acoustic hunger degree threshold value. According to the method, intelligent feeding can be achieved in the growth period of shrimps according to needs, the breeding cost is lowered, meanwhile, healthy growth of the shrimps is better facilitated, and the risk of the shrimp breeding industry is reduced.

Description

technical field [0001] The invention relates to the technical field of shrimp farming, in particular to an acoustic detection-based intelligent feeding method and system for shrimp farming. Background technique [0002] At present, in most shrimp farming factories, the feeding of shrimp is still carried out by manual experience. Doing so not only consumes a lot of manpower and time, it is difficult to spread the feed evenly; it is also impossible to accurately control the amount of feed. Insufficient feeding will limit the growth of shrimp, and excessive feeding will cause feed waste, further pollute the water quality of shrimp ponds, and easily cause diseases. In addition, the artificial breeding method cannot satisfy larger-scale integrated breeding, which limits the development of the industry. [0003] Aiming at the deficiencies in the prior art, the present invention provides an intelligent feeding method and system for shrimp farming based on acoustic detection. It ...
