Embodiment Construction

[0053] The technical solution of the present invention will be further explained by the following examples, but the protection scope of the present invention is not limited in any form by the examples.

[0054] Such as figure 1 , figure 2 As shown, the automatic bait feeding method is mainly divided into three steps: underwater acoustic monitoring, threshold detection and feeding control. The threshold detection includes two parts: background noise threshold detection and feeding characteristic signal threshold detection, which are used as the judgment of fish eating status. in accordance with.

[0055] 1. Underwater Acoustic Monitoring

[0056] A non-directional hydrophone is arranged on the side of the bait outlet to monitor the environmental sound signal in real time.

[0057] 2. Threshold detection

[0058] The hydrophone is connected to a data processing module and a short-term data storage module; the signal collected by the hydrophone enters the data processing mod...

Abstract

The invention relates to a method for automatically throwing bait according to needs based on acoustic monitoring, and belongs to the technical field of acoustics. The method comprises the steps that a non-directional hydrophone is arranged at the side of a bait outlet, and an environmental sound signal is monitored in real time; a hydrophone is connected with a data processing module and a short-time data storage module; signals collected by the hydrophone enter the data processing module to obtain a background noise energy level and a feeding characteristic signal energy level, and a processing result is stored in the storage module and used for threshold detection of background noise and feeding characteristic signals; according to the magnitude of the background noise higher than the threshold value and the energy value of the characteristic signals, a bait feeding control signal nc is output, nc is equal to 0-ncm, the numerical value corresponds to the opening and closing size of a bait feeding switch, 0 is full closing, and ncm is full opening; and the purpose of automatic control of bait throwing is achieved.

Description

technical field [0001] The invention belongs to the technical field of acoustics, and in particular relates to a method for automatically dropping fishing baits on demand based on acoustic monitoring. Background technique [0002] Fish farming is of great significance in providing food supply economically, making up for the shortage of marine fishing, and maintaining ecological balance. Fish breeding is an important part of fish farming. The common method at present is to feed fish regularly and quantitatively. The weak point of this way is: 1, depends on the experience of breeder. For how long each fish needs to be fed once, and how much amount to put in at one time, the breeder needs to explore for a long time and obtain through many experiments; 2, it is not conducive to popularization. The food intake of fish will vary with seasons and fish ages, and the experience of farmers has great limitations and cannot be promoted; 3. It is impossible to accurately determine the...
