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] like 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 module...
