The invention belongs to the field of shrimp culture, and discloses a bait tray dynamic monitoring method, which comprises the following steps: firstly, arranging a liftable bait tray, arranging a liquid level sensor on the bait tray, arranging a hydrophone near the bait tray, and enabling the bait tray to sink into the water surface of a preset shrimp pond area; secondly, enabling the bait tray to hover at a preset feeding position under the water surface through a collection signal of a liquid level sensor, collecting shrimp feeding audio in a feeding area containing the bait tray for a first preset time period through a hydrophone, and obtaining a feeding comparison frequency range based on the shrimp feeding audio in the first preset time period; and finally, continuously collecting shrimp ingestion audio frequency through a hydrophone until the frequency of the shrimp ingestion audio frequency is within an ingestion comparison frequency range within a continuous second preset time period, enabling the bait tray to rise, and enabling the bait tray to hover at a preset observation position under the water surface through a liquid level sensor, so as to obtain the amount of residual bait in the bait tray. The invention further discloses a bait tray dynamic monitoring system.
本发明属于虾类养殖领域,公开了一种饵料盘动态监测方法,首先,设置可升降的饵料盘,在饵料盘上设置液位传感器,在饵料盘的近旁设置水听器,使饵料盘沉入预定虾塘区域水面;其次,通过液位传感器的采集信号,使饵料盘悬停在水面下的预定摄食位置,通过水听器对含有饵料盘的摄食区域内的虾类摄食音频进行第一预定时间段的采集,基于第一预定时间内的虾类摄食音频得到摄食比对频率范围;最后,通过水听器持续采集虾类摄食音频,直至虾类摄食音频的频率在持续第二预定时间段内均在摄食比对频率范围之内时,饵料盘上升,并通过液位传感器使得饵料盘悬停在水面下的预定观察位置,从而得到饵料盘内的残余饵量。本发明还公开了一种饵料盘动态监测系统。
