摘要
针对浑水海域网箱养殖中的投饲量控制问题,提出了一种采用回声探测方法进行智能投饲监控的系统原理及软硬件设计。在网箱底部安装一套收发合置的回声探测声纳,监测通过网箱饲料反射的声信号能量值,将其作为反馈量来调整饲料流量,使得过剩饲料维持在预设量,以实现智能饲量控制。为简化投饲监控系统并降低成本,可采取1套回声探测系统同时监控4个网箱的设计,并将各个监控节点组成WLAN后接入公网,以实现大型网箱养殖场的远程智能投饲监控。
To control feeding in muddy water cage culture,an intelligence feeding monitor and control system based on echo detection is proposed.In this system,sonar with both transmitter and receiver was placed under a cage.Feed passed through the cage will be detected as echo signal energy,which intensity is a feedback for feed flow control,so as to ensure intelligence feeding.To simplify feeding system and cost,four cages shared a sonar detection device.All monitor nodes are connected by WLAN and then access into internet for centralized remote control in large scale cage culture field.
