摘要： 针对10万吨级深远海养殖工船多养殖舱集约化、自动化控制需求，设计了一套可远程集中控制、定量、定速作业并进行故障诊断的自动投饲系统。采用下料机转速开环控制结合饲料容重的方法来计算投饲重量，减少船舶横摇纵倾对称重传感器测量精度的影响；采用管路压力PID控制方法降低气力输送在不同管路长度对出口饲料速度和破碎率的影响。经工程试验验证，投饲误差小于为2.5%，平均破碎率为0.49%。远程自动化控制及故障诊断可大幅提高工作效率，是一套可推广应用于大型移动式工船舱养模式的干式颗粒饲料投饲系统。

Abstract: Aiming at the requirements of intensive and automatic control of multiple tanks on a 100 000ton deep-sea aquaculture engineering vessel an automatic feeding system was designed, which can be remotely controlled centralized, quantified, fixed speed, and fault diagnosis. To reduce the influence of ship roll and trim on the measuring accuracy of the load cell, the feeding weight is calculated by using the method of open-loop control of the speed of the feeder and feed bulk density; The pipeline pressure PID control method was used to reduce the feed breakage rate in pneumatic conveying with different pipeline lengths. The experimental results showed that the feeding error was less than 2.5% and the average breakage rate was 0.49%. It is a set of dry pellet feed feeding systems that can be popularized and applied to large mobile engineering ship feeding modes.
