摘　　要：本文提出了基于水体溶解氧含量变化的增氧机控制系统,该系统根据传感器传回的实时溶解氧数据,通过方差和标准差算法判断一定可配置时间内水体中溶解氧含量变化。当变化幅度达到配置阈值时,控制增氧机的开启和关闭。该系统适用于网络环境较差和低投入的水产品养殖企业,使得这些企业在不需要集成大规模高成本网络系统的背景下,精确控制水产品养殖水体环境中溶解氧的数值,达到快速精细化、数字化养殖的程度。This paper designed the control system for Aerator running with a variation in dissolved oxygen. This system can use the variance and standard difference algorithm to estimate a variation of dissolved Oxygen in some time according to the real-time data from the sensor. When the variation went up to the configured thresholds, Aerator tuned on or out. The system was applied to aquaculture enterprises with a poor network and low input to make them achieve a rapid refined digital aquaculture with fewer or without costs.
