摘要
主要研究养殖池内水温控制模型的建立与误差分析。综合考虑养殖池大小、进出水口数、分布、水温、气温等因素,通过必要合理的简化和假设,根据热量平衡方程建立水温和电机放水时间的关系模型,并采用可编程逻辑控制器(PLC)实现程序控制。综合分析模型假设、数据采集和处理等诸方面引起的误差,计算出最佳的电机运行时间,实现节能高效的水温控制。
The water temperature control model of holothurian aquaculture and the model error are analyzed in this paper.Considering all kinds of factors,such as the cubage of the pond,the number and the distributing of the water inlets and outlets,the temperature of the water and the environment,we establish a mathematical model about the relationship of the temperature of wa- ter and the time to inject underground water into the pond according to the heat balance equation in the premise of making necessary simplification and assumption.Then use PLC to implement the control.At last,analyze the error brought by the mathematical model,the program and the data collection and processing to get the optimal parameter for the efficient control.
