摘要:

为实现设施黄瓜温室风口开度大小的精准控制,对温室内温度变化趋势进行了预测研究。将温室风口开度大小状态和温室内外各环境因子作为输入因子,利用逐步回归的方法构建温室温度预测模型,模型决定系数R2 最小为0.941。采用主成分分析方法建立黄瓜长势关系表达式,然后利用Lasso回归构建基于环境因子的设施黄瓜生长模型。将温室温度预测模型与设施黄瓜生长模型相结合,最终构建了设施黄瓜温室专用风口控制模型,实现了温室风口开度大小的自动控制,提升了设施黄瓜温室的智能化管理水平。

关键词: 温室风口, 逐步回归, 预测, Lasso, 自动控制

Abstract:

To precisely control the opening size of the cucumber greenhouse air vents in facilities, this paper studied prediction of temperature change in greenhouse. Taking the opening size and greenhouse tuyere both inside and outside environment factor as input factors, temperature prediction model was built by the method of stepwise regression.The results showed that the minimum determination coefficient R2 was 0.941. Principal component analysis was used to establish the expression of cucumber growth potential, and Lasso regression method was used to build the greenhouse cucumber growth model based on environmental factors. Finally, the temperature prediction model was combined with the cucumber growth model to construct special tuyere control model, which realized the automatic control of the tuyere opening size of the greenhouse, and then improved the intelligent management level of the cucumber greenhouse.

Key words: greenhouse tuyere, stepwise regression, predict, Lasso, automatic control
