东北夏季Venlo型温室温度的时间预测模型构建与检验

Building and Testing of the Time Prediction Model of Venlo-Type Glasshouse Temperature in Summer in Northeast of China

温室温度的合理预测是夏季温度控制的重要根据。通过实验设计并测量温室内温度及其影响因素的数据,并运用时间序列分析方法对数据异常点处理及缺失值补足,并对无遮阳三种降温状态下的各变量分别进行平稳性检验,建立了三种状态下的时间序列预测模型,结果显示预测数值与实际数值吻合良好,为东北夏季Venlo型玻璃温室的温度控制提供了理论依据。

A reasonable estimate of greenhouse temperature was an important basis for controlling the summer temperature.Three time series prediction models were built through design of experiment and measuring data of greenhouse temperature and other influencing factors, applying time series analytical method to dispose anomalous point and complement the missing data, and then using stationarity test to inspect each variable under three cooling status without sunshade. The results showed that the prediction data could correspond to the measured data.The research provided a theoretical basis for the temperature control of Venlo-Type glasshouse in summer in Northeast of China.
