- 摘要:
- 对沈阳农业大学园艺学院日光温室后墙内侧温度、温室气温、温室地温进行测试和分析,利用传热学理论,以温室热平衡模型为基础,分析了温室后墙内侧温度变化的动态模型,并运用Matlab软件进行非线形回归,求出该模型的参数。结果表明:该模型可较准确地反映温室后墙内侧的温度变化特性,是预测后墙温度的变化,实现自动化控制的基础。为进一步研究日光温室保温特性,实现智能温室前馈控制提供了手段和依据。
- Abstract:
- Temperature of the back wall,soil temperature and air temperature in greenhouse located in College of Horticulture,Shenyang Agricultural University were measuremented and analyzed,based on the model of the thermal balance,using diathermanous theory analyzed the thermal model of greenhouse,using Matlab software proceed nonlinear regression,and fits equation the parameters of this model were obtained.The results showed that this model could accurately reflect the temperature changes of back wall in the greenhouse.The model was the basis for the forecast temperature changes of back wall and control of automation.For the further study insulation properties of greenhouse,achieved intelligent greenhouse feed-forward control provided the means and basis.
