摘要我国一直是一个农业大国。然而，由于农村土地逐渐城市化、工业化，以及国土跨度大，季节气候种类多等方面的因素，我国的农业发展仍受到很大的限制。温室能够在不适合农作物生长的季节或者地域环境中给农作物提供良好的生长环境。在温室环境调控中，温室动态环境模型库是必不可少的部分。通过温室动态模型库，可以实时了解温室内外部环境，植物长势，为植物的提供更为适宜的成长发育环境，提高农业生产效率与质量。83848
本文基于LabVIEW软件，对温室动态模型库进行了相关研究。在前人的基础上，以Venlo型玻璃温室为例，分析典型Venlo型温室的结构材料以及温室内部的各类调节机构对温室降温的影响程度，构建夏季温室降温动态模型，建立了相关温室动态模型库；基于LabVIEW软件设计编写出了温室动态模型库人机交互界面，即温室动态环境预测软件。在界面中可以输入温室结构、地理位置、作物、室内外初始环境、调控机构开启状态等各类参数并预测出经过调控稳定后温室的室内温度，同时选择四种典型的温室降温调控方案进行了相关模拟验证对比，得出了夏季温室降温的最佳调控方案。

Abstract China has always been a big agricultural country。 However, due to the gradual urbanization and industrialization of rural land, and the large size of the land, the development of agricultural economy in our country is still restricted by many factors。 Greenhouse can provide a good environment for the growth of crops in the season or geographical environment which is not suitable for crop growth。In the regulation of the dynamic environment of the greenhouse, the model base of the greenhouse dynamic environment is an indispensable part。 Through the greenhouse dynamic model library, we can understand the internal and external environment of the greenhouse and the plant growth in real time。 A more suitable growth environment for the plant can be provided and improve the efficiency and quality of agricultural production can be improved。
In this paper, the dynamic model of greenhouse was studied based on the LabVIEW software。 On the basis of the former research,use Venlo type glass greenhouse in for example,analysis the structure and materials of the typical Venlo type greenhouse and the effect of various regulating agencies on the greenhouse cooling and build dynamic model for greenhouse in summer for cooling established greenhouse dynamic model bank; The human-computer interaction interface of greenhouse dynamic model is designed based on the LabVIEW software。 Various parameters of the greenhouse and predict the indoor temperature of the greenhouse can be input in the interface。 At the same time, the relevant simulation analysis of four typical control schemes of greenhouse cooling is carried out, and the optimal control scheme of summer greenhouse cooling is obtained。
