基于虚拟仪器的温室环境监控系统的总体架构方案

随着计算机的发展与普及,温室环境控制自动化程度也有了较大的提高。运用一定的工程措施,来改善作物生长的环境条件,创造出适合作物生长的微气候条件,并将现代计算机技术引入农业温室,实现农业温室的自动控制。结合我国现阶段温室发展的主要特点及温室内环境因子对作物产量和品质的重要性,以计算机、数据采集卡、传感器等作为硬件基础,LabWindows/CVI为软件基础,研究设计了"基于虚拟仪器的温室环境因子监控系统"的总体架构。该方案将虚拟仪器应用到温室环境因子的检测,以软件为核心,具有强大的数据存储和分析处理能力,并可提高分析精度;良好的虚拟仪器软面板增强了与外界的交互性;系统易于扩展,可灵活满足用户的测试要求。

Overall Construction on the Environmental Monitor and Control System of Greenhouse Based on Virtual Instrument

With the development and the popularization of computer,the automatic level of the greenhouse environment control has been largely enhanced.Utilizing the certain project measures can improve the environmental conditions of crop growth and create the adaptive micro-climatic conditions for crop growth.The modern computer technology was introduced to realize the automatic control of agricultural greenhouse.In this article,according to the main developmental characteristics of the present day greenhouse and the importance of environmental factors of greenhouse to crop yield and quality,the overall construction of "greenhouse environment factor supervisory system based on the virtual instrument " was designed with the hardware foundation of the computer,the data acquisition card,the sensor and so on and the software foundation of LabWindows/CVI.In this system,virtual instrument was applied to monitor the environment factors of the greenhouse.The software,which not only had strong abilities of data storage and data analysis,but also could improve the analysis precision,was the core of the system.The interaction between the system and outside could be strengthened by the panel of virtual instrument and the system was easy to be expanded so that it was flexible to satisfy the users' needs.
