该系统采用传感器测量和显示温室内温度及湿度变化，利用计算机和外围电路控制温室内天窗、风机、遮阳网、湿帘和恒温阀等执行机构自动运转，完成温室环境的自动控制，确保温室中所种的植物能获得最佳的生长环境空间。同时通过一条总线将每个温室的控制装置连接起来送到监控计算机，构成互联网集中监控系统。系统基于LabVIEW可视化图形编程语言，利用其外挂的PID工具包，实现了图形化界面设计，并且控制精度比较高。

The system uses a sensor to measure and display the temperature and humidity changes in the greenhouse,using a computer and a peripheral circuit control greenhouse implementation of the sunroof,fan,shading nets,wet curtain,and a thermostatic valve bodies within the automatic operation of the automatic control of the completion of the greenhouse environment,to ensure that the greenhouse plant species can get the optimum environment space.Through a bus control device for each greenhouse connected to the monitoring computer,the Internet constitutes a centralized monitoring system.The system is based on graphical programming language LabVIEW visualization and PID tools package,the graphical interface design,and high control accuracy.
