基于PLC的温室智能控制系统研究开发

Greenhouse Temperature Control System Based on PLC

近年来,我国农业技术水平在规模化、集约化、科学化、设施面积和设施水平等方面有很大的提高。但在温室各种设备的控制上,仍然是以人工控制为主,智能控制只起到辅助作用或者根本没有被采用,其原因是温室的智能控制很难建立精确的数学模型,导致控制方法复杂,这使得采用以往以点动为主的各种控制方式很难得到预期的效果。该研究选择可编程控制器(PLC)控制作为控制核心,建立了一个基于PLC的并具有人机交互界面温室智能控制系统。

China have achieved significant improvement in scale,intensity,scientificity,facility area,facility standard and so on. However,in respect of the glasshouse control on various equipment,it mainly relies on artificial control. Intelligent control either plays an auxiliary role or not even get utilized. Glasshouse intelligent control can hardly establish accurate mathematical model,which makes control method ineffective. As a result,it is difficult to get the expected results by using former control modes. Adopting PLC as control core,a greenhouse temperature control system based on PLC was established.
