摘　　要：水资源匮乏是当今面临的重大问题之一,农业生产用水量大更突显节水农业的重要性,因此温室灌溉自动化成为一个研究方向。设计了一个可以根据不同植物对水的需求来进行分类分量灌溉的自动控制装置,以S7-200PLC为控制器,采用水位节点控制和时钟控制以及湿度传感器,实现对水生植物及土壤植物的智能化灌溉。Water scarcity is one of the major problems facing the world today.The importance of water-efficient agriculture is underscored by the high water consumption in agricultural production.So the automation of greenhouse irrigation becomes a research area.In this paper,an automatic control device was designed which could be used for irrigation according to the water demand of different plants.This design takes S7-200 PLC as controller,uses water level node control and clock control,as well as humidity sensor,realizes the intelligent irrigation to aquatic plant and soil plant.
