基于Zig Bee网络的温室节水灌溉系统设计

为了实施有效的温室节水控制,设计了一种基于Zig Bee网络的温室节水灌溉系统。硬件部分以CC2430构建无线土壤水分传感器网络,包括无线传感器节点、控制节点、协调器节点;软件部分包括底层节点数据的采集和传送、协调器节点数据接收和发送、监控终端管理3个部分。采用LabVIEW对上位机监控软件进行了开发,人机交互界面友好。该系统实现了土壤含水量的自动采集,并根据作物的需水状况进行自动灌溉。实验结果表明:该系统具低功耗、低成本、可靠性好、安装维护方便等特点,通过合理设置控制参数,可以实现节水的目的。

Design on water-saving irrigation system of greenhouse based on Zig Bee networks

In order to implement effective water-saving control,a water-saving irrigation system for greenhouse is designed based on Zig Bee networks.The hardware system is built using CC2430 to construct wireless soil moisture sensor networks,which are composed of wireless sensor nodes,control nodes,coordinator nodes.The software part includes data collection and transmission of rooter node,data receiving and transmission of coordinator node,monitoring terminal administration.The monitoring software running on upper machine is developed by LabVIEW language that provides a friendly human-machine interactive interface.The system realizes automatic collection of soil moisture and automatic irrigation according to water requirement of crop.The experimental results show that the system has many advantages,such as low power consumption,low cost,good reliability,easy for installation and maintenance,etc.Water-saving can be achieved if control parameters are set reasonably.
