摘要
为了实现精准灌溉和节约用水的理念,提出了基于嵌入式Linux内核移植设备驱动的温室微喷自动装置。通过分析温室参数和作物生产信息,利用传感器网络采集温室内温、湿度等环境因子,采用微喷灌调节和控制温室内环境,为农作物生长提供最有利的条件。文中重点研究了嵌入式内核系统、传感检测网络、数据处理单元及水泵送水管道组件的微喷自动控制装置,并搭建了试验平台。试验表明:该系统能实现对温室环境实施实时监测,可通过电磁阀控制执行器进行微喷灌水,有效控制环境因子,可靠性强、稳定性高,对微喷灌溉应用于农业种植具有重要指导意义。
In order to meet the concept of precision irrigation and water saving , it puts forward an automatic device based on embedded Linux kernel for greenhouse micro injection .Through the analysis of the greenhouse and field parameters and crop production information , the system makes use of the sensor network to gather the greenhouse temperature and humidity environment factor , micro irrigation regulation and control in greenhouse environment and crop growth to provide the most favorable conditions .In this paper , we focus on the embedded kernel system , sensor detection network , data processing unit and the micro injection automatic control device of water pump , and set up the experimental platform . Experiments show that the system can meet the real-time monitoring of greenhouse environment , and by controlling the e-lectromagnetic valve actuator of micro spray irrigation , effective control of environmental factors , system not only has high reliability , high stability , micro spray irrigation application in agricultural cultivation , which has an important guiding significance .
