【摘要】：为实现小粒种咖啡种植园的精量灌溉,达到节水增收的目的,基于无线传感器网络(WSNs)设计了一种滴灌自动控制系统,主要由传感器节点、簇头、控制节点和汇聚节点组成。测试了节点间的有效通信距离为50m,并在此基础上,采用静态簇和节点定位布置的方法进行了灌区划分和节点部署,每个灌区为边长50m的正方形,内设1个簇头、1个控制节点和4个传感器节点。采用定时通信与时间同步技术、休眠技术相结合的方法实现节点数据的无线传输,融合土壤含水率、光强和空气温湿度等信息,采用分区轮灌策略实现滴灌的自动控制。实验结果表明:系统实现了预期设计目标,能应用于小粒咖啡园的精量灌溉管理。
[Abstract]:In order to realize the precision irrigation of small seed coffee plantation and achieve the purpose of saving water and increasing income, an automatic drip irrigation control system based on wireless sensor network (WSNs) was designed, which consists of sensor node, cluster head, control node and convergent node. The effective communication distance between nodes is 50 m. On the basis of this, the method of static cluster and node location is used to divide the irrigation area and deploy the nodes. Each irrigation area is a square with a side length of 50 m and a cluster head inside. One control node and four sensor nodes. The technology of timing communication and time synchronization is used to realize the wireless transmission of node data, the information of soil moisture content, light intensity and air temperature and humidity is fused, and the automatic control of drip irrigation is realized by the strategy of partition rotation irrigation. The experimental results show that the system has achieved the expected design goal and can be applied to the precision irrigation management of small-grain khakephalic orchards.
