摘要/Abstract

摘要： 根据农田环境的应用需求,设计了基于无线传感器网络的精准农业控制系统,该系统由无线传感器网络、无线网关和监测中心三部分组成。传感器网络由低功耗无线传感网络节点通过ZigBee自组网方式构成,采用层次型分簇拓扑结构,采取适当的休眠机制降低系统功耗。采用基于ZigBee协议的CC2530芯片设计无线节点,给出了应用系统体系结构、ZigBee传感器节点结构、系统各部件软件设计。试验测试表明节点能够有效地采集数据,并可以在节点间成功地进行通信,采取休眠机制后,系统能耗降低,网络生命周期明显增长。

Abstract: Rapid advancement of the information-based technologies provides opportunities for breakthroughs in agricultural applications as well.The environmental parameters on the farmland can now be monitored in real time through the use of state-of-the-art sensing devices.In turn,the collected data would be the basis for precision controls.The present system was established for agricultural applications based on wireless sensing networks.It employed real-time online monitoring to generate needed environmental data,and consisted of wireless sensors,gateway and control center.The sensing network applied the hierarchical clustering algorithm for its topology,and the sleep-schedule on the sensors for energy-savings.The sensor nodes were designed based on CC2530 chip with the ZigBee protocol.The structures of applied system and ZigBee sensor node,as well as the software,are presented.The trial runs showed that the system was effective in data collection and network communication.In addition,the sleep-schedule not only reduced the energy consumption but also significantly prolonged the hardware's useful lifespan.
