面向精准灌溉的传感器网络的研究

Research on sensor networks for precision irrigation

结合我国现阶段国情,分析了田间尺度下精准灌溉的研究价值和实际意义。给出了面向精准灌溉的智能监控系统的总体构架,以及传感器网络系统级和节点级的设计方案;运用RFID相关技术(包括标签、读写器、管理软件)设计了智能支架,从而便于传感器网络节点部署、网络拓扑动态调整和网络管理以适应不同作物和作物不同生长阶段。初步试验表明,本系统的合理性与实用性。

Combining with the situation of China on the stage,the research value and the application significance of precision irrigation,from the perspective of fieldscale,are analyzed.The general framework of wireless sensor networks(WSNs) aiming at precision irrigation,along with the design scheme of WSNs system and node is presented.The intelligent brackets adaptable for different crops and different growth phases,which are convenient for the nodes deploying,the topology adjusting,and the network managing,are designed based on the RFID technique,including of the tag,the reader/writer,and the management software.Preliminary experimentations indicate the rationality and practicability of this system.
