基于无线传感器网络的农田环境监测系统设计

Design of Farmland Environment Monitoring System Based on Wireless Sensor Network

实时、准确获取农田环境信息是实现农业精准化作业、智能化管理的基础,也是农业信息化建设中的一个重要环节.设计了一种基于无线传感器网络的农田环境信息监测系统,通过分布于田间的传感器节点采集作物生长环境参数,采用CC2530构建Zig Bee数据传输网络,利用嵌入式网关完成Zig Bee网络、Wi Fi网络和GPRS网络的信息交互,实现了农田环境信息的远程监测.测试结果表明,该系统组网方式灵活、数据监测准确、覆盖范围广,通信距离可达350 m左右,为农田环境远程监测提供了一种有效可行的解决方案.

Real time and accurate acquisition of farmland environmental information is the basis of precision operationand intelligent management of agriculture,and it is also an important part of agricultural information construction. Afarmland environment information monitoring system based on wireless sensor network is designed,crop growthenvironment parameters are collected by sensor nodes distributed in the field,using CC2530 to build Zig Bee datatransmission network,the information transmission between Zig Bee network,Wi Fi network and GPRS network isrealized by embedded gateway,and the remote monitoring of farmland environmental information is realized. The testresults show that the system is flexible,the data is accurate,the coverage is wide,and the communication distance isup to 350 m,which provides an effective and feasible solution for remote monitoring of farmland environment.
