基于 GPRS 与无线传感器网络的农田环境监测系统设计

摘要

农田环境信息是现代农业实施精确施肥、灌溉的重要依据。考虑农田覆盖面积大，设计了基于 GPRS 与ZigBee 无线传感器网络的农田环境信息监测系统。该系统包括微型传感器节点、ARM 网关和上位机软件。采用CC 2530芯片设计微型传感器节点采集区域农田环境信息，传感器节点以树形拓扑的 ZigBee 网络向协调器传送数据；ARM 网关集成协调器和GPRS模块，实现了ZigBee 网络与GPRS网络、Internet 信息交互，完成了农田环境信息的远程监测。系统可以在大区域内监测农田环境信息，并可将结果在客户端（包括手机、PC 等）的上位机软件显示，有效地解决了传统监测系统存在的能量、传输距离受限等问题。%The farmland environmental information is an important basis for modern agriculture to the implementation of precise fertilization , irrigation .Considering farmland area covered largely , farmland environmental monitoring system is designed based on GPRS and ZigBee wireless sensor network ( WSN ) .The system includes micro-sensor nodes , ARM gateway and software of PC .Micro-sensor nodes are designed by CC 2530 chip to monitor the farmland environmental in-formation,sent the data collected to the by the ZigBee network of tree topology;ARM gateway integrated coordinator and GPRS to exchange the information between ZigBee networks ,GPRS networks and internet ,to remote monitor the farmland environment information .Farmland environmental information monitoring system can be remote monitoring in a large area of farmland environmental information ,and can display the result in the client ( including mobile phones ,PCs, etc.) and solve effectively the problem of the traditional monitoring system , including high energy consumption , transmission dis-tance limited .
