摘要
针对农田信息采集和监控具有成本高、维护困难和通信繁琐等诸多问题,提出了一种基于3G模块和ZigBee无线通信技术的智能农田监控物联网设计方案.首先,设计了系统的总体构架,将系统分为ZigBee网络、3G模块和远程客户端三个部分;然后,给出了系统硬件设计方案,设计了以CC2430和JN5121作为微控制器和无线通信模块的ZigBee传感器节点、路由器以及协调器;最后,对各节点的软件流程进行了描述和分析.通过远程客户端测试表明该系统可以正确、实时地采集农田信息,并具有灵活性强、成本低的优点.
Aiming at conquering the high cost, maintenance difficulties and communication complication of information collection and monitoring in farmland, an internet of things for intelligent farmland monitoring based on 3G module and ZigBee communication technology is proposed. Firstly, the main structure of the system is designed, and the system can be di- vided to ZigBee network, 3G module and the remote client;and then the micro-controller and the wireless communication module CC2420 and JN5121 are used to design the sensor node, router and the coordinator; finally, the node software flow is described. From the experi- ment, we can find the system can correctly and in-timely collect the agriculture field infor- mation and have the strong flexibility and low cost.
