摘要
为了实现温室大棚环境的无线、远程实时监控,提出了一种以CC2430芯片为核心的ZigBee温室环境无线测控系统;描述了终端节点、路由节点和协调器节点的硬件组成和软件流程,并应用改进的Cluster-Tree路由算法组成ZigBee无线传感网络,实现数据的无线传输;利用串口通信技术实现无线传感网络与Yeelink物联网平台的通信,管理者可远程登陆Yeelink平台和手机APP查看温室环境信息以及控制节点状态;经实验测试,大棚内无线节点间的通信距离约80米,并且实现了光强、空气温湿度及土壤湿度的监控;测试表明系统构建简单,稳定可靠,为智能农业的设计提供了参考。
In order to realize wirelessly and remotely real--time monitoring of the greenhouse, this paper presents a monitoring and con- trolling system based on ZigBee wireless sensor network with CC2430 chip. Design in hardware and software flow for the terminal node, rou- ting node and coordinator node are presented, and the improved Cluster--Tree routing algorithm is used to form the ZigBee WSN for data wireless transmission. Communication between WSN and Yeelink IoT platform is realized by serial communication technology, managers can log on Yeelink platform or APP in phone to remotely view the greenhouse environment information and control node status. By testing, the communication distance between the wireless nodes in the greenhouse is about 80 meters, and the monitoring of light intensity, air tempera- ture and humidity and soil moisture is realized. The simulation experiment certifies that the system is simple, stable and reliable, and it provides reference for the design of intelligent agriculture.
