摘要
为了实现对温室大棚环境数据的有效监控,设计了基于无线传感网络的智能监控系统。系统的无线传感网络采用层次结构的路由协议,针对LEACH分簇算法和PEGASIS链路算法进行了融合和改进,提出了一种适用于温室大棚的链簇式路由协议。无线传感节点的设计采用了无线收发芯片nRF24L01+和微控制器STM32,汇聚节点可通过GPRS模块将环境数据上传到远端上位机PC,从而实现数据的远程监控、存储和图表分析显示等功能。
In order to achieve effective monitoring greenhouse environmental data on real time,the intelligent monitoring system based on wireless sensor networks is designed.The system uses a wireless sensor network with hierarchy structure and routing protocol,on top of improved algorithm based on integration of LEACH cluster and PEGASIS chain,one chain/cluster routing protocol which is suitable for monitoring of greenhouses is proposed.Wireless transceiver chip nRF24L01 ＋ and microcontroller STM32 are selected to design wireless sensor nodes,and aggregation nodes can upload the environmental data to a remote host computer PC via GPRS module,which enables remote data monitoring,storage and chart analysis and other functions.
