面向温室集群的环境无线监控系统设计

Design of Wireless Monitoring System for Greenhouse Cluster Environment

该文提出了一种基于无线传感网的大规模温室环境无线监控系统的设计方案。以CC2530作为节点的中央控制芯片,进行了基于Zig Bee协议栈的传感器节点的设计,组建基于星型与树型相结合的混合路由型无线数据传输网络,最后协调器通过虚拟串口将数据传输至监控中心的主机上,实现了对农作物多生理信息采集、传输以及实时显示、异常报警、远程控制等功能。实验表明,该系统具有部署灵活、易扩展、低能耗等特点,可很好地降低使用成本,对现代化农业具有实际应用价值。

The paper presents the design method of a wireless monitoring system for large-scale greenhouse environ- ment based on wireless sensor network. The system used CC2530 as central control chip to design sensor nodes based on ZigBee protocol stack,and a hybrid wireless data transmission network based on the combination of hybrid Routing star and tree network was developed,finally the wireless network coordinator transmitted environmental infor- mation to the monitoring host through virtual serial port. System achieved the crop physiological information collec- tion,transmission and real-time display,abnormal alarm and remote control,and other functions. The experimental re- suits show that the system features reliable,flexible deployment,easy expansion,low energy consumption,and it saves the cost well,has important application value for modem agriculture.
