基于ZigBee和CDMA的温室远程测控系统的设计
China New Telecommunications(2010)
Abstract
针对农业数据远程测控的实际需求,本文进行了基于ZigBee协议和CDMA通信技术的温室远程测控系统的设计开发。以支持ZigBee协议的芯片CC2520来构建传感器节点和汇聚节点,以CDMA无线通信模块构建能与INTERNET进行数据连接的网关。传感器节点采用星型拓扑结构组成无线传感器网络后,采集数据并将测量数据发送给汇聚节点,再由汇聚节点发送到网关,最后网关将数据通过互联网远程传输至测控中心。该测控系统能耗少,组网灵活,安装维护便捷,适合大规模温室的远程无线实时测控。
