摘要
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。
For the needs of remote monitoring of agricultural environment, we designed a remote greenhouse monitoring system based on ZigBee protocol and CDMA communication technologies. The system used CC2520 which supports the ZigBee protocol to build sensor nodes and sink nodes, and used CDMA wireless communication module to build the gateway for internet connection. Sensor nodes transmit the data to the sink nodes after they composed wireless sensor networks by star topology, then the sink nodes sent the data to the gateway, finally the gateway transmit the data to the remote monitoring center via internet. The monitoring system has the advantages of efficiency energy consumption, flexibility network, as well as easy installation and maintenance, so it is very suitable for remote wireless real-time monitoring of large-scale greenhouse.
