基于 ZigBee 和 LabVIEW 的土壤温湿度监测系统设计

摘要

针对目前土壤温湿度监测系统中存在的有线网络及人工抽样监测方式存在的成本高、灵活性差的问题，设计了一种基于无线传感器网络Zigbee 和 LabVIEW 的土壤温湿度监测系统。系统的传感器终端节点、路由节点、协调器节点都以 CC2530为核心，终端节点采集温湿度后，将数据无线发送到路由节点，然后再转发到协调器节点，协调器节点将数据处理后传递到上位机进行监测。上位机界面采用 LabVIEW 软件开发，可实现实时数据显示、历史数据回读和报警设置及实现等功能。实验结果表明，该系统采集数据较准确、成本低，解决了现有土壤温湿度监测系统存在的问题。%Aimed at the present problems about the soil temperature and humidity monitoring system, such as the cost of cable network and artificial sampling monitoring is high and flexibility, this paper introduces a design of soil temperature and humidity monitoring system based on wireless sensor network Zigbee and LabVIEW.CC2530 is the core of the sensor terminal node, routing node and the coordinator node.The terminal node collects temperature and humidity, the data is transmitted wirelessly to the routing node, and then transmitted to the coordinator.The coordinator node processes the da-ta and transmits to the PC monitor.PC interface is exploited with LabVIEW, which can realize real-time data display, historical data read back, alarm setting and implementation and other functions.The experimental results show that, the system has advantages of accurate data acquisition, low cost, solving the existing problems in soil temperature and humid-ity monitoring system.
