无线传感器网络在农业温室测控系统中的应用
发布时间：2025-01-15 10:49
无线传感器网络(WSN)将传感器、计算和通信与微型设备结合起来。在现代农业中,无线传感器网络(WSN)为植物的环境监测和控制提供了一种简单而经济的解决方案。监测的重要参数包括湿度和温度。本文提出一种使用了 ZigBee技术的智能低成本无线传感器网络。随着无线传感器网络(WSN)的发展,一种新型的不需要现场布线的温室无线监控系统,己成为农业温室领域的新需求。在所提出的背景下,基于近场通信技术ZigBee和长距离无线通信技术,本文提出并设计了一种新的温室监测系统WSN模型。它具有数据传输可靠,维护方便,成本低的特点。首先,我们在每个温室建立了一个Zigbee无线传感器网络,它有一个中心节点和多个采集节点。然后每个中心节点连接到GSM/GPRS模块。然后,在这些中心节点上,通过GSM/GPRS模块,在温室管理员的移动电话和PC机之间建立了 一个远程无线通信网络。系统测试结果表明,以Zigbee和GPRS为核心的无线传感器网络系统,结合温室监测系统的数据库管理程序,是有效、可靠和可行的。这为温室监测系统的发展开辟了一个新的阶段。
