摘要
由于Zigbee无线网络在智慧农业应用中存在组网结构复杂、传输距离短、信号易干扰、数据传输安全性低等缺点,提出一种基于LoRa技术的低成本远程温室大棚环境监测系统设计方案.该系统总体设计从下到上由传感层、汇聚层和网络层三层架构组成,成功实现温室大棚环境参数的采集、上传和显示.测试结果表明,该方案具有组网简单、通讯距离远、数据传输可靠性高、功耗低、工作周期长等特点,能够满足智慧农业自动化、智能化和集约化的实际需求.
Due to the fact that the Zigbee wireless network has shortcomings such as short transmission distance,complex network structure,vulnerable signal interference and low data transmission security in intelligent agriculture applications,this paper puts forward a design scheme of low cost remote greenhouse environmental monitoring system based on the LoRa technology.The overall design of the system is composed of three layers:the sensing layer,the convergence layer and the network layer.The system successfully realizes collection,upload and display of greenhouse environmental parameters.The test results show that the scheme has the characteristics of simple networking,long communication distance,high data transmission reliability,low power consumption and long work cycle,and can meet the actual needs of automation,intelligence and integration of intelligent agriculture.
