摘要
LoRa技术具有远距离、低功耗、抗干扰等特点。文章将LoRa运用到温室大棚环境信息采集系统中,实现远程监控及科学管理。系统以LoRa调制技术为核心,采用sx1278芯片,星形拓扑组网,传感器采集现场数据并通过LoRa通信模块将数据汇聚。文章研究了LoRa技术特点,提出了系统的整体架构和软硬件设计方案,实现了基于LoRa的温湿度采集系统并进行了测试,系统运行状态良好,该方案有着广泛的应用前景。
LoRa technology has the characteristics of long distance,low power consumption and strong anti-interference ability.In this paper,LoRa is applied to the greenhouse environment information collection system to realize remote monitoring and scientific management.The system takes LoRa modulation technology of sx1278 as the core and is designed using star networks.Field data is collected by sensors and transmitted by LoRa communication module.The paper analyses basic theory of LoRa,proposes the framework of the whole system,designs hardware and software of nodes,then implements a temperature and humidity acquisition system based on LoRa.The final tests indicate that the system runs well and the scheme has full practicability.
