摘要
LoRa是目前窄带物联网领域的研究热点,文章选取开源ChirpStack作为LoRaWan Server,分析了Docker容器技术特点,基于Docker容器技术对ChirpStack组件的安装、配置和部署流程进行验证,对LoRa节点的入网方式和工作模式进行分析。文章选用XC20型LoRa模组和TJ81型LoRa网关进行组网和数据传输,经验证LoRa节点数据经网关透传后成功上行至LoRaWan Server,可通过MQTT协议实现数据上下行,系统运行稳定。研究为后续使用LoRa技术进行物联网应用层接入提供了有力的云平台支撑。
LoRa is a research hotspot in the field of narrow-band Internet of Things.This paper selects open-source ChirpStack as LoRaWAN Server,analyzes the technical characteristics of Docker container,verifies the installation,configuration and deployment process of ChirpStack components based on Docker container technology,and analyzes the network access mode and working mode of LoRa node.This paper selects XC20 type LoRa module and TJ81 type LoRa gateway to carry out networking and data transmission.It is verified that LoRa node data is successfully uplink to LoRaWAN Server after transparent transmission through the gateway.And it realizes data uplink and downlink through MQTT protocol,and the system runs stably.The research provides a strong cloud platform support for the subsequent use of Lora technology for Internet of Things application layer access.
