【摘要】 为了改进边缘网关与云服务器间数据传输效率，文章提出一种基于MQTT协议的数据传输方法与装置。通过边缘网关设置不同的通讯主题，以异步的方式发送心跳包实现与云服务器的连接，优化数据上下传策略，从而降低连接频次。当云服务器有数据需下发时，边缘网关以预定通讯主题优先查收。如云服务器无待下发数据，边缘网关则定期上传心跳包。在心跳包中，打包了边缘网关设备概况简报。若有数据待传，边缘网关暂停上传，先下载并对比新数据与待上传信息。此方法有效减少了网络流量，降低了边缘网关对稳定网络连接的依赖，提升了数据传输的效率和资源利用率。这项研究对于边缘计算和云计算的融合，以及降低网络成本具有实际意义，为未来边缘网关与云服务器间的高效数据交互提供了新的技术方案。更多还原

【Abstract】 This study addresses the issue of data transmission efficiency between edge gateways and cloud servers, proposing an innovative data transmission method and device based on MQTT.By sending heartbeat packets through the edge gateway to establish a connection with the cloud server, the strategy optimizes data upload and download, reducing connection frequency.When the cloud server has data to distribute, the edge gateway prioritizes downloading while embedding data transmission requests within the heartbeat packets.In the absence of pending data from the cloud server, the edge gateway uploads information; however, if data transmission is required, the gateway temporarily halts uploading to first download and compare new data against the information awaiting upload.During periods of no data exchange, the edge gateway uses heartbeat packets to signal and terminate the connection, conserving network resources further.This method significantly curbs network traffic, diminishes the edge gateway’s reliance on stable network connections, and enhances data transmission efficiency alongside resource utilization.The research holds practical significance for the integration of edge computing and cloud computing, as well as for reducing network costs.It offers a novel technical solution for efficient data interaction between future edge gateways and cloud servers.更多还原
