摘　　要：针对气流纺纱机监控终端的软件升级问题,提出了一种基于Wi-Fi网络和MQTT协议的OTA升级设计方案。由升级中心将监控终端应用程序按照规定的标准分包,通过MQTT代理服务器发送到监测终端,终端通过Wi-Fi无线网络获取并解析数据,并通过分包传输、断点续传、应答校验等机制保证了OTA升级的可靠性。该设计为远程升级提供了一个有效的解决途径。Aiming at the problem of software upgrade of monitoring terminal for Rotor Spinning machine,a method of OTA upgrade based on Wi-Fi network and MQTT protocol is proposed in this paper.The upgrade platform allows application program to be sent to the monitoring terminal by MQTT server according to the designed standards.The terminal obtains and analyses the data via Wi-Fi wireless network.The design ensures the reliability of OTA upgrade through mechanisms of subcontract transmission,break point continuation,response verification and also provides an effective solution for the software remote upgrade.
