摘　　要：随着互联网+低轨卫星的到来,传统卫星由于在轨处理弱、通信机制单一、载荷及应用数据交互复杂等不能满足未来卫星的功能需求,因此,实现数据快速交互共享、数据实时处理、载荷及应用通信服务接口统一等已成为新的挑战。文章提出了基于MQTT通信协议的数据交互系统方案,实现了多个任务应用及各类载荷的通信和消息共享;应用交互功能服务开发简便、灵活,可快速将并发载荷及应用接入平台。该方案提供了统一通信交互接口,不仅可以实现消息的可靠传输,而且降低了应用程序及载荷的耦合程度,易于后续功能的开发、迭代升级、应用部署。With the arrival of Internet +LEO satellite constellation,the traditional on orbit processing is weak,the communication mechanism is single,and the load and application data interaction are complex,which cannot meet the functional requirements of future satellites.Realizing rapid data interaction and sharing,real-time data processing,and unified load and application communication service interfaces has become new challenges.This article proposes a data interaction system scheme based on the MQTT communication protocol,which enables communication and message sharing among multiple task applications and various payloads;The development of application interaction function services is simple and flexible;Quickly connect concurrent workloads and applications to the platform.This solution not only enables reliable transmission of messages,provides a unified communication interface,but also reduces the coupling between application programs and workloads,making it easy for subsequent functional development,iterative upgrades,and application deployment.
