摘　　要：针对在轨模块更换中在轨升级时可更换模块接口受限的问题,分析了在轨升级时模块更替对接口通用性的需求,基于卫星综合电子系统提出了一种新的融合总线的通用接口的设计并搭建了验证平台。该融合总线通用接口融合了4种常用通信总线,能够同时挂接4种通信协议的模块,适应成熟的可更换模块的通信接口,对我国卫星在轨模块更替以提高在轨升级卫星功能有重要意义。Aiming at the limitation of the replaceable module interfaces during the on-orbit upgrade of on-board module replacement, the requirements for the universality of interfaces to support module replacement during the on-board upgrade are analyzed. Based on the satellite avionics system, the design of a new universal interface supporting multi-bus fusion is proposed, and a verification platform is built. The universal interface merges four common communication buses, and can simultaneously connect four modules with different communication protocols in order to adapt to the communication interfaces of the mature replaceable modules. It is of great significance to support Chinese satellites on-board module replacement with the function of on-orbit upgrade.
