摘　　要：针对目前卫星系统高中低速接口难以互接、多类型数据源难以拓展,以及各接口协议并存现状难以满足当下各类在轨任务向多层次、高速率、大数据发展需要的问题,设计一种星载多协议交互网络。该网络硬件架构以高速信息交换器为核心,应用串行RapidIO(SRIO)SWITCH芯片与协议转换控制FPGA芯片实现了1553B和SpaceWire等星上总线的互联,在更好地发挥系统可拓展性的同时实现了具有灵活互通的多协议转换传输模式。对文章提出的网络设计进行协议转换与传输速率验证,结果表明:该设计使具有不同速率、不同来源、不同类型特点的数据在星载环境下能够得到更有效、更便捷的部署,具有一定的参考价值。Aiming at the current situation in satellite systems where high,medium and low-speed interfaces are difficult to interconnect,multiple types of data sources are hard to expand,and various protocol interfaces are difficult to coexist,which can not satisfy the needs of on-orbit tasks developing multi-level,high-speed and big data,a spaceborne multi-protocol interaction network is designed.The network architecture,centered on a high-speed information exchanger,uses a SRIO(serial RapidIO)SWITCH chip and a protocol conversion control FPGA chip to achieve interconnection of on-board data buses such as 1553B and SpaceWire,which not only enhances the system expandability but also achieves a flexible multi-protocol conversion transmission mode.The protocol conversion and transmission rate of the network design proposed in this paper are verified,and the results show that the design allows data with different rates,sources and types to be deployed more effectively and conveniently in the spaceborne environment,offering certain reference.
