摘　　要：为解决可重构卫星在轨组装过程中信息系统重构的问题,提出一种可重构卫星信息网络系统,基于SpaceWire总线构架,设计可重构信息网络系统的路由器及基于Dijkstra算法的计算机节点寻径算法。当信息网络系统拓扑构架变化后,计算机系统可根据新构架下各路由器反馈的链路信息配置各路由器的逻辑地址,实时更新各路由器的路由表内容,解决不同功能模块之间互相感知、动态互联的问题。该系统能够满足可重构卫星在轨模块组装与重构时,功能模块之间对接、扩展以及信息网络实时动态构建等要求。To solve the problem of in-orbit information network system reconfiguration of reconfigurable satellite,a reconfigurable satellite information network system based on SpaceWire bus architecture was presented.Routers for reconfigurable information network system and Dijkstra algorithm based routing algorithm were designed to achieve real-time update of routers’logical addresses and lists of neighbor router according to feedbacks from other routers in transformed system structure after topolo-gical transformation of information network system.Dynamic connection and mutual perception between random functional mo-dules were realized.This information network system can meet the requirements of free connection and expansion between functional modules and real-time dynamic construction of information network.
