Reconfigurable satellite-borne information network construction method based on special link information node

Abstract

Disclosed is a reconfigurable satellite-borne information network construction method based on a special link information node, a SpaceWire router is used for controlling a module unit, and all moduleunits communicate with one another through the SpaceWire router. Each module unit routes are not divided into master and slave nodes and can be suitable for construction of a satellite-borne information network with variable topology; a certain special port of a SpaceWire routing chip is designated as an internal node and is specially responsible for router information acquisition, so that the complexity of realizing an expansion function based on a Spw routing physical address 0 is avoided. The problems of arbitrary dynamic interconnection among different functional module units, mutual perception among multiple routers, realization based on SpaceWire bus route architecture engineering and the like are solved, and the requirements of assembling and reconstructing a reconfigurable satellite on-orbit module are met. Any functional module units can be freely butted and freely expanded, and an information network can be dynamically constructed in real time.
