Design of Information System Management Equipment for Spacecraft Based on System Fault Reconstruction Method

Based on system fault reconstruction method, the health detection and diagnosis of information system management equipment is realized by the other equipment of the system. The architecture and software system for information system management equipment and replacement equipment is designed. This method can improve the reliability of spacecraft and save the funds without any increase in cost of additional hardware resources. The re-configurable information system has been applied to the in-orbit flight of manned spacecraft, which can meet the real-time, high reliability and other task requirements, besides providing a reliable guarantee for subsequent fault handling or in-orbit maintenance by astronauts.
