Spacecraft in-orbit fault detection and fault processing system and method

The invention discloses a spacecraft in-orbit fault detection and fault processing system and a method and belongs to the technical field of automation. The system provided by the invention comprisesa spacecraft network interface, a rapid fault data output interface, a key parameter collector, a big data fault information memory, a fault diagnosis knowledge base, a fault logic inference machine,a fault conclusion list, fault processing instruction sheets and a fault processing executor. According to the system and the method, the defect in the prior art is overcome; spacecraft fault information is stored through utilization of the big data fault information memory and spacecraft faults are comprehensively processed, so a great number of software and hardware overheads resulting from spacecraft fault classification processing are overcome; moreover, the spacecraft in-orbit fault diagnosis knowledge base and the fault logic inference machine are established, so in-orbit automatic diagnosis can be carried out, a
