The product characteristics and maintenance characteristics of space complex repairable facilities were analyzed to aim at the maintenance requirements with a large number of on-orbit replaceable units, complex systems, and high operation accuracy. An intelligent induced maintenance system for space application facilities was developed, and unique evaluation criteria were established. The system, key technologies, and application effects are verified through typical application cases and comparative experiments. The results show that the implementation of the system can effectively reduce the workload of the astronauts in orbit and improve the work efficiency and provide new cooperation means for the astronauts to solve the urgent and unexpected tasks in orbit.
