Spacecraft autonomous health management architecture based on comprehensive electronic platform

A spacecraft autonomous health management architecture based on a comprehensive electronic platform divides spacecraft faults into five classes, a different detection method and a different restoration strategy are adopted by each class of faults, and a classified and layered health management architecture is formed. Zero-class faults are guaranteed through self-reliability design of one machine, health management of first-class faults is completed through a platform load integrated service unit health management module, a control integrated service health management module and an FDIR central control task module, a relevant fault health management module completes health management of second-class faults, and a special detection and module control module completes health management of third-class faults and fourth-class faults. The spacecraft autonomous health management architecture is based on the comprehensive electronic platform, has generality, and can meet health management requirements of spacecrafts of different types.
