Spacecraft autonomous health management architecture based on comprehensive electronic platform

Abstract

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.

Description

technical field [0001] The invention relates to a spacecraft autonomous health management system structure, and belongs to the technical field of satellite autonomous health management. Background technique [0002] Autonomous health management of spacecraft refers to the ability to operate independently, safely and reliably without relying on ground support. The degree of autonomy reflects the degree of dependence of spacecraft health management on the ground and operators. Autonomous health management technology can provide spacecraft with three capabilities: one is to reduce the amount of ground intervention and measurement and control tasks of the ground system, and independently complete various tasks of normal operation in orbit; the other is to rely on spacecraft failure prediction models or reliability models Predict the working status and development trend of system components to avoid failures; the third is to perform fault diagnosis when a fault occurs to determi...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the newly developed foreign spacecraft have the ability of independent health management, while the independent health management of domestic spacecraft is still in the experimental stage to a large extent, and the advantages of independent health management technology have not been fully utilized, especially the lack of system-level architecture design , the correlation information between subsystems (stand-alone) has not been fully utilized
