Abstract:

The purpose of the report is to propose a multi-dimensional configurable method of autonomous health management system for spacecraft, which solves the problems of large differences in requirements among different spacecraft and low development efficiency. Through in-depth analysis of spacecraft autonomous health management requirements and on-orbit use in deep space and other fields, more than 10 functions and algorithms are extracted to form universal components. The reuse rate of software code is over 90%, and the development efficiency is effectively increased by three times. The design of the system is described and an example will be shown. Through the design of tabular input of parameters and multi-source fitting of criteria, the construction of health management rule base is realized; the design of data validity service, the quality control of spacecraft health status judgment data source is completed; the undifferentiated anomaly detection module, anomaly isolation and recovery module ensures the spacecraft abnormal state. The real-time disposal ensures the safe operation of the spacecraft. The design can support different spacecraft. It has been proven to be effective in test application, and has popularization value.
