Problems solved by technology

When calculating the satellite multi-level system health, this method sets the reconfigurability artificially to 0 and 1, which weakens the physical meaning of various system structures, and only studies the system with one reconfigurability. The method itself has certain limitations

Abstract

A task- and risk-oriented health evaluation method for satellite typical functional structure levels, the method comprising: determining each task that the satellite needs to perform; determining the functional structure block diagram of the satellite level when the satellite performs each task, and the satellite level The functional structure diagram includes multiple subsystems; the satellite-level functional structure diagram of each mission is used to evaluate the satellite-level mission health and risk health of each mission; the satellite-level Weighting and cumulative processing of mission health to obtain satellite mission health, and weighting and cumulative processing of satellite-level risk health of each task to obtain satellite risk health; according to the satellite mission health and the satellite Risk health, which comprehensively evaluates the health status of the satellite.

Description

technical field [0001] The invention relates to the field of satellites, in particular to a task- and risk-oriented method for assessing the health of typical functional structure levels of satellites. Background technique [0002] Satellites have the characteristics of long on-orbit operation time, arduous tasks, and unknown working environment. At the same time, with the increase in the number of satellites and the upgrading of satellite systems in recent years, the structure and functions of the stars have become increasingly complex and diverse, and the integration degree is high, resulting in complex failure modes. Changeable, the failure rate of single machine, system and other components also increases. Therefore, the existing satellite monitoring system has been unable to meet the mission realization requirements of the current high reliability of satellites. At the same time, the traditional satellite state monitoring and health degree calculation focus on the task...
