Problems solved by technology

For satellites, due to the particularity of the mission, it is often difficult for their historical data to show obvious decline characteristics to characterize the degradation of the health status, but the stability and consistency of the satellite's historical data can reflect the satellite's current parameter deviation and health status. At present, there is little work on satellites in terms of stability and consistency, and the evaluation of satellite stand-alone health status based on data stability and consistency has great application prospects

Embodiment Construction

[0045] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0046] Considering that the health status of a satellite stand-alone product is related to its own characteristics, but the mechanism is complex, the stability and consistency of the satellite can be compared with the historical status, therefore, the inventor of this case uses the template constructed in the health stage to compare deviations to represent The health status of the satellite.

[0047] Considering that the state of the satellite is the most stable after a period ...

Abstract

The invention discloses a satellite health state evaluation method based on data stability consistency. The method comprises the steps of algorithm basic configuration and data calling, stability consistency evaluation and user customized weight adjustment, and finally health state evaluation of an on-orbit satellite single-machine product is achieved. In addition, the invention also discloses a satellite health state evaluation system based on data stability consistency. The method is characterized in that quantitative health state evaluation of the on-orbit satellite single machine is completed, the stability and consistency detection evaluation method and result are fully utilized, dependence of satellite single machine products on expert knowledge can be eliminated or reduced, and customized stability weight and consistency weight adjustment can be carried out according to users.

Description

technical field [0001] The present invention relates to the health state assessment of a satellite stand-alone product, in particular to a method and system for evaluating the health state of a satellite stand-alone product based on data stability and consistency. Background technique [0002] The satellite system is composed of many components and has a complex structure. Coupled with the influence of uncertain factors that may exist in the orbital environment, it is difficult to guarantee that there will be no failures during orbital operation. There are various forms of satellite system faults, and the functions of each component in the system are related. The fault propagation may cause a chain reaction. If it cannot be intervened in time, it will lead to serious consequences. Therefore, there is an urgent need for effective health management of satellites. Due to the variety of satellite failure modes and the lack of failure samples, a systematic and complete satellite ...
