AI Technical Summary

Technical Problem

Existing spacecraft fault diagnosis methods are implemented through fault expert programming, which binds developers and users, making it impossible to achieve efficient system construction and flexible use. Furthermore, the fault rules based on time-series characteristics are complex or cannot accurately describe the fault judgment logic.

Method used

The spacecraft fault rules based on time-series logic are used to represent telemetry results data. Data preprocessing and syntax verification are performed, and fault rules are calculated through state transition sequences to achieve spacecraft fault diagnosis.

Benefits of technology

It enables spacecraft fault diagnosis without requiring developers to write programs, improving the versatility and speed of the diagnostic method, and supporting cross-target fault judgment and large-scale fault detection for multiple spacecraft.
