Embodiment Construction

[0020] specific implementation plan

[0021] The design and realization of a kind of spacecraft self-guaranteed fault location platform provided by the present invention and its realization are described in detail below:

[0022] 1. Parameter interpretation and fault location configuration

[0023] On the basis of the existing FMECA form, in order to provide users with knowledge input conveniently and intuitively, and considering multiple working conditions and multiple threshold judgment conditions, the present invention uses the FMECA form of each system as the original template to expand. The configuration template file includes failure mode, failure phenomenon (measuring point / telemetry parameter information), fault location system, subsystem, sub-system, component classification, fault propagation impact, and fault threshold parameters. At the same time, the table contains process, instruction, and timing information constraints, which are used to distinguish the paramet...

Abstract

The invention discloses a high-real-time spacecraft autonomous guarantee fault positioning platform, which solves the bottleneck of fault mode knowledge acquisition, realizes high-timeliness fault positioning of a large-scale complex system, and serves as a core function to develop a real-time fault positioning platform capable of being applied to engineering. Knowledge of spacecraft fault modes is accumulated in combination with spacecraft design requirements and designer habits; on the basis of early-stage fault mode analysis, development of a standardized fault mode knowledge acquisition and entry template and a real-time fault positioning algorithm module matched with a data acquisition period is completed. Therefore, a practical high-real-time fault positioning platform which meets the international standard and has a modularized open architecture is developed.

Description

technical field [0001] The invention relates to a high-real-time spacecraft self-guaranteed fault location platform, in particular to a development technology for a fault mode and signal relationship configuration platform and a triple-based fault location technology under high real-time conditions. Background technique [0002] The spacecraft works for a long time, and the subsystems work in coordination and are coupled with each other. This poses an important challenge to ensure the stable operation of the spacecraft under different working conditions. Accurate and effective spacecraft parameter anomaly detection and fault location are very important for spacecraft maintenance. played an important role in safety and security. However, due to the complex structure of the spacecraft, the various cross-linking relationships, and the constraints of instructions, working conditions and its own state, the rules of anomaly detection and fault location of the spacecraft are comple...
