Research of Fault Diagnosis System for Remote Sensing Satellite Receiving System Base on Fault Tree

摘要

The stable operation of the remote sensing satellite receiving system is related to the success or failure of satellite data reception. Accurate fault diagnosis can promptly and effectively troubleshoot and reduce the loss of economic and social benefits. Aiming at the characteristics of fault diagnosis for remote sensing satellite receiving system, a fault diagnosis expert system based on fault tree is designed in this paper. The system builds a fault tree model and expert knowledge base for a remote sensing satellite receiving system, and uses a combination of forward reasoning based on a rule framework and quantitative fault tree analysis to locate the fault. The fault diagnosis expert system has been applied to practical engineering projects, which effectively improves the efficiency of fault diagnosis of remote sensing satellite receiving systems, and is conducive to preventing and controlling faults of remote sensing satellite receiving systems.
