Multimedia based multi-fault diagnosis of satellite sensor based on gauss Bayesian algorithm

摘要

A fault diagnosis method based on Gauss Bayesian algorithm is proposed to improve the multi-fault diagnosis accuracy of satellite sensors. Firstly, the working principle and common failure modes of satellite sensors are analyzed, and a multi-fault diagnosis model of satellite sensors is constructed; Secondly, the HONBM algorithm is used to analyze the fault diagnosis and anti-mismatch strategy of the satellite sensor system to improve the performance of the algorithm, the fault diagnosis process of satellite sensor system based on Bayes network and the anti-mismatch strategy are given. Finally, the effectiveness of the proposed algorithm in multi-fault diagnosis of satellite sensors is verified by simulation experiments.
