Airplane Fault Detection Based on Segmental Distance and Subsequence Match
Abstract:As about high repetition and large volume of data in airplane fault detection data as well as low efficiency and accuracy of monitoring algorithm,this paper,based on PAA packed data,utilizes segmental probability to extract,adjust FP Growth and establish FP Tree,thereby reducing repetition degree of data and improving its searching speed. In addition,algorithm on the basis of segmental distance and subsequence match is proposed. In this paper,the real QAR data of flight will be adopted to verify reliability and accurateness of the algorithm.
