Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] figure 1 The flow chart of data collection from wireless sensor network to mining of uncertain maximum frequent itemsets provided by the embodiment of the present invention. In practical applications, the data collected by the infinite sensor network has a complex structure, various categories, and there may be problems such as missing data. Therefore, the collected original data cannot be directly used for mining uncertain maximum frequent itemsets, bu...

Abstract

The invention discloses an aircraft flight fault law early warning determination method and device, and relates to the technical field of item set mining. The method is used for solving the problems that existing aircraft faults occur frequently and fault early warning is inaccurate. The method comprises the following steps: sorting a plurality of first frequent item sets included in a frequent item set set according to the number of item sets, and determining a first frequent probability of each first frequent item set; determining a first frequent item set corresponding to the first frequent probability greater than a first probability threshold as a second frequent item set, and determining a second frequent probability of the second frequent item set; determining a second frequent item set corresponding to the second frequent probability greater than a second probability threshold as an uncertain maximum frequent item set; According to the meanings of the items included in each uncertain maximum frequent item set, determining the flight fault law of the aircraft.

Description

technical field [0001] The present invention relates to the technical field of item set mining, and more specifically relates to a method and device for determining aircraft flight failure rules. Background technique [0002] The frequent itemset mining algorithm can mine the aircraft flight fault information with high frequency from the collected aircraft flight data, so as to solve the problem of untimely and inaccurate aircraft fault warning caused by the complex and changing environment of the aircraft flight. However, frequent itemsets are not enough to solve the increasingly complex problem of early warning of flight faults. The reason is that the more frequent itemsets, the less meaning they express, the correlation between itemsets is lost, and the frequent itemsets are incomplete. In the application scenario of aircraft flight failure, there are usually many factors of flight failure and they are related to a certain extent. If you only pay attention to one type of ...
