Abstract
Description
technical field
[0001] The invention relates to an aircraft fault intelligent diagnosis method and system, in particular to a fault diagnosis method and system for flight parameters and fault messages uploaded and downloaded in real time from the aircraft. Background technique
[0002] At present, in the field of aircraft fault intelligent diagnosis, a single diagnostic technology such as expert system or neural network is generally used. This method has some disadvantages, such as the disadvantages of the expert system mainly include poor diagnostic accuracy and difficulty in overcoming the "bottleneck" problem of knowledge acquisition, while the neural network is only a process of data calculation in a sense, and we cannot accurately understand it. What exactly the neural network has learned, due to the lack of expert experience, it is impossible to correctly interpret the calculation results, and the neural network needs to be trained repeatedly for a long time and with a...
