Embodiment Construction
[0042] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0043] There are various formats and types of flight parameters, and some continuous parameters are difficult to reflect through logic rules, such as vibration signals, temperature signals, pressure signals, etc., but these parameters are crucial to accurate fault location. Since these parameters can be represented by numerical expressions, and neural networks are based on numerical calculations, neural networks can be used to solve this problem.
[0044] In addition to some flight parameters suitable for neural network processing, there are a large number of flight parameters suitable for fuzzy rules, such as fault word information, flight altitude, remaining fuel, etc. In addition, information such as fault symptoms and preliminary fault detection results in fault messages are also suitable for the representation of ...
