The information-enhanced fault diagnosis system design of avionics power supply module

This paper is based on the engineering requirements of intelligent fault diagnosis technology, and designes the information-enhanced fault diagnosis system for avionics power supply module. Firstly, we designed the framework of the system, gave the information that needed for fault diagnosis and the way to get it. Then, the fuzzy neural network model was established which combines the neural network model with the fuzzy diagnostic model. Based on this, we designed the fault diagnosis hardware platform with detection chip and data acquisition function, and the software to control it. This paper provides a strong support for the research of avionics embedded intelligent diagnosis method. This paper is helpful for designing the embedded diagnostic reasoning of prognostic and health management system.
