Abstract:

Aiming at the short supply of special training equipment and the more and more prominent urgency of maintenance staff training on civil aviation industry is a power simulation system for maintenance mechanics is designed. Based on multiple input multiple output of aircraft power supply system and the characteristics of complex control logic with consideration of the connection between other electrical systems at the same time,the function logic of input,ontology,output is put forward and the simplified unity function model is established. Matrix identification is used to determine the mathematical model,solving the complex logical relationship between various elements,accelerating the system simulation speed and enhancing the subsequent extensibility. The current system can already achieve normal function simulation of power page,emergency panel and control panel as well as many kinds of power systemfault simulation.

Key words: maintenance simulation, system modeling, function model, fault simulation
