摘要

The research of Aircraft Maintenance System based on flight data is an important direction of development at the present time. By studying the characteristics of avionics bus signals, this paper develops the modeling work of two major signalsȁ4;ARINC429 and RS422 bus signals, explores the method of data simulation and designs application software to implement configuration of signals and simulation of flight data. The research work of paper provides aircraft health maintenance system and fault diagnosis with a data source and effective technical means for further study of fault diagnosis and trend prediction by using the flight data. In engineering practice, the methods of modeling and simulation proposed in the thesis has been verified. The experiment shows that the system runs stably and credibly and data simulation of the signal is accurate and capable to meet the real-time request.
