Arinc429 Data Research And Realization Of Test Analyzer

Aviation bus technology is the base of avionics integrated system, with responsibility for information exchange and resource sharing between different subsystem on the plane. Because of the key status of the aviation bus in avionics integrated system, its reliability and stability become more and more important. So aviation bus test system is generated based on this background.The ARINC429 Data Bus Test and Analysis System is designed for the requirement above. The project comes from Shanghai Aircraft Design And Research Institute. The system will be widely used on the advanced plane ARJ21 in 21st century. It will apply for the simulation, interface, analysis and research of communication data in the stages of design, experiment and maintenance in outfield.Based on the research of the ARINC429 bus and bus test technology, the ARINC429 Data Bus Test and Analysis System is developed. This thesis starts with an introduction, which explains the development of the aviation bus. Afterwards, aviation mechanism and bus test technology are studied, and the ARINC429 protocol is analyzed. Then, the functions of the system is generally depicted, the data structure of interface between ICDB and ARINC429 Data Bus Test and Analysis System is defined, and a kind of efficient bus data description method is put forward. Furthermore, the design scheme of the system is expatiated. Finally, the functions of the system are successfully verified.Through the research of this thesis, we not only realize the aim of the system by the combination of ARINC429 bus and bus test technology, but also make the technology and methods used in real-time and bus data description have certain utilities in other aspects, and the outcomes are helpful to the research of other aviation bus test systems.
