Research On Automatic Configuration Method Of Configuration Control System For Complex Avionics Logic

As an important part of civil aviation aircraft, the avionics system's integration degree is getting higher and higher with the development of the system, and the frequent information exchange between the systems which makes the avionics system information logic hard to control, especially the application of new aviation bus in the plane, the complexity of information logic between avionics system getting increased. Therefore, it is a great significance to have a research on the logical configuration control of the avionics system.The avionics system information logic of Airbus A380 aircraft is regarded as the research object, based on the study of avionics buses such as ARINC429 and AFDX, a visual configuration control system for complex avionics logic which having the function of automatic configuration was built by using the XML modeling and Visio graphical development technology.Firstly, the logic structure of avionic system was analyzed, and the function composition of the control system of complex avionics logic configuration was proposed based on studying on the customers' demand and aviation bus, then the logic configuration model of avionics system was presented and modeled by XML, which laying the foundation for the development of the configuration control system.Secondly, the overall framework of the configuration control system of complex avionics logic was presented, the structure model of the software hierarchy was established,and the relationship between the models was analyzed. Based on Visio 2007 graphical development technology and according to the software structure model, the detailed design of complex avionics configuration's control system logic was completed which including Visio graphical interface, graphical user interface, graphical interface, user interface layer module and configuration information automatic generation module, the logic diagram generation and display module and other function modules.Finally, the automatic configuration of complex avionics logic's control system was tested. The test results show that the designed software can complete the desired function and meet the desired design requirements.
