Research On Display Function Model Of Airborne System In Flight

The airborne system is an important carrier for the realization of various functions of the aircraft.In the context of the development of the flight simulation function of the A320 distributed virtual maintenance simulator,there are many types of airborne systems for the A320 aircraft,which causes excessive modeling workload in the simulation process.To study the problem,put forward and establish a general functional model of the system with the display function as the core,and finally implement the software through the virtual machine platform.The specific research process of the paper is as follows:Firstly,the research background and significance of the paper are explained,and the virtual maintenance technology and airborne system simulation at home and abroad are studied and analyzed,and the research perspective of this paper is proposed;Secondly,from the perspective of the display function of the system,the system is functionally analyzed,and the system is divided into four parts: the input module,the logic module,the calculation module and the output module,and the GTST-MLD method is used to structurally analyze and describe the system display function.The main function tree and supporting function tree of the system are described by the correlation matrix between the two,and a general model of the display function of the airborne system is established;Taking the cabin pressurization system and the air-conditioning system as examples again,the structural composition,working mode and typical faults of the system are briefly described.From the perspective of the system’s operating characteristics and display information acquisition,the display function implementation is analyzed,and all The required functional modules have completed the construction of the display function model of the cabin pressurization system and air-conditioning system according to the steps of establishing a general model;Finally,the functional model of the cabin pressurization system is implemented on the A320 distributed virtual maintenance simulator platform.
