Abstract:As the core sub-system of integrated avionics system, display control management sub-system is the man-machine interface by integrated display and central control. Due to the actual problem of equipment shortage difficult to satisfy the teaching need, functional requirement of display control simulation experiment system is expounded, overall structure based on TCP communication is constructed, integration plan of display control simulation equipment is analyzed to construct the visual Semi-physical operation environment. Software design of overall structure, main control, interface management, picture display and management, communication, equipment function simulation and development of experiment item is analyzed, to establish the base for further implement software code, and to provide practicable technology way for the development of avionics simulation training system of other plane.
