Aircraft Avionics Display And Control Computer Video Display Technology

Technology of display&control application in airbone intergrated avionics system display& control computer is introduced in this paper, which include procedure of research, design and implemention. The computer system is plan to be used in the next-generation' s military plane as a strong support of airbone intergrated display & control system. In come to the develop requirement of avionics system, we have processed pre-research project in small scale intergrated, it will play an important role on aspect of intergrated functions, and promote military plane' s fight power, on the other hand , it decrease work pressure of pilot.At the beginning, the history , currentence and tendency of the avionics system is reviewed. Then , the general architecture of airbone computer system is analyzed , and system architecture of intergrated display & control computer(IDCC) is given .As the core teachnology of IDCC, this article focuses on the design and implemention teachnology of display & control. Firstly, the theory of vectorgraph and raster video is expilicated.The function and configuration of display file is provided . Secondly, the methods of design for each functional part about two display mode is analyzed, which include symbol generation logic, special draw logic schematics, video image module and display interface circuit.At Last, the debudgging software and application programe adopted to IDCC system software are also discussed.IDCC' s prototype has been completed. The result shows that the design of IDCC reaches the expected requirement of display. Now, the technology has been used well in some particular system.
