Research And Design Of Cockpit Display Graphical Interface Based On ARINC661

With the increasing task demand and functional requirements of avionics,the traditional cockpit display platform is unable to burden the complex avionics information,and is not conducive to the maintenance and functional expansion of the later stage.The ARINC Specification 661 plays an important role in the realizat ion of open cockpit display system.It isolates the picture display from the picture control and defines the graphical user interface and communication instruction interface respectively.The definit ion file defines the screen information and the widget is regarded as the graphical user interface.The user applicat ion controls the picture logic through the dynamic instruction information and finally realizes the picture driving.In this paper,the graphic display system of cockpit display system will be studied deeply.Firstly,this paper will show the research about the design and logic control of cockpit display system in the ARINC Specification 661.It summarizes the requirements of avionics display information.Then,the definition f ile of static picture design and dynamic image rendering technology will be researched,especially about the modeling and graphical display of widgets.The interactive technology of the coordinates and the graphic technology of widgets are also the focus of th e paper.To realize the personalized design of display screen,the generation technology of special symbol design command is researched and implemented.Next,the paper summarizes the dynamic parameters of the graphic interface and the design of the bottom interface.Finally,it achieves the real-time display of cockpit display system.At the same time,we study the new rendering sequence to improve the display efficiency and performance of display.A large number of test results show that the design method of the graphic design system of CDS in this paper meets the standard of engineering application.It has great universality and practicability.The display effect can meet the desire requirements.The graphic design system of cockpit display system has been applied in several models of aircraft successfully.
