Design And Implementation Of DF File Verification Platform For Cockpit Display System

With the integrated avionics system improvement in the level, the aircraft cockpit display system (CDS)based on ARINC661become more complex, and its safety certification should be harder, existing authentication technologies, including verification tools and verification methods, gradually unable the complexity of the design to meet the requirements. Definition File in ARINC661specification agreed to a graphical interface to the cockpit reality system and user application (UA), verifying the correctness of DF file become an indispensable part of the aircraft cockpit display system reliability. Therefore, the development of Definition File verification platform based on ARINC661is very important, this paper focused on the actual demand, study and discuss DF file verification platform based on ARINC661, expounds the platform architecture and implementation details.Firstly, this paper introduced research background of the topic, and summarized the development of aircraft cockpit display system, ARINC661specification and airborne software testing, gives the research content and the paper structure.Secondly, studied the airborne software validation and ARINC661specification, analysis Definition File structure and formats, and the difficulty of verification, from the Angle of software implementation, summed the requirements of Definition File verification platform.Then, according to the requirements of Definition File verification platform, design the platform from the functional architecture, technical architecture and GUI aspects, and focuses on the three key technologies.Finally, this paper expounds the software development environment, expounds the implementation of main functions in details, brief expounds the testing of the platform. From a real scene experience throughout the authentication platform, shows that the platform is feasible.
