Abstract

It is require to design the next generation avionics system while considering applicability under open architecture where standerd communication module is used. In this situation, if the existing schemes cannot guarantee new requirement, new system development is demanded. In this paper, we present design, implementation, and testing procedure for message based middleware to support operational flight program on avionics. System architecture include mission computer (MC) and large area display (LAD) over standard socket communication based on reliable Ethernet. Finally, experimental results demonstrate that the proposed middleware can guarantee real-time with 20msec as well as reliability requirements with no lost packet.

차세대 항공전자 시스템은 표준화 모듈의 데이터통신에 기반한 개방형 아키텍처와 범용성을 위한 새로운 시스템 개발이 요구된다. 본 논문에서는 차세대 항공전자 비행운영 프로그램을 지원하기 위한 메시지 기반 미들웨어를 설계하고 이에 대한 구현 및 테스트를 통한 적용성을 검증한다. 시스템 구성은 임무컴퓨터 (Mission Computer, MC)와 대화면 시현기 (Large Area Display, LAD)를 포함하며 고신뢰의 이더넷기반의 소켓통신이 사용하였다. 마지막으로 실험결과 제안된 방법은 모든 패킷이 20msec의 데드라인에 패킷 손실이 전혀 없이 전달됨으로써 실시간성과 신뢰성 요구사항을 만족시키는 것으로 판명되었다.
