针对国内缺乏对新型飞机通讯模型研究的状况,本文在研究波音787和空客380通讯模型基础上,按照ARINC624规范,建立了一种中央维护计算功能(CMCF)系统的通讯模型,并经过搭建硬件测试平台和系统数据测试,验证模型符合ARINC规范,这对国内对机载维护系统的研究和对国产大飞机C919的的研究有一定的现实意义。 Aiming at the lack of research on the new aircraft communication model in China, this paper establishes a communication model of CMCF system based on the ARINC624 specification based on the communication model between Boeing 787 and Airbus 380. After establishing the hardware Test platform and system data test, the verification model conforms to the ARINC standard, which is of certain practical significance for the domestic research on the airborne maintenance system and the research on the domestic large aircraft C919.
