飞机座舱显示系统关键技术研究

Research on key technologies of aircraft cockpit display system

随着综合化航空电子技术的发展,舱内的多个显示器已不再是独立的个体,需要根据特定场景及飞行员外部操作进行相互协调、动态调配。显示器之间相互联动,互为备份,能够保证关键显示信息在多种故障模式下依然具备显示能力,以提高系统可靠性。再者,随着显示系统ARINC661标准越来越广泛的应用,对座舱显示系统和用户应用系统进行了定义并规范化,对模块化的航空电子系统的开发具有重要的意义。本文主要研究了显示管理设计中的显示构型管理、显示降级和通讯管理等关键技术。

With the development of integrated avionics technology,many displays in the cabin are no longer independent individuals,and need to be coordinated and dynamically deployed according to specific scenarios and pilots’external operations.Monitors interact with each other and back up each other,which can ensure that critical display information still has display capability in various failure modes,so as to improve system reliability.Furthermore,with the wide application of ARINC661 standard,cabin display system and user application system are defined and standardized,which is of great significance to the development of modular avionics system.This paper mainly studies the key technologies of display configuration management,display degradation and communication management in display management design.
