座舱多功能显示器显示分配管理设计

Design of Display Allocation and Management for Cockpit Multi-functional Display Unit

目前大尺寸多功能显示器已经取代机械式仪表为飞行员提供信息。提出了一种座舱多功能显示器显示分配与管理的方法。座舱的每个显示器与其他显示器进行信息交换以判断是否存在由于其它显示器故障引起的重要信息的丧失。显示器在飞行员进行显示信息选择操作或者判定出现了重要显示信息丧失时,确定需要显示的信息,并通过预设的显示配置信息得出合适的信息显示布局,将各种信息在有效显示区域进行分配,使得所需显示的信息显示在指定区域中。最后对本文提出的方法进行了仿真验证,证明了该方法的有效性。

Multi-function display unit has replaced mechanical gauge to provide information to crew in cockpit. This paper presents a method of display allocation and management for cockpit multi-function display unit. Each display unit can judge whether there is loss of display information important to crew due to fault of other display unit through information exchange between display units. When crew selects information to display or loss of display information detected, display unit will determine what information to display and the appropriate layout of information display, then allocate all information to be displayed to the demanded area on the screen. In the end, the Matlab simulation proves that the method in the paper is feasible.
