基于ARINC661的UA软件设计与显示控制研究

摘要

ARINC661 specification defines the interface between the cockpit display control terminal CDS(Display System Cockpit) and the user application (Application User).In the ARINC661 specification,UA is defined.Through the transmission of instructions it drives the CDS to display,which is used to verify the correctness of CDS.Firstly,it analyzes the communication mechanism between CDS and UA,then puts forward the design framework of UA software,and describes the display driving of the airborne sensor data and logical data configuration to CDS,finally,a test example is presented,which indicates the software is reasonable and feasible,and could drive the CDS.%ARINC661规范定义了座舱显控终端CDS(Cockpit Display System)与用户应用(User Ap-plication)之间的接口.规范中定义的UA是通过发送指令驱动CDS进行画面显示,用以校验CDS的正确性.对CDS与UA之间的通讯机制进行了研究,进而提出UA软件的设计框架,研究机载传感器数据与逻辑数据配置对CDS的显示控制,最后给出一个测试示例.示例表明,研究的UA软件是合理可行的,可以实现对CDS的驱动.
