ARINC661显控指令快速验证方法

针对ARINC661座舱显示系统中显示控制单元在开发阶段验证指令困难的问题,设计了一种解决方法.该方法不需要搭建联试环境,仅在控制指令开发的计算机上即可完成验证.该设计充分利用ARINC661通用内核进行扩展,在通用内核DF加载、指令解析、人机交互、画面渲染等基本功能的基础上,增加显示设备、虚拟UA的管理功能,既保证了辅助组件与实际显示画面的一致性,又能方便地模拟各种机载显示设备.该设计用直观的显示结果来验证控制指令的正确性,使设计人员能够方便快速地测试已开发指令的正确性,从而缩短试验周期,具有良好的适用性、扩展性和可靠性.

Quick Verification Method of User Application Command Based on ARINC661

A solution is designed to solve the problem that user application command based on ARINC661 specification is difficult to be verified during the development phase.This method does not need to build a joint debugging environment,and user application command can be verified on the computer used to develop the commands.This design made full use of the generic kernel based on ARINC661.On fundamental functions,such as loading DF,parsing instructions,event notification and rendering,the management functions of display device and UA were added.It not only ensures the consistency of the auxiliary components and the actual display screen,but also facilitates the simulation of various airborne display devices.The correctness of the user application command is verified by visual display results,which enables the designers to test the correctness of the developed commands conveniently and quickly.This design has good applicability,scalability and reliability,and can shorten the test cycle.
