作为新一代驾驶舱显示系统的行业标准,ARINC661规范推动着整个航空机载电子设备的发展;针对传统的定制式平视显示器显示形式,根据其工作原理,提出了基于ARINC661规范的整体设计方案,并对具体的功能模块及通信过程进行了详细研究;为提高系统的实时性,在UA模块运用了NNAF数据挖掘算法实现对飞行参数的预处理,在渲染模块采用了深度优先搜索算法进行遍历,并给出设计实例对系统进行验证,结果表明基于ARINC661规范的平视显示器开发更具有开放性和扩展性.
As a new generation of success cockpit display system standards, ARINC661 protocol promotes the development of the entire aviation airborne electronic equipment. For the traditional customized forms of HUD display system, according to work requirements of HUD, it puts forward overall design based on ARINC661 protocol and carefully studies on specific functional modules and the mutual communication process. In order to improve the overall system efficiency, it adds NNAF data mining algorithms on UA module to process flight parameters in advance. At the same time, it uses a depth--first search algorithm in rendering module to traverse. In the end, it gives simple example based on ARINC661 to illustrate in order to test and verify the system. The result shows that HUD based on ARINC661 is more scalable and open.
