随着ARINC661规范的发展和在航空产品上的成功应用,基于ARINC 661规范进行航空座舱显示系统的开发成为新一代航电系统的发展趋势。航空座舱显示系统内核软件是新一代显示系统的关键。对基于ARINC661规范的通用机载显示系统内核的设计开展了研究,分析了内核的工作原理,研究了内核的组成元素、实现结构。最后通过加载实际的定义文件,成功实现了基于该内核的虚拟仪表的显示。系统的可靠运行,验证了设计的机载显示系统内核是正确的、有效的。
With the development of the ARINC661 standard and its successful application in aviation products, the development of the aviation cockpit display system based on the ARINC 661 standard has become the development trend of the next generation avionics system. Aviation cockpit display system kernel software is the key to a new generation of display system. The design of the kernel of the common on-board display system based on ARINC661 specification has been studied. The working principle of the kernel has been analyzed. The components of the kernel have been studied and the structure has been realized. Finally, by loading the actual definition file, the display of the virtual instrument based on the kernel is successfully achieved. The reliable operation of the system verifies that the designed kernel of the onboard display system is correct and effective.
