摘要
由于ARINC659总线在通信传输中有着较高的可靠性,采用余度管理设计,在介绍ARINC659间通信原理的基础上,利用ARINC659作为余度管理软件中数据交叉传输的总线,以提高飞行控制计算机系统中的可靠性。在以实时嵌入式操作系统VxWorks为仿真平台的目标机上进行数据交叉增强传输并运行出仿真结果表明:关于交叉传输这一模块的设计是合理可行的,可有效地保证系统的可靠性与容错性能,缩短了软件研发周期。
ARINC659 bus has a higher reliability in communication transmission redundancy management design based on introduced ARINC659 Communication Theory to ARINC659 as redundancy management software in the data bus of cross-transmission, to facilitate the increase in flight control the reliability of the computer system. Enhanced Transmission and run the CCDL results data cross-simulation platform for embedded real-time operating system VxWorks on the target machine. The simulation results show that the CCDL of this module design is reasonable and feasible, can effectively guarantee system reliability and fault- tolerant performance, shorten the software development cycle.
