摘要
ARINC 659背板数据总线是一种高可用、高完整、支持鲁棒的时间分区和空间分区的容错串行总线,它是ARINC 651标准定义的综合化模块化航空电子系统的关键技术。深入分析了航空电子系统综合化对背板总线的要求,概述了ARINC 659背板数据总线体系结构、介质访问机制、同步机制等规范,详细介绍了ARINC 659背板数据总线的典型应用系统,探讨了ARINC 659背板数据总线特性与应用前景。
ARINC 659 backplane data bus is of high reliability and high- integrity designed to provide fault tolerance and robust partitioning of the time and the memory space. It is a key component of the integrated modular avionics system as defined in ARINC Report 651. Firstly, the requirement of the backplane data bus for the integrated modular avionics is presented. Secondly, the ARINC Specification 659 is studied ,which is mainly on the system architecture, the media access protocol, synchronization. Thirdly, the representative application systems of the ARINC 659 backplane data bus are given. Finally, we propose the application trend of ARINC 659 backplane data bus.
