摘　　要：传统的时间触发型ARINC659背板总线无法适应高速数据通信的需求,随着航天事业迅猛发展,建立规范化的单机内数据总线越来越有必要性。文中首先介绍了SpaceAGE串行背板总线,它克服了并行数据总线的可靠性差、通讯速率低等缺点,且具备标准化的遥测采集接口和优秀的配电管理等特点;其次介绍了背板速度更快的波分交换和环形拓扑光纤背板;最后分析应用的前景及挑战,希望对航电背板设计有一定的参考。The traditional Time-triggered ARINC659 backplane bus can't meet the need of high-speed data communications.With the rapid development of the aerospace industry,standard backplane data bus architecture becomes more and more necessary.Firstly,the NASA SpaceAGE serial backplane bus is introduced,which uses dual star topology and overcomes the disadvantages of parallel bus including poor reliability,low communication rate,etc.It has a standardized telemetry bus and excellent power distribution capability.Secondly,the optical serial backplane based on a coarse wave division multiplex mesh network and the optical serial bus based on a redundant,cross-strapped,serial ring are introduced,which have bigger bandwidth and lower EMI.Finally,prospects and challenges in the application are analyzed,which can be a reference for avionics design.
