摘　　要：针对TTP分布式实时控制系统在节点较多且存在部分节点功能简单时,大量使用TTP节点将使系统成本急剧上升的问题,论文基于TMS320F28335设计了一种多主节点余度、高可靠、高同步精度的时间触发TTCAN总线,并将其作为TTP总线网络的补充子网,实现全网络时钟同步与时间触发,满足高可靠、高确定性大型分布式实时控制系统的控制、同步、加载与成本要求,具有重要的工程应用价值。In view of the problem of TTP distributed real-time control system when there are many nodes and some nodes have simple functions,using a large number of TTP nodes will cause the system cost to rise sharply,based on TMS320F28335,this paper designs a time-triggered TTCAN bus with multi-master nodes redundancy,high reliability and high synchronization precision,and uses it as a supplementary subnet of TTP bus network to realize clock synchronization and time triggering,to meet the requirements of control,synchronization,loading and cost of large-scale distributed real-time control system with high reliability and high certainty.It has important engineering application value.
