摘　　要：研究了新一代汽车总线FlexRay总线的主要特性,通信机制及拓扑结构,提出了一种基于FlexRay总线技术的网络传感器节点的设计方案,并给出了以Atmega128为微控制器,MFR4200为通信控制器和TJA1080通信收发器为核心的总线接口硬件电路设计及相应的节点初始化配置。最后将FlexRay总线和CAN总线进行实时性对比,表明FlexRay总线实时性优于CAN总线。In this paper the design of senor node network based on the FlexRay bus is proposed according to the study on its main features, communication mechanism and topological structure, Bus interface circuit design and node initialization configuration are given base on Atmega128L, MFR4200 and TJA1080. At last with real-time comparision between the FlexRay bus and the CAN bus, it indicates that the FlexRay bus has an advantage over the CAN bus in real-time.
