基于FlexRay的PLC数话同传网络应用研究

摘要

针对低速PLC通信网络MAC层数话同传支持不足的问题，基于FlexRay静态段定时触发和动态段事件触发思想提出一种用于构建低速PLC数话同传网络的应用层组网协议，详细描述了网络设备的软件和硬件开发过程，并利用串型和星型拓扑研究了网络性能。试验结果表明该网络通信距离长，业务响应时延小。%Since the data⁃voice synchronous transmission support in MAC layer of low data rate PLC transmission network is insufficient,an application layer networking protocol used to construct the low data rate power line communication (LDR⁃PLC) is proposed based on the thoughts of FlexRay static segment timing trigger and dynamic segment event trigger. The soft⁃ware and hardware development processes of the network device are described in detail. The network performance is studied by means of serial topology and star topology. The test results prove this network has the advantages of long communication dis⁃tance,and low business response delay.
