摘要
针对车载环境使用特点,设计基于以太网的无源光纤网络的车载实时光纤控制网络总体构架。分析了网络的总体结构和时分复用的交换机制,论述了中心节点的MAC设计,并通过数据收发测试和车载CAN总线业务验证了该设计方案稳定可靠,具有很好的实用性。实践结果表明:相比采用传统的定制ASIC芯片设计方案,该网络具有升级灵活,体积小,功耗低的特点。
Aimed at the operation features of vehicle environment, designed a vehicle real-time fiber control network macro architecture based on Ethernet PON （EPON）. Analyze switching mechanism of network macro architecture and time division multiplexing （TDM）. The MAC design of center node was discussed. Then, through the test of datatransmit-receive and vehicle CAN bus, the stability and reliability have been proved, which has good practicability. The test results show that, compared with traditional customized ASIC chip design, the network have the character of upgrade-agility, small form, low power consumption and so on.
