| 摘 要： | 针对汽车控制系统中实时通信的高性能需求,文中采用以CAN总线作为网络底层协议,以SAE J1939协议和TTCAN协议作为网络的上层协议的分层网络结构.TTCAN是一种基于时间触发机制的协议,因此这种网络结构不仅可以实现系统各节点之间高速数据共享,同时能够提高网络带宽的利用率,而且在消息的实时性能方面得到很好的改善.在测试当中,取得了良好的效果,充分证明了方案的可行性.

| Abstract: | In the light of vehicle control system needing the high-performance of real-time communication,this paper introduced a hierarchical network structure.It used CAN-bus as the underlying protocol,SAE J1939 protocol and TTCAN as the upper protocol.TTCAN was a time-based trigger mechanism protocol,so the network system not only realized high-speed data sharing between nodes and increased the utilization rate of the network bandwidth,but also improved the real-time performance.It has good results in test,fully pr... |
