| 摘 要： | 针对多功能车辆总线网络系统的可靠性问题,采用二模热冗余方法进行多功能车辆总线(MVB)网络冗余环型设计,并提出相应的介质冗余协议;对多功能车辆总线冗余环型网络的可靠性进行理论分析,并基于OMNeT++仿真平台建立多功能车辆总线冗余环型模型,对介质冗余协议进行仿真测试.测试结果表明,当多功能车辆总线网络系统出现故障时,介质冗余协议能实时可靠地进行总线替换,有效提高了多功能车辆总线网络系统的可靠性.

| Abstract: | In order to improve the reliability of the multifunction vehicle bus (MVB) network system, a method of two mode hot redundancy was adopted to design a model of redundancy ring network for MVB, and proposed a correspondingmedia redundancy protocol MRPM. To analyze the reliability of MVB redundant ring network, OMNeT++ simulation platform was used to establish the model of MVB redundancy ring network. The results show that when the MVB redundant ring networkfails, the MRPM can switch to the monitor bus in reliable and real time, making the rebliability of the MVB network system improved effectively. |
