摘要
动车组控制系统采用网络来连接各个设备,网络的实时性能直接影响控制系统的性能。本文对TCN标准(IEC61375-1)中的多功能车辆总线MVB的实时性能进行研究,分析其数据通信机制和通信帧类型,建立MVB网络数据通信的仿真模型,根据网络消息数据的通信特点,提出了优化的事件仲裁算法,以期进一步提高MVB网络实时性能,文中对所提算法进行了验证。
The train the networks is one control system uses networks to connect devices of the main factors affecting the performance of in EMUs. The real-time performance of the train control system. The real-time performance of the Multifunction Vehicle Bus specified in the TCN Standards （IEC61375-1） is studied. The frame type and data communication mechanism of the MVB network are analyzed. The model of the MVB com- munication network is established. According to the characteristics of the communication mode of message data, the novel algorithm of event arbitration is provided in order to improve the real-time performance of the MVB network. The constructed model is verified.
