【摘要】 列车通信网(TCN)是在开式列车上使用实时协议的数据通信局域网,它由多功能车辆总线MVB和绞线式列车总线WTB构成。列车通信网采用了强有力的数据差错控制措施和监视数据帧,保证了高速运行列车的安全。该文分析了列车通信网中的各种安全性措施,并与传统局域网进行了比较。更多还原

【Abstract】 Train Communication Network is a data communication local network which uses real - time protocols in open train. It covers multifunction vehicle bus and wire train bus. TCN adopts stronger data error control and provides powerful supervisory frame to insure the security of high - speed train. The paper analyzes the security methods which adopt in the TCN and compares them to the traditional local area network.更多还原
