摘　　要：DMI是司机操作高铁列车控制系统的人机接口设备。高铁列车每一端安装两台DMI,由于两台DMI属于冷备关系,不支持故障无缝自动切换,DMI设备故障必然导致列车制动停车,降低列车运行效率。给出高铁列车DMI热备方案,并详细阐述DMI热备关键技术,包括切换策略、窗口操作热备原理和文本确认热备原理。采用DMI热备方案开发DMI热备功能,实现双DMI热备切换,已得到工程应用和检验,可提高系统可用性,保障铁路运输效率。DMI is the man-machine interface device for drivers to operate the high-speed train control system. At present, two DMIs are installed at each end of a high-speed train. Because the two DMIs are cold standby, seamless automatic switchover is not supported in case of failure. Therefore, the failure of DMI will inevitably lead to brake and stop of the train and reduce the operation efficiency of the train. In this paper, the DMI hot standby scheme of high-speed train is given, and the key technologies of DMI hot standby are elaborated in detail, including switching strategy, hot standby principle of window operation and hot standby principle of text confirmation. The DMI hot-standby scheme has been used to develop DMI hot-standby function and realize dual DMI hot standby switchover. It has been applied and tested in engineering, which can improve the availability of the system and guarantee the efficiency of railway transportation.
