中文摘要：

列车车载监控系统的正常运行对轨道交通的安全起着至关重要的作用。列车车载监控系统一般由摄像机、硬盘录像机、交换机和触摸屏监视器等设备组成，承担实时监控列车环境、存储视频录像等重要责任。列车车载监控系统软件运行在触摸屏监视器中，是整个车载监控系统的核心控制软件。动态编组处理功能是列车车载监控系统软件的重要组成部分，该功能在列车动态编组运行时，保证列车车载监控系统正常工作。所论述的动态编组列车车载监控系统软件目前已经在某地铁项目中得到应用。

英文摘要：

Train on-board monitoring system plays a vital role in the safety of rail transportation.It is usually made up of camera,digital video recorder （DVR）,switch,touch screen monitor （TLCD） and other devices,which takes the responsibilities of real-time monitoring environment of train, storing video and so on.The train on-board monitoring system software which runs in the TLCD is the core control software of the system.The dynamic grouping handle function is a key part for the whole train on-board monitoring system software.When trains run in dynamic grouping mode,this function guarantees that the monitoring system works normally.The introduced on-board monitoring system software for dynamic grouping train has already been used in a subway project.
