高速铁路自动驾驶系统地面设备关键技术

Key Technologies of ATO Field Devices for High Speed Railway

为减轻司机劳动强度、进一步降低铁路运输成本,基于高速铁路的列车自动驾驶(ATO)技术应运而生。高速铁路ATO系统是在CTCS-2/3级列控系统的基础上,地面设备通过对既有临时限速服务器(TSRS)、调度集中系统(CTC)、列控中心(TCC)等进行软硬件改造使其具备相关ATO功能。TSRS通过ATO功能扩展具备了车地通信功能、运行计划转发、线路数据发送以及站台门联动;TCC通过继电接口实现对站台门的控制功能及开门防护功能;中心CTC新增运行计划下发及站台门状态显示功能。

The aut0matic train operation（ATO） technology for high speed railway emerges as the railway sector works to lighten the workload of the drivers and to cut transport costs. The ATO system for high speed railway is built on CTCS-2/3. The upgrade of the software and hardware of the temporary speed restriction server（TSRS）, centralized train control system（CTC）, train control center（TCC） and etc. ensures that the field devices accommodate the application of ATO functions. In this process, the TSRS is equipped with new functions like the communication between train and field devices, the forward of operation plan, the sending of line data and the linkage of station doors. With the relay interface, the TCC provides control over the station doors and dooropening protection, while the central CTC can release the operation plan and display the status of the station doors.
