针对城际列车的特点,从列车自动驾驶、自动开关门及屏蔽门联动、自动折返3个方面阐述了城际列车增加ATO功能的必要性。对城际列车增加ATO后,车辆和ATO之间所需要增加的信号接口进行了分析、梳理和归纳,对车载信号系统为配合ATO功能所新增的设备进行了分析和描述。该接口设计已经在实际项目的试验中得到很好的验证。
According to the characteristics of intercity trains, this paper elaborates the necessity of adding ATO functions to intercity trains from the automatic driving of trains, the linkage of automatic door opening and closing, and the automatic folding back. After adding ATO to intercity trains, the signal interface needed between vehicle and ATO is analyzed, combed and summarized, and the new signal added equipment of car signal system is analyzed and described. This interface design has been well verified in real project trials.
