车载ATO的运行等级模式曲线计算是车载ATO的重要功能之一.本文通过分析车载ATO自动调速功能,确定了ATO运行等级模式曲线的设计需求.针对设计需求,结合列车运行状态转移模型,以准点、舒适、节能等为速度控制目标,对不同的城轨列车运行计划(包括运行时间和运行路径)建立了车载ATO运行等级模式曲线的计算模型.通过仿真验证,本文建立的运行等级模式曲线计算模型基本满足车载ATO自动调速功能的设计需求,为自动调速模块提供控制目标曲线.%The calculation function of the operation level type profile is one of the most important functions of the onboard ATO system.In this paper the automatic speed control function of the onboard ATO system was analyzed,the design requirements of the operation level type profile were determined.According to the design requirements and the transition model of train operation states,the computational model of the operation level type profile of the onboard ATO system for different train operation plans (including running time and running path) was established with punctuality,comfort and energy saving as the speed control goals.Through simulation,it is verified that the computational model of the operation level type profile can meet the design requirements of the onboard ATO automatic speed control function and provide the control target profile for automatic speed control modules.
