摘　　要：CTCS3-CTCS2等级转换是高速铁路列车运行控制系统的重要运营场景之一,在联络线长度过短或联络线存在大号码道岔等不利线路条件下设置CTCS3-CTCS2等级转换点时,由于在部分进路及临时限速场景下CTCS3系统与CTCS2系统计算控车模式曲线的逻辑存在差异,如果CTCS3-CTCS2等级转换预告点和执行点的位置设置不合理,可能导致列车在等级转换时产生超速制动的风险。对等级转换过程中车载计算控车模式曲线的差异、CTCS3系统与CTCS2系统控车逻辑的差异性进行分析;结合实际线路探讨列车在CTCS3-CTCS2等级转换中可能存在的问题,对选用线路中不同位置的应答器作为等级转换预告点或执行点的方式进行综合分析和测试,提出了解决方案;并通过理论分析及多种车型的仿真试验验证了方案的可行性,对CTCS3-CTCS2等级转换预告点及执行点的设置要求进行归纳和总结。CTCS3-CTCS2 level transition is one of the significant operation scenarios of high-speed railway train operation control system.When the CTCS3-CTCS2 level transition position is set under unfavorable line conditions such as the length of railway connecting line is too short or there is a large-size switch on the connecting line,the logic of calculating the control mode curve of CTCS3 system and CTCS2 system is different in some routes or temporary speed restriction scenarios.If the location of CTCS3-CTCS2 level transition forecast position and execution position is set improperly,it may lead to the risk of overspeed braking during level transition.In this paper,the differences in train computing control mode curves and the differences in control logics between CTCS3 system and CTCS2 system in the process of level transition are analyzed.Combined with the actual lines,the possible problems in CTCS3-CTCS2 level transition are discussed.At the same time,the method of selecting the balises at different places as the forecast positions or execution positions is analyzed and tested.The solution is proposed and its feasibility is verified by theoretical analysis and simulation tests of various trains.The setting requirements of CTCS3-CTCS2 level transition forecast position and execution position are summarized.
