摘要
为验证不同速度等级、不同列车长度下的点式列车自动控制(ATC)系统是否能够满足城市轨道交通的运营能力需求,依据点式ATC系统特点及信号系统设计的相关要求,推出列车在区间和车站最小追踪间隔的计算模型,并根据计算模型给出了能力影响因素,得出最小追踪间隔与最高运行速度及列车长度之间的关系。通过仿真计算,得出不同速度等级、不同长度下列车运行的最小追踪间隔,验证了计算模型的合理性,并给出了不同速度等级及列车长度下点式ATC系统的适用情况。
In order to verify whether the intermittent automatic train control(ATC)system with different speed grades and different train length could meet the operational capacity demand of urban rail transit,this paper introduced the calculation model of the minimum tracking interval between trains and stations based on the characteristics of the intermittent ATC system and the related requirements of the signal system design,according to the calculation model,gave the influencing factors of capacity,and obtained the relationship between the minimum tracking interval and the maximum running speed and train length.Through simulation calculation,the minimum tracking interval under different speed grades and lengths of trains was obtained.The rationality of the calculation model was verified,and the application of intermittent ATC system under different speed grades and train lengths was given.
