对联锁报告区段状态和车载报告列车位置信息不一致问题的分析与研究

摘要

CTCS-3级列控系统的列车走行累计误差如果过大,有可能造成联锁设备向RBC报告区段占用状态与车载设备向RBC报告列车位置之间存在信息不一致问题,导致列车运行效率降低,影响行车安全.本文针对该问题进行了数学建模,通过对模型的分析研究,说明了问题发生的原因,并提出了降低问题发生概率的方法.%In the CTCS-3, the accumulated error of the train running distance was inevitable when the train was running. If the accumulated error was too large, it was probable to cause the inconsistency problem between section state reported by interlock equipment and train location reported by on board equipment, reduce the train running efficiency and impact the traffic safety. In this paper, the mathematical model was built. With the theoretical analysis to the model, the occurrence reason of the problem was illustrated, the method of reducing the occurrence probability of this problem was put forward.
