城轨列车启动速度异常的检测方法研究

Start-up Speed Anomaly Detection Method of Urban Rail Train

针对现有城轨列车启动速度异常通过人工判断的方式存在不确定等问题,提出一种基于启动加速度及其标准差数量偏差阈值比对分析的列车启动速度异常的检测方法,研究了该方法的可行性与实施步骤。该方法相对于人工判断方法具有高确定性与高可靠性,应用该方法能及时发现反映在启动速度变化上的列车相关部件故障隐患,在一定程度上有效提高了列车运营安全性。

Aiming to the uncertainty of existing urban rail train start-up speed anomaly judged by human, a train start-up speed anomaly detection method was proposed based on declination threshold of acceleration ratio and its standard deviation. Feasibility and implementation steps of the method were researched. With high certainty and reliability comparing to the human judgment, this method could be used to detect relevant parts hidden faults of train start-up speed variation, which improved the safety of train operation effectively in a certain extent.
