车载列车自动防护系统对空转及滑行的检测与校正方法研究

Research of Slip and Slide Detection and Adjust Method in Onboard ATP

动车组列车运行过程中出现空转、滑行情况时,不影响车载ATP(列车自动防护系统)的正常工作是ATP的技术要求之一。通过分析动车组列车发生空转、滑行的机理,采用轮轴速度传感器与雷达速度传感器相结合的测速模型来检测列车是否发生空转、滑行,并通过列车牵引计算对列车速度、走行距离进行校正。由于本模型以雷达速度传感器来辅助轮轴速度传感器进行空转、滑行的检测,故能有效、即时地校正列车的运行速度,使之不影响车载ATP系统的正常工作。

Its a technique requirement of onboard ATP （au- tomatic train protection） that any slip and slide can＇t effect on ATP＇s good working when multiple train units are in op- eration. By analyzing the mechanism of slip and slide, this paper adopts the velocity measuring model, axle velocity sensor and radar velocity sensor to detect whether the multiple train units have any slip and slide, and adjusts timely the velocity and range of train.
