The invention belongs to the technical field of train section detection, and particularly relates to a subway train vehicle-mounted sensor-oriented detection section identification method, which specifically comprises the following steps of: acquiring vibration acceleration data of a subway train by using a sensor; filtering the longitudinal acceleration and the vertical acceleration of the train collected by the sensor by adopting a multiple moving average filtering method; adding the MMA filtering results of the longitudinal acceleration and the vertical acceleration, and determining a cutting threshold value; judging the dwell time corresponding to the signal less than the threshold # imgabs0 # as the dwell time of the train, and judging the time corresponding to the signal greater than # imgabs1 # as the moment when the train is running in the interval; taking the average value of each stop moment as a segmentation point of the train interval; extracting the curve information, and comparing the curve information with the curve ledger information of each interval; identifying a driving interval; and adjusting parameters of the filtering algorithm. According to the method, the analysis efficiency of the subway train vehicle-mounted data can be greatly improved, and the accuracy of an average filtering processing algorithm is ensured.
本发明属于列车区间检测技术领域,具体涉及一种面向地铁列车车载传感器的检测区间识别方法,具体步骤如下:利用传感器采集地铁列车的振动加速度数据;采用多重移动平均滤波方法,对传感器采集到的列车纵向加速度及垂向加速度进行滤波;将纵向加速度与垂向加速度的MMA滤波结果相加,确定切割阈值;将小于阈值#imgabs0#的信号对应的可判断为列车的停站时间,大于#imgabs1#的信号对应的时间判断为列车正在区间运行的时刻;将每个停站时刻的平均值取为列车区间的分割点;提取出其中的曲线信息,并与各个区间曲线台账信息进行比对;行车区间辨识;调整滤波算法的参数。本发明能够极大提升地铁列车车载数据的分析效率,保证了平均滤波处理算法的准确性。
