夯实机对铁路下轨道镇流器进行夯实时,必须事先确定夯实位置。本文提出了一种峰值检测算法,利用磁传感器信号定位轨道尖峰,进而确定夯实位置。在该算法中,我们通过下采样、滑动窗口、阈值分类和二次峰值搜索来完成峰值检测。我们特别讨论了滑动窗长度、下采样频率、二次搜索窗长度和其他参数对算法性能的影响。在实验中,我们使用一组真实的磁传感器信号来评估算法。与传统方法相比,该算法可将峰值检测的误报和漏检率降至0,同时最大定位误差不大于1 cm。
When a tamping machine is tamping track ballasts under railway, it is necessary to determine the tamping positions in advance. This study proposes a peak detection algorithm to locate rail spikes with magnetic sensor signals, and then determine the tamping positions. In this algorithm, we have performed the downsampling, sliding window, threshold classification, and secondary peak search to complete peak detection. Especially, we discuss how a sliding window length, a downsampling frequency, a secondary-search-window length, and other parameters affect the performance of the algorithm. In experiments, we use a group of real magnetic sensor signals to evaluate the algorithm. Compared with traditional methods, the proposed algorithm can reduce the false positives and misses of peak detection to 0, while the maximum location error will not more than 1 cm.
