一种基于GPS速度的机车自动轮径校正方法
|
摘要
提出了一种利用GPS速度进行轮径自动校正的方法,设计了进入轮径校正的判断条件和速度时序补偿方法,解决了从包含大量噪声和时延的GPS信号中提取有效速度信号的难题,实现了机车轮径高精度(误差不大于2 mm)自适应性校正。该方法的有效性、准确性在南非电力机车项目上得到了验证。
A method of automatic correction of wheel diameter using GPS speed was proposed,and the judgment conditions for entering the correction of wheel diameter and the compensation method of speed sequence were designed.The problem of extracting effective speed signals from GPS signals containing a lot of noise and time delay was solved,and the high precision(error is less than2 mm) adaptive correction of locomotive wheel diameter was realized.The validity and accuracy of this method have been verified in the South African electric locomotive project.
