高速铁路接触网参数特征提取

Extraction of Characteristics of OCS Parameters for High Speed Railways

为实现高速铁路接触网状态的综合评价,基于接触网参数的多样性,需对接触网状态参数数据进行预处理及特征提取。本文提出AR谱模型与模糊分析相结合的方法,利用AR谱模型绘制接触网线谱,对接触网线谱峰值处的检测数据进行分析,运用模糊分析求出各参数在整体评价体系中所占权重,为接触网的状态评估提供依据。

In order to realize the comprehensive assessment of OCS status for high speed railways, on the basis of varieties of OCS parameters, it is required to perform preprocessing of data of OCS status parameters and extraction of the characteristics. The paper introduces that a method combining of AR spectrum model and fuzzy analysis is adopted, among which, AR spectrum is to plot the OCS spectrum and analyze the inspection data at peak of OCS spectrum, fuzzy analysis is to calculate the weighting of various parameters in the whole assessment system, these will provide the basis for assessment of OCS status.
