摘要
针对农村低等级公路检测手段效率低、成本高,以及路面损坏数据积累不足的问题,该文开发了一款基于智能手机的车辆振动数据采集软件,并提出了一种等效于国际平整度指数I_(IRI)的换算计算方法。该方法通过采集车辆行驶过程中的垂直振动加速度信号,经高通滤波和去噪处理后计算上下位移量,进而推导换算后的I_(IRI)'。试验结果表明:尽管智能手机采集的数据精度较专业检测设备稍低,但I_(IRI)'与传统I_(IRI)具有较高的相关性,能够有效反映路面平整度特征,为低等级公路的平整度检测提供了一种经济高效、操作便捷的解决方案,在大范围路面状况趋势监测和初步筛查中具有重要应用价值。
To address the low efficiency and high cost of current detection methods,as well as the insufficient accumulation of pavement damage data on rural low-grade roads,this study developed a vehicle vibration data acquisition application based on smartphones and proposed a conversion method for calculating an index equivalent to the international roughness index(I_(IRI)).Vertical acceleration signals collected during vehicle travel were proposed through high-pass filtering and denoising to calculate the vertical displacement,from which a converted I_(IRI)' was derived.Experimental results show that although the data collected by smartphones has slightly lower accuracy than that collected by professional detection equipment,the proposed I_(IRI)' exhibits a high correlation with the traditional I_(IRI)',effectively reflecting pavement roughness characteristics.This method provides an economical,efficient,and convenient solution for roughness detection on low-grade roads,with significant application value for large-scale pavement condition monitoring and preliminary screening.
