提出了基于惯性基准多传感器综合的路面不平度检测方法,对测量平台的多路加速度信号进行去均值、数字积分和去趋势项处理,计算获得测量平台的精确垂直位移,然后利用提出的路面不平度测量方法完成了路面不平度的测量.针对多数据段拼接问题提出了信号局部基准调整的自适应方法,利用此方法实现了路面不平度的精确测量.通过对比试验证明此方法检测精度较高,完全可以满足工程实践应用.
An inertial reference multisensor comprehensive road surface roughness detection method is proposed. The multi-acceleration signal of the measurement platform is processed by means of de-integration, digital integration and de-trending, and the exact vertical displacement of the measurement platform is calculated. Then, Degree measurement method to complete the measurement of road roughness.Aiming at the problem of multi-data segment splicing, an adaptive method of signal local reference adjustment is put forward, and the accurate measurement of road roughness is achieved by this method.It is proved by comparative experiment that the detection accuracy of this method is high , Fully meet the engineering application.
