Large-gap pavement structure depth detection method based on sound processing technology
The invention provides a large-gap pavement structure depth detection method based on a sound processing technology, and the method comprises the steps: carrying out the preprocessing of a sound signal based on the sound processing technology, guaranteeing the accuracy of the signal, carrying out the calibration according to a plurality of reference values in a structure depth detection process, and taking the distance between a microphone and a knocking point as an impact factor. The sound characteristic parameters of the receiving equipment are uniformly evaluated in the same distance environment, errors caused by different distance influence factors are eliminated, and the result precision can be greatly improved. According to the position of the microphone and the sound path distance difference of sound transmission, the coordinate of the position to be detected can be accurately positioned through establishment of the data model, the workload of obtaining the information of the position to be detected is avoided, the road surface pollution caused by detection means such as a sanding method is avoided, and the detection and evaluation efficiency is greatly improved; the calculation result can provide a theoretical basis for pavement disease cause analysis, construction condition evaluation, project acceptance and the like, and the technical content is simple to operate and easy to implement.
本发明提供一种基于声音处理技术的大空隙路面构造深度检测方法，基于声音处理技术，对声音信号进行预处理，保证信号的准确性，在构造深度检测过程中，根据多个基准值进行标定，以麦克风与敲击点距离作为影响因子，将接收设备的声音特征参数统一在相同距离环境中进行评判，消除不同距离影响因子带来误差，可以大幅度的提高结果的精度。本发明根据麦克风位置，以及声音传播的声程差，通过数据模型建立，可以准确定位出待检测的位置坐标，避免了获取待检测位置信息工作量，避免铺砂法等检测手段对路面污染，大幅度提高了检测与评价的效率，计算结果可以为路面病害成因分析与施工状况评定、工程验收等提供理论依据，技术内容操作简单、易于实现。
