1) piling sound
锤击声音
1.
On the basis of the analysis of fast Fourier transform and some basic statistical variables,the piling sound is analyzed in frequency domain;then the character,mean absolute deviation,and corresponding parameters on the piling sound recognition are acquired;thus an algorithm can be developed to count the number of piling sound by rule and line.
针对常规人工记录锤击数的低效情况,在此将打桩现场采集的声音信号运用快速傅立叶变换到频率域,对频谱进行多个统计量的分析,并同时考虑了锤击声音可能受到附近噪音的干扰,从中选取平均绝对值偏差这个统计量作为识别锤击次数的特征,由此探测得到一组可以较为精确识别锤击数目的特征参数,实现了锤击数准确识别的自动化。
2.
A digital system,which is used to recognize the number of piling sound,is firstly put forward.
继而在考虑锤击声音可能受到附近噪音污染的情况下,确定出一组精确识别锤击次数的参数。
