利用LabVIEW和MATLAB的小波函数采集和处理损伤检测数据

Data Acquisition and Processing of Damage Identification Using LabVIEW and Wavelet Function of MATLAB

通过LabVIEW直观的图形化界面将用电测法采集到的有缺陷梁的模拟信号转化为数字信号,在LabVIEW中调用MATLAB中小波函数程序,对噪声信号进行消噪处理。结果表明,该方法消噪效果好,为损伤检测的缺陷定位分析打下了基础。

Analog singles acquired by electrical measurement from damaged girder were changed digital singles based on visible interface of LabVIEW. Wavelet functions of MATLAB were transformed in Lab-VIEW to cancel noise. The results show that the method of canceling noise is better, and this grounds for the bug detection and location of damage identification.
