Software

The analysis software is fully functional and easy to use. Not only have conventional analysis functions such as exponential amplification, high pass and low-pass filtering, but also have advanced wavelet analysis functions to eliminate the false signal, revealing the essence of the pile quality
When analyzing data, there are three modification methods in "modification range": "project", "pile" and "hammer", implemented batch processing of measured curve analysis, greatly improving the speed and efficiency of data analysis
Automatic calculating pile defect position, capable of identifying multiple defects on the measured curve
Can perform frequency domain analysis to assist in defect detection and positioning
Can quantitatively calculate the impedance shape of the pile, generate impedance - depth relationship diagram, to help estimate the shape of the pile
Can perform dual velocity analysis to separate upstream and downstream waves, to assist in analyzing existing structures or piles with unknown lengths
The integrity judgment results can be directly output to summary table without manually editing
