When performing maintenance such as various annual inspections and monthly inspections in the construction and machinery fields, it is possible to identify various initial failure points and failure details compared to daily operation, which is important.
Preventing breakdowns will lead to cost reduction and time reduction for repairs.
Anomaly detection by concrete hammering sound
When conducting annual inspections to investigate the degree of concrete deterioration, it is possible to detect the presence or absence of cracks and cavities in concrete, and it is a hammer-based tapping sound measuring instrument for checking the size, depth, orientation, etc. of defects.
"GD Similarity" can be applied and accuracy can be improved.
It can be used to detect initial abnormal waveforms and minute frequency changes from the flowing sound in the pipe, and to identify failures due to cavitation, surging, etc., and damaged parts of the pipe due to water hammer.
