Title:
CRACK DETECTING SYSTEM AND CRACK DETECTING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/071241
Kind Code:
A2
Abstract:
Disclosed herein is a crack detection system. The crack detection system comprises an ultrasonic wave sensor tag including a time measurement unit for measuring a current time, an ultrasonic wave detection unit capable of detecting ultrasonic waves applied from the outside, a storage unit storing ultrasonic wave detection information containing a time at which ultrasonic waves are detected by the ultrasonic wave detection unit, a short-range wireless communication module for transmitting the ultrasonic wave detection information to the outside, and a driving electric power supply unit configured to supply driving electric power to said each component; and a crack detection server including a communication module for receiving the ultrasonic wave detection information by forming a communication channel with the short-range wireless communication module, a crack determination unit configured to determine if there occur cracks in a tunnel from the ultrasonic wave detection information.
