Title:
PIPE INSPECTION SYSTEM, PIPE INSPECTION DEVICE, PIPE INSPECTION METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2016/114136
Kind Code:
A1
Abstract:
The present invention makes it possible to easily detect pipe degradation. A pipe inspection system 1 includes a vibration unit (100), a wave detection unit (210), and a diagnosis unit (220). The vibration unit (100) simultaneously generates waves having different wave modes at a first position on a pipe (300). A wave detection unit (210) detects the waves of the different wave modes at a second position on the pipe (300). A diagnosis unit (220) diagnoses the degradation of the pipe (300) on the basis of the speed of the wave of one wave mode from among the different wave modes, which is calculated using the difference between the detection times of the detected waves of the different wave modes.
