LEAK DETECTION SYSTEM, VIBRATION DETECTION DEVICE, INFORMATION PROCESSING DEVICE, AND LEAK DETECTION METHOD

WIPO Patent Application WO/2014/156990

A1

This vibration detection device (10) is provided with a vibration detection unit (110), a sensor-side leak determination unit (120), a first transmission unit (130), and a second transmission unit (140). The vibration detection unit (110) detects vibrations transmitted down piping (30). On the basis of measurement results from the vibration detection unit (110), the sensor-side leak determination unit (120) determines whether or not there is a possibility that there is a leak in the piping (30). If the sensor-side leak determination unit (120) determines that there is a possibility of a leak, the first transmission unit (130) transmits provisional leak information to an information processing device (20). Said provisional leak information indicates that there is a possibility of a leak in the piping (30). If waveform-request information indicating a request for waveform data for the vibrations is received from the information processing device (20), the second transmission unit (140) transmits waveform data measured by the vibration detection unit (110) to the information processing device (20).
