Title:
DEVICE, METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2017/094846
Kind Code:
A1
Abstract:
Provided is a device that can accurately predict the deterioration trend of a pipe. The device is characterized by including a plurality of detection means 10, a cross-correlation function calculation means 22, a deterioration level calculation means 24, and a deterioration prediction means 25. The device is further characterized in that he plurality of detection means 10 detect undulations at at least two locations in a pipe in which a fluid flows, the cross-correlation function calculation means 22 calculates a cross-correlation function for the pipe on the basis of the undulations at at least two locations in the pipe detected by the plurality of detection means 10, the deterioration level calculation means 24 calculates the deterioration level of the pipe on the basis of the shape of the cross-correlation function for the pipe, and the deterioration prediction means 25 predicts the deterioration trend of the pipe on the basis of the temporal change of the deterioration level.
