Title: PIPE DIAGNOSIS DEVICE, ASSET MANAGEMENT DEVICE, PIPE DIAGNOSIS METHOD, AND COMPUTER-READABLE RECORDING MEDIUM
Abstract:
According to the present invention, a pipe diagnosis device (10) is provided with: a time series data acquisition part (11) which acquires time series data of fluid pressure in a pipe facility to be diagnosed; a pressure variation measurement part (12) which measures, from the time series data of the fluid pressure, the number of instances of pressure variation in the fluid; and a failure risk estimation part (13) which estimates a failure risk of the pipe facility on the basis of the measured number of instances of pressure variation and the strength of the pipe constituting the pipe facility.
