Abstract
A pipe diagnosis apparatus 10 includes a time-series data acquisition unit 11 that acquires time-series data on pressure of a fluid in piping equipment to be diagnosed, a pressure change measurement unit 12 that measures the number of pressure changes in the fluid from the time-series data on the pressure of the fluid, and a failure risk estimation unit 13 that estimates a failure risk of the piping equipment based on the measured number of pressure changes and a strength of a pipe included in the piping equipment.
Claims20
A pipe diagnosis apparatus comprising:
- a time-series data acquisition unit configured to acquire time-series data on pressure of a fluid in piping equipment to be diagnosed;
- a pressure change measurement unit configured to measure the number of pressure changes in the fluid from the time-series data on the pressure of the fluid;
- and
- a failure risk estimation unit configured to estimate a failure risk of the piping equipment based on the measured number of pressure changes and a strength of a pipe included in the piping equipment.
(canceled)
A pipe diagnosis method comprising:
- (a) acquiring time-series data on pressure of a fluid in piping equipment to be diagnosed;
- (b) measuring the number of pressure changes in the fluid from the time-series data on the pressure of the fluid;
- and
- (c) estimating a failure risk of the piping equipment based on the measured number of pressure changes and a strength of a pipe included in the piping equipment.
A non-transitory computer-readable recording medium that stores a program that contains instructions for causing a computer to execute:
- (a) a step of acquiring time-series data on pressure of a fluid in piping equipment to be diagnosed;
- (b) a step of measuring the number of pressure changes in the fluid from the time-series data on the pressure of the fluid;
- and
- (c) a step of estimating a failure risk of the piping equipment based on the measured number of pressure changes and a strength of a pipe included in the piping equipment.
