摘要

Fluid leakage diagnostic deviceThe component 52 of the disturbance vibration included in the vibration 51 measured at a predetermined location in the pipingBy suppressing using adaptive signal processingIn diagnosing fluid leakage with respect to pipingAssociated with the characteristics of the pipingWhen the performance of suppressing the component 52 of the disturbance vibration satisfies the reference, the acquisition part 41 for acquiring the distribution information 410 representing the distribution result of the value of the parameter in the adaptive signal processing, andBased on distribution informationThe estimator 42 estimates the probability density 420 where the value of the parameter satisfies the criterion existsBased on the probability density 420 estimated by the estimatorA decision section 43 which determines a range 430 for searching the values of parameters in adaptive signal processing andBy providingComponents of the disturbance vibration included in the vibration measured in the pipingIn diagnosing the fluid leakage of a pipe by suppressing an adaptive signal processingImprove the diagnostic accuracy efficiently.
