FLUID LEAKAGE DIAGNOSIS DEVICE, FLUID LEAKAGE DIAGNOSIS SYSTEM, FLUID LEAKAGE DIAGNOSIS METHOD, AND RECORDING MEDIUM STORING FLUID LEAKAGE DIAGNOSIS PROGRAM

摘要

A fluid leakage diagnosis device 40 includes: an identification unit 41 for using wave measurement information 500 expressing a wave measured in a pipe 50 to identify a position of an origin 51 of the wave; a detection unit 42 for using structural information 501 of the pipe 50 to detect a structural factor 52 of the wave at the position of the origin 51 identified by the identification unit 41; a determination unit 43 for determining whether a time shift in the wave measurement information 500 satisfies a condition; and a diagnosis unit 44 for diagnosing fluid leakage in the pipe 50 based on a detection result from the detection unit 42 and a determination result from the determination unit 43. As a result, this fluid leakage diagnosis device enhances the accuracy of fluid leakage diagnosis for a pipe accomplished through measurement of a wave produced in the pipe.
