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

摘要

This fluid leakage diagnosis device 40 comprises an identification unit 41 for using wave measurement information 500 expressing a wave measured in a pipe 50 to identify the position of the origin 51 of the wave, a detection unit 42 for using structural information 501 for the pipe 50 to detect a structural cause 52 of the wave at the position of the origin 51 identified by the identification unit 41, a determination unit 43 for determining whether the change over time in the wave measurement information 500 satisfies a condition, and a diagnosis unit 44 for diagnosing fluid leakage in the pipe 50 on the basis of 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.
