Title:
POSITION ESTIMATION DEVICE, POSITION ESTIMATION SYSTEM, POSITION ESTIMATION METHOD, AND COMPUTER-READABLE RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2016/084366
Kind Code:
A1
Abstract:
Provided is a position estimation device and the like for accurately estimating the position at which a pressure wave is generated. The position estimation device is provided with: a first cross-correlation derivation means for deriving a first cross-correlation that relates to the pressure of a fluid, on the basis of measured values obtained by measuring the pressure of a fluid flowing through a pipeline network, at at least two locations on the pipeline network; a second cross-correlation derivation means for deriving a second cross-correlation that relates to the pressure of the fluid, on the basis of calculated values obtained by calculating the pressure of a fluid at at least two locations on the pipeline network; and an estimation means for estimating the position at which a pressure wave is generated, on the basis of the difference between the first cross-correlation and the second cross-correlation.
