Title:
WATER LEAKAGE DETECTION SYSTEM AND WATER LEAKAGE DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/004713
Kind Code:
A1
Abstract:
Provided is a technology for inferring a water leakage spot of a pipe. A water leakage detection system (20) comprises: a plurality of pressure sensors (230) that are dispersedly disposed in a pipe network; and a monitoring device (200) that infers a water leakage spot in the pipe network. Each of the plurality of pressure sensors (230) transmits, to the monitoring device (200), measurement data of the water pressure at each position in the pipe network. The monitoring device (200) calculates, on the basis of the measurement data at each position in the pipe network, a dynamic water level with respect to a reference value which has been predetermined for each position in the pipe network, and infers the water leakage spot on the basis of a change in dynamic water level at each position in the pipe network.
