WATER LEAKAGE MONITORING SYSTEM

摘要

There is disclosed a water leakage monitoring system comprising a monitoring device (12) acquiring and storing flow rate and pressure data of a flow meter (5) and a pressure gauge (6a, 6b) located in each water distribution block and a water leakage position estimator (13), the water leakage position estimator (13) including periodic data acquiring means (21) for fetching predetermined-period flow rate pressure data stored in the monitoring device, and for fetching a signal related to a flow rate change and pressure changes expecting a water leakage reaction time calculating means (22) for calculating a pressure reaction time lag between two pressure changes pressure propagation velocity estimating means (23) for estimating a pressure propagation velocity using the pressure reaction time lag and a distance between two pressure gauges located in a water distribution block stored in a pipeline network map data and flow rate change position estimating means (32) for receiving a signal related to the flow rate change, and estimating a flow rate change position using pressure propagation velocity and a flow meter and pressure gauge locating positions of the pipeline network map data.
