WATER LEAKAGE MONITORING SYSTEM
To provide a water leakage monitoring system which is hardly affected by increasing/decreasing trends of daily minimum flow rate value or seasonal fluctuations, and which does not require changing an initial value.SOLUTION: A water leakage monitoring system 80 calculates, on the basis of first and third quartiles Q1, Q3 of daily minimum flow rate value data for several years, a water leakage determination value H and a water leakage alert determination value h which constitute criteria for determining the occurrence of water leakage. For this reason, extremely large and extremely small daily minimum flow rate values are excluded, and these values are not concerned with the water leakage determination value H and water leakage alert determination value h. Thus, it is possible to determine water leakage by criteria that are stable throughout a year. The water leakage monitoring system 80 equipped with an area specification unit 38 and pertaining to the present invention specifies a water leakage occurrence path and a water leakage caution path on the basis of water leakage occurrence determination and water leakage caution determination with respect to a plurality of measurement units 40 installed in a water distribution path. Thus, it is possible for a manager, etc., to immediately grasp the range of water leakage examination.SELECTED DRAWING: Figure 3
【課題】日最低流量値の増減傾向や季節変動の影響を受けにくく初期値の変更が不要な漏水監視システムを提供する。【解決手段】この漏水監視システム８０は、数年間分の日最低流量値のデータの第１四分位数Ｑ１と第３四分位数Ｑ３とに基づいて漏水発生の判定基準となる漏水判定値Ｈ、及び漏水警戒判定値ｈを算出する。このため、極端に大きな日最低流量値及び極端に小さな日最低流量値は除外され、これらの値は漏水判定値Ｈ、漏水警戒判定値ｈには関与しない。これにより、年間を通じて安定的な基準値による漏水判定を行うことができる。また、エリア特定部３８を備えた本発明に係る漏水監視システム８０は、配水経路上に設置された複数の計測部４０に対する漏水発生判定、漏水注意判定に基づいて漏水発生経路、漏水注意経路を特定する。これにより、管理者等は漏水調査の範囲を即座に把握することができる。【選択図】図３
