WATER LEAKAGE DETECTION METHOD, WATER LEAKAGE DETECTION SYSTEM, AND SENSOR TERMINAL USED THEREFOR
To provide a water leakage detection method capable of determining water leakage with high reliability by a single sensor terminal without being affected by restriction of a radio communication environment, and to provide a water leakage detection system, and a sensor terminal used therefor.SOLUTION: Measurement data from a vibration sensor are acquired, an autocorrelation coefficient is obtained from the measurement data, a peak position information set comprising plural peaks of the autocorrelation coefficient is extracted, plural peak position information sets extracted by repeating the above processing plural times are acquired, and water leakage is determined based on a relationship among the plural peak position information sets.SELECTED DRAWING: Figure 4
【課題】無線通信環境の制約を受けずに、単一のセンサ端末で信頼性の高い漏水判定ができる漏水検知方法、漏水検知システム、及び、それに用いるセンサ端末を提供する。【解決手段】振動センサからの測定データを取得し、該測定データから自己相関係数を求め、該自己相関係数の複数のピークからなるピーク位置情報セットを抽出し、以上の処理を複数回繰り返すことで抽出されたピーク位置情報セットを複数個取得し、該複数のピーク位置情報セット間の関係性に基づいて漏水判定を行なう。【選択図】図４
