WATER LEAKAGE STAGE DETECTION METHOD IN PULSE OUTPUT OF WATER METER
To provide a low-cost and simple method for detecting water leakage using only a pulse output of an impeller-type water meter.SOLUTION: The reception of a pulse signal at each reference time is monitored using a plurality of water leakage determination parameters, which are composed of the reference time, the number of times of determination, an amount of determination, a count within a determination period, and the number of times of succession, corresponding to a degree of water leakage. When the number of determinations is received continuously, or when a count value within the determination period reaches the amount of determination, it is determined that a water leakage has occurred. Furthermore, when water leakage of the same degree is detected twice, a parameter of the number of times of determination for that degree is automatically updated to a value obtained by adding 1 to the maximum number of times of succession.SELECTED DRAWING: Figure 2
【課題】 低コストで簡易な、羽根車式水道メータのパルス出力のみで、漏水を検出する方法を紹介する。【解決手段】 漏水度合いに対応した、基準時間、判定回数、判定量、判定時間内計数、連続回数で構成される、複数の漏水判別パラメータにより、基準時間ごとのパルス信号の受信を監視し、判定回数を連続して受信しているとき、又は判定時間内の計数値が判定量となったときに漏水判定とする。更に、同一度合いの漏水を２回検出した場合に、その度合の判定回数パラメータを、最大連続回数に１加算した値へ自動更新する。【選択図】図２
