Abstract

PURPOSE:To obtain a storage water gauge monitor capable of accurately diagnosing the abnormality of a water gauge by providing a flowing-water quantity arithmetic section, a storage-water quantity arithmetic section, a final-effluent quantity arithmetic section and a storage water gauge abnormality diagnostic section. CONSTITUTION:An inflow Qi is computed by a flowing-water quantity arithmetic section 10 from a river stage Hr observed by a river water gauge 4 in the upstream of a dam. Each measured value is taken in from a gate opening gauge 5 and a storage water gauge 6, and the quantity of a final effluent Qo is computed by a final-effluent quantity arithmetic section 11 from the gate opening P and a water stage Hc. When the storage water gauge 6 is operated at all times due to trouble, a deviation is generated between a water stage Hcr expected from the variation of the quantity of a final effluent Qos and the quantity of flowing water Qis periodically calculated by a storage- water quantity variation-value arithmetic section 13 and the water stage Hc input by a water-stage input section 9, the deviation is processed by a comparison section 15, an alarm is displayed and output by an alarm display section 16 when the deviation exceeds an alarm reference value Hk or more, and an operator is informed of the abnormality of the storage water gauge 6.
