WATER LEAKAGE GENERATION POSITION ESTIMATION APPARATUS, SYSTEM, AND METHOD
PROBLEM TO BE SOLVED: To estimate a water leakage generation position even when a variation in a water distribution state caused by another factor has generated.SOLUTION: A water leakage generation position estimation apparatus includes: a measurement value collection unit for collecting first measurement values of a plurality of sensors disposed in a water distribution pipe network; a measurement value prediction unit for predicting a prediction measurement value in a predetermined water distribution state on the basis of a sensor's first measurement value; an index value calculation unit that, in response to reception of event data taking generation of a water leakage as an event, calculates an index value from the sensor's second measurement value after the generation of the water leakage and a prediction measurement value predicted by the measurement value prediction unit in the same water distribution state as a water distribution state in which the second measurement value has been measured; and a position estimation unit for estimating an area satisfying positional relation between arrangement of the plurality of sensors and a water leakage generation position based on magnitude comparison of index values between the plurality of sensors, as a position at which the water leakage has been generated.SELECTED DRAWING: Figure 1
