WATER LEAK OCCURENCE POSITION ESTIMATION DEVICE, SYSTEM, AND METHOD

摘要

The water leak occurrence position estimation device that is disclosed comprises: a measurement value collection unit that collects a first measurement value from a plurality of sensors arranged in a water distribution pipe network; a measurement value prediction unit that predicts a prediction measurement value in a predetermined water distribution state on the basis of the first measurement value of each sensor; an index value calculation unit that, in response to the reception of event data in which a water leak occurrence is treated as an event, calculates an index value from a second measurement value from each sensor after the water leak occurrence and the prediction measurement value, predicted by the measurement value prediction unit, in the same water distribution state as the water distribution state in which the second measurement value was measured; and a location estimation unit that estimates as the location of the water leak occurrence a region that satisfies the positional relation of the arrangement of the plurality of sensors and a water leak occurrence location based on a magnitude comparison between index values of the plurality of sensors.
