AI Technical Summary
Technical Problem
Conventional water leak monitoring systems fail to accurately detect leaks when flow rates are small, as they exclude extreme values, leading to incomplete leak determination.
Method used
A water meter that includes a flow measurement unit, pattern information acquisition using AI, zero time period and zero continuous period information acquisition, and a determination unit to identify water leak detection time zones based on zero flow periods, determining leaks even when flow rates are minimal.
Benefits of technology
Accurately detects water leaks even at low flow rates by focusing on time zones with no water usage, enhancing leak detection accuracy and reliability.

Abstract
This water meter comprises: a flow rate measurement unit for measuring the flow rate of water; a pattern information acquisition unit for acquiring use pattern information that is information indicating a usage flow rate of water for each time band on the basis of a measurement result obtained by the flow rate measurement unit; a zero time band information acquisition unit for acquiring, as zero time band information, information pertaining to a time band in which the flow rate becomes zero on each day constituting a prescribed period on the basis of the use pattern information; a zero continuation period information acquisition unit for acquiring, as zero continuation period information, information pertaining to a time band in which the flow rate becomes zero over all days in the prescribed period from the acquired zero time band information; a determination unit that determines a water leakage assessment time band on a day on the basis of the zero continuation period information; and a discernment unit that identifies whether the flow rate measured by the flow rate measurement unit in the water leakage assessment time band is zero, and discerns that there is water leakage in cases where the flow rate is not zero.
