Water meter and water supply management system using same
First Claim
1. A water meter comprising:
- a reading unit provided in a meter body to display a flow of water supplied through a water pipe;
a sensing unit provided in the meter body to detect vibrations transmitted through the water pipe;
a conversion unit for converting the vibrations detected by the sensing unit into electric signals;
a frequency analysis unit for analyzing frequency components of the electric signals converted by the conversion unit;
a comparison-processing unit for comparing each of the frequency components of the analyzed electric signals to a predetermined set-up level, and identifying whether each of the frequency components exceeds the predetermined set-up level;
a determination-control unit for calculating a leakage probability on a basis of results from the comparison-processing unit; and
an output unit for outputting a determination result of the determination-control unit as at least one of a video signal and an audio signal.
