An electronic metering system using a smart terminal according to the present invention is characterized in comprising a complex electronic metering unit and a smart terminal. The complex electronic metering unit receives and stores a registered smart terminal number, and converts electricity use amount information into a digital signal to be displayed on a display unit. Also, the complex electronic metering unit converts gas use amount information, water use amount information, heating use amount information, and hot water use amount information generated in a gas meter, a water meter, a heating meter, and a hot water meter, respectively, into digital signals, and receives and stores the digital signals to be displayed on the display unit. And, the complex electronic metering unit transmits the electricity use amount information, the gas use amount information, the water use amount information, the heating use amount information, and the hot water use amount information to the smart terminal. The smart terminal receives and stores the electricity use amount information, the gas use amount information, the water use amount information, the heating use amount information and, the hot water use amount information from the complex electronic meter to be displayed on a second display unit. Also, the smart terminal calculates electricity charges, gas charges, water charges, heating charges, and hot water charges according to the electricity use amount information, the gas use amount information, the water use amount information, the heating use amount information, and the hot water use amount information, respectively, and displays calculated charges on the second display unit. According to the present invention, it is possible to calculate use charges by using a smart terminal application and provide calculated use charge information along with use amount information through a display unit of the smart terminal. |
