  • Patent number: 9291477
    Abstract: Disclosed is an energy metering system, apparatus and method that enables an energy meter to reduce power consumed in communication when remotely inspecting the energy meter under an energy pricing system changed depending on time. To this end, the energy meter transmits information on energy consumption at only a changed time of energy price, and operates in a power saving mode except the changed time. If the information on the energy consumption is transmitted at the changed time, the information on the energy consumption in each period having the same energy price is secured, and therefore, a central server has no difficulty in calculating an energy consumption rate. Thus, it is possible to minimize power consumed in communication while transmitting all the information on the energy consumption, required in the central server. Particularly, a battery is used longer in an environment using the battery, thereby reducing maintenance/repair cost.

  • Patent number: 9116014
    Abstract: The present disclosure enables comparison of an energy consuming propensity of each energy consumer with that of other energy consumers. To this end, energy usage information of each energy consumer and comparison conditions (size of house, the number of families, energy consuming regions) are collected, and energy consuming propensities of other energy consumers are compared with energy consuming propensity of each energy consumer similar in terms of living environment, and the comparison is shown. A variety of statistical information for comparison is provided through an IHD (In-Home Display) installed at each house, whereby the energy consumers can easily and conveniently evaluate his own energy consuming propensity. An objective evaluation of his or her position related to energy consumption of other energy consumers promotes more active energy conservation and more rational energy consumption by being stimulated by the energy consumption of other energy consumers.
