Abstract:
The present invention relates to a multi-function smart-grid unit for saving energy and a method for operating same, in which a separate digital power meter, serially connected to a mechanical power meter, is installed inside the home of a household, and a standby-power outlet is connected to one or a part of one wall power outlet installed on a wall surface, thus allowing the standby-power to be reduced by means of the standby-power outlet to be of help to the home, and the electrical energy consumed by the household within a set area to be easily measured as well as the potential electrical energy consumption within a set area to be predicted by means of the digital power meter to allow electrical energy production to be easily planned.
Abstract:
The present invention relates to: a digital power meter reader system for remote meter reading, which is capable of completing power meter reading at a distance by utilizing conventional mechanical power meter readers provided in respective houses; and a utilizing method using the same. Particularly, the present invention relates to a digital power meter reader system for remote meter reading and a utilizing method using the same, wherein the system can automatically accomplish a series of all the steps of: photographing a mechanical power meter reader with a smart phone or a mobile phone; scanning the photographed data through an embedded application program; transferring the scanned data on an amount of a used current (=amount of used power) to the digital power meter reader through NFC such that the transferred data is computed and confirmed in a management server through a DCU; and re-transferring the data to the digital power meter reader so as to confirm the data. Thus, an amount of power used in each house is capable of being easily calculated even at a distance, and a user of the power who has confirmed the amount in a convenient manner can request corrections in a more precise and safe manner by confirming a difference between the digital power meter reader and the mechanical power meter reader.
