Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power monitoring server, and more particularly, to a power monitoring server for reducing system construction cost by receiving power from a distribution board, an external power source, or a renewable energy generation device.
A power monitoring server is a server capable of remote meter reading, bi-directional communication between a power supplier and a consumer, and time-based metering. The power monitoring server provides energy usage information more frequently than the existing remote meter reading that is done once a month by reading the meter every 15 minutes.
However, only the information provided by the power monitoring server has a limitation in saving energy. That is, in the conventional power monitoring server, only the total power consumption of the home can be known, and the power consumption amount of each electronic apparatus in the home can not be known. Therefore, it is often the case that a user can not know which electronic device should be used for saving power consumption. In addition, it may be economically inefficient to attach a watt-hour meter for each electronic device to know the power consumption of each electronic device.

The above and other objects, features, and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings, which are not intended to limit the scope of the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

The event detection unit detects an event occurring in the home appliance based on a change in the power factor provided from the data processing unit (switching on / off of the home appliance or switching of the operating state).
The feature extraction unit extracts the on / off timing of the home appliance and the power consumption pattern of the home appliance from the event detected by the event detection unit. For example, the washing machine differs greatly in the power consumption pattern when the rotating tub is rotated and when the rotating tub is not rotating. Also, since the rotation speed of the rotating tank in the washing and dehydrating steps is greatly different, the power consumption pattern at this time also differs greatly. However, since the television exhibits a substantially constant power consumption pattern without a large change in the power-on state, the power consumption pattern differs greatly from the above-mentioned washing machine. The feature extraction unit extracts a unique feature of the power consumption pattern of the home appliance from the event detection result of the event detection unit.
The device identification unit compares and analyzes the power consumption pattern extracted by the feature extraction unit with the reference data, and determines the type and operation state of the corresponding home appliance through the coincidence between the two data. Particularly, the device identification unit can identify what a plurality of home appliances are when a plurality of home appliances are simultaneously used by using the coefficient of the current harmonic power (CHP) secured by the data collection unit and the data processing unit.
The power determination unit can calculate the individual power amount of the corresponding home appliance by using the type and operation state of the home appliance identified in the apparatus identification unit.
