STANDBY POWER CUT-OFF APPARATUS AND METHOD THEREOF

摘要

The present invention relates to a standby power cut-off apparatus which can prevent unnecessary power consumption by cutting off standby power when an external device connected to a power outlet is not being used. In order to realize this invention, the standby power cut-off apparatus comprises: a power outlet which is connected to a commercial power line and has one or more sockets which supply power to an external electrical device connected by a power plug; a switching unit which is connected to the commercial power line and controls application of an electric current from the commercial power; a current detecting sensor which detects electric current flowing through the commercial power line; a control unit which includes a microcontroller in which power consumption patterns of various electrical devices are stored as reference power consumption patterns in the form of a program in a ROM, and if the current detecting sensor detects a current signal, then the detected current signal is converted to a pattern, which is compared with the reference power consumption patterns to control the operation of the switching unit; and a load sensing unit which is connected to the commercial power line and senses whether or not an electrical device is connected to the socket of the power outlet.
