Abstract:
1. A plug device in which a plug control circuit unit is embedded in a plug main body of an electrical product, which is inserted in a power source outlet, wherein the plug control circuit unit senses a current corresponding to a power on/off state of the electrical product and selectively supplies an AC power source to the electrical product or blocks the supply of the AC power source according to a time interval during which the sensed current is sustained and an external power-on request, and internal power source lines coupled to terminals of the plug main body are connected to power source supply lines of the electrical product, wherein the plug control circuit unit comprises: a switching unit connected to the internal power source lines; a current transformer configured to surround and couple the internal power source lines for transforming a magnetic field, which is generated by a current flowing through the internal power source lines, into a current value; a current detection unit configured to output a voltage value corresponding to the transformed current value; a radio frequency (RF) wireless unit configured to receive an external plug control wireless signal for controlling transmission of the supply of power to the electrical product; an infrared (IR) wireless unit configured to receive the external plug control wireless signal for controlling transmission of the supply of power to the electrical product; a controller configured to control the switching unit based on the outputted voltage value or in response to the external plug control wireless signal received through one of the RF or IR wireless units, wherein a remote control device having a keypad, a remote RF wireless unit, a remote IR wireless unit, a mode switch, and a remote controller, wherein
