T / C Registration ID-1 Area: This area is used to prevent malfunctions when the power adapter is re-registered. It is used to change the registration position of the power adapter.

Group area: This area indicates the group to which the power adapter is registered. For example, if the group is divided into three groups A, B, and C, the values A = 000, B = 001, and C = 010 are assigned.

T / C registration flag area: This area indicates whether or not the power adapter is registered. It is always set to a value of "1" once the power adapter is registered.

End bit area: This area indicates the end of data, and is composed of 4 bits of "0101" which is an inversion value of the start bit.

Error check (CRC) area: Area used for error checking of T / C registration ID area, T / C registration ID-1 area, group area, and T / C registration flag area.

When the registration process of the remote controller for the power adapter is completed as described above, a registration information signal having the above format is wirelessly transmitted to the power adapter in order to assign a unique number to the corresponding power adapter. The remote control unit unilaterally transmits the registration information signal up to five times as shown in FIG.

Meanwhile, when the registration information signal is received, the corresponding power adapter extracts the registration information included in the received signal and stores the registration information in its own memory. In this way, since a unique number is assigned to the power adapter, the power adapter may supply or cut off power to the home appliance through a power opening / closing switch according to a wireless control signal transmitted from a remote controller to control the power applied to the home appliance. Can be.

That is, as shown in FIG. 6, the wireless control signal includes ON / OFF control for controlling the operation of the power adapter as well as the used remote control ID area, T / C control ID area, T / C control ID-1 area, and group area. It includes a bit area. The power adapter compares the unique number included in this wireless control signal with the unique number stored in its memory, and if both unique numbers match, the power adapter opens and closes the power according to the control code included in the ON / OFF control bit area. The switch is controlled to supply or cut off power to the home appliance.

As described above, the present invention allocates a unique number to each power adapter at the time of production of the wireless power adapter system, and stores the assigned unique number in the remote control and provides the user with the power adapter to be controlled by the user. By registering and wirelessly transmitting this registration information to the power adapter, the power adapter and the remote controller can be used universally by assigning a unique number to each power adapter.
