Referring to FIG. 7, in order to control a specific apparatus, the infrared remote controller 100 receives a message for controlling a specific apparatus from the controller 200 (S710). Then, the infrared remote controller 100 acquires the location information of the specific device and the used infrared control code format information from the memory unit 140 (S720) and sets a direction of emitting the signal using the acquired location information (S730) Drives the direction driving unit 131 in accordance with the infrared control code format used by the apparatus and emits the infrared signal (S740).

If the specific device is removed from the home or office, it may also be removed from the infrared remote control 100 for efficiency of control. This removal can be done manually or automatically. In case of manual operation, it can be done by receiving the ID of the device to be removed from the controller 200 and removing information about the ID. In the case of automatic operation, it is possible to automatically remove a device that has not been controlled for a certain period of time. At this time, in order to perform a more reliable operation, the infrared remote controller 100 acquires information about a device to be removed, transmits an infrared signal, confirms whether the device responds to the infrared signal, and then removes the device only when there is no response It is possible.

Unlike the registration and removal process described above, the infrared remote controller 100 may search for and automatically register or remove whether there is a device that can periodically control infrared rays in the home or office.

The infrared remote controller disclosed in the present application can provide a system that can control all the devices that can be controlled by using infrared signals in the home as a device that can be a core of object communication.
