In order to perform this function, the interface device 200 includes a message receiver 210, a storage 220, a first communication unit 230, and a second control unit 240.

Here, the message receiver 210 performs a function of receiving a message from the message transmitter 120 of the home server 100 through serial communication. In this case, serial communication is a communication using a port that a PC generally has. In the present embodiment, the communication between the interface device 200 and the home server 100 is set to the serial communication method, but is not limited thereto. The wired Internet network of the TCP / IP protocol and the wireless Internet network of the WAP protocol are not limited thereto. It includes.

In the case of a TV, the remote control infrared signal controls the operation of the control target device through channel change, on / off operation, and voice control.

The first communication unit 230 performs a function of transmitting control data stored in the storage unit 220 through power line communication or receiving power control from the infrared communication terminal 300 to be described later through power line communication.

The second controller 240 controls the message receiver 210, the storage 220, and the first communication unit 230.

In order to perform this function, the infrared communication terminal 300 includes a second communication unit 310, an infrared transmitter 320, an infrared receiver 330, and a third controller 340.

In this embodiment, the first communication unit 230 of the interface 200 and the second communication unit 310 of the infrared communication terminal 300 are set as a power line communication modem.

The infrared ray transmitter 320 transmits a remote control infrared signal to the control target device 400.

Referring to the function of receiving the remote control infrared signal of the third control unit 340 according to the present embodiment and converting it into control data, an interval between a high signal and a low signal constituting the remote control infrared signal using an interrupt is explained. It is implemented by measuring and converting it into numerical control data.

In the present embodiment, an infrared communication scheme is described as follows.

The infrared communication method used between the control target device and the remote controller is formed in bit units. Bits of 0 and 1 can be distinguished by the time difference in the low state, and a frame is composed of these bit signals to send control signals to the device.

In this embodiment, the third control unit 340 has an advanced RISC architecture and uses a uATMEAG16 board using atmel atmega16l through an In-System Program (ISP) and a JTAG interface (JTAG interface). Although the software was written and implemented, the implementation exceeded the capacity of atmega16l in the process of adding the code for debugging, and the function and interface to receive the infrared signal from the remote control and convert it into control data. It could not have the function of receiving the control data from the control unit 200 and the function of transmitting the remote control infrared signal to the control target device.

Thus, the problem of lack of capacity caused by using the uATMEGA16 board was solved by adopting the atmega128 board having a larger capacity than the atmega16l of the uATMEGA16 board, as shown in FIG.

In this embodiment, the infrared transmitter 320 and the infrared receiver 330 can often think of the Infrared Data Association (IrDA) of a notebook or a mobile phone, but infrared communication used by home appliances installed in a home environment. The method cannot communicate because the hardware performance is different from that of IrDA.

In explaining the reason why the IrDA cannot be used, the wavelength value of the infrared remote signal to be transmitted in the infrared transmitting unit should be the same as the remote controller generally used. Here, it can be seen that the peak wavelength of the wavelength is known as 940 nm for a general remote controller, and the SI5312-H of uATMEGA16 can be used as 950 nm.

In the case of the infrared receiver, it is necessary to use parts with similar specifications as the module received inside the home appliance to receive the signal transmitted from the remote controller and convert it to a numerical value. The KSM-603LM used in uATMEGA16 has a peak wavelength of 940 nm and a bandpass. It can be seen that the center frequency of the bandpass filter (BPF) is 30-40 kHz, preferably 37.9 kHz.
