본 발명은 가정자동화(Home Automation)시스템에 있어서 가전제품을 제어하기 위한 제어명령을 전력선을 통해 전송하는 전력선 반송시 신호변환장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a signal conversion apparatus for carrying a power line that transmits a control command for controlling a home appliance through a power line in a home automation system.

일반적으로 가정자동화시스템은 가정내 가전제품이나 다른 구동장치들을 원격제어하는 것을 말한다. 상기 가정자동화 시스템에 있어서 가전제품들을 제어하는 방식은 적외선 원격제어방식과 전력선 반송시 제어방식이 있으며 이들 제어방식들을 설명하면 다음과 같다.In general, home automation system refers to remote control of home appliances or other driving devices. In the home automation system, home appliances are controlled by an infrared remote control method and a power line transfer method. These control methods will be described below.

적외선 원격제어는 리모콘 송신기가 제어할 신호를 수신기가 내장된 전원모듈로 무선전송하면 이를 수신한 전원모듈은 그 신호에 따라 릴레이나 반도체 전력제어소자를 제어함에 따라서 가전기기의 작동을 제어하게 된다. 전력선 반송식 제어기가 제어신호를 전력선을 통하여 전원모듈에 전달하면 전원모듈은 수신된 신호에 따라 가전기기를 릴레이나 반도체 소자를 이용하여 제어해 준다. 이들 전원모듈들은 마이콤이나 집적회로를 이용하여 수신된 신호를 분석하며 그 결과에 따라 동작을 하게 된다.Infrared remote control wirelessly transmits a signal to be controlled by the remote control transmitter to a power module having a built-in receiver, and the power module receiving the remote control controls the operation of the home appliance according to the control of the relay or the semiconductor power control device. When the power line carrier controller transmits a control signal to the power module through the power line, the power module controls the home appliance using a relay or a semiconductor device according to the received signal. These power modules analyze the received signal using a microcomputer or integrated circuit and operate according to the result.

그러나 적외선 리모콘 제어방식은 리모콘 송신기를 자유롭게 이동하면서 사용할 수 있으나 적외선이 미치는 범위내에서 제억 되기 때문에 제어영역이 협소하다. 그리고 전력선 반송시 제어방식은 적외선 리모콘 제어방식보다 그 적용 영역이 훨씬 넓지만 제어기는 콘센트가 있는 위치에서만 설치 가능하여 적외선 리모콘 제어 방식보다 다소 제어에 불편함이 있다.However, the infrared remote control method can be used while freely moving the remote control transmitter, but the control area is narrow because it is stored within the range of infrared rays. In addition, the control method for power line transfer has a much wider application area than the infrared remote control method, but since the controller can be installed only at the outlet, the control method is somewhat inconvenient to control the infrared remote control method.

따라서 본 발명의 목적은 적외선 원격제어신호를 전원 전송하게 하여 넓은 범위에 걸쳐 제어가 용이한 전력선 반송식 신호변환장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a power line carrier signal conversion device that is easy to control over a wide range by allowing the infrared remote control signal to be transmitted power.

이하 본 발명을 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명의 회로도로서 전력선(L1,L2)와, 상기 전력선에 접속되어 가전제품을 제어하기 위한 전원모듈을 구비한 가정자동화 시스템에 있어서, 시스템을 제어처리하기 위한 마이콤(10)과, 적외선 원격송신기(11)와, 적외선 제어신호를 수신하기 위한 포토다이오드(PDI)와, 상기 포토다이오드(PDI)의 출력을 증폭하여 상기 마이콤(10)에 공급하는 증폭부(12)와, 상기 전력선(L1,L2)에 접속되어 전원의 동기를 검출하여 상기 마이콤(10)에 공급하기 위한 동기검출부(13)와, 상기 마이콤(10)로부터 인입된 정보를 변조하여 상기 전력선을 통해 송출하거나 상기 전력선(L1,L2)쪽으로부터 인입되는 신호를 복조하여 상기 마이콤(10)에 공급하기 위한 변복조부(14)와, 상기 변복조부(14)과 상기 전력선(L1,L2) 사이에 접속되어 상기 변복조부(14)와 전력선(L1,L2)를 중계하기 위한 중계트랜스포머(IFT)로 구성한다.1 is a circuit diagram of the present invention, a power supply (L1, L2), a home automation system having a power module for controlling home appliances connected to the power line, the microcomputer 10 for controlling the system, An infrared remote transmitter (11), a photodiode (PDI) for receiving infrared control signals, an amplifier (12) for amplifying the output of the photodiode (PDI) and supplying it to the microcomputer (10), and the power line And a synchronization detector 13 for detecting the synchronization of the power supply and supplying it to the microcomputer 10, and modulating the information drawn from the microcomputer 10 and transmitting the same through the power line or the power line. A demodulation section 14 for demodulating a signal drawn from the (L1, L2) side and supplying the demodulated signal to the microcomputer 10, the demodulation section 14 and the power line L1, L2, and the demodulation section To relay 14 and power lines L1 and L2 Constitute a relay transformer (IFT).

상술한 제1도를 참조하여 본 발명을 상세히 설명한다.The present invention will be described in detail with reference to FIG.

적외선원격송신기(11)는 운용자가 입력한 제어명령에 대한 적외선신호를 발생하여 송출한다. 이때 적외선 신호를 수광하는 포토다이오드(PDl)의 상기 적외선을 전기적신호로 변환하여 증폭부(12)를 공급한다.The infrared remote transmitter 11 generates and transmits an infrared signal for a control command input by an operator. At this time, the infrared ray of the photodiode PDl receiving the infrared signal is converted into an electrical signal to supply the amplifier 12.

증폭부(12)는 상기 포토다이오드(PDl)의 출력을 전압변환하고 증폭한 다음 일정주파수 대역에 대하여 여과한 후 파형정형하여 펄스형태의 제어신호를 마이콤(10)에 공급한다. 상기 제어신호는 원격송신기(10)에서 송출된 데이타 형태와 동일하다.The amplifier 12 voltage converts and amplifies the output of the photodiode PDl, filters the signal for a predetermined frequency band, and shapes the waveform to supply a control signal in the form of a pulse to the microcomputer 10. The control signal is the same as the data type sent from the remote transmitter 10.

그리고 동기검출부(13)는 전력선(L1,L2)상에 흐르는 전원전압의 ＂0＂에 교차되는 순간을 검출하여 듀티비가 균등한 동기신호를 발생하여 마이콤(10)에 공급한다.The synchronization detector 13 detects the moment when the power supply voltage flowing on the power lines L1 and L2 intersects [0], generates a synchronization signal with an equal duty ratio, and supplies the same to the microcomputer 10.

또한 마이콤(10)은 상기 증폭부(12)로부터 인입된 제어신호를 자체내에 내장된 프로그램에 의해 처리한 다음 처리된 결과를 동기검출부(13)로부터 인가되는 동기신호에 맞추어 변복조부(14)에 공급한다. 그리고 제어대상에 대한 제어신호송출시 해당된 발광소자(LED)를 점등시켜 작동중인 제어대상을 표시한다. 그러면 변복조부(14)는 상기 마이콤(10)으로부터 공급되는 신호를 자체내에서 발생된 반송파신호에 의해 진폭편이변조(Amplitude Shift Keying)하여 중계트랜스포머(IFT)에 공급한다.In addition, the microcomputer 10 processes the control signal drawn from the amplifying unit 12 by a program embedded in the self, and then processes the processed signal to the modulation / demodulation unit 14 in accordance with the synchronization signal applied from the synchronization detecting unit 13. Supply. When the control signal is transmitted to the control object, the corresponding light emitting device (LED) is turned on to display the control object in operation. The modulator 14 then modulates the signal supplied from the microcomputer 10 to the relay transformer ITF by amplitude shift keying by the carrier signal generated therein.

이때 중계트랜스포머(IFT)는 ASK 변조된 변복조부(14)의 출력을 반송파신호 성분만 동조증폭한 뒤 전력선(L1.L2)을 통해 전원모듈로 전송한다. 중계트랜스포머(IFT)의 2차측코일에 접속된 콘텐서(C2)는 전원 전압 주파수(60 또는 120Hz) 신호를 제거하는 한편 반송파주파수를 전력선(L1,L2)로 송출한다. 그리고 중계트랜스포머(IFT)의 1차측코일에 접속된 콘텐서(C1)은 트랜스포머(IFT)의 2차측코일과 함께 반송파 주수 대역에 맞게 필터링주파수를 설정한다. 양방향 전송일 경우 중계트랜스포머(IFT)는 전원모듈로부터 전력선(L1,L2)을 통해 인입되는 변조된 신호를 필터링하여 변복조부(14)에 공급하며, 이때 변복조부(14)는 상기 중계트랜스포머(IFT)로부터 인입되는 신호를 복조하여 복조된 데이터를 마이콤(10)로 공급한다.At this time, the relay transformer ITF tunes and outputs only the carrier signal component of the ASK-modulated modulator 14 and transmits it to the power module through the power line L1.L2. The capacitor C2 connected to the secondary side coil of the relay transformer IFT removes the power supply voltage frequency (60 or 120 Hz) signal and transmits the carrier frequency to the power lines L1 and L2. The capacitor C1 connected to the primary side coil of the relay transformer IFT sets the filtering frequency according to the carrier frequency band together with the secondary side coil of the transformer IFT. In the case of bidirectional transmission, the relay transformer ITF filters the modulated signal inputted through the power lines L1 and L2 from the power module and supplies the modulated signal to the demodulator 14, wherein the modulator 14 outputs the relay transformer ITF. The demodulated signal is demodulated, and the demodulated data is supplied to the microcomputer 10.

그러면 마이콤(10)은 변복조부(14)로부터 이입된 데이터에 의해 적외선 발광다이오드(PD2)를 제어하여 적외선 수신완료신호를 원격송신기(11)로 송출한다. 이때 상기 적외선 발광다이오드(PD2)로부터 송촐된 적외선 수신완료신호에 의해 송출된 제어명령이 제대로 전달되었음을 표시하여 운용자에게 알려준다.Then, the microcomputer 10 controls the infrared light emitting diode PD2 by the data imported from the modulation and demodulation unit 14 to transmit the infrared reception completion signal to the remote transmitter 11. At this time, the control command sent by the infrared reception completion signal transmitted from the infrared light emitting diode PD2 is indicated to be properly transmitted to inform the operator.

상기 동기검출부(13)은 다음과 같이 구성된다.The synchronization detector 13 is configured as follows.

And rectification smoothing means comprising a diode ZD, a capacitor C3, and a resistor R1. In FIG. 1, a public telephone line may be used instead of the power lines L1 and L2 as a transmission medium.

상술한 바와 같이 본 발명은 양기능을 수행하게 함으로 편리성과 제어범위를 향상할 수 있는 이점이 있다.As described above, the present invention has an advantage of improving convenience and control range by performing both functions.
