Description

Remote Control Device {Apparatus Of Remote Controlling}

본 발명은 영상기기와 같은 가전기기를 원격제어하는 장치에 관한 것으로, 특히 리모콘의 제어범위를 벗어나는 위치에 존재하는 원격제어장치에 관한 것이다.The present invention relates to a device for remotely controlling home appliances, such as a video device, and more particularly to a remote control device existing in a position outside the control range of the remote control.

일반적으로, 리모콘에서 생성된 적외선신호(이하 리모콘 제어신호라 함)는 벽과 같은 장애물을 통과할 수 없다. 이에 따라 장애물로 막혀있는 가전기기를 제어하려면 장애물을 통과할수 있는 전파를 이용한 고주파신호(이하 무선제어신호라 함)를 주고받는 무선송수신기가 필요하다. 도 1은 무선송수신기를 이용하여 리모콘의 제어범위를 벗어난 다른 가전기기를 제어하는 종래의 원격제어방법의 예를 보여주는 도면이다.In general, the infrared signal generated by the remote controller (hereinafter referred to as a remote controller control signal) cannot pass through an obstacle such as a wall. Accordingly, in order to control home appliances that are blocked by obstacles, wireless transmitters and receivers that transmit and receive high frequency signals (hereinafter referred to as wireless control signals) using radio waves that can pass through the obstacles are required. 1 is a view showing an example of a conventional remote control method for controlling other home appliances outside the control range of the remote control using a wireless transmitter and receiver.

도 1을 참조하면, 위성방송 수신시설이 갖추어진 가정의 한 예를 보여주고 있다. 위성방송수신기(12)가 거실(52)에 위치한 텔레비젼(19)에 연결되고, 또한 침실(50)에 설치된 텔레비젼(17)에도 연결되어 있다. 사용자가 거실(52)에서 위성방송을 시청하다가, 좀 더 편안한 시청을 위해 침실(50)로 이동하게 된다면 침실(50)과 거실(52)사이의 장애물로 인해, 사용자가 침실(50)에서 리모콘(16)으로써는 위성방송수신기(12)를 제어할 수 없게 된다. 이러한 문제를 해결하기위해, 종래에는 리모콘(16) 제어신호를 위성방송수신기(12)에 전송하기 위한 별도의 무선 송수신기(4,8)를 구비하고 있다.1 shows an example of a home equipped with a satellite broadcasting receiving facility. The satellite broadcast receiver 12 is connected to a television 19 located in the living room 52 and also to a television 17 installed in the bedroom 50. If the user watches satellite broadcasting in the living room 52 and moves to the bedroom 50 for more comfortable viewing, the user may be able to control the remote control in the bedroom 50 due to an obstacle between the bedroom 50 and the living room 52. At 16, the satellite broadcast receiver 12 cannot be controlled. In order to solve this problem, the conventional remote control 16 is provided with separate radio transceivers 4 and 8 for transmitting the control signal to the satellite broadcasting receiver 12.

침실(50)에 위치한 사용자가 거실(52)에 위치한 위성방송수신기(12)를 제어하여 침실(50)에서 위성방송을 시청하려면 리모콘(16)을 조작하여 위성방송수신기(12)를 제어하기 위한 리모콘제어신호(2)를 무선송신기(4)로 송신한다. 무선송신기(4)는 리모콘(16)으로부터 전송된 리모콘제어신호(2)에 응답하여 무선제어신호(6)를 거실(52)에 있는 무선수신기(8)로 송신한다. 거실(52)에 설치되어 있는 무선수신기(8)는 무선송신기(4)로 부터의 무선제어신호(6)에 응답하여, 위성방송수신기(12)를 제어하기위한 리모콘제어신호(10)를 생성한다. 생성된 리모콘제어신호(10)는 위성방송수신기(12)로 송신된다. 위성방송수신기(12)는 무선수신기(8)로부터의 리모콘제어신호(10)에 응답하여 구동되기 시작한다. 구동된 위성방송수신기(12)는 영상음성신호선(14)을 통해 위성으로부터 수신된 위성방송신호를 침실(50)에 설치된 텔레비젼(17)쪽으로 송신한다.The user located in the bedroom 50 controls the satellite broadcast receiver 12 located in the living room 52 to watch satellite broadcasts in the bedroom 50 by manipulating the remote controller 16 to control the satellite broadcast receiver 12. The remote control control signal 2 is transmitted to the radio transmitter 4. The radio transmitter 4 transmits the radio control signal 6 to the radio receiver 8 in the living room 52 in response to the remote controller control signal 2 transmitted from the remote controller 16. The radio receiver 8 installed in the living room 52 generates a remote control control signal 10 for controlling the satellite broadcast receiver 12 in response to the radio control signal 6 from the radio transmitter 4. do. The generated remote control signal 10 is transmitted to the satellite broadcast receiver 12. The satellite broadcast receiver 12 starts to be driven in response to the remote control control signal 10 from the radio receiver 8. The driven satellite broadcast receiver 12 transmits the satellite broadcast signal received from the satellite via the video audio signal line 14 toward the television 17 installed in the bedroom 50.

이와 같은 원격제어에 있어서는 위성방송수신기 설치 외에 전술한 바와 같이 무선송신기 및 무선수신기가 필요하게 된다. 이에 따라, 무선송신기 및 무선수신기 구입에 따른 많은 추가비용이 발생하게 된다. 또한 무선송신기 및 무선수신기에 의해 발생된 전파가 옆집에 설치되어 있는 위성방송수신기에까지 영향을 줄 수 있다. 아울러 다른 원격지에서 위성방송을 수신하려면 설치가 복잡한 무선송신기 및 무선수신기를 다시 설치해야하는 문제점이 있다.In such remote control, a radio transmitter and a radio receiver are required as described above in addition to the satellite broadcast receiver. Accordingly, many additional costs are incurred due to the purchase of the wireless transmitter and the wireless receiver. In addition, the radio waves generated by the radio transmitter and the radio receiver may affect the satellite broadcast receiver installed next door. In addition, in order to receive satellite broadcasts from other remote locations, there is a problem in that the radio transmitter and the radio receiver are complicated to install.

따라서, 본 발명의 목적은 리모콘의 제어범위를 벗어나는 위치에 존재하는 가전기기의 원격제어장치를 제공하는데 있다.Accordingly, an object of the present invention is to provide a remote control device for a home appliance that is located at a position outside the control range of the remote controller.

상기 목적을 달성하기 위하여, 본 발명에 따른 원격제어장치는 제 1 및 제 2 가전기기를 제어하기 위한 제어신호를 발생하는 원격제어송신기와, 제 1 가전기기 내부에 설치되어 원격제어송신기로부터의 원격제어신호를 수신하는 원격제어신호수신부와, 원격제어신호수신부로부터의 제어신호에 응답하여 제 2 가전기기를 제어하는 고주파신호형태의 유선제어신호를 생성하여 유선을 통해 출력하는 유선제어신호 발생부를 구비하는 송신세트와, 제 2 가전기기 내부에 설치되어 유선제어신호를 수신하는 유선제어신호수신부와, 원격제어신호를 수신하는 제2 원격제어신호수신부와, 유선제어신호수신부로부터의 유선제어신호에 따라 제 2 가전기기의 동작을 제어하는 제어부를 구비하는 수신세트를 구비한다.In order to achieve the above object, the remote control apparatus according to the present invention is a remote control transmitter for generating a control signal for controlling the first and second home appliances, and a remote control transmitter installed inside the first home appliance Remote control signal receiving unit for receiving a control signal and a wired control signal generator for generating a high-frequency signal type wired control signal for controlling the second home appliance in response to a control signal from the remote control signal receiving unit to output through a wire A wired control signal receiver, a wired control signal receiver for receiving a wired control signal, a second remote control signal receiver for receiving a remote control signal, and a wired control signal from a wired control signal receiver. And a receiving set having a control unit for controlling the operation of the second household appliance.

상기 목적 외에 본 발명의 다른 목적 및 특징들은 첨부도면을 참조한 실시예에 대한 설명을 통하여 명백하게 드러나게 될 것이다.Other objects and features of the present invention in addition to the above objects will become apparent from the description of the embodiments with reference to the accompanying drawings.

이하, 도 2 를 참조하여 본 발명의 바람직한 실시예에 대하여 설명하기로 한다. 도 2를 참조하면, 음성신호선(38)에 위성방송수신명령을 출력하기 위한 텔레비젼구동부(20)와 음성신호선(38)으로부터 위성방송수신명령을 입력받아 수신된 위성방송을 텔레비젼으로 송신하는 위성방송수신부(30)를 구비하는 본 발명의 실시예에 따른 원격제어장치가 도시되어 있다.Hereinafter, a preferred embodiment of the present invention will be described with reference to FIG. 2. Referring to FIG. 2, a satellite broadcast receiving a satellite broadcast receiving command from a television driver 20 and an audio signal line 38 for outputting a satellite broadcast receiving command to a voice signal line 38, and transmitting the received satellite broadcast to a television. A remote control device according to an embodiment of the present invention having a receiver 30 is shown.

리모콘(62)에는 초기값으로 텔레비젼구동부(20)를 제어하고, 한번누르면 음성신호선(38)을 통해 텔레비젼구동부(20)에 연결된 위성방송수신부(30)를 제어할수 있는 키, 즉 텔레비젼/위성방송 토글키가 마련된다. 먼저, 텔레비젼구동부(20)의 리모콘수신부(22)에 리모콘(62)으로부터 리모콘 제어신호가 입력되면, 리모콘수신부(22)는 하이논리를 가지는 제어신호를 마이크로컴퓨터(24)(Micor Computer ; 이하 마이콤이라 함)에 인가한다. 이때, 마이콤(24)은 리모콘수신부(22)로부터 입력된 제어신호가 위성방송수신부(30) 제어모드라 판단되면 출력포트(60)를 통해 하이논리 신호를 출력하고, 이 하이논리 신호는 AND게이트(28)의 입력단자로 입력된다. 이와 동시에 마이콤(24)으로부터의 하이논리 신호는 구형파고주파발진기(26)에 입력되어 구형파고주파발진기(26)를 구동시킨다. 이때 AND게이트(28)는 마이콤(24)의 하이논리출력을 입력받는 상태가 된다. 즉, 마이콤(24)의 출력이 하이논리일 때, AND게이트(28)의 출력이 하이논리가 된다. 다시말하면, 마이콤(24)이 하이논리일 때, 구형파고주파발진기(26)의 출력값이 고역통과필터(32)에 공급된다. 한편, 마이콤(24)은 리모콘수신부(22)로부터 입력된 제어신호가 위성방송수신부(30) 제어모드가 아니라고 판단되면, 기타제어회로(25)를 제어하기 위한 제어신호를 생성한다. 즉, 마이콤(24)은 리모콘수신부(22)의 제어신호의 입력에 따라 동작이 결정된다. 한편, AND게이트(28)의 출력신호는 구형파고주파발진기(26)에서 입력된 최대 50㎑의 주파수신호에 리모콘제어신호가 실린 디지털신호가 되며, 이 디지털신호는 고역통과필터(32)에 입력된다. 고역통과필터(32)는 음성신호대역(20㎑)에 대해서는 큰 임피던스 값을 가지며, AND게이트(28)의 디지털출력신호(50㎑)에 대해서는 작은 임피던스값을 갖는다. 즉, 고역통과필터(32)는 위성방송수신부(30)로부터 음성신호선(38)을 통해 공급되는 음성신호대역의 주파수를 차단하면서 AND게이트(28)의 고주파 디지털 출력신호는 통과시킨다. 고역통과필터(32)에서 출력된 고주파 신호는 버퍼(34)와 음성신호선(38)에 입력된다. 버퍼(34)에 입력된 고주파신호는 버퍼(34)에 연결된 고역제거필터(36)에 의해 제거된다. 즉, 고역제거필터(36)는 버퍼(34)에 입력된 고주파신호는 제거하면서, 위성방송수신부(30)로부터 입력된 음성신호는 통과시킨다. 음성출력회로(35)는 고역제거필터(36)를 통해 입력된 음성신호를 스피커(37)로 출력시킨다. 스피커(37)는 음성출력회로(35)로부터 입력받은 음성신호를 증폭시켜 출력시킨다. 한편, 고역통과필터(32)에서 음성신호선(38)에 입력된 고주파신호는 위성방송수신부(30)의 버퍼(42)에 입력됨과 동시에 고역제거필터(43)에 입력된다. 고역제거필터(43)에 입력된 고주파신호는 고역제거필터(43)에 의해 제거된다. 즉, 고역제거필터(43)는 음성신호선(38)으로부터 입력된 고주파신호는 제거하면서, 음성검파부(59)로부터 입력된 음성신호는 통과시킨다. 버퍼(42)에 입력된 고주파신호는 버퍼(42)를 통과후, 대역통과필터(44)에 의해 대역필터링 된 다음 적분기(46)로 입력된다. 적분기(46)는 입력된 고주파신호를 적분하여, 리모콘제어신호를 복구해 낸다. 적분기(46)에서 출력된 리모콘제어신호는 히스테리시스 특성을 갖는 인버터(48)에 의해 파형이 정형되어 오어게이트(54)(OR GATE : 이후 OR 게이트라 함)에 입력된다. 인버터(48)로부터 OR게이트(54)에 입력된 리모콘제어신호는 OR게이트(54)의 논리합 연산에 의해 마이콤(56)으로 출력된다. OR게이트(54)의 다른 한 입력단은 자체 리모콘수신부(58)의 출력신호를 공급받는다. 마이콤(56)은 OR게이트(54)에서 입력된 제어신호에 의해 기타제어회로(64)에 포함되어 있는 위성방송수신부, 위성방송출력부 및 이들을 제어하는 회로부등을 제어하여 영상과 음성신호를 텔레비젼구동부(20)로 출력시키게 된다. 음성검파부(59)는 마이콤에서 입력된 음성신호를 추출하여 고역제거필터(43)로 출력시킨다. 이와 동시에, 위성방송신호에 포함된 영상신호는 마이콤(56)의 제어에 의해 도시하지 않은 영상신호선을 통하여 텔레비젼으로 출력된다. 한편, 사용자가 위성방송수신부(30)를 직접 리모콘 제어할 때에는, 위성방송수신부(30)의 리모콘수신부(58)가 리모콘(62)으로부터의 리모콘제어신호를 입력받아 OR게이트(54)로 제어신호를 출력한다. 리모콘수신부(58)로부터 OR게이트(54)에 입력된 제어신호는 OR게이트(54)의 논리합연산에 의해 마이콤(56)으로 출력된다. 전술한 바와 같이, 마이콤(56)은 OR게이트(54)의 제어신호를 입력받아 위성방송수신부(30)의 모든 제어회로를 제어한다.The remote controller 62 controls the TV driver 20 at an initial value, and when pressed once, a key capable of controlling the satellite broadcast receiver 30 connected to the TV driver 20 through the audio signal line 38, that is, the TV / satellite broadcast. A toggle key is provided. First, when a remote controller control signal is input from the remote controller 62 to the remote controller receiver 22 of the television driver 20, the remote controller 22 transmits a control signal having high logic to the microcomputer 24 (Micor Computer; Is referred to). At this time, the microcomputer 24 outputs a high logic signal through the output port 60 when it is determined that the control signal input from the remote control receiver 22 is the control mode of the satellite broadcast receiver 30, and the high logic signal is an AND gate. Input terminal (28) is input. At the same time, the high logic signal from the microcomputer 24 is input to the square wave frequency oscillator 26 to drive the square wave frequency oscillator 26. At this time, the AND gate 28 is in a state of receiving the high logic output of the microcomputer 24. That is, when the output of the microcomputer 24 is high logic, the output of the AND gate 28 becomes high logic. In other words, when the microcomputer 24 is in high logic, the output value of the square wave high frequency oscillator 26 is supplied to the high pass filter 32. On the other hand, if it is determined that the control signal input from the remote control receiver 22 is not the satellite broadcast receiver 30 control mode, the microcomputer 24 generates a control signal for controlling the other control circuit 25. That is, the operation of the microcomputer 24 is determined according to the input of the control signal of the remote control receiver 22. On the other hand, the output signal of the AND gate 28 is a digital signal loaded with a remote control control signal to a frequency signal of up to 50 kHz input from the square wave frequency oscillator 26, which is input to the high pass filter 32. . The high pass filter 32 has a large impedance value for the audio signal band 20 kHz and a small impedance value for the digital output signal 50 kHz of the AND gate 28. That is, the high pass filter 32 cuts the frequency of the voice signal band supplied from the satellite broadcasting receiver 30 through the voice signal line 38 and passes the high frequency digital output signal of the AND gate 28. The high frequency signal output from the high pass filter 32 is input to the buffer 34 and the audio signal line 38. The high frequency signal input to the buffer 34 is removed by the high pass filter 36 connected to the buffer 34. That is, the high pass filter 36 removes the high frequency signal input to the buffer 34 while passing the audio signal input from the satellite broadcasting receiver 30. The voice output circuit 35 outputs the voice signal input through the high pass filter 36 to the speaker 37. The speaker 37 amplifies and outputs the voice signal received from the voice output circuit 35. Meanwhile, the high frequency signal input to the voice signal line 38 by the high pass filter 32 is input to the buffer 42 of the satellite broadcasting receiver 30 and to the high pass rejection filter 43. The high frequency signal input to the high pass removing filter 43 is removed by the high pass removing filter 43. That is, the high pass filter 43 removes the high frequency signal input from the voice signal line 38 while passing the voice signal input from the voice detector 59. The high frequency signal input to the buffer 42 passes through the buffer 42, is band filtered by the band pass filter 44, and then input to the integrator 46. The integrator 46 integrates the input high frequency signal to recover the remote control control signal. The remote control control signal output from the integrator 46 is inputted to the or gate 54 (OR GATE: later OR gate) by shaping the waveform by the inverter 48 having hysteresis characteristics. The remote control control signal input from the inverter 48 to the OR gate 54 is output to the microcomputer 56 by the OR operation of the OR gate 54. The other input of the OR gate 54 is supplied with the output signal of its own remote control receiver 58. The microcomputer 56 controls the satellite broadcasting receiver, the satellite broadcasting output unit, and the circuit unit controlling them by the control signal inputted from the OR gate 54 to display the video and audio signals. Output to the driver 20. The voice detector 59 extracts the voice signal input from the microcomputer and outputs it to the high pass filter 43. At the same time, the video signal contained in the satellite broadcast signal is output to the television via the video signal line (not shown) under the control of the microcomputer 56. On the other hand, when the user directly controls the satellite broadcast receiver 30, the remote controller receiver 58 of the satellite broadcast receiver 30 receives a remote controller control signal from the remote controller 62 and sends a control signal to the OR gate 54. Outputs The control signal input to the OR gate 54 from the remote control receiver 58 is output to the microcomputer 56 by the logical operation of the OR gate 54. As described above, the microcomputer 56 receives the control signal of the OR gate 54 and controls all the control circuits of the satellite broadcasting receiver 30.

결과적으로, 위성방송수신부(30)는 OR게이트(54)에 입력되는 텔레비젼구동부의 출력신호 또는 리모콘 출력신호에 응답하여 수신된 위성방송신호를 텔레비젼구동부에 공급한다.As a result, the satellite broadcast receiver 30 supplies the received satellite broadcast signal to the television driver in response to the output signal of the television driver or the remote controller output signal input to the OR gate 54.

상술한 바와 같이, 본 발명에 따른 원격제어장치에 의하면, 무선송신기 및 무선수신기 없이도 텔레비젼을 제어하는 하나의 리모콘 조작으로 다른 곳에 위치한 다른 가전기기를 유선으로 제어할 수 있게 된다. 따라서 별도의 무선송신기 및 무선수신기를 설치할 필요가 없고, 이에 따른 설치비 및 설치 공간이 필요없다. 또한, 유선으로 연결된 신호선에 디지털신호를 송신하기 때문에 노이즈에 강하고, 무선신호에 의한 방해가 없다는 장점이 있다.As described above, according to the remote control apparatus according to the present invention, it is possible to control other household appliances located in another place by wire operation with one remote control to control a television without a radio transmitter and a radio receiver. Therefore, there is no need to install a separate wireless transmitter and a wireless receiver, there is no need for installation costs and installation space. In addition, since a digital signal is transmitted to a signal line connected by wire, it is strong in noise and has no advantage of interference by a wireless signal.
