본 고안은 퍼스널 컴퓨터등의 기기에 있어서, 데이타무선 수신회로에 관한 것으로, 특히 리모콘드의 원격제어장치를 사용하여 사용자가 필요에 따라 데이타를 무선으로 입력시킬 수 있도록 하여 공장 및 사무자동화에 효율적으로 활용할 수 있도록 한 데이타 무선 수신회로에 관한 것이다.The present invention relates to a data wireless receiving circuit in a device such as a personal computer, and in particular, by using a remote control device of a remote control to allow a user to wirelessly input data as needed, so that it is effective for factory and office automation. The present invention relates to a data wireless receiving circuit which can be utilized.

종래의 퍼스널 컴퓨터의 키보드의 유선회로도는 제1도에 도시한 바와 같이 한정된 길이의 유선으로만 컴퓨터에 데이타를 전송 즉, 사용자가 키보드를 조작하여 키보드콘넥터(1)로부터 출력되는 데이타가 클럭신호(CKS)에 따라 직렬 데이타로 직렬/병렬변환기(STC1)의 데이타 입력단자(DI1)에 입력되어 병렬데이타로 변환된 후 데이타버스를 통해 입출력포트(2)에 전송되는바, 이는 버스콘트롤러의 제어를 받아 화면에 데이타가 디스플레이되거나 메모리에 저장되게 구성되었으므로 키보드 조작시 조작가능한 유선상의 일정거리로 제한되고, 또한, 사용자가 필요에따라 일정거리에서 키보드를 조작해야될 경우에는 그에 따른 부가적인 무선 수신회로의 구성이 없었으므로 효율적인 업무처리를 하는데 어려움이 뒤따르게 되고, 공장 및 가정, 사무자동화 추세에 뒤따르지 못하는 등의 결함이 있었다.In the wired circuit diagram of the keyboard of a conventional personal computer, as shown in FIG. 1, data is transmitted to the computer only by a wire of a limited length, that is, data output from the keyboard connector 1 by a user operating the keyboard is a clock signal ( According to CKS), the serial data is input to the data input terminal DI 1 of the serial / parallel converter STC 1 , converted into parallel data, and then transmitted to the input / output port 2 through the data bus. It is configured to display data on the screen under control or to store it in memory, so it is limited to a certain distance on a wired line that can be operated when the keyboard is operated. Also, when a user needs to operate the keyboard at a certain distance as required, additional wireless is required. Since there is no configuration of receiving circuit, it is difficult to carry out efficient work processing, factory, home, office automation There were flaws such as not being followed in years.

본 고안은 이와같은 종래의 결함을 감안하여, 사용자가 필요에 따라 리모콘으로 데이타를 입력시킬 수 있도록 간단한 무선 수신회로의 구성을 안출한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made in consideration of such a conventional defect, and devised a configuration of a simple wireless receiving circuit so that a user can input data to the remote control as needed, described in detail by the accompanying drawings as follows.

제2도는 본 고안의 데이타신호 무선 수신회로도로서, 이에 도시한 바와같이 전원단자(VCC1)를 저항(R1) 및 유무선 표시용 발광다이오드(LED1)를 통해 키보드콘넥터(1)의 데이타신호출력단자(DT)에 접속함과 아울러 콘덴서(C1)를 통해 콘덴서(C2) 및 톤디코더(13)에 접속하고, 저항(R2), (R3) 및 콘덴서(C3), 포토센서다이오드(PSD1)로 된 데이타수신부(C6)를 통해 입력단자(FDI2)에 가변저항(VR1), (VR2) 및 저항(R6), 콘덴서(C7)로 된 시정수회로(12)가 접속된 톤디코더(13)의 데이타 입력단자(DI1)에 접속하여 구성한 것이다.2 is a circuit diagram of a data signal wireless receiver according to the present invention. As shown therein, a data signal of a keyboard connector 1 is connected to a power supply terminal VCC 1 through a resistor R 1 and a wired / wireless display LED 1 . connected to the output terminal (DT) also as well as through the capacitor (C 1) connected to the capacitor (C 2) and a tone decoder 13, and the resistance (R 2), (R 3) and capacitor (C 3), picture Time constant consisting of variable resistors (VR 1 ), (VR 2 ), resistor (R 6 ), and capacitor (C 7 ) at the input terminal (FDI 2 ) through the data receiver (C 6 ) of the sensor diode (PSD 1 ). The circuit 12 is connected to the data input terminal DI 1 of the tone decoder 13 to which the circuit 12 is connected.

이와같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured in this way in detail as follows.

키보드의 키를 조작하여 유선으로 데이타를 전송하는 과정은 상기에서 개략적으로 설명한 제1도와 동일하다.The process of transmitting data by wire by operating a key of the keyboard is the same as that of FIG.

즉, 전원단자(Vcc1), (Vcc2)에 전원이 인가되는 상태에서 리모콘(도면에 도시하지 않았음)으로 데이타를 전송할 경우에 키보드의 콘넥터(1)에서는 데이타신호가 출력되지 않게되므로 전원단자(Vcc1)의 전원이 저항(R1) 및 유무선 표시용발광다이오드(LED1) 인가되어 유무선표시용 발광다이오드(LED1)가 점등되고, 이에따라 사용자가 무선 즉, 리모콘의 키를 눌러 그 키신호가 데이타수신부(10)의 포토센서다이오드(PSD1)에 인가되면, 그 포토센서다이오드(PSD1)가 점등 및 소등됨에 따라 수신되는 데이타신호가 증폭기(11)를 통해 증폭되고, 그 증폭된 신호는 저항(R4) (R5) 및 콘덴서(C6)를 통해 톤디코더(13)의 데이타입력단자(DI1)에 입력되어 그의 입력단자(FDI2)에 입력되는 시정수회로(12)에 의해 검출되는 발전신호(OSD)의 발진주파수에 따라 디코딩되고, 그 디코딩신호는 입출력포트(2)로 출력되게 된다.That is, when data is transmitted to the remote controller (not shown) while the power is supplied to the power terminals Vcc 1 and Vcc 2 , the data signal is not output from the connector 1 of the keyboard. The power of the terminal Vcc 1 is applied to the resistor R 1 and the wired / wireless light emitting diode LED 1 so that the wired / wireless light emitting diode LED 1 is turned on. When the key signal is applied to the photosensor diode PSD 1 of the data receiver 10, the received data signal is amplified through the amplifier 11 as the photosensor diode PSD 1 is turned on and off, and the amplification thereof is performed. The received signal is input to the data input terminal DI 1 of the tone decoder 13 through the resistor R 4 (R 5 ) and the condenser C 6 and is input to the input terminal FDI 2 thereof . 12) is decoded according to the oscillation frequency of the power generation signal (OSD) detected by , The decoded signal is output to the output port (2).

이상에서 설명한 바와같이 기존의 퍼스널컴퓨터의 키보드콘넥터 데이타라인에 간단한 무선수신회로를 병렬로 접속시켜 사용자가 필요에따라 유선 또는 무선으로 데이타를 전송할 수 있게 함으로써, 사용자가 보다 더 편리하게 사용할 수 있음은 물론 공장 및 가정, 사무자동화추세에 따른 기대효과가 매우 크다.As described above, by connecting a simple wireless receiving circuit in parallel to the data line of the keyboard connector of the existing personal computer, the user can transmit data by wire or wireless as needed, so that the user can use it more conveniently. Of course, the expected effects of factory, home, and office automation trends are enormous.
