본 고안은 리모콘 송신장치와 같은 무선 키이 보오드(Key Board)에서 단순한 온, 오프가 아닌 펄스성 순간신호를 송출함에 있어서 보다 원거리에서 외부 잡은신호에 대한 저항이 큰 보다 확실한 신호를 수광소자에 전달할 수 있게한 무선 키이 보오드의 배전압회로에 관한 것이다.The present invention can transmit a more reliable signal to a light receiving element having a greater resistance to externally caught signals at a far distance when transmitting a pulsed instantaneous signal rather than a simple on / off signal from a wireless key board such as a remote control transmitter. The present invention relates to a double voltage circuit of a board.
종래의 리모콘 송신장치와 같은 무선 키이 보오드에 있어서는 제 1 도에 도시한 바와같이 무선 키이 보오드(1)의 키이를 누름에 따라 그의 집적소자(2)에서 펄스신호가 출력되어 트랜지스터(Q)를 직접 온 시킴으로써 트랜지스터(Q)의 콜렉터에 접속된 발광다이오드(LED1)와 적외선다이오드(LED2,LED3)가 점등되어 송신신호를 송출하게 되어 있으나, 이러한 종래의 장치는 건전지(B1)의 전원이 발광다이오드(LED1) 및 적외선다이오드(LED2,LED3)를 직접 통하여 흐르게 되므로 건전지(B1)의 전원이상의 전류를 흐르게 할 수 없었고, 이에따라 건전지의 전원만 가지고는 원하는 목적에 확실한 펄스성 신호를 인가하는 것이 불충분하여 수광부에서 오동작돌 염려가 있었고, 또한 충분한 원격제어를 할 수 없는 결점이 있었다.In a wireless key board, such as a conventional remote control transmitter, as shown in FIG. 1, as the key of the wireless key board 1 is pressed, a pulse signal is output from the integrated element 2 thereof to directly switch the transistor Q. By turning on, the light emitting diodes LED 1 and the infrared diodes LED 2 and LED 3 connected to the collector of the transistor Q are turned on to transmit a transmission signal. However, such a conventional device is a power source of the battery B 1 . Since the light emitting diodes (LED 1 ) and infrared diodes (LED 2 , LED 3 ) flow directly through, the current beyond the power of the battery (B 1 ) could not be flowed. There was a risk of malfunction in the light-receiving section due to insufficient signal application, and also a defect in not being able to perform sufficient remote control.
본 고안은 이러한 점을 감안하여, 배전압효과를 가지는 간단한 구조의 회로를 건전지와 적외선 다이오드 사이에 구성시킴으로써 키이 보오드에 연결된 집적소자에서 출력신호가 출력될때 적외선 다이오드에 건전지의 전원이상의 전류가 흐르게하여 보다 확실한 송신신호가 출력되게 안출한 것으로, 이를 첨부된 도면에 의하여 보다 상세히 설명하면 다음과 같다.In view of the above, the present invention consists of a simple circuit having a double voltage effect between the battery and the infrared diode, so that when the output signal is output from the integrated device connected to the key board, the current of the battery power exceeds the infrared diode. A more reliable transmission signal is intended to be output, which will be described in more detail with reference to the accompanying drawings.
제 2 도는 본 고안의 상세회로도로서, 이에 도시한 바와 같이, 키이보오드(1)와 건전지(B1)에 연결된 신호 발생용 집적소자(2)의 출력측을 전류제한용 저항(R1)을 통해 제너다이오드(ZD1) 및 트랜지스터(Q2)의 베이스에 접속하여 그 접속점을 분류용 저항(R2)을 통해 접지저항(R3) 및 그의 에미터에 접속하고, 건전지(B1)에 에미터를 접속한 트랜지스터(Q1)의 베이스와 콜렉터를 트랜지스터(Q2)의 콜렉터와 접지저항(R4)에 각각 접속하여, 그 트랜지스터(Q1)의 에미터와 콜렉터를 다이오드(D1) 및 콘덴서(C1)에 공통접속한 후 그 접속점을 발광다이오드(LED1) 및 적외선다이오드(LED2-LED4)를 각각 통하여 에미터플로워로 접속된 트랜지스터(Q3),(Q4)의 콜렉터에 접속하고, 그 트랜지스터(Q3)의 베이스를 저항(R5)을 통하여 트랜지스터(Q2)의 에미터에 접속하여 구성한 것으로, 이와같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.FIG. 2 is a detailed circuit diagram of the present invention, and as shown therein, the output side of the signal generating integrated device 2 connected to the key board 1 and the battery B 1 is connected to the current limiting resistor R 1 . It is connected to the base of the zener diode ZD 1 and the transistor Q 2 , and its connection point is connected to the grounding resistor R 3 and its emitter through the dividing resistor R 2 , and the battery B 1 The base and the collector of the transistor Q 1 connected to the emitter are connected to the collector and the ground resistor R 4 of the transistor Q 2 , respectively, and the emitter and the collector of the transistor Q 1 are connected to the diode D 1 . And the connection points of the transistors Q 3 and Q 4 connected to the emitter follower through the common connection to the capacitor C 1 and then through the light emitting diodes LED 1 and the infrared diodes LED 2 to LED 4 , respectively. connected to the collector and the emitter of the transistor (Q 3) transistor (Q 2) to the base through a resistor (R 5) of the That is configured to connect, in this way will be described in detail the operational effect of the present design is configured as follows.
키이 보오드(1)를 눌러 신호발생용 집적소자(2)에서 펄스신호가 출력되면, 이 펄스신호는 저항(R1)을 통하여 제너다이오드(ZD1)에 전위를 갖게하므로 트랜지스터(Q2)의 베이스에 바이어스 전압이 인가되어 트랜지스터(Q2)를 온 시키고 이에따라 그의 콜렉터 전류가 급증하여 트랜지스터(Q1)의 베이스에 바이어스 전압이 인가되므로 트랜지스터(Q1)는 온 된다. 그런데, 신호발생용 집적소자(2)에서 펄스신호가 출력되지 이전에 건전지(B1)의 전원이 다이오드(D1)를 통하여 콘덴서(C2)에 이미 충전되게 된다. 따라서, 상기와 같이 트랜지스터(Q1)가 온되면 건전지(B1), 콘덴서(C2)가 직렬로 접속되어 건전지(B1)의 전원에 콘덴서(C2)의 충전전압이 합해져 발광다이오드(LED1) 및 적외선다이오드(LED2-LED4)의 에노드에 가해진다. 또한, 이때 트랜지스터(Q2)의 에미터 출력전압은 저항(R5)을 통하여 트랜지스터(Q3),(Q4)를 온시키므로 발광다이오드(LED1)와 적외선다이오드(LED2-LED4)는 구동 발광하게 된다.When the key boards (1) for pressing the integrated for signal generation element 2, the pulse signal is output, a pulse signal, so have the potential to the Zener diode (ZD 1) via the resistor (R 1) of the transistor (Q 2) is applied with a bias voltage to the base and turns on the transistor (Q 2) yiettara since the bias voltage applied to its collector current is a sudden increase in the base of the transistor (Q 1) is a transistor (Q 1) is turned on. However, before the pulse signal is output from the signal generation integrated device 2, the power of the battery B 1 is already charged in the capacitor C 2 through the diode D 1 . Accordingly, as described above, when the transistor Q 1 is turned on, the battery B 1 and the capacitor C 2 are connected in series, and the charging voltage of the capacitor C 2 is added to the power source of the battery B 1 so that the light emitting diode ( LED 1 ) and infrared diodes (LED 2- LED 4 ) are applied to the anode. In this case, the emitter output voltage of the transistor Q 2 turns on the transistors Q 3 and Q 4 through the resistor R 5 , so that the light emitting diodes LED 1 and the infrared diodes LED 2 -LED 4 . Will drive light emission.
여기에서, 트랜지스터(Q1)가 지속적으로 온상태를 유지하면 콘덴서(C2)의 방전특성에 따라 발광다이오드(LED1) 및 적외선다이오드(LED2-LED4)에 인가되는 전압이 저하되지만, 신호발생용 집적소자(2)에서 출력되는 신호는 타임-듀티(Time-Duty)를 가지는 펄스신호이고, 또한 회로적으로 동일한 온, 오프시간일지라도 충전시정수가 방전시정수보다 훨씬 빠르게 설정되어 있으므로 발광다이오드(LED1) 및 적외선다이오드(LED2-LED4)에 인가되는 실제의 전압은 저하됨이 없이 건전지(B1)의 전원과 콘덴서(C2)의 충전전압 합이 인가되게 된다.Here, when the transistor Q 1 is continuously kept on, the voltage applied to the light emitting diodes LED 1 and the infrared diodes LED 2 to LED 4 decreases depending on the discharge characteristics of the capacitor C 2 . The signal output from the signal generating integrated device 2 is a pulse signal having a time-duty, and the light emission time is set much faster than the discharge time constant even though the circuits have the same on / off time. The actual voltages applied to the diodes LED 1 and the infrared diodes LED 2 to LED 4 are applied with the sum of the charging voltages of the power source of the battery B 1 and the capacitor C 2 without being lowered.
이상에서와 같이 동작되는 본 고안은 같은 건전지를, 사용하면서도 발광다이오드 및 적외선다이오드를 구동시키는 전압은 실제적으로 건전지의 전압보다 2배 가까이 증가되므로 복잡한 신호전달을 필요로하는 키이 보오드에서 보다 확실한 신호를 전달할 수 있고, 보다 원격의 조정을 기할 수 있게되는 이점이 있다.The present invention operating as described above, while using the same battery, the voltage driving the light emitting diodes and the infrared diodes actually increases nearly twice as much as the voltage of the battery, so it is possible to obtain a more reliable signal in a key board requiring complex signal transmission. There is an advantage to be able to deliver, and more remote control.
