본 고안은 경보스위치 장치에 관한 것으로, 특히 적외선에 의한 감지 스위칭장치에 관한 것이다.The present invention relates to an alarm switch device, and more particularly to a sensing switching device by infrared rays.

종래에도 적외선을 이용한 경보장치가 알려져 있으나 회로도 콤팩트화 할수 없어서 제조원가를 높여주는 원인이 되었던바, 본 고안은 이와같은 종래의 불편함을 감안하여 회로가 간단하면서도 동작이 정확하며 저렴한 값으로 공급할수 있도록 개량한 것으로, 이하 본고안을 첨부된 도면에 따라 상술한다.In the past, an alarm system using infrared rays is known, but the circuit could not be made compact, which caused the manufacturing cost to increase. The present invention is designed to provide a simple, accurate and inexpensive operation of the circuit in consideration of such inconvenience. The present invention will be described in detail below with reference to the accompanying drawings.

첨부된 도면은 본고안을 설명하기 위한 전기적 회로도로, 저항(R2)과 제너다이오드(ZD)및 콘덴서(C1,C2)로 공지의 정전압회로가 구성되어 이하 설명하는 각 회로의 전원을 정전압으로 공급하도록 되었으며, 저항(R3,R4)과 콘덴서(C3,C4)에 의해 발진회로(OSC)가 구성되어 그 출력신호는 저항(R13)을 통해 발광다이오드(LED1,LED2)및 저항(R14)을 직렬연결하여 에미터접지된 트랜지스터(TR1)의 베이스에 연결되고 콜렉터는 상기한 정전압전원에 연결하여 적외선 발광회로가 구성되어 있다. 한편 저항(R6)으로 접지된 포토트랜지스터(TR)의 콜렉터는 콘덴서(C5)를 통해 저항(R7)으로 기준전압단자에 기준전압이 가해진 OP암프(OP1)의 비교입력단자에 연결되었으며, 정전압입력단자에는 다이오드(D1)로 접지됨과 동시에 저항(R7)에 의해 정해진 전압이 인가되도록 되어 있다.The accompanying drawings are electrical circuit diagrams for explaining the present invention, and a known constant voltage circuit is composed of a resistor (R 2 ), a zener diode (ZD), and a capacitor (C 1 , C 2 ) to supply power to each circuit described below. was to provide a constant voltage, a resistance (R 3, R 4) and the condenser light emitting diode through the oscillator circuit resistance (R 13) and its output signal (OSC) is constituted by a (C 3, C 4) ( LED 1, The LED 2 ) and the resistor R 14 are connected in series and connected to the base of the emitter grounded transistor TR 1 , and the collector is connected to the constant voltage power source. On the other hand, the collector of the phototransistor TR grounded with the resistor R 6 is connected to the comparison input terminal of the OP amp OP 1 in which the reference voltage is applied to the reference voltage terminal with the resistor R 7 through the capacitor C 5 . At the same time, the voltage defined by the resistor R 7 is applied to the constant voltage input terminal while being grounded by the diode D 1 .

또, 상기한 OP암프(OP1)의 출력측은 콘덴서(C6)를 통해 고정입력단자가 접지된 OP암프(OP1)의 비교입력단자에 연결됨과 동시에 OP암프(OP1)의 출력은 저항(R8)과 콘덴서(C9)를 병렬로 하여 비교입력단자에 휘드백회로가 구성되어 있다.In addition, the output side of the OP amp OP 1 is connected to the comparison input terminal of the grounded OP amp OP 1 via a capacitor C 6 and the output of the OP amp OP 1 is a resistor. A feedback circuit is formed at the comparison input terminal with (R 8 ) and capacitor (C 9 ) in parallel.

또, 상기한 OP암프(OP2)의 출력은 다이오드(D2)와 저항(R10)을 통해 멀티바이브레이터지연회로(MV)의 입력측에 연결됨과 동시 콘덴서(C7)로 접지되고 또 저항(R9)을 통해 비교입력단자에 휘드백되었으며 상기한 멀티바이브레이터지연회로의 출력신호가 저항(R12)을 통해 에미터접지된 트랜지스터(TR2)에 베이스에 연결되고 전원 B+콜렉터사이에는 릴레이(RY)가 연결하여서 된 것이다.In addition, the output of the OP amp OP 2 is connected to the input side of the multivibrator delay circuit MV through the diode D 2 and the resistor R 10 , and is grounded by the condenser C 7 . R 9) a was bent feedback to the comparison input terminal connected to the base to the emitter grounded transistor (TR 2) through the output signal of the above-mentioned multivibrator delay circuit resistance (R 12) over and between the power supply B + collector, the relay ( RY) is a concatenation.

도면중 미설명부호 C7및 C8은 콘덴서이며, R1은 저항, D3은 다이오드이다.In the drawings, reference numerals C 7 and C 8 are capacitors, R 1 is a resistor, and D 3 is a diode.

따라서 발광다이오드(LED1,LED2)는 하나의 적외선 발광체가 되며 포토트랜지스터(TR)는 상기한 발광다이오드(LED1,LED2)의 적외선을 수신하도록 됨은 공지와 같은 것이다.Therefore, it is known that the light emitting diodes LED 1 and LED 2 become one infrared light emitter and the phototransistor TR is configured to receive the infrared rays of the light emitting diodes LED 1 and LED 2 .

상기와 같은 구성으로 되는 것이므로 전원입력측(IN)에 직류전원을 연결시키는 경우 콘덴서(C3)와 저항(R3,R4)의 시정수에 의해 발진기회로(OSC)는 일정한 주파수신호가 트랜지스터(TR1)의 베이스를 트리거하게 되고, 이에 따라 트랜지스터(TR1)의 에미터-콜렉터 사이는 ON되므로 전원 B+은 저항(R14)으로 접지된 발광다이오드(LED1,LED2)를 발광시켜 주게 되고, 또, 이와같은 광선을 수광하는 포토트랜지스터(TR)는 ON되어 접지된 저항(R6)을 통해 접지에 도통되어 콘덴서(C5)를 충전하지 못하는 연산증폭기인 OP암프(OP1)의 비교입력단자에는 아무런 신호가 없게되고 따라서 OP암프(OP1)의 출력에도 아무런 신호가 없게된다.In this case, when the DC power source is connected to the power input side IN, the oscillator circuit OSC has a constant frequency signal due to the time constant of the capacitor C 3 and the resistors R 3 and R 4 . TR 1 ) triggers the base, and accordingly, the emitter-collector of transistor TR 1 is turned on, so that power supply B + emits light-emitting diodes LED 1 and LED 2 grounded by resistor R 14 . In addition, the phototransistor TR, which receives such a light beam, is turned on and is connected to the ground through a grounded resistor R 6 to prevent the charge of the capacitor C 5 of the operational amplifier OP 1 OP 1 . There is no signal at the comparison input terminal and therefore no signal at the output of the OP amp (OP 1 ).

이와같은 상태는 주로 접근금지구역 예를들어 출입문의 일측에는 발광다이오드(LED1,LED2)를 설치하고 이와 대칭되게 타측에는 수광소자인 포토트랜지스터(TR)를 설치하는 경우 외부침입자가 (적외선은 보이지 않으므로) 상기한 적외선을 차단하고 통과하는 경우, 즉, 물체가 광선을 막는 경우 지금까지 도통상태에 있던 포토트랜지스터(TR)가 ON에서 OFF가 되므로 순간적으로 콘덴서(C5)를 통해 OP암프(OP1)의 비교입력단자에서 전원이 가해지므로 OP암프(OP1)의 출력측에는 증폭된 신호가 발생되어 콘덴서(C6)를 통해 다시 OP암프(OP1)의 비교입력단자에 인가되며, 그 신호는 멀티바이브레이터지연회로(MV)에 인가됨으로서 출력측에는 저항(R11)과 콘덴서(C10)의 시정수에 따른 신호가 트랜지스터(TR2)의 베이스를 트리거하게되어 전원 B+과 콜렉터 사이에 연결된 릴레이(RY)를 여자하게 되는 것이다.This state is mainly forbidden in the case of the installation of light emitting diodes (LED 1 , LED 2 ) on one side of the door and the phototransistor (TR), which is a light receiving element on the other side symmetrically to the outside intruders (infrared rays not visible) if the block and passing through the infrared, that is, OP Amphoe object through the instantaneous capacitor (C 5), since the OFF in the phototransistor (TR) is oN, which was in a conductive state when stopping the beam so far ( since power is applied to the comparison input terminal of the OP 1) is the output side, the amplified signal of the OP Amphoe (OP 1) generated and applied again to the comparison input terminal of the OP Amphoe (OP 1) via a capacitor (C 6), that Since the signal is applied to the multivibrator delay circuit (MV), the signal according to the time constant of the resistor (R 11 ) and the capacitor (C 10 ) on the output side triggers the base of the transistor (TR 2 ) so that between the power supply B + and the collector It will excite relay (RY) connected to.

또, 이때 이와같은 신호는 콘덴서(C7,C8)를 충전시키게 되므로 출력신호가 끓어지더라도 콘덴서(C7,C8)에 충전되었던 전하가 방전하는 동안 계속해서 트랜지스터(TR2)를 도통시켜 오동작을 방지하며, 따라서 도시하지 않은 릴레이(RY)의 접점에 연결되는 경보기 또는 경보등을 점등시켜 경보를 발하여 침입자가 출입문을 통과했음을 알려주게 되는 것이다.At this time, such a signal charges the capacitors C 7 and C 8 so that even when the output signal is boiled, the transistor TR 2 continues to conduct while the charges charged in the capacitors C 7 and C 8 are discharged. It prevents a malfunction, and thus lights an alarm or alarm light connected to a contact of a relay (RY), not shown, to alert an intruder by passing an entrance door.

도면중 다이오드(D1,D2)는 일방향성이기 때문에 전류 신호의 역류를 방지하기 위한 것이며, 또 휘드백회로를 구성하고 있는 콘덴서(C9)와 저항(R8)은 연산증폭회로인 OP암프(OP1)의 증폭을 높여주는 역할을 한다.Since diodes D 1 and D 2 are unidirectional in the figure, they are intended to prevent reverse flow of the current signal, and capacitor C 9 and resistor R 8 constituting the feedback circuit are OP amplification circuits. It increases the amplification of the amp (OP 1 ).

따라서 본 고안에서 발광다이오드(LED1,LED2)와 수광소자인 포토트랜지스터(TR)를 한조로 하여 출입문이나 예상되는 접근 통로의 양측에 각기 설치되는 경우 경보스위치장치로서의 역할을 다할수 있는 실용적인 고안인 것이다.Therefore, in the present invention, when the light emitting diodes (LED 1 , LED 2 ) and phototransistor (TR), which are light-receiving elements, are installed on both sides of the door or the expected access passage, the practical design can fulfill the role as an alarm switch device. It is

또 본 고안에서 발광다이오드와 수광소자인 포토트랜지스터는 아주 작은 것이므로 출입문이나 접근로에 외부사람이 보이지 않게 매설시켜 설치할 수 있으며, 또 이와같은 발광다이오드와 포토트랜지스터는 수개로 각기 높이를 달리하여 설치함으로서 침입자의 크고 작음에 관계 없이 포착하여 경보할 수 있어서 확실하게 경보를 할 수 있다.In addition, the light emitting diodes and phototransistors, which are light-receiving elements in the present invention, are very small, so that they can be installed invisible to an outside door or access path, and such light emitting diodes and phototransistors may be installed in different heights. Regardless of the intruder's size, it can be caught and alarmed, so that the alarm can be reliably alerted.
