본 고안은 송화여부를 감지하여 초기상태로 환원시링 수 있는 앤서링폰의 송화감지회로에 관한 것이다.The present invention relates to a call detection circuit of an answering phone that can detect whether or not to send the call back to the initial state.
앤서링폰은 부재중에 녹음된 내용을 공화자에게 알리며 공화자의 공화 내용을 녹음할 수 있게한 전화기로서 실생활에 사용하기 편리한 이점이었다.The answering phone is a convenient phone to use in real life as a telephone that informs the republican of the recorded contents while away from the party.
그러나 앤서링폰(Answering Phone)에 있어서 외부의 전화 내용을 녹음하다가 송화가 끝났을 때에 이를 감지하여 초기상태를 환원시키지 못하면 다음 전화를 수신할 수 없을 뿐만아니라 테이프에 계속적으로 선로의 비트잡음만 녹음되므로 송화 감지회로(Colling Party Control)가 필요하게 되는 것이었다.However, in the Answering Phone, if you record the contents of an external phone and detect it when the call is over and fail to restore the initial state, you will not be able to receive the next call and only the bit noise of the track will be continuously recorded on the tape. There was a need for a calling party control.
본 고안의 목적은 전화선로에서 인가되는 펄스 잡음에 따라서 송화 여부를 감지하여 마이크로 프로세서에 인가시켜 줄 수 있는 앤서링폰의 송와 감지회로를 제공하고자 하는 것으로 전화선에서 유기되는 전압을 미분시켜 트랜지스터에 인가되도록 구성하며 마이크로 프로세서의 콘트롤 출력에 의하여 트랜지스터가 제어되도록 구성시켜 콘덴서에 충전되는 유기전압을 마이크로 프로세서에서 감지하도록 구성시켜 된 것이다.An object of the present invention is to provide a song and a detection circuit of an ansaging phone that can detect a call or not and apply it to a microprocessor according to the pulse noise applied from a telephone line. The transistor is controlled by the control output of the microprocessor so that the microprocessor senses the induced voltage charged in the capacitor.
이를 제1도에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to FIG. 1 as follows.
전화선로와 트랜스(T)를 통하여 매칭되게 하여 저주파패스용 콘덴서(C1) 및 임피던스 매칭용 저항(R1)에 인가된 상태 신호가 저항(R2), 콘덴서(C2)로 구성된 미분회로(10)에서 미분된 후 다이오드(D1)와 저항(R3)(R4)을 통하여 트랜지스터(Q1)를 구동시키도록 구성하고 통화 중에 출력되는 마이크로 프로세서의 콘트롤 출력이 트랜지스터(Q3)를 통하여 트랜지스터(Q2)의 에미터측에 인가되게 구성시켜 송화 후 전화기를 내려 놓을(Hang-up) 때 트랜지스터(Q2)가 구동하여 저항(R7)(R8)으로 분배된 전압을 콘덴서(C3)에 충전시킨 후 다이오드(D2)를 통하여 트랜지스터(Q1)가 계속적인 도통상태가 유지되도록 구성한 것이다.Differential circuit composed of resistor R 2 and capacitor C 2 so that the state signal applied to low frequency pass capacitor C 1 and impedance matching resistor R 1 by matching with telephone line and transformer T is matched. After differentiating at (10), it is configured to drive transistor Q 1 through diode D 1 and resistor R 3 (R 4 ) and the control output of the microprocessor output during the call is transistor Q 3 . Is configured to be applied to the emitter side of the transistor (Q 2 ) through the transistor when the phone is put down (Hang-up), the transistor (Q 2 ) is driven to divide the voltage distributed to the resistor (R 7 ) (R 8 ) After charging to C 3 , the transistor Q 1 is configured to maintain a continuous conduction state through the diode D 2 .
이와 같이 구성된 본 고안을 제2도의 각부 파형도에 의하여 설명하면, 송화자가 앤서링폰과 통화 완료 후 전화기를 내려 놓을 때(Hang-up) 제2도의 (a)도와 같은 검지펄스(ㄱ)가 연속되게 전화선을 통하여 인각하게 된다.When the present invention configured as described above is explained by the waveform diagram of each part of FIG. 2, when the talker puts down the phone after completing the call with the answering phone (Hang-up), the detection pulse (a) as shown in FIG. It is usually saved through the telephone line.
그리고 이 검지펄스는 트랜스(T)의 2차측을 통하여 (b)도와 커플링된 전압이 발생되고 콘덴서(C2)와 저항(R2)으로 구성된 미분회로(10)에서 미분된 파형이 나타나게 되므로 저항(R2)치에 의하여 발생된 펄스중에 높은 레벨의 펄스만 출력되게 된다(c도).The detection pulse generates a voltage coupled with the diagram (b) through the secondary side of the transformer (T), and a differential waveform appears in the differential circuit (10) composed of the capacitor (C 2 ) and the resistor (R 2 ). Only pulses of a high level are outputted among the pulses generated by the resistance R 2 (c degree).
그리고 이 펄스는 다이오드(D1)를 통하여 양(+)부분의 미분파형(d도)이 저항(R3)(R4)으로 바이어스 분배되어 트랜지스터(Q1)의 베이스측에 인가되어서 (e도) 트랜지스터(Q1)를 구동시키게 된다.The pulse is biased by a positive portion (d degrees) of the positive portion through the diode D 1 and distributed to the resistor R 3 (R 4 ) and applied to the base side of the transistor Q 1 (e). The transistor Q 1 is driven.
트랜지스터(Q1)가 도통되면 콜렉터측이 저전위 상태가 되어 (f도)와 같은 파형이 출력되고 이때 트랜지스터(Q2)의 베이스측은 에미터측 보다 저전위가 되어 트랜지스터(Q2)도 도통하게 되므로 트랜지스터(Q3)를 도통시키는 마이크로 프로세서의 콘트롤 출력은 트랜지스터(Q2)를 통하여 상태신호의 출력신호가 저항(R7)(R8)으로 분배되어 콘덴서 (C3)에 충전하게 된다.When transistor Q 1 is turned on, the collector side is in a low potential state to output a waveform such as (f degrees), and at this time, the base side of transistor Q 2 is lower than the emitter side so that transistor Q 2 is also conductive. Therefore, the control output of the microprocessor conducting the transistor Q 3 conducts the output signal of the state signal through the transistor Q 2 to the resistor R 7 and R 8 to charge the capacitor C 3 .
즉 마이크로 프로세서로 입력되는 펄스는 순간적으로 콘덴서(C3)에 충전(g도)되는 것으로 이 충전전압이 다이오드(D2)의 도통 전압보다 높게되면 다이오드(D2)가 도통되어 트랜지스터(Q1)를 계속 도통상태로 유지할 수 있게 되어 노우드(H)점에 고전위 상태신호가 인가(h도)되므로 마이크로 프로세서의 입력측에 하이레벨 신호가 인가되어 마이크로 프로세서에서 통화가 끝난 시점을 감지할 수가 있게 된다. 이와같이 마이크로 프로세서에서 통화가 끝난 시점을 감지하면 프로그램된 순서대로 각 제어부를 제어하여 전화를 끊으며, 마이크로 프로세서의 콘트롤 출력도 차단시키므로 마이크로 프로세서의 입력측도 초기상태인 저전위 상태로 환원되어 재통화를 할 수 있는 상태가 되는 것이다.I.e. the pulse that is input to the microprocessor momentarily capacitor (C 3) to the charge (g degrees) when as the charge voltage is higher than the conduction voltage of the diode (D 2) is a diode (D 2) is conducting a transistor (Q 1 ), The high potential signal is applied to the input of the microprocessor so that the microprocessor can detect when the call is over. Will be. In this way, when the microprocessor detects the end of the call, the control unit terminates the call by controlling each control unit in the programmed order. Since the control output of the microprocessor is also cut off, the input side of the microprocessor is also returned to the low-potential state, which is the initial state, to resume the call. You can do it.
이상에서와 같이 본 고안은 매칭된 트랜스(T)를 통하여 인가되는 선로전압을 감지하여 송화 후 인가되는 펄스전압을 미분하여 이 전압이 트랜지스터(Q1)를 구동하도록 하고, 마이크로 프로세서의 콘트롤 출력으로 트랜지스터(Q2)가 제어되어 콘덴서(C3)에 충전되는 충전전압에 따라 송화 여부를 마이크로 프로세서가 감지할 수 있도록 함으로써 부재중에 완벽한 동작을 수행할 수 있는 앤서링폰의 송화 감지회로를 제공할 수가 있는 것이다.As described above, the present invention senses the line voltage applied through the matched transformer T and differentiates the applied pulse voltage after the transmission to drive the transistor Q 1 and to the control output of the microprocessor. The transistor Q 2 is controlled so that the microprocessor can detect whether or not a call is made in accordance with the charging voltage charged in the capacitor C 3 , thereby providing a call detection circuit of an angering phone capable of performing a perfect operation in the absence. It is.
