본 고안은 키폰전화기의 콜미터링 주파수제어에 관한 것으로, 특히 키폰전화기의 요금 정산기능을 수행하는 콜미터링 주파수(12/16㎑)변화에 따라 콜미터링 주파수를 제어하도록 하는 키폰전화기의 콜미터링 주파수검출회로에 관한 것이다.The present invention relates to the call metering frequency control of a key phone, particularly, the call metering frequency detection of a key phone to control the call metering frequency according to the change of the call metering frequency (12/16 ㎑) which performs the charge settlement function of the key phone. It is about a circuit.

일반적으로 콜미터(call meter)란 가입자의 통화횟수의 계수 또는 어떤 장치의 사용횟수를 계수하기 위해 쓰이는 장치로 콜미터링 주파수를 이용하여 통화요금산정기능 수행한다.In general, a call meter is a device used to count the number of calls of a subscriber or the number of times a device is used to perform a call charge calculation function using a call metering frequency.

이와 같은 통화요금산정기능에 수행에 이용되는 콜미터링 주파수는 12㎑ 또는 16㎑로 되어 있어 각 나라마다 12㎑나 16㎑인 콜미터링주파수를 사용하여 요금산정을 하고 있다.The call metering frequency used to perform the call rate calculation function is 12 kHz or 16 kHz, and the call metering frequency of 12 kHz or 16 kHz is calculated for each country.

따라서 종래의 커폰전화기는 콜미터링 주파수(12/16㎑)마다 별도의 장치를 이용하여 요금산정기능을 수행하였다.Therefore, the conventional phone phone performed the charge calculation function by using a separate device for each call metering frequency (12/16 kHz).

그러나 이와 같은 종래 키폰전화기는 콜미터링 주파수(12/16㎑)마다 별도의 장치를 이용하여 요금산정기능을 수행하므로 인해 각 주파수에 대한 호환성을 없고 관리성 문제점이 있었다.However, such a conventional phone phone has a charge calculation function by using a separate device for each call metering frequency (12/16 인해), and thus there is no compatibility for each frequency and there is a problem in manageability.

따라서 본 고안의 목적은 키폰전화기의 요금정산기능을 수행하는 콜미터링 주파수(12/16㎑)변화에 따라 자동으로 콜미터링 주파수를 제어하도록 하는 키폰전화기의 콜미터링 주파수검출회로를 제공함에 있다.Accordingly, an object of the present invention is to provide a call metering frequency detection circuit of a key phone for automatically controlling the call metering frequency according to the change of the call metering frequency (12/16 kHz) which performs the charge settlement function of the key phone.

And attenuating circuit 6 for attenuating the amplitude of various signals flowing into the tip and ring terminal Tin.

이와 같이 구성한 본 고안의 동작 및 효과를 상세히 설명하면, 먼저 콜미터링주파수를 12㎑를 사용하는 지역에서 팁 및 링단자(Tip)(Ring)로 12㎑의 콜미터링 주파수가 유입되어 트랜스(T1)의 1차측 권선에 인가됨과 아울러 외부로부터 하이제어신호(cs)가 저항(R9)을 통해 트랜지스터(TR1)의 베이스에 인가되면 상기 트랜스(T1)의 베이스 및 인버터(G)를 통해 위상반전되어 트랜지스터(TR2)의 베이스에 인가되면 상기 트랜스(T1)의 1차측권선에 인가된 12㎑의 콜미터링 주파수는 2차측권선으로 유기되어 저항(R1)(R2)에 의해 분압된 후 제1신호검출부(1)내의 콘덴서(C2)를 통해 제1톤 디코더(1Q)의 입력단자(IN1)에 인가됨과 아울러 제2신호 검출부(2)내의 콘덴서(C3)를 통해 제2톤디코더(2a)의 입력단자(IN2)에 인가된다.Referring to the operation and effects of the present invention configured in this way in detail, first the call metering frequency of 12 로 is introduced into the tip and ring terminal (Ring) in the region using the call metering frequency of 12 트랜스 trans (T1) When the high control signal cs is applied from the outside to the base of the transistor TR1 through the resistor R9, the phase is reversed through the base of the transformer T1 and the inverter G. When applied to the base of TR2, a 12 kHz call metering frequency applied to the primary winding of the transformer T1 is induced by the secondary winding and divided by the resistors R1 and R2, and then the first signal detection unit 1) is applied to the input terminal IN1 of the first tone decoder 1Q through the condenser C2 in the input signal and the input terminal of the second tone decoder 2a through the condenser C3 in the second signal detector 2. Is applied to (IN2).

한편, 상기 주파수 제어부(5)내의 트랜지스터(TR1) 및 릴레이(RL1)는 외부로 부터 입력전 하이제어신호(CS)에 의해 턴-온되고 트랜스(TR2)는 인버터(G)를 통해 위상반전된 로우신호에 의해 턴-오프된다.Meanwhile, the transistor TR1 and the relay RL1 in the frequency controller 5 are turned on by the high control signal CS before input from the outside and the transformer TR2 is phase-inverted through the inverter G. It is turned off by the low signal.

상기 트랜지스터(TR1) 및 릴레이(RL1)가 턴-온됨에 따라 가변저항(VR2) 및 콘덴서(C9)에 의해 세팅된 16㎑ 주파수(1/VR2*C9)는 릴레이(RL1), 트랜지스터(TR1)를 순차통해 접지되어 제1신호검출부(2) 내의 제2 톤디코더(2a)는 디스에이블된다.As the transistor TR1 and the relay RL1 are turned on, the 16 kHz frequency (1 / VR2 * C9) set by the variable resistor VR2 and the capacitor C9 becomes the relay RL1 and the transistor TR1. Are sequentially grounded so that the second tone decoder 2a in the first signal detection unit 2 is disabled.

한편, 상기 트랜지스터(TR2)가 턴-오프함에 따라 제1신호검출부(1) 내의 제1톤더코더(1a)는 기설정된 가변저항(VR1) 및 콘덴서(C6)에 의해 상기 단자(IN1)로 입력된 12㎑콜미터링주파수를 디코딩하여 출력단자(out)를 통해 로우신호를 출력한다.Meanwhile, as the transistor TR2 is turned off, the first tone coder 1a in the first signal detection unit 1 is input to the terminal IN1 by a predetermined variable resistor VR1 and a capacitor C6. A low signal is output through the output terminal (out) by decoding the 12 kHz call metering frequency.

상기 출력된 로우신호는 제1버퍼(3)를 통해 버퍼링된 후 저항(R4)를 통해 CPU로 출력된다.The output low signal is buffered through the first buffer 3 and then output to the CPU through the resistor R4.

한편 콜미터링주파수를 16㎑를 사용하는 지역에서 팁 및 링단자(Tp)(Rng)로 16㎑의 콜미터링주파수가 유입되어 트랜스(TR1)의 1차측권선에 인가됨과 아울러 로우신호인 외부제어신호(CS)가 저항(R9)을 통해 트랜지스터(TR1)의 베이스 및 인버터(G)를 통해 위상반전되어 트랜지스터(TR2)의 베이스에 인가되면 상기 트랜스(T1)의 1차측권선에 인가된 16㎑의 콜미터링주파수는 2차측권선으로 유기되어 저항(R1)(R2)에 의해 분압된 후 제1신호검출부(1)내의 콘덴서(C3)를 통해 제1톤 디코더(1Q)의 입력단자(in2)에 인가됨과 아울러 제2신호검출부(2)내의 콘데서(C3)를 통해 제1톤 디코더(1a)의 입력단자(IN2)에 인가된다.On the other hand, in the region using 16 kHz call metering frequency, 16 kHz call metering frequency flows into the tip and ring terminal (Tp) (Rng) and is applied to the primary winding of transformer (TR1). When CS is phase-inverted through the base of transistor TR1 and inverter G through resistor R9 and is applied to the base of transistor TR2, the 16 kHz applied to the primary winding of transformer T1 is applied. The call metering frequency is induced by the secondary winding and divided by the resistors R1 and R2, and then is fed to the input terminal in2 of the first tone decoder 1Q through the condenser C3 in the first signal detection unit 1. In addition, it is applied to the input terminal IN2 of the first tone decoder 1a through the capacitor C3 in the second signal detection unit 2.

한편, 상기 주파수제어부(5)내의 트랜지스터(TR1) 및 릴레이(RL1)는 로우신호인 외부제어신호(CS)에 의해 턴-오프되고 트랜지스터(TR2)는 인버터(G)를 통해 위상반전된 하이신호에 의해 턴-온된다.On the other hand, the transistor TR1 and the relay RL1 in the frequency controller 5 are turned off by the external control signal CS, which is a low signal, and the transistor TR2 is a high signal whose phase is inverted through the inverter G. Is turned on.

상기 트랜지스터(TR2)가 턴-온됨에 따라 가변저항(VR1) 및 콘덴서(C6)에 의해 세팅된 12㎑ 주파수(1/(VR1*C6)는 트랜지스터(TR2)를 순차통에 접지되어 제1신호검출부(2) 내의 제1 톤디코더(1a)는 디스에이블된다.As the transistor TR2 is turned on, the 12 kHz frequency 1 / (VR1 * C6) set by the variable resistor VR1 and the capacitor C6 is grounded to the transistor TR2 in sequence so that the first signal is turned on. The first tone decoder 1a in the detector 2 is disabled.

상기 트랜지스터(TR1)가 턴-오프됨에 따라 제2신호검출부(2)내의 제2톤디코더(2a)는 기설정된 가변저항(VR2) 및 콘덴서(C9)에 의해 상기 입력단자(IN2)로 입력된 16㎑콜미터링 주파수를 디코딩하여 단자(out)를 통해 로우신호를 출력된다.As the transistor TR1 is turned off, the second tone decoder 2a in the second signal detector 2 is input to the input terminal IN2 by a predetermined variable resistor VR2 and a capacitor C9. The low signal is outputted through the terminal (out) by decoding the 16kHz call metering frequency.

상기 출력된 로우신호는 제2 버처(4)를 통해 버퍼링 된 후 저항(R5)을 통해 CPU로 출력되게 되는 것이다.The output low signal is buffered through the second greener 4 and then output to the CPU through the resistor R5.

이상에서 상세히 설명한 바와 같이 본 고안은 요금정산기능을 수행하는 콜미터링주파수의 변화에 따라 자동으로 제어함으로써 각각 다른 콜미터링주파수를 사용하고 있는 국가에 관계없이 어느 국가에서나 편리하게 사용 할 수 있는 효과 있다.As described in detail above, the present invention has an effect that can be conveniently used in any country regardless of the country using different call metering frequencies by automatically controlling the change of the call metering frequency performing the charge settlement function. .
