본 고안은 밧데리 기준 전압과 비교하여 밧데리의 교체시기가 되면 경고음을 울린 후 세트의 동작을 정지시키도록 하여 밧데리의 소모를 줄일 수 있는 밧데리 전압 제어 회로에 관한 것이다.The present invention relates to a battery voltage control circuit that can reduce the consumption of the battery by stopping the operation of the set after the alarm sound when the battery replacement time compared to the battery reference voltage.

종래에는 밧데리를 사용할 때 밧데리의 교체 시기를 사용자가 알 수 있도록 해주는 경보 표시 장치가 분명치 않았기 때문에 밧데리의 교체 시기가 되기전에 교체 하거나 또는 교체 시기를 넘김으로 해서 재사용을 할 수 없을 정도로 방전이 되어 경제적인 손실을 초래 하였다.In the past, when the battery was used, the alarm display device to allow the user to know when to replace the battery was not clear. It caused a loss of phosphorus.

본 고안은 이와 같은 점을 감안하여 밧데리의 교체 시기를 분명히 알 수 있도록 경보음을 발생해 준 후 세트를 동작 시키지 못하도록 하여 밧데리의 손실을 막아주는 밧데리 전압 제어 회로로써 밧데리의 전압과 기준 전압을 비교기에서 비교하여 다이오드를 통한 후 전압 분배부의 전압과 앤드게이트에 인가시킴으로써 앤드게이트의 출력으로 경고 표시부와 정지 제어부를 제어하도록 한 것이다.In consideration of this, the present invention is a battery voltage control circuit that prevents the battery from being lost by generating an alarm sound to clearly know when to replace the battery and preventing the battery from being operated. In comparison with, the warning display unit and the stop controller are controlled by the output of the AND gate by applying the voltage through the diode and the AND gate to the AND gate.

이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

입력단자(1)에 밧데리 전압을 입력시켜 저항(R1)(R3)과 가변저항(VR) 및 콘덴서(C1)를 거쳐 비교기(OP)의 타측단자(-)에 인가시키고 일측단자(+)에는 입력단자(2)로 기준 전압을 입력시켜 콘덴서(C2)를 통한 후 인가되도록 비교부(5)를 구성한다.The battery voltage is input to the input terminal (1) and applied to the other terminal (-) of the comparator (OP) through the resistor (R 1 ) (R 3 ), the variable resistor (VR) and the capacitor (C 1 ), and the one terminal ( The comparator 5 is configured to apply a reference voltage to the input terminal 2 through +) and then apply the same through the capacitor C 2 .

그리고 비교기(OP)의 출력이 저항(R4)(R5)와 다이오드(D1)를 거쳐 콘덴서(C3)와 저항(R7)을 통하여 앤드게이트(AN1)의 일측단자에 인가시킴과 동시에 다이오드(D2)와 저항(Rc)(R8) 및 콘덴서(C4)를 통하여 앤드게이트(AN2)의 타측단자에 인가되게 구성하고 전원(Vcc)이 다이오드(D3∼D5)와 콘덴서(C5)(C6) 및 저항(R9)(R10)으로 구성된 전압 분배부(10)를 통하여 앤드게이트(AN1)의 타측단자 및 앤드게이트(AN2)의 일측단자에 인가되게 구성한 후 앤드게이트(AN1)의 출력은 경고표시부(15)에는 앤드게이트(AN2)의 출력은 인가시키며 다이오드(DG)를 통하여 앤드게이트(A2)의 타측단자에 궤환되게 인가시킴과 동시에 정지제어부(20)에 인가시켜 구성한다.And the output of the comparator (OP) resistance (R 4) (R 5) and Sikkim applied to one terminal of the diode capacitor (C 3) and a resistor (R 7) the AND gate (AN 1) through a through a (D 1) At the same time, it is configured to be applied to the other terminal of the AND gate (AN 2 ) through the diode (D 2 ), the resistor (R c ) (R 8 ) and the capacitor (C 4 ) and the power supply (Vcc) is the diode (D 3 ~ D 5) and a capacitor (C 5) (C 6) and a resistor (R 9) (R 10) to the configured voltage distributor (10) through aND gates (one side of the other terminal and the aND gate (aN 2) of the aN 1) After being configured to be applied to the terminal, the output of the AND gate (AN 1 ) is applied to the warning display unit 15 and the output of the AND gate (AN 2 ) and fed back to the other terminal of the AND gate (A 2 ) through the diode (D G ). It is configured to apply to the stop control unit 20 at the same time to apply.

이와같이 구성된 본 고안은 입력단자(1)로 입력되는 밧데리 전압은 저항(R1)(R3)과 비교기(OP)의 타측단자(-)에 일정전압 이상의 전압이 걸리도록 하는 가변저항(VR) 및 교류 성분 차단용 콘덴서(C1)를 통하여 비교기(OP)의 타측단자(-)에 인가시키고 일측단자(+)에는 입력단자(2)로 입력되는 기준 전압을 저항(R2)과 콘덴서(C2)를 거쳐 인가되도록 비교부(5)를 구성하여 비교기(OP)에서 밧데리 전압과 기준 전압을 비교하도록 한다.According to the present invention configured as described above, the battery voltage input to the input terminal 1 is a variable resistor VR such that a voltage of a predetermined voltage or more is applied to the resistors R 1 and R 3 and the other terminal of the comparator OP. And a reference voltage input to the other terminal (-) of the comparator OP through the AC component blocking capacitor C 1 and the one terminal (+) to the resistor R 2 and the capacitor ( The comparator 5 is configured to be applied via C 2 ) to compare the battery voltage with the reference voltage in the comparator OP.

이때 밧데리 전압리 기준 전압보다 클 경우는 비교기(OP)의 출력은 로우 전압이 출력되므로 다이오드(D1)는 개방된 상태가 되어 저항(R4)(R5)(R7)과 콘덴서(C3)를 통하여 앤드게이트(AN1)의 일측 단자에 로우 전압이 인가되도록 하고 또한 다이오드(D2)를 거친 로우 전압은 저항(Rc)(Rs)과 콘덴서(C4)를 통하여 앤드게이트(AN2)의 타측단자에 로우 전압이 걸리게 된다.At this time, if the battery voltage is higher than the reference voltage, the output of the comparator OP outputs a low voltage, so that the diode D 1 is open and the resistors R 4 , R 5 , R 7 and the capacitor C are A low voltage is applied to one terminal of the AND gate AN 1 through 3 ), and the low voltage through the diode D 2 is applied to the AND gate through the resistor R c (R s ) and the capacitor C 4 . A low voltage is applied to the other terminal of (AN 2 ).

그리고 전원(Vcc)이 보호용 다이오드(D3∼D5)와 교류 차단용 콘덴서(C5)(C6) 및 저항(R9)(R10)을 통하여 앤드게이트(AN1)(AN2)의 타측단자 및 일측단자에 하이 전압을 인가시키므로 앤드게이트(AN1)(AN2)의 출력은 로우 전압이 나타나게 되어 경고 표시부(15)와 정지제어부(20)는 동작하지 않게되므로 사용자는 밧데리를 안심하고 계속 사용할 수 있는 것이다.And the power supply (Vcc) through the protective diode (D 3 ~ D 5 ), the AC blocking capacitor (C 5 ) (C 6 ) and the resistor (R 9 ) (R 10 ) and the gate (AN 1 ) (AN 2 ) Since high voltage is applied to the other terminal and one terminal of the output of the AND gate (AN 1 ) (AN 2 ), the low voltage appears, and the warning display unit 15 and the stop control unit 20 do not operate. You can continue using it with confidence.

그러나 밧데리 전압이 기준 전압보다 낮아지게 되면 비교기(OP)의 출력은 하이 전압이 출력되어 다이오드(D1)와 저항(R4)(R5)(R7) 및 콘덴서(C3)를 통하여 앤드게이트(AN1)의 일측 단자에 하이 전압을 인가시키게 되고 타측단자에는 전압 분배부(10)에서 하이 전압이 인가되므로 앤드게이트(AN1)의 출력은 하이전압이 되어 경고 표시부(15)를 동작시켜 경고음을 발생시키므로 사용자는 밧데리가 교체 시기가 되었음을 알게 된다.However, when the battery voltage becomes lower than the reference voltage, the output of the comparator OP is outputted with a high voltage so that the AND through the diode D 1 , the resistors R 4 , R 5 , R 7 , and the capacitor C 3 Since a high voltage is applied to one terminal of the gate AN 1 and a high voltage is applied from the voltage divider 10 to the other terminal, the output of the AND gate AN 1 becomes a high voltage to operate the warning display unit 15. The user will know that the battery is about to be replaced.

그리고 저항(R4)과 콘덴서(C3)의 시정수에 의한 시간만큼 경고표시부(15)가 동작한 후에는 비교기(OP)의 출력이 다이오드(D2)를 통하여 저항(R6)과 콘덴서(C4)에 의한 시정수에 의하여 앤드게이트(AN2)의 타측단자에도 하이 전압이 인가되고 일측단자에는 전압 분배부(10)에서의 하이 전압이 인가되어 앤드게이트(AN2)의 출력은 하이 전압이 정지 제어부(20)를 동작 시킴으로써 세트는 동작을 중지하게 된다.After the warning display unit 15 is operated for a time according to the time constant of the resistor R 4 and the capacitor C 3 , the output of the comparator OP is connected to the resistor R 6 and the capacitor through the diode D 2 . The high voltage is applied to the other terminal of the AND gate AN 2 by the time constant by (C 4 ), and the high voltage of the voltage divider 10 is applied to one terminal of the AND gate (AN 2 ). The high voltage causes the stop control unit 20 to operate so that the set stops operating.

이때 앤드게이트(AN2)의 출력을 다이오드(D6)로써 타측단자에 궤한 시킴으로써 앤드게이트(AN2)에서 한번 하이 전압이 출력되면 계속 하이 전압이 출력되므로 세트는 계속 동작을 멈춘 상태가 된다.At this time, the AND gate by gwehan the output of the (AN 2) diode to the other terminal by (D 6) Once the high voltage is output from the AND gate (AN 2), so still a high voltage, the output set is the state continues to stop operation.

이상에서와 같이 본 고안은 밧데리 전압과 기준 전압을 비교구(5)에서 비교 시킨 출력으로써 전압 분배부(10)의 출력과 함께 앤드게이트(AN1)(AN2)의 출력을 제어하여 경고 표시부(15)와 정지 제어부(20)의 동작을 제어 시킴으로써 밧데리의 교체 시기가 되기 전에는 아무런 표시를 하지 않아 사용자가 안심하고 사용할 수 있으며 밧데리의 교체 시기가 되면 경고 표시부(15)를 동작시켜 경고음을 발생시키므로 밧데리의 교체 시기가 되었음을 알려줌과 동시에 셋트의 동작을 정지 시킴으로써 밧데리의 소비를 막아주고 교체 시기를 정확히 알려주므로써 사용자가 일일이 신경을 쓰게 되는 불편함을 없애주는 것이다.As described above, the present invention compares the battery voltage and the reference voltage in the comparison port 5, and controls the output of the AND gate AN 1 (AN 2 ) together with the output of the voltage divider 10 to display a warning. By controlling the operation of the stop control unit 20 and the stopper 20, no indication is made before the battery replacement time is reached, and the user can use it with confidence. When the battery replacement time comes, the warning display unit 15 operates to generate a warning sound. Therefore, it informs that it is time to replace the battery and at the same time stops the operation of the set to prevent the consumption of the battery and accurately informs the replacement time to eliminate the inconvenience that the user cares about.
