본 고안은 전압을 검출하여 미세하게 조정 및 검사하는데 있어서, 검출된 전압을 세분하여 이를 발광다이오드의 점등 및 디지털 숫자로 표시해 주어 쉽게 전압을 조정 및 검사할 수 있도록 한 전압 조정 레벨 표시 회로에 관한 것이다.The present invention relates to a voltage adjustment level display circuit for subdividing a detected voltage into minutely detected and finely regulated and inspected voltages and displaying them by lighting and digital numbers of the light emitting diodes to easily adjust and inspect the voltages. .

SECAM 방식 TV에서 칼라 신호가 최대한 잘 나오도록 하는 IDENT 조정시 종래에는 IDENT 조정을 위하여 아날로그 방식의 전압 레벨 표시기 및 디지털 방식의 전압레벨 표시기를 사용하였다.In the case of IDENT adjustment for the best color signal output from SECAM type TV, an analog voltage level indicator and a digital voltage level indicator are used for IDENT adjustment.

그러나 아날로그 방식인 검출 전압에 대한 응답 속도가 느리고 디지털 방식은 응답 속도가 너무 빨라 작업자가 IDENT 조정시 상당한 불편을 느끼는 것이었다.However, the response speed of the analog detection voltage was slow and the digital response was too fast, which made the operator feel uncomfortable when adjusting the IDENT.

즉 아날로그 방식의 전압레벨 표시기로 IDENT를 조정하게 되면 응답 속도의 저하로 빠른 시간내에 많은 량의 작업을 수행할 수 없어 작업 속도가 느리게 되고 또한 디지털 방식의 전압 레벨 표시기는 너무 빠른 응답속도로 표시되므로 정확한 레벨의 전압을 조정하기가 곤란한 점이 있는 것이었다.In other words, if IDENT is adjusted with the analog voltage level indicator, the response speed decreases, so a large amount of work cannot be performed within a short time. Therefore, the operation speed becomes slow and the digital voltage level indicator displays too fast response speed. It was difficult to adjust the voltage at the correct level.

본 고안은 이와 같은 점을 감안하여 SECAM 방식의 TV에서 IDENT 조정시 전압을 세분하여 다수개로 구성된 발광다이오드 레벨을 점등시킴과 동시에 이를 디지털 숫자로 표시해 주어 작업자는 일차로 점등된 발광다이오드의 레벨을 보고 전압 조정을 한후 이차로 디지털 표시된 전압으로 확인할 수 있어 보다 정확하고 빠르게 IDENT 전압 조정을 할 수 있도록 한 것이다.In view of the above, the present invention breaks down the voltage during IDENT adjustment in SECAM type TV, turns on the light emitting diode level consisting of a number, and displays it as a digital number. After the voltage adjustment, the digitally displayed voltage can be checked secondly, allowing more accurate and faster IDENT voltage adjustment.

즉 본 고안에 입력 전압이 인가되면 이를 미리 셋팅시킨 레벨 만큼의 발광다이오드를 '온'시켜 표시해 줌과 동시에 디지털 숫자로 표시해 주도록 한 것으로써 발광다이오드 숫자를 많이 할수록 측정된 전압 레벨을 좀더 세분하여 표시해 줄 수 있는 것이다.In other words, when the input voltage is applied to the present invention, the light-emitting diode of the preset level is turned on and displayed, and the digital number is displayed. As the number of light-emitting diodes increases, the measured voltage level is further divided and displayed. I can give it.

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

SECAM 방식 TV의 IDENT 전압(J1), (J2)에 인가되어 다수개의 연산증폭기(OP1-OPn)의 비반전단자(+)에 인가됨과 동시에 숫자표시부(5)에서 디지털 숫자로 전압의 량이 디스플레이 되게 구성한다.It is applied to IDENT voltage (J 1 ), (J 2 ) of SECAM type TV, and is applied to non-inverting terminal (+) of a plurality of operational amplifiers (OP1-OPn) and at the same time, the amount of voltage from digital display unit (5) to digital number Configure to be displayed.

그리고 선택스위치(SW1)로 전압 조정 레벨을 선택하여 전원(B+)이 선택 전압 조정용 가변저항(VR1-VRn)과 전압 레벨의 레벨 차이를 조정하는 다수개의 가변저항(VR5-VRn)을 통하여 연산증폭기(OP1-OPn)의 반전단자(-)에 인가되게 구성한다.Then, by selecting the voltage adjustment level with the selector switch SW 1 , the power supply B + adjusts the level difference between the selection voltage adjustment variable resistors VR 1- VRn and the voltage level (VR 5- VRn). It is configured to be applied to the inverting terminal (-) of the operational amplifier (OP 1 -OPn) through.

즉 선택스위치(SW1)와 가변저항(VR1-VR4)으로 미리 조정 전압의 선택 범위를 설정한 후 설정된 전압의 각 레벨차이를 조정하는 가변저항(VR5-VRn)을 통하여 연산증폭기(OP1-OPn)의 반전단자(-)에 기준 전압을 인가시키고 연산증폭기(OP1-OPn)의 비반전단자(+)에는 잭(J1), (J2)을 통하여 인가되는 IDENT 조정 전압이 인가되게 구성한다.That is, after setting the selection range of the adjustment voltage in advance with the selection switch SW 1 and the variable resistors VR 1- VR 4 , the operational amplifier (VR 5 -VRn) adjusts the level difference between the set voltages. inverting terminal (the OP 1 -OPn) - applying a voltage based on a) and an operational amplifier (IDENT adjusting voltage applied to the non-inverting (+) terminal of the OP -OPn 1) is via a jack (J 1), (J 2 ) It is configured to be applied.

그리고 연산증폭기(OP1-OPn)의 출력은 바이어스용 저항(R1-Rn)과 다수개의 버퍼(B1-Bn)를 통하고 전류제한용 저항(R'1-R'n)이 연결된 다수개의 발광다이오드(LED1-LEDn)에 인가되게 구성한다.The outputs of the operational amplifiers OP 1 -OPn are connected to the current limiting resistors R ' 1 -R'n through bias resistors R 1 -Rn and a plurality of buffers B 1 -Bn. It is configured to be applied to the light emitting diodes (LED 1 -LEDn).

이때 발광다이오드와 함께 연산증폭기 및 전압레벨 차이를 조정하는 가변저항을 보다 더 설치 구성함에 따라 IDENT 전압 레벨 조정을 극히 정밀하게 할 수 있는 것이다.In this case, the IDENT voltage level can be adjusted very precisely by installing and configuring the LED and the variable resistor for adjusting the difference between the operational amplifier and the voltage level.

이와 같이 구성된 본 고안의 작용효과를 살펴본다.Looking at the effect of the present invention configured as described above.

먼저 조정하고자 하는 IDENT 전압은 테스트 포인트에서 잭(J1), (J2)으로 인가시켜 주어 조정시킬 IDENT 전압이 숫자표시부(5)에서 디지털 숫자로 표시됨과 동시에 각 연산증폭기(OP1-OPn)의 비반전단자(+)에 인가되게 된다.First, the IDENT voltage to be adjusted is applied to the jack (J 1 ), (J 2 ) at the test point so that the IDENT voltage to be adjusted is displayed as digital number on the numeric display part (5) and each operational amplifier (OP 1 -OPn) Is applied to the non-inverting terminal of (+).

이때 숫자표시부(5)는 어떠한 전압이 인가되었을 때 이를 디지털 값으로 변환시킨 후 7-세그먼트 등을 구동시켜 디지털 숫자로 표시되게 하는 공지의 기술내용을 이용한다.At this time, the numeric display unit 5 uses a known technology for converting the voltage into a digital value when a certain voltage is applied and then driving the 7-segment to display the digital number.

따라서 SECAM 방식 TV의 IDENT 조정 전압은 잭(J1), (J2)에 인가되어 공지의 숫자표시부(5)에서 표시되어짐과 동시에 각 연산증폭기(OP1-OPn)의 비반전단자(+)에 인가되게 된다.Therefore, the IDENT adjustment voltage of SECAM type TV is applied to the jacks J 1 and J 2 and displayed on the well-known numeric display section 5, and at the same time, the non-inverting terminal of each operational amplifier OP 1 -OPn (+). Will be applied to.

한편 SECAM 방식 TV의 IDENT 전압은 실제 4∼6V와 9∼11V외 2가지 경우가 있게 되며 이를 본 고안의 회로를 이용하여 모두 조정하기 위해서는 조정 전압의 범위(4∼6V, 9∼11V)에 따라 선택스위치(SW1)를 절환시켜 주어야 한다.On the other hand, there are two cases of IDENT voltage of SECAM type TV except 4 ~ 6V and 9 ~ 11V, and to adjust them all using the circuit of the present invention, according to the range of adjustment voltage (4 ~ 6V, 9 ~ 11V). The selector switch (SW 1 ) must be switched.

이같이 조정 전압의 범위에 따라 선택스위치(SW1)를 절환시키게 되면 가변저항(VR1-VR4)에 의해 설정된 전압이 각 연산증폭기(OP1-OPn)의 반전단자(-)에 인가되게 되며 이때 반전단자(-)에 인가되는 전압은 가변저항(VR5-VRn)을 이용하여 각 전압 레벨 차이를 설정시킨다.When the selector switch SW 1 is switched according to the range of the adjustment voltage, the voltage set by the variable resistors VR 1- VR 4 is applied to the inverting terminals (-) of each of the operational amplifiers OP 1- OPn. At this time, the voltage applied to the inverting terminal (-) sets the difference of each voltage level by using the variable resistor (VR 5- VRn).

이때 가변저항(VR4-VRn)의 전압 레벨 차이 설정은 사용자의 외도 및 연산증폭기의 구성 숫자에 따라 0.1V 간격으로 하든가 또는 0.01V 간격으로 하는가는 구성상 자유롭게 할 수 있는 것이다.At this time, the voltage level difference setting of the variable resistor (VR 4- VRn) can be freely configured at 0.1V interval or 0.01V interval according to the configuration of the user's induction and operational amplifier.

즉 조정 전압의 레벨 설정은 가변저항(VR1-VR4)을 선택하는 선택스위치(SW1)의 선택에 의하여 4-6V 또는 9-11V가 선택되어지게 되며 이렇게 선택된 조정 전압레벨은 가변저항(VR5-VRn)에서 2레벨 차이가 다시 설정된 후 연산증폭기(OP1-OPn)의 반전단자(-)에 인가되게 된다.That is, 4-6V or 9-11V is selected by selecting the selector switch SW 1 to select the variable resistors VR 1- VR 4 . After the two-level difference is set again in VR 5 -VRn, it is applied to the inverting terminal (−) of the operational amplifiers OP 1 -OPn.

이와 같이 연산증폭기(OP1-OPn)의 반전단자(-)에는 선택스위치(SW1)로 선택한 조정 전압이 가변저항(VR5-VRn)에서 2레벨의 차이가 설정된 후 인가되게 되며 연산증폭기(OP1-OPn)의 비반전 단자(+)에는 IDENT 조정 전압 레벨이 그대로 인가되게 된다.As such, the adjustment voltage selected by the selection switch SW 1 is applied to the inverting terminal (-) of the operational amplifiers OP 1- OPn after the difference between the two levels is set in the variable resistors VR 5- VRn. The IDENT adjustment voltage level is applied to the non-inverting terminal (+) of OP 1 -OPn as it is.

따라서 연산증폭기(OP1-OPn)에서는 입력 전압을 차동 증폭하여 출력시키게 되며 이러한 차동증폭기(OP1-OPn)의 출력은 바이어스용 저항(R1-Rn)과 버퍼(B1-Bn) 및 전류제한용 저항(R'1-R'n)을 통하여 발광다이오드(LED1-LEDn)의 구동을 제어하게 된다.Therefore, in the operational amplifier OP 1 -OPn, the input voltage is differentially amplified and output. The outputs of the differential amplifiers OP 1 -OPn are bias resistors R 1 -Rn, buffers B 1 -Bn, and current. The driving of the light emitting diodes LED 1 to LED n is controlled through the limiting resistors R ' 1 to R'n.

즉 차동증폭기(OP1-OPn)의 반전단자(-)에는 선택스위치(SW1)로 선택한 조정 전압 레벨이 가변저항(VR1-VRn)에 의한 레벨 차이만큼씩의 차이를 두고 인가되게 되고 차동증폭기(OP1-OPn)의 비반전단자(+)에는 IDENT 조정 전압이 인가되게 되므로 차동증폭기(OP1-OPn)에서는 이러한 전압차에 의한 출력을 출력시키게 된다.That is, to the inverting terminal (-) of the differential amplifier OP 1 -OPn, the adjustment voltage level selected by the selection switch SW 1 is applied with the difference by the level difference by the variable resistors VR 1- VRn. since amplifier (OP 1 -OPn) a non-inverting terminal (+) is IDENT adjustment voltage to be applied, thereby the output of the output due to this voltage difference the differential amplifier (OP 1 -OPn).

따라서 차동증폭기(OP1-OPn)에서는 비반전 단자(+)전압이 높을 때만 하이레벨을 출력시키고 낮을 경우에는 로우 레벨을 출력시키게 되며 이에 따라 발광다이오드(LED1-LEDn)의 구동이 제어되게 된다.Therefore, the drive of the differential amplifier (OP 1 -OPn) the non-inverting terminal (+) when the output is low and a high level only when the high voltage, and thereby outputs a low level In the light emitting diode (LED -LEDn 1) is presented in accordance with the control .

그러므로 사용자는 발광다이오드(LED1-LEDn)의 구동되는 레벨을 보고 IDENT 조정 전압 최대한으로 높여 주어 전체 발광다이오드(LED1-LEDn)를 점등시켜 주게 된다.Therefore, the user is granted subject to see the level at which the driving of the light emitting diode (LED 1 -LEDn) increases as the adjustment voltage IDENT possible to light the entire light emitting diode (LED 1 -LEDn).

이같이 발광다이오드(LED1-LEDn)가 전부 점등시키도록 IDENT 조정 전압이 조정되었을때가 SECAM 방식의 TV에서 칼라 신호가 최대로 잘 나오게 된다.In this way, when the IDENT adjustment voltage is adjusted so that all the light emitting diodes (LED 1 -LEDn) are turned on, the color signal is best displayed in the SECAM type TV.

이상에서와 같이 본 고안은 SECAM 방식의 TV에서 IDENT 조정 전압을 미리 설정된 조정 전압레벨과 그 레벨 차이로 차동증폭시켜 발광다이오드의 구동을 제어하게 하므로써 발광다이오드의 구동을 보고 IDENT 전압을 칼라 신호가 가장 잘 나오게 조정할 수 있으며 또한 디지털이나 아니로그 방식의 전압 표시에 비해 사용자가 간단히 사용할 수 있는 효과가 있는 것이다.As described above, the present invention differentially amplifies the IDENT adjustment voltage to a preset adjustment voltage level and the level difference in a SECAM type TV so as to control the driving of the light emitting diodes. It can be easily adjusted and has a simple effect for the user compared to digital or an analog voltage display.
