Description
본 발명은 전압,전류 측정기에 관한 것으로서, 보다 상세하게는 특정 측정부위간에 인가되는 전압 또는 전류의 세기를 간이로 기대치에 맞도록 설정하여 시각적으로 확인할 수 있는 전압,전류 측정기에 관한 것이다.The present invention relates to a voltage and current meter, and more particularly, to a voltage and current meter that can be visually confirmed by setting the intensity of a voltage or current applied between specific measurement sites to easily meet expectations.
반도체 제조설비를 이루는 구성단위 별로 각기 다른 기능을 수행하는 인쇄회로기판(PCB : Printed Circuit Board)들이 전기적으로 연결되어 제조설비가 작동된다. 그런데, 인쇄회로기판에 실장되는 소자들 중 그 수명 또는 외부의 영향으로 이상이 발생되면 기능적인 오동작이 발생한다. 이러한 기능적인 오동작을 판단하거나, 정상상태에서 소자들에 인가되는 전압,전류를 측정하는 수단을 이용해 정상여부를 판단해야 한다.Printed Circuit Boards (PCBs), which perform different functions for each structural unit of a semiconductor manufacturing facility, are electrically connected to each other to operate the manufacturing facility. However, when an abnormality occurs due to the lifespan or external influence among the elements mounted on the printed circuit board, a functional malfunction occurs. Such functional malfunction should be determined or normalized by means of measuring the voltage and current applied to the devices in the normal state.
종래의 프랜트 배선 회로용 기판에 실장된 소자와 같은 구성부품을 점검하기 위한 방법으로는, 디지털 전압계(Digital Voltage Meter)를 이용하여 전압 또는 전류를 측정하여 정상적인 경우에서의 설정치와 그 크기를 비교하여, 정상여부를 판단하였다. 그리고, 오실로스코프(Oscilloscope)를 이용하여 점검할 수도 있는데, 오실로스코프로 특정 측정부위를 설정하여 파형의 피크(Peak)전압과 전류 등을 측정하였다.As a method for checking a component such as an element mounted on a conventional plant wiring circuit board, a voltage or a current is measured by using a digital voltage meter to compare the set value and the size in a normal case. It was judged normal. In addition, an oscilloscope may be used for checking, and a specific measurement region is set with an oscilloscope to measure peak voltage and current of a waveform.
전술한 디지털 전압계나 오실로스코프를 이용한 측정방법에 의하면 크기를 비교적 정확한 수치의 형태로 확인할 수 있었다. 그러나, 각 측정기를 사용하기 전에 기본적인 사용방법을 숙지해야 하거나, 이를 위한 교육이 필요하며, 촬상관에 나타난 파형 및 데이터를 판독하고, 이를 설정치와 비교해야 하는 번거로움이 있었다.According to the measurement method using the above-described digital voltmeter or oscilloscope, the size could be confirmed in the form of a relatively accurate value. However, before using each measuring instrument, it is necessary to know the basic method of use or training for this, and it is cumbersome to read the waveform and data displayed on the imager and compare it with the set value.
전술한 바와 같이 종래의 방법에 의한 전압,전류의 측정은 측정치를 판독하고, 정상적인 때의 설정치와 비교해야 하며, 사전에 사용방법을 숙지해야 하는 등의 문제점이 있었다.As described above, the measurement of the voltage and current by the conventional method has a problem such as reading the measured value, comparing it with a set value at a normal time, and learning how to use it in advance.
본 발명의 목적은, 누구든지 사용하기 쉽게 하고, 측정치 판독이 별도로 필요없으며, 전압,전류를 간이로 측정하여 시각적으로 확인할 수 있는 전압,전류 측정기를 제공하는 데 있다.It is an object of the present invention to provide a voltage and current measuring device that is easy to use for anyone, and does not need to read the measured value separately and can visually check the voltage and current by simply measuring it.

상기 가변수단으로는 가변저항을 사용하며, 상기 표시수단으로는 발광다이오드를 사용한다.A variable resistor is used as the variable means, and a light emitting diode is used as the display means.
상기 표시수단에 확대 렌즈를 설치할 수 있다.An enlarged lens may be installed on the display means.
이하, 본 발명의 구체적인 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도1은 본 발명의 일 실시예에 따른 전압,전류 측정기의 사시도이다.1 is a perspective view of a voltage and current meter according to an embodiment of the present invention.
도2는 도1의 접속단자에 피계측기를 연결하여 측정이 이루어지는 사용례를 간략하게 나타내는 회로도이다.FIG. 2 is a circuit diagram briefly illustrating a use example in which measurement is performed by connecting an instrument to the connection terminal of FIG. 1.
도1에서 보는 바와 같이 전압,전류 측정기(2)는 소정 범위의 저항값을 가변시키는 가변저항(10), 상기 가변저항(10)에 연결되고, 전원이 인가되는 여부에 따라 표시상태를 다르게 하는 발광다이오드(12) 및 상기 가변저항(10)과 상기 발광다이오드(12)에 각각 연결된 접속단자(14)들을 포함하여 이루어진다.As shown in FIG. 1, the voltage and current measuring device 2 is connected to a variable resistor 10 for varying a resistance value within a predetermined range and the variable resistor 10, and changes the display state according to whether power is applied. And a connection terminal 14 connected to the light emitting diode 12 and the variable resistor 10 and the light emitting diode 12, respectively.
상기 발광다이오드(12)에 확대렌즈(도시하지 않음)를 설치하여 상기 발광다이오드(12)의 발광상태를 크게 보이게 할 수 있다.An enlarged lens (not shown) may be installed on the light emitting diodes 12 to make the light emitting state of the light emitting diodes 12 large.
도2에서 보는 바와 같이 피계측기(16) 또는 소자(도시하지 않음)와 소자간에 접속단자를 접속하여 그들에 인가되는 전압이나, 전류의 세기에 따라 발광다이오드(12)가 발광 또는 소광된다. 상기 발광 또는 소광은 인가되는 전압 또는 전류의 세기를 정상적인 경우에서의 값이 되도록 가변저항(10)을 조작하여 판단할 수 있다. 상기 피계측기(16)는 인쇄회로기판으로써 기판에 실장된 소자들을 측정한다.As shown in Fig. 2, the light emitting diode 12 emits light or quenches in accordance with the voltage or current applied to the measurement terminal 16 or the device (not shown) and the connection terminal. The light emission or extinction may be determined by manipulating the variable resistor 10 so that the intensity of the applied voltage or current becomes a value in a normal case. The instrument 16 measures elements mounted on a substrate as a printed circuit board.
소자간의 정상적인 전압차에서 발광다이오드(12)가 온(ON)될 수 있는 가변저항(10)의 저항값을 설정했을 때 전압,전류 측정기(2)에 의한 판단은, 발광다이오드(12)가 온(ON)되면, 소자에 이상이 없음이 판단된다. 그리고, 발광다이오드(12)가 오프(OFF)되면 소자에 이상이 있음을 판단할 수 있다.When the resistance value of the variable resistor 10 which can turn on the light emitting diodes 12 is set at a normal voltage difference between the elements, the determination by the voltage and current measuring device 2 is that the light emitting diodes 12 are turned on. If it is (ON), it is determined that there is no abnormality in the element. When the light emitting diodes 12 are turned off, it may be determined that there is an error in the device.
설정전압, 전류의 크기에 따라 전압,전류 측정기(2)의 측정범위를 조정할 때는 가변저항(10)을 이용하여 저항값의 설정치를 변경하여 이루어진다. 상기 가변저항(10)의 가변되는 저항치는 측정하고자 하는 전압,전류에 따라 1㏀, 100㏀ 등으로 제작할 수 있고, 가변저항(10)의 크기에 따라 발광다이오드(12)의 정격전압도 가변된다.When adjusting the measurement range of the voltage and current measuring device 2 according to the set voltage and the magnitude of the current, the variable resistor 10 is used to change the set value of the resistance value. The variable resistance value of the variable resistor 10 may be manufactured to 1 kW, 100 kW, etc. according to the voltage and current to be measured, and the rated voltage of the light emitting diode 12 also varies according to the size of the variable resistor 10. .
전술한 바와 같이 본 발명에 따른 실시예에 의하면, 측정치 그대로 활용할 수 있으며, 사용하기가 쉬운 이점이 있다.As described above, according to the embodiment of the present invention, the measured value can be utilized as it is, and there is an advantage that it is easy to use.
따라서, 본 발명에 의하면 누구든지 사용하기 쉽게 하고, 측정치 판독이 별도로 필요없으며, 전압,전류를 간이로 측정하여 시각적으로 확인할 수 있는 효과가 있다.Therefore, according to the present invention, it is easy to use for anyone, and there is no need to read the measured value separately, and there is an effect that can be visually confirmed by simply measuring the voltage and current.
이상에서 본 발명은 기재된 구체예에 대해서만 상세히 설명되었지만 본 발명의 기술사상 범위 내에서 다양한 변형 및 수정이 가능함은 당업자에게 있어서 명백한 것이며, 이러한 변형 및 수정이 첨부된 특허청구범위에 속함은 당연한 것이다.Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
