Description

전압레벨을 표시하는 전원공급장치{POWER SUPPLY DEVICE FOR DISPLYING VOLTAGE LEVEL}Power supply displaying voltage level {POWER SUPPLY DEVICE FOR DISPLYING VOLTAGE LEVEL}

본 발명은 반도체 제조설비의 전원공급장치에 관한 것으로, 특히 반도체 제조설비의 하드디크 드라이버를 구동하기 위한 전압레벨을 표시하는 전원공급장치에 에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply for a semiconductor manufacturing facility, and more particularly to a power supply for displaying a voltage level for driving a hard disk driver of a semiconductor manufacturing facility.

일반적으로 반도체 제조설비에는 각종 공정을 제어하는 컴퓨터가 구비되어 있으며, 이러한 컴퓨터에는 하드디스크가 내장되어 각종 공정 데이터를 저장하고 있고, 그 저장된 공정데이터를 이용하여 각종 공정을 진행하도록 하고 있다. 그런데 하드디스크는 DC 전원공급장치(DC POWER SUPPLY)로부터 출력되는 전원을 공급받는 하드디스크 드라이버에 의해 구동된다. In general, a semiconductor manufacturing facility includes a computer for controlling various processes. A hard disk is built into the computer to store various process data, and various processes are performed using the stored process data. However, the hard disk is driven by a hard disk driver that receives the power output from the DC power supply.

이러한 하드디스크 드라이버는 DC전원공급장치로부터 전원을 공급받아 하드디스크를 구동하게 되는데, DC전원공급장치로부터 출력되는 전압이 설정된 전압(SPEC VOLTAGE)을 벗어나면 반도체 제조설비가 오프되는 현상이 발생한다.The hard disk driver receives power from the DC power supply to drive the hard disk. When the voltage output from the DC power supply is out of the set voltage SPEC VOLTAGE, the semiconductor manufacturing equipment is turned off.

그런데 종래에는 DC 전원공급장치(POWER SUPPLY)는 전압을 디지털 볼트 미터(Digital Voltage Meter)로 체크하지 않으면 전압을 확인할 수 없기 때문에 전압이 정상적으로 공급되고 있는지 인지할 수 없기 때문에 설비가 중단되고 나서 조치를 취하게 되므로 공정중단 사고를 미연에 방지할 수 없어 막대한 피해가 발생하는 문제가 있었다. However, conventionally, the power supply (POWER SUPPLY) cannot check the voltage unless the voltage is checked with a digital voltage meter, so it is impossible to know whether the voltage is being supplied normally. Since the process can not be prevented in advance, there is a problem that enormous damage occurs.

따라서 본 발명의 목적은 상기와 같은 문제를 해결하기 위해 전원공급장치로부터 출력되는 전압레벨을 표시하여 하드디스크 드라이버로 정상전원이 공급되고 있는지 확인할 수 있는 전원공급장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a power supply that can determine whether the normal power is supplied to the hard disk driver by displaying the voltage level output from the power supply to solve the above problems.

본 발명의 다른 목적은 하드디스클 드라이버로 인가되는 전압레벨을 감시하여 설정된 전압을 벗어날 경우 경보를 발생하는 전원공급장치를 제공함에 있다.Another object of the present invention is to provide a power supply device that monitors the voltage level applied to the hard disk driver and generates an alarm when it is out of the set voltage.

The voltage level display device of the power supply device of the present invention for achieving the above object includes a DC power supply device for outputting a DC voltage, a voltage detector for detecting a plurality of DC voltage levels output from the DC power supply device, An A / D converter which converts and outputs the voltages detected by the voltage detector into a digital signal, and controls to receive and display the converted digital signal from the A / D converter, and alarms when the voltage is out of the set voltage in comparison with a preset voltage. And a voltage display unit displaying a voltage level under the control of the controller.
