Description
본 발명은 전자식 자동전원 스위치에 관한 것으로 오디오 신호를 검출하여The present invention relates to an electronic automatic power switch to detect an audio signal
직류전원을 온 오프시키는 전자식 자동 스위치에 관한 것이다.An electronic automatic switch for turning on or off a direct current power source.
컴퓨터용 증폭기나 컴퓨터용 주변기기의 오디오 신호 유무를 판단하여Determining the audio signal of computer amplifier or computer peripheral
자동으로 전원을 켜고 끄는 장치이다.It is a device that automatically turns on and off.
종래에는 컴퓨터의 전원을 꺼도 외부장치의 전원이 별도의 스위치를 끄기Conventionally, even if the computer is turned off, the external device power is switched off.
전까지는 계속 전원이 켜있기 때문에 전류의 소모가 발생되었고 전원을Until the power is on until the current is consumed,
직접 꺼야되는 불편이 발생되었다.Discomfort caused to turn it off directly.
따라서, 본 발명은 이러한 종래의 문제점을 해결하기 위해 안출된 것으로써Accordingly, the present invention has been made to solve such a conventional problem.
그 목적은 전류용량이 낮은 부분은 구동부분을 반도체를 사용하고 전류용량The purpose is to use the semiconductor part as the driving part for the low current capacity
이 높은 부분은 구동 부분을 릴레이를 사용하여 전류의 소모를 줄이고자This high part uses the driving part to reduce current consumption
함과 사용의 편리함을 제공하고자 하는 것이다..To provide convenience and ease of use.
도1은 본 발명에 따른 전자식 자동전원 스위치의 개략적인 블럭구성도,1 is a schematic block diagram of an electronic automatic power switch according to the present invention;
도2는 본 발명에 따른 자동전원 스위치의 상세회로도이다.2 is a detailed circuit diagram of an automatic power switch according to the present invention.
이러한 목적을 실현하기 위하여 본 발명에 따른 전자식 자동전원 장치는In order to realize the above object, the electronic automatic power supply apparatus according to the present invention
증폭기 A1에서 오디오 신호를 증폭하는 증폭부와 오디오신호를 D1The amplifier A1 amplifies the audio signal and the audio signal D1.
(다이오드)을 통해 정류하는 정류부(11)와 A2의 증폭기에서 비교검출하는Comparative detection by the rectifier 11 rectifying through (diode) and the amplifier of A2
비교부(12)와 R8을 통해 Q1과 Q2를 동작시키는 전자스위치 동작부(13)로To the electronic switch operation unit 13 for operating Q1 and Q2 through the comparison unit 12 and R8
구성된다.It is composed.
이상에서 설명한 바와같이 본 발명에 따른 자동 전원장치는 전류의 소모량을As described above, the automatic power supply apparatus according to the present invention reduces the current consumption.
최대한 줄여주는 효과가 있고 주변기기를 사용하기 편리하다.It has the effect of reducing as much as possible and is convenient to use peripherals.
