Abstract
본 발명의 목적은 도어 비디오폰에 있어서, 도어 개방시에 모니터에 공급되는 전원을 제어하여 자동으로 모니터를 제어하도록 하는 도어 비디오폰의 도어개방시 모니터 자동 제어장치에 관한 것으로 이와같은 본 발명의 목적은 외부제어 신호에 따라 스위칭되는 도어 스위치와, 상기 도어스위치를 통한 전압에 의해 구동되어 도어를 개방하는 릴레이와, 상기 도어스위치를 통해 출력된 전압에 의해 모니터 제어신호를 출력하는 제1제어부와, 상기 제1제어부로 부터 출력된 제어신호에 의해 모니터 구동전원을 차단하여 모니터를 오프시키는 제2제어부를 구성함으로써 달성되어지는 것이다.An object of the present invention relates to an automatic door monitor of a door video phone when the door video phone is controlled to automatically control the monitor by controlling the power supplied to the monitor when the door is opened. A door switch switched according to an external control signal, a relay driven by a voltage through the door switch to open the door, a first control unit outputting a monitor control signal by a voltage output through the door switch, This is achieved by configuring a second control unit which turns off the monitor by cutting off the monitor driving power by the control signal output from the first control unit.
