Abstract

본 발명은 광-케이블 TV 가입자 장치를 이루는 디지탈 보드 부분과, 아날로그 보드 부분에 공급되는 전원 블럭을 통합하고, 이 통합된 블럭을 개폐소자를 사용하여 제어하므로써, 하나의 전원블럭으로 두개의 보드에 제공되는 전원을 제어 공급하는 광-케이블 TV 가입자 장치에서 전원 공급방법에 관한 것으로, 릴레이 등의 개폐소자를 사용하므로써, 효율성이 높으며, 사용부품이 적게 들어 경제적일 뿐만 아니라, 신뢰성을 향상시키는 잇점이 있다.The present invention integrates a digital board portion constituting an optical-cable TV subscriber device with a power block supplied to an analog board portion, and controls the integrated block by using an opening and closing element, thereby providing two boards with one power block. The present invention relates to a power supply method for an optical-cable TV subscriber device that controls and provides a power supply. The use of a switching element such as a relay provides high efficiency, economical efficiency due to fewer components, and improved reliability. have.

Description

광-케이블 TV 가입자 장치에서 전원 공급 방법How to Power on an Optical-Cable TV Subscriber Device

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명에 의한 광-케이블 TV 가입자 장치 전원 공급 회로이다.2 is an optical-cable TV subscriber device power supply circuit according to the present invention.

Claims (1)

광-케이블 TV 가입자 장치 내의 디지탈 보드와, 아날로그 보드에 전원 공급 시, 디지탈 보드 전원공급 방식과, 아날로그 보드 전원공급 방식을 사용하여 전원을 분리 공급하는 전원 공급 방법에 있어서, 분리된 디지탈 전원 공급부와, 아날로그 전원 공급부를 하나의 전원 공급부로 통합시키고; 상기 통합된 전원 공급부에서 디지탈 전원 공급은 디지탈 보드 전원 공급방식으로 전원을 공급하며; 상기 아날로그 보드 전원 공급은 디지탈 전원 공급 출력단과 아날로그 보드 전원입력단 사이에 개폐소자를 연결시켜, 상기 개폐소자의 개폐동작에 따라 전원이 공급되도록 하는 것을 특징으로 하는 광-케이블 TV 가입자 장치에서 전원 공급 방법.In the power supply method for supplying power separately using a digital board in an optical-cable TV subscriber device, a digital board power supply method, and an analog board power supply method when power is supplied to an analog board, a separate digital power supply unit and Integrating the analog power supply into a single power supply; The digital power supply in the integrated power supply supplies power in a digital board power supply method; The analog board power supply is connected to a switch between the digital power supply output terminal and the analog board power input terminal, so that the power is supplied according to the opening and closing operation of the switching element power supply method in the optical-cable TV subscriber device. . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
