Abstract
본 발명은 퍼스널 컴퓨터에 부착하여 사용 가능한 주변기기의 동작 상태를 확인함으로써, 주변기기의 전원을 제어할 수 있는 컴퓨터의 전원 제어 장치에 관한 것으로, 일반적인 컴퓨터의 주변기기로서는 모니터, 플로피 디스크 드라이브(Floppy Disk Drive 이하 FDD라 칭함), 하드 디스크 드라이브(Hard Disk Drive 이하 HDD라 칭함), 프린터 등이 부착되어 사용가능하며, 각 주변기기들은 컴퓨터 본체와 독립적인 전원에 의하여 연결되어 있다.The present invention relates to a power supply control device for a computer that can control the power supply of a peripheral device by checking the operation state of the peripheral device that can be attached to a personal computer. FDD), hard disk drive (hereinafter referred to as HDD), printer, etc. can be attached and used, and each peripheral device is connected by a power source independent of the computer main body.
그러나, 이와같은 종래 컴퓨터의 전원 장치는 하나의 주변기기가 현재 동작중인 경우에는 전원이 공급되어야 하지만, 동작을 안하고 대기 상태에서도 전원이 공급되어 불필요한 전력을 소비하게 되고, 항상 전원이 공급되어 있는 상태이므로 이로인해 주변기기가 과열되어 제품의 성능 및 수명을 단축하게 되는 문제점이 있었다.However, the power supply of such a conventional computer power supply when one peripheral device is currently operating, but the power is supplied even in the standby state without operation and consumes unnecessary power, and is always powered. This causes a problem that the peripheral device is overheated, thereby reducing the performance and life of the product.
본 발명은 이와같은 종래의 문제점을 감안하여, 컴퓨터의 전원이 턴-온되어 있는 상태에서 타이머를 이용하여 주변기기들의 동작 상태를 확인하여, 일정시간동안 사용하지 않을 경우 타이머로부터 제어 신호를 발생하여, 주변기기에 인가되는 전원을 차단시킴으로써 전력소모를 감소시키고, 또 주변기기에 인가된 전원이 차단되었을 경우, 키보드나 마우스 등을 통해 주변기기 상태 입력이 들어오면 다시 주변기기에 인가된 전원을 연결함으로써, 자동으로 컴퓨터의 전원을 제어토록 한 것이다.In view of the conventional problems, the present invention checks the operation status of peripheral devices using a timer while the computer is turned on, and generates a control signal from the timer when not in use for a predetermined time. The power consumption is reduced by cutting off the power applied to the peripheral device. When the power supply to the peripheral device is cut off, when the peripheral status input comes through the keyboard or the mouse, the power is automatically connected to the peripheral device. To control the power supply.
