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

제2도는 본 발명의 회로도.2 is a circuit diagram of the present invention.

Claims (2)

전원장치(1)와 배터리(2)는 전원전환장치(3)에 연결하고 전원전환장치(3)는 CMOS RAM 기억장치(4)를 통하여 중앙처리장치(6)와 메모리(7)에 연결하며 상기 전원장치(1)에 연결한 전원 리세트회로(5)는 상기 중앙처리장치(6)에 연결한 회로에 있어서, 상기 전원장치(1)에 정상전원감지회로(10)를 연결하여 상기 중앙처리장치 (6)에 접속하고 상기 전원전환장치(3)와 CMOS RAM 기억장치(4)에 배터리 수명 표시장치(20)를 연결하여 상기 전원장치(1)의 정상전원이 차단되었을 때 상기 정상전원감지장치(10)는 미리 차단전원을 감지하여 중앙처리장치(6)로 하여금 이에 해당하는 필요조치를 하도록 하는 것을 특징으로 하는 퍼스널 컴퓨터의 배터리 수명 표시 장치.The power supply unit 1 and the battery 2 are connected to the power switching unit 3, and the power switching unit 3 is connected to the central processing unit 6 and the memory 7 through the CMOS RAM storage unit 4, The power reset circuit 5 connected to the power supply device 1 is a circuit connected to the central processing unit 6, by connecting the normal power supply detection circuit 10 to the power supply device 1 to the center. The normal power supply when the normal power supply of the power supply device 1 is cut off by connecting to the processing device 6 and connecting the battery life display device 20 to the power switching device 3 and the CMOS RAM storage device 4. The sensing device (10) detects the interrupted power in advance so that the central processing unit (6) to take the necessary action corresponding thereto. 전원전환장치(3)는 정상전원과 배터리전원을 상황에 따라 번갈아가며 CMOS RAM 기억장치(4)와 배터리 수명 표시장치(20)에 항상 공급하고 중앙처리장치(6)는 상기 CMOS RAM 기억장치(4)의 현재시각과 정지시각을 읽어 1회 사용시간을 계산하고 누적 사용시각을 읽어 상기 1회 사용시간을 합쳐서 그 결과를 다시 누적 사용시간에 기억시켜며 이러한 정보를 배터리 수명 표시장치(20)에 전송하는 것을 특징으로 하는 퍼스널 컴퓨터의 배터리 수명 표시 장치.The power switching device 3 alternately supplies the normal power and the battery power to the CMOS RAM storage device 4 and the battery life display device 20 alternately according to the situation, and the central processing unit 6 supplies the CMOS RAM storage device ( Read the current time and stop time of 4) to calculate one time of use, and read the cumulative time of use, add the one time of use, and store the result again in the cumulative time of use. And a battery life display device for a personal computer. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
