Claims (1)

충전용 백업 전지(10)를 구비하여 전원 백업을 제어하는 도난차량 추적 장치의 백업 전원제어 회로에 있어서, 상기 백업전지(10)의 전압 레벨을 검출하는 레벨검출부(20)와, 차량 전지 전원단(101)으로 부터 공급되는 주전원을 상기 레벨검출부(20)의 레벨 검출에 따른 전류를 가변시켜 상기 백업전지(10)를 충전하는 가변전류 충전부(30)와, 상기 차량 전지 전원단(101)으로 부터 공급되는 주전원의 전압을 디지탈 변환하는 A/D 변환기(40)와, 전원 제어단(102)의 스위치 입력에 의해 제어되며, 상기 A/D 변환기(40)의 출력 데이타 값에 의해 상기 주전원 전압 레벨을 감지하여 설정값까지 저하될씨 타이머 구동신호를 발생하고 영 레벨이 될씨 타이머 구동신호와동시에 경보신호(PIS) 발생하는 제어부(50)와, 상기 제어부(50)의 타이머 구동신호에 의해 트리거되어 설정시간동안 백업신호를 발생하는 타이머(60)와, 상기 타이머(60)의 백업 신호에 의해 상기 백업 전지(10)로 부터의 백업 전원공급을 단속하는 스위칭부(70)와, 상기 백업전원 공급시 백업 전원이 상기 차량전지 전원단(101)으로 방전되는 것을 방지하는 역전원 방지부(80)로 구성됨을 특징으로 하는 백업 전원 제어회로.In the backup power supply control circuit of an anti-theft vehicle tracking device including a backup battery 10 for controlling power backup, a level detector 20 for detecting a voltage level of the backup battery 10 and a vehicle battery power supply stage. The main power supplied from the 101 to the variable current charging unit 30 for charging the backup battery 10 by varying the current according to the level detection of the level detector 20, and the vehicle battery power supply 101. A / D converter 40 for digitally converting the voltage of the main power supplied from the power supply, and controlled by the switch input of the power control stage 102, the main power supply voltage by the output data value of the A / D converter 40 The control unit 50 detects a level and generates a seed timer driving signal to be lowered to a set value and generates an alarm signal PIS at the same time as the seed timer driving signal to be zero. When triggered and set A timer 60 generating a backup signal during the backup signal, a switching unit 70 intermitting the backup power supply from the backup battery 10 by the backup signal of the timer 60, and a backup at the backup power supply. Back-up power control circuit, characterized in that consisting of the reverse power protection unit 80 to prevent the power is discharged to the vehicle battery power terminal 101. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임※ Note: It is to be disclosed by the original application.
