Abstract
본 발명은 접근신관내의 시한기능을 가진 타이머에 있어 가변저항(VR) 분배에 의한 전압으로 시간이 설정되고 원칩프로세서는 구동클럭에 의해 카운트된 시간과 설정시간을 비교하여 전력소모가 많은 전자부(RF)의 구동전원을 제어하기 위한 가변저항(VR)을 이용한 디지탈 타이머에 관한 것으로, 전원부(15)에서 정전압이 인가되면 발진기(12)의 발진클럭과 제어 프로그램에 의해 카운트 동작을 실행하여 파워스위치제어회로(16)로 파워스위치(SW1) 제어신호를 송출하는 원칩프로세서(10)가 구비된 접근신관의 타이머에 있어서, 상기 타이머에 가변저항(VR)의 분배에 의한 분배전압으로 일정시간(예 : 0~199Sec)의 카운트 시간을 설정하는 시간설정부(13)와 상기 시간 설정부(13)에서 설정된 아날로그 신호를 디지탈 신호로 변환하는 A/D변환기(11)를 포함하여 정확한 시한기능을 갖도록 한 것이다.According to the present invention, the time is set by the voltage of the variable resistor (VR) distribution in the timer with the time function in the access fuse, and the one-chip processor compares the time counted by the driving clock with the set time and consumes a lot of power. A digital timer using a variable resistor (VR) for controlling a driving power of RF), and when a constant voltage is applied from the power supply unit 15, the oscillation clock and the control program of the oscillator 12 execute a count operation to execute a power switch. In a timer of an access fuse equipped with a one-chip processor (10) for transmitting a power switch (SW1) control signal to the control circuit (16), a predetermined time (eg It includes a time setting unit 13 for setting the count time of 0 ~ 199Sec and an A / D converter 11 for converting the analog signal set by the time setting unit 13 into a digital signal. It has a time function.
