Abstract
본 발명은 자동전원 차단장치에 관한 것으로, 종래에는 마이크로컴퓨터의 제어출력에 의해 전원을 자동 차단시키는데는 문제가 없으나 자동전압 차단스위치가 구속되어 있으면 주기적으로 전원차단을 시도하는데 이때는 마이크로컴퓨터로 계속 전원이 공급되고 있어서 기기전체에 전원이 인가되어 있어 전력소비가 크고, 또한 마이크로컴퓨터 내부에선 주기적 신호를 출력하여야 하기때문에 계속적으로 시간계산을 하므로 마이크로컴퓨터 용량에 영향을 주게되는 문제점이 있었다. 따라서 종래의 문제점을 해결하기 위하여 본 발명은 1차적으로 자동전압차단스위치를 동작시키고 여기서 전원이 차단되지 않으면 자동전압차단스위치의 구속을 알려주는 표시를 하여주고 마이크로컴퓨터와 그 일부의 주변회로에 전원을 차단하여 일부분의 회로에만 전원을 공급하여 주어 주기적으로 전체적 전원차단을 함으로써 전력소모를 방지하도록 한 효과가 있다.The present invention relates to an automatic power shut-off device, and conventionally, there is no problem of automatically shutting off the power by the control output of the microcomputer, but if the automatic voltage cutoff switch is constrained, the power supply is periodically attempted. Since the power is supplied to the entire apparatus due to the supply of power, the power consumption is high, and since the periodic signal must be output inside the microcomputer, the time is continuously calculated, which affects the microcomputer capacity. Therefore, in order to solve the conventional problems, the present invention primarily operates the automatic voltage cut-off switch, and if the power is not cut off, an indication indicating the restraint of the automatic voltage cut-off switch is provided and power is supplied to the microcomputer and its peripheral circuits. Power is supplied to only a part of the circuits by blocking the power supply, thereby preventing power consumption by periodically shutting down the entire power supply.
