Claims (1)

초기화 단계에서 인터럽트를 이네이블 RAM을 클리어하고 3분 지연 비트를 세트시키므로 3분 지연을 수행하는 단계와, 3분지연을 판단하는 단계와, 3분 지연 후 압축기를 온하여서 3분 지연 비트를 클리어시켜주는 단계와, 압축기 온시에는 온비트를 클리어시키고 3분 지연을 시키고 3분 지연 카운터를 클리어시켜 주고 압축기 오프시에는 초기화 단계로넘어가는 단계와, 외부 구형파 펄스의 입력시마다 정전 카운터를 클리어시켜 정전을 감지하는 외부인터럽트 단계와, 외부발진회로의 신호를 분주하여 정전 카운터를 증가하여 3분 지연 비트를 셋트시키는 정전 카운터 검사를 위한 내부인터럽트단계들로 구성시킨 순간 정전감지 방법.In the initialization phase, the interrupt is cleared and the 3-minute delay bit is set, performing a 3-minute delay, determining the 3-minute delay, and turning on the compressor after the 3-minute delay clears the 3-minute delay bit. When the compressor is turned on, the on bit is cleared, the 3 minute delay is cleared, the 3 minute delay counter is cleared, and when the compressor is turned off, the step is passed to the initialization step. And an external interrupt step for detecting the external interrupt step and an internal interrupt step for checking the power failure counter by dividing the signal of the external oscillation circuit and increasing the power failure counter to set a 3-minute delay bit. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
