초대형 냉장고의 고내등 제어 방법How to control the interior light of a very large refrigerator

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

제1도는 본 발명의 1실시 예의회로도, 제2도는 본 발명의 1실시예의 동작을 설명하기 위한 플로우챠트, 제3도는 본 발명에서 조도에 대한 광센서의 저항변화의 곡선도.1 is a circuit diagram of one embodiment of the present invention, FIG. 2 is a flowchart illustrating the operation of one embodiment of the present invention, and FIG. 3 is a curve diagram of the resistance change of an optical sensor with respect to illuminance in the present invention.

마이컴(1)에서 입력단자(Ⅰ1)에 연결된 광센서부(2)로부터 입력되는 전압을 아날로그 값으로 읽어들여 디지털 값으로 변환시킨 다음 설정값(C0)보다 검출된 값(C)이 작은가를 검출하여 검출값(C)이 작으면 출력단자(O1)신호를 '하이'로 하여 고내등(LP) 제어용 릴레이(RL1)를 구동시켜 고내등 (LP)을 점등시키되, 설정값(C0)보사 크거나 같게 되면 출력단자(O1) 신호를 '로우'로 하여 고내등(LP)을 소등시키는 과정을 수행하도록 하여서된 초대형 냉장고의 고내등 제어 방법.The voltage input from the optical sensor unit 2 connected to the input terminal I 1 in the microcomputer 1 is read as an analog value, converted into a digital value, and the detected value C is smaller than the set value C 0 . If the detection value (C) is small and the output value (O 1 ) signal is 'high', the high light (LP) control relay (RL 1 ) is driven to turn on the high light (LP), but the set value (C 0) ) If the greater than or equal to high output lamp (O 1 ) signal to the 'low' to perform the process of extinguishing the high light (LP) high internal lamp control method. 제1항에 있어서, 상기 마이컴(1)에서 입력단자(Ⅰ1)에 연결된 고내등 제어용 스위칭 입력부(4)의 출력이 '로우'인가를 검출하여 '로우'가 아니면 재차 '로우'인가를 검출하되, '로우'이면 출력단자(O1)신호가 '하이'로 유지되고 있는지를 검출하여 '하이'가 아니면 출력단자(O1)를 '하이'로 하고 재차 입력단자(Ⅰ1)가 '로우'인가를 검출하는 과정으로 되돌아가는 제1과정과; 상기 제1과정에서 입력단자(Ⅰ1)에 인가된 신호가 재차 '로우'이면 소정시간(T0)이 '0'인가를 검출하여 '0'이면 출력단자(O1)를 '로우'로 하고 소정시간(T0)을 재차 입력시킨후 종료하되 입력단자(Ⅰ1)가 '로우'가 아니면 곧 바로 종료하고, 소정시간(T0)이 '0'이 아니면 소정시간(T0)을 감소시킨후 종료하며, 제1과정에서 출력단자(O1)가 '하이'이면 출력단자(O1)를 '로우'로 하여 종료하는 제2과정을 수행하도록 하여서된 초대형 냉장고의 고내등 제어 방법.The method of claim 1, wherein the microcomputer 1 detects whether the output of the high-light control switching input unit 4 connected to the input terminal I 1 is 'low' and again detects whether the output is 'low'. , If it is' low ', it detects whether the output terminal (O 1 ) signal is kept' high '. If it is not' high ', the output terminal (O 1 ) is set to'high'and again the input terminal (Ⅰ 1 ) is set to 'low'. A first step of returning to a process of detecting authorization; If the signal applied to the input terminal I 1 in the first process is 'low' again, it is detected whether the predetermined time T 0 is '0'. If the signal is '0', the output terminal O 1 is changed to 'low'. After inputting the predetermined time (T 0 ) again, it ends. But if the input terminal (I 1 ) is not 'low', it ends immediately. If the predetermined time (T 0 ) is not '0', the predetermined time (T 0 ) after reducing end, and an output terminal (O 1) it is "high" if the output terminal (O 1) a method gonaedeung control of very large refrigerator hayeoseo a to carry out the second process to be shut down to "low" from the first process. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
