Abstract
본 발명은 세탁기의 마이콤에 입력되는 전원주파수를 정확하게 감지할 수 있도록 한 세탁기의 입력주파수감지방법에 관한 것으로, 본 발명은 입력되는 전원전압에 대하여 인터럽트신호를 체크하는 단계와, 상기 단계에서 체크되는 인터럽트신호를 감지 판단하여 인터럽트신호가 감지 되었으면 타이머를 카운트하는 단계와, 상기 단계에서 타이머를 카운트한 상태에서 다음 인터럽트신호를 체크하여, 인터럽트신호가 감지되면 타이머카운트를 정지하는 단계와, 상기 단계에서 타이머로 카운트된 시간에 의하여 해당되는 전원주파수를 판단하는 단계와, 상기 단계에서 해당되는 전원주파수가 없을 경우, 입력 전원주파수에 이상이 있음을 표시하는 단계로 이루어짐을 특징으로 한다.The present invention relates to a method for detecting an input frequency of a washing machine to accurately detect a power frequency input to a microcomputer of a washing machine. The present invention includes the steps of checking an interrupt signal with respect to an input power voltage, Counting the timer when the interrupt signal is detected by detecting the interrupt signal; checking the next interrupt signal while the timer is counted in the step; stopping the timer count when the interrupt signal is detected; Determining a corresponding power frequency by a time counted by a timer; and in the case where there is no corresponding power frequency in the step, indicating that there is an error in the input power frequency.
