Abstract

본 발명은 카오디오용 자동 선국 메모리장치를 이용한 자동 선국방법에 관한 것으로, 지역별 오토메모리키이신호가 설정되었을 경우 현재 수신되고 있는 방송의 수신감도가 낮은지를 체킹하는 수신감도 체킹단계와, 상기 수신감도 체킹단계 후에 판단한 결과 그 체킹수신 감도가 일정시간 지속적으로 좋지 않을 경우는 라디오 방송이 아닌 일정신호음을 출력하는 지속시간 판단단계와, 이 지속시간 판단단계 후에 현 밴드에서 기메모리되어 있는 방송주파수를 체킹하는 밴드체킹 단계와, 이 밴드체킹 단계후에 현 지역의 방송주파수를 검색하여 자동적으로 선국메모리하는 자동 선국 메모리단계로 이루어져 감지상태에 따라 자동적으로 최적 수신모드를 선택하도록 하므로써, 지역별 방송 주파수에 관계없이 항상 최적의 선국상태를 유지할 수 있어 수신감도의 최적성을 증가시킬 수 있음을 물론 운전자가 별도의 선국 동작을 수행하지 않아도 되므로 이에 따라 사용의 편리성도 향상되게 된다.The present invention relates to an automatic tuning method using an auto tuning memory device for car audio, comprising: a reception sensitivity checking step of checking whether a reception sensitivity of a currently received broadcast is low when an auto memory key signal for each region is set; If it is determined after the checking step that the receiving sensitivity is not good for a certain period of time, it is a duration judgment step of outputting a constant beep instead of radio broadcasting, and after this duration judgment step, checking the broadcasting frequencies stored in the current band. It consists of a band checking step and an automatic tuning memory step that searches for and tunes the broadcasting frequency of the current region automatically after this band checking step so that the optimum reception mode is automatically selected according to the detection state, regardless of the broadcasting frequencies of each region. I can always maintain the optimal tuning state That can increase the sensitivity as well as the best of the new driver it does not need to perform additional tuning operation since thereby be improved ease of use saints.

지역별 오토메모리 키이신호가 설정되었을 경우 현재 수신되고 있는 방송의 수신감도가 낮은지를 체킹하는 수신감도 체킹단계와, 상기 수신감도 체킹단계 후에 판단한 결과 그 체킹수신감도가 일정시간 지속적으로 좋지 않을 경우는 라디오 방송이 아닌 일정신호음을 출력하는 지속시간 판단단계와, 이 지속시간 판단단계 후에 현 밴드에서 기메모리되어 있는 방송주파수를 체킹하는 밴드체킹단계와, 이 밴드체킹단계 후에 현 지역의 방송주파수를 검색하여 자동적으로 선국메모리하는자동선국 메모리 단계로 이루어진 것을 특징으로 하는 카오디오용 자동 선국 메모리 장치를 이용한 자동 선국방법.When the auto memory key signal for each region is set, a reception sensitivity checking step of checking whether the reception sensitivity of the currently received broadcast is low, and after the reception sensitivity checking step is determined, if the checking reception sensitivity is not good for a predetermined time, A duration determination step of outputting a constant beep sound, not a broadcast; a band checking step of checking a broadcast frequency memorized in the current band after the duration determination step; and searching for a broadcasting frequency of the current region after the band checking step. An automatic tuning method using an automatic tuning memory device for car audio, characterized in that the automatic tuning memory step of automatically tuning memory. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
