Abstract

본 발명은 일정지역에서 라디오의 수신가능한 모든 방송채널을 미리 선별하여 메모리시키는 브리셋메모리(preset memory)기능에 의해 선국된 강전계의 방송채널이 타지역으로 이동하였을때 약전계로 변환되었을 경우 자동으로 이를 감지하여 강전계의 방송채널만을 다시 선별하여 메모리시키도록 하는 약전계 방송채널의 프리셋 메모리 자동선국방법에 관한 것으로, 카오디오를 구성하는 AM/FM튜너의 강전계 방송채널이 자동차의 장거리주행에 의해 약전계 방송채널로 변환되면 자동으로 메모리스캔기능이 동작하여 전지역에서 메모리된 강전계및 약전계의 방송채널을 모두 지우고, 현재 주행지역에서의 강전계방송채널로 교체하여 메모리부에 저장하므로써 장거리 주행시 AM/FM튜너를 수신할 때에 수신상태가 나쁘게 되면 자동으로 다른 주파수대로 전환하게 되므로써 항상 양호한 상태의 방송을 수신할 수 있게 된다.According to the present invention, when a broadcast channel of a tuned electric field is shifted to a weak electric field by a preset memory function that selects and memorizes all broadcastable broadcast channels of a radio in a predetermined region, the present invention is automatically converted into a weak electric field. The present invention relates to a preset memory automatic tuning method of a weak electric field broadcasting channel which detects this and selects and stores only a strong electric field broadcasting channel. A strong electric field broadcasting channel of an AM / FM tuner constituting a car audio is used for long distance driving of a car. By converting into weak electric field broadcasting channel, memory scan function operates automatically and erases all the strong electric field and weak electric field broadcasting channel memorized in all regions, and replaces with the strong electric field broadcasting channel in the current driving area and saves it in the memory section. When receiving AM / FM tuner while driving, if the reception becomes bad, Doemeurosseo always be able to receive the broadcast is in good condition.

Description

방송채널의 프리셋 메모리 자동선국방법Automatic tuning of preset memory of broadcasting channel

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (1)

카오디오의 AM/FM튜너가 온절환되어 동작중인가를 판단하는 제1단계(S1)와, 상기 단계(S1)에서 AM/FM튜너가 온상태이면 프리셋메모리기능에 의해 현재 메모리부에 메모리된 방송채널중 약전계가 있는가를 판단하는 제2단계(S2)와, 상기 제2단계(S2)에서 메모리부에 강진계로 메모리된 방송채널이 약전계로 변환되었으면 프리셋스캔기능을 동작시키는 제3단계(S3)와, 상기 단계(S3)다음에 자동 프리셋메모리기능에 의해 현재 메모리부에 저장된 방송채널을 현재 주행지역의 강전계방송채널로 모두 교체하는 제4단계(S4)로 실행되는 것을 특징으로하는 방송채널의 프리셋 메모리 자동선국방법.The first step (S1) of judging whether the AM / FM tuner of the car audio is switched on and operating, and if the AM / FM tuner is turned on in the step (S1) is stored in the current memory unit by the preset memory function A second step (S2) of determining whether there is a weak electric field among the broadcast channels; and a third step (S3) of operating the preset scan function when the broadcast channel memorized in the memory unit in the second step (S2) is converted into a weak electric field (S3). And a fourth step S4 of replacing the broadcasting channel stored in the current memory unit with the strong electric field broadcasting channel of the current driving region by the automatic preset memory function after the step S3. Automatic preset tuning of channels. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
