Abstract
본 발명은 카오디오를 구성하고 있는 AM/FM튜너를 이용하여 방송주파수를 스캐닝하여 메모리부에 일정 방송주파수를 메모리시킬때 전계강도의 기준레벨을 다단계로 구성시켜 스캐닝에 의해 선택되는 전계강도의 폭을 확장함으로써 낮은 전계강동의 방송주파수로부터 높은 전계강도의 방송주파수를 폭 넓게 메모리 시킬 수 있는 카오디오의 다단계 스캐닝시스템에 관한 것으로, 안테나를 통해 인가된 방송주파수의 전계강도가 마이컴에 접속된 모드입력버튼에 의해 설정된 저단계모드, 중단계모드 및 고단계모드중의 선택된 모드에 해당되는가를 판단하여 수신된 방송주파수의 전계강도가 선택된 모드에 해당되면 스캐닝동작부를 통해 스캐닝하여 해당되는 대체주파수를 체크하므로써 넓은 범위의 방송주파수를 스캐닝하여 대체주파수를 신속하게 체크하여 항상 원활한 방송을 수신할 수 있게 된다.The present invention uses the AM / FM tuner constituting the car audio to scan a broadcasting frequency to store a predetermined broadcasting frequency in a memory unit. It is a multi-stage scanning system of car audio that can store a wide range of high frequency strength broadcasting frequencies from low field strength broadcasting frequencies by extending the signal transmission mode.The field input of the broadcasting frequency applied through an antenna is connected to the microcomputer. If the electric field strength of the received broadcasting frequency corresponds to the selected mode, it checks the corresponding alternative frequency by scanning through the scanning operation unit. This allows you to scan a wide range of broadcast frequencies and quickly The size is always able to receive seamless broadcast.
