Abstract
본 발명은 자동차에 설치되는 카오디오의 AM/FM튜너를 이용하여 주행중 일정방송채널을 선택하여 청취할 때에 양호한 상태를 갖는 강전계의 방송채널을 수신하던 상태에서 장거리 주행에 의한 수신지역의 이동에 의해 수신 상태가 불량한 약전계의 방송채널로 전환될 때에 이를 감지하여 청취자에게 현재 수신중인 방송채널이 약전계지역임을 신속하게 알려줄 수 있는 약전계지역 표시장치에 관한 것으로, 일정지역에서 수신중이던 강전계의 방송채널이 장거리 주행에 따른 지역이동으로 약전계의 방송채널로 전환되면 마이컴에서 이를 감지하여 디스프레이부에 약전계에 해당하는 일정표식을 나타내어 청취자로 하여금 신속하게 방송수신상태를 파악하여 다른 강전계의 방송채널로 재선국할 수 있도록 함으로써 항상 원활한 방송수신을 할 수 있도록 하는 효과가 있다.According to the present invention, when a certain broadcasting channel is selected and listened to while using a car audio AM / FM tuner installed in a vehicle, the present invention is used to move a reception area by long distance driving while receiving a broadcasting channel of a strong electric field having a good condition. The present invention relates to a weak electric field display device that can detect when a signal channel is switched to a broadcast channel having a poor reception state and quickly notify the listener that the broadcast channel being received is a weak field. When the broadcasting channel is changed to the broadcasting channel of the weak electric field due to local movement according to the long distance driving, the microcomputer detects this and displays the schedule marker corresponding to the weak electric field on the display unit. You can always receive smooth broadcasting by retuning to broadcasting channels. This has the effect of.
