Abstract

본 발명은 자동차에 구비되는 오디오 시스템에 관한 것으로, 자동 메모리 키의 원 터치(One Touch) 구동에 의하여 방송모드에 대하여 할당된 전대역의 채널주파수를 스캐닝한후 자동으로 저장되는 설정된 소정갯수의 방송채널이 주파수 대역의 크기에 따라 순차적으로 프리셋(Preset) 메모리에 저장되도록 하는 카 오디오 시스템의 방송채널 저장방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio system provided in a vehicle. The predetermined number of broadcast channels are automatically stored after scanning channel frequencies of all bands allocated for the broadcast mode by one touch driving of an automatic memory key. The present invention relates to a broadcasting channel storage method of a car audio system, which is sequentially stored in a preset memory according to the size of the frequency band.

본 발명은 방송모드에 따라 수신전계의 강도가 가장 양호한 임의의 갯수에 대한 채널 주파수의 자동 저장동작에서 프리셋 메모리의 어드레스 번지별로 주파수 자동 저장동작에서 프리셋 메모리의 어드레스 번지별로 주파수 대역이 낮은 채널이 순차적으로 저장되므로 운전자가 청취를 원하는 방송채널의 선택에 편리성을 제공한다.According to the present invention, a channel having a lower frequency band for each address address of a preset memory is sequentially sequenced by an address address of a preset memory in an automatic storage operation of a channel frequency for an arbitrary number of the best received electric field strengths according to a broadcasting mode. Because it is saved as, it provides convenience for selecting the broadcasting channel that the driver wants to listen to.

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

제 2 도는 본 발명에 따른 카 오디오 시스템의 방송채널 저장방법을 실현하기 위한 흐름도.2 is a flowchart for realizing a broadcasting channel storage method of a car audio system according to the present invention.

Claims (1)

오디오 시스템의 프리셑 채널 저장방법에 있어서, 저장을 원하는 방송모드와 프리셑 메모리 저장에 대한 선택신호를 검출하면 안테나를 통해 수신되는 전 대역의 채널 주파수에서 전계강도가 소정의 dB 이상인 채널주파수를 추출하는 제1과정과, 상기 제1과정에서 추출된 채널 주파수의 카운터를 증가시키면서 각각의 채널주파수에 대한 전계강도의 세기를 비교한후 프리셋 메모리의 어드레스 번지 갯수에 해당하는 소정갯수의 채널주파수만을 추출하는 제2과정과, 상기 제2과정에서 프리셑 메모리의 어드레스 번지 갯수에 해당하는 소정갯수의 채널 주파수가 추출되면 추출된 채널 주파수의 각각을 비교하여 주파수 대역이 낮은 순서로부터 순차적으로 분리하여 상기 프리셋 메모리의 어드레스 번지에 순차적으로 저장하는 제3과정과, 상기 제3과정에서 순차적으로 분리된 채널 주파수의 저장이 완료되면 키 선택부로부터 인가되는 신호에 따라 저장된 어드레스 번지와 채널 주파수를 표시부를 통해 순차적으로 스캐닝시키는 제4과정을 포함하는 것을 특징으로 하는 카 오디오 시스템의 방송채널 저장방법.In the method of storing a preset channel of an audio system, when a broadcast signal and a selection signal for storing a preset memory are desired to be stored, a channel frequency having an electric field strength of a predetermined dB or more is extracted from the channel frequencies of all bands received through the antenna. After comparing the first step to increase the counter of the channel frequency extracted in the first step to compare the strength of the electric field strength for each channel frequency and extracts only a predetermined number of channel frequencies corresponding to the number of address addresses of the preset memory And a predetermined number of channel frequencies corresponding to the number of address addresses of the preset memory in the second process are compared, and the respective preset channel frequencies are sequentially separated from the order in which the frequency bands are lowered. A third process of sequentially storing address addresses of the memory; And a fourth process of sequentially scanning the stored address and channel frequency through the display unit in response to a signal applied from the key selector when the storage of the sequentially divided channel frequencies is completed. How to save. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
