Abstract
본 발명은 비밀코드를 입력하여야만 동작하는 자동차 오디오에 관한 것으로, 사용자가 외우기 쉽게 임의대로 비밀코드를 변경할 수 있도록 한 자동차 오디오의 비밀코드 변경장치 및 그 제어방법에 관한 것으로, 숫자 키의 조합으로 이루어진 코드입력부(20)와; 자동차의 고유번호에 따른 비밀코드를 저장한 롬(40); 상기 코드 입력부(20)에서 입력된 비밀코드와 롬(40)에 저장되어져 있는 비밀코드를 비교하는 비교기(30)와; 상기 코드입력부(50)에 입력되는 내용을 표시하는 표시부(50)와; 상기 비교기(30)의 결과에 따라 오디오(70)를 제어하는 마이콤(10)으로 이루어진 자동차 오디오에 있어서, "쓰기/읽기"가 가능한 롬(41)과; 사용자의 선택신호를 인가하는 비밀코드변경스위치(10)로 구성하여, 사용자의 선택신호를 비밀코드변경스위치(10)로부터 인가 받아 코드입력부(20)로 입력된 현재의 비밀코드가 정확한지를 판단하여 그 결과로서 새로운 비밀코드의 입력을 결정하는 비밀코드확인단계(S1)와; 코드입력부(20)로부터 입력된 새로운 비밀코드를 롬(41)에 저장하는 비밀코드입력단계(S2)로서 새로운 비밀코드를 입력 할 수 있도록 함으로서, 사용자가 비밀코드를 임의로 변경하는 것이 가능하여, 사용자가 외우기 쉬운 번호나 좋아하는 번호로 비밀코드를 정할 수 있음은 물론이며, 새로운 비밀코드로 수정할 때에 현재 사용중인 비밀코드를 입력하여야 하므로 타인에 의한 코드변경을 막을 수 있다.The present invention relates to a car audio which operates only when a secret code is input, and relates to a device for changing a secret code of a car audio and a method of controlling the same, wherein the secret code can be changed at random by a user easily. A code input unit 20; ROM 40 for storing a secret code according to the unique number of the vehicle; A comparator 30 for comparing the secret code inputted from the code input unit 20 with the secret code stored in the ROM 40; A display unit 50 which displays contents input to the code input unit 50; In the car audio comprising a microcomputer 10 for controlling the audio 70 according to the result of the comparator 30, ROM (41) capable of "write / read"; By configuring the secret code change switch 10 for applying the user's selection signal, by receiving the user's selection signal from the secret code change switch 10 to determine whether the current secret code input to the code input unit 20 is correct As a result, a secret code verification step (S1) for determining the input of a new secret code; By allowing a new secret code to be input as a secret code input step S2 for storing a new secret code input from the code input section 20 in the ROM 41, the user can change the secret code arbitrarily, so that the user Of course, you can set a secret code with a number that you can easily memorize or your favorite number, and when you modify it with a new secret code, you need to enter the current secret code so that you can prevent the code change by others.
