Abstract

본 발명은 리모콘에 비밀번호를 입력시켜 다수의 VCR셋 존재시 각각의 셋을 선별하여 조정하거나 개인의 보안 목적으로사용할 수 있도록 한 리모콘의 비밀번호 제어방법에 관한 것으로, 사용자가 누르는 버튼에 따른 신호를 입력시키기 위한키매트릭스(10)와, 상기 키매트릭스(10)에 의해 신호가 입력될 때 발진하는 크리스탈 발진기(20)와, 상기 크리스탈 발진기(20)에 의해 동작되며, 상기 키매트릭스(10)의 버튼이 눌러지는 경우에 따라 해당모드로 동작시키도록 제어하는 마이컴(30)과, 상기 마이컴(30)의 제어에 따라 적외선 펄스를 출력시키는 적외선 센서(40)로 구성되는 리모콘에 있어서, 비밀번호 유무를 판단하여 비밀번호가 없는 경우에는 비밀번호를 입력시킬것인가를 판단하고, 비밀번호가 있는 경우에는 3개 코드 체계를 수행하는 제1단계와, 상기 제1단계에서 비밀번호를 입력시킬 경우 비밀번호를 저장하고, 비밀번호를 입력시키지 않을 경우 2개 코드체계를 수행하고 종료하는 제2단계와, 상기 제1단계에서 3개 코드체계 수행 후 비밀번호를 비교하여 비밀번호가 다르면 에러를 출력시키고 종료하며, 비밀번호가 같으면 2개코드 체계를 수행한 후 종료하는 제3단계로 이루어진다.The present invention relates to a password control method of a remote control to input a password to the remote control to select and adjust each set in the presence of a plurality of VCR sets or to use for personal security purposes, and inputs a signal according to a button pressed by the user A key matrix 10, a crystal oscillator 20 oscillating when a signal is input by the key matrix 10, and a button of the key matrix 10 operated by the crystal oscillator 20. In the remote control comprising a microcomputer 30 for controlling to operate in the corresponding mode in response to the pressing, and an infrared sensor 40 for outputting an infrared pulse under the control of the microcomputer 30, the presence or absence of a password is determined. If there is no password, it is determined whether to enter a password, and if there is a password, the first step of performing three code systems; If the password is entered in step 1, the password is stored, and if the password is not entered, the second step of performing and ending the two code systems and the password after performing the three code systems in the first step are compared to the password. If it is different, an error is output and terminated. If the password is the same, the third step is performed after performing two code systems.

Claims (3)

사용자가 누르는 버튼에 따른 신호를 입력시키기 위한 키매트릭스(10)와, 상기 키매트릭스(10)에 의해 신호가 입력될 때 발진하는 크리스탈 발진기(20)와, 상기 크리스탈 발진기(20)에 의해 동작되며, 상기 키매트릭스(10)의 버튼이 눌러지는 경우에 따라 해당 모드로 동작시키도록 제어하는 마이컴(30)과, 상기 마이컴(30)의 제어에 따라 적외선 펄스를 출력시키는 적외선 센서(40)로 구성되는 리모콘에 있어서, 상기 적외선 센서로부터 신호가 입력될 때 비밀번호 유무를 판단하여 비밀번호가 없는 경우에는 비밀번호를 입력시킬것인가를 판단하고, 비밀번호가 있는 경우에는 3개 코드 체계를 수행하는 제1단계와, 상기 제1단계에서 비밀번호를 입력시킬 경우 비밀번호를 저장하고, 비밀번호를 입력시키지 않을경우 2개 코드체계를 수행하고 종료하는 제2단계와, 상기 제1단계에서 3개 코드체계 수행 후 비밀번호를 비교하여 비밀번호가 다르면 에러를 출력시키고 종료하며, 비밀번호가 같으면 2개코드 체계를 수행한 후 종료하는 제3단계로 이루어짐을특징으로 하는 리모콘의 비밀번호 제어방법.It is operated by a key matrix 10 for inputting a signal according to a button pressed by a user, a crystal oscillator 20 oscillating when a signal is input by the key matrix 10, and the crystal oscillator 20. And a microcomputer 30 for controlling to operate in a corresponding mode when the button of the key matrix 10 is pressed, and an infrared sensor 40 for outputting an infrared pulse under the control of the microcomputer 30. In the remote control, when the signal is input from the infrared sensor to determine whether there is a password to determine whether to enter a password, if there is no password, and if there is a first step of performing three code schemes, A second step of storing the password when the password is input in the first step and performing and ending two code systems if the password is not input; In the first step, after performing the three code systems, the password is compared and the password is different, and if the password is different, the error is output and terminated. If the password is the same, the second step is performed after performing the two code systems. Password control method. 제1항에 있어서, 상기 3개 코드 체계가 제1부분은 비밀번호, 제2부분은 회사코드, 제3부분은 기능코드로이루어짐을 특징으로 하는 리모콘의 비밀번호 제어방법.The method of claim 1, wherein the three code systems comprise a first part of a password, a second part of a company code, and a third part of a function code. 제1항에 있어서, 상기 제2단계에서 비밀번호 입력 후 리모콘 사용할시 3개 코드 체계로 전환됨을 특징으로하는 리모콘의 비밀번호 제어방법.The password control method of claim 1, wherein the password is switched to three code systems when the remote controller is used after the password is input in the second step. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
