Abstract

Discloses is a car audio anti-theft device for automobiles. The audio detached from the car, while the device is on, does not operate because the device links the audio with other systems of the car. If audio switch(15) is on, microprocessor(14) asks the key set(20) to issue a code, and code generator(21) generates a code of its own. The produced parallel code that is transmitted seriality by multiplexor(22) is again converted to a parallel code and supplied to the relational comparator(12). The result of comparing the code supplied to the relational comparator and the characteristic code stored in the ROM(13) is fed into microprocessor(14), which decides whether to operate the audio according the authorized code from the relational comparator. If the code generated from the key set and the one stored in the audio are different, the audio does not operate.

본 발명은 자동차의 오디오에 있어서 사용자의 어떠한 조작이 필요없이 항시 동작하는 오디오 도난방지 장치에 관한 것이다.The present invention relates to an audio anti-theft device that always operates in the audio of a car without any user's manipulation.

종래 오디오의 도난방지 장치는 사용자가 비밀코드를 입력하거나, 하차시 전면 키조작부를 탈착시켜야 하는등의 번거로움이 많았고, 비밀 코드를 잊어버리거나 전면 키 조작부를 잃어버리는 경우에는 큰 불편을 겪어야 한다.Conventional audio anti-theft device has a lot of trouble, such as the user to enter the secret code, or to remove the front key control unit when getting off, and if you forget the secret code or lose the front key control panel must suffer a great inconvenience.

또한 비밀 코드 방식의 경우에는 사용자의 입력에 대한 번거로움 때문에 비밀코드의 조합을 간단하게 하여, 오디오 도난후 코드가 해독되어 재사용하는 경우가 빈번하였다.In addition, in the case of the secret code method, a combination of secret codes is simplified due to the inconvenience of user input, and the code is frequently decoded and reused after theft of audio.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 오디오 도난방지 장치가 항시 작동을 하도록 하고, 다른 장치와 연계시키므로서 오디오만을 떼어내서는 작동을 시킬 수 없도록 하기 위한 오디오 도난방지 장치를 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, the audio anti-theft device to always operate, the audio anti-theft device to prevent the operation by removing the audio only by linking with other devices To provide.

이하 본 발명의 기술적 구성을 제1도를 참조하여 상세히 설명하면, 코드를 발생하는 코드발생기(21)와 멀티플랙서(22)로 이루어진 키셋트부(20)부, 디멀티플랙서(11)와 오디오의 고유코드번호를 저장하는 롬(13)과 상기 키셋부(20)에서 전송된 신호와 상기 롬(13)의 코드를 비교하는 비교연산기(12)와 상기 비교연산기의 출력에 따라 오디오의 동작을 결정하는 마이콤(14)으로 이루어진 오디오부(10)로 구성함을 그 기술적 구성상의 특징으로 한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, the technical configuration of the present invention will be described in detail with reference to FIG. 1. The keyset unit 20 and the demultiplexer 11 including a code generator 21 and a multiplexer 22 for generating a code will be described. And a comparator 12 for storing a unique code number of the audio and a signal transmitted from the keyset unit 20 and a code of the comparator 12 and the output of the comparator. It is characterized by the technical configuration of the audio unit 10 composed of the microcomputer 14 for determining the operation.

이러한 본 발명 오디오 도난 방지 장치는 제1도와 제2도에 나타낸 바와같이, 사용자가 오디오 스위치(15)를 온하면, 마이콤(14)에서는 키셋트부(20)로 코드를 발생할 것을 요구하게되고, 코드발생기(21)는 고유 코드를 발생하고 발생된 패럴(PARALLEL)코드는 멀티플랙서(22)를 통해 시리얼(SERI-AL)로 전송되어 오디오부(10)의 디멀티플랙서(11)는 다시 패럴코드로 변환하여 비교연산기(12)로 인가하게 된다.As shown in FIG. 1 and FIG. 2, when the user turns on the audio switch 15, the audio anti-theft device of the present invention requires the microcomputer 14 to generate a code to the key set unit 20. The code generator 21 generates a unique code, and the generated parallel code is transmitted to the serial SERI-AL through the multiplexer 22, so that the demultiplexer 11 of the audio unit 10 The code is converted to a parallel code and applied to the comparison operator 12.

비교연산기(12)로 인간된 코드와 롬(13)에 저장된 고유 코드번호를 비교하여 그 결과를 마이콤(14)으로 인가하면, 마이콤(14)에서는 상기 비교연산기(12)에서 인가된 신호에 따라 오디오의 동작을 결정하게 된다.When the code humanized by the comparison operator 12 and the unique code number stored in the ROM 13 are compared and the result is applied to the microcomputer 14, the microcomputer 14 according to the signal applied by the comparison operator 12. Determine the behavior of the audio.

그러므로, 도난된 오디오를 장착하였을 때에는 키셋부(20)에서 발생된 코드와 오디오부(10)에 저장된 코드가 다르므로 오디오는 동작을 하지 않게 된다.Therefore, when the stolen audio is mounted, the code generated by the keyset unit 20 and the code stored in the audio unit 10 are different, so that the audio does not operate.

이상에서 살펴 본 바와 같이, 본 발명인 오디오 도난방지 장치는 운전자가 도난방지를 위한 어떠한 동작을 취하지 않게 되며, 또한 오디오는 정해진 키셋트(20)에 의해서만 동작이 가능하므로 오디오의 도난을 사전에 방지를 할 수 있다. 그리고 숫자조합을 N자리수 만큼 늘릴 수 있으므로 코드해독이 그만큼 어려워 진다.As described above, the inventors of the present invention, the anti-theft device does not take any action for the driver to prevent theft, and also prevents theft of the audio in advance because the audio can be operated only by a predetermined key set 20. can do. And you can increase the number of combinations by N digits, which makes it harder to decode.
