본 발명은 엠오에스티(MOST) 적용차량의 작동 인증장치에 관한 것으로서, 더욱 상세하게는 MOST링 구조 사이에 링이 연결되지 않는 부분을, 광케이블 사이의 터널이 되게 하는 자동차키의 관통홀로 연결하여 하드웨어적인 인증절차를 수행하는 작동 인증장치에 관한 것이다.The present invention relates to an operation authentication device for an MOST applied vehicle, and more particularly, by connecting a portion in which a ring is not connected between MOST ring structures to a through-hole of a car key, which becomes a tunnel between optical cables. The present invention relates to an operation authentication device for performing an authentication process.

최근 자동차에는 라디오, 테이프, CD, CD 체인저, DVD, 네비게이션 뿐만 아니라 LCD 모니터가 차량 내의 전후 또는 뒷자리마다 장착되고 있고 최근에는 텔레매틱스 분야로써 인터넷 접속, 교통정보처리, 사고 전달 등 많은 멀티미디어 기기들이 장착되고 있으며, 이 멀티미디어 기기들의 연결을 위해 차량에 광통신 멀티미디어 네트워크인 MOST(Media Oriented System Transport: MOST) 시스템을 적용하고 있다. In recent years, automobiles are equipped with radios, tapes, CDs, CD changers, DVDs, navigations as well as LCD monitors in the front and rear of the vehicle. Recently, many multimedia devices such as internet access, traffic information processing and accident transmission are installed as telematics fields. In order to connect the multimedia devices, MOST (Media Oriented System Transport) system is applied to the vehicle.

상기 차량에 장착되는 멀티미디어 기기들은 링(RING) 형태로 구성되는 MOST 링 상에서 구현되고, 상기 MOST 링 상에 구현되고 있는 각종 멀티미디어 기기들은 MOST 시스템 내에서 어디에서든지 동작 제어가 가능하며, 또한 이용이 가능하게 된다.The multimedia devices mounted on the vehicle are implemented on a MOST ring configured in a ring form, and various multimedia devices implemented on the MOST ring can be controlled and operated anywhere in the MOST system. Done.

즉 MOST는 플라스틱 광섬유(Plastic Optical Fiber)를 사용한 자동차용 저가, 고대역폭 데이터 통신의 국제 표준으로서, 링 구조의 광섬유 네트워크상에 멀티미디어 기기들을 연결한다.MOST is an international standard for low-cost, high-bandwidth data communications for automobiles using plastic optical fibers that connect multimedia devices over ring-shaped fiber optic networks.

도 1은 종래 MOST가 적용된 차량의 배선도로서, 차량이 ACC 온되면 마스터 유닛(보통 헤드 유닛)(20a)이 이를 감지하여 광케이블(50)을 통해 링에 연결된 순서대로 멀티미디어 기기(10)들을 작동시킨다.1 is a wiring diagram of a vehicle to which a conventional MOST is applied. When the vehicle is ACC-on, the master unit (usually the head unit) 20a detects this and operates the multimedia devices 10 in the order connected to the ring through the optical cable 50. .

반대로 차량의 오프되면 마스터 유닛(20a)이 이를 감지하여 링에 연결된 멀 티미디어 기기(10)들이 종료(Shutdown)할 수 있는지 확인 후 시스템 전체를 종료한다.On the contrary, when the vehicle is turned off, the master unit 20a detects this, checks whether the multimedia devices 10 connected to the ring can shut down, and then shuts down the entire system.

이를 좀 더 상세히 설명하면, MOST 네트워크는 몇 개의 멀티미디어 기기(10a,10b,10c,10d)들이 링 구조로 연결된다.In more detail, in the MOST network, several multimedia devices 10a, 10b, 10c, and 10d are connected in a ring structure.

이와 같은 MOST 네트워크의 작동을 위해서 먼저 마스터 유닛(보통 헤드 유닛)(20a)이 ACC 신호를 받아 웨이크업(Wake-Up)을 하게 되면, 광신호를 생성하여 MOST 링으로 광신호를 내보내게 된다.For the operation of the MOST network, when the master unit (usually the head unit) 20a receives the ACC signal and wakes up, the optical unit generates an optical signal and sends the optical signal to the MOST ring.

다른 슬레이브 멀티미디어 기기(10a,10b,10c,10d)는 차량의 신호가 아니라 마스터 유닛(20a)이 생성한 광신호를 받아 웨이크업 하게 되고 웨이크업하게 된 멀티미디어 기기는 광신호를 내보내어 다음 멀티미디어 기기가 웨이크업할 수 있게 한다.The other slave multimedia devices 10a, 10b, 10c, and 10d receive the optical signal generated by the master unit 20a, not the signal of the vehicle, and wake up. The multimedia device that wakes up sends the optical signal to the next multimedia device. To wake up.

마스터 유닛(20a)으로부터 웨이크업을 시작하여 마지막에 연결된 멀티미디어 기기가 웨이크업하여 광신호를 내보내면, 마스터 유닛(20a)이 링 네트워크가 완성되었음을 인식하고, 위치 체크, 각 멀티미디어 기기의 기능 확인 등과 같은 네트워크 정리작업을 하게 된다.When wake-up starts from the master unit 20a and the last connected multimedia device wakes up and emits an optical signal, the master unit 20a recognizes that the ring network is completed, checks the position, checks the function of each multimedia device, and the like. The same network cleanup is done.

이와 같이 각 멀티미디어 기기(10)들이 광으로 마스터 유닛(20a)으로부터 광신호를 받는 것이 아니라, 전기적으로 마스터 유닛(20)에서 신호를 받은 경우도 있으나, MOST의 장점인 배선수 감소를 위해서 잘 쓰이지 않는다.As such, the multimedia devices 10 may not receive an optical signal from the master unit 20a through optical light, but may receive an electric signal from the master unit 20 electrically. Do not.

이와 같이 MOST 네트워크는 하나의 광케이블(50)을 통해서 컨트롤메시지, 영상신호, 음성신호를 보낼 수 있는 네트워크로, 기본적으로 멀티미디어 기기(AMP, DVDC, 튜너 등)에 사용된다.As such, the MOST network is a network that can transmit control messages, video signals, and audio signals through one optical cable 50, and is basically used for multimedia devices (AMP, DVDC, tuner, etc.).

차체(Body) 네트워크나 파워트레인 및 새시 네트워크 등은 CAN 또는 LIN을 이용하고 있으며, MOST를 사용하지 않는다.Body networks, powertrain and chassis networks use CAN or LIN and do not use MOST.

즉, MOST 네트워크는 멀티미디어 기기(10)에 사용되는 네트워크로써 자동차키가 삽입 상태가 아니면 MOST가 온 될 경우는 없다.That is, the MOST network is a network used for the multimedia apparatus 10, and the MOST is not turned on unless the car key is inserted.

그러나 종래의 MOST 네트워크는 광을 이용한 웨이크업시, 시동키가 ACC 포지션에 위치되면 아무런 인증절차 없이 네트워크가 활성화되는 문제점이 있었다.However, the conventional MOST network has a problem that the network is activated without any authentication procedure when the ignition key is located at the ACC position when the user wakes up using the light.

본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로서, MOST링 구조 사이에 링이 연결되지 않는 부분을 두고 이 부분을 광케이블 사이의 터널이 되게 하는 자동차키의 관통홀로 연결하여 하드웨어적인 인증절차를 수행할 수 있도록 하는 MOST 적용차량의 작동 인증장치를 제공하는데 그 목적이 있는 것이다.The present invention has been made to solve the above-mentioned problems, and the hardware does not perform the authentication procedure by connecting the through-hole of the car key to make the tunnel between the optical cable and the part that the ring is not connected between the MOST ring structure The aim is to provide a device for authenticating MOST vehicles.

상술한 목적을 달성하기 위한 본 발명의 실시예에 따른 MOST 적용차량의 작동 인증장치는, 다수의 멀티미디어 기기들이 광케이블을 통해 링 구조로 연결되는 MOST를 적용한 차량에 전원을 공급하여 멀티미디어 기기들을 작동하는 장치에 있어서,The operation authentication apparatus of the MOST applied vehicle according to the embodiment of the present invention for achieving the above object, by supplying power to the vehicle to which the MOST to which a plurality of multimedia devices are connected in a ring structure via an optical cable to operate the multimedia devices In the apparatus,

상기 광케이블에는 링의 경로를 차단함으로써 링이 연결되지 않는 부분을 구비하고, 자동차키에는 송신홈과 수신홈을 갖는 관통홀을 형성하되, 상기 링이 연결되지 않는 부분에 자동차키가 삽입되어 자동차키의 관통홀이 끊어진 광케이블 간의 전송 통로를 연결하여 멀티미디어 기기가 작동되어 MOST 네트워크를 형성하는 것을 특징으로 한다.The optical cable has a portion where the ring is not connected by blocking the path of the ring, and a through-hole having a transmitting groove and a receiving groove is formed in the car key, and the car key is inserted into the portion where the ring is not connected. It is characterized by forming a MOST network by operating a multimedia device by connecting the transmission path between the optical cables through which the through-holes are broken.

이하 본 발명의 실시예에 대하여 첨부된 도면을 참고로 그 구성 및 작용을 설명하기로 한다.Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

도 2a와 도 2b는 본 발명에 따른 자동차키의 관통홀을 이용한 작동 인증장치를 나타내는 개념도이다.2A and 2B are conceptual views illustrating an operation authentication device using a through hole of a car key according to the present invention.

도 2a에서와 같이, 다수의 멀티미디어 기기(10)들이 광케이블(50)을 통해 링 구조로 연결되는 MOST 네트워크에서 광케이블(50)의 도중이 끊어지는 링이 연결되지 않는 부분을 두어(상기 광케이블(50)에는 링의 경로를 차단함으로써 링이 연결되지 않는 부분을 구비하고), 광신호의 전송이 중도에서 차단되도록 하여 네트워크가 형성되지 않도록 한다.As shown in FIG. 2A, in a MOST network in which a plurality of multimedia devices 10 are connected in a ring structure through an optical cable 50, a portion in which an intermediate ring of the optical cable 50 is cut off is not connected (the optical cable 50 ) Is provided with a portion where the ring is not connected by blocking the path of the ring), and the transmission of the optical signal is blocked midway so that a network is not formed.

도면에서는 제1멀티미디어 기기(10a)와 제2멀티미디어 기기(10b) 사이의 광케이블(50)이 링이 연결되지 않는 부분이 되고, 이에 의해 제1멀티미디어 기기(10a)의 광신호가 제2멀티미디어 기기(10b)에 전달되지 않아 네트워크가 완성되지 않게 된다.In the drawing, the optical cable 50 between the first multimedia device 10a and the second multimedia device 10b becomes a portion where the ring is not connected, whereby the optical signal of the first multimedia device 10a is transmitted to the second multimedia device ( 10b), the network will not be completed.

즉, 도 2a에서는 MOST 링이 완성되지 않아 시스템이 작동 하지 못하게 된다.That is, in FIG. 2A, the MOST ring is not completed and the system does not work.

도 2b와 같이 링의 연결이 차단된 부분에 관통홀(36)이 형성된 자동차키(30)를 삽입하여, 이 관통홀(36)이 광신호가 통과하는 터널이 되게 함으로써 네트워크가 형성된다.As shown in FIG. 2B, a network is formed by inserting the car key 30 having the through hole 36 formed at a portion where the ring connection is blocked, and making the through hole 36 a tunnel through which an optical signal passes.

도면에서는 제1멀티미디어 기기(10a)와 제2멀티미디어 기기(10b)를 연결하는 광케이블(50)에 자동차키(30)가 삽입되면, 이 자동차키(30)의 관통홀(36)이 광케이블(50) 간의 전송 통로가 연결이 되어 MOST 링이 형성되고 시스템을 작동하게 된다.In the drawing, when the car key 30 is inserted into the optical cable 50 connecting the first multimedia device 10a and the second multimedia device 10b, the through hole 36 of the car key 30 is connected to the optical cable 50. The transmission path between the wires is connected, forming a MOST ring and operating the system.

도 3a와 도 3b는 도 2b에 나타낸 키의 구조도 및 단면도이다.3A and 3B are structural diagrams and cross-sectional views of the key shown in FIG. 2B.

도시된 바와 같이, 자동차키(30)는 본체(32)와 손잡이(34)로 이루어지며 본체(32)에는 송신홈(36a)과 수신홈(36b)을 갖는 관통홀(36)이 형성된다.As shown, the car key 30 is composed of a main body 32 and the handle 34, the through-hole 36 having a transmission groove 36a and the receiving groove 36b is formed in the main body 32.

상기 자동차키(30)의 송신홈(36a)과 수신홈(36b)은 제1멀티미디어 기기(10a)의 송신 광케이블(50a)과 제2멀티미디어 기기(10b)의 수신 광케이블(50b)에 연결되며, 이때 정확한 송신홈(36a)과 수신홈(36b)을 가진 자동차키(30)의 삽입이 이루어져야, 송신 광케이블(50a)과 수신 광케이블(50b)이 연결되어 관통홀(36)이 광케이블(50a,50b) 간의 전송 통로를 연결하여 제1멀티미디어 기기(10a)와 제2멀티미디어 기기(10b)가 통신할 수 있게 된다.The transmission groove 36a and the reception groove 36b of the car key 30 are connected to the transmission optical cable 50a of the first multimedia device 10a and the reception optical cable 50b of the second multimedia device 10b. At this time, the car key 30 having the correct transmission groove 36a and the reception groove 36b should be inserted, so that the transmission optical cable 50a and the reception optical cable 50b are connected to each other so that the through holes 36 are optical cables 50a and 50b. The first multimedia device 10a and the second multimedia device 10b can communicate with each other by connecting a transmission path between the first and second multimedia devices 10a and 10b.

상기 자동차키(30)의 구조는 차량별 인증 절차를 위해서 제1멀티미디어 기기(10a)의 송신 광케이블(50a)과, 제2멀티미디어 기기(10b)의 수신 광케이블(50b)이 연결되는 위치, 즉 송신홈(36a)과 수신홈(36b)을 각 차별로 다른 위치에 형성하여, 정확한 송신홈(36a)과 수신홈(36b)을 가진 자동차키(30)의 삽입이 이루어져야 제1멀티미디어 기기(10a)와 제2멀티미디어 기기(10b)의 통신할 수 있게 함이 바람직하다.The structure of the vehicle key 30 is a position where the transmission optical cable 50a of the first multimedia device 10a and the reception optical cable 50b of the second multimedia device 10b are connected, i.e., for a vehicle-specific authentication procedure. The groove 36a and the receiving groove 36b are formed at different positions by differentiation, so that the car key 30 having the correct transmitting groove 36a and the receiving groove 36b must be inserted into the first multimedia device 10a. It is desirable to enable communication of the second multimedia device 10b with the second multimedia device 10b.

도 4는 본 발명에 따른 작동 인증방법의 순서도이다.4 is a flowchart of an operation authentication method according to the present invention.

몇 개의 멀티미디어 기기들이 링 구조로 연결된 상태에서, 마스터 유닛(보통 헤드 유닛)이 ACC 신호를 받으면(S402), 웨이크업(Wake-Up)을 하게 되고, 광신호를 생성하여 MOST 링으로 광신호를 내보내게 된다(S404).When several multimedia devices are connected in a ring structure, when the master unit (usually the head unit) receives the ACC signal (S402), a wake-up is performed. Will be exported (S404).

제1멀티미디어 기기는 마스터 유닛이 생성한 광신호를 받아 웨이크업 하게 되고 광신호를 전송하게 되는 바(S406), 자동차키가 삽입되는 경우에(S408), 상기 관통홀이 끊어진 광케이블 간의 전송 통로를 연결하여 마지막 제n멀티미디어 기기에서도 광신호를 받아 웨이크업 하게 되고, 광신호를 마스터 유닛에 전송하게 된다(S410).The first multimedia device receives the optical signal generated by the master unit and wakes up and transmits the optical signal (S406). When the car key is inserted (S408), the first multimedia device opens a transmission path between the optical cables in which the through-hole is broken. By connecting, the last n-th multimedia device receives the optical signal and wakes up, and transmits the optical signal to the master unit (S410).

상기 마스터 유닛은 링 네트워크가 형성되었음을 인식하고(S412), 위치 체크, 각 멀티미디어 기기의 기능 확인 등과 같은 네트워크 정리작업을 하게 된다.The master unit recognizes that the ring network is formed (S412), and performs network cleanup such as location check and function check of each multimedia device.

상기 자동차키가 삽입되지 않는 경우에(S408), 광신호의 전송이 광케이블의 도중에 차단되어 마지막 제n멀티미디어 기기에 대한 웨이크업을 실패하게 된다(S422).If the car key is not inserted (S408), the transmission of the optical signal is interrupted in the middle of the optical cable, thereby failing to wake up the last n-th multimedia device (S422).

상기 마스터 유닛이 제n멀티미디어 기기에서 광신호가 전송되지 않는 경우에 네트워크가 형성되지 않았음을 인식한다(S424).When the master unit does not transmit an optical signal from the n-th multimedia device, the master unit recognizes that no network is formed (S424).

이상에서와 같이 종래 MOST 적용차량은 아무런 인증장치 없이 전원만 인가하면 작동하게 되나, 본 발명에 의하면 자동차키가 삽입이 되어야 시스템이 작동할 수 있게 되어 간단한 하드웨어적인 방식을 통해서 시스템의 인증절차를 할 수 있다.As described above, the conventional MOST applied vehicle operates only when power is applied without any authentication device, but according to the present invention, the system can be operated only when the car key is inserted to perform the system authentication process through a simple hardware method. Can be.

이상에서 살펴본 바와 같이 본 발명에 의하면, MOST링 구조 사이에 링이 연 결되지 않는 부분을 두고, 그 부분을 광케이블 사이의 터널이 되게 하는 자동차키의 관통홀로 연결하여 하드웨어적인 인증절차를 수행할 수 있도록 한다.As described above, according to the present invention, there is a part where the ring is not connected between the MOST ring structures, and a hardware authentication procedure can be performed by connecting the part to the through-hole of the car key that becomes a tunnel between the optical cables. Make sure
