Abstract

PURPOSE: A car network system is provided to use TCP/IP in a driver information system which controls and inputs/outputs car and driver information such as car driving information, management, and multimedia. CONSTITUTION: When a user pushes a button of a CD player(27) in order to listen a CD, it requests a DIS monitor(21) to be displayed through a DVD player(26) and an AM/FM tuner(25). The DIS monitor(21) sends a message to the CD player(27) through the AM/FM tuner(25) and the DVD player(26). When the message is not data which is related to the AM/FM tuner(25) and the DVD player(26), the AM/FM tuner(25) and the DVD player(26) passes the message. The CD player(27) operates to send sound data to the DIS monitor(21) so that the sound data is displayed on the DIS monitor(21). The DIS monitor(21) transmits a request message to the CD player(27).

More specifically, the present invention relates to a vehicle network system using TCP / IP. A vehicle network system.

종래의 차량용 네트워크 시스템에서는 TCP/IP를 적용한 사례가 없었다.In the conventional vehicular network system, TCP / IP has not been applied.

근래에는 MOST( MOST MEDIA ORIENTED SYSTEM TRANSPORT) 네크워크 시스템과 캔( CONTROLLER AREA NETWORK) 이 알려져 있다.In recent years, MOST (MOST MEDIA ORIENTED SYSTEM TRANSPORT) network systems and CONTROLLER AREA NETWORK are known.

CAN시스템은 1997년 이후에 자동차에 본격적으로 내장되었으며 오늘날 자동차의 제어용 네트워크로는 표준화가 되었다. 이곳에는 운전자의 안전과 편의 기능을 위한 다량의 제어정보가 전달되고 있다.CAN systems have been built into automobiles since 1997 and have become standardized in today's automotive control networks. A large amount of control information is transmitted here for the driver's safety and convenience functions.

MOST 네트워크는 최근에 개발되고 있는 시스템으로써 멀티미디어용 네트워크이다. 물론 그 속에서 제어용 데이터를 전송할 수 있는 기능도 있지만 일반적으로 라디오, 스피커, LCD 모니터를 가지며 HMI(human-machine interface)를 담당하는 메인유니트 등으로 구성되어지며, CAN에 대해서는 비교할 수 없을 정도로 고속의 영상, 음성 데이타를 전송하고 있다.The MOST network is a recently developed system for multimedia. Of course, there is a function to transmit control data in it, but it is generally composed of a main unit having a radio, a speaker, an LCD monitor, and a human-machine interface (HMI). Video and audio data are transmitted.

그러나 이러한 MOST네트워크 시스템은 고가형이라는 문제점이 있다.However, such a MOST network system has a problem of being expensive.

본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로서, 본 발명의 목적은 보편화되어 있고 저렴한 TCP/IP를 이용한 차량용 네트워크 시스템을 제공하는데 있다.SUMMARY OF THE INVENTION The present invention has been made to overcome the above-mentioned conventional problems, and an object of the present invention is to provide a vehicle network system using a universal and inexpensive TCP / IP.

이하, 본 발명의 실시예를 첨부한 도면을 참조하여 설명하기로 한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

도 1을 참조하면, 본 발명에 따른 TCP/IP를 이용한 차량용 네트워크 시스템이 도시되어 있다.1, there is shown a vehicular network system using TCP / IP in accordance with the present invention.

차량 멀티미디어 시스템에서 주요 기능인 멀티미디어의 네트워크를 TCP/IP로 구현하는 것이 본 발명의 목적이다. 일반적으로 차량내 멀티미디어 제어는 단순한 1:1 와이어링으로 연결되어 있다.It is an object of the present invention to implement a network of multimedia, which is a major function in a vehicle multimedia system, using TCP / IP. In-vehicle multimedia control is typically connected by simple 1: 1 wiring.

현재 TCP/IP는 퍼스날 컴퓨터에 적용되어 있다. 요즘에는 차량의 모바일 오피스개념이 일반화되고 있는데, 이러한 차량의 여러가지 멀티미디어 제품을 TCP/IP로 억세스하고자 한다.TCP / IP is now applied to personal computers. Nowadays, the concept of the mobile office of a vehicle is becoming common, and various multimedia products of the vehicle are to be accessed by TCP / IP.

도 1을 참조하면, 각종 멀티미디어 구성요소, 즉 DIS 모니터(21), 네비게이션 모듈(22), HMI 모니터(23), 게이트웨이(24), AM/FM 튜너(25), DVD 플레이어(26), CD플레이어(27), DSP(28), 기타 제품들이 순차적으로 연결되고 각 연결부가 TCP/IP(10) 네트워크로서 이루어진다.Referring to Figure 1, various multimedia components, i.e. DIS monitor 21, navigation module 22, HMI monitor 23, gateway 24, AM / FM tuner 25, DVD player 26, CD The player 27, DSP 28, and other products are connected in sequence and each connection is made as a TCP / IP 10 network.

상기와 같은 구성에 의해서 본 발명에 따른 TCP/IP를 이용한 차량용 네트워크 시스템은 도 2와 같이 작동된다.By the above configuration, the vehicle network system using TCP / IP according to the present invention operates as shown in FIG.

사용자가 CD를 듣고자 가정한다.Suppose a user wants to listen to a CD.

사용자가 CD플레이어(27) 버튼을 누르면 DVD플레이어(26), AM/FM 튜너(25)를 거쳐서 DIS모니터(21)에 화면 표시를 요구하게 된다.When the user presses the button of the CD player 27, the display is requested by the DIS monitor 21 via the DVD player 26 and the AM / FM tuner 25.

DIS 모니터(21)에서 다시 역순으로 즉 AM/FM 튜너(25), DVD플레이어(26)를 거쳐 CD플레이어(27)에 요구를 받아들이겠다는 메시지를 보낸다.The DIS monitor 21 again sends a message to the CD player 27 in reverse order, ie, via the AM / FM tuner 25 and the DVD player 26.

여기서 AM/FM 튜너(25), DVD플레이어(26)는 자기에 관련된 메시지가 아니면 단순히 메시지를 패싱만 한다.Here, the AM / FM tuner 25 and the DVD player 26 simply pass messages unless they are messages related to them.

그러면, CD플에이어(26)가 작동되고, 그 음악 데이터는 같은 경로로 DIS 모니터(21)로 보내져서 디스플레이된다.Then, the CD player 26 is activated, and the music data is sent to the DIS monitor 21 and displayed by the same path.

또한, DIS 모니터(21)는 CD플레이어(27)에 요구 메시지를 전송한다.The DIS monitor 21 also transmits a request message to the CD player 27.

상술한 바와같이, 본 발명에 따른 TCP/IP를 이용한 차량용 네트워크 시스템의 링 토폴로지의 장점은 모든 유니트를 와이어로 연결하는 것보다 와이어의 양이 줄어들고(이때 충분한 전송 속도가 요구된다), 멀티 스레드 개념을 이용하면 각 멀티미디어의 제어가 좀 더 쉽게 된다. 예로서, 모니터가 프론트와 리어 두 대가 있다면 각 모니터에 다른 화면을 나오게 할 수 있다. 프론트에는 네비게이션, 리어에는 TV 이런 식으로 표시가 가능하다. 두명의 유저가 네트워크를 이용하여 멀티 게임도 가능하게 된다.As described above, the advantage of the ring topology of the vehicular network system using TCP / IP according to the present invention is that the amount of wire is reduced (when sufficient transmission speed is required), rather than connecting all the units by wire, the multi-thread concept Using it makes it easier to control each multimedia. For example, if your monitor has two front and one rear, you can have a different screen on each monitor. Navigation can be displayed on the front and TV on the rear. Two users can play a multi game using the network.

그리고 TCP/IP 프로토콜은 매우 일반적인 프로토콜이여서 가격 경쟁면에서 상당히 우월하게 된다.And the TCP / IP protocol is a very common protocol, which makes it quite superior in price competition.

이상에서 설명한 것은 본 발명에 따른 TCP/IP를 이용한 차량용 네트워크 시스템을 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구범위에서 청구하는 바와같이 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자가라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.What has been described above is just one embodiment for implementing a vehicular network system using TCP / IP according to the present invention, and the present invention is not limited to the above embodiment, as claimed in the following claims. Without departing from the gist of the present invention, anyone of ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.
