Description

철도차량용 문자방송 시스템Teletext broadcasting system

본 발명은 문자 표시기를 이용하여 열차내에서 탑승객에게 안내 및 광고를 실시하는 철도차량용 문자방송 시스템에 관한 것으로, 특히 차량 외부의 지령실에서 선정한 정보를 열차의 문자표시기로 실시간 전송하도록 된 철도차량용 문자방송 시스템에 관한 것이다. The present invention relates to a character broadcasting system for a railroad car that guides and advertises passengers in a train using a text display device. In particular, the text broadcasting system for a railroad car is configured to transmit information selected from a command room outside the vehicle to a text display of a train in real time. It's about the system.

일반적으로 철도차량은 열차의 내부 천장부에 문자 표시기가 구비되어, 정차역 정보와 날씨 및 그날의 주요 뉴스 등의 정보를 문자로 표시하여 승객에게 제공하고 있다. In general, a railway vehicle is provided with a text display on the inner ceiling of the train, and provides information to the passengers, such as station information, weather, and major news of the day.

여기서, 상기 문자 표시기를 이용한 정보 전달 과정은 문자표시기가 차량내에 탑재된 열차제어 정보 시스템(TIS)과 직렬 통신으로 연결되어, 이 TIS에 입력된 정보를 디스플레이 하도록 되어 있다. 한편, 상기 TIS에 입력된 정보는 차량의 출발전에 미리 입력되는 것인 바, 시간에 따라 갱신되는 정보를 입력하기는 거의 불가능하다.Here, the information transmission process using the character display is connected to the train control information system (TIS) mounted in the vehicle in serial communication, so that the information input to the TIS is displayed. On the other hand, since the information input to the TIS is previously input before the departure of the vehicle, it is almost impossible to input the information updated over time.

이에 따라, 통상의 문자 표시방송은 단순한 문자표시 기능만을 승객들에게 제공하게된다. 즉, 안내문이나 정차역 정보 또는 통상의 광고기능만을 수행하게 된다. Accordingly, the normal text display broadcast will provide passengers with only a simple text display function. That is, only the announcement or station information or a normal advertising function.

그러나, 정보에 대한 승객의 욕구가 점차적으로 증대되고 있고, 이러한 욕구를 충족시키기 위해 실시간으로 정보를 승객에게 전송하는 수단의 개발이 요구되고 있다. However, passengers' desire for information is gradually increasing, and development of means for transmitting information to passengers in real time is required to satisfy such desires.

따라서, 본 발명은 상기와 같은 승객의 요구를 충족시켜 철도차량의 서비스를 개선하기 위해 안출된 것으로, 원격지에 설지된 주장치를 통해 수집된 정보를 열차가 진행하는 지역에 설치된 기지국을 통해 열차로 전송하므로, 광고 및 안내방송 뿐 아니라 그 시각 발생된 각종 정보를 실시간으로 탑승객에 전달하도록 된 철도차량용 문자방송 시스템을 제공하는데 그 목적이 있다. Therefore, the present invention was devised to improve the service of the railway vehicle by satisfying the needs of the passengers as described above, and transmits the information collected through the assertion installed in the remote place through the base station installed in the area where the train proceeds. Therefore, it is an object of the present invention to provide a character broadcasting system for railway vehicles to deliver not only advertisements and announcements but also various information generated at the time to passengers in real time.

상기와 같은 목적을 달성하기 위하여 본 발명은 생활정보나 주요뉴스 및 기상정보를 입력하는 주장치(문자 편집장치)와 각 역사 또는 열차가 진행하는 주요지역에 설치되어 이 주장치로부터의 정보를 전송받는 기지국 및, 이 기지국으로부터의 정보를 수신하고 열차내부에 구비된 문자표시기를 통해 디스플레이시키는 문자표시부로 구성되어, In order to achieve the above object, the present invention provides a base station (text editing device) for inputting living information or main news and weather information, and a base station installed in a major area where each history or train proceeds to receive information from the main device. And a text display unit for receiving information from the base station and displaying the information through a text display provided in the train.

상기 주장치로 입력되는 정보가 광케이블을 통해 기지국으로 전송되고 무선으로 열차의 문자표시부로 전송되어 실시간으로 정보를 디스플레이하도록 된다. Information input to the main device is transmitted to the base station through the optical cable and wirelessly transmitted to the character display of the train to display the information in real time.

여기서, 상기 주장치와 기지국간의 문자정보 데이터 통신 인터페이스는 MKS모뎀과 광전송 장치(DTS)를 이용하여 구현된다.Here, the text information data communication interface between the main device and the base station is implemented using an MKS modem and an optical transmission device (DTS).

한편, 상기 기지국과 열차의 문자표시부와의 문자정보 데이터 통신 인터페이스는 전계통신 선로(LCX 케이블)를 이용하여 구현된다. On the other hand, the text information data communication interface between the base station and the character display unit of the train is implemented using an electric field communication line (LCX cable).

이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

즉, 작업자의 의지에 따라 정보가 선택되고, 실시간으로 전송될 수 있다.That is, information may be selected and transmitted in real time according to the worker's will.

여기서, 상기 주장치(1)와 기지국(2)간의 정보 테이터 인터페이스는 광전송 장치(4;DTS)를 통해 이루어진다. Here, the information data interface between the main device 1 and the base station 2 is made through the optical transmission device 4 (DTS).

한편, 상기 기지국(2)은 열차와의 정보통신 인터페이스를 원활히 하기 위하여, 열차가 진행하는 주요지점이나 각 역사에 설치되는 바, 증폭기와 레벨 제한 회로 고주파 변조 회로 및 LCX케이블(5;전계 통신선로)로 구성되어, 상기 주장치로부터 전송된 데이터를 증폭하고 레벨 제한하며 고주파 변조를 하여 증폭한 후 10W의 고주파 출력을 LCX케이블로 전송한다.On the other hand, the base station (2) is installed in the main point or each station where the train proceeds to facilitate the information communication interface with the train, the amplifier and level limit circuit high frequency modulation circuit and LCX cable (5; electric field communication line Amplify, level limit, and amplify the data transmitted from the main device, and transmit a high frequency output of 10W to the LCX cable.

여기서, 상기 기지국으로부터 열차로의 데이터 전송은 GWSK방식 전송으로써 그 전송속도는 최대 8000bps이다. In this case, the data transmission from the base station to the train is a GWSK transmission, the transmission speed is up to 8000bps.

또한, 상기 문자표시부(3)는 상기 기지국(2)의 LCX 케이블로부터 전송되는 신호를 수신하는 수신기와, 이 수신장치의 신호를 처리하는 CPU 및, 문자가 디스플레이되는 문자표시기(3')를 구비하여 구성되는 바, 기지국으로부터 전송된 VHF대의 전파가 상기 수신기에 의해 변환되어 CPU로 전송되고, 다시 문자표시기(3')로 전달된다. Further, the character display section 3 includes a receiver for receiving a signal transmitted from the LCX cable of the base station 2, a CPU for processing the signal of the receiver, and a character display 3 'for displaying characters. The radio wave of the VHF band transmitted from the base station is converted by the receiver, transmitted to the CPU, and then transmitted to the character display 3 '.

이때의 전송방식은 RS-482방식이며 그 전송속도는 1200bps 내지 9600bps로 된다. At this time, the transmission method is RS-482 and its transmission speed is 1200bps to 9600bps.

이상에서 설명한 바와 같이 본 발명에 의하면, 종래 지정된 정보의 표시만이 가능했던 표시장치와는 달리 주장치와 기지국으로부터의 무선을 통해 정보를 편집 및 전송하기 때문에 열차내 문자표시기에 필요한 정보를 실시간으로 제공하는 것이 가능하다. As described above, according to the present invention, unlike the display device which can display only designated information in the related art, since information is edited and transmitted over the air from the main device and the base station, information necessary for the in-train character display is provided in real time. It is possible to do
