Typically, the subway is configured by connecting a plurality of electric cars (20a to 20m), the second transceiver 40a is installed on the side wall of the control vehicle, which is the first electric car with a driver's seat, and each electric vehicle is connected to a wired or wireless LAN (Local Connect to each other using Area Network.
지하철 역사내에 설치되는 상기 중계장치(10)는 인터넷망을 통해 동영상 정보를 취합, 편집하여 전동차(20a∼20m)로 전달하거나 별도로 설립된 인터넷 방송국의 방송신호를 전동차(20a∼20m)로 중계하도록 구성된다. 즉, 도 2에 도시된 것처럼 중계장치(10)는 모뎀과 같은 통신모듈(11)을 통해 외부의 정보제공자와 접속되며, 이 통신모듈(11)을 통해 제공되는 동영상 정보신호는 정보중계 컴퓨터(12)에 의해 편집되거나 전동차(20a∼20m)로 중계된다.The repeater 10 installed in the subway station collects and edits video information through the Internet network and transmits it to the electric vehicles 20a to 20m or to relay broadcast signals of a separately established internet broadcasting station to the electric vehicles 20a to 20m.

통상적으로 제1 송수신기(30a∼30m)는 중계장치(10)로 부터 수십미터 이상 이격된 지점에 설치되는데, 본 실시예에서는 원활한 데이터 전송을 위해 RS-422 인터페이스부(13,14)를 이용하여 중계장치(10)와 제1 송수신기(30a∼30m)를 서로 접속시켰다. 따라서, 1.2Km의 이격거리에서도 최대 10Mbps의 속도로 데이터를 전송할 수 있다.Typically, the first transceivers 30a to 30m are installed at points separated by several tens of meters or more from the relay device 10. In this embodiment, the RS-422 interface units 13 and 14 are used for smooth data transmission. The relay device 10 and the first transceivers 30a to 30m were connected to each other.

An electric wire or an optical fiber may be used as the signal line. In the case of using the electric line as the signal line, the shield line should be used and the shield should be grounded so as not to be affected by the arc and high voltage noise generated from the electric vehicles 20a to 20m.
한편, 본 실시예에서는 지하철 터널벽과 전동차(20a∼20m)에 각각 설치된 제1 및 제2 송수신기(30a∼30m)(40a)가 적외선 방식을 이용하여 서로 통신하지만,RF(Radio Frequency) 방식을 이용하여 서로 통신하도록 구성할 수도 있다. 이는 당해 기술분야에 통상의 지식을 지닌 자라면 용이하게 적용할 수 있다.Meanwhile, in the present embodiment, the first and second transceivers 30a to 30m and 40a respectively installed on the subway tunnel wall and the electric vehicles 20a to 20m communicate with each other by using an infrared method, but use a radio frequency (RF) method.

And a receiving module 31, which is paired with the transmitting module 32, receives and amplifies an infrared pulse signal output from the second transceiver 40a.
상기 타원빔 형성용 렌즈(32a)는 적외선 펄스신호를 집속시키고 수광패턴을 예리하게 형성시켜 광통신시 발생되는 공간손실을 줄여준다. 이로인해, 제1 송수신기(30a∼30m)의 설치간격이 넓어짐에 따라 제1 송수신기(30a∼30m)의 설치갯수를 절감시킬 수 있을 뿐만 아니라 터널벽 상단에 설치된 형광등의 불빛에 의한 적외선 방해파의 영향을 최소화시킬 수 있다. 아울러, 상기 렌즈(32a)에 투명전극코팅을 하거나 투명전극코팅된 글라스를 부착하면 전자파에 의한 통신방해도 차단시킬 수 있다.The elliptical beam forming lens 32a focuses an infrared pulse signal and sharply forms a light receiving pattern to reduce space loss generated during optical communication. As a result, the installation interval of the first transceivers 30a to 30m increases, thereby reducing the number of installations of the first transceivers 30a to 30m as well as the influence of infrared interference waves caused by the fluorescent lights installed on the tunnel walls. Can be minimized. In addition, when the transparent electrode coating or the transparent electrode coated glass is attached to the lens 32a, it is possible to block communication by electromagnetic waves.

또한, 통신프로세서(34)는 상기 수신모듈(31)을 통해 수신된 데이터와 제1 송수신기의 상태정보를 중계장치(10)로 전송하고, 중계장치(10)로 부터 전송된 각종 제어명령에 따라 제1 송수신기의 동작을 제어하며 아울러 해당 제어명령을 후단의 제1 송수신기로 중계한다.In addition, the communication processor 34 transmits the data received through the receiving module 31 and the state information of the first transceiver to the relay device 10 and according to various control commands transmitted from the relay device 10. The operation of the first transceiver is controlled and the control command is relayed to the first transceiver of the subsequent stage.

In the present embodiment, the infrared wireless LAN is formed by using the second transceivers 40b and 40c installed on the front and rear surfaces of each of the electric vehicles 20a to 20m, and the servers 21 installed in the electric vehicles 20a to 20m are mutually connected. Connected.
다음에는 상기와 같이 구성된 본 발명에 따른 정보전달 시스템의 동작방법을 상세히 설명한다.Next will be described in detail the operation method of the information delivery system according to the present invention configured as described above.
지하철 역사내에 설치된 중계장치(10)는 인터넷망을 통해 취합, 편집된 동영상 정보신호나 인터넷 방송국에서 제공하는 국내외 주요뉴스, 주식정보, 생활정보, 광고 등의 방송신호중 어느 하나를 선택적으로 출력하게 되는데, 이와같이 출력된 동영상 정보신호는 인터페이스부(13,14)를 통해 지하철 터널벽에 설치된 제1 송수신기(30a∼30m)로 전송된다.The relay device 10 installed in the subway station selectively outputs any one of the video information signals collected and edited through the Internet network or broadcast signals such as domestic and overseas major news, stock information, life information, and advertisements provided by an internet broadcasting station. The video information signal output in this way is transmitted to the first transceivers 30a to 30m installed in the subway tunnel wall through the interface units 13 and 14.
즉, 중계장치(10)에서 출력되는 동영상 정보신호가 제1 송수신기(30a)로 전송되면 리피터(35)가 이를 증폭하여 후단의 제1 송수신기(30b)로 전송하고 이와같은 방식으로 동영상 정보신호를 케이블로 연결된 마지막 제1 송수신기(30m)까지 신호의 손실없이 전송하게 된다.That is, when the video information signal output from the relay device 10 is transmitted to the first transceiver 30a, the repeater 35 amplifies it and transmits the video information signal to the first transceiver 30b at a later stage. The first first transceiver 30m connected by the cable is transmitted without loss of signal.
한편, 제어차량인 전동차(20a)에 장착된 제2 송수신기(40a)의 송신모듈(41)은 서버(21)의 제어에 따라 위치신호를 출력하게 되는데, 이와같이 출력된 위치신호는 제1 송수신기(30a∼30m)의 수신모듈(31)에 의해 수신된다. 수신된 신호의 수신강도가 기설정된 신호값 보다 크면 해당 제1 송수신기의 수신강도 검출부(33)가 절환스위치(SW)를 스위칭시키게 된다.On the other hand, the transmission module 41 of the second transceiver 40a mounted on the electric vehicle 20a, which is a control vehicle, outputs a position signal under the control of the server 21, and the output position signal is the first transceiver ( 30a to 30m). When the received strength of the received signal is greater than the preset signal value, the received strength detection unit 33 of the first transceiver switches the switching switch SW.
이에따라, 중계장치(10)에서 출력된 방송신호가 절환스위치(SW)를 통해 송신모듈(32)로 인가되며, 송신모듈(32)은 인가되는 방송신호인 디지털 신호에 따라 850∼900nm의 파장을 갖는 적외선 펄스신호를 발생시켜 타원빔 형성용 렌즈(32a)를 통해 전동차(20a)에 설치된 제2 송수신기(40a)로 전송하게 된다.Accordingly, the broadcast signal output from the relay device 10 is applied to the transmission module 32 through the switch SW, and the transmission module 32 emits a wavelength of 850 to 900 nm according to the digital signal which is the applied broadcast signal. An infrared pulse signal is generated and transmitted to the second transceiver 40a installed in the electric vehicle 20a through the elliptical beam forming lens 32a.
상기와 같이 전송된 적외선 펄스신호는 제2 송수신기(40a)의 수신모듈(42)을 통해 수신되어 서버(21)로 인가된다. 따라서, 서버(21)는 이를 각 단말기(22a∼ 22n)로 출력하여 승객에게 동영상 정보를 제공하게 된다. 또한, 상기 서버(21)는 전동차(20a)의 후면에 부착된 제2 송수신기(40b)와 다음 전동차의 전면에 부착된 제2 송수신기(40c)를 통해 다음 전동차의 서버(21)로 해당 동영상 정보를 전송하고 이와같은 방식으로 동영상 정보를 마지막 전동차까지 전송하게 되는데, 각 전동차에 장착된 서버(21)는 수신되는 동영상 정보신호를 각 차량의 내부에 부착된 단말기(22a∼22n)로 출력하여 디스플레이하게 된다.The infrared pulse signal transmitted as described above is received through the receiving module 42 of the second transceiver 40a and applied to the server 21. Therefore, the server 21 outputs it to each terminal 22a to 22n to provide moving picture information to the passenger. In addition, the server 21 through the second transceiver 40b attached to the rear of the electric vehicle 20a and the second transceiver 40c attached to the front of the next electric vehicle, the corresponding video information to the server 21 of the next electric vehicle. In this way, the video information is transmitted to the last electric vehicle in this way, and the server 21 mounted in each electric vehicle outputs the received video information signal to the terminals 22a to 22n attached to the inside of each vehicle to display. Done.
