원거리 적외선 송수신기(100)는 도로변의 가로등(101) 또는 전주등에 설치되고, 열에 민감한 형태의 초전형센서와 차량송수신기(200)에서 송신되는 ID를 수신하는 양자형 센서를 내장하게 되며, 수집된 교통정보를 광케이블(300)을 이용하여 교통정보 종합상황실(600)로 송신하는 한편 교통정보 종합상황실(600)로부터 송신된 교통정보를 발신하게 된다.The far-infrared transceiver 100 is installed on a street lamp 101 or a pole of a roadside, and incorporates a pyroelectric sensor of a heat-sensitive type and a quantum sensor that receives an ID transmitted from the vehicle transceiver 200, and collects traffic. The information is transmitted to the traffic information general situation room 600 using the optical cable 300, and the traffic information transmitted from the traffic information general situation room 600 is transmitted.
상기 원거리적외선송수신기(100)는 사용전원공급이 원활한 곳에서는 상용전원을 사용하고 그렇지 않은 경우는 태양전지를 이용하도록 하며, 24MHz 펄스신호로 고출력 송신시켜 송신거리를 증가(주간 100m, 야간 200m)시키고, 수신센서 통달거리를 길게 하기 위하여 촛점거리 15mm의 20배율 확대용 렌즈를 사용한다.The far-infrared ray transmitter 100 uses commercial power when the power supply is smooth, otherwise it uses solar cells, and increases the transmission distance by transmitting high power with a 24MHz pulse signal (100m per week, 200m at night). In order to increase the receiving sensor communication distance, a 20x magnification lens with a focal length of 15mm is used.
원거리적외선송수신기(100)는 가로등(101) 및 전주설치 간격인 50∼100m 또는 정보수집에 문제가 되지 않는 간격으로 설치하며, 가로등 또는 전주가 설치되지 않은 도로에서는 적절한 지주대를 설치하여야 한다.The far-infrared ray transmitter 100 is installed at a distance of 50 to 100 m, which is a distance between the street lamp 101 and the pole poles, or at intervals that do not cause problems in collecting information.

차량에 탑재되는 차량송수신기(200)는 차량출고시 지정되는 ID를 시동을 거는 순간부터 적외선으로 송신시키게 되고, 원거리적외선송수신기(100)로부터 송신된 교통정보를 수신하여 차량에 탑재된 네비게이터 등의 표시장치에 교통정보등을 표시시키게 된다.The vehicle transmitter 200 mounted on the vehicle transmits the ID specified at the time of starting the vehicle to the infrared from the moment of starting the vehicle, and receives the traffic information transmitted from the far infrared ray transmitter 100 to display a navigator mounted on the vehicle. Traffic information is displayed on the device.
차량에 탑재되는 차량송수신기(200)는 시동시부터 자신의 ID를 적외선으로 송신시키게 되고, 상기 차량송수신기(200)에서 송신하는 ID를 예를 들면 도 5 에 도시된 바와 같이 구성하여, 각각의 차량마다 차량번호와 같이 고유의 ID를 송신하도록 하되, 상기 ID는 일반인이 조작하거나 훼손시키지 않도록 별도의 장치를 보완시키게 된다.The vehicle transceiver 200 mounted on the vehicle transmits its ID in infrared rays from the time of starting, and configures the ID transmitted by the vehicle transmitter 200 as shown in FIG. Each unique ID, such as a vehicle number, is transmitted, but the ID supplements a separate device so that the general public does not manipulate or damage the ID.
상기 차량송수신기(200)에서 적외선 송신된 ID는 원거리 적외선송수신기(100)에서 수신하게 되고, 상기 원거리 적외선 송수신기(100)에서 수신한 차량 ID는 적외선송수신기(100)를 나타내는 고유의 ID와 함께 광케이블(300)을 통하여 교통정보 종합상황실(600)로 송신한다.The ID transmitted from the vehicle transmitter 200 by infrared rays is received by the far-infrared transmitter 100, and the vehicle ID received by the far-infrared transceiver 100 is combined with a unique ID indicating the infrared transmitter 100 by using an optical cable ( 300 is transmitted to the traffic information general situation room (600).
