HOME > 제품소개 > 교통신호제어기 Traffic information processing It exchanges information with the central control unit, analyzes the information gathered from signal control unit, MMI and each unit of extension board, and controls the display status of traffic signals Communications function It is used to send and receive information to/from a traffic information center, receive traffic parameters periodically, upload and download database, and exchange onsite information including signal status, controller status, and collected traffic information. Database management It manages signal control by use of both database also available to traffic control center and internal database. Vehicle sensor It is a device to sense the passage of vehicles by use of loop coils laid on roads. It has three modes of output, sensitivity, automatic frequency, and correction function. Extension slot function (optional) It is used to control input of pedestrian signals, traffic signals of the section in which the direction of traffic streams for each time zone is reversed, and reversible lanes, and collect and analyze information on traffic streams through interface with image sensors. Manual input processing It exchanges data with the main control unit and controls the display status of signals after analyzing the information collected from each unit including signal control unit, MMI, vehicle sensor and extension board. Signal conflict and 등기출력 detection It detects the electric current and voltage on 등기부 within LSU circuit, the status of 등기 output on controller based on the signals, and the signal conflict. Flasher unit When there occurs a conflict on the signal lighting status of signal control unit or a conflict on the input voltage, it flickers red signal after it receives a flickering order from CPU. Fixed cycle display It is the final mode performed in SCU when MCU hardware is out of order. It is used to proceed with display at a fixed cycle. LSU It is a switch gear for signal lamp. Six drive circuits are built in each unit to open and shut 48 등기 circuits. Lighting controller It controls the brightness of signals by controlling electric wave and half wave on the basis of AC(60Hz).
