Energy-saving type high-reliability floor traffic light system

摘要

The present invention includes a plurality of display units installed on the floor to emit light in conjunction with a crosswalk traffic light; A pedestrian sensor installed to detect pedestrians in a crosswalk or near the crosswalk and output a detection signal; and a traffic light control unit that receives a detection signal from the pedestrian sensor and controls the operation or light intensity of the display unit. According to the present invention, even if some of the plurality of display units are not connected to power due to a malfunction, the remaining display units operate by normal power supply, thereby increasing the reliability of operation, and detecting malfunctions of the display units through temperature detection of the display units. By making it easy to check from a remote location, it provides convenience in maintaining and managing the display unit, and consumes energy for the display unit by detecting the movement of people or objects around it and controlling the operation of the display unit according to the measurement of illuminance. By reducing , it has the effect of promoting economical operation.
