CONTROL SYSTEM OF ELECTRIC BULLETIN BOARD HAVING A TRAFFIC INFORMATION DISPLAYING FUNCTION USING TPEG SIGNAL AND CONTROLLING METHOD THEREFOR

摘要

PURPOSE: An electronic display board control system with a traffic information display function using transport protocol expert group (TPEG) signals and a control method thereof easily recognize unexpected accidents or congestion information through a high-quality screen by displaying the unexpected accidents or the congestion information included in TPEG information on the LED electronic display board. CONSTITUTION: A piezoelectric circuit (3) is buried beneath a road (1) and generates piezoelectric energy according to the weight of a moving vehicle. A display control driving unit is driven by the piezoelectric energy generated from the piezoelectric circuit and displays traffic information separated from a received TPEG signal on an electronic display board member (4) including LEDs.
