The present disclosure relates to a variable speed limit sign control system enabling a variable speed limit sign to respond to the change of a weather environment. As a first invention, provided is a variable speed limit sign control system responding to an abnormal weather environment, the variable speed limit sign control system including: a variable speed limit sign which is installed on a road and is configured to control a light emission amount of an LED; a weather situation measuring unit which measures the weather state of the road and transmits the weather state; a control server which receives a signal transmitted from the weather situation measuring unit and outputs a control signal of the light emission amount of the LED; and a signs controller which changes the light emission amount of the LED of the variable speed limit sign according to the signal of the control server. Accordingly, the preset invention can contribute to traffic safety by quickly controlling the brightness of the sign.

    본 개시(Disclosure)는, 가변속도제한 표지판을 기상 환경 변화에 따라 대응하는 가변속도제한 표지판 제어 시스템에 관한 것으로서, 도로 상에 설치되고, LED 발광량 제어가 가능하도록 이루어진 가변속도제한 표지판과; 도로의 기상 상태를 측정하여 전송하는 기상상황 측정부와; 상기 기상상황 측정부로부터 전송된 신호를 입력받아 LED 발광량 제어 신호를 출력하는 제어 서버와; 상기 제어 서버의 신호에 따라 상기 가변속도제한 표지판의 LED 발광량을 변경하는 표지판 콘트롤러를 포함하는 이상기상환경에 대응하는 가변속도제한 표지판 제어 시스템을 제1 발명으로 제공한다.
