A variable maximum speed limit display panel and a variable maximum speed display speed information system are provided to calculate the current speed of a vehicle by using a radar wave, change the speed limit of the vehicle according to a set time or illuminance by receiving GPS time information or an illuminance value of an illuminance sensor, display the speed limit of the vehicle and the current speed of the vehicle on an LED, and change the speed limit of the vehicle according to various environmental conditions of rainfall, visible distance, and black ice. According to the present invention, the maximum speed suitable for a set time is displayed on the LED by differently defining the speed limit of the school zone, thereby being efficient in terms of the moving efficiency of the vehicle and smoothly flowing traffic.
가변형 최고속도 제한 표시판 및 가변형 최고속도 표시용 과속 정보 시스템은 레이더파를 이용하여 차량의 현재 속도를 계산하고, GPS 시간 정보이나 조도센서의 조도값을 받아서 설정된 시간이나 조도에 따라 차량 제한 속도를 변경하여 차량 제한 속도와 차량의 현재 속도를 LED에 표시하며, 강수량, 가시거리, 블랙아이스의 다양한 환경 조건에 따라 차량 제한 속도를 변경한다. 본 발명은 스쿨존의 속도 제한을 다르게 규정함에 따라 설정된 시간에 맞는 최고 속도를 LED에 표시하여 차량의 이동 효율 측면에서 효율적이며, 이에 따라 교통 흐름을 원활히 하는 효과가 있다.
