The present invention relates to a control system of a display means for a crosswalk. Since the road sign is provided with a photovoltaic power generation means and a wireless communication means so as to not require a connection of separate power lines and communication lines, the cost and installation period due to wiring work can be reduced. When a pedestrian leaves the crosswalk while crossing the crosswalk, the expected crossing time is derived from the location, movement direction, and movement speed of the pedestrians before leaving the crosswalk, and the lighting time of road signs is extended, so that a collision between a pedestrian and a vehicle can be prevented by preventing a vehicle from entering until a pedestrian who has left from the crosswalk completes the crossing. A controller is configured to output signals with appropriate signal strength according to a distance from each road sign, and not only can communication failure due to signal interference be prevented in advance, but safety of the power supply and communication can be increased by reducing unnecessary power consumption.

    본 발명은 도로표지병이 태양광 발전수단 및 무선통신수단을 구비하여 별도의 전력선 및 통신선을 연결하지 않아도 되기 때문에 배선 작업에 의한 비용 발생 및 설치 기간을 절감시킬 수 있으며, 횡단보도를 횡단하는 도중에 보행자가 횡단보도를 이탈하였을 때 횡단보도를 이탈하기 전 보행자의 위치, 이동방향 및 이동속도를 통해 예상 횡단시간을 도출하여 도로표지병의 점등시간을 연장시켜줌으로써 횡단보도를 이탈한 보행자가 횡단을 완료할 때까지 차량이 진입하는 것을 방지하여 보행자와 차량의 충돌사고를 방지할 수 있고, 컨트롤러가 각 도로표지병과의 이격된 거리에 따라 적정신호세기로 신호를 출력하도록 구성됨으로써 신호간섭으로 인한 통신장애를 미연에 방지할 수 있을 뿐만 아니라 불필요한 전력소모를 절감시켜 전원 공급 및 통신의 안전성을 현저히 높일 수 있는 횡단보도용 표출수단의 제어시스템에 관한 것이다.
