The present invention relates to a protection system for traffic disadvantaged using radio frequency-ranging, which provides a vehicle intending to pass the crosswalk with the access of a pedestrian intending to walk a crosswalk so that a traffic accident which occurs in a crosswalk can be prevented beforehand. The protection system comprises: an RF smart tag (100) which is carried by a pedestrian waiting to cross a crosswalk and, when receiving an LF confirmation signal transmitted from the outside, transmits an RF response signal to the outside; a vehicle warning part (300) which is provided in a vehicle and, when receiving a warning signal transmitted from the outside, outputs a warning message to warn a driver; and a warning device (400) which is installed adjacent to the crosswalk to transmit the LF confirmation signal to the outside so as to confirm the pedestrian intending to pass the crosswalk and, when receiving the RF response signal transmitted from the RF smart tag (100), confirms the distance of the pedestrian on the basis of the received RF response signal, and transmits each different warning signals to the vehicle warning part (300) according to the confirmed distance of the pedestrian. The vehicle warning part (300) outputs a warning message corresponding to the received warning signal when receiving a specific warning signal.

    본 발명은 횡단보도를 보행하고자 하는 보행자의 접근을 횡단보도를 통과하고자 하는 자동차에 제공하여 횡단보도에서 발생되는 교통사고를 미연에 방지할 수 있는 무선 주파수 레인징을 이용한 교통약자 보호 시스템에 관한 것이다. 본 발명의 특징은, 횡단보도를 횡단하기 위해 대기하는 보행자가 휴대하고, 외부로부터 전송되는 LF확인신호를 수신하면 RF답신신호를 외부로 전송하는 RF스마트태그(100)와, 자동차에 구비되어 외부로부터 전송되는 경고신호를 수신하면 운전자에게 경고메시지를 출력하여 경고하는 자동차경고부(300)와, 횡단보도에 근접되게 설치되어 횡단보도를 통과하고자 하는 보행자를 확인하기 위해 LF확인신호를 외부로 전송하고, RF스마트태그(100)부터 전송되는 RF답신신호를 수신하면 수신된 RF답신신호를 근거로 보행자의 거리를 확인하고 확인된 보행자의 거리에 따라 각기 다른 경고신호를 자동차경고부(300)로 전송하는 경고장치(400)를 포함하고, 자동차경고부(300)는 특정 경고신호를 수신하면 수신된 경고신호에 해당하는 경고메시지를 출력한다.
