An apparatus and method for measuring train movement information are disclosed. The apparatus for measuring train movement information according to the present invention includes: a distance measuring unit for measuring a distance to a train; and a movement information measuring unit for sampling the distance measured by the distance measuring unit, calculating average acceleration at each sampling point using a plurality of distances which are sampled, estimating the acceleration and deceleration states of the train by analyzing the calculated average acceleration, and then measuring at least one of the acceleration, speed, and distance of the train according to the estimated acceleration and deceleration states of the train. Accordingly, the present invention can accurately measure the acceleration, speed, and distance of the train which moves in real time.
열차 이동정보 측정 장치 및 방법이 개시된다. 본 발명의 열차 이동정보 측정 장치는 열차와의 거리를 측정하는 거리 측정부; 및 상기 거리 측정부에 의해 측정된 거리를 샘플링하고, 샘플링된 복수 개의 거리를 이용하여 각 샘플링 시점에서의 평균 가속도를 계산하며, 계산된 평균 가속도를 분석하여 열차의 가감속 상태를 추정한 후, 추정된 열차의 가감속 상태에 따라 열차의 가속도, 속도 및 거리 중 적어도 하나를 측정하는 이동정보 측정부를 포함하는 것을 특징으로 한다.
