The present invention relates to a method for calculating and compensating the uncertainty of a train position in a train control system based on radio communications, comprising the steps of: counting output pulses received by first and second tachometers prepared inside a train car to calculate and compare measurement errors of the first and second tachometers d_(e1)(i) and d_(e2)(i) using the number of pulses, p_1 and p_2, thereby determining an over-reading distance error value and an under-reading distance error value; obtaining a cumulative over-reading distance error, O_e(i) and a cumulative under-reading distance error, U_e(i); and using the same to obtain an over-reading distance error per unit pulse, PO_e and an under-reading distance error per unit pulse, PU_e, to calculate a confidence interval of the train head, DCI_h, and a confidence interval of the train rear, DCI_r.

    본 발명은 무선통신기반 열차제어시스템에서 열차 위치불확실성 계산 및 보상 방법에 관한 것으로; 열차의 차상에 구비되는 제1 및 제2 타코미터로부터 수신된 출력 펄스(pulse)를 카운트하여 펄스수 p과 p를 이용해 제1 및 제2 타코미터의 측정오차 d(i) 및 d(i)를 계산하고 비교하여 오버-리딩 거리오차 값과 언더-리딩 거리오차 값을 선택하고, 누적된 오버-리딩 거리오차 값 O(i)와 언더-리딩 거리오차 값 U(i)를 구하고, 이를 이용해 단위 펄스당 오버-리딩 거리오차 PO와 언더-리딩 거리오차 PU를 구한 후 열차 전두부의 신뢰구간 DCI및 후미부에 대한 신뢰구간 DCI을 계산하는 무선통신기반 열차제어시스템에서 열차 위치불확실성 계산 및 보상 방법을 제공한다.
