The present invention relates to a method for reducing an accumulated error of an elevator moving distance through a moving average filter and, more particularly, to a method for correcting a moving distance value calculated by an acceleration sensor when an elevator moves up and down, and calculating an accumulated moving distance of the elevator with the corrected value. Provided is a method of reducing an accumulated error of an elevator moving distance by applying a moving average filter, which comprises: an initialization step of generating an array in a memory (400) by receiving the number of floors of the elevator from a user and calculating the number of cases for a movement section, and setting an initial value to 0; an integral step of integrating an acceleration sensor value provided by an acceleration sensor (100) to calculate a speed; a starting step of measuring, if the speed value is 0 in the integral step, an air pressure sensor value (A) in an air pressure sensor (500); an operation step of integrating, if the speed value is not 0, the speed value to calculate and accumulate a distance value, and calculating a moving distance until the speed value becomes 0; and an arrival step of comparing the measured value (B) of the air pressure sensor (500) when the speed value is changed to 0 with the measured value (A) of the starting step, storing the comparing result, and storing the moving distance value of the operation step in the operation step (raw).

    본 발명은 이동평균필터를 통한 승강기 이동거리 누적오차 감소 방법에 관한 것으로, 더 상세하게는 승강기가 상하로 이동할때 가속도센서에서 산출되는 이동거리값을 이동평균필터로 보정하고 보정된 값으로 승강기의 누적 이동거리를 계산하여 방법에 관한 것이다. 사용자에 의해 승강기 층수를 입력받아 이동구간에 대한 경우의 수를 계산하여 메모리(400)에 배열을 생성하고 초기값을 0으로 설정하는 초기화단계와 가속도센서(100)에서 제공하는 가속도센서값을 적분하여 속도를 계산하는 적분단계와 적분단계에서 속도값이 0이면 기압센서(500)에 기압센서 값을 측정(A)하는 출발 단계와 속도값이 0이 아닌 경우 속도값을 적분하여 거리값를 계산하여 누적하고 속도값이 0이 될때까지 이동거리를 계산하는 운행단계와 속도값이 0인 상태로 변경되었을 때 기압센서(500) 측정값(B)과 상기 출발단계 측정값(A)을 비교하여 저장하고, 운행단계의 이동거리값을 운행단계(raw)에 저장하는 도착단계와 이동평균필터를 적용하여 승강기 이동거리의 누적오차를 감소시키는 방법을 제공한다
