Abstract

본 발명은 엘리베이터의 동기위치 검출장치에서 출력되는 펄스를 근거로 하여 엘리베이터의 동기위치를 파악하는 기술에 관한 것으로, 종래의 엘리베이터에 있어서는 가속 등속구간에서의 동기위치 오차와 감속구간에서의 동기위치 오차간 편차만큼 정지층 도착시 승강장 바닥과 카 바닥간에 위치오차가 발생되는 결함이 있고, 동기위치값 보성기술에서는 슬립 거리량이 포함되어 있어 이에 따른 감속 후반부에 등속구간이 존재하게 되고, 이로 인하여 운전효율이 저하되는 결함이 있었다. 따라서, 본 발명은 이를 해결하기 위하여, 카(2) 주행시 가속 등속구간, 감속구간별로 동기위치 오차량을 검출하고, 가속, 등속구간의 동기위치 오차와 감속구간에서의 동기위치 편차량을 카내 하중, 주행방향, 출발 및 정지층 위치별로 데이타 베이스를 구축하고, 이렇게 구축된 데이타 베이스를 근거로 속도패턴 변경시 편차량을 반영하여 목적층에 도착시 승강장 바닥과 카 바닥간의 위치오차를 최소화 하며, 동기위치를 보정함에 있어서 감속 개시 시점 연산시 데이타 베이스에 저장되어 있는 슬립거리를 이용하여 서비스 효율을 한층 향상시킬 수 있도록 하였다.The present invention relates to a technique for grasping a synchronous position of an elevator on the basis of a pulse output from an elevator synchronous position detecting device. In a conventional elevator, a synchronous position error in an acceleration constant velocity section and a synchronous position error There is a defect that a position error occurs between the floor of the landing platform and the floor of the car when the stationary floor arrives by the deviation amount, and the slip distance amount is included in the synchronous position value support technique, so that the constant speed section exists in the latter half of the deceleration, There was a defective defect. Therefore, in order to solve this problem, in order to solve this problem, a synchronous position error is detected for each of the acceleration constant velocity section and the deceleration section when the car 2 is traveling, and the synchronous position error in acceleration, constant velocity section, , The direction of travel, the location of the starting and stopping layers, and minimizes the position error between the landing floor and the car floor when arriving at the destination floor by reflecting the deviation in the speed pattern change based on the constructed database, In the correction of the synchronous position, the service efficiency is further improved by using the slip distance stored in the database during the deceleration start time calculation.
