Abstract

본 발명의 엘리베이터 도어의 억지열림 방지방법은 엘리베이터의 케이지를 승객이 도어를 강제로 개방시킬 경우에 도어가 열리지 않도록 하는 것으로서 종래에는 케이지의 운행시 모터에 지속적으로 전원을 공급함으로써 모터의 사용수명을 단축시키고, 승객이 도어를 강제로 개방시킬 경우에 개방되지 않도록 하는 수단이 구비되어 있지 않아 안전사고의 발생위험이 높았다.The method of preventing the opening of the elevator door of the present invention is to prevent the door from opening when the cage of the elevator is forcibly opened by the passenger. Conventionally, the service life of the motor is continuously provided by continuously supplying power to the motor when the cage is running. The risk of accidents was high because there was no means to shorten and prevent the passengers from opening when the door was forcibly opened.

본 발명은 도어(1)(1A)의 폐쇄완료시 도어의 이동에 따라 발생되는 펄스신호가 입력되는 지를 판단하는 제1과정과, 상기 제1과정에서 펄스신호의 입력시 이를 카운트하여 도어의 열림정도를 판단하는 제2과정과, 상기 제2과정에서 판단한 도어의 열림정도가 미리 설정된 값 이상일 경우에 도어를 강제로 폐쇄시키는 제3과정으로 제어하여 엘리베이터의 도어를 강제로 개방시켜도 열리지 않아 안전사고의 발생을 미연에 방지하며, 모터 및 제어기의 사용수명을 연장한다.According to the present invention, a first process of determining whether a pulse signal generated according to the movement of the door is input when the door (1) (1A) is closed and the door is opened by counting it when the pulse signal is input in the first process. The second process of judging the degree and the third process of forcibly closing the door when the opening degree of the door determined in the second process is more than a preset value are controlled so that the door of the elevator does not open even if it is forcibly opened. This prevents the occurrence of oil and prolongs the service life of the motor and controller.
