Abstract

본 발명은 엘리베이터 위치검출기의 고장유무를 엘리베이터 정치중에서 확인할 수 있도록 하여 엘리베이터 운전의 안정성을 확보할 수 있도록 한 엘리베이터의 위치검출기 고장유무 검출회로 및 제어방법에 관한 것으로, 위치검출기(10)의 고장유무 체크용 신호를 출력하기 위한 체크단자(CHK)와, 저항(R6,R7) 및 콘덴서(C1)로 이루어진 시간지연부(30) 및 상기 체크단자(CHK)를 통해 출력된 체크신호에 의해 출력단자(+OUT)의 신호상태를 파악할 수 있도록 한 트랜지스터(TR3)를 포함하도록 구성하여 엘리베이터가 고속자동중이 아니거나, 엘리베이터에 이상이 발생하였거나, 엘리베이터가 도어 존에 위치해 있지 않거나, 완전정지 상태가 아니면, 위치검출기의 고장 검출을 행하지 않고, 초기화를 실행하고, 상기 각 조건의 반대조건일 경우에는 체크를 실행하도록 함으로서, 위치 검출기의 고장으로 인한 탐승자의 추락사고를 미연에 방지할 수 있는 특징이 있다.The present invention relates to a position detector failure detection circuit and a control method of an elevator in which stability of an elevator operation can be ensured by confirming whether or not a failure of the elevator position detector can be confirmed in an elevator position. A time delay unit 30 composed of resistors R6 and R7 and a capacitor C1 and a check signal output through the check terminal CHK are connected to the output terminal CHK through a check terminal CHK for outputting a check signal, (TR3) so that the signal state of the elevator (+ OUT) can be grasped, so that the elevator can not be automatically operated at high speed, an elevator has an error, the elevator is not located in the door zone, Otherwise, the initialization is executed without detecting the failure of the position detector. If the condition is the opposite of the above conditions, the check is executed Locking of the position detector can prevent an accidental crash of the loser due to the failure of the position detector.

Claims

A check terminal CHK for outputting a signal for checking the presence / absence of failure of the position detector 10; A time delay unit 30 composed of resistors R6 and R7 and a capacitor C1; And a transistor TR3 for detecting a signal state of the output terminal (+ OUT) by a check signal outputted through the check terminal (CHK).

A step (step 1) of judging whether or not the elevator is in high speed automatic operation; (Step 2) of determining if an elevator abnormality has occurred, if it is judged to be high speed automatic driving; Determining whether the elevator is located in a door zone (step 3) if the elevator is not abnormal; A step (step 4) of judging whether the elevator is in a complete stop state if the elevator is located in the coexistence; Judging whether the check has been performed (step 5) if it is in the completely stopped state; If not performed, outputting a check signal via the check terminal CHK (step 6); A step in which the check signal is delayed through the time delay unit 30 (step 7); Receiving a signal applied through an output terminal (+ OUT) (step 8); Determining whether the signal state of the output terminal (+ OUT) is high (step 9); And stopping the operation of the elevator by recognizing that the operation of the position detector (10) is failed when the signal is a high signal in the step (9) (step 10).
