Title:
CRIME PREVENTIVE OPERATION DEVICE FOR ELEVATOR
Document Type and Number:
Japanese Patent JP2586266
Kind Code:
B2
Abstract:
PURPOSE: To surely prevent crimes and reduce the installation cost of an elevator without installing a window at a getting-on field by installing a means for correcting an aimed floor to the contiguous floor when a waiting passenger detecting means detects that a waiting passenger is present at the getting-on field on an aimed floor.
CONSTITUTION: In the theft-preventive mode time region at present (S1), the detection value of a waiting passenger detecting sensor at each elevator getting-on field is inputted (S2), and it is judged that a waiting passenger detecting sensor at the getting-on field on an aimed floor detects a waiting passenger or not (S3). When no waiting passenger is detected, it is judged that the need of theft-preventive operation is unnecessary, and the ordinary operation control is carried out. Further, if it is judged that a waiting passenger is present at the elevator getting-on field on the aimed floor, it is judged if the aimed floor registered by the cage call is the uppermost floor or not (S4), and if the aimed floor is the uppermost floor, the aimed floor is corrected by the subtraction by -1 (S5). When the aimed floor is not the uppermost floor, correction is performed by adding +1 (S6). Then, a cage position display device at the getting-on field where a waiting passenger is present is put OFF (S7).
