エレベータの制御システム
Document Type and Number:
Japanese Patent JP7021659
Kind Code:
B2
Abstract:
To provide a technique capable of detecting positional deviation caused in a car door of an elevator with a simple structure.SOLUTION: An elevator control system includes an output device for outputting a signal according to the rotation amount of a driving motor for opening/closing a car door, an imaging device for photographing the door, and a door control device for controlling the opening/closing of the door. The door control device includes an estimation processing unit, a drive processing unit, an image processing unit, and a detection processing unit. The estimation processing unit derives an estimated position of the door according to a signal output by the output device. The drive processing unit controls the driving motor based on the estimated position derived by the estimation processing unit. The image processing unit derives an actual position of the door by using a photographed image of the door acquired by the imaging device. The detection processing unit detects the deviation of the estimated position from the actual position derived by the image processing unit.SELECTED DRAWING: Figure 1
