Apparatus for control a sliding door

Abstract

The present invention relates to an apparatus for controlling a sliding door, the apparatus allowing a user using a door configured to slide automatically to safely move to the inside and outside of the door. The apparatus comprises: a door movement detection unit configured to detect movement information of the sliding door from an image of a camera that captures an image of the inside of the sliding door; a moving object movement detection section configured to detect movement information of the moving object inside and outside the sliding door from the video image; a track intersection object detection section configured to detect presence information of an intersection object that intersects a track of the sliding door from the video image; and a door opening / closing control section configured to combine the information detected from each of the detection sections to control opening / closing of the sliding door.

Description

technical field [0001] The invention relates to the opening and closing control of a sliding door. More particularly, the present invention relates to a device configured to control opening and closing of a sliding door so that a user using an automatic sliding door can safely move to the inside and outside of the door. Background technique [0002] In sliding doors used for elevators, subways, etc., a method of controlling opening and closing of the sliding doors by sensing obstacles, getting on and off of passengers, etc. through various obstacle sensors using microwaves, lasers, etc. is generally used. [0003] In a system configured to control the opening and closing of a sliding door using an obstacle sensor, since the obstacle sensor is generally located near the focal point of the sliding door positioned in the vertical direction, and thus cannot sense passengers and pets, so accidents often occur. [0004] In particular, in a system configured to control the openin...

AI Technical Summary

Problems solved by technology

[0008] When an object other than a leash is placed on the ground across the track of the sliding door, since the sliding door repeatedly opens and closes regardless of whether it senses an obstacle, a malfunction of the sliding door may occur

[0009] Furthermore, although the sliding door is controlled to close repeatedly when the object is an immovable object and thus determined not to be moving by the system using the imagery, failure of the sliding door may occur due to the sliding door being repeatedly opened by an object placed across its track
