Device for sensing the movement of the wings of an automatic revolving door

Abstract

The invention relates to a device for sensing and protecting the movement of a leaf of an automatic revolving door, which comprises a sensor mechanism and a door control device communicating with the sensor mechanism, said sensor mechanism having sensor unit and / or a sensor unit on the door leaf opposite the hinge. A corresponding sensor unit includes an at least substantially planar distance scanner. The sensor system and / or the door control device are embodied in such a way that during a corresponding automatically implemented learning cycle during the opening and / or closing cycle of the door leaf, the respective sensor unit is on the hinge side or hinge side respectively at successive door opening angles. The distance to the surroundings of the door leaf is measured in the opposite plane, determined from the measured values ​​obtained in different planes as a function of the distance to the surroundings measured in different planes as a function of the door opening angle and as a function of the door opening angle A three-dimensional image of the surroundings and the thus determined three-dimensional image of the surroundings is stored.

Description

technical field [0001] The invention relates to a device for sensing and protecting the movement of a leaf of an automatic revolving door, said device having a sensing mechanism and a door control device communicating with said sensing mechanism, said sensor mechanism comprising a A sensor unit on the door leaf and / or a sensor unit arranged on the door leaf opposite the hinge. Background technique [0002] Automatic revolving doors with a motorized drive, in particular an electric drive, are generally known. The automatic revolving door always facilitates door movement when manual manipulation is cumbersome or laborious. [0003] In order to make an automated door leaf safe when opening and closing it is also known to sense the movement of the guard leaf. For this purpose, presence sensors are mounted on the door leaf on the hinge side and on the hinge-opposite side, moving together with the door leaf. If a person enters the detection range of the sensor arranged on the h...

Problems solved by technology

The disadvantage of such conventional implementations is the small resolution

[0011] The hitherto common devices for sensing the leaf movement of automatic revolving doors or the hitherto usual sensing and guarding of automatically revolving leaf doors have the following disadvantages: the detection range of the sensor is fixed and the sensor has to be parameterized
