Door system with noncontact access control and noncontact door operation

Abstract

The door system consists of a door frame (1) and at least one door leaf, (2) as well as a door drive (3) with a control unit. The door leaf (2) is equipped with a hand vein scanner (4) for detecting the hand vein profile when a hand is held a distance in front of the hand vein scanner (4) for the purpose of recognizing the user. A programmable computer unit (5) with a memory element, in which a plurality of user hand vein profiles can be stored, is housed in the interior of the door leaf (2). A hand vein profile is compared to the hand vein profiles stored in the memory element of the computer unit (5) and, depending on a match, the door is opened or not. The computer unit (5) is programmed and supplied with power via a network interface (10) that terminates in the edge (8) of the door leaf or the peripheral area (9) and is the only interface between the door leaf (2) and the door frame (1), other than the signal cable (6) for the control unit for the door drive (3). The computer unit (5) can be programmed by temporarily connecting an external computer (7) to this network interface (10). The network interface (10) is also used for connecting a power supply for the computer device (5).

Description

technical field [0001] The present invention relates to a door system that allows contactless access control and also allows contactless door operation. Background technique [0002] There are many different types of doors or options for doors that use other unlocking methods instead of the traditional key that needs to be inserted into the lock and turned. Electronic keys in the form of credit cards (often used in hotels) are known. But like this, it is also necessary to carry the key with you and there is a risk of loss. Besides, the door needs to be opened by hand after being unlocked by pressing the door latch or turning the door knob, and then also requires the pushing force of the door driver to push the door open. Many types of automatically opening and closing doors are already known. [0003] There are many door access control systems and automatic doors that can be operated without a key but still require physical contact, such as using a fingerprint sensor. Thi...

Problems solved by technology

However, this iris recognition method has obvious disadvantages: under some unfavorable shooting conditions for the eyes, for example, people with glasses or people with Asian-style narrow eyelids, even those whose irises have been recorded, may not be recognized by the system

This is tedious and tiring for the user as the eyes are kept still and cannot blink during this time

Scanning can dazzle the user, which can be uncomfortable or even painful
