Abstract: A door system for at least one door, the door system including door components, with one of the components being designed as a control unit. The control unit and at least one other door component are connected to one another via a first communication bus. An access system with an above door system and with a computing unit are related, with an image of the door system stored in the computing unit, the door components connected to the first communication bus each having an identifier. The identifiers are stored as part of the image of the door system in the computing unit and/or with past and current operating states of the door system stored in the computing unit. An access system with at least one of the above door systems is related, with at least one door system having an authentication device configured to receive an access attribute for authentication.

Abstract: A door system for one or more doors, wherein the door system includes at least one motor door drive, and the door drive includes a motor and a drive controller for actuating the motor of the door drive. The door system includes a controller which is connected to the drive controller.

Abstract: A method for controlling at least one door system for separating an entrance side in front of the door system from an exit side behind the door system, with the door system (100) being configured with a sensor unit for detecting at least one person within a sensor detection region, and furthermore an authentication device for authenticating people is provided at least on the entrance side in front of the door system. The method includes the following steps: granting an access authorization to the person by the authentication device, detecting the position of the authenticated person by the sensor unit in the sensor detection region, continuously tracking the person in the sensor detection region by the sensor unit and activating an opening of the leaf element of the door system by the door drive when the authenticated person approaches the at least one leaf element.

Abstract: A door closer assembly includes a door closer without a powered drive for closing a door. The door closer includes an energy accumulator, wherein the energy accumulator is chargeable by manually opening the door and wherein the energy accumulator discharges for closing the door. A sensor unit is also included for detecting an angle information with regard to the opening angle of the door.
