The invention relates to a door system (1). The door system (1) comprises at least one motor door drive (2), which has a drive controller (4), and a system (3) for securing an escape route, comprising an electrically actuated door lock (10) and an escape route controller (9) which actuates the door lock (10), wherein the drive controller (4) and the escape route controller (9) are connected together via a communication connection (14), in particular via a first communication bus, and the door system (1) is designed to carry out a coordinated control of the door drive (4) and the door lock (10).

Description

Door system with a door drive and escape route security, which are connected to one another via a communication link for a coordinated control sequence actuating the door lock, according to the type defined in claim 1.

Door systems can include different components in order to reliably cover different types of applications. For example, it is known to design door systems both with a motorized door drive and with an escape route security system. Escape doors or even panic doors can be provided accordingly, with additional functions sometimes being required, for example for fire protection.

The motorized door drive comprises a drive motor and a drive controller in order to open and/or close an associated door. For this purpose, the motorized door drive can additionally comprise one or more sensors in order to monitor an area around the door in order to control the drive motor in order to open the door when a person approaches. The same applies to closing the door when the person moves away again.

The door system also includes escape route security, which is used in particular to provide escape routes. Escape route doors must always be able to be opened, for example to ensure that a building can be evacuated. At the same time, to prevent unauthorized intrusion, the escape route doors typically include an electrically operated door lock as access protection, which must be unlocked to ensure exit from the building. As fire doors can Escape route doors close automatically in the event of a fire, for example, whereby the function as an escape route door must be ensured, ie it must be possible to open the escape route door even in the event of a fire. In practice, door drives and escape route security systems are often installed by different trades. This can result in reconciliation errors. In addition, with door systems according to the state of the art, operating states must be set manually both on the door drive and on the escape route security. A faulty manual setting can cause reconciliation problems here as well.

It is therefore an object of the present invention to at least partially eliminate at least one disadvantage described above. In particular, it is the object of the present invention to specify a door system of the type described above that, in particular, ensures efficient and smooth installation and/or reliable operation of all components. In particular, in a door system with a

Drive control and an escape route security an efficiency and / or safety gain can be achieved during installation and operation.

The above object is achieved by a door system with the features of claim 1. Further features and details of the invention result from the subclaims, the description and the drawings. The task is solved in particular by a door system, whereby the

Door system comprises at least one motorized door drive with a drive controller. In addition, the door system according to the invention includes an escape route security device with an electrically operated door lock and with an escape route control, which actuates the door lock.

The door system according to the invention is characterized in that the drive control and the escape route control via a communication link, in particular via a first Communication bus, are connected to each other, and the door system is designed to perform a coordinated process of controlling the door drive and the door lock. The door system according to the invention thus provides a possibility of communication between the drive controller and the escape route controller via the communication link, so that a coordinated sequence of the drive controller and the escape route controller can be carried out by exchanging messages between the drive controller and the escape route controller, for example to enable the operation of Coordinate the door drive and door lock and prevent errors from occurring. Different types of messages can be exchanged via the communication link, for example in order to configure the other controller in each case, or to synchronize different activities with one another. The messages can contain information relating to the controller that is sending the message, or instructions to the controller that is receiving the message. For example, the escape route control can inform the drive control that the escape route control has been triggered or communicate its own configuration to the drive control. Alternatively, the escape route controller can request the drive controller to perform a specific configuration of its drive controller or to open or close the door. The same applies based on the drive control. It has been found that the communication link can achieve a high degree of freedom in order to coordinate the controls of components belonging to the escape route security or the motorized door drive, for example the door lock, carried out by the escape route security or the motorized door drive. As a result, in particular complex control processes for the door system can also be easily implemented. This applies in particular if the door system includes, for example, several motorized door drives that act as a door system be controlled together, for example in the case of double-leaf doors or a lock formed by several doors.

The control of the door drive and the door lock to perform a coordinated operation can be performed as a distributed control in which the drive control and the escape route control jointly perform the coordinated operation. For this purpose, for example, messages for synchronization between the drive control and the escape route control can be exchanged. In the door system, one of the controllers preferably acts as a higher-level controller, which carries out the coordinated sequence of the control of the door drive and the door lock, i.e. the drive controller or the escape route controller is responsible for the coordinated sequence of the control. As a further alternative, a control unit can be provided which is connected to the motorized door drive and the escape route security via the communication link, in particular to the drive controller and the escape route control, in order to carry out the coordinated sequence of the control of the door drive and the door lock and thus provide the higher-level controller. The motorized door drive includes the drive control to control a drive motor. The drive motor drives the door to open, close and/or hold. The drive control can, for example, carry out a 4-quadrant control of the drive motor. In addition, for example, an automatic door closer can be provided in order to close the door again after it has been opened or stopped. This ensures that the door can be closed again even in the event of a power failure, which can be an important feature for a fire door, for example. The electronic drive control preferably includes a processor and a memory.

In addition, the motorized door drive can include other components. The other components of the motorized door drive can include sensors, for example, in particular sensors to an approximation of detecting people on one side or both sides of the door and/or a person blocking a doorway of the door. As a result, the drive controller can control the drive motor to open, hold and/or close the door. Alternatively or additionally, the other components of the motorized door drive can include, for example, a program switch for setting an operating mode of the motorized door drive. Details are given below regarding various possible modes of operation. The other components of the motorized door drive are in communication with the drive controller in order to transmit signals from the other components of the motorized door drive to the drive controller and control signals from the drive controller to the other components of the motorized door drive. For this purpose, the other components of the motorized door drive can each be connected to the drive controller in the manner of a point-to-point connection. The point-to-point connection can be designed as an analog or digital connection, so that signals are transmitted via analog signal levels, digital signal levels or as messages. Alternatively or additionally, the motorized door drive can include a data bus, via which the other components of the motorized door drive and the drive controller communicate. B. executed separately to the communication link. Alternatively or additionally, the other components of the motorized door drive and the drive controller can communicate with one another via the communication connection, in particular via the first communication bus. Each of the other components of the motorized door drive can be connected individually to the drive controller, ie each of the other components can be connected to the drive controller independently of other components via the point-to-point connection, the data bus or the communication link.

Escape route security includes the escape route control to control the door locking. The electronic escape route control includes preferably a processor and memory. The door lock keeps doors securely closed and unlocks them immediately after activation, for example via an emergency button for emergency unlocking or with authorized release, e.g. via key switch, keyboard for entering an access code, biometric input or wireless authentication via a corresponding reader. In the event of a power failure due to an interruption in the electrical energy supply, the door lock automatically releases the door as an escape door. In this case, the electrically actuated door lock causes a lock to be released automatically, so that the door can be opened reliably if the electrical power supply is interrupted. The electrically actuated door lock can be designed as an electromagnetic or as an electromechanical door lock. The electrically operated door lock can be designed for external mounting on the door and/or frame, which means that it can be easily attached to existing doors, for example. In order to provide an optically particularly attractive system, the electrically operated door lock can also be designed for concealed installation in the door or inside the frame. In this case, the electrically actuated door lock is designed, for example, as a door opener, similar to a door opener or in the manner of a mortise lock for inclusion in a door leaf. Alternatively, the door lock can be integrated into a panic bar, for example.

In addition, the escape route security can include other components. The other components of the escape route security are in communication with the escape route control, in particular via the communication link, to transmit signals from the other components of the escape route security to the escape route control and control signals from the escape route control to the other components of the escape route security. For this purpose, the other components of the escape route security can each be connected to the escape route control in the manner of a point-to-point connection. The point-to-point connection can be designed as an analog or digital connection, so that signals can be transmitted via analog signal levels, digital signal levels or as messages are transmitted. Alternatively or additionally, the escape route security can include a data bus, via which the other components of the escape route security and the escape route control communicate. The data bus is designed separately from the communication connection. Alternatively or additionally, the other components of the escape route security and the escape route control can communicate with one another via the communication link. Each of the other components of the escape route security can be individually connected to the escape route control, ie each of the other components can be connected to the escape route control independently of other components via the point-to-point connection, the data bus or the communication link.

The other components of the escape route security can include an emergency button, an authorization checking device, in particular a key switch or a keyboard for entering an access code, and/or hazard sensors, in particular smoke or fire sensors.

An actuating element, for example a panic bar or an emergency button, enables an alarm condition to be activated in which, for example, the lock is released and the door is released for opening. This can optionally include automatic opening of the door via the motorized door drive, i.e. corresponding control of the drive motor by the drive control in order to keep the escape door open. After the alarm condition has been resolved, the door can be locked again.

The door system may include a motorized lock. The motorized lock can actuate a bolt and/or a latch of the escape door in order to allow the escape door to be opened or to prevent it from being accessed from an access side of the door. The motorized lock is preferably an anti-panic lock that can always be unlocked from a panic side of the door. In addition to the door lock, the motorized lock can thus cause an additional locking of the door. The motor lock preferably communicates with the drive controller and/or the escape route control and/or with the control device via the first communication bus.

The motor lock can be viewed in particular as a further component of the door drive.

The door system can include a reading device for recording an authorization, also referred to below as a credential. The credential can e.g. B. include an authorization code and / or a time window for an allowed access. The reading device can be designed as a reading device for the credential, which is stored, for example, on an authorization card or in an authorization chip with a memory element. Alternatively, the credential can be stored in any storage element of a mobile terminal device, for example a mobile phone or wearable, and transmitted wirelessly to the reading device. In this context, near-field communication technologies such as RF-ID, NFC or others are widespread, but also transmissions with Bluetooth, W-LAN or others. The reading device is preferably designed to cover only a small range, so that the memory element is not read out unintentionally if, for example, a person just walks past the door system.

Alternatively or additionally, the reading device can be designed as a device for capturing biometric data of an access person, in particular as a reading device for fingerprints or for iris detection, as an electronic keypad for entering an access code, or in some other way.

The program switch for setting the operating mode of the motorized door drive can preferably be coupled to the reading device for detecting the authorization in order to set the operating mode of the motorized door drive only if there is a corresponding authorization. Alternatively, authorization can be verified directly using the program switch. Different authorizations can be assigned in order to For example, to allow operating modes only depending on the respective authorization.

The aforementioned components can thus be designed as sensors and/or actuators that provide information for carrying out the control or are controlled by the respective control. The actuators can be designed, for example, as electromechanically or electromagnetically actuable actuators. In principle, the communication connection can be any connection for the transmission of digital data, the digital data comprising the messages already mentioned. In principle, any protocols can be used, which can be implemented both by software and by hardware. The communication connection can be designed for unidirectional communication, in which only the motorized door drive or the escape route security system sends messages, or for bidirectional communication, in which both the motorized door drive and the escape route security system can send messages at the same time. A particularly simple implementation of the communication link can be realized, for example, in the manner of a serial interface (RS232) or a parallel interface.

The communication link can be wired or wireless. Various wireless transmission standards can be used in a wireless communication connection, for example Bluetooth, in particular Bluetooth Low Energy (BLE), W-LAN, DECT or others. A wired communication connection can be implemented, for example, via electrical cables or also via optical cables. The communication connection is preferably implemented via the first communication bus. The first communication bus can also be wired or wireless in accordance with the above statements. In principle, the first communication bus can be any Use transfer protocols. Frequently used transmission protocols are, for example, CAN, Flexray, LIN, DCW, Ethernet, LON or LAN. The first communication bus can be implemented, for example, as a field bus or also based on an IP-based transmission protocol that is customary in the IT sector. The use of the first communication bus as a communication connection has the advantage that standardized components can be used easily, which can be provided easily and flexibly. This also facilitates the installation of the door system.

It can be ensured in different ways that all participants can use the first communication bus in the required manner. For example, bit-by-bit arbitration can be carried out, with each participant having a prioritization/identification, and in the case of simultaneous transmission, that participant which has the highest prioritization may use the first communication bus. Such methods are known, for example, under the term CSMA/CR, in order to immediately resolve possible collisions when accessing the first communication bus. Alternatively, equal access to the first communication bus is also possible, for example in the manner of collision detection (CSMA/CD). As a further alternative, a participant on the first communication bus can act as a master, which allocates resources on the first communication bus to the other participants as so-called slaves, with the resources being at least partially permanently assigned to the slaves, for example in the form of time slots (TDMA).

The implementation of the control of the door drive and the door locking with a coordinated sequence can include, for example, a timed sequence of the control of the door drive and the door locking, which takes place based on messages from the drive control and/or the escape route control. Alternatively or additionally, the control of the door drive and the door lock can include a coordinated sequence that includes a coordinated configuration of the drive control and the escape route control takes place, which causes a control of the door drive and the door lock with a coordinated process.

The coordinated operation of the control of the door drive and the door lock relates in particular to a coordinated control of the drive control for operating the drive motor for opening/closing/holding the door and for operating the door lock. It can thereby be ensured that, for example, before the door is opened with the drive motor, the door is not locked or that the door is not locked again until the drive motor has moved the door into its closed position. In particular, false alarms can be prevented which occur due to an unlocking time and/or a monitoring time of the door locking elapsing, for example if the door is only closed by the door drive after the unlocking time or the monitoring time has elapsed.

If the door system includes a motor lock, the coordinated sequence preferably includes the activation of the motor lock, so that the motor lock behaves in a coordinated manner with the door drive and with the door lock. When opening or closing the door via the drive motor, it is important that the motor lock is actuated at the right time to ensure that the door system functions correctly. The motor lock is activated in addition to the activation of the door lock. The motor lock can be controlled independently of the door lock control.

For example, the drive control is used to control the motor lock in order to unlock the motor lock. To do this, the drive control sends a command to the motor lock. The command is sent, for example, via the communication connection, in particular via the first communication bus. It may be that the motor lock reports to the drive control that the motor lock is unlocked so that the drive control then activates the motor to open the door. In addition, the door control can include the control unit, which is connected to the motorized door drive and the escape route security system via the communication link. The control unit is a data processing device. Accordingly, the control unit includes a processor and a memory in which a program for execution in the control unit is stored. The controller may have an operating system, for example based on Linux or others, the program being executed using the operating system. Alternatively, the program can be executed directly by the control device without an operating system.

Provision can be made for the control unit to carry out a coordinated process for controlling the door drive and the door locking. In this case, the control unit has a corresponding program that can control the motorized door drive and the escape route security to carry out a coordinated process. Preferably, the motorized door drive and the escape route security each form functional units that are controlled by the control unit, i.e. the control unit controls the drive control of the motorized door drive and the escape route control of the escape route security, which in turn controls corresponding components of the motorized door drive and the escape route security.

The control unit can be designed to receive messages from the drive controller and the escape route controller and forward them to the escape route controller or the drive controller.

Furthermore, the door system can include a plurality of motorized door drives, for example for two door leaves of a double-leaf door or for a lock formed by several doors. The door system, in particular the control unit, can carry out a coordinated sequence of control of the door drives and the door lock(s) via the communication link. For example, in a lock, the door drives can be delayed be controlled, or the door locks of several doors are unlocked at the same time.

According to an advantageous development of the invention, it can be provided that the escape route control is designed to receive a command and/or information from the drive controller or the control unit of the door system in order to unlock and/or lock the door lock, and the escape route control is designed , based on the received command or information to control the door lock to unlock or lock the door lock. This function of the escape route control can be stored in the escape route control, for example in firmware, which is stored as unchangeable programming in the escape route control. The command and/or the information is sent as a message to the escape route control and is received and evaluated by it. The door lock can be controlled by the escape route control in various ways.

The message with the command and/or the information to the escape route control preferably contains further parameters for the activation of the door lock, for example a relative or absolute time specification for the activation, a duration of the activation, or others. In addition, the escape route control can send information about the status of the escape route system, for example a current locking status of the

door lock or a change in lock status.

In particular, the escape route control includes a timer to record the time of the activation or the duration of the activation. For example, the timer can be used to determine an unlocking time for locking the door. The unlock time specifies how long the door lock should remain unlocked. At the beginning of the unlocking time, the escape route control activates the door lock for unlocking. At the end of the unlocking time controls the

Escape route control activates the door lock for locking. Additionally or alternatively, the control unit can include a timer. The controller may use the timer to determine the unlock time. It may be that the control unit activates the door lock for unlocking at the beginning of the unlocking time and/or the control unit activates the door lock for locking at the end of the unlocking time. Alternatively, the control device can cause the escape route control at the beginning of the unlocking time to activate the door lock for unlocking and/or at the end of the unlocking time to activate the door lock.

It can be provided that the door lock is connected to the first communication bus. The door lock is preferably controlled by the escape route control and/or the control device in that the escape route control and/or the control device sends a message via the communication bus.

It can preferably be provided that both the control device and the escape route control include a timer. In this case, it may be that the control unit controls processes that are not safety-related, in particular at least one process in which the door lock is to be unlocked on the basis of an authentication. The escape route control controls safety-related processes, in particular at least the process that follows after the actuation of a triggering element, in particular an emergency button, and/or in the event of a danger signal from a danger detector for unlocking the door lock. The control device preferably does not take part in the control of a safety-related sequence.

According to an advantageous development of the invention, it can be provided that the door system has at least two operating modes, including an automatic mode and a manual mode.

In the automatic mode, the door drive opens when a person approaches on one side of the door and/or on both sides of the door, which is detected by a sensor the door motorized. In the manual mode, the door drive fails to open the door by motor when a person approaches on one side of the door and/or on both sides of the door, which can be detected by sensors. The door system can be designed to automatically adapt the behavior of the door lock to the set operating mode by setting the operating mode for the door drive, and in particular the operating mode can be set using a program switch. The program switch is preferably part of the motorized door drive. Alternatively, the operating mode can be set centrally via the control unit.

The automatic mode of operation can include the door drive opening the door by motor when a person approaches and possibly then keeping the door open and actively closing the door after the person has moved away. In addition, in automatic mode, a distinction can be made between an operation for full door opening or for partial or partial door opening, either by actuating an input or reading device of the door system or by default in the automatic mode operating mode. For example, a "night operation" or an operation "partially open" are known. In the case of double-leaf doors, for example, a distinction can also be made between opening only one door leaf or opening both leaves. It may be that in automatic mode the door is only opened automatically when a person approaches the door from one side, while the door is not automatically opened when the person approaches from the other side of the door. The term “automatic operation” thus preferably includes a number of operating modes in which the door opens partially or completely or when a person is detected on one side of the door or on both sides of the door. The operating modes "complete opening with person detection on both sides", "partial opening", "opening (complete or partial) with only one-sided person detection" can preferably be set separately on the program switch and/or communicated to the control unit. Correspondingly, communication between an escape route safeguard and a plurality of motorized door drives, each with a drive controller, can be carried out via the communication link in order to carry out a coordinated sequence of the controller and to open the door fully. The same applies to a door system with multiple doors and corresponding door drives that form a door lock.

In manual mode, the motorized door drive can only open the door after authentication, e.g. B. using a key, credential, PIN code or biometric input, so that the door lock is usually locked and unlocked only before opening the door. For example, the motorized door drive or the control unit in manual mode can send a message to the escape route security before each door opening, in order to unlock the door lock while the door is being opened by the drive control.

According to an advantageous development of the invention, it can be provided that in an operating mode automatic mode, in which the door drive opens the door by motor when a person approaches on one side of the door and/or on both sides of the door, which is detected by sensors, the door lock is automatically unlocked , and preferably wherein the door latch remains unlocked until the operational mode is terminated. In particular, the setting of the operating mode causes automatic operation, i. H. without additional action of a user, the door lock unlocks. For this purpose, the drive control in particular sends a message, directly or indirectly via the control device, to the escape route control and/or the door lock. In particular, the message can include the information that automatic mode has been set and/or a command to unlock the door lock.

The escape route security is configured so that the door is unlocked in the automatic mode, ie the door lock releases the door permanently. After the door lock has been set in accordance with the automatic mode of operation, the escape route control can send a corresponding confirmation via the communication link. In accordance with the automatic mode of operation, a control can also be carried out as to whether all doors should be unlocked if there are several doors, for example a lock. When the automatic mode of operation is set, the door is unlocked via the door lock, preferably immediately after the escape route control has received a corresponding command and/or information. The same can apply to locking the door when another operating mode, for example manual mode, is set, in which the door lock locks the door. After the door has been locked after the end of the automatic mode of operation, corresponding information is preferably sent by the escape route control.

The sensory detection of the approach of the person can be done with one or more sensors that are attached to one or both sides of the door. This can involve motion sensors known per se or also other sensors. Preferably, at least one sensor is mounted on each side of the door to sense the approach of a person on each side of the door. The sensors are preferably part of the motorized door drive.

According to an advantageous development of the invention, it can be provided that in a manual mode of operation, in which a sensory detectable approach of a person on one side of the door and/or on both sides of the door, the door drive refrains from opening the door by motor, automatically the door lock is locked and/or a permanent unlocking of the door lock is cancelled. In particular, the setting of the manual operation mode causes the door lock to lock automatically, ie without any additional action by a user. For this purpose, the drive control in particular sends a message, directly via the control unit or directly, to the escape route control and/or the door lock. In particular, the message can include the information that manual operation has been set and/or a command to lock the door lock. The escape route security is thus configured via a corresponding message from the drive control or the control unit that the door is locked in manual mode, ie the door lock locks the door permanently. After setting the door lock in accordance with the manual mode of operation, the escape route control can send a corresponding confirmation via the communication link. In

In accordance with the manual operation mode, a control can also be carried out as to whether all doors should be locked if there are several doors. The door is preferably locked via the door lock immediately after the escape route control has received a corresponding command and/or information.

The same can apply to unlocking after the end of the manual mode of operation. After the door has been unlocked after the end of the manual mode of operation, corresponding information is preferably sent by the escape route control.

In the operating modes mentioned, an optional motorized lock can be installed in

According to the door lock are controlled so that it is ensured that the door can be opened according to the control for the respective operating mode or not. The motorized lock is preferably locked when the fire protection door is closed. A parameter that can preferably be stored in the door system according to the invention is whether the motor lock remains permanently unlocked during automatic operation, or whether the motor lock must always be unlocked again each time the door is opened during automatic operation.

According to an advantageous development of the invention, it can be provided that the door system includes an authentication device. The authentication device is used to check an authorization for example for access to an area behind the door or to set an operating mode of the motorized door drive. Corresponding authentication devices include e.g. B. a reader for recording the authorization, also referred to below as a credential. Alternatively or additionally, the reader can be designed as a device for capturing biometric data of an access person, in particular as a reader for fingerprints or for capturing irises, as an electronic keypad for entering an access code, or otherwise. The authentication device can, for example, compare biometric data with stored biometric data and thus determine whether there is authorization to open the door or to set the operating mode. The authentication device can determine an access authorization using an authorization code and/or time window of the credential. The authentication device is preferably assigned to the control unit, in particular when this is directly connected to the reader. For example, if the escape route security system includes a keyboard for entering an access code, this can also be viewed as a reader. An authentication device can additionally or alternatively be designed as a key switch, in particular as a key switch for securing the escape route, or as a lock cylinder.

According to an advantageous development of the invention, it can be provided that the door system includes an authentication device, the door being openable after authentication at the authentication device, after authentication a motor of the door drive is controlled to open the door.

The hold-open time over which the door drive keeps the door open is preferably automatically adapted to the unlocking time for which the door lock is unlocked. In particular, the hold-open time is less than or equal to

Unlocking trained. A release and an opening of the door thus takes place depending on a successful authentication, whereby outgoing from the successful authentication, a coordinated process of controlling the drive control of the motorized door drive or the escape route security with the door lock is carried out. For this purpose, a corresponding message is sent to the escape route security and/or the motorized door drive after authentication. It is important that the hold-open time, during which the drive control keeps the door open, is automatically adjusted to the unlocking time, during which the door lock is unlocked, in order to avoid disruptions in operation. For example, it is advantageous for the door lock to unlock the door before the door is opened and reliably lock the door again after the door is closed. This can be ensured by the hold-open time being less than or equal to the unlocking time.

A coordinated sequence particularly preferably also takes place during the control, in that, for example, messages are sent via the communication connection in order to avoid disruptions in operation. The message can include the hold-open time and/or the unlocking time. The drive controller and the escape route controller preferably communicate via the hold-open time and/or the unlocking time.

Alternatively, the escape route control and/or the control unit can use the timer to determine the hold-open time. At the beginning of the hold-open time, the escape route control and/or the control unit can send information or a command, based on which the drive control opens the door. At the end of the hold-open time, the escape route control and/or the control unit can send information or a command on the basis of which the drive control closes the door. In a further alternative, the drive control includes a timer. At the beginning of the unlocking time, the drive control sends information or a command, based on which the door lock is to be unlocked. At the end of the unlocking time, the drive control sends information or a command based on which the door lock is to be locked. The drive control can send such information to the control device, to the escape route control and/or to the door lock. A coordinated process of control through an exchange of messages can be carried out particularly reliably if, for example, individual steps are coordinated via the messages. Different operating modes can also be taken into account as a result, since, for example, in the case of a double-leaf door, only one door leaf can be opened more quickly than both door leaves can be opened. The same can apply in the case of a partial door opening if a door with the motorized door drive is only partially opened, as can occur during night-time operation.

According to an advantageous development of the invention, it can be provided that the door system comprises an authentication device, the door being able to be opened after authentication on the authentication device, a motor of the door drive being actuated to open the door after authentication, the hold-open time over which the door drive keeps the door open, is adapted to a monitoring time before the escape route security device issues an alarm, in particular the hold-open time being less than or equal to the monitoring time. Depending on a successful authentication, the door is thus released and opened, with the motorized door drive and the escape route security system carrying out a coordinated sequence of control of the door drive and the door locking system based on the successful authentication. An error can occur, for example, if the monitoring time has expired and the release of the door is terminated, but the door system determines that the door is still open and the hold-open time has not yet expired. The monitoring time is preferably measured in the escape route control after the door lock has been unlocked. The escape route control preferably detects whether the door is still open, for example with a door-open sensor.

A corresponding control therefore takes place, for example the escape route control indicating a start and/or the length of the monitoring time the drive control reports. Thus, a coordinated process of control can be performed by messages being sent over the communication link. The message can include the hold-open time and/or the monitoring time. The drive controller and the escape route controller preferably communicate via the hold-open time and/or the monitoring time. A coordinated sequence of the control by exchanging messages can be carried out particularly reliably if, for example, individual steps are coordinated via the messages and the end of the monitoring time while the door is being opened by the drive controller does not trigger an alarm.

Provision is preferably made for the escape route control to send a message to the drive control about the unlocking time and/or the monitoring time. Alternatively, the escape route control can send a message to the control unit about the unlocking time and/or the monitoring time. The control unit can in turn send a message to the drive control about the unlocking time and/or the monitoring time. The drive control can algorithmically determine the hold-open time from the received monitoring time and/or unlocking time, e.g. B. equate or reduce. Additionally or alternatively, the escape route control and / or the control unit, the hold-open time algorithmically based on the

Determine the unlocking time and/or the monitoring time and send it to the drive control. Alternatively, the hold-open time or the monitoring time can be set or configured between the drive controller and the escape route control via the communication link, by transferring them to the other controller, so that the hold-open time and the monitoring time can be adapted to one another. This eliminates false alarms that can occur when exceeding the

monitoring time the door is still open is avoided. Depending on the duration of the exceedance, a pre-alarm can be triggered as the first alarm level and a main alarm as the second alarm level. According to an advantageous development of the invention, it can be provided that the door system is designed to carry out a configuration that is carried out in particular when the door system is installed, the configuration of the hold-open time and/or the unlocking time and/or the monitoring time and/or an algorithm for a ratio of the hold-open time to the unlocking time and/or to the monitoring time. The configuration causes the times to be set correctly. For configuration, for example, a setting can be made using a template that contains presettings for the different times. Changes to the hold-open time and/or the unlocking time and/or the monitoring time in the template are preferably checked and rejected if the hold-open time is set to be greater than the monitoring time/unlocking time. Thus, a coordinated process of controlling the door drive and the door locking can be carried out. By appropriately configuring the ratio of the hold-open time to the unlocking time and/or to the monitoring time, a very simple control of the door drive and the door locking can be carried out with a coordinated sequence. When the hold-open time, unlocking time and/or the monitoring time is configured via the control unit, the control unit can cause a corresponding warning message to be output if the hold-open time is set to be greater than the unlocking time and/or the monitoring time.

According to an advantageous development of the invention, it can be provided that the door system includes a hazard sensor, in particular a smoke detector. The hazard sensor can be an individual sensor or comprise a plurality of individual sensors which are connected to an alarm control panel, with the alarm control panel transmitting the hazard signal. The hazard sensor can be assigned to the motorized door drive or the escape route security and can transmit a hazard signal to the drive controller or the escape route controller. Alternatively, the hazard sensor can be connected directly to the communication link in order to use it to send the hazard report. According to an advantageous development of the invention, it can be provided that the door system includes a hazard sensor, in particular a smoke detector, the door system being designed such that a hazard signal from the hazard sensor is received both by the drive controller and by the escape route controller. As a result, both the drive control and the escape route control can directly carry out appropriate controls, for example to close or open the door, with a coordinated sequence of control being carried out here as well. The danger signal can first of the danger sensor to the

Drive control or are transmitted to the escape route control, which then sends the danger signal accordingly to the escape route control or the drive control. Alternatively, the hazard signal can be transmitted from the hazard sensor to both the drive controller and the escape route controller at the same time. Another alternative is that

Danger signal are received and processed by the control unit. Based on the danger signal, the control unit decides how to proceed and sends a corresponding message to the drive control and the escape route control.

According to an advantageous development of the invention, it can be provided that in an operating mode automatic mode, in which a sensory detected approach of a person on one side of the door and/or on both sides of the door, the door drive opens the door by motor if the door system receives a danger signal a hazard sensor, in particular a smoke detector, at least one, preferably several, particularly preferably all, of the following measures are carried out by the door system:

• an approach that can be detected by sensors does not lead to the motorized opening of the door by the door drive, an open door is closed by the door drive,

• a motor lock of the door system is switched to the locking state, • The status of the escape route security system is set to Danger, in particular "Smoke alarm", which means that the door lock remains unlocked.

The measures are carried out, for example, depending on the function of the door as an escape door, panic door, fire protection door, access protection, or others. In particular, when carrying out several measures, it is important to ensure that the door drive and the door lock are controlled in a coordinated manner in order to ensure, for example in the event of a fire, that the door is first closed and, if necessary, locked and it is also ensured that the door is subsequently opened by a motor is prevented. Correspondingly, a coordinated execution of the control of the door drive and the door locking can also take place after the end of the danger, in particular the smoke alarm. For this purpose, after the end of the danger, an additional check can be carried out, for example by qualified personnel, especially if the door was opened during the danger. The door can then, for example, be transferred to its previous operating mode, for example back to automatic mode. According to an advantageous development of the invention, it can be provided that the escape route control communicates with the drive control and/or with a control unit via the first communication bus, with a hazard sensor, preferably a smoke detector or a smoke alarm control panel, being connected to the first communication bus. By communicating via the first communication bus, a plurality of participants, ie the controllers and also other components of the motorized door drive and the escape route security, can communicate easily in order to carry out a coordinated sequence of the control of the door drive and the door locking. Delays through an indirect forwarding of commands and / or information, for example, if a hazard message from the hazard sensor first to the

Escape route control takes place and then a corresponding message is sent from there to the drive control, are omitted. Alternatively, he can Hazard sensor first send a message via the first communication bus to the control unit, which forwards the message accordingly or sends a message to the drive control and / or the escape route control as required.

According to an advantageous development of the invention, it can be provided that a motor lock of the door system communicates with the drive controller and/or with the control unit via the first communication bus, and/or the escape route controller communicates with the door lock via the first communication bus. The above explanations with regard to the implementation of the coordinated sequence of the control of the door drive and the door locking apply in a corresponding manner. If the motor lock is connected directly to the first communication bus, the door system can be controlled flexibly. Local adjustments in the drive control for connecting the motor lock can be omitted, i.e. no adjustments to the installation (hardware) are required if the motor lock is integrated directly into the door system via the first communication bus. For example, the motor lock is automatically functionally integrated into the door system when the motor lock is connected to the first communication bus, i.e. the motor lock is recognized in the door system, in particular by the control unit, and the coordinated process of controlling the door drive and the door lock is transferred to the detected motor lock adjusted. The motor lock can be designed as a mortise lock. An electric motor can be arranged in a plug-in housing of the motor lock in order to retract a bolt and/or latch into the plug-in housing.

According to an advantageous development of the invention, it can be provided that the door system has a functional memory for functional sequences which are at least indirectly coordinated in sequence by the escape route control and the drive control, the functional sequences being stored in particular as firmware in the door system, in particular in the drive control Escape route control and / or the control unit are stored. the Functional sequences define the coordinated sequence of the control of the door drive and the door locking. It is a kind of control routine performed by the door system to perform a coordinated operation of door drive and door lock control. In the case of a larger number of motorized door drives and/or escape route safeguards that are included in the door system, it is particularly advantageous that the function memory, as part of the control unit, provides central functions for carrying out a coordinated sequence of the control of the door drive and the door locking, so that these do not must be provided redundantly in door drive(s) and/or escape route security(s). In addition, door drive(s) and/or escape route security(s) can include function memory for providing your special functions and/or for communication via the communication link. For example, the drive control includes a function memory for controlling the drive motor.

With a function memory in the control device, it is also possible to carry out a particularly simple adaptation of central function sequences, since only one device needs to be accessed. Adjustments to the central functional processes can, for example, be in the form of an update

firmware of the control unit. The functional sequences can be adapted locally, for example by temporarily establishing a data connection from an update computer to the control device, for example via Bluetooth, WLAN, USB or other wired or wireless transmission standards. Alternatively, the

The functional sequences are adapted via an update server if the control device is connected to the update server, for example as a cloud server, for example via the second communication bus as an Internet connection. As a result, updates for a large number of control units can be provided and implemented in a simple manner. The same applies to function memories of the drive control or the escape route control, which can also be supplied with updates locally. Also can such Updates, for example, take place indirectly via the control unit when the control unit is connected to the update server.

For safety reasons, a configuration of the escape route security, in particular an assignment of a door lock to an emergency button, the approval of a time delay until unlocking after pressing the emergency button, the length of the time delay, an approval of a deactivation of the emergency button, can only be approved on site. For example, the configuration can take place via wireless short-range communication with the mobile terminal device. A configuration via the update server is preferably excluded.

For example, a parameter of the escape route security, z. B. the length of a time delay, approval of a deactivation of the triggering element, approval of a time delay, can be changed during commissioning on site by sending the change from a server or from a mobile terminal and receiving it from the control unit. The parameter can e.g. B. be changed by entering into the mobile device. The control unit sends the changed parameter to the escape route control. If there are several escape route safeguards in the door system, the control device can preferably send the changed parameter selectively to the at least one escape route control for which the parameter is provided. Provision is preferably made for that escape route control which receives the parameter from the control device to emit a visual and/or acoustic signal that a parameter has been received. The installer preferably confirms, e.g. B. on the mobile device and / or on the escape route control that the correct escape route control has given to the acoustic and / or visual signal. After confirmation, the parameters are preferably saved for use in the escape route control.

Additionally or alternatively, before the parameter is sent, the control device prompts that escape route control which received the parameter intended, emits a visual and/or acoustic signal. The installer preferably confirms, e.g. B. on the mobile device and / or on the escape route control that the correct escape route control has given to the acoustic and / or visual signal. After confirmation, the parameters are preferably sent to the escape route control.

This can ensure that the correct escape route control has received the changed parameter. The installer must therefore be on site to change the parameter of the escape route security. The change is thus carried out in a particularly reliable manner. In order to carry out the visual and/or acoustic signal, it is preferably provided that the escape route component comprises a display element. The display element is preferably used by the escape route control during operation of the door system in order to emit a visual and/or acoustic signal. For example, the display element can be designed to display an alarm condition after actuation of the triggering element.

It may be envisaged that the on-site installer performs an action on the escape route control or on a component hardwired to or integral with the escape route control to confirm and/or establish that the escape route control has received or has received the changed parameter target. For example, the installer can actuate the release element, in particular the emergency button, or a key switch. This ensures that the safety-relevant configuration of the escape route system is only carried out on site.

The second communication bus preferably provides a connection to the Internet or the cloud, so that the control device can be connected to a corresponding server. The connection is preferably secured and the second communication bus can be connected to the Internet, for example via a secure communication device, for example a firewall. Alternatively, the second communication bus as an internal network (intranet), for example, a building with the door system be executed, wherein the internal network can be connected to the Internet.

According to an advantageous development of the invention, it can be provided that the door system includes an authentication device, with the control device being designed as an authentication device. The control unit thus receives an authorization, for example via a reader, and can compare this authorization with authorizations stored in the control unit and thus check the authentication. Alternatively, the control unit is connected to an authorization server, for example via the second communication bus, which can check the authentication centrally and transmits the result of the check to the control unit. This is particularly advantageous in larger installations with a number of door systems, in order to be able to easily manage authorizations.

According to an advantageous development of the invention, it can be provided that the door system has a control unit which is connected to the first communication bus, the control unit being able to be connected to a second communication bus and/or the drive control and the escape route control communicating with one another at least partially via the control unit. When the control unit is connected to a server, in particular via the Internet, various functions can be implemented with the control unit as part of remote monitoring, for example configuration, monitoring, support, maintenance, updates or the like. An initial set-up of the control unit can also be carried out easily if, for example, all the components of the motorized door drive and the escape route protection in the control unit are known.

If the drive control and the escape route control communicate with one another via the control unit, functional sequences for carrying out a coordinated sequence of the control of the door drive and the door locking can be easily implemented centrally in the control unit. This means that there is no adjustment of these functional processes within the drive control or the Escape route control required, so that no additional functionalities have to be implemented there. This makes it possible to control the drive and the escape route with a simple and inexpensive

Provide implementation and provide the entire required functionality of the door system to perform a coordinated process of controlling the door drive and the door lock in the control unit. It is only necessary to provide the control unit with a corresponding functionality, while the drive control and escape route control are designed only to provide their specific functions and/or to communicate via the communication link. For example, the drive control is designed to control the drive motor.

According to an advantageous development of the invention, it can be provided that the door system comprises an authentication device, with the authentication device being designed to receive a credential for authentication, with the door system being designed to automatically carry out at least one of the following operating functions on the basis of the credential:

• Changeover of an operating mode from automatic mode to manual mode on one or more doors,

• Switching an operating mode from manual to automatic mode on one or more doors,

• cancellation of a permanent unlocking of the door lock and/or a motor lock on one or more doors,

• Unlocking the door lock and/or a motor lock on one or more doors,

• Motorized opening of the door by means of the door drive on one or more doors, and

• Motorized closing of the door using the door drive on one or more doors.

The authentication device receives the credential. The credential thus includes a parameter for authentication, for example at the same time with a specific control of the motorized door drive and / or the escape route security.

It may be that when a person authenticates himself with a predetermined credential, the operating mode of the door system is automatically changed. Thus, with the authentication, the operating mode can be set from manual to automatic or vice versa. Examples are the security guard leaving the building in the evening, or a business owner entering his shop in the morning. It is therefore not necessary for the person to actuate the program switch. Rather, the program switch is switched over in particular at the same time as the door is opened. The authentication is preferably used to change the operating mode on several doors. For example, a separate program switch for setting an operating mode of the motorized door drive can be omitted.

It may be that the permanent unlocking on the door lock and/or the motor lock is canceled with the authentication. For example, this can go hand in hand with the changeover to manual operation. It is possible that the operating modes will be changed and/or the permanent unlocking will be canceled on one or more doors. The multiple doors can be locked by motorized locks and/or door locks of the same door system and/or can be opened by door drives of the same door system.

The credential can indicate whether a door is not only approved for opening, i.e. can be opened, but whether the door is also opened if the authentication is successful. Thus, for an authorized user, the door is opened by a motor, while for another authorized user, the door is not opened by a motor, but the door lock is unlocked. The same can apply to a holding period or a closing of the door. When the operating mode is changed, for example, the door may not be opened if, for example, a corresponding change is carried out on the door system by a security service after office hours. The credential can specify whether one door leaf or both door leaves are opened on a double-leaf door. For example, in the case of a wheelchair user, both wings can be opened automatically in the case of double-leaf doors, while only one wing is opened in the case of other credentials. The same can apply, for example, in the hospital for staff who typically transport beds and are therefore also dependent on opening both wings by default. It is also conceivable to use a credential to override the conditions under which the doors of a lock open. So it can e.g. B. allows a firefighter to open both lock doors at the same time.

escape route control.

In the following figures, the same reference numbers are used for the same technical features of different exemplary embodiments.

FIG. 1 shows a schematic representation of a door system 1 according to a first preferred embodiment of the invention. The door system 1 includes a motorized door drive 2 and an escape route safeguard 3, as can be seen in FIG.

The motorized door drive 2 includes a drive controller 4 to control a drive motor of the door. The drive motor drives the door to open, close and/or hold. The drive control 4 is designed here as a 4-quadrant control. The electronic drive control 4 preferably includes a processor and a memory.

In this exemplary embodiment, the motorized door drive 2 also includes a sensor unit 5 with two sensors 6 in order to prevent people from approaching both sides of the door. The sensors 6 are in the form of movement sensors, with one sensor 6 being fitted on each side of the door in order to detect the approach of a person to a corresponding side of the door. In addition, sensors (not shown) can be provided in order to detect the presence of a person in a travel path of the door.

The motorized door drive 2 also includes a program switch 7 for setting an operating mode of the motorized door drive 2. The motorized door drive 2 also includes a motorized lock 8 to actuate a bolt and/or a latch of the door. The escape route security 3 includes an escape route control 9 and an electrically operated door lock 10.

The electronic escape route control 9 preferably includes a processor and a memory. The escape route control 9 is designed to actuate the door lock 10 . The door lock 10 keeps the associated door closed and unlocks it after activation In the event of a power failure due to an interruption in the electrical energy supply, the door lock 10 automatically releases the door as an escape door. The door system 1 includes a plurality of smoke detectors 11 as hazard sensors, which are connected to a hazard alarm center 12 . In this exemplary embodiment, the smoke detectors 11 are assigned to the emergency alarm control panel 12 of the escape route security system 3 . The door system 1 of the first embodiment additionally includes a control unit 13. The control unit 13 is a data processing device and includes a processor and a memory in which a program for execution in the control unit 13 is stored. The motorized door drive 2, the escape route safeguard 3 and the control unit 13 are connected to one another via a communication connection 14, which is designed here as a first communication bus. Accordingly, both the drive control 4, the escape route control 9 and the control device 13 are connected to the first communication bus 14. In addition, the sensor unit 5, the program switch 7, the motor lock 8, the electrically operated door lock 10 and the alarm control panel 12 are connected directly to the first communication bus 14. Instead of the sensor unit 5 as Alternatively, the sensors 6 can also be individually connected to the first communication bus 13 as a unit.

The first communication bus 14 is designed here as a wired bus based on the CAN standard. All participants, i.e. the drive control 4, the escape route control 9, the control unit 13, the sensor unit 5, the program switch 7, the motor lock 8, the electrically operated door lock 10 and the alarm control panel 12, are each assigned a unique prioritization/identification, with the simultaneous sending that participant may use the first communication bus 14, which has the highest prioritization.

Different types of messages can be exchanged between all participants via the first communication bus 14, for example in order to configure the respective other controller or to synchronize different activities with one another. The messages can contain information relating to the controller that is sending the message, or instructions to the controller that is receiving the message. For example, the escape route control 9, the drive control 4 via a

Inform the escape route control 9 is triggered or inform the drive control 4 of your own configuration. Alternatively, the escape route controller 9 can request the drive controller 4 to carry out a specific configuration of its drive controller 4 or to open or close the door. The same applies in reverse, starting from the drive controller 4 . Some examples of a coordinated process of controlling the door system 1 are described below.

The sensor unit 5, the program switch 7 and the motor lock 8 are in communication with the drive controller 4 via the first communication bus 14 in order to send signals to the drive controller 4 and to receive control signals from the drive controller 4. Correspondingly, the door lock 10 and the alarm control panel 12 are connected via the first communication bus 14 in Communication with the escape route control 9. The motorized door drive 2 and the escape route safeguard 3 each form corresponding functional units.

The door system 1 has a functional memory for functional sequences which are at least indirectly coordinated in sequence by the escape route control 9 and the drive control 4 . The functional sequences are stored as firmware in the door system 1 and define the coordinated sequence of the control of the door drive 2 and the door lock 3. The functional memory is arranged in the drive control 4, the escape route control 9 and the control device 13 in order to implement control functions therein and a coordinated Process of controlling the door drive 2 and the door lock 10 to perform.

Furthermore, the control device 13 is connected to a second communication bus 15, which is designed as an Internet connection. The control unit 13 is connected to a plurality of servers 16 via the second communication bus 15 . The servers 16 can be designed as cloud servers, for example. The connection of the control unit 13 to the servers 16 is preferably secured and encrypted. The second communication bus 15 is connected to the Internet via a secure communication device, for example a firewall.

The door system 1 includes a reading device 17 for recording an authorization, also referred to below as a credential. The reader 17 is used as a reader 17 for an electronic authorization code and/or a time window for permitted access, which is stored, for example, on an authorization card or in an authorization chip with a memory element, and/or as a reader 17 for capturing biometric data an access person, in particular as a reading device 17 for a fingerprint or for iris detection. The reading device 17 is connected directly to the control unit 13 via a connection interface 18, which is designed here as an interface based on the RS485 standard. The door system 1 also includes an authentication device for checking authorizations, for example for access to an area behind the door or for setting an operating mode of the motorized door drive. The authentication device is formed here by the control unit 13 together with the reading device 17 . The authentication device compares credentials or biometric data read with the reading device 17 with stored credentials or biometric data and thus determines whether authorization is present. The comparison preferably takes place in the control unit 13. The door system 1 is designed to carry out a coordinated sequence of the control of the door drive 2 and the door lock 3, as explained in detail below. For this purpose, there is a communication between the door drive 2 and the escape route security device 3, so that the coordinated process of the drive control 4 and the escape route control 9 can be carried out by an exchange of messages.

In addition, the door system 1 has two operating modes, namely an automatic mode and a manual mode. In automatic mode, when a person approaches one side of the door and/or on both sides of the door, which is detected by sensors using the sensor unit 5, the door is opened by the motor of the door drive 2. In manual mode, the door is not opened by door drive 2.

In one embodiment, the door system 1 is designed to carry out a configuration, which is carried out in particular when the door system 1 is installed, the configuration determining the hold-open time and/or the unlocking time and/or the monitoring time and/or an algorithm for a ratio of the hold-open time to the Unlocking time and / or includes monitoring time. For configuration, for example, a setting can be made using a template that contains presettings for the different times. Various coordinated processes for controlling the door drive 2 and the door lock 10 of the door system 1 of the first embodiment are described below with additional reference to the flowcharts in FIGS.

FIG. 2 shows a flowchart for activating and deactivating an automatic mode of operation. The operating mode is with the

Program switch 7 of door drive 2 set. The program switch 7 sends a corresponding message with the operating mode, which is automatic mode here, via the first communication bus 14 to the drive controller 4, which activates the operating mode for the motorized door drive 2.

The drive controller 4 then transmits via the first

Communication bus 14 sends a message “EPS(AUTO)” to control unit 13, so that control unit 13 is informed about the set operating mode. This causes the control unit 13 to send a message “9(unlock, duration)” to the escape route control 9 via the first communication bus 14, so that the door is unlocked by the door lock 10 for the automatic mode of operation. The escape route controller 9 performs a permanent unlocking for the door by sending a message to the door lock 10 via the first communication bus 14 to unlock the door permanently. The door lock 10 confirms the unlocking with a corresponding message to the escape route control 9, which then sends a message "Status (unlocked, duration)" to the control unit 13. The control unit 13 forwards the message “Status (unlocked, duration)” to the drive control 4 .

After the door lock 10 has been unlocked, the drive controller 4 sends a command “8(unlock)” to the motor lock 8 via the first communication bus 14 in order to drive it, retract the latch and/or bolt and thus unlock the door. The motor lock 8 then sends an acknowledgment “8(unlocked)” to the drive controller 4 via the first communication bus 14. As a result, the drive controller 4 knows that the door is fully unlocked and the door can open the door immediately upon receipt of a corresponding message via the first communication bus 14 from the sensor unit 5 . The unlocking of the door lock 10 and the unlocking of the door via the motorized lock 8 can be carried out in reverse order or in parallel.

The behavior of the door lock 10 is thus automatically adapted to the set operating mode by the described setting of the operating mode automatic mode for the door drive 2 . In automatic mode, a distinction can be made between an operation for full door opening or for partial or partial door opening, either by actuating the program switch 6 or by default in the automatic mode operating mode. For example, "night operation" or "partially open" operation are known. In the case of double-leaf doors, for example, a distinction can also be made between opening only one door leaf or opening both door leaves.

A comparable transmission of messages takes place when the automatic mode of operation is issued with the program switch 7 of the door drive 2 . The program switch 7 sends a corresponding message with the operating mode to the drive controller 4 via the first communication bus 14, which switches off the automatic mode for the motorized door drive 2, so that the door goes into manual mode, for example. The drive controller 4 sends a message "EPS(OFF)" to the control unit 13 via the first communication bus 14. This causes the control unit 13 to send a message "9(lock)" to the escape route control 9 via the first communication bus 14, so that the door is locked. The escape route controller 9 locks the door by sending a message to the door lock 10 via the first communication bus 14 to lock the door. The door lock 10 confirms the locking with a corresponding message to the escape route control 9, which then sends a message "Status (locked)" to the control unit 13. The control unit 13 forwards the message "Status (locked)" to the drive controller 4 .

After locking the door via the door lock 10, the drive controller 4 sends a command "8(lock)" to the motor lock 8 via the first communication bus 14 in order to drive it, deploy the latch and/or bolt or allow mechanical deployment and thus the to lock door. The motor lock 8 then sends an acknowledgment “8(locked)” to the drive controller 4 via the first communication bus 14. As a result, the drive controller 4 knows that the door is locked. That

Locking the door lock 10 and locking the door via the motorized lock 8 can be carried out in reverse order or in parallel. Instead of the permanent unlocking of the motorized lock 8 during the

In automatic mode, the motor lock 8 can be unlocked in automatic mode if the drive controller 4 contains a corresponding message from the sensor unit 5 via the first communication bus 14 . Otherwise, the motorized lock 8 remains locked during automatic operation. Whether the motorized lock is locked or unlocked in automatic mode when the sensor unit 5 has not detected a person can preferably be stored electronically as an adjustable parameter in the door system 1 .

FIG. 3 shows a flowchart for temporarily unlocking the door. The short-term unlocking takes place, for example, based on an operation with a key switch of the escape route security 3, from the

Escape route control 9 is detected. The escape route controller 9 then sends a message to the door lock 10 via the first communication bus 14 in order to temporarily unlock the door. The door lock 10 confirms unlocking with a message to the

Escape route control 9. The door can also be unlocked via the door lock 10 at a later point in time. The escape route controller 9 then sends a message “9(unlocked, short, time in seconds)” to the control unit 13 via the first communication bus 14, so that the control unit 13 is informed about the set opening of the door. Here, the unlocking time is included in the message. The control unit 13 in turn sends a message “Night bench (time in sec)” to the drive controller 4 via the first communication bus 14. The message includes either the unlocking time or a hold-open time adapted to the unlocking time. After receiving the message, the drive controller 4 sends a command “8(unlock)” to the motor lock 8 via the first communication bus 14 in order to drive it, retract the latch and/or bolt and thus unlock the door. The motorized lock 8 then sends an acknowledgment “Status (unlocked)” to the drive controller 4 via the first communication bus 14. The drive controller 4 then opens the door for the hold-open time specified in the message “NachtBank(Zeit in sec)” or which can be calculated using the message . A confirmation “status (door open, 8 unlocked)” is sent from the drive controller 4 to the controller 13 , which forwards the message to the escape route controller 9 .

After the open time specified or calculable in the message "NachtBank(Zeit in sec)" has elapsed, the drive controller 4 sends a command "8(lock)" via the first communication bus 14 to the motorized lock 8 in order to drive it, latch and/or Extend bolt or allow mechanical extension and thus lock the door. Alternatively, in the case of a self-locking motorized lock, the message "8(lock)" can be sent immediately after the motorized door is opened. After locking has taken place, the motor lock 8 sends a confirmation “Status (locked)” to the drive controller 4 via the first communication bus 14. A confirmation “Status (door closed, 8 locked)” is sent from the drive controller 4 to the control unit 13, which forwards the message to the escape route control 9. Because the escape route controller 9 sends the monitoring time and/or the unlocking time to the control unit 13, a hold-open time adapted to the monitoring time and/or the unlocking time can be sent to the drive controller 4 to keep the door open. This avoids false alarms.

As an alternative and not shown, control unit 13 can determine the hold-open time. At the end of the hold-open time, the control unit 13 sends a message to the drive controller 4 about the end of the hold-open time.

In FIG. 3, the message “night bench” specifies in particular that the drive controller 4 must open the door only partially and/or that the “manual operation” operating mode is present. FIG. 4 shows a flowchart for operating the door after authentication via the authentication device. The authentication thus includes that a chip card with a credential is first read in with the reader 17 and compared with the stored credentials in the control unit 13 in order to check authorization to open the door.

After the authentication, the control unit 13 sends a message “9(unlock, short, time in sec)” to the escape route controller 9 via the first communication bus 14 so that the door is unlocked for the unlocking time specified in the message. The escape route controller 9 sends a message to the door lock 10 via the first communication bus 14, which unlocks the locking of the door for the specified period of time, the unlocking time. The door lock 10 confirms the unlocking with a corresponding message to the escape route control 9, which then sends a message "status (unlocked, short, time in sec)" to the control unit 13.

The control unit 13 then sends a message “Night Bank (time in sec)” to the drive controller 4 via the first communication bus 14 sends a command “8(unlock)” to the motor lock 8 upon receipt of this message in order to drive it, retract the latch and/or bolt and thus unlock the door. The motor lock 8 then sends an acknowledgment "8(unlocked)" to the drive controller 4 via the first communication bus 14. The drive controller 4 thereby knows that the door is fully unlocked and opens the door for the time indicated in the message "Night bank(time in sec)" specified hold-open time. The hold-open time and the unlocking time are adjusted in such a way that the hold-open time is shorter than the unlocking time. A confirmation “status (door open, 8 unlocked)” is also sent from the drive controller 4 to the control device 13 .

As an alternative and not shown, control unit 13 can determine the hold-open time. At the end of the hold-open time, the control unit 13 sends a message to the drive controller 4 about the end of the hold-open time. Figure 5 shows a flowchart for opening the door after manual

Unlocking via the motor lock 8. The automatic mode is deactivated.

The motorized lock 8 is unlocked manually, i.e. it is actuated with a key, whereby in particular a bolt of the motorized lock 8 is pulled back. The motor lock 8 sends a message "Status (manual unlock via PZ)" directly to the control unit 13 via the first communication bus 14. The control unit 13 then sends a message "9(unlock, short, time in sec)" via the first communication bus 14. “ to the escape route control 9. The escape route control 9 carries a

Temporary unlocking of the door lock 10 as described above by sending a message to the door lock 10 via the first communication bus 14, the door lock 10 unlocks the door and then sends a confirmation message via the first communication bus 14 to the escape route control 9. The escape route controller 9 then sends a message “9(unlocked, short, time in seconds)” to the control unit 13 via the first communication bus 14, so that the control unit 13 is informed that the door lock 10 has been unlocked. The "Time in sec" parameter specifies the Unlocking time, for the duration of which the door lock 10 is unlocked. After the unlocking time has elapsed, the escape route control 9 locks the door lock 10 and sends a “Status (locked)” message to the control unit 13.

After the motor lock 8 has been manually locked again by being actuated with a key or, in the case of a self-locking lock, the door has been closed, as a result of which in particular a bolt of the motor lock 8 has been extended, the motor lock 8 sends a message “Status ( locked)" directly to the control unit 13.

FIG. 6 shows a flowchart for opening the door in the event of a smoke alarm that was detected via the drive controller 4. The door drive 2 is in the automatic mode.

A smoke alarm is detected by the drive controller 4 in this operating mode. The drive controller 4 sends a “smoke alarm” message to the controller 13. The controller 13 in turn sends a message “9(smoke alarm)” to the escape route controller 9, which confirms receipt of this message with the message “Status (smoke alarm)”. The escape route control 9 then controls the door lock 10 for unlocking. In addition, the drive controller 4 controls the drive motor of the door in order to close the door. The door is only closed if the door was open at the time of the smoke alarm. Subsequently, messages from the sensors 5 that detect a person approaching do not lead to a motorized opening of the door by the door drive, although the door was in automatic mode before the start of the smoke alarm. After the door has been closed, the drive controller 4 sends a message “8(lock)” to the motor lock 8 in order to drive it, extend the latch and/or bolt or allow mechanical extension and thus lock the door. Alternatively, in the case of a self-locking motor lock, the message ,,8(lock) can be sent immediately after the motorized door opening. After locking, the motor lock 8 sends an acknowledgment “8(locked)” to the drive controller 4 via the first communication bus 14. As a result, the drive controller 4 knows that the door is locked. In this state, an approach of a person detected by the sensors 6 of the sensor unit 5 does not lead to the motorized opening of the door by the door drive 2.

In order to cancel the smoke alarm and return the door to a normal operating mode, for example automatic mode, the smoke alarm is acknowledged and deactivated on the drive controller 4 by an appropriate user, for example the fire brigade. The drive controller 4 then sends a message "Smoke alarm ended" to the control unit 13. The control unit 13 in turn sends a corresponding message "Smoke alarm ended" to the escape route control 9, which confirms receipt of this message with the message "Status (smoke alarm)". If the door system 1 is in automatic mode, the escape route control 9 leaves the door lock 10 unlocked, as has already been described above. In FIG. 7, a door system 1 according to the invention is shown schematically according to a second embodiment. The door system 1 of the second embodiment corresponds in essential features to the door system 1 of the first embodiment, so that the description here focuses on the differences between the two door systems 1 . In case of doubt and to the extent necessary, features that are not explicitly described correspond to those of the first embodiment.

In accordance with the door system 1 of the first embodiment, the door system 1 of the second embodiment comprises a motorized door drive 2 and an escape route safeguard 3, as can be seen from FIG. Details of the motorized door drive 2 and the escape route safeguard 3 of the second embodiment correspond to those of the first embodiment. Compared to the door system 1 of the first embodiment, the door system 1 of the second embodiment does not include a control unit 13 and no reader 17 connected thereto. The door system 1 of the second embodiment also has a

Functional memory for functional processes that are at least indirectly coordinated by the escape route control 9 and the drive control 4 in the process. The functional processes are stored as firmware in the door system 1 and define the coordinated process of controlling the door drive 2 and the door lock 3. The function memory is located in the drive controller 4 and the escape route controller 9 in order to implement control functions therein and coordinate the control process of the Door drive 2 and the door lock 10 to perform. In the door system 1 of the second embodiment are the motor

Door drive 2 and the escape route security 3 also connected via a communication link 14, which is also designed as a first communication bus. The door system 1 is designed to carry out a coordinated process of controlling the door drive 2 and the door lock 3 . Compared to the door system 1 of the first embodiment, the door system 1 of the second embodiment is controlled directly by a coordinated control sequence, which is coordinated by the drive control 4 and the escape route control 9, as explained below by way of example.

Various coordinated processes for controlling the door drive 2 and the door lock 10 with the door system 1 of the second embodiment are described below with reference to FIGS.

FIG. 8 shows a flowchart for activating and deactivating an automatic mode of operation. The operating mode is with the Program switch 7 of door drive 2 set. The program switch 7 sends a corresponding message with the operating mode, which is automatic mode here, via the first communication bus 14 to the drive controller 4, which activates the operating mode for the motorized door drive 2.

The drive controller 4 then sends a message “9(unlock, duration)” to the escape route controller 9 via the first communication bus 14 so that the door is unlocked for the automatic mode of operation. The escape route controller 9 performs a permanent unlocking of the door lock 10 by sending a message to the door lock 10 via the first communication bus 14 to unlock the locking of the door lock 10 permanently. The door lock 10 confirms the unlocking with a corresponding message to the escape route control 9, which then sends a message "Status (unlocked, duration)" to the drive control 4.

After the door lock 10 has been unlocked, the drive controller 4 sends a command “8(unlock)” to the motor lock 8 via the first communication bus 14 in order to drive it, retract the latch and/or bolt and thus unlock the door. The motor lock 8 then sends an acknowledgment “8(unlocked)” to the drive controller 4 via the first communication bus 14. The drive controller 4 thereby knows that the door is fully unlocked and can open the door each time a corresponding message is received via the first communication bus 14 from the sensor unit 5 open the door immediately. The unlocking of the door lock 10 and the unlocking of the door via the motorized lock 8 can be carried out in reverse order or in parallel.

The behavior of the door lock 10 is thus automatically adapted to the set operating mode by the described setting of the operating mode automatic mode for the door drive 2 . In automatic mode, a distinction can be made between an operation for full door opening or for partial or partial door opening, either by actuation on the program switch 6 or by default in the automatic mode. For example, "night operation" or "partially open" operation are known. In the case of double-leaf doors, for example, a distinction can also be made between opening only one door leaf or opening both door leaves.

A comparable transmission of messages takes place when the automatic mode of operation is switched off with the program switch 7 of the door drive 2 . The program switch 7 sends a corresponding message with the operating mode to the drive controller 4 via the first communication bus 14, which switches off the automatic mode for the motorized door drive 2, so that the door goes into manual mode, for example.

The drive controller 4 sends a message “9(lock)” to the escape route controller 9 via the first communication bus 14 so that the door is locked. The escape route controller 9 locks the door by sending a message to the door lock 10 via the first communication bus 14 to lock the door. The door lock 10 confirms the locking with a corresponding message to the escape route control 9, which then sends a message "Status (locked)" to the drive control 4.

After locking the door via the door lock 10, the drive controller 4 sends a command "8(lock)" to the motor lock 8 via the first communication bus 14 in order to drive it, deploy the latch and/or bolt or allow mechanical deployment and thus the to lock door. Alternatively, in the case of a self-locking motorized lock, the message "8(lock)" can be sent immediately after the motorized door is opened. After locking, the motor lock 8 sends an acknowledgment “8(locked)” to the drive controller 4 via the first communication bus 14. As a result, the drive controller 4 knows that the door is locked. Locking the door latch 10 and locking the door The motor lock 8 can be used in reverse order or in parallel.

FIG. 9 shows a flowchart for temporarily unlocking the door. The temporary unlocking takes place, for example, based on an actuation with a key switch of the escape route safeguard 3, which is detected by the escape route control 9. The escape route controller 9 then sends a message to the door lock 10 via the first communication bus 14 in order to temporarily unlock the door. The door lock 10 confirms unlocking with a message to the

Escape route control 9.

The escape route control 9 then transmits via the first

Communication bus 14 a message "Night bank (time in sec)" to the drive controller 4. The message includes the unlocking time or the hold-open time. The drive controller 4 then sends a command “8(unlock)” via the first communication bus 14 to the motorized lock 8 in order to drive it, retract the latch and/or bolt and thus unlock the door. The motor lock 8 then sends an acknowledgment “status (unlocked)” to the first communication bus 14

Drive control 4. The drive control 4 then opens the door for the hold-open time specified in the message “Night bank (time in sec)” or which can be calculated from the message. A confirmation "status (door open, 8 unlocked)" is sent from the drive control 4 to the escape route control 9 .

After the hold-open time specified in the message "AfterBank(time in sec)" has elapsed, the drive controller 4 sends a command "8(lock)" via the first communication bus 14 to the motorized lock 8 in order to drive it, latch and/or bolt to extend or allow mechanical extension and thus lock the door. Then send that

Motor lock 8 via the first communication bus 14 a confirmation "status (locked)" to the drive controller 4. There is a confirmation "Status (door closed, 8 locked)" sent from the drive controller 4 to the escape route controller 9.

Alternatively and not shown, the escape route control 9 can determine the hold-open time using a timer. At the end of the hold-open time, the

Escape route control 9 to the drive control 4 a message about the end of the hold-open time.

The above explanation of the embodiments describes the present invention exclusively in the context of examples.

It goes without saying that individual features of the embodiments can be freely combined with one another, insofar as this makes technical sense, without departing from the scope of the present invention. Reference List
