• a locking device, for. B. a motorized lock,
• a controller, with a receiver for receiving an opening signal by radio,
• a communication unit arranged in range of the control as network server, which is integrated in a local radio network and which also has a transmitter for the transmission of an opening signal by radio to the receiver of the controller, and

Locking system means in the context of the invention, in particular a door locking system of a security-relevant door, such as an entrance door of a family house or apartment building or even a commercial or public building. Such a door locking system has at least one locking mechanism for locking and unlocking the door. In addition or as an alternative to the provided mechanical access control system (in particular keys), other identification devices (finger scanning devices, transponders, remote control keys or the like) are often provided in practice, so that the locking system can be opened by authorized persons even without mechanical keys. That's it Lock (which may for example be designed as multiple locking) motorized, so that, for example, a (separate) motor assembly may be provided with the at least one release of the lock (and possibly also a lock) is possible. The controller can be integrated in the lock or in the motor unit. Preferably, it is a separate control that can be arranged in the door leaf or in the door frame and by cable or wireless in the engine (for example, to unlock the lock) controls. The various electronic electronic keys (eg radio hand transmitters, transponders or even authorized users of a finger scanner device) may be stored in the controller.

The functionality of such a locking system is increased by the fact that a communication unit is provided as a network server as it were as an additional electronic key, which - as well as possibly other electronic keys - as "authorized access" is stored in the controller. Such a communication unit is marketed by Carl Fuhr GmbH & Co. KG under the name "SmartConnect". In this communication unit, several terminals (eg smartphones) can be registered via an intuitive app, so that is communicated via the smartphone via a wireless network (especially WLAN) with the communication unit (SmartConnect). For example, an opening command can be transmitted to the communication unit via the smartphone, in which case an opening signal is transmitted to the controller by the communication unit (by radio). The communication unit can be provided in a separate housing with power supply and mains plug. For example, it is plugged into a mains socket inside the building near the door (inside) and "taught in" in the control. Then, for example, the door can be unlocked by smartphone, whereby the smartphone can either be connected to the communication unit via WLAN or, if necessary, via the Internet and the local WLAN communicates. In this way, a plurality of users can be managed very easily, with only a single communication unit in the (conventional) control must be trained. At the same time, however, the possibility remains of unlocking the lock with conventional radio keys (eg radio hand transmitters, transponders or the like) which are taught in the control. This well-known system based on the "Fuhr-SmartConnect" has proven to be excellent in practice, but it is still capable of development. - This is where the invention starts.

Incidentally, one knows from the DE 10 2010 056 352 A1 a conventional locking system based on the transponder technology, wherein a touch sensor is arranged on the door or a door, which generates a touch signal when touched by a person, in an evaluation after verification and verification of the transponder signal only on an unlocking signal the motor unit is transmitted when a touch signal is generated at the same time. In this way, a keyless entry door opening with easy operation should be possible.

The invention has for its object to provide a locking system for a building door of the type described above, which is characterized by an increased ease of use or ease of use.

To solve this problem, the invention teaches in a generic locking system for a building door of the type described above, that with the control of the closing device actuated, z. B. the lock is unlocked by or after an authorized terminal is logged in the communication unit. According to the invention, therefore, a keyless entry system based on a basically known Radio network communication unit (eg SmartConnect) provided. The unlocking of the lock or the actuation / release of the locking device takes place in the sense of a "keyless entry" due to the automatic establishment of a network connection and consequently an application of the terminal in the communication unit. The invention is based on the recognition that network connections in the known devices are usually automatically restored after initial setup, as soon as the terminal is within range of the network. In practice, this means that a terminal (eg a smartphone) automatically reconnects to the communication unit (eg SmartConnect) and thus "logs in" if its network is within range.

The communication unit is thus able to recognize that a particular terminal, e.g. a smartphone of an authorized user has logged in (again) to the network. The communication unit can now connect this event with an automatic action and thus open or unlock the door lock in the sense of a "keyless entry".

This can be implemented in a very simple and user-friendly manner so that the controller unlocks the lock after an authorized terminal has been registered in the communication unit (and is consequently connected to it), without necessarily having to take another active action with the terminal.

It is therefore not necessary that a separate opening command is transmitted to the communication unit with the terminal. The opening can be made automatically as soon as the terminal is (again) logged in to the network.

An application of the terminal in the network means in the context of the invention that a fundamentally deposited as authorized in the communication unit terminal is integrated into the network and thus connected to the communication unit.

Although it is basically possible and very easy for the lock to be unlocked immediately without any further action by the user when the terminal is registered in the communication unit (eg SmartConnect), there is still the possibility of increasing this security "two-stage" design. Thus, the invention proposes in a preferred embodiment that with the control of the lock (only then) can be unlocked, provided that an actuating signal is transmitted to the controller or the communication unit, while at least one authorized terminal is logged in the communication unit. Consequently, in this two-stage embodiment of the invention, the lock is only unlocked when, on the one hand, the terminal (eg smartphone) has registered in the WLAN network and, on the other hand, the user performs a specific action, eg touching a handle bar on the door. Thus, preferably, an actuating device may be provided in the region of the building door, which has a transmitter for the transmission of an actuating signal to the controller or to the communication unit. This actuating device may be, for example, a push button, a touch sensor, a contactless sensor or an identification unit with an identification query. Alternatively, the identification of a movement pattern or camera image for generating an actuation signal is possible. Such an actuation signal, which is linked to the opening of the lock with the registration of the terminal in the communication unit, but may alternatively by the query of the location (eg the terminal) or a specific gesture with the terminal. Corresponding options can be selected in the communication unit control app installed on the terminal.

The communication unit forms a network server that communicates with actuators and sensors and processes information for communication over an IP network (gateway). All relevant information is stored in the communication unit. The representation and manipulation of the information contained in the communication unit by authorized users takes place on the terminal which operates as a network client. These "clients" are terminals with visual display and / or corresponding input options. It can be a mobile phone, in particular a smartphone or a tablet with a touch display or a PDA. Alternatively, a computer, e.g. a workstation, a laptop or a notebook (with a browser) are used. The communication between server and client takes place e.g. via the TCP / IP protocol, preferably via WLAN and expediently encrypted. Data storage on the Internet (in a cloud) is not required.

The local radio network is preferably designed as a WLAN according to the IEEE 820.11 standard, which operates at frequencies from 2 GHz to 6 GHz. The terminals communicate with the communication unit via this local radio network. The communication of the communication unit with the controller takes place - as in conventional radio keys - by radio, z. B. with a frequency between 500 MHz and 1000 MHz, eg 868.3 MHz. Correspondingly, communication between the actuating device and the controller and between the actuating device and the communication unit can also take place by radio. The communication unit can communicate with the terminal itself as a WLAN access point without that an "existing" WLAN must be available. Via the terminal, the user can connect the terminal in the WLAN settings with the communication unit and then access it via the app without restrictions. This allows fast and easy use without existing WLAN. Alternatively, however, it is also possible that the communication unit can be integrated into an existing WLAN with access point / router.

The invention also provides a method for operating such a locking system for a building door. This method is characterized in that the controller actuates the closing device, for. B. the lock unlocked after an authorized terminal is registered in the communication unit. The unlocking can take place immediately when the registration of the terminal in the communication unit, that is, when the terminal comes within the range of the wireless network, without further action by a user are required for unlocking.

In a preferred embodiment, the controller unlocks the lock (only) when an actuation signal is transmitted to the controller or the communication unit, while at least one authorized terminal is registered in the communication unit. The actuation signal may e.g. with a separate actuator, e.g. the sensor already described, are generated. Alternatively, however, an actuation signal can also be generated with the terminal. In this respect, a two-stage process can be implemented.

To increase safety, it is possible to optionally set a time frame for the mentioned embodiments. Thus, the invention proposes that the controller unlocks the lock only when the actuation signal is generated within a predetermined time window after registration of the terminal in the network. Such a time window can be selected, for example, with the terminal and stored in the communication unit. So it is possible, for example, that the door is unlocked only if after logging on the terminal in the WLAN within 30 seconds, the handle bar is touched or a similar action is taken. In this case, further restrictions can be implemented, for example, the specification of certain times of day or the limitation to one-time execution of this comfort function per day. So there is z. For example, it is also possible to block access for a specific time interval if access has previously been granted. Such a temporal restriction can z. B. be useful for locking systems for certain security areas, so that then after access of a person only after a certain time interval again access is possible. Overall, the functionality can be additionally secured with such measures. The order described can also be reversed. Thus, there is the possibility that the controller unlocks the lock only when the terminal is logged within a predetermined time window after generation / transmission of the actuating signal.

The invention has been explained by way of example with reference to a preferred embodiment, in which the locking system has a motor-operated lock as the closing device, which can be unlocked or unlocked via the controller. This means that the controller transmits a corresponding command or a signal for unlocking the lock to the lock or to the motor. The invention also includes locking systems with other electrical or electronic locking devices, eg. B. with an electronic lock cylinder or an electrical or electronic fitting. In such a case, the controller can operate this locking device, in the z. B. the electronic lock cylinder is unlocked or in the z. B. is released in an electronic fitting of the door handle. The above embodiments can also be realized in such a locking system.

Optionally, visual or audible indications may be provided to indicate to the user the activation / deactivation of functions. Thus, e.g. the release will be displayed at the door or nearby when a terminal has been registered. It can also be displayed on the terminal when an actuation signal has been generated.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment.

The single figure shows schematically simplified a locking system according to the invention or its operation.

In the figure, a locking system for a building door 1 with a motorized lock 2 and a controller 3 is shown. The motor-operated lock 2 is particularly preferably a multi-point lock with a central lock and one or more additional locking devices, which are connected via a drive rod to the central lock. The lock 2 is equipped with a motor. For this purpose, a (separate) motor unit 4 may preferably be provided, which is also connected via the drive rods with the central locking and / or the additional locks. At least one unlocking of the lock 2 takes place via the motor. The locking can optionally take place mechanically in the sense of a self-locking mechanism (semi-motorized lock). The invention also includes fully motorized locks, in which both the Locking as well as the unlocking takes place. The controller 3 can be arranged directly on the lock (eg on or in the motor unit). However, it can be arranged as (separate) control 3 on the door leaf or on the door frame and be connected, for example, wired to the lock or the motor unit 4.

In the controller 3, a plurality of electronic keys (not shown) (e.g., radio hand transmitters, transponders, wireless finger scanners, or the like) may be stored, with which the lock 2 (of authorized persons) can be unlocked. For this purpose, such radio keys communicate by radio with the controller by transmitting an opening signal by radio to the controller 3. In practice, e.g. worked with a frequency of 868.3 MHz. The use of such radio keys and the communication with the controller 3 are known. Details are not shown.

According to the invention, a communication unit 5, which serves as a network server and is integrated in a local radio network (or provides such a local radio network as an access point), is arranged within the radio range of the controller 3. Such a communication unit 5 also has a transmitter for the transmission of an opening signal 6 via radio to the receiver of the controller 3. In addition, the communication unit 5 preferably has a receiver for the reception of radio signals, for example from the controller 3. Such a communication unit 5 can consequently be used as a radio key in the controller as an "authorized user". For this purpose, one or more terminals 7 (eg smartphones) operating as network clients can be stored in the communication unit 5 and then - if they are within range - logged in. The communication between the terminal 7 and the communication unit 5 takes place via the WLAN technology. In the terminal 7 (eg smartphone) in a suitable application software (eg App) installed, via which a simple operation and in particular user management is possible. Thus, a plurality of terminals 7 can be trained in the communication unit 5 and managed by the terminals 7. In this way, individual uses can be defined and temporary specifications or blockages implemented. Security is also enhanced by recording operations and setting changes in a journal. In the communication unit 5 is a separately provided WLAN module, which is preferably equipped with a power supply and is plugged into a power outlet 9 in the vicinity of the door in a simple manner.

According to the invention, a keyless entry system is now realized on the basis of such a communication unit. Because the controller 3 unlocks the lock 2 after an authorized terminal 7, which was previously registered as an authorized terminal, is registered in the communication unit 5 and consequently in the radio network. Consequently, if a user approaches the building door 1 with an authorized terminal and then enters the range of the radio network, unlocking of the lock 2 can take place automatically without any further action being necessary.

In the figure, while a preferred embodiment of the invention is shown, which operates in two stages and in which consequently unlocking the lock 2 is not already done when the terminal comes into the range of the wireless network and is therefore logged, but it is a "confirmation" required by another action. For this purpose, an actuator 10 is provided in the illustrated embodiment, which in this case arranged by the handle bar of the door or one on the handlebar Sensor is formed, with this actuator 10, an actuating signal 11 is generated and transmitted to the controller 3 or to the communication unit 5. In this case, the controller 3 unlocks the lock 2 only when an operation signal is transmitted to the controller 3 or the communication unit 5, while at least one authorized terminal 7 is registered in the communication unit 5. An active action on the terminal 7, for example, the active transmission of an opening command, is not required. It is possible that the lock will automatically open when the user approaches the door with the terminal 7 and thus enters the reach of the radio network and then touches the handle bar 10 and thus a sensor. In this way, a true keyless entry system is thus provided.

The actuating device 10 can optionally also be formed by a button in the region of the door another contact sensor, a non-contact sensor or an identification unit with identification query. Preferably, however, an action is required because no opening of the door is made anyway. In any case, such an actuation signal 11 is linked to the registration of the terminal in the WLAN network and unlocking of the door lock 2 takes place only if the connection is successful. Optionally, an actuation signal 11, 8, which is generated with the terminal 7, can also serve for the connection. by eg a certain gesture with the terminal is required or the location of the terminal is queried. In this way, the safety can be further increased without the operating comfort is significantly limited. The various scenarios may preferably be set in the app by the authorized user.

Further optimization is possible by optionally setting a time frame for the execution of the various actions or for the existence of the conditions mentioned. For example, there is the possibility that the controller 3 unlocks the lock 2 only when the actuation signal 11 (for example, via the door handle) is generated within a predetermined time window after the terminal 7 has been registered. In an alternative sequence, the controller 3 can unlock the lock 2 (only) if the terminal 7 is logged within a predetermined time window after generation / transmission of the actuation signal 11.

The time window may e.g. selected with the terminal 7 and stored in the communication unit 5. Suitably, e.g. a time window of the order of 30 seconds. Other restrictions, such as the specification of certain times of the day or the limitation to one-time execution of this comfort function per day, may also be provided and optionally selected on the terminal.

Incidentally, it is shown in the figure that the communication unit 5 can communicate with the terminal 7 as a WLAN access point without having to have an "existing WLAN" available. Via the terminal, the user can connect the terminal to the communication unit 5 in the WLAN settings and then access them without restrictions via the app. This allows fast and easy use without existing WLAN.

Alternatively, however, it is also shown in the figure that the communication unit can be integrated into an existing WLAN with access point / router 12.
