Abstract

The invention relates to a building door system (1) comprising operating and wayfinding devices (6), wherein each of the operating and wayfinding devices is assigned to a respective individual door system (2) and can be connected to one another for communication by means of a communications network (8). Each operating and wayfinding device (6) has a storage device (36), in which an identifier of the operating and wayfinding device (6) is stored, a control and processing device (30), a recognition device (44) for detecting a credential of a person (4), and a display device (32), which has a user interface (33) facing outdoors. When a credential which is not valid for the individual door system (2) is detected, the control and processing device (30) generates a request signal containing data of the credential (ID) and the individual identifier and feeds this into the communications network (8). The control and processing device (30) receives a response signal via the communications network (8), extracts wayfinding information contained in the response signal and assigned to the credential, and activates the display device (32) to display the wayfinding information on the user interface (33).

Description

BUILDING DOOR SYSTEM WITH OPERATING AND GUIDANCE DEVICES

Description

The technology described herein relates generally to a building door system for a building. Embodiments of the technology also relate to a method for operating the building door system.

Doors for buildings can be designed in a wide variety of ways in order to grant or deny people access to a building and/or a restricted-access zone in the building. The design of a building door can relate to the way in which people are granted or denied access, for example by a hinged (swinging) door or a sliding door. A single-action door has a movable door leaf, which is rotatably attached to the door frame (frame, door lining) with two or more hinges (door hinges). For example, EP 2 8166 241 B1 describes a sliding door system in which a sliding door is slidable in a frame structure between a closed position and an open position. In the closed position, the sliding door is flush with the surrounding wall, and in the open position, a recess in the wall at least partially accommodates the sliding door.

These doors can be locked and unlocked in a known manner. It is known, for example, that an electronic lock is arranged on a swing door, at which proof of authorization (eg access code, chip or magnetic stripe card) must be entered so that the door can be unlocked and opened. WO 2020/126483 A1 discloses a detection device which, for. B. is arranged on a sliding door system. A proof of authorization recorded by the recognition device and presented by a user can then be checked for validity. The recognition device can be, for example, a transmitter and receiver for radio signals, a device for detecting a biometric feature, a device for detecting an optical code, a reader for a chip or magnetic stripe card, or a keyboard or a touch-sensitive screen for manual entry of an access code or a mechanical one or include electronic door lock. The building doors mentioned relate to different requirements, for example a sliding door takes up less space than a swing door and an electronic identification device can offer greater security and convenience than a conventional door key. In addition to these requirements, further requirements arise, for example due to changing lifestyles or living conditions (e.g. densely populated living in apartments in a city), including a need for increased security and increasing automation of and in buildings. There is therefore a need for a technology that fully or partially meets one or more of these requirements, with the need for security and user-friendliness in particular being improved.

One aspect of such a technology relates to a building door system that includes a number of operating and routing devices that are each assigned to a single door system and can be communicatively connected to one another by a communication network. Each operating and routing device has a memory device in which an identifier of the operating and routing device is stored, and a control and processing device which is connected to the memory device. In addition, there is a recognition device, which is communicatively connected to the control and processing device, for detecting a proof of authorization from a person, with the individual door system releasing access if the proof of authorization is valid for this individual door system. A display device is communicatively connected to the control and processing device and has a user interface on the outside that can be viewed by a person who is outside. The control and processing device is designed to generate a request signal with data from the notification verification and the identifier and to feed it into the communication network when a proof of authorization is detected that is invalid on the single-door system, to receive a response signal via the communication network and to receive a response signal and the proof of authorization contained in the response signal extract associated routing information. The control and processing device is also designed to activate the display device to display the routing information on the user interface.

Another aspect of the technology relates to a method of operating the building door system. A proof of authorization of a person is detected by a detection device of an operating and routing device of a single door system, the proof of authorization on the single door system being invalid. A request signal is generated by a control and processing device of the operating and routing device, the request signal including data of the notification verification and an identifier of the single door system. The request signal is fed into the communication network by the control and processing device; a response signal is also received via the communication network by the control and processing device. Routing information contained in the response signal and assigned to the proof of authorization is extracted by the control and processing device. It also controls a display device of the operating and routing device to display the routing information on a user interface of the display device.

The technology described here creates a building door system in which existing security and user-friendliness requirements in a building are improved. A person can turn to virtually any operating and routing device installed there in the building to obtain routing information, in particular even if the proof of authorization for this operating and routing device or for its surroundings is not valid. Rather than merely telling the individual that the credential is not valid here, the individual is assisted by providing the routing information; in a large building, for example, the person does not have to go to a central reception desk or wander around the building alone (e.g. at night). Those skilled in the art will recognize that the routing information may be communicated visually and/or audibly.

One aspect of the technology also offers the advantage that it can be used both from an outdoor space and from an indoor space. From outside, a person who, for example, makes a mistake at a building door (e.g. hotel room door) is given the "correct" room number as route guidance information, e.g. B. displayed. Similarly, guidance information is notified when the person inputs a destination on the operation and guidance device from an indoor space, and guidance information on the way to the destination needed.

In an exemplary embodiment, the building door system comprises a number of individual door systems which, among other things, whose operating and routing devices are communicatively coupled to the communication network. Each single door system has a frame that can be built into a building wall and a door element that is movably arranged therein and that, when open, opens a passage between an exterior and an interior space and, when closed, blocks the passage, and a closing device that is connected to the control and processing device communicatively connected. In this exemplary embodiment, the individual door systems and their operating and routing devices are networked with one another via the communication network, so that z. B. There are also communication options between the operating and routing devices.

In one exemplary embodiment, a single-door system has an interface device that is designed to transmit the request signal to other single-door systems via the communication network and to receive the response signal via the communication network from one of the other single-door systems to which the proof of authorization is assigned and which determines the routing information. For example, a serving and routing device may send a request signal to one or more serving and routing devices, whereupon one or more serving and routing devices may respond. The request signal can, for example, ask the other operating and routing devices to which individual door system a presented proof of authorization is assigned or which destination is assigned to this proof of authorization. The single-door system in which this assignment information is stored can then transmit the response signal, including its identifier, to the requesting single-door system. In this way, for example, a building door system can be created which, during operation, represents a quasi-closed system that essentially does not require any communication with an external system (related to the building door system).

In an exemplary embodiment, a single door system has an interface device which is designed to transmit the request signal to a building management system via the communication network and to receive the response signal from the building management system via the communication network. The building management system is designed to determine the routing information. In this exemplary embodiment, the building management system can serve as a central communication node that executes various services for the building door system. In addition to determining the routing information, the building management system can manage the proof of authorization as a further exemplary service and check its validity if it is transmitted by the individual door systems in connection with the request signals. If such a building management system is provided, the building door system can be designed with less complexity.

The technology described here is not limited to any particular type of single door system. The equipment of a building with a desired single door system can therefore be chosen flexibly. A single door system can be used as a door element, e.g. B. include a hinged door, a revolving door or a sliding door. A single door system can also be designed without a door element, with access being controlled by a monitoring device, e.g. B. a video surveillance device in conjunction with an alarm device is monitored.

Flexibility in the design of the building door system or the building also exists with regard to the arrangement of the display device of an operating and routing device. The display device can be arranged on a door element or a frame of a single door system or on a building wall at a specified distance from the frame of a single door system.

In one exemplary embodiment, at least one of the operating and routing devices has a further display device. The further display device is communicatively connected to the control and processing device and has a user interface towards an interior space that can be viewed and/or operated by a person located in the interior space. The operating and routing devices can therefore be operated both by a person outside and by a person inside. In one exemplary embodiment, the at least one operating and routing device can have an optical system that is designed to generate an image of the outside space. In an exemplary embodiment, the image recording can be displayed on the user interface of the additional display device. In one exemplary embodiment, the optical system can be used in conjunction with a door viewer function. In another exemplary embodiment, the optical system can be used in conjunction with an image processing device as a device for recognizing biometric personal characteristics (e.g. for face recognition).

If, in one exemplary embodiment, an operating and routing device is equipped with a further display device, its storage device stores destinations that can be reached by a person in the building. The control and processing device is designed to trigger the additional display device to display at least one of these destinations for a destination input. The memory means, in one embodiment, stores the destination input, i. H. the destination that the person selects, for example before leaving the interior. This destination information can therefore be transmitted by the operating and routing device of this single door system in connection with a response signal as a reaction to a request signal.

In one embodiment, the control and processing device is designed to transmit the destination input to an elevator controller via the communication network, to receive an elevator allocation determined by the elevator controller via the communication network and to control the further display device, to communicate the elevator allocation, e.g. to display it. In this exemplary embodiment, too, the destination information can be transmitted by the operating and routing device of the single door system in conjunction with a response signal as a response to a request signal. In addition, the response signal may include the elevator allocation.

Depending on the design of the building, the information regarding the selected destination can also be transmitted to a possibly existing building management system and/or the elevator control. The destination information can thus be and routing device may be provided to said single door system or to said building management system in connection with a response signal in response to a request signal.

The exemplary embodiments, features and elements mentioned above and in this description can be combined in various combinations without restrictions, unless explicitly stated otherwise. These embodiments, features and elements, as well as their operation and applications, will become more apparent in light of the following description and attached drawings. It should be understood, however, that the following description and drawings are intended to be exemplary in nature and not restrictive.

Various aspects of the improved technology are explained in more detail below using exemplary embodiments in conjunction with the figures. In the figures, the same elements have the same reference numbers. Show it:

1 shows a schematic representation of an exemplary situation in a building with a building door system according to an embodiment;

2 shows a schematic representation of an exemplary embodiment of a part of a single door system with its components shown as an example;

3A-3C schematic representations of external display examples of an embodiment of a user interface of an operating and route guidance device of the building door system;

4A-4B schematic representations of display examples on the inside of an exemplary embodiment of a user interface of an operating and routing device of the building door system; and

5 exemplary signal diagrams for different application examples based on a single door system of the building door system.

1 is a schematic representation of an exemplary situation in an exemplary building with a building door system 1 and one or more floors LO, LI. The building door system 1 includes several single door systems 2. The term "building" in this description, for example, residential and / or commercial buildings, hotels, hospitals and other buildings in which People can stop to understand. If there are several floors in a building, these can be served by an elevator installation 10 in a known manner. For illustration, the elevator installation 10 is shown in FIG.

In the exemplary embodiment shown, the building has a ground floor L0 and an upper floor LI, which can be used by 4 people. 1 shows a person 4 outside the building in front of a single door system 2 (e.g. front door) and a person 4 on floor LI. For example, a person 4 may be authorized to enter the building and one or more rooms in the building; the building door system 1 can block a single door system 2 for a person 4 or release it with existing access authorization. However, person 4 cannot be authorized to access other rooms; the corresponding single door systems 2 remain locked for them.

1 shows on the upper floor LI two single door systems 2 serving as internal building doors, through which people 4 can enter and leave areas or rooms with restricted access located behind them. The building and/or individual restricted areas or rooms can be managed by a responsible person (e.g. tenant, owner, building management, etc.); the person responsible for this can issue access authorizations and store them in user profiles, e.g. B. per person 4 a user profile, in which it is determined to which area or room the person 4, and possibly at what times, is authorized to access. The person skilled in the art will recognize that the building on the ground floor L0 can also have one or more individual door systems 2, for example another front door and/or one or more interior building doors. A single single door system 2 or more than two single door systems 2 can be present on the upper floor LI. The latter can be the case, for example, in an office building, hotel or residential building in which individual offices, rooms or apartments can be entered from a common corridor.

Each of the exemplary single door systems 2 shown in FIG. 1 has a frame 2a, a door element 2b and an electrically controllable closing device 40, 42 (see FIG. 2), through which a single door system 2 can be opened and closed; Depending on the design, the single door system 2 can be locked and unlocked. In one embodiment, the closing device 40, 42 can be controlled by an electrical control signal. If the single door system 2 can be opened for a person 4, the electrical control signal activates the locking device 40, 42, as a result of which the single door system 2 is unlocked. Correspondingly, in one exemplary embodiment, the locking device 40 , 42 can be activated by an electrical control signal in order to lock the individual door system 2 . The person skilled in the art recognizes that a single door system 2 can also be configured without a door element 2b; the closing device 40, 42 is not present in this case. The entrance or the passage at the single door system 2 can then, for example, by means of a monitoring device, z. B. a video surveillance device in conjunction with an alarm device. In the following exemplary embodiments, the individual door systems 2 are each equipped with the locking device 40, 42, as a result of which an individual door system 2 can be locked and unlocked.

1 also shows operating and routing devices 6 and a communication network 8 which communicatively connects the operating and routing devices 6 to one another. The communication network 8 extends (horizontally) on floors L0, LI and (vertically) between floors L0, LI. The operating and route guidance devices 6 can be designed in such a way that user-side components are arranged on the frame 2a, the door element 2b or on a building wall and are accessible there for a person 4, e.g. B. to operate and / or to perceive communicated information, z. B. for reading displayed information. In FIG. 1, user-side components of the operating and routing device 6 are arranged on floor L0, for example on the door element 2b of the left-hand single door system 2 and next to the right-hand single door system 2; In the last-mentioned arrangement example, this happens in such a way that a person 4 perceives this as belonging to the right-hand single door system 2 . In FIG. 1, an operating and routing device 6 or its user-side components is also arranged on floor L0 next to the shaft door 14; in one embodiment, they can be arranged on the shaft door 14, for example on a shaft door frame. Depending on the design and organization of the building, a computer-aided (central) building management system 22 (BM) can be present, which includes a storage device 26 (DB) and a computer system 24 (pP). The building management system 22 is communicatively connected to the communication network 8 and the elevator controller 20 . The building management system 22 is shown as an example in the exemplary embodiment in FIG. 1 ; In this exemplary embodiment, it can be provided for managing the user profiles mentioned, checking the access authorizations and controlling the individual individual door systems 2 or their locking devices 40, 42. In another exemplary embodiment, no central building management system 22 can be provided in the building. In this case, the elevator control 20 can be communicatively connected to the communication network 8 and thus also to the individual operating and routing devices 6 . In an exemplary embodiment, functionalities of the central building management system 22 can be implemented in the building door system 1 or its individual door systems 2 and/or the operating and routing devices 6 . As stated elsewhere in this description, the individual door systems 2 or their operating and route guidance devices 6 can be networked with one another and equipped with functionalities for information processing, as a result of which an exchange of information between these system components is possible.

The person skilled in the art recognizes that the building management system 22 can be completely or partially outsourced to an IT infrastructure for so-called cloud computing (colloquially also referred to as “cloud”). This includes, for example, storing data in a remote data center, but also running programs that are installed remotely rather than locally. Depending on the configuration, a specific functionality can be made available, for example, in the (local) computer system 24 or via the “cloud”. For this purpose, for example, a software application or program parts thereof can be executed in the “cloud”. The computer system 24 then accesses this infrastructure as needed to run the software application.

In the situation shown in Fig. 1, the technology described here can be used in an advantageous manner to the building door system 1 with the highest possible degree operate in safety and comfort. Summarized briefly and by way of example, at one of the operating and routing devices 6, at which the person 4 presents the proof of authorization from outside, it is recognized that the proof of authorization for this single door system 2 is not valid if the person 4 is informed by the operating and Routing device 6 communicated this single door system 2 routing information. The notification can take the form of a display and/or a voice message. Instead of merely informing person 4 that the proof of authorization for this single door system 2 is not valid, person 4 is helped by the fact that in a hotel, for example, the routing information gives them the "correct" room number or route (e.g. by notifying them of a floor number and an elevator) to a desired destination (e.g. swimming pool or similar).

This will i.a. made possible by the operating and routing devices 6, which are communicatively networked with one another through the communication network 8. A control and processing device 30 (Fig. 2) of the operating and route guidance device 6 can generate a request signal with data of the proof of notification and an individual identifier of the single door system 2 in the event of a detected proof of authorization that is invalid on this single door system 2 and into the communication network 8 feed. Another single door system 2 or the building management system 22 can then generate a response signal and send it via the communication network 8 to the single door system 2 identified by the individual identifier. The control and processing device 30 can extract the routing information assigned to the proof of authorization from the response signal received and z. B. its display by means of a display device 32 (Fig. 2) of the operating and routing device 6 cause.

In one exemplary embodiment, the communication network 8 is configured as a communication bus system. Such bus systems for communication between multiple units in a building are known to those skilled in the art. The communication network 8 can e.g. B. as a field bus (z. B. LON bus system (Local Operating Network)) configured. This is a network technology based on the principle of distributed intelligence. All units (nodes) integrated in a LON network each have one free programmable chip (neuron) that is responsible for the bus connection and the protocol and is also available for application programs. Communication in a LON network takes place independently of a control center. The nodes exchange information directly with each other and can trigger actions at any location and with any participant within the LON network. There is a common communication protocol (LonTalk) for this. In another exemplary embodiment, the communication network 8 can be designed as a BACnet bus system (Building Automation and Control network) or as a KNX bus system.

As shown in FIG. 2, the single door system 2 or the operating and routing device 6 assigned to it has an interface device (IF) 28 which can be communicatively connected to the communication network 8 . In the exemplary embodiment shown, the request signals mentioned are sent via the interface device 28 and the response signals are received. For this purpose, the interface device 28 is also connected to the control and processing device 30 .

In addition to the components already mentioned, Fig. 2 shows, by way of example, further components of the operating and routing device 6, in particular a (second) display device 34, a storage device 36, an optical system 38 and a detection device 44, which is connected to the control and processing device 30 are. In the exemplary embodiment of FIG. 2, these components are arranged on the door element 2b; Two door leaves 50, 52 of this door element 2b are shown in FIG. 2, the door leaf 50 being arranged towards the outside and the door leaf 52 being arranged towards the inside. The person skilled in the art recognizes that the door element 2b can be designed as a hinged door (pivoting door), as a sliding door, as a roller door, as a revolving door, or the like. It is also an embodiment as a monitored passage possible, ie without the door element 2b or a similar barrier but additionally z. B. with a device for video surveillance. The person skilled in the art also recognizes that the operating and routing device 6 can be arranged in or on a building wall; In an example of a lightweight wall made of a double-shell construction made of wood or metal (post frame), which is provided with planking made of plaster or wood, the operating and routing device 6 can be arranged entirely or partially in a cavity between the planking. Referring to Fig. 2, reference numerals 50 correspond to 52 in this case the planking.

In one embodiment, the display device 32 is arranged in such a way that its display area (user interface 33) can be viewed from outside and, under certain circumstances, can be operated. The display device 32 can, for. B. in a recess in the door leaf 50 can be used. If, as shown in Fig. 2, the (second) display device 34 is provided, it is arranged in such a way that its display surface (user interface 35) can be viewed from the interior and, under certain circumstances, can be operated. The display device 34 can, for. B. in a recess in the door leaf 52 can be used.

The optical system 38 shown as an example in FIG. 2 can be used in one embodiment in connection with a door viewer function; oriented toward the exterior, the optical system 38 enables a view from the interior of an area of the exterior. The optical system 38 can be designed as an electro-optical (digital) door viewer with a digital camera, the images of which can be displayed in particular by the display device 34 . The way in which such a door viewer works is known to a person skilled in the art. It is also known that the peephole function z. B. can be activated manually or automatically (when motion is detected); it can also be activated permanently.

The recognition device 44, which is communicatively connected to the control and processing device 30, is designed to recognize a proof of authorization, on the basis of which a person 4 can prove their access authorization to a door system 2 in one configuration. The proof of authorization can, for example, be in the form of a physical key, a password to be entered manually (e.g. a numeric code/PIN code), a biometric personal characteristic (e.g. fingerprint, iris pattern, speech/voice characteristics or facial characteristics), one from a magnetic , chip or RFID card or an electronic device (based on NFC, Bluetooth or mobile communications) (e.g. access code) or an optical code displayed on a surface (e.g. barcode, matrix code (e.g . QR code) or color code) can be provided.

In one embodiment, the detection device 44 can include the optical system 38 . In connection with a device for image processing device and Evaluation of a biometric personal feature (e.g. for face recognition), the biometric personal feature can serve as proof of authorization in one embodiment.

According to the configurations mentioned, which the proof of authorization can have, the proof of authorization can be presented in different ways, for example by a deliberate manual action (e.g. entering a PIN code, showing an optical code or holding up an RFID card) or by approaching on the door in order to get within radio range of the detection device 44 (e.g. for establishing an RFID or Bluetooth connection) or in a detection range of the optical system 38. If the proof of authorization is valid for a single door system 2, the control and processing device 30 of this single door system 2 controls an actuator 42, for example, which unlocks an electromechanical locking mechanism 40 of the locking device (40, 42). The person skilled in the art recognizes that, in one exemplary embodiment, it may also be possible to open the single door system 2 without unlocking it beforehand.

The detection device 44 is designed in accordance with the proof of authorization provided in the building. This means that the recognition device 44 has, for example, a door cylinder, a detection device for a biometric feature, a detection device for an optical code (e.g. bar code (barcode), QR code and/or color code (see WO 2015/049186 A1)) , a reader for a magnetic stripe card or a smart card, a keyboard or a touch-sensitive screen for manual entry of a password, or a radio signal transmitter and receiver. In one embodiment, the digital camera of the optical system 38 can be used to capture an optical code and/or facial features. The detection device 44 can therefore include the digital camera or its functionality in whole or in part.

Those skilled in the art will recognize that, in one embodiment, the recognizer 44 may be configured for one or more of these credentials. In an exemplary embodiment according to FIG. 2, the recognition device 44 can comprise, for example, a transmission and reception device for radio signals (TX/RX) and a digital camera for detecting an optical code or a face. The optical code can be visibly printed on a carrier material or displayed on a display of a mobile phone. In one exemplary embodiment, the proof of authorization is transmitted to the recognition device 44 by radio, in particular using Bluetooth technology.

The memory device 36 is electrically connected to the control and processing device 30 . In the exemplary embodiment shown, storage device 36 has a storage area for a database and a storage area for one or more computer programs for operating single-door system 2. In one exemplary embodiment, operating single-door system 2 includes processing or forwarding a detected proof of authorization, unlocking and locking locking device 40 , 42 (including automatic opening and closing of a sliding door), processing or forwarding of messages received via the interface device 28 and processing or forwarding of commands entered on the display device 34. The computer program can be executed by the control and processing device 24 .

In one exemplary embodiment, the database stores a data record for a person 4 who is authorized to access a single door system 2 . The stored data record is also referred to below as a user profile. The user profile includes data, e.g. B. Name, information on the proof of authorization (key number, PIN code, access code, biometric data) and possibly time access restrictions (e.g. access from Monday to Friday, from 7:00 a.m. to 8:00 p.m.). If several people are authorized for access, the database stores a user profile for each person 4 .

With an understanding of the principal system components described above and their functionalities, application examples of the technology are given below in connection with FIGS. 3A-3C. Communications that take place via the communication network 8 are shown in FIG. 5 . 3A - 3C show schematic representations of display examples on the outside and on the user interface 33 of an exemplary embodiment of the display device 32 of the operating and route guidance device 6. A part of the display device 32 that is visible from the outside has an elongated shape (length and width) that each is shown in a vertical orientation. Each broadside is designed in the shape of a semicircle, with the detection device 44 arranged behind it and the optical system 38 being shown in the lower semicircular broadside for illustration. Their presence may be indicated on the user interface 33 (e.g., as shown in Figures 3A-3C by means of one or more circles and/or a light (with or without a color or light effect)); as a result, a person 4 recognizes, for example, at which point the proof of authorization is to be presented. The person skilled in the art will recognize that a horizontal orientation of the visible part of the display device 32 is also possible and that the visible part can be designed in a different way, e.g. B. can have a different shape (e.g. round or oval, with only a semi-circular broad side, etc.).

In these application examples, a person 4 is outside in the area of a single door system 2 and can view and operate the operating and routing device 6 from there. In the application examples shown in FIGS. 3A-3C, the person 4 is not authorized to access the single door system 2, but he has already presented his proof of authorization there. In FIG. 3A, the user interface 33 therefore indicates the lack of access authorization by means of a pictogram 33.1 and/or a lighting effect. In addition, the user interface 33 displays an icon 33.2 for routing information; in a hotel, for example, a number (501) of the (correct) room assigned to person 4. If the person 4 has, for example, got the room number wrong or forgotten it (because it is not specified on a “room key” in the form of a card), they can then go to “their” hotel room using the routing information displayed. The routing information includes z. B. only the room number, but it can also include other information (z. B. floor, direction and / or elevator information).

In Figure 3B, the user interface 33 displays two icons 33.3, 33.4 for routing information. The routing information instructs the person 4 to go in the direction indicated by the icon 33.4 (icon 33.3). In Figure 3C, the user interface 33 also displays two icons 33.5, 33.6 for routing information. The routing information instructs person 4 to take an elevator (icon 33.5) to the 5th floor (icon 33.6). The A person skilled in the art will recognize that the way in which the routing information is presented is neither limited to pictograms (ie simplified graphic representations for conveying information) in general, nor to the pictograms shown (or others) and their number.

As explained in connection with FIG. 2 , the operating and routing device 6 in one exemplary embodiment includes the display device 34 , the user interface 35 of which can be viewed and operated from the interior. 4A and 4B show schematic representations of display examples of an exemplary embodiment of the display device 34 shown on the inside and on the user interface 35. For this purpose, the display device 34 comprises a touch-sensitive screen (also referred to below as touchscreen). In FIGS. 4A and 4B, the user interface 35 shows a slide control 35.1, which can be moved by an indicated finger along a first (horizontal) path 35.2 and a second (vertical) path 35.3. In the exemplary embodiment shown, the webs 35.2, 35.3 extend at right angles to one another, starting from a common origin; in Fig. 4A the common origin is hidden by the slider 35.1. At the end of the first track 35.2, a pictogram 35.4 is shown for unlocking (opened padlock) or opening the door, and exemplary floors LI, L, P are shown along the second track 35.3.

In Fig. 4A, an icon for the peephole (38) is shown within the circular slider 35.1. Touching or “pressing” the door viewer pictogram activates the door viewer (38), for example, and the outside space covered by it can be displayed and observed on part of the user interface 35. If the slider 35.1 is pushed along the first path 35.2 to the (unlocking) pictogram 35.4, the single door system 2 is unlocked. Depending on the configuration of the single door system 2, its door element 2b can be opened automatically, e.g. B. a sliding door can be moved from a closed position to an open position.

If, on the other hand, the slider 35.1 is pushed along the second track 35.3 to a desired floor LI, L, P, an elevator call can be entered as a result. This is illustrated in Figure 4B. In this exemplary embodiment, the single door system 2 is connected to the elevator controller 20 via the communication network 8 (Fig. 1) communicatively connected. The elevator call received in this way by the elevator controller 20 is also referred to as a destination call because it indicates both the boarding floor (location of the person 4) and the desired floor LI, L, P (destination floor). The elevator controller 20 allocates an elevator to the destination call and transmits this allocation information to the single-door system 2. In the exemplary embodiment shown in FIG. 4B, the allocation information (elevator C) is displayed within the slide control 35.1. If the person 4 then leaves the interior in order to go to the assigned elevator (C), they can, if necessary, request routing information using the operating and routing devices 6 arranged along the route to the elevator, as described in connection with Fig. 3A - Fig. 3C is described.

Also with respect to the illustrations in FIGS. 4A and 4B , those skilled in the art will recognize that these are exemplary and not limited to the illustrations shown.

5 shows exemplary signal diagrams for different application examples A1-A6 starting from a single door system 2 of the building door system 1. In each application example A1-A4, signals as a function of time t are shown schematically and not to scale for illustration and reference. Fig. 5 schematically shows the communication network 8 as the units involved in the respective communication, with the detection device 44, the display device, the control and processing device 30 and the storage device 36 of a single door system 2 being shown on the left and the building management system 22 on the right together with the elevator control 20 and a group of the remaining operating and routing devices 6 and the individual door systems 2 are shown. The person skilled in the art recognizes that, depending on the design of the building or the building door system 1, communication can take place without the involvement of the building management system 22, the elevator controller 20 and/or the storage device 36 of the individual door system 2, as described below in connection with the application examples A1 - A4 is executed.

In the application example A1, a memory device 36 is provided on the single door system 2, in which one or more identifiers of proof of authorization are stored, which belong to one or more persons 4 with access authorization. The Detection device 44 of the single door system 2 (e.g. hotel room) at which the person 4 is located transmits an identifier ID of a proof of authorization (e.g. room key) presented by the person 4 to the control and processing device 30 (signal S10) . The control and processing device 30 thus controls the memory device 36 in order to check whether the identifier ID is stored on the single door system 2 as belonging to a person 4 with access authorization (signal SH). This check delivers either a positive (J) or a negative (N) result (signal S12). If the result is positive (Y), the single door system 2 is unlocked; the person 4 can z. B. Enter your hotel room.

If the result is negative (ID: N), the control and processing device 30 of the single door system 2 sends a request signal to the communication network 8 (signal

513) which transmits the request signal to the building management system 22 (signal S14). If the identifier is valid (ID OK), the building management system 22 determines the associated routing information (e.g. number (#) of the hotel room) and transmits this routing information by means of a response signal (addressed to the requesting single door system 2 (identifier)) to the communication network 8 (signal S15 ), which transmits the response signal to the control and processing device 30 (signal S16). The control and processing device 30 controls the display device 32 to display the routing information on the user interface 33 (signal S17). In the hotel room example mentioned, person 4 can then read off the correct room number; in Fig. 3A this is e.g. B. the room "501". If the identification ID is invalid, no routing information can be determined; in this case, a corresponding error message can be transmitted to the requesting individual door system 2 and displayed there.

In an application example not shown in FIG. 5 , no memory device 36 is provided on the single door system 2 . In this exemplary embodiment, the signals SH and S12 are omitted, and the control and processing device 30 transmits the identifier ID directly to the building management system 22 by means of the request signal (signals S13,

514). The subsequent signals (S15 - S17) correspond to those of application example A1.

In application example A2, there is a storage device 36 on the single door system 2 provided, but a building management system 22 is not provided. The identifier ID is determined and checked (signals S20-S22) as described in connection with the application example A1 and the signals S10-S12 there. If the result is negative (ID: N), the control and processing device 30 of the single door system 2 sends a request signal via the communication network 8 (signal S23) to the group of other single door systems 2 (signal S24). Each of these individual door systems 2 determines whether a proof of authorization with this identifier ID authorizes access to the corresponding individual door system 2 . The single door system 2, where this is the case, generates a response signal including the associated routing information (e.g. number (#) of the hotel room) and transmits this routing information by means of the response signal (addressed to the requesting single door system 2) to the communication network (signal S25) , which transmits the response signal to the control and processing device 30 (signal S26). The control and processing device 30 controls the display device 32 to display the routing information on the user interface 33 (signal S27). Depending on the configuration, only the individual door system 2 on which the identifier ID is valid can respond, or each individual door system 2 can be configured to respond to a request signal. If no routing information has been received (either after a specified period of time has elapsed or in the case of negative response signals), a corresponding error message can be displayed on the requesting individual door system 2 .

The application examples A3 and A4 relate to a situation in which a person 4 enters an elevator call before leaving the interior in order to get to a desired destination and requests routing information to the destination using the operating and routing devices 6 arranged along the route to the elevator. as described in connection with Figure 4B. The desired destination is assigned to an identifier ID of a credential valid for the interior (i.e. the desired destination and identifier ID form a data pair), and the information (data pair) relating to the desired destination is stored in the building management system 22 and/or in the storage device 36 of the single door system 2 . The starting point (the interior indicated by the identifier ID) and the destination are thus known in the building door system 1 . The target information remains z. B. stored for a specified period of time or until the person 4 has reached the destination. This stored destination information can be accessed when needed. Person 4 is in the application examples A3 and A4 to an operating and route guidance device 6 and presents their proof of authorization to its detection device 44; for the purposes of illustration, it is assumed that the person 4 is not "known" to this operating and route guidance device 6 or is not authorized to access the corresponding single door system 2 .

In application example A3, the detection device 44 detects an identifier ID of the proof of authorization presented by the person 4 and transmits the identifier ID to the control and processing device 30 (signal S30). In one exemplary embodiment, the control and processing device 30 can cause the identifier ID to be checked, e.g. B. described in connection with the signals Sil and S12 of the application example A1. Because of the above assumption, there is a negative result (ID: N). In this case, the control and processing device 30 generates a request signal and transmits it to the communication network 8 (signal S31). The request signal includes the identifier ID and an identifier of the requesting operating and routing device 6. The communication network 8 transmits the request signal according to the application example A3 to the building management system 22 (signal S32).

The desired destination associated with the identifier ID is stored in the building management system 22 . If the building management system 22 receives the identifier ID, it determines the destination associated with the identifier ID and generates a response signal. The response signal includes the routing information (DEST) to get from the location of the requesting operating and routing device 6 to the destination. The building management system 22 transmits the routing information (DEST) by means of the response signal (addressed to the requesting operating and routing device 6) to the communication network (signal S33), which transmits the response signal to the control and processing device 30 (signal S34). The control and processing device 30 controls the display device 32 to display the routing information on the user interface 33 (signal S35). In the elevator call example mentioned, the person 4 can then record the routing information, as illustrated by way of example in FIGS. 3B and 3C.

No building management system 22 is provided in application example A4, so that the control and processing device 30 (directly) communicates with the group of other operating and routing devices 6 or the group of the remaining single door systems 2 communicates. The detection device 44 detects the identifier ID of the proof of authorization presented by the person 4 and transmits the identifier ID to the control and processing device 30 (signal S40). As in application example A3, there is also a negative result (ID: N) in application example A4, whereupon control and processing device 30 generates a request signal and transmits it to communication network 8 (signal S41). The request signal includes the identifier ID and an identifier of the requesting operating and routing device 6. The communication network 8 transmits the request signal according to the application example A4 to the group of other operating and routing devices 6 or the individual door systems 2 (signal S42).

Each of these individual door systems 2 determines whether there is chronologically valid destination information for this identification ID. The single door system 2, where this is the case, generates a response signal including associated routing information based on the location of the requesting operating and routing device 6 and transmits this routing information by means of the response signal (addressed to the requesting operating and routing device 6) to the communication network (signal S43), which transmits the response signal to the control and processing device 30 (signal S44). The control and processing device 30 controls the display device 32 to display the routing information on the user interface 33 (signal S45).

In order to determine 5 the wayfinding information according to the application examples A3 and A4, the operating and wayfinding devices 6 and/or the building management system 22 can access a location and building plan defined and stored for the building, e.g. B. by means of a search query in a database facility (e.g. route from location to destination). In a site and building plan of a building z. B. for each floor, the rooms, corridors, halls, stairs, elevators and / or escalators can be shown true to scale. The location and building plan can be stored in a storage device provided for this purpose, which z. B. can be arranged in the building management system 22. In one exemplary embodiment, each of the operating and routing devices 6 can have such a storage device or be connected to it.
