The elevator car, when operated by the elevator controller (15), can move from a first floor (L, F1, F2) to a second floor (L, F1, F2) by means of a drive motor (14). The elevator operating devices are connected to the elevator controller (15). One of the elevator operating devices (6) has a control device (40, 42) and a screen device (24), wherein the control device (40, 42) receives data for optical encoding (26) and data for floor indicators (28) from the elevator controller (15), and operates the screen device (24) based on the data for optical encoding (26). The screen device (24) displays the optical encoding (26) in a first display field (30). In addition, the control devices (40, 42) are designed to operate the screen device (24) to display floor indicators (28) in the first display field (30), detect touches by users (4, 5) on the optical code (26) shown in the first display field (30), and generate an elevator call for the floor (L, F1, F2) indicated by the floor indicator (28) when a touch is detected.

Description

Technical Field

[0001] The technology described herein generally relates to a control device for elevator equipment and its operation in a building. Embodiments of this technology particularly relate to an elevator system in which an elevator controller assigns elevator calls input to the elevator control device, and to a method for operating such an elevator system. Background Technology

[0002] In buildings with elevators, elevator control units are located on each floor, allowing users to call the elevator. In widely used elevator systems, the floor-mounted controllers have up / down buttons so users can input their desired direction of travel. The elevator car also includes facilities allowing users to input their desired floor within the car. In other known elevator systems, users can input their target floor on the elevator controller. For this purpose, elevator systems are equipped with target call controllers. Floor-mounted elevator control units for inputting targets include electromechanical buttons, touchscreens, RFID readers (as known in EP0699617B1), or (Bluetooth) radio modules (as known in EP2238067A1). For operating the elevator, as known in EP3536647A1, matrix codes (quick response, QR codes) are placed on or near the elevator floors. Users can use mobile phones / smartphones to read the QR codes to input a call.

[0003] The aforementioned feasible solutions for call input each have their advantages and disadvantages. For example, requiring users to touch electromechanical buttons or touchscreens may be undesirable, especially during a pandemic. Call input using RFID readers or mobile phones requires users to operate the RFID card or mobile phone, which can be time-consuming and therefore undesirable. Summary of the Invention

[0004] Therefore, there is a need for a technology for inputting calls into elevator equipment that can improve the ease of operation for a wider range of users with different concerns without increasing the technical complexity of the elevator equipment.

[0005] One aspect relates to an elevator system comprising an elevator controller, an elevator car, and multiple elevator operating devices arranged on floors of a building. The elevator car, when operated by the elevator controller, can move from a first floor to a second floor by means of a drive motor. The elevator operating devices are connected to the elevator controller. One of the elevator operating devices includes a control unit and a screen unit. The control unit is designed to receive data for optical encoding and data for floor indicators from the elevator controller, wherein the data for optical encoding and the data for floor indicators are stored in the elevator controller as associated with the same floor. The control unit is also designed to operate the screen unit according to the data for optical encoding, wherein the screen unit displays the optical encoding in a first display field, and to operate the screen unit according to the data for floor indicators to display the floor indicators in the first display field, wherein the floor indicators and the optical encoding are perceptible to a user. The control unit is also designed to detect a user touch on the optical encoding displayed in the first display field, and when a touch is detected, to generate an elevator call for the floor indicated by the floor indicators.

[0006] On the other hand, a method for operating an elevator system is disclosed, the elevator system comprising an elevator controller, an elevator car, and a plurality of elevator operating devices arranged on the floors of a building, the elevator car being able to move from a first floor to a second floor by means of a drive motor when operated by the elevator controller. The elevator operating devices are connected to the elevator controller, wherein at least one elevator operating device has a control device and a screen device. According to the method, the screen device is operated to display an optical code and a floor indicator in a first display field, the operation being based on data received from the elevator controller for the optical code and data received from the elevator controller for the floor indicator. When a user touches the optical code displayed in the first display field, the screen device generates an electrical detection signal. When the electrical detection signal is present, an elevator call is generated and transmitted to the elevator controller, wherein the elevator call indicates the floor indicated by the floor indicator.

[0007] The technology described herein proposes an elevator controller that allows elevator calls to be entered manually or via a communication device (e.g., a smartphone). The elevator control device displays a display field in which an optical code that can be detected and processed by the communication device is shown. In addition to the optical code, the screen device also displays a floor indicator in the display field, which visually or readablely indicates to the user which functions and / or information are assigned to the display field or the optical code. The floor indicator specifically indicates to the user the floor assigned to the display field and which can be entered by the user as the target floor. The elevator control device is designed to recognize touch on the display field or the optical code displayed therein as input for an elevator call. A user carrying a mobile communication device can, for example, choose how they wish to enter the elevator call. This choice can be based, for example, on whether touching the surface of the elevator controller should be avoided for hygiene reasons, or whether the communication device is available (e.g., on hand and / or ready for use). If the goal is to enter the call as simply and quickly as possible, touching the elevator controller with a finger may be faster than operating a communication device that may first require unlocking.

[0008] In one embodiment, the elevator control device can display multiple display areas. The control mechanism of the elevator control device is designed to operate the screen device and display at least one second display area. The first display area and at least the second display area can be perceived by the user spatially separate from each other. This allows the elevator control device to flexibly adapt to the building-specific requirements of the elevator equipment.

[0009] Due to the aforementioned feasible options regarding the type of call input (manual or with the assistance of a communication device), call confirmation or dispatch information can be flexibly sent to the elevator operating device or the communication device. In one embodiment, the control device is designed to operate the screen device to display the elevator identifier assigned to the elevator call in a first display field or another shown display field. When the identifier is displayed in the first display field, it can be displayed alternatively using optical encoding; the identifier is displayed for a defined duration.

[0010] In addition to flexibility, the technology described herein also provides security against misuse. In one embodiment, the elevator controller is designed to generate data about the new optical code at regular or random time intervals and send that data to the elevator operating device. The control device manipulates the screen device based on the data about the new optical code, thereby displaying the new optical code in a first display field. Attached Figure Description

[0011] The various aspects of the improved technique will now be explained in more detail with reference to the accompanying drawings and embodiments. In the drawings, the same elements have the same reference numerals. Wherein:

[0012] Figure 1 A schematic diagram illustrating an exemplary scenario in a building with multiple floors and exemplary elevator equipment;

[0013] Figures 2A to 2D A schematic diagram showing the operation of the elevator control device during an exemplary call input;

[0014] Figure 3 A schematic block diagram illustrating an embodiment of an elevator control device is shown.

[0015] Figure 4 Example illustrations showing embodiments of a method for operating an elevator control device; and

[0016] Figure 5 Example illustrations show an embodiment of a method for operating elevator equipment using an elevator control device, which can be based on... Figures 2A to 2D run. Detailed Implementation

[0017] Figure 1 This diagram illustrates an example scenario in a building 2 with multiple floors F1, F2, L served by an exemplary elevator system 1. For the reasons illustrated, in... Figure 1 Only selected components and subsystems of elevator equipment 1 are shown: elevator controller 15 equipped with a target call controller; drive motor 14; hoisting device 16 (e.g., steel cable or flat belt); elevator car 22 (hereinafter also referred to as car 22) suspended on hoisting device 16 and capable of moving within shaft 18; and devices (6, 10) for inputting elevator calls. Those skilled in the art will appreciate that elevator equipment 1 may also include multiple cars 22 located in one or more shafts 18, which may be controlled by a group controller. Instead... Figure 1 The traction elevator shown in the diagram, elevator equipment 1 may also have one or more hydraulic elevators.

[0018] exist Figure 1In the illustrated embodiment, the elevator controller 15 includes two subsystems (call dispatch system 8 and control system 12). The call dispatch system 8 includes a computer that dispatches elevator calls to the elevator car 22 to serve the call according to a dispatch algorithm. In one embodiment, the elevator call is a target call, whereby users 4 and 5 notify the elevator controller 15 of their desired target floor; thus, information about the boarding floor and the target floor exists in the elevator controller 15 before users 4 and 5 enter the elevator car 22. Call dispatch can be performed by the computer alone or in conjunction with the elevator equipment 1's devices (6, 10) for inputting elevator calls. Such dispatch algorithms are known to those skilled in the art; dispatch algorithms that work in conjunction with call input devices are described, for example, in the following literature: Koehler, Jana, et al., An AI-Based Approach to Destination Control in Elevators, AI Magazine, Vol.23, No.3, 2002, pp.59-78.

[0019] The call dispatch system 8 also includes means for sending and receiving signals via the communication network 20. Because the call dispatch system 8 establishes a connection between the components connected to the communication network 20 and the computer of the call dispatch system 8, it can also be referred to as a Destination Call Gateway (DCG). The control system 12 primarily manipulates the drive motor 14 in such a way that the dispatched car 22 moves from the boarding floor to the destination floor. Those skilled in the art will recognize that the elevator controller 15 may include other subsystems and components configured for various functions and tasks.

[0020] In the illustrated embodiment, at least one device (6, 10) is arranged on each floor L, F1, F2, by means of which users 4 and 5 can input elevator calls. Hereinafter, device 6 on floors F1 and F2 will be referred to as "elevator operating device 6," and device 10 on floor L will be referred to as "floor call device 10." The arrangement of devices 6 and 10 is not limited to... Figure 1 The arrangement shown, for example, allows the floor call device 10 to be arranged on one of floors F1 and F2, or the elevator operating device 6 to be arranged on floor L. Additionally, more than one device 6, 10 can be arranged on floors L, F1, and F2. In one embodiment, the elevator operating device 6 can be arranged on all floors L, F1, and F2.

[0021] Each elevator control device 6 has a screen device 24 on which at least one display area 30 can be displayed so that it is perceptible or visible to users 4 and 5. In one embodiment, the screen device 24 is designed to identify whether and where users 4 and 5 touch the user-side surface of the screen device 24. Such a screen device 24 may also be referred to as a touchscreen device 24 or a touchscreen. The functions and structures of touchscreens are generally known to those skilled in the art.

[0022] exist Figure 1 In the illustrated scenario, the screen device 24 of the elevator operating device 6 on floor F1 displays, for example, only one display field 30, while the screen device 24 of the elevator operating device 6 on floor F2 displays, for example, two display fields 30. These display fields 30 respectively display optical codes 26 and floor indicators 28. The optical codes 26 and floor indicators 28 essentially form a pair, wherein the floor indicators 28 visually or readablely indicate to the users 4, 5 which function and / or information corresponds to the display field 30 or the optical codes 26. Figure 1 In the middle, functions such as call input for travel requests from floor F1, F2 to floor L or from floor F2 to floor F1 are provided.

[0023] The optical code 26 can be designed in various ways, as long as it can be mechanically read and further processed using an optical reading device. In the embodiment described herein, the optical reading device is a camera present in the communication device 9 (e.g., a mobile wireless device / mobile phone, smartphone, tablet). The optical code 26 may, for example, include an illustration of alphanumeric strings and / or lines or dots of varying widths and gaps with the highest possible contrast between them. The illustration may not be a one-dimensional barcode or a two-dimensional (2D) code. Examples of 2D encoding include 2D barcodes (e.g., stacked codes or code 49) and matrix encodings (e.g., Quick Response (QR) encoding, data matrix encoding, JAB color encoding). Such encoding and its generation methods are known to those skilled in the art, and therefore further schemes appear unnecessary here.

[0024] like Figure 1 and Figures 2A to 2D As shown, for example, QR codes are displayed as optical codes 26 in display field 30, and the character "L" representing floor L is displayed as a floor indicator 28. In one embodiment, the elevator control device 6 on floors F1 and F2 can display different floor indicators 28, such as... Figure 1As shown on floor F2. Those skilled in the art will understand that the floor indicator 28 is not limited to a single character (e.g., "L"), but can be designed in various ways, as long as the user 4, 5 can read the floor indicator 28 and assign it meaning. Therefore, the floor indicator 28 can include numbers, one or more letters (text), alphanumeric strings, symbols, pictographs, or combinations of these options. Those skilled in the art will also understand that, in another embodiment, the screen device 24 can display multiple display fields 30 with or without optical codes 26. When multiple optical codes 26 are displayed, these optical codes must be arranged on the screen 24 in such a way (e.g., at a sufficient distance) that these optical codes can be read individually by the camera. The functions of the optical codes 26 and the floor indicator 28 are explained elsewhere in this specification.

[0025] Floor L can be the entrance hall of building 2, through which users 4 and 5 enter and exit building 2. When users 4 and 5 reach floor L, they can then, with appropriate access authorization, use elevator equipment 1 to reach each floor F1 and F2 of building 2. Elevator operating devices 6, floor call devices 10, or combinations of these devices 6 and 10 can be installed on floor L. For illustrative purposes, in... Figure 1 Only the floor call device 10 is located on floor L.

[0026] exist Figure 1 The illustration exemplifies a floor call device 10, which includes, for example, a button 10a and a display device 10b. This means that users 4 and 5 on floor L can input an elevator call (target call) to any target floor using the button 10a, and the display device 10b will inform users 4 and 5 of the elevator car 22 serving the call. Alternatively, a touchscreen, RFID reader, reader or display device for optical encoding (e.g., barcode, QR code, or color code), or a radio module communicating with user 5's portable communication device 9 can be used to implement the call input. Those skilled in the art will understand that even with these alternatives, users 4 and 5 are still informed of the elevator car 22 serving the call.

[0027] For the purpose of illustrating and describing the embodiments, Figure 1Two categories of users, 4 and 5, are shown. According to the first category, user 5 can be, for example, someone who lives or works in building 2; these users 5 may each carry a mobile electronic communication device 9 (e.g., a mobile wireless device), which is primarily designed for operating elevator equipment, as described in more detail elsewhere in this specification. Users 5 are, for example, marked on floors F1 and L. According to the second category, user 4 can be, for example, a visitor who stays in building 2 intermittently and does not necessarily carry a communication device 9 designed for operating elevator equipment. User 4 can also be someone residing in building 2 who does not carry a communication device 9 or is unable or unwilling to use a communication device. Figure 1 The image shows user 4, who does not have communication device 9. User 4 is, for example, plotted on floors F1 and F2.

[0028] exist Figure 1 In the scenario illustrated, the techniques described herein can be advantageously used. Simply and exemplarily, users 4 and 5 can input an elevator call on the elevator control device 6 according to the techniques described herein by touching display field 30, particularly by touching the optical code 26 displayed in the display field, or by reading the optical code 26 shown via communication device 9. For this purpose, screen device 24 is operated such that, in addition to the optical code 26, a floor indicator 28 is displayed in display field 30, and a touch of display field 30 (where the optical code 26 can also be touched) is recognized as an input elevator call. Floor indicator 28 displays the target floor assigned to display field 30 to users 4 and 5. Therefore, users 4 and 5 can choose how they wish to input the elevator call. The choice can be based, for example, on whether touching screen 24 should be avoided for hygiene reasons, or whether communication device 9 is available (e.g., on hand and / or ready for use), or whether the call input should be performed as quickly as possible; tapping display field 30 with a finger may be faster than operating communication device 9, which may first require unlocking.

[0029] exist Figures 2A to 2D The diagram illustrates an exemplary working principle of the elevator control device 6 during call input. Here, the elevator control device 6 is designed to display a second field 32 in addition to the first display field 30 on its screen device 24. This field 32 can be implemented identically to the display field 30, which serves as a display field for both input and display, or it can be implemented as a display field that can only be displayed. Those skilled in the art will also understand that the screen device 24 can display other fields. As described above, users 4 and 5 can touch... Figure 2A The display field 30 shown can be used to read the displayed optical code 26 via the communication device 9. The display field 30 also shows the target floor (L) (floor indicator 28) corresponding to the optical code 26. Figure 2B The image shows users 4 and 5 touching optical code 26 with their fingers to input an elevator call requesting a journey from the floor they are going to to the destination floor (L). The call dispatch system 8 dispatches an elevator for this call and informs users 4 and 5 of the dispatched elevator. Figure 2C In this context, notification is issued by displaying the assigned elevator (e.g., elevator A) in domain 32. Those skilled in the art will understand that the elevator control device 6 can additionally generate an audible notification. According to... Figure 2D In one embodiment, the screen device 24 can be manipulated in such a way that the assigned elevator is displayed in the display field 32 for a defined duration (e.g., 12 seconds) instead of the optical code 26.

[0030] As Figure 2B As shown in the touch screen alternative, user 5 can use communication device 9 to read optical code 26. Those skilled in the art will understand that when the floor call device 10 on floor L displays the optical code, communication device 9 can also be used to read the optical code on floor L. Those skilled in the art will also understand that the optical codes 26 displayed on floors L, F1, and F2 are floor-specific; that is, elevator controller 15 stores which optical code 26 is displayed on which floor and on which floor call devices 6 and 10. Thus, control devices 8 and 12 can identify which floor L, F1, or F2 is used to enter a call. Optical code 26 can be constant over time or change (dynamic). Dynamic optical codes can change periodically or at random intervals. This ensures (and prevents abuse) that user 5 is directly located at the corresponding call input device 6 or 10 when entering a call.

[0031] When the communication device 9 is, for example, a smartphone, dedicated software (also known as an "App") can be installed on it. This software reads and further processes the optical code 26. The communication device 9 communicates with the elevator controller 15 via an intra-building communication network and / or a mobile radio network. The elevator controller 15 receives information including the target call along with relevant information about the floor to be reached and the destination floor, and initiates elevator dispatch. Those skilled in the art will understand that the dispatched elevator is also communicated to the user 5; the dispatched elevator may be displayed, for example, on the screen of the communication device 9 and / or sent as a voice message. An example of an application (App) suitable for this purpose is the Schindler Group's myPORT application.

[0032] Depending on the design of the elevator device 1 and / or the application, a user interface can be displayed on the screen of the communication device 9, which enables the operation of the elevator device 1 via the communication device 9. In one embodiment, when the user 5 uses the communication device 9 to read the optical code 26, the application can automatically generate a target call to the target floor indicated by the floor indicator 28. In another embodiment, the application can suggest the target floor indicated by the floor indicator 28 on the user interface as the target floor and provide the user 5 with the possibility of confirming the suggested target floor or selecting another target floor within a defined time period; if no selection is made within this time period, the call input is canceled or a target call to the suggested target floor can be automatically generated.

[0033] Figure 1 The floor indicators 28 (“L”, “F1”) shown can be fixedly assigned to elevator operating devices 6; that is, the elevator operating devices display floor indicators 28 unchanged for a defined, relatively long period of time. This fixed assignment can be implemented, for example, in conjunction with the installation of elevator equipment 1 in building 2. In one embodiment, the fixed assignment relationship can be changed, for example, when the requirements and / or uses of building 2 change. In one embodiment, floor indicators 28 can be dynamically assigned to elevator operating devices 6, for example, based on the overall current situation in building 2 or only based on the current situation on one or a single floor F1, F2. When, for example, an activity ends on a floor, the elevator operating device 6 there can display the entrance lobby (floor L) as floor indicator 28 for that period of time, and outside that period of time, it can display another floor as floor indicator 28, such as the floor where the restaurant is located. In an office building, floor indicators 28 can, for example, display the restaurant floor during lunchtime and the entrance lobby when users 4, 5 leave building 2. Those skilled in the art will know that elevator controller 15 accordingly operates each elevator operating device 6 and stores the current assignment scheme of floor indicators 28.

[0034] The elevator operating device 6 and the floor call device 10 are connected to the elevator controller 15 via a wired network 20. The wired network 20 is designed, for example, for an Ethernet connection with the elevator controller 15. Communication between the elevator controller 15 and the aforementioned devices 6 and 10 is performed according to a protocol for wired communication (e.g., Ethernet protocol).

[0035] Figure 3 A schematic block diagram illustrating an embodiment of an elevator operating device 6 is shown, which is connected to an elevator controller 15 via a wired network 20. Figure 3The diagram shows that other elevator operating devices 6 are connected to a wired network 20. A screen device 24, control devices 40, 42, and a communication device 38 (COM) are arranged within the housing 36 of the elevator operating device 6. In the illustrated embodiment, the screen device 24 includes a lighting device 50 and a display and input device 54. Depending on the design of the elevator operating device 6, the elevator operating device may include an electroacoustic transducer 52 (e.g., a speaker) connected to the control devices 40, 42; the electroacoustic transducer 52 is shown as an optional component in dashed lines. The electroacoustic transducer 52 can be used, for example, to output voice notifications or audible tones to, for example, acoustically confirm an elevator call or announce the assigned elevator to users 4, 5.

[0036] In the illustrated embodiment, control devices 40, 42 include a central computing unit (CPU) and a processor 42, which are shown, for example, as separate components. The processor 42 is connected to the CPU 40 and the display and input device 54. For example, the processor 42 detects signals generated by the display and input device 54 when users 4, 5 touch the surface of the screen device 24. Those skilled in the art will understand that the CPU 40 and the processor 42, or their functions, can be integrated into control devices 40, 42; therefore, the functions of the processor 42 can be performed by the CPU 40, and... Figure 3 The illustration of processor 42 can be omitted. Under the control of the central computing unit 40, the display and input device 54 of the screen device 24 displays the optical code 26 (floor indicator 28) in the display field 30. Figure 3 (Not shown in the image).

[0037] The lighting device 50 is used to illuminate the user interface of the elevator operating device 6, or to illuminate only certain areas of the user interface, such as fields 30 and 32. Under the control of the central computing unit 40, the lighting device 50 can illuminate the display and input device 54 or its user interface with white light, so that the displayed information can be perceived by the users 4 and 5, especially in poor lighting conditions. The lighting device 50 can also illuminate fields 30 and 32 with colored light to confirm the elevator call input to the users 4 and 5. In one embodiment, the lighting device 48 includes one or more LED light sources.

[0038] Having understood the basic system components and their functions described above for elevator equipment 1, the following references... Figure 4 and Figure 5Exemplary methods are described. Each method is illustrated with the aid of exemplary flowcharts and the steps performed herein. Those skilled in the art will recognize that the division of these steps is exemplary, and one or more steps may be divided into one or more sub-steps, or multiple steps may be combined into one step. Reference is made to users 4 and 5, for example, located on floor F1 and calling for an elevator to proceed to a target floor from there (i.e., the boarding floor). Each elevator operating device 6 is activated and communicates with the elevator controller 15.

[0039] Figure 4 Showing the operation Figure 1 The method of the elevator operating device 6 shown. The method begins at step S1 and ends at step S6.

[0040] In step S2, a display field 30 is generated to display the optical code 26 and the floor indicator 28. Since the elevator operating device 6 communicates with the elevator controller 15 via the communication device 38, the elevator operating device 6 receives information or data about the optical code from the elevator controller 15. Based on this information or data, the elevator controller 38 generates and displays the optical code 26. The screen device 24. The optical code 26 is floor-specific. In one embodiment, the elevator operating device 6 also receives information or data about the floor indicator 28.

[0041] In step S3, the method waits for the optical code 26 or the display field 30 displaying the optical code 26 to be touched by the user 4 or 5. If no touch occurs, the method remains in standby mode, indicated by a loop returning to step S2 along the "No" branch. Conversely, if a touch occurs, the method proceeds to step S4 along the "Yes" branch.

[0042] In step S4, the elevator call is transmitted to the elevator controller 15. The elevator call includes information about the floor to be taken (F1) and the target floor. The target floor is indicated by the floor indicator 28. The elevator operating device 6 transmits this information to the elevator controller 15 via the wired network 20, which then executes a dispatch algorithm to assign the elevator call to the elevator car 22. The dispatch algorithm used is known to those skilled in the art.

[0043] In step S5, the screen device 24 displays the elevator car 22 assigned to the elevator call. For this purpose, the elevator controller 15 can, for example, send dispatch information concerning the elevator car 22 to the control devices 40 and 42. The control devices 40 and 42 then accordingly manipulate the display device 24 to display elevator indicators (e.g., based on the dispatch information). Figure 2C and 2D (The "A" in the text). The elevator indicator is displayed for a predetermined duration, such as a few seconds (e.g., 1 to 2 seconds).

[0044] In one embodiment, from the perspective of users 4 and 5, the display of the elevator indicator occurs almost simultaneously with the confirmation of a registered elevator call. This is feasible because call dispatching is completed very quickly, for example, within milliseconds, using known dispatch algorithms. In one embodiment, confirmation of the elevator call can be visually perceived via screen device 24. Alternatively or additionally, this confirmation can also be made audibly, for example, by means of an electroacoustic transducer 52. The elevator operating device 6 then again displays the optical code 26.

[0045] The elevator control system terminates its operation for this elevator call according to... Figure 4 Step S6 is shown in the diagram. As those skilled in the art will know, after a call is assigned, the elevator controller 15 moves the elevator car 22 according to the elevator call 1 in order to transport users 4 and 5 to the desired target floor.

[0046] The following is a reference. Figure 5 Introduction for running Figure 1 An exemplary method of the elevator device 1 shown herein, the elevator device having the elevator operating device 6 shown therein. The method begins at step A1 and ends at step A9.

[0047] In step A2, display information is generated. The display information is generated by the elevator controller 15 and includes data to be encoded in optical encoding 26, which the elevator operating device 6 must display floor-specifically. This data may, for example, include the address (e.g., URL) of the elevator device 1, enabling the application (App) in the communication device 9 to communicate with the elevator device 1. The display information also includes data indicating the floor indicator 28 that the elevator operating device 6 must also display; in one embodiment, the floor indicator 28 may also be floor-specific. Additionally, the display information includes an identifier (number) for the display information. This display information is stored in the storage device of the elevator controller 15; thus, the storage device stores which display information, identifiable by the identifier, is sent to the designated elevator operating device 6 at what time.

[0048] In step A3, display information is sent from the elevator controller 15 to the elevator operating device 6. The elevator operating device 6 displays the optical code 26 and the floor indicator 28 based on this display information. An exemplary illustration of the optical code 26 and the floor indicator 28 is shown in... Figure 1 and Figure 2A As shown in the image.

[0049] In step A4, an elevator call is received. When the elevator controller 15 receives the elevator call, it also identifies which communication channel the elevator call was received via. If users 4 and 5 input the elevator call on the elevator operating device 6 via the touch display field 30, the communication channel includes the wired network 20. However, when user 5 uses the communication device 9, the communication channel includes an application programming (App) interface and / or a radio interface.

[0050] In step A5, the received elevator call is assigned to the elevator car 22 and assignment information is generated. As described above, the assignment algorithm is used for call assignment.

[0051] In step A6, it is determined whether the dispatch information needs to be sent to the elevator operating device 6 or to the communication device 9. In the illustrated embodiment, step A6 checks whether the elevator call has been completed via the surface of the touch screen device 24, and whether the elevator call has been transmitted from the relevant elevator operating device 6 via the wired network 20. If so, the method proceeds along the "yes" branch to step A7, in which the dispatch information is sent to the elevator operating device 6 via the wired network 20 (see [link to documentation]). Figure 4 Step S5 in the process.

[0052] Conversely, when user 5 uses communication device 9 to read optical code 26, an elevator call is received via the application interface. Therefore, the check in step A6 indicates that the elevator call was not generated by touching the elevator operating device 6, and the method proceeds along the "No" branch to step A8, where dispatch information is sent to user 5's communication device 9 via the application interface. The method ends at step A9.
