Description

The technology described here generally relates to an elevator system. Embodiments of the technology relate in particular to an elevator operating terminal and an elevator system with such an elevator operating terminal. Embodiments of the technology also relate to a method for operating the call entry terminal.

In known elevator systems, a passenger can enter an elevator call at an elevator operating device, hereinafter referred to as an elevator operating terminal. An elevator operating terminal can be arranged on a floor of a building in order to enable a floor call to be entered from there. Depending on the control technology used in an elevator system, different types of elevator control terminals are used. An elevator operating terminal for an elevator system with an up/down direction control only allows the desired direction of travel to be entered as a floor call with a button for the up direction and a button for the down direction. In such an elevator system, an elevator operating terminal in an elevator car enables the entry of a car call with which a passenger indicates the desired destination floor, for example by pressing a button assigned to the destination floor. An elevator operating terminal for an elevator system with a destination call control enables the desired destination floor to be entered as a floor call, for example by pressing a button assigned to the destination floor. It is then usually no longer possible to enter a call in the elevator car.

Particularly in very tall buildings with a correspondingly large number of floors, a large number of keys with a correspondingly high space requirement may be required in order to enable the entry of all possible target floors. As an alternative to such buttons is out EP 0 699 617 B1 a call entry terminal is known that has a reader for an RFID card presented by a user for call entry. However, such reading devices and the management of RFID cards are not suitable for all buildings because, for example, B. require a relatively high level of effort in terms of costs and administration. Another alternative is out US 2014/0014444 known, in which an elevator operating terminal arranged on a floor only shows a few floors on a display in the form of a line that the user can touch to enter a call. If the user swipes anywhere on the display, other floors are displayed. Floors that have already been selected will no longer be displayed in the list.

EP 3 318 523 A1 discloses an elevator operator terminal that displays a list of floor pairs resulting from recent elevator rides. A start floor and a target floor each form a floor pair. A user can use the list displayed on a touch-sensitive screen to enter new elevator calls. By touching a field indicating the start floor field or destination floor, the user can select a different start or destination floor to set the start and destination for the new elevator call. EP 3 318 523 A1 discloses the preamble of claim 1. EP 3 345 853 A1 discloses a similar elevator control terminal; the list displayed is referred to as the suggestion list.

EP 3 015 412 A1 discloses an elevator operating terminal with a touchscreen for entering an elevator call. The touchscreen shows floors arranged in the correct position, one above the other. Floors not shown can be reached by scrolling. Scrolling on the touchscreen can be triggered by swiping gestures in the respective scrolling direction.

Although these alternatives reveal certain solutions to the high button count problem, there is a need for an elevator control terminal technology that is usable and user-friendly in a variety of buildings.

One aspect of the invention described here relates to an elevator operating terminal for an elevator system according to claim 1.

Another aspect relates to an elevator system according to claim 9.

Another aspect of the invention relates to a method for operating an elevator operating terminal according to claim 10.

In an elevator operating terminal according to the technology described here, the user interface includes a call input area and at least one floor display area. The call input area shows the display fields that are enabled for call input, while the floor display area shows the display fields on which no call input is (currently) possible; these display fields are deactivated or blocked. The area in which a call can be entered is therefore fixed. This has the advantage that the elevator control terminal can be arranged (with the call input area as a reference point) so that the call input area is in a prescribed height range (e.g. at a distance of 900 mm to 1200 mm from the floor), independently on the number of display fields displayed in the floor display area. The display fields displayed on the user interface away from the call input area can be used for information purposes, but need to be touched.

Depending on the number of floors, all or a majority of the floors are displayed on the user interface. This allows flexibility in configuring the elevator terminal for a building in deciding how many floors to display in addition to those in the call entry area, without potentially causing users to lose track. If not only the display fields currently released for call input are displayed, but also others in the floor display area, it can be easier for a user to better orientate themselves in the building with regard to the floors.

According to the invention, the processing device is designed to confirm an entered call for a travel request to a destination floor by marking the display field corresponding to the destination floor. The marking can be done through a perceptible choice of color and/or pattern (e.g. using (background) lighting). The user receives confirmation that the call has been registered. In addition, the marked display field remains marked until the call has been answered. This informs other users which calls have already been made and on which floors the elevator car stops.

According to the invention, the processing device is designed so that if several calls are entered for travel requests to different destination floors, each call is confirmed by marking the display field corresponding to the respective destination floor; The respective marked display field can be assigned to the call input area or the floor display area. This can z. B. a new user can quickly recognize which floor or floors that are displayed in the call input area have already been made, so that there is no need to enter the call again.

In one exemplary embodiment, the processing device is designed to generate a display field for a convenience function on the user interface, which is separated from the call input area and floor display area. The processing device is designed to register a call input for a request to travel to a special floor when the comfort function is used by a user. For this comfort function, a frequently desired floor, e.g. B. an entrance hall, can be specified as a special floor. Depicted as detached Display field it is clearly visible to a user.

In one exemplary embodiment, the aforementioned displaceability of display fields from the floor display area into the call input area takes place by means of a display field for a displacement function, which is shown on the user interface. The processing device is designed to replace the display fields shown in the call input area with a corresponding number of display fields from the floor display area when a user uses the shifting function. This allows a user to "scroll" through the selectable floors until the desired target floor is displayed in the call input area. The display field for the shifting function is arranged at the level of the call input area, which results in the advantages mentioned with regard to the height arrangement.

In one embodiment, a sum of the first number of display fields and the second number of display fields is smaller than the specified number of floors of the building, so that fewer floors are represented than can be operated by the elevator system in the building. This is particularly advantageous in buildings with many floors and not all floors have space in the usual size on the user interface. For example, if a user uses the panning function, they can "scroll" until the top or bottom floor served by the elevator system is displayed. With the technology described here, the user is made aware that there may still be “many” hidden floors that can be moved to the call input area by “scrolling”.

In one exemplary embodiment, the processing device is designed to display the display fields of the floor display area and the display fields of the call input area arranged line by line on the user interface. The display fields of the floor display area are arranged in several lines. Such a representation in the form of a matrix makes it easier for a user to operate the elevator operating terminal.

In one exemplary embodiment, the processing device is designed to display the display fields in the call input area larger than the display fields in the floor display area. This also contributes to simplifying operation and thus user-friendliness.

In addition to simplifying the operation of the elevator control terminal, the technology described here also enables the use of the building and orientation in the building to be optimized. In one exemplary embodiment, the processing device is designed to display a pictogram that can be activated by a user in a display field shown in the call input area. When the pictogram is activated in the call input area, floor-specific information is displayed.

Fig. 1 shows a schematic representation of an exemplary embodiment of an elevator system 1 in a building; In principle, the building can be any type of multi-story building (e.g. residential building, hotel, office building, sports facility, etc.), with the technology described here being particularly advantageous in very tall buildings, for example in buildings with more than 1,000 m 20 floors. Components and functions of the elevator system 1 are explained below insofar as they appear helpful for an understanding of the technology described here. This in Fig. 1 Building shown has a plurality of floors L1, L2, L3, which are served by the elevator system 1, that is, a passenger 8 can go Entering a call at an elevator operating terminal 2, 4 can be transported by the elevator system 1 from an boarding floor to a destination floor.

In the exemplary embodiment shown, the elevator system 1 has an elevator car 6, which can be moved along a roadway in the building. The roadway extends, for example, along a vertical elevator shaft 10. In another embodiment, the roadway may extend along a horizontal or inclined plane. In a further exemplary embodiment, the roadway can have vertical and horizontal sections. The technology disclosed here is described below based on the in Fig. 1 exemplary elevator system 1 shown.

This in Fig. 1 Elevator system 1 shown also includes an elevator control (EC) 12, a drive machine (M) 14, a counterweight 18, a transmission device 20, a suspension element 16 (one or more steel cables or flat belts) and several deflection rollers 24. The suspension element 16 has two ends, each end being attached to a fixed point 22 in the elevator shaft 10. Between the fixed points 22, the suspension element 16 partially wraps around the deflection roller 24 on the counterweight 18, a traction sheave of the drive machine 14 and the deflection rollers 24 on the elevator car 6. The elevator system 1 shown is therefore a traction elevator, with further details, such as guide rails for the elevator car 6 and guide rails for the counterweight 18 in Fig. 1 are not shown. The elevator control 12 is connected to the drive machine 14 and controls it in order to move the elevator car 6 in the shaft 10. The function of a traction elevator, its components and the tasks of an elevator control 12 are generally known to those skilled in the art. One skilled in the art will recognize that the technology described is not limited to use in a traction elevator. The person skilled in the art will also recognize that the elevator system 1 may include multiple elevator cars 6 or multiple cars in one or more elevator shafts 10, or may include one or more groups of elevators controlled by a group controller.

In Fig. 1 An elevator operating terminal 4 (also referred to as terminal 4) is arranged on each floor L1, L2, L3 and is coupled to the elevator control 12 by means of a communication connection 26. The communication connection 26 can be wired (e.g. through individual lines or a communication bus). and/or implemented wirelessly. Each of these elevator operating terminals 4 can z. B. have a terminal identifier (also referred to as a terminal ID) through which a terminal 4 can be identified and addressed; For example, the terminal 4 sends a call together with its terminal ID to the elevator control 12, which confirms the call to the terminal 4 identified by the terminal ID. Information about an assigned elevator can also be sent.

Another elevator operating terminal 2 is in Fig. 1 arranged in the elevator car 6 and connected to the elevator control 12 by means of the transmission device 20. For better differentiation, the floor-side elevator operating terminal 4 can be referred to as floor terminal 4 and the car-side elevator operating terminal 2 as car terminal 2. For illustration, the elevator operating terminals 2, 4 are shown with the same symbol. The person skilled in the art will recognize that, for example, the floor terminal 4 can only be designed to enter a desired direction of travel, that is, it has a button for the upward direction and a button for the downward direction, while the cabin terminal 2 enables the entry of a destination floor.

The floor terminal 4 can be arranged at a desired location on a floor L1, L2, L3, e.g. B. on a building wall or free-standing in a desired location. As a place can e.g. B. an anteroom in front of one or more elevator (floor) doors or access to an elevator hall can be provided. While the location can be chosen relatively freely, there are specifications (e.g. according to a standard or legal type) as to the height range in which the floor terminal 4 or a user interface of the floor terminal 4 is to be arranged. This is intended to ensure that the floor terminal 4 is at a height at which the floor terminal 4 or the user interface can be reached by potential users and displayed information can be perceived. Examples of potential users include standing users (adults and children, with or without hand/arm mobility restrictions) and seated users (e.g. in a wheelchair). An exemplary standard (EN81-70) specifies the height range between 900 mm and 1200 mm. Corresponding requirements could also exist for the arrangement of the cabin terminal 2.

In one exemplary embodiment, the transmission device 20 comprises an electrical cable which, for. B. is provided in a traction elevator for the transmission of electrical energy and electrical signals and extends between the elevator car 6 and a fixed point to which the elevator control 12 is coupled. The electric cable has electrical energy and signal lines for this purpose. The electric cable, for example, supplies the elevator car 6 with electrical energy and transmits signals (e.g. load, status and/or car call information) from and to the elevator car 6. The electric cable is also known to a person skilled in the art as a (flat) hanging cable, hereinafter it is therefore referred to as such. The person skilled in the art is therefore aware of devices which couple the hanging cable on the one hand to the elevator control 12 and its power/voltage supply and on the other hand to the elevator car 6 and its electrical and electronic components. The person skilled in the art will recognize that the cabin terminal 2 is electrically coupled to the hanging cable.

Fig. 2 shows a schematic representation of an exemplary embodiment of an elevator operating terminal 2, 4, which has a processing device 32 (µP), a memory device 52 and a display device 34. In one exemplary embodiment, the storage device 52 stores a computer program that the processing device 32 executes during operation. The processing device 32 controls the display device 34, as described below; it is also equipped with the elevator control 12, which is in Fig. 2 shown with dashed lines for illustration, communicatively connected.

The display device 34 includes a touch-sensitive screen, which is referred to below as a touchscreen. The functionality and structure of a touchscreen are generally known to the person skilled in the art, in particular it is known to the person skilled in the art, for example from the programming and use of smartphones, how symbols, pictograms, input and output fields, etc. are generated on a touchscreen and displayed on the user interface. It is also known to those skilled in the art that the components of the elevator operating terminal 2, 4 can be arranged, for example, in a housing, so that the elevator operating terminal 2, 4 can be arranged at the desired location in the elevator car 6 or on a floor L1, L2, L3.

Controlled by the processing device 32, the display device 34 displays a user interface 38 depending on the situation prevailing in the elevator system 1. Using this user interface 38, a user can, for example, enter a call and receive information about the prevailing situation, for example about calls made and confirmed. In addition to this user interface 38, in one embodiment the terminal 2, 4 has a loudspeaker (not shown) for outputting acoustic messages.

Im in Fig. 2 In the illustrated embodiment, the user interface 38 displays a current screen content; the screen content can also be referred to as window content. The expert recognizes that the screen content (window content) can change when operated by a user, for example after a call is entered. The exemplary user interface 38 displays a variety of fields 36, 40, 42, only some of which are provided with reference numbers for purposes of illustration. The fields 40 are numbered and arranged line by line, in the example shown here, in three columns, ie three fields 40 are arranged in each line. Each of these fields 40 corresponds to a floor that can be served by the pull-out system 1. In this exemplary embodiment, the fields 40 for floors -1 to 25 are shown legibly, with it being illustrated that further floors above floor 25 can be reached with the elevator system 1, this is in Fig. 2 indicated by the top two lines, in which the fields 40 in the spatial representation are already too small to display numbers clearly. Some of the fields 40 shown are marked; these are marked as fields 40.1, 40.2, 40.3. The fields 40 are referred to below as display fields 40.

In the in Fig. 2 In the situation shown, the display fields 40 for the floors 11, 12, 13 are arranged in an area around an axis 50; these are shown enlarged and can be selected by the user; this area is referred to below as the call input area 46.

In order to be able to display other display fields 40 for floor selection, the user can operate the field 36 in one exemplary embodiment. The field 36 represents a functionality that allows the user to change part of the screen content by essentially "scrolling" through the floors. From the user's perspective, it can for example, scrolling up or down; If the user swipes a finger downwards, display fields 40 for higher floors are shown enlarged line by line (or they move increasingly from the background into the foreground); if, on the other hand, he swipes his finger upwards, display fields increase in size line by line 40 shown enlarged for lower floors. In Fig. 2 This functionality is indicated by a double arrow 48. Such a scrolling or moving functionality is similar to a “scroll” function known from computer technology. In another exemplary embodiment, the functionality of the field 36 can also be extended to a larger area of the user interface 38, for example to the entire area. In this case, a user's swipe movement can occur over a larger area, which may make operation easier because it may be more intuitive for some users.

Those skilled in the art will recognize that in another embodiment, the user interface 38 may display the display fields 40 and the input area 46 in a different arrangement, for example with one, two, four or more columns. The input area 46 can, for example, extend perpendicular to the axis 50 and can include one, two or more than three display fields 40. In addition, the display fields 40 can be displayed more or less overlapping in order to intuitively represent spatiality or movability. Because of the desired representation of a space in one exemplary embodiment, the display fields 40 in the area around the axis 50 are shown larger than the other display fields 40 (they appear in the foreground, so to speak), with the other display fields 40 being shown smaller the further they are from the axis 50 away (they appear in the background or are not shown because, for example, the number of floors is too high).

In one embodiment, the display fields 40 may be highlighted as soon as they are moved into the call input area 46. Such highlighting can e.g. B. by the color and / or brightness of the display fields 40 and / or the shape of the display fields 40. This means that no user is signaled that these display fields 40 are now in the selectable area.

The remaining display fields 40 mentioned, ie those which are displayed outside the call input area 46, are displayed in a floor display area 54, 56. In Fig. 2 Two floor display areas 54, 56 are shown by way of example, one (54) below the call input area 46 and one above (56) of the call input area 46. Each of these display fields 40 is assigned a fixed floor L1, L2, L3. As stated elsewhere in this description, no call input is possible on the display fields 40 of the floor display area 54, 56; They serve, for example, to inform a user and/or for their orientation.

In Fig. 2 the display fields 40 show the floors assigned to them in consecutive (ascending) numbering. In another exemplary embodiment, the display fields 40 only show the floors that are accessed most frequently. This can then e.g. B. may be desired with a very large number of floors and limited screen space in order to make operation easier. The display fields 40 of the most frequently visited floors can be marked and/or enlarged.

In one embodiment, the user interface 38 shows the in Fig. 2 Field 42 shown is displayed regardless of the situation, in particular the field 42 is displayed independently of any scrolling by the user. In one embodiment, the user interface 38 continuously displays the field 42 during operation. The field 42 shown is in Fig. 2 assigned to a floor on which there is a building entrance and/or an entrance hall, this is illustrated by the number "0"; that a user on this floor can leave the building is illustrated by an arrow 44 in conjunction with a symbol for a person walking. A frequently chosen floor such as B. the entrance hall floor therefore does not require "scrolling", making it easier to use, including for visitors who may not be familiar with the building. As such, the field 42 enables a convenience function that allows convenient call entry. One skilled in the art will recognize that in another embodiment, more than one field 42 may be present for a convenience function.

In Fig. 2 It can also be seen that an information symbol 58 is shown in or near a display field 40 that is assigned to the 13th floor. The user can touch the information symbol 58 to access information stored for this floor receive. The information can be displayed to the user, which is in Fig. 3 is indicated by an information field 60. Depending on the type of building, the information may include business information (e.g. names of companies or service providers (e.g. law firms or medical practices)) or private information (e.g. names of residents). Additionally or alternatively, the information can also be issued as a voice message. The person skilled in the art will recognize that further display fields 40 in the call input area 46 can each have such an information symbol.

This in Fig. 3 In the exemplary embodiment shown, the information field 60 shown includes an information field 62, by means of which the user can obtain more detailed information. To illustrate, the information field concerns in Fig. 3 a cafeteria. The more detailed information that can be accessed by touching the information field 62 can e.g. B. display the opening times, contact information and/or the menu of the cafeteria. The more detailed information can additionally or alternatively display an optical code, e.g. B. QR Code. By touching a symbol 64, the information field 60 can be closed. In another exemplary embodiment, the information field 60 is closed when the elevator call (here: floor 13) is made; For example, the information field 60 can confirm to a user that the correct floor has been found.

In Fig. 3 The information field 62 extends along the call input area 46 and covers the in Fig. 2 Display fields 40 shown for floors 11 and 12. The person skilled in the art will recognize that the information field 62 can be displayed in a different way, e.g. B. in a different orientation (e.g. vertical) or in the form of a speech bubble, which leads from the display field 40 for the floor 13 into an area of the user interface 38, which may block fewer display fields 40.

With the understanding of the basic system components of the elevator system 1 described above and its functionalities, the following is based on Fig. 4 a description of an exemplary method for operating an elevator operating terminal 2 arranged in the elevator system 1. The description is made with reference to an elevator operating terminal 2, which is arranged in the elevator car 6. The elevator system 1 is in operation (ie not in standby mode). This in Fig. 4 The method shown begins in a step S1 and ends in a step S7. The expert recognizes that the division into the steps shown is exemplary and that one or more of these steps can be divided into one or more sub-steps or that several of the steps can be combined into one step, within the scope of protection of the appended claims,

The elevator operating device 2 is activated and its processing device 32 controls the display device 34. The control creates a user interface 38, which is displayed by the display device 34. The generated user interface 38 includes a variety of display fields. In Fig. 4 this takes place in a step S2.

In a step S3, a call input area 46 is generated on the user interface 38. The call input area 46 includes a first number of display fields 40, each of which is assigned to a specified floor L1, L2, L3. In Fig. 2 these are floors 11, 12 and 13.

In a step S4, the display fields 40 in the call input area 46 are enabled for a call input. This means that a user can touch a display field 40 shown in the call input area 46 in order to enter an elevator call to the floor assigned to the display field 40.

In a step S5, a floor display area 54, 56 is generated on the user interface 38. The floor display area 54, 56 includes a second number of display fields 40, each of which is assigned to a specified floor L1, L2, L3. In Fig. 2 Two floor display areas 54, 56 are shown as an example: The floor display area 54 concerns the floors (here: floors -1 to 10) that lie below the floors displayed in the call input area 46 (here: floors 11 to 13), and the floor display area 56 concerns the floors (here: floors 16 to "top floor"), which are above the floors displayed in the call input area 46 (here: floors 11, 12 and 13).

In a step S6, the display fields 40 in the floor display area 54, 56 are blocked for call input. This means that a user can see a display field 40 shown in the floor display area 54, 56, but a call input is not possible using the display fields 40 in the floor display area 54, 56.

The person skilled in the art will recognize that the processing device 32 of the elevator operating terminal 2 dynamically adapts the user interface 38 to the situation prevailing in the elevator system 1. Each of the in Fig. 2 and Fig. 3 The situations shown represent a current situation, which is caused by e.g. B. can change a user action. For example, an action by a user results in the in Fig. 3 situation shown as an example, which comes from the in Fig. 2 situation shown.

In the Fig. 2 and Fig. 3 User interfaces 38 shown as examples show situations in which users have already entered several calls. Accordingly, the user interface 38 displays the confirmed calls. In Figs. 2 and 3 These are, for example, calls to floors 17, 12 and 5; the display fields 40.1, 40.2 and 40.3 are marked accordingly. The display fields 40.1, 40.2, 40.3 can, for example, be illuminated completely or partially (e.g. only one frame), with no color accentuation. The user thus recognizes, for example, which floors the elevator car 6 travels to.

Among the confirmed calls there may be a call that a user has entered on a floor. If the elevator operating terminal 2 is arranged in the elevator car 6, the user interface 38 can, in one exemplary embodiment, identify this floor call by a special marking (e.g. using color). Users in the elevator car 6 can therefore prepare for another user to board, for example by releasing the door area, thereby avoiding possible delays.

In one exemplary embodiment, the boarding user in the elevator car 6 can enter a car call to the desired destination floor. Depending on the situation, the desired destination floor can already be assigned to a display field 40 shown in the call input area 46, which the user can touch to enter the call. These display fields 40 are highlighted by their size and are easily recognizable to the user. If the desired destination floor is not in the call input area 46, the user can use the field 36 (or a larger area on the user interface 38, as described above) to move higher or lower "Browse" the floors until the target floor appears in the call input area 46. Alternatively, the user can touch the field 42 for the convenience function mentioned above.

For the exemplary description of the process according to Fig. 4 the elevator operating terminal 2 is arranged in the elevator car 6. Those skilled in the art will recognize that the technology described herein is not limited to this application; it can be used in the elevator system 1 both on a floor L1, L2, L2 and in the elevator car 6. If the technology is used on the floor, the elevator operating terminal 4 is designed, for example, to enter destination calls. The target floor is selected as described above.

Regardless of whether the elevator operating terminal 2, 4 is arranged on a floor L1, L2, L3 or in the elevator car 6, the technology described here offers the advantage that the call can be entered at a height in the height range between 900 mm and 1200 mm (e.g. according to EN81-70). This is the case with the technology described here, among other things. guaranteed even if there are a lot of floors. Through the implemented scroll function, in particular by means of the field 36, a user can also use the display fields 40 for (from the user's perspective) "far away" floors (which may either be relatively small or not yet displayed on the user interface 38 are) into the call input area 46.
