Description

Method for sending a user-specific message from a user device to an elevator system

The present invention relates to a method for sending a user-specific message from a user device to an elevator system. The invention further relates to a method for displaying a user-specific message via a display device of an elevator system as well as a data processing device, a computer program and a computer-readable medium for executing one or both methods. In addition, the invention relates to an elevator installation and an elevator system.

An elevator system, for example for transporting people and/or objects in buildings, is usually operated via car and/or floor panels. In addition, the control can be carried out contactlessly using a (mobile) user device such as a smartphone or tablet. For this purpose, a corresponding app can be installed on the user device. The functionality of such an app is usually limited to selecting a desired floor and sending a corresponding request to the elevator system via a wireless data communication connection.

There may be a need for a method that allows a user to display user-specific messages via a display device of the elevator system. Furthermore, there may be a need for a corresponding data processing device, a corresponding computer program, a corresponding computer-readable medium, a corresponding elevator system and a corresponding elevator system.

These needs can be met by the subject matter of the independent claims. Advantageous embodiments are set out in the dependent claims, the following description and the accompanying figures.

A first aspect of the invention relates to a method for sending a user-specific message from a user device to an elevator system, the elevator system comprising a display device and being connected to the user device via a data communication connection for data communication. The method includes: receiving input data that a user entered into the user device has, in a data processing device of the user device; Generating a user-specific message to be displayed via the display device from the input data; Sending the message to the elevator system via the data communication link to enable the message to be displayed via the display device.

The method may be computer-implemented and carried out automatically by a processor, for example the data processing device of the user device.

The user device can be a device that can be operated by a user and includes a computer, such as a server, a PC, a laptop, a tablet, a smartphone, a smartwatch or a remote control of the elevator system.

The data communication connection can be a wired and/or wireless data communication connection. For example, the data communication connection can be an Ethernet, WLAN, mobile phone, Bluetooth or Internet connection or a combination of at least two of these examples.

It is possible that one of several possible message contents, in particular with reference to the elevator system, is selected based on the input data and the message is generated with the selected message content. However, the message can also be generated with individual message content that includes at least part of the input data (e.g. a text formulated by the user). In other words, the message can also have any message content defined by the user. The respective message content can then be displayed via the display device.

The method enables remote control of the display device of the elevator system via the user device so that certain information selected by the user can be displayed to other users. This improves the exchange of information between users. For example, such information can help users to better plan elevator trips or to better estimate how long an elevator trip to a desired floor will take, which in turn improves user comfort.

A second aspect of the invention relates to a method for displaying a user-specific message via a display device of an elevator installation. The method comprises: receiving a user-specific message to be displayed via the display device in a data processing device of the elevator installation; displaying the message via the display device by controlling the display device, wherein the message was generated and/or is displayed using a user device of a user and wherein the user device is connected to the elevator installation via a data communication connection for data communication.

In other words, the message is only generated or displayed via the display device as a result of an interaction between the user and the user device and/or an interaction between the user device and the elevator system. Such an interaction can, for example, be an input of data to be displayed into the user device and/or a reception of data to be displayed via the data communication connection in the elevator system. However, such an interaction can also be a unique identification of the user by means of his user device to the elevator system and/or a detection of the user device (and thus the user) at (for example inside) or in the vicinity of an elevator car of the elevator car. In this case, certain data, for example the message itself, a unique user ID, a unique elevator ID or a combination of at least two of these examples, can be transmitted via the data communication connection.

The method can be computer-implemented and executed automatically by a processor, for example the data processing device of the elevator system.

A third aspect of the invention relates to a data processing device with a processor that is configured to carry out one or both of the methods described above and below. The data processing device can comprise hardware and/or software modules. In addition to the processor, the data processing device can comprise a memory and a data communication interface for wireless and/or wired data communication with peripheral devices. The data processing device can be, for example, a component of the user device and/or a component of a control device of the elevator system.

It should be noted that features of the methods as described above and below can also be features of the data processing device (and vice versa). A fourth aspect of the invention relates to an elevator system. The elevator system includes: an elevator shaft; an elevator car that can be moved in the elevator shaft between different floors of a building; a display device; the data processing device described above and below, wherein the processor of the data processing device is configured to carry out the method for displaying the message described above and below.

The display device can, for example, comprise a cabin display arranged inside the elevator cabin and/or a floor display arranged outside the elevator shaft in one of the floors for displaying the message. For example, the cabin display can be part of a cabin panel and/or the floor display can be part of a floor panel.

It is possible for the message to be displayed the same or differently on different displays of the display device. The different displays can differ from one another, for example in their size and/or position.

A fifth aspect of the invention relates to an elevator system. The elevator system comprises the elevator installation described above and below and one or more user devices, each user device comprising the data processing device described above and below. The processor of the data processing device is configured to carry out the method described above and below for sending the message.

Further aspects of the invention relate to a computer program and a computer-readable medium on which the computer program is stored.

The computer program includes instructions that, upon execution of the computer program by the processor, cause a processor to carry out one or both of the methods described above and below. The computer program can, for example, be special control software that runs on a control device of the elevator system and/or a special app that runs on the user device.

The computer-readable medium may be a volatile or non-volatile data storage device. For example, the computer-readable medium may include a hard drive, a USB (universal serial bus) storage device, a RAM (random-access memory), a ROM (read- only memory), an EPROM (erasable programmable read-only memory), an EEPROM (electrically erasable programmable read-only memory), a flash memory or a combination of at least two of these examples. The computer-readable medium can also be a data communications network that allows downloading of program code (e.g. via the Internet) or a cloud.

It is noted that features of the methods as described above and below may also be features of the computer program and/or the computer-readable medium (and vice versa).

Embodiments of the invention may be considered based on the ideas and findings described below. These embodiments should not be construed as limiting the scope of the invention.

According to one embodiment, the input data may include a desired display time at which the message is to be displayed, for example time, date, day of the week, calendar week, month or year.

Additionally or alternatively, the input data may include a desired display period during which the message is to be displayed, for example in seconds, minutes, hours, days, weeks, months or years.

Additionally or alternatively, the input data may include a desired repetition pattern according to which the display of the message is to be repeated, for example hourly, daily, weekly, monthly or at a user-defined frequency.

Additionally or alternatively, the input data can include a text formulated by the user (and to be displayed via the display device). However, the input data can also include audio and/or image data for playback via the display device, for example a voice and/or video message recorded by the user.

This input data can, for example, be entered via a special app running on the user device.

It is also conceivable that the message is sent and/or displayed depending on the user’s current location. The message can only be sent and/or displayed when the current location matches a desired location. The current and/or desired location may, for example, be part of the input data and/or sent to the elevator system via the data communication link. The current location may, for example, be determined in a digital map using a receiver for a global navigation satellite system (e.g. GPS, GLONASS, Galileo or Beidou) or other location sensor that may be part of or coupled to the user device.

According to one embodiment, the method for displaying the message may further include sending the message by performing the steps of the method for sending the message described above and below. In this case, features of the method for sending the message are to be understood as features of the method for displaying the message.

According to one embodiment, the method for displaying the message may further comprise the following steps: displaying an indication of an alternative floor to which the user could walk from a current floor via the display device by controlling the display device and/or by sending the indication via the data communication connection to the user device to enable the indication to be displayed via the user device, wherein the indication prompts the user to confirm the alternative floor. Once the confirmation is received, a signal transmitted by the user device is waited for for a certain waiting time, wherein the received signal indicates that the user has entered an elevator car of the elevator system located on the alternative floor. The message is only displayed if the signal is received within the waiting time.

In other words, using the user device, it can be detected whether a particular user has walked at least part of an elevator route. In this case, a corresponding message can be automatically displayed via the display device. By displaying the message, the user in question can, for example, be visually highlighted compared to other users (who did not walk), for example by being marked with a symbol as being particularly environmentally conscious.

The confirmation can be entered, for example, via a panel of the elevator system and/or via the user device. It is also conceivable that the user enters the confirmation via a panel of the elevator system and in response to this a Information regarding the alternative floor is sent to the user device (preferably via a wireless data communication link) so that the information, such as a name of the alternative floor and/or directions, can be accessed via the user device independently of the elevator system. This has the advantage that the user can conveniently view the information on the go via his user device.

The signal emitted by the user device may include a unique user identifier so that the user can be uniquely identified using the signal. For example, the user device may be equipped with an active or passive (RFID) transponder for emitting the signal and/or configured to emit the signal with a range of at most 10 meters, preferably at most 1 meter. The signal can be sent out automatically, for example in response to confirmation of the alternative floor, or as a result of additional input from the user, i.e. triggered by the user using the user device.

The lift system can be equipped with one or more receiving devices for receiving the signal. Such a receiving device (also called a reader) can be arranged, for example, on or inside the lift car or near a door area through which the lift car is accessible to users of the lift system from a floor (see below).

It is also possible that, conversely, the user device includes a reading device and the receiving device of the elevator system is an active or passive (RFID) transponder.

This enables contactless identification and/or localization of the user via his user device.

Another possible variant is that the user sends a user-specific message to the elevator system, the message is stored there, but is only displayed on the display device when the signal is received within the waiting time, i.e. when it is recognized (in time) that the user has walked part of an elevator route.

According to one embodiment, the signal can be received via a receiving device that is arranged on (for example within) or near the elevator car. Such a receiving device can be a transmitter and/or receiver for wireless Data communication, for example via Bluetooth and/or in an RFID process. The receiving device can be a component of the data processing device of the elevator system or can be connected to the data processing device of the elevator system for data communication.

According to one embodiment, at least one of the following information can be displayed by displaying the message:

- input data that the user has entered into the user device (for example, as mentioned above, a text formulated by the user);

- a user identifier to uniquely identify the user (e.g. their name, their initials, their pseudonym, their photo, their avatar, a unique character string or a combination of at least two of these examples);

- a symbol that (additionally) distinguishes the user, or more precisely his or her displayed user ID, from other users, or more precisely from their displayed user IDs;

- a floor desired by the user at which the elevator system should stop;

- a lift desired by the user from several possible lifts in the lift system.

At least one of the information user ID, symbol, desired floor and desired elevator can be part of the input data, i.e. entered into the user device by the user.

The symbol can be, for example, a pictogram, an image, text or a combination of at least two of these examples. For example, the symbol can identify the user as being particularly environmentally conscious or generally as a user who is particularly worthy of emulation (with regard to their usage behavior). The symbol can be displayed in particular (for example next to a user ID assigned to the user) if the user has walked part of an elevator route and is to be highlighted compared to other users who have not walked (see also above).

If the user is a building manager, he or she can send a corresponding user-specific message to the elevator system, for example, information regarding the current status of the elevator system (e.g. "maintenance", "repair" or "cleaning"), regarding the current operating mode of the elevator system (e.g. "energy saving mode active" or "silent mode active") or with regard to certain types of users transported by the lift system (e.g. ‘lift personnel’ or ‘wheelchair users’).

It is possible that a priority is additionally determined for the message and the message is received and/or displayed according to its priority. This allows higher priority messages to be prioritized over lower priority messages.

The priority can be determined, for example, using a user ID assigned to the message. In other words, messages from different users can differ from one another in terms of their priority, among other things. For example, a message from a building manager (see above) can generally have a higher priority than a message from a normal elevator passenger.

According to one embodiment, the message can be received via the data communication connection in the data processing device of the elevator system. This enables the message to be generated independently of and/or outside the elevator system.

According to one embodiment, the desired floor from the message can be displayed differently than if the desired floor is entered via a panel of the elevator system and displayed via the display device. This allows visual differentiation of the desired floors displayed depending on whether they were entered via a user device or a panel. For example, in cases where multiple users are waiting in front of one or more elevators of the elevator system to go to the same floor, it can be confusing if the floor is displayed the same for each user. For example, a user who has requested a floor via his user device does not know in such a case whether the displayed floor was requested via the panel by himself or by another user who was also waiting.

According to one embodiment, at least one second user device can be connected to the user device and/or the elevator system via the data communication connection for data communication. In this case, the method may further include sending the message over the data communication link to the second user device or devices to enable the message to be additionally displayed via the second user device or devices. This means the message can be displayed to users regardless of their location. In other words, the message can therefore also be displayed to users who are not in the vicinity of the display device, that is, the users do not necessarily have to be in the vicinity of the display device in order to be informed of the message.

Embodiments of the invention are described below with reference to the accompanying drawings. Neither the description nor the drawings should be construed as limiting the scope of the invention.

Fig. 1 shows an elevator system according to an embodiment of the invention.

Fig. 2 shows a display device of an elevator installation according to an embodiment of the invention.

The drawings are purely schematic and not to scale. If the same reference symbols are used in different drawings, these reference symbols indicate the same or equivalent features.

Fig. 1 shows an elevator system 1 that includes an elevator system 3 and a user device 5, here a smartphone. The user device 5 can also be a PC, a laptop, a tablet, a smartwatch or a specially developed remote control. The elevator system 1 can also include two (as here) or more than two user devices 5.

The elevator system 3 includes an elevator shaft 7, in which an elevator car 9 (hereinafter referred to as car 9 for short) can be moved between several floors 10 of a building 11 by means of an electric drive 13. In addition, the elevator system 3 includes a control device 14 for controlling components of the elevator system 3, for example the electric drive 13, depending on the desired floors at which the car 9 is to stop, and a display device 15 (see FIG. 2), on which certain for users the elevator system 3 relevant information can be displayed.

As shown in Fig. 2, the display device 15 can include several displays, for example a cabin display 15a, which can be arranged within the cabin 9, and / or a floor display 15b, which is next to or above a door area through which the cabin 9 can be accessed from one Floor 10 is accessible to the users, can be arranged. Each of the devices 5, 14 includes a data processing device 17 with a memory 19 on which a special computer program is stored, a processor 21 which is configured to execute the computer program, and a data communication interface 23. The data communication interface 23 of the user device 5 is connected to the Data communication interface 23 of the control device 14 is connected via a data communication connection 25 for data communication, here for wireless data communication, for example via WLAN, mobile radio, Bluetooth and / or the Internet. However, a wired data communication connection 25 is also possible. The data communication between the devices 5, 14 can take place directly or indirectly, for example via at least one server and/or at least one other user device.

By the processor 21 of the user device 5 executing the computer program stored in the memory 19 of the user device 5, the following steps of a method for sending a user-specific message to the elevator system 3 can be carried out.

In a first step, input data 27 that a user has entered into the user device 5, here for example via a touch display of the smartphone in a special elevator app running on the smartphone, are received in the data processing device 17 of the user device 5.

The input data 27 includes, on the one hand, information that is to be displayed via the display device 15, for example a text formulated by the user, a voice message recorded by the user, a video message recorded by the user or a combination of at least two of these examples. Such information may also include a user ID to uniquely identify the user (e.g. their name, their initials, their pseudonym, their photo, their avatar, a unique character string or a combination of at least two of these examples), a floor desired by the user or a location requested by the user The user's desired elevator can be one of several possible elevators in the elevator system 3.

In addition, the input data 27 can define, ie the user can define by entering corresponding input data 27 when and/or how long and/or according to which repetition pattern this information should be displayed. In a second step, a user-specific message 29 is generated from the input data 27, which is to be displayed via the display device 15. The content of the message 29 to be displayed can correspond to the input data 27 or at least a part thereof.

In a third step, the message 29 is finally sent to the data processing device 17 of the control device 14 via the data communication connection 25 in order to enable the message 29 to be displayed via the display device 15.

Additionally, the user device 5 may send the message 29 to at least one second user device 5 to enable the message 29 to also be displayed via the second user device 5.

By the processor 21 of the control unit 14 executing the computer program stored in the memory 19 of the control unit 14, the following steps of a method for displaying a user-specific message 29 via the display device 15 can be carried out.

In a first step, the message 29 is received in the data processing device 17 of the control unit 14. For example, the message 29 can be read from the memory 19 of the control unit 14. However, the message 29 can also be received, as here, via the data communication connection 25, i.e. from the user device 5. In this case, the message 29 can have been sent by carrying out the steps of the sending method described above.

In a second step, the control unit 14 generates a control command 30 which causes the message 29 to be displayed via the display device 15, for example in accordance with the aforementioned display parameters such as display time, display duration and repetition pattern.

In general, in order to generate and/or display the message 29, at least one interaction of the user device 5 with the user (see above) and/or with the control device 14 (see below) is required. It is possible, for example, for the message 29 to be displayed depending on whether the user is walking at least part of an elevator route between two floors 10, which are connected to one another via a staircase, or is covering the entire elevator route in the car 9.

In this case, for example, an indication of an alternative floor to which the user could walk from a current floor can be displayed by the control device 14 controlling the display device 15 so that the indication is displayed via the display device 15, and / or sends the notice via the data communication connection 25 to the user device 5 in order to enable the notice to be displayed via the user device 5, here for example via the touch display of the smartphone in the elevator app.

The notice may also ask the user to confirm the displayed alternative floor in a specific way. The confirmation can be entered, for example, via a control element of a panel of the elevator system 3 and/or via the user device 5 (for example by touching a corresponding control panel on a touch display of the panel or the user device 5).

In both cases, the confirmation can be received in the data processing device 17 of the control device 14 and further processed there.

Receiving the confirmation can trigger a timer. If a signal 31 emitted by the user device 5 is received in the control device 14 within a certain waiting time since the confirmation was received, for example via a receiving device 33 in the form of an RFID reader which is placed in a cabin 9 located on the alternative floor, the message is 29 displayed. Otherwise, i.e. i.e., if signal 31 is not received or is only received after the waiting time has expired, message 29 is not displayed.

By displaying the message 29, the user in question who has walked can be distinguished from other users who may not have walked (more precisely from the displayed user IDs of these users) as a particularly environmentally friendly and/or exemplary user, for example with a specific symbol next to his user ID, which is also displayed. In addition, by displaying the message 29, information regarding a length of the elevator route covered on foot and/or an associated (estimated) energy saving can be displayed. The waiting time can be constant, ie set to a specific value such as 5, 10 or 15 minutes. However, it is also possible for the waiting time to vary, for example depending on the length of the elevator route to be covered on foot and/or the current capacity of the elevator system 3. The longer the elevator route to be covered on foot and/or the greater the capacity of the elevator system 3, the longer the waiting time can be selected to be (ie the longer the user, when he has arrived at the alternative floor, may have to wait for a cabin 9 in order to cover the rest of the elevator route in the cabin 9).

If the message 29 includes a desired floor, as mentioned above, it is possible that the control device 14 controls the display device 15 to display the desired floor from the message 29 differently than if the same floor is to be entered in the usual way via a panel of the elevator system 3 and displayed as the desired floor via the display device 15.

If, for example, a first user waiting in front of a first elevator of the elevator system 3 requests a floor via his user device 5, while a second user waiting in front of a second elevator of the elevator system 3 requests the same floor via the panel, a display device 15 of the first elevator can display not only the name of the desired floor but also a first symbol assigned to the user device 5, and a display device 15 of the second elevator can display not only the name of the desired floor but also a second symbol that differs from the first symbol and is assigned to the panel. This allows users to clearly assign the desired floors displayed, even if their names are the same.

It is possible for the control device 14 to additionally forward the message 29 to at least a second user device 5 in order to enable the message 29 to also be displayed via the second user device 5.

Finally, it should be noted that terms such as “comprise”, “comprise”, “include”, “with”, etc. do not exclude other elements or steps and indefinite articles such as “a” or “an” do not exclude a plurality. It is further noted that features or steps described with reference to one of the above embodiments may also be used in combination with features or steps described with reference to other of the above embodiments. Reference numerals are in the claims should not be construed as limiting the scope of the subject matter defined by the claims.
