Description

Technical Field

[0001] The present invention relates to a travel path device having a drive unit, a surrounding handrail, a control unit, a measuring device, two boarding and alighting areas, and a step or pallet guided around them, wherein the measuring device includes at least one sensor unit for measuring at least one operating parameter of the travel path device, and wherein the control unit is configured to output at least one control command as a function of time based on an instantaneous measurement signal or measured value of the measuring device relating to the at least one operating parameter. The present invention particularly relates to a travel path device designed as an escalator or a moving walkway. In addition, the present invention relates to a method for providing visually perceptible information in such a travel path device, in particular an escalator or a moving walkway. The present invention also relates to the use of a columnar optical display unit for providing information in such a travel path device at a relative position that is advantageous to the respective user. The present invention particularly relates to a device and a method according to the preambles of the respective independent claims. Background Art

[0002] When using a travel path device, the user is often in a busy situation in which instantaneous, current, situation-specific, or location-dependent information is useful. For example, the user is on a journey and / or needs to complete shopping. The user may be lost in thought, trying to find their way, or must try to catch up on travel time or effectively arrange other appointments or matters. This results in the user not always being particularly focused when using the travel path device; the user may even be busy operating a smartphone. This also involves, in particular, safety risks that may also be critical for the organization operating the travel path device. In this regard, it is necessary to improve the user's attention when using escalators, in particular to more easily remind them of the safety-related factors that may be involved when using the corresponding travel path device, and to be able to provide targeted prompts to the user based on the user's current specific situation.

[0003] For example, optical display elements can be used to display the operating status or the direction of movement of a circular staircase, for example, on an escalator. Based on such elements, for example in the form of entrance signs and / or colored illuminated display elements, the need for improved information provision can be seen.

[0004] Publication EP 3 875 419 A1 describes an escalator having a column arranged in the boarding and alighting area, on which information about the desired or recommended use of the left and right travel channels of the escalator (walking or staying) is played to the users, in particular in order to achieve the highest possible transport capacity and ensure that user groups with different mobility abilities can use the escalator smoothly, in particular following the principle of "standing on the right, walking on the left". Summary of the Invention

[0005] The object of the present invention is to provide a travel path device and a corresponding presentation method, by means of which the attention of a user of the travel path device can be captured as easily and reliably as possible, in particular in order to provide information relevant to the use of the corresponding travel path device, in particular safety-related information.

[0006] This object is achieved by a travel path device according to claim 1 and by a method according to the parallel method claim. Advantageous developments of the invention are set forth in the respective dependent claims. Unless expressly denied, the features of the exemplary embodiments described below can be combined with one another.

[0007] A travel path device, in particular an escalator or moving walkway, is provided, comprising a drive unit, a circumferential handrail, a control unit, a measuring device, two boarding and alighting areas, and a step or pallet guided circumferentially therebetween. The measuring device comprises at least one sensor unit for measuring at least one operating parameter of the travel path device, the control unit being configured to output at least one control command (or at least one control command) as a function of time based on an instantaneous measurement signal or a measured value of the measuring device relating to the at least one operating parameter. The invention proposes that the travel path device comprises an optical display unit coupled to the control unit and arranged axially spaced from the circumferential handrail in at least one boarding and alighting area, and that the travel path device is configured to output visually perceptible operating information about the at least one operating parameter to a user, in particular also located at a position along the travel path, at least in the respective boarding and alighting area, by means of at least one display area of ​​the optical display unit, arranged at a height above the circumferential handrail. The display unit comprises a logic unit coupled / couplable to the control unit and configured to predefine the type and / or position, in particular the height, of the display / presentation of the visually perceptible operating information on the optical display unit, in particular as a function of the at least one operating parameter and / or as a function of time. This allows the user's attention to be drawn, in particular to safety-relevant situations, and targeted information transmission, wherein the scope of the transmitted information can also be increased compared to previously available display devices.

[0008] A logic unit (e.g., a computer) individually configured for each display unit optionally also enables central control of the information presentation for multiple display units (e.g., simultaneously displaying identical information) or display unit-specific personalized presentations, for example, time-dependent and / or as a function of the user's current relative position along the travel route system. This decentralized architecture also enables retrofitting or expansion of the display units used when an existing travel route system is already installed / operating on site. The content to be presented can also be individually compiled for each display area of ​​a display unit, particularly based on the current user traffic or, for example, the instantaneous brightness of the environment (instantaneous determining parameters, particularly system-specific and individual for each display unit, installation site-specific, or direction-specific). For example, the current user traffic itself can also be presented, for example by schematically displaying the respective relative positions of the individual users on the respective travel path device on each display unit in an installation comprising a plurality of travel path devices, for example arranged in a row. In this way, it is also possible, for example, to more easily identify peak traffic times in a building or an institution, thereby enabling, for example, advance planning of energy requirements. Or, in combination with an elevator installation, user guidance can also be achieved by recommending to users the priority use of the elevator installation or (one or more) travel path devices, depending on the current usage load.

[0009] Advantageously, the logic unit is configured to select the information to be presented on the respective display unit and to divide or organize the type and manner of presentation of the information on the at least two monitors of the display unit into at least two display areas, respectively, in particular in a highly position-specific manner (i.e., hierarchically, in particular because users tend to perceive or register the information at the top or at the leftmost first). The respective computer program may include graphics program code configured to display the respective information distributed across at least two or three display areas / areas of the respective monitors.

[0010] Optionally, the respective display unit is equipped with a Bluetooth interface or similar proximity sensor technology, which is common in particular in smartphones, so that a presentation can be implemented based on the precise instantaneous relative position of the respective user, in particular also based on an instantaneous proximity measurement value. The operating mode of the respective display unit, in particular the manner and method of distributing / presenting the displayed information, can be adapted based on the proximity measurement value. For example, the implementation can be different for a very fully loaded travel path device (with users on almost every step / platform) than for a very lightly loaded travel path device (for example, the lighting intensity in at least one display area can be dimmed when there are no users in a predetermined proximity range or depending on a distance threshold).

[0011] In this case, the corresponding sensor unit can be provided as a component of the measuring device or can be located separately therefrom and can include, for example, a load sensor related to the occupancy / load of the travel path device, a proximity sensor related to the instantaneous distance of the user from the display unit, a brightness sensor, in particular related to daylight or the environment, a temperature sensor and / or a humidity sensor or similar sensors.

[0012] In other words, the present invention can also be described as follows: The respective display unit has an internal computer (logic unit) that can individually combine the content to be presented and make it available for presentation on an integrated display area (panel), in particular also depending on the relative position (location) of the display unit relative to other display units of the travel path device. In this case, different decision parameters can optionally be implemented centrally in a / the (central) control unit of the travel path device and / or decentralized in the respective logic units, based on which the information to be displayed on the respective display area (panel) can be predetermined, for example:

[0013] i) (system-specific) operating information depending on the operating state of the travel path device (also referred to herein as the first information type), which can be switched, for example, via potential-free contacts in the travel path device; for this purpose, for example, a 24 V DC signal (depending on the state of the travel path device) is transmitted to a digital input of an integrated computer of a corresponding display unit; for example, a traffic light display is implemented in the form of a dynamic sign, by means of which, for example, the direction of travel of a step / pallet of the travel path device can be displayed, so that passengers can recognize from a distance which travel path device is in operation or whether the travel path device is ascending or descending, or if they are approaching the travel path device from the wrong direction;

[0014] ii) external (non-system-specific) information (herein referred to as the second information type, e.g., content related to manufacturer-specific promotions for advertising or marketing-related information dissemination), which can be transmitted, for example, via a digital interface (e.g., via TCP / IP or FTP) to a corresponding internal computer and stored, wherein, for targeted targeting of user groups, this information is preferably displayed in a time-controlled (but not necessarily time-dependent) manner, i.e., provided as a function of at least one time parameter (e.g., only in the morning between 07:00 and 08:00); such external information (including, in particular, advertising content) can, for example, include static content (in particular texts and images) and / or audio- and video-based multimedia video clips;

[0015] iii) Dynamic information, in any case related to a date / time point (referred to herein as the third information type), can be transmitted to a corresponding internal computer and stored in a corresponding display unit via a digital interface, such as information for orientation and guidance of customers (retail), travel information (infrastructure); for example, in a shopping mall, such information can indicate where which products or services can be found (e.g., location descriptions or spatial presentations such as floors and directions); in this regard, the operation of publishing current information at corresponding key locations or at corresponding target moments (e.g., the moment / position when the user is about to arrive at the corresponding floor or arrive at the corresponding platform) is also simplified, and the user needs to process less information that may not be relevant to him / her at all. In other words: instead of engraved or film-coated acrylic signs, electronic presentations can be made in a targeted manner at the ideal time or at the optimal relative position (i.e. the time or relative position of the user relative to the potential destination) using multiple display areas, such as LED display areas, wherein the corresponding presented information can be updated in a simple manner and without significant time delay, for example when the location situation (environment) and / or the supply of goods / services of the institution or place where the travel path device is located changes, or when it is necessary to present very time-sensitive information (third information type), such as train or bus timetables, such as displayed at a train station ("The train to destination XYZ is at platform 03"), or itinerary information displayed at an airport ("Flight XYZ123 is now boarding at gate 08"), or when, for example, it is necessary to remind of special events, such as exhibitions or similar, more likely non-scheduled events, being held in the institution where the travel path device is installed.

[0016] Such a display unit according to the invention may refer to a range of achievable functions, for example, also referred to as an infotainment traffic light column.

[0017] The scope of safety-related functions can advantageously be expanded individually depending on the installation situation, in particular by at least one of the following units / devices:

[0018] a) an emergency stop trigger interface, in particular in the form of a manually operable emergency brake, which, in particular at a relatively high installation height, requires the user to raise his arm in order to be able to reach the brake lever of the emergency stop trigger interface; in this way, the emergency stop function is also provided in such a way that actuation of the emergency brake is clearly visible to adjacent persons and thus also prevents misuse;

[0019] b) an integrated isolation unit, in particular comprising at least one belt-shaped people-guiding unit; this also enables further measures and advantages with regard to maximum safety, in particular a simple and practical isolation (no access), for example when an upper floor of a shopping mall is no longer accessible (e.g. at the end of opening hours or at the end of shop hours); isolation can also be achieved in a very quick and simple manner;

[0020] The functional scope can advantageously be expanded individually depending on the installation situation, in particular by at least one of the following accessories or components or modules:

[0021] c) at least one integrated light barrier and / or radar sensor; in particular, due to the light barrier function being positioned relatively far in front of the boarding and alighting area on a corresponding display unit (the light barrier or the corresponding radar sensor being positioned forward), faster identification of persons is possible, thereby further optimizing the control of the travel path device;

[0022] d) providing end posts for the safety curtain or the safety frame, or integrating corresponding mounting interfaces or couplings for the corresponding safety device; if the safety curtain is to be mounted on the travel path device, the corresponding display unit can serve as an end post, in particular for fastening the glass pane of the safety curtain and for providing additional stability.

[0023] It should be noted that a common monitor or display can also be provided for the individual display areas of the display unit. This means that the individual display areas do not necessarily have to be implemented via separate monitors or separate displays. It should also be noted that the display areas of the display unit can also be of the same or different types, with the individual display areas being driven independently of their type by an integrated logic unit (or by a computer), for example, the following types: LED, OLED, LCD, Nano-LED, LED film. A display unit having, for example, three display areas can selectively have one, two, or three of these types, particularly depending on the proper installation of the travel path device and / or the type of information displayed in each display area (e.g., depending on the required level of detail, which can be significantly less for symbols or colored lights than for textual signs or road signs).

[0024] According to one embodiment, the optical display unit emits visually perceptible operating information in a field of view that is arranged at least partially overlapping the boarding and alighting area in a top view, in particular by at least 50%, or that is arranged completely within the boarding and alighting area, for example a field of view with an opening angle in the range of 30-70°. This also enables, in particular, targeted information transmission, in particular only to users who are approaching the corresponding boarding and alighting area (or who are leaving the steps / pallet via the boarding and alighting area, depending on the direction of travel illuminated by the display unit). In other words: the display unit has at least one display area that is designed, oriented and / or configured so that the field of view defined by the corresponding display area at least partially overlaps the boarding and alighting area, in particular by at least 50%. Optionally, multiple display areas can be provided, each with a personalized field of view, particularly a first display area with a relatively narrow field of view (optimized for visibility at a distance) and a second display area with a relatively wide field of view. This second display area can also be oriented more strongly to the side of the boarding area (optimized for visibility at close range, particularly when the user is grasping the respective handrail or is directly in front of the respective handrail). In this way, the time point / moment of information dissemination can be more precisely predetermined, thereby facilitating user guidance based on the information that is most important / interesting at the respective moment.

[0025] As described elsewhere in the present invention, it is advantageous if the corresponding display unit also illuminates in both directions of travel, that is, it also communicates to users who are leaving the steps / pallets through the boarding and alighting area and, in other words, leaving the travel path device again. This also allows for efficient use of the display surface provided by the cylindrical display unit from both sides or in both transport directions. To this end, the display unit can be equipped with a receiving cavity or mounting means, for example, for two opposing monitors, that is, the display unit needs to be sufficiently deep.

[0026] According to the invention, the optical display unit has display areas on two opposite end faces pointing in both directions of travel of the travel path device, preferably at least two display areas in each case. This further improves information transmission, for example, even in very long travel paths where the user spends a relatively long time on the path and can also look around, for example, against the direction of travel.

[0027] According to one embodiment, the optical display unit is designed as a column, in particular having a column fixed to the ground, the column in particular having a height of at least 1 m, in particular a maximum height of 2.5 m, in particular having a width in the range of 20 cm to 50 cm, in particular the width of its corresponding display area also lies in this range, in particular a width of at least 20 cm. This provides particularly good visibility, so that detailed information (e.g., small fonts) or location diagrams can also be easily perceived, in particular more easily perceived than, for example, a smartphone screen, which is particularly helpful for elderly users to easily obtain information.

[0028] According to one embodiment, the optical display unit includes a plurality of display areas, each for a predetermined type of information, preferably based on at least one of the following display technologies: LED, OLED, LCD, Nano-LED, LED film, and in particular at least one first display area for a first type of information (preferably system-specific operating information, in particular safety-related system-specific operating information, such as availability and / or operational readiness information and / or malfunction information related to the direction of travel and specific to the boarding and alighting area) and at least one second display area, preferably arranged therebelow, for a second type of information (preferably directional information resulting from external circumstances, such as transient events, or location information of a predefinable destination from a target boarding and alighting area, and / or external, non-system-specific information, such as location-specific and time-specific media content of a currently offered product or service). This also creates a hierarchical structure related to the importance of the information provided and, in particular, facilitates user orientation, such that, for example, in a large shopping mall or airport with numerous travel path devices, corresponding information types can be regularly found at the same location or at a similar height.

[0029] According to one embodiment, the travel path device is configured to output, on at least one display area, visually perceptible operating information related to at least one operating parameter from the following group: the movement state of the travel path device (in particular, the first or second direction or the stationary state), the load state of the travel path device, the instantaneous energy consumption or energy efficiency, and the instantaneous load state of individual steps or pallets. This also facilitates, in particular, the transmission of information relating to technical aspects of the use and / or maintenance of the travel path device.

[0030] According to one embodiment, the optical display unit(s) are arranged laterally next to the respective boarding and alighting area, in particular in an axially aligned extension of the armrest. This also ensures an ergonomic arrangement and good visibility, especially without particularly unfavorable restrictions on the space requirements of the equipment or the user's maneuvering capabilities.

[0031] According to one embodiment, the travel path device includes at least two optical display units coupled to a control unit and arranged in each of the boarding and alighting areas. The device is configured to separately and decentralizedly output visually perceptible operating information about at least one of the following operating parameters: the motion state of the travel path device, the load state of the travel path device, instantaneous energy consumption or instantaneous energy efficiency, and the instantaneous load state of individual steps or pallets to users in the respective boarding and alighting areas using the respective optical display units. This also allows for different operating information to be displayed to users in the first boarding and alighting area than to users in the second boarding and alighting area, or for a user to be presented with a first operating information upon boarding the travel path device (e.g., "Please do not walk or run, especially if the moving walkway is heavily loaded") and a second operating information (e.g., "Please do not forget your luggage") upon exiting (leaving) the travel path device, or vice versa.

[0032] According to one embodiment, the operational information regarding at least one operating parameter includes at least one safety message, in particular a safety warning, in particular regarding the load status of the travel path device, and / or a time-dependent / time-specific operational readiness message and / or a malfunction message. This also enables, in particular, the reliable and efficient transmission of safety-critical information. This type of information is preferably displayed at the most hierarchically important position, in particular in the topmost display area.

[0033] According to one embodiment, the operational information relating to at least one operational parameter includes at least one safety information item. This safety information item is displayed (or can be displayed) in a display area, preferably at the top, of the display unit, in a visually perceptible manner, particularly in the manner of a traffic light display (including at least red and green) related to the driving direction, by being highlighted in color (especially red). This also simplifies the sorting of the displayed information, especially from a distance. This allows the user to quickly and easily identify whether the travel path device is in operation, whether traffic is accessible, or about to be reopened. Optionally, a countdown function can also be implemented, allowing the user to immediately see when the travel path device will be reopened, for example, when the driving direction will be changed again.

[0034] The information presented via the respective display areas can also be provided by implementing digital signage functions or digital signage measures involving the coupling of the control unit and the respective logic units of the respective display units according to the parameters described herein, in particular in a location-specific manner taking into account the respective installation locations of the respective display units. In a combination of multiple display units, each display unit can also be uniquely identified and addressed via at least one identification feature (key, code, logo, etc.). Optionally, a central control command can cause specific information to be presented simultaneously on multiple display units.

[0035] According to one embodiment, the optical display unit has at least three display areas arranged one above the other, each for a predefined type of information, preferably based on at least one of the following display technologies: LED, OLED, LCD, Nano-LED, or LED film. These display areas include a first display area for a first type of information (preferably system-specific operating information, in particular safety-related), a second display area arranged below it for a second type of information (preferably external, non-system-specific information), and a third display area arranged below it for a third type of information (preferably dynamic information related at least to a date / time, in particular current travel information). This not only expands the range and types of information presented but also allows for clearer structuring. A person skilled in the art can, for example, predetermine which display technology (in particular LED, OLED, LCD, Nano-LED, or LED film) is preferred, depending on the installation situation and / or the type of information to be displayed, and can also optionally combine these technologies, for example, depending on the size of the individual display areas.

[0036] According to one embodiment, the travel path device includes at least one additional optical display unit positioned centrally along the travel path of the steps or pallets between the boarding and alighting areas, and is configured to output visually perceptible information about at least one operating parameter to the user at a corresponding longitudinal position along the travel path using the additional central optical display unit. This allows for effective and efficient targeted information transmission to the respective user at a different relative position along the movement / travel path. In particular, since users tend to pass by individual display units relatively quickly (or if there is no desire to obstruct the flow of passengers / users), the repeated or varied presentation of information every 10 meters, for example, can also achieve a more uniform flow of users (i.e., users can be passed / transported without stopping), thereby further increasing the actual utilization of transport capacity.

[0037] According to one embodiment, at least one display unit of the travel path device has an emergency stop triggering interface, particularly located 1.5 m above pedestrian level. This also allows, in particular, for manually triggering safety measures directly and locally in response to displayed (safety-relevant) information. This allows for safer operation, particularly if the system itself does not have an emergency stop function or if the system's own emergency stop function is malfunctioning.

[0038] According to one embodiment, at least one display unit of the travel path device includes a separating unit, in particular integrated in an arrangement at least in the height section overlapping the handrail, and in particular includes at least one preferably deployable belt-like passenger guidance unit. This also facilitates the implementation of timely follow-up measures in response to an emergency stop or other operational faults or other necessary accessibility isolation.

[0039] According to one embodiment, at least one display unit of the travel path device includes a light barrier and / or a radar measuring unit, in particular a light barrier oriented laterally at least approximately perpendicular to the axial direction of the handrail and / or a radar measuring unit oriented axially away from the handrail, in particular designed as a combined light barrier and radar measuring unit, in particular with a display unit at an axial distance of at least 1 meter from the surrounding handrail. This also enables optimized use of the presentation means described herein, in particular demand-oriented and dependent on the currently present user. Preferably, the light barrier and / or radar measuring unit(s) are coupled to the logic unit of the corresponding display unit, in particular in such an embodiment that optically detecting a user triggers at least one presentation measure on at least one display area of ​​the display unit, in particular based on a distance threshold. Thus, for example, first information may be presented when a user approaches a distance of, for example, 2.5 meters (a first distance threshold), and second information may be presented when a user approaches a distance of, for example, 1.5 meters (a second distance threshold), and / or presentation may depend on whether a user is detected within the detection range of the light barrier and / or radar measuring unit.

[0040] According to one embodiment, at least one display unit of the travel path device has a coupling or mechanical interface to a safety curtain or safety cage, in particular in an axially aligned extension of the handrail, i.e., depending on the relative position of the display unit on the outer surface, facing the handrail or laterally toward the boarding area, in particular in a height section corresponding to the height of the handrail, in particular the coupling or mechanical interface, with at least one non-positive / positive fastening point, such as a screw connection or a purely positive connection. This also enables, in particular, an expanded functional range of the respective display unit with respect to lateral support, thereby further improving safety.

[0041] It is understood that signals, for example, regarding status information (e.g., regarding movement / operation and / or load status) can be generated from the logic or calculation or control unit of the travel path device, in particular via an electrical connection. The signals can be, for example, simple flags, such as those listed in the following truth table:

[0042] Signal A 24V DC Signal B 24V DC Signal C 24V DC Open x closure x intermittent x Fault x x x

[0043] Based on this, the (current) status of the travel path device can be detected using a module installed in the travel path device (herein referred to as a status module). The status module is advantageously configured to convert a 24V DC signal generated by the travel path device into a radio signal. This radio signal can be transmitted, in particular wirelessly, to the respective logic unit in the corresponding display unit (or column) using the status module (optionally using a communication module and optionally also using a control unit) and can be evaluated by the logic unit. The display unit can advantageously be equipped with a 230V AC connection (connected solely via a radio signal). The status module can also optionally be configured as a component or assembly of the control unit.

[0044] According to one embodiment, the travel path device includes a status module configured to convert a DC signal generated on the travel path device side into a radio signal. The travel path device is configured to transmit the radio signal to a corresponding logic unit in the corresponding display unit, wherein the corresponding display unit is preferably connectable to the power grid via an AC current connection. This enables wireless signal transmission based on a DC signal, particularly a 24V DC signal. For example, commonly used near-field communication protocols can also be considered as radio signals. Thus, the conversion can be performed centrally, while the processing of the corresponding signal or the display of related information can be performed decentralized at locations that are convenient for the user. This also facilitates a centralized architecture for communication with the corresponding display unit, while also advantageously streamlining the overall arrangement.

[0045] Advantageously, each optical display unit of the travel path device and / or at least one additional optical display unit arranged centrally along the travel path has multiple display fields, with at least one display field being arranged oppositely and emitting in opposite directions. This improves the perceptibility of information, and thus also the user's level of awareness, particularly at the corresponding location along the travel path, i.e., not necessarily only in the corresponding boarding and alighting areas. Thus, for example, safety warnings can be conveyed very clearly and purely visually, even when the display units are arranged only in the boarding and alighting areas, because, for example, a user located in the middle of the escalator can perceive the information both in the direction of travel and in the direction opposite thereto, particularly if the corresponding display fields have a large area.

[0046] The above-mentioned object is also achieved by a method according to the corresponding parallel method claim, in particular in a travel path device according to the present disclosure, namely by a method for providing visually perceptible information in at least one boarding and alighting area of ​​a / the travel path device, in particular in an escalator or a moving walkway, each of the escalator or moving walkway having a drive unit, a surrounding handrail, a control unit, a measuring device, two boarding and alighting areas, and steps or pallets guided therebetween, wherein at least one operating parameter of the travel path device is detected, wherein at least one control command for providing information is output as a function of a momentary measurement signal or measured value related to the at least one operating parameter and optionally also as a function of time; wherein at least part of the provided information is provided to a user of the travel path device as visually perceptible operating information related to the at least one operating parameter at a height above the surrounding handrail, wherein the type and / or position, in particular the height, of the provided visually perceptible information is predetermined, in particular distributed in the respective boarding and alighting areas of the travel path device, in particular predetermined as a function of the at least one operating parameter and / or as a function of time. Information is provided via at least one optical display unit on opposite end faces of the display unit in both directions of travel of the travel path device, using display areas displayed in opposite directions of travel. The aforementioned advantages are particularly advantageous in that the visibility of currently relevant / important information, particularly safety-related information, can be optimized, either centrally for the entire travel path device (i.e., simultaneously on multiple display units in at least two boarding and alighting areas) or individually and decentralized for each display unit or longitudinal area. This not only provides more effective user guidance but also significantly improves the level of safety when using the travel path device.

[0047] According to one embodiment, visually perceptible information is presented on multiple display areas according to predefined information types, specifically a first information type (preferably system-specific operating information) on a first display area, a second information type (preferably non-system-specific information) on a second display area arranged below it, and optionally a third information type (preferably dynamic information at least related to a date / time point) on a third display area also arranged below it. This also makes it easier for users to purposefully access specific information.

[0048] According to one embodiment, at least two types of information are output to at least two display areas of the corresponding display unit in a distributed manner based on instantaneous measurement signals or measurement values ​​related to at least one operating parameter and also based on time, in particular also based on the instantaneous measurement values ​​of the light barrier and / or radar measurement unit of the corresponding display unit, that is, based on the instantaneous presence of at least one user. This also enables interaction with the corresponding user, so that the user's attention can be obtained in a more targeted manner. For example, in particular in the case of relatively long travel path devices (such as moving walkways over very long lengths / sections or escalators over very large height differences), the travel time (first information type) can be displayed at the current moving speed of the travel path device, in particular the current operating time of the public transport (third information type). In this way, the user can quickly determine whether he needs to speed up.

[0049] According to one embodiment, the DC signals generated by the travel path device are converted into radio signals and transmitted to the respective logic units of the corresponding display units, in particular via the status module of the travel path device. This also facilitates a streamlined communication architecture, wherein the respective display units only need to be connected via a single 230VAC power connection, for example.

[0050] The aforementioned object is also achieved by a computer program product comprising commands that, when executed on a computer, cause the computer to implement a method for providing visually perceptible information according to the present disclosure. In particular, the computer program product is configured to determine the type and manner of information presentation in at least one display area on each display unit of a travel path device based on at least one determining parameter related to the current user flow or at least one environmental parameter (e.g., brightness). Based on the aforementioned advantages, this also facilitates decentralized optimization of the presentation on each individual display unit. The computer program is preferably implemented in such a way that the logic unit is configured to output the centrally provided information in a decentralized manner on the respective display units via at least two monitors, in particular in a different / personalized manner on each monitor (e.g., travel directions specifically tailored to the potential destinations of the respective user), in particular in at least two display areas on each of the at least two monitors.

[0051] The above-mentioned object is also achieved by using at least one columnar optical display unit arranged in at least one boarding and alighting area of ​​a travel path device, in particular in axial alignment with a surrounding handrail of the travel path device, wherein a measuring device detects at least one operating parameter of the travel path device and outputs a corresponding measurement signal to a control unit of the travel path device, wherein the optical display unit outputs visually perceptible operating information about the at least one operating parameter to a user by means of at least one display area of ​​the optical display unit in the corresponding boarding and alighting area, located at a height above the surrounding handrail, in particular by means of at least two display areas radiating in opposite directions of travel, wherein a logic unit of the display unit coupled to the control unit predetermines the type and / or position, in particular the height, of the display / presentation of the visually perceptible operating information on the optical display unit, in particular as a function of the at least one operating parameter and / or as a function of time. Information is provided by the at least one optical display unit on opposite end faces of the display unit in both directions of travel of the travel path device by means of the display areas radiating in opposite directions of travel. This approach achieves the aforementioned advantages, in particular with regard to combining, in particular, safety-related display measures with other vehicle-related safety measures, such as lateral protection or isolation. In this way, human-computer interaction or corresponding interfaces can also be further improved.

[0052] In summary, in travel path devices, users must exercise particular caution when logging on and off, particularly due to the surrounding steps / pallets. However, at the same time, each user also desires information about the operating status or external conditions unrelated to the system, such as information regarding the surroundings of the travel path device. According to the present invention, a travel path device is provided that includes an optical display unit coupled to its control unit and arranged axially spaced apart from a surrounding handrail of the travel path device in at least one of the boarding and alighting areas of the travel path device. The device is configured to output visually perceptible operating information relating to at least one operating parameter to the user using at least one display area of ​​the optical display unit arranged at a height above the surrounding handrail in the respective boarding and alighting area. The display unit is configured to predefine the type and / or location of the display / presentation of the visually perceptible operating information on the optical display unit, particularly as a function of at least one operating parameter and / or as a function of time. This makes it possible, for example, to effectively provide safety-related information in a visually perceptible manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] First, the present invention will be generally explained with reference to all figures and drawings. Features or specific aspects of the present invention will be described with reference to the corresponding drawings.

[0060] The present invention relates to a travel path device 10 (in particular an escalator or moving walkway), which has a drive unit 11, a central control unit 12 (optionally equipped with a wireless communication module and / or a signal conversion module), at least one measuring device 13 with at least one sensor unit 16, at least one first (e.g. lower) and at least one second (e.g. upper) boarding and alighting area 14a, 14b, a circumferentially guided step or platform 15 and at least one circumferential handrail 17 or at least one pair of oppositely disposed circumferential handrails.

[0061] Travel path device 10 includes optical display units 20a, 20b in both the first and second boarding / unboarding areas, and optionally, an additional optical display unit 20' can be positioned centrally between the boarding / unboarding areas. In the boarding / unboarding areas, display units 20a, 20b are preferably each mounted using a column (base) 21 fixed to the floor, and any additional centrally positioned display unit 20' is preferably each mounted using a bottomless (non-contacting) fixed base 21', in particular, on a side wall of travel path device 10.

[0062] The respective display units 20a, 20b preferably have a plurality of display areas 23, in particular first, second, and third display areas 23.1, 23.2, 23.3, wherein at least one opposite display area 23a (or second monitor) emitting in the opposite direction is optionally also provided. For example, the same display area of ​​the first end face is also provided / arranged on the opposite end face of the display unit.

[0063] At least one display area is arranged in a preferably higher section Z23, for example in the height range between the head and chest of a person of standard height, in particular significantly above the height z17 of the handrail relative to the ground or the step / support plate.

[0064] Each display unit 20a, 20b has a logic unit or arithmetic unit 25 and optionally also a communication module 24 for wireless communication, but alternatively or additionally, a wired connection to the central control unit is also possible. A / the communication module 24 or the corresponding functional area can also be installed in the logic / rithmetic unit 25.

[0065] Advantageously, the measuring device 13 comprises at least one light barrier and / or radar measuring unit 29 , in particular with a plurality of measuring points 29 . 1 individually assigned to each display unit, for example at different heights.

[0066] Advantageously, each display unit also includes at least one of the following further components: a mounting interface or coupler 26 for fixing a safety curtain / safety frame, an emergency stop trigger interface 27 (for example designed as a lever or handle), an isolation unit 28, in particular having at least one strip-shaped personnel guidance unit 28.1 which is supported behind a closable baffle of the display unit and can be unfolded or pre-tensioned and rolled up.

[0067] The main axial extension direction x of the travel path device corresponds to the respective movement direction of the user (at least in the case of a travel path device which generally extends one-dimensionally or two-dimensionally along a constructively predefined spatial plane xz), and in the case of an escalator also in the vertical direction z, wherein the respective display unit is arranged at an optimized axial distance x20 from the respective handrail end, and wherein the respective display area is arranged in an advantageous height section z23, in particular above or above the handrail.

[0068] exist Figure 1A , an escalator 10 is shown, which has a first display unit 20a in the lower boarding and alighting area 14a and a second display unit 20b in the upper boarding and alighting area 14b. Figure 1A, a status module 18 is shown, by means of which a DC signal generated on the travel path device side is converted into a radio signal, wherein the radio signal is transmitted to a corresponding display unit in order to be evaluated by the corresponding display unit. The module 18 can also be integrated in the control unit 12. Figure 1B 1 shows a moving walkway 10 having a first display unit 20a in a first boarding and alighting area 14a and a second display unit 20b in a second boarding and alighting area 14b. In addition to the first and second display units 20a, 20b, an intermediately arranged display unit 20' is also shown or provided. Figure 1C In FIG. 1 , for a travel path device 10 (escalator or moving walkway), a field of view 22 defined by a corresponding display area is shown on one of the display units 20b. The corresponding display area 23.1 can be oriented at a specific angle to its viewing axis X2, in particular slightly laterally relative to the boarding area 14b, and project into the field of view 22 at an opening angle α (optionally tapering or widening). The opening angle α can be adapted to the actual situation and installation conditions, in particular so that users who are slightly more laterally deviated from the field of view or the viewing axis by a few degrees are no longer or significantly less exposed to the illumination or targeting of the display area. This also improves user guidance by limiting the time or relative position at which the user engages with the presented information. Each display area can have its own / unique viewing axis and a field of view of a unique width / size, or a unique opening angle α. Note: The illustrated opening angle α here illustrates a tapering field of view; alternatively, the field of view can also widen with increasing distance, i.e., have an opening angle α that results in a widening or enlargement of the area in which the presented information is perceived.

[0069] As an alternative to the standing position of the display unit shown in FIG1 , the display unit can also be arranged, for example, between the end areas of two adjacent parallel handrails when escalators or moving walkways are arranged side by side (a common installation method when two travel directions are to be realized simultaneously), thereby also creating a synergistic effect, especially in the display areas arranged on the end faces on both sides (for example, by two monitors, see FIG6 ), so that users of two travel directions or two travel path devices can be targeted simultaneously.

[0070] exist Figure 2 As can be seen, at least one display area 23.1 can occupy a relatively large area, for example, extending over a height section of, for example, 0.7 m and a width of, for example, 0.25 m. Depending on the application scenario, this presentation area can be selectively and uniquely divided into a plurality of independently recordable display areas (or display regions), in particular, into two or three display areas / regions.

[0071] In addition, from Figure 2In FIG, the square basic shape of the display unit can be seen, ie the configuration with baffles or outer surfaces oriented at least approximately parallel or perpendicular to one another. Figure 2 A 230VAC current connection 21 . 1 is shown by way of example in FIG.

[0072] exist Figure 3 As can be seen in FIG, the display unit has two opposite display areas 23, 23a, which are each provided by a monitor installed in a column, for example.

[0073] exist Figure 4 , the available presentation area is divided into three display areas by way of example, and the correlation of specific information types with the corresponding display areas is shown. A first information type I1, i.e., system-specific operating information, such as an arrow with a green background as a direction indicator, or a stop sign with a red background (no passage) is presented on the first display area 23.1. A second information type I2, i.e., non-system-specific information, such as information about the current weather in the surrounding environment, is presented on the second display area 23.2 arranged below it. A third information type I3, i.e., information related to a date / time point, such as a train departure time (such as "13:15"), or delay prompts for transportation such as buses, trains, airplanes, and autonomous vehicles, is presented on the third display area 23.3 arranged below it. The individual display areas can also have different sizes of fields of view and / or differently oriented visual axes (orientations), in particular depending on the importance of the information displayed. In addition, Figure 4 The shielding plate 21a is shown in the region of the superposed fixing means 21b (eg screw connections) for assembling and shielding the column.

[0074] Figure 5A 、 5B , more details of the housing of the column are shown, in particular with respect to the various receiving portions or mounting interfaces on the lateral sides of the housing.

[0075] Figure 6A 、 6B 1 and 2. The mounting / fixing of the two monitors 20.1 and 20.2 arranged opposite each other is shown in more detail. The two monitors are used for the display areas 23 and 23a. In addition, the following components are shown: a fixing mechanism 21b, a receiving portion 21c for an optionally additional signal light unit or for mounting a cover (see FIG. Figure 2 ), housing part 21d, such as an outer cover, cover or baffle, and one / the monitor mounting element 21e (which also comprises, for example, at least one threaded rod) which is particularly preferably also arranged centrally in the back area of ​​the two opposite monitors at half height. In addition, Figure 5A and 6BA mounting cover 26.1 is shown, which can be used, for example, to couple a safety device, such as a safety curtain or a safety frame.

[0076] Figure 6B The position of light barrier / radar measuring units 29 , 29 . 1 , which may optionally be implemented in addition, is shown by way of example.

[0077] The installation positions of the components shown in the figures, in particular components 26 and 28 , can be varied or at least partially interchanged, in particular depending on the arrangement of the display unit relative to the armrest and the boarding area.

[0078] Figure 7 The steps of a method for providing visually perceptible information on a display unit of a travel path device in at least one boarding and alighting area are schematically illustrated. The method includes outputting at least one control command for providing information based on instantaneous measurement signals or measured values ​​related to at least one operating parameter and optionally also based on time (step S3), in particular for visually providing information as operating information related to at least one operating parameter at a height position above a / the wraparound handrail of the travel path device. The method includes detecting at least one operating parameter of the travel path device (step S1). The method includes presetting the type and / or position of the visually perceptible information to be provided, in particular the height position defined by one of a plurality of display areas of the display unit, centrally by a control unit according to a first control command and / or decentralized by a logic unit of the display unit according to a second, priority control command (step S2), in particular based on at least one operating parameter and / or based on time. In conjunction with steps S2 and / or S3, the respective information can be presented locally distributed across a plurality of display areas, in particular when at least three information types are distinguished across three display areas, in particular also based on instantaneous measurement values ​​of light barriers and / or radar measurement units of the respective display units. Step S2 and / or S3 may include a sub-step S3.1: compiling a graphics program code to display at least two types of information in at least two display areas of a monitor.
