Description

Technical Field

[0001] The technology described herein generally relates to elevator installations in buildings. Embodiments of the technology particularly relate to an elevator installation having an elevator operating device for passengers with limited mobility and a method for operating such an elevator installation. Background Art

[0002] In buildings with elevator systems, elevator operating devices are located on each floor, allowing passengers to call the elevator using these devices. In known elevator systems, the elevator operating devices located on each floor have up / down buttons, allowing passengers to enter their desired direction of travel. In some such elevator systems, the elevator car has a car operating device, which passengers in the car can use to enter their desired destination floor. In other known elevator systems, passengers can enter their destination floor using an elevator operating device already on the floor. For this purpose, elevator systems are equipped with destination call control technology, and the elevator operating devices located on each floor each have a keyboard, a touch screen, and / or a data acquisition device (e.g., in the form of an RFID reader as known from EP 0 699 617 B1) for entering the destination floor.

[0003] Elevator operating systems should also be able to conveniently and reliably serve passengers with limited mobility. Physical limitations can, for example, relate to vision, hearing, or physical mobility. Various approaches are known to meet these requirements. For example, elevator operating systems that have or display a special button (e.g., with a wheelchair symbol) are well known. Pressing this button switches the elevator system to an operating mode suitable for disabled passengers. Furthermore, for example, EP 2 331 443 B1 discloses that an elevator operating system with a touch screen switches to a special input mode if an erratic movement is detected on the touch screen.

[0004] While the above methods make it easier for physically limited passengers to operate elevator equipment, smooth touch screens may still be difficult to operate, especially for visually impaired passengers. Therefore, there is a need for technology that makes operation easier. Summary of the Invention

[0005] One aspect of the technology described herein relates to an elevator system in which an elevator car can move between floors under the control of an elevator controller. The elevator system includes an elevator operating device and an activation device. The elevator operating device is communicatively connected to the elevator controller and is located on a floor. The elevator operating device includes a first radio, an audio device, and a touch screen for inputting a passenger's desired destination floor and outputting travel information. The activation device includes an operating device accessible to the passenger and a second radio device for radio communication with the first radio device. The activation device is located on one floor within radio range of the elevator operating device. The second radio device is designed to emit an activation radio signal when a passenger operates the operating device. The elevator operating device is designed to switch from normal operating mode to a special operating mode when the first radio device receives the activation radio signal. In the special operating mode, operating instructions are generated for a passenger-input call and the system switches back to normal operating mode when the input call is completed.

[0006] Another aspect of the present technology relates to a method for operating an elevator system, wherein elevator operating devices communicatively connected to an elevator controller are arranged on floors, and an activation device is arranged on one floor within radio range of the elevator operating device located there. The elevator operating devices have a normal operating mode and a special operating mode. The method includes the elevator operating device receiving an activation signal initiated by a passenger at the activation device. Upon receiving the activation signal, the special operating mode of the elevator operating device is activated, wherein the elevator operating device switches from normal mode to special operating mode. The elevator operating device then executes a procedure in an operating manual, thereby providing assistance to the passenger who initiated the activation signal when entering a call on the elevator operating device. After the passenger completes the call entry, the destination call is transmitted by the elevator operating device to the elevator control system. The elevator operating device communicates travel information to the passenger, wherein the travel information indicates the elevator car determined by the elevator controller and serving the destination call. After the communication of the travel information is completed, the special operating mode of the elevator operating device is deactivated, wherein the elevator operating device switches from the special operating mode to normal mode.

[0007] The technology presented herein creates an elevator system in which an activation device according to the technology presented herein can be advantageously used in combination with known elevator operating devices in which a destination floor can be entered on a touch-sensitive screen (touch screen). The use of the elevator operating device can be particularly challenging for visually impaired passengers. The technology presented herein offers the advantage that passengers, particularly those with limited vision, can conveniently access their desired destination floor using an elevator operating device with a touch screen. The activation device allows these passengers to activate a special operating mode of the elevator operating device, such as that used in elevator systems with destination call control technology. In this special operating mode, passengers are assisted in entering calls. Passengers without physical limitations, on the other hand, can continue to use the elevator operating device with which they are already familiar.

[0008] The activation device can be considered an extension component to the elevator operating device. Since communication between the activation device and the elevator operating device occurs via radio, installation effort is minimal. Furthermore, in one embodiment, known and widely available radio technology, in particular Bluetooth technology, is used.

[0009] Compared to an elevator operating device, the activation device has a reduced functionality; it only needs to generate and emit an activation signal. Depending on the design of the activation device, an acoustic signal generator and / or an illumination device can be provided. Consequently, the activation device according to the technology presented here has a low level of technical complexity and is therefore also cost-effective.

[0010] In one embodiment, the elevator operating device and the activation device each have a housing, wherein the housing of the activation device is arranged adjacent to the housing of the elevator operating device located adjacent thereto. The housing of the activation device can be arranged on the housing of the elevator operating device. In one embodiment, the activation device can be arranged on the front side of the elevator operating device that is visible to the passenger; for example, the activation device can be glued to the front side of the elevator operating device. This allows the activation device to be arranged flexibly and independently of the elevator operating device, and the housings can be arranged in contact with each other or at a greater or lesser distance from each other.

[0011] Flexibility in layout is also provided by the fact that, in one embodiment, the activation device is equipped with a battery or another electrical energy storage device. In another embodiment, the activation device is equipped with a button connected to the electric transducer. When the button is pressed, the electric transducer provides the energy to transmit the Bluetooth signal. Therefore, there is no need to provide a separate power supply line for the activation device. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following uses embodiments in conjunction with the accompanying drawings to explain various aspects of the improved technology in more detail. In the accompanying drawings, the same elements have the same reference numerals.

[0014] Figure 2 Schematic diagram showing an exemplary elevator operating device and an exemplary activation device, which are Figure 1 The elevator equipment is arranged on the floor; and

[0015] Figure 3 The present invention shows an exemplary illustration of an exemplary embodiment of a method for operating an elevator installation. DETAILED DESCRIPTION

[0016] Figure 1 is a schematic diagram of an exemplary situation in a building 2 having a plurality of floors L, L1 which are served by an elevator system 1. Floor L may be the entrance hall of the building 2, from which passengers P enter the building 2 and from which they leave the building 2. When a passenger P enters floor L, he can then use the elevator system 1 to reach each floor L1 of the building 2, provided he has the appropriate access rights. For the sake of illustration, Figure 1 In the figure, only the elevator controller 13, the drive machine 14, the sling 16 (for example a steel cable or a flat belt), the elevator car 10 (hereinafter also referred to as the car 10) suspended on the sling 16 and capable of traveling in the shaft 18, a plurality of elevator operating devices 4, 4a and the activation device 6 are shown. A person skilled in the art recognizes that the elevator system 1 can also include a plurality of cars 10 in one or more shafts 18, which are controlled by a group controller. Instead Figure 1 In contrast to the traction elevator shown in FIG, the elevator system 1 can also have one or more hydraulic elevators.

[0017] The elevator system 1 can be designed according to one of the aforementioned control technologies (up / down control or destination call control). A person skilled in the art will recognize that the elevator operating devices 4, 4a should be designed and arranged accordingly, depending on the control technology implemented in the building 2. The aforementioned control technologies are known to those skilled in the art, so a detailed explanation is unnecessary; hereinafter, this will be discussed only to the extent that it appears to be helpful in understanding the technology presented here.

[0018] If the elevator device 1 is equipped with a destination call controller, the elevator operating device 4 is arranged on the floors L, L1 and is connected to the destination call controller 12 (DCC) via the communication network 22. Passenger P can input the desired destination floor on the floors L, L1 through the elevator operating device 4; when the passenger P inputs the destination floor (that is, inputs the destination call), the information of the boarding floor and the destination floor can be formed. The boarding floor is generated by the position of the elevator operating device 4 that inputs the destination floor. The destination call control device 12 allocates an elevator car 10 to the input destination call, and the elevator controller 8 (EC) controls the travel of the allocated elevator car 10 according to the destination call. In the car 10, a travel request to the destination floor cannot usually be input; in Figure 1 The elevator operating device 4 a and the activation device 6 , which are indicated by dashed lines in the car 10 , are not provided in the elevator system 1 with the destination call controller.

[0019] If the elevator device 1 is equipped with an up / down control mechanism, the elevator operating device 4 is arranged on the floors L and L1, and the passenger P can input the required travel direction on the elevator operating device 4. The required travel direction is Figure 1 In the elevator operating device 4 (on the floor side) shown in FIG, a touch screen is designed to display two travel directions, or it is designed as two direction buttons. Figure 1 The destination call control device 12 shown in FIG. 1 does not have an up / down control mechanism in the elevator system 1. The elevator operating devices 4 on floors L and L1 are connected to the elevator controller 13 via a communication network 22. The desired destination floor is then input to the elevator operating device 4a located in the car 10. The communication line 20 connects the (car-side) elevator operating device 4a to the elevator controller 13. The current position of the car 10 (and therefore the landing floor) can be stored in the elevator controller 13; for example, this position was determined during the last trip of the car 10.

[0020] An exemplary embodiment of the technology described herein will be described below primarily based on an elevator installation 1 equipped with a destination call controller. A passenger P can enter a desired destination floor L, L1, on an elevator operating device 4 at floors L, L1. For this purpose, the elevator operating device 4 is, for example, each equipped with a touchscreen 11; the touchscreen 11 is also referred to below as a touchscreen 11. The configuration of such a touchscreen 11 and the technology used therein, in particular the display and input options on the flat operating interface of the touchscreen 11, are known to those skilled in the art. For example, the elevator operating device 4 displays the destination floor on the operating interface (e.g., in the form of a separate numbered field) along with any associated, floor-specific information (e.g., restaurant, parking lot, entrance hall). The elevator call (destination call) corresponding to the elevator car 10 serving the elevator call can be notified to the passenger P via a display on the operating interface and a voice message via the audio device 9.

[0021] According to the technology described herein, an elevator operating device 4 includes a radio device 5, which is arranged in the housing 24 of the elevator operating device 4 together with a touch screen 11. An activation device 6 includes a radio device 7, which is arranged in the housing of the activation device 6. The radio device 7 is designed to emit an activation radio signal when a passenger P operates the activation device 6. The radio device 7 transmits the activation radio signal with selected radio power and directional characteristics, which are selected so that the activation radio signal can be reliably received within a specific radio range and direction. The radio device 5 of the elevator operating device 4 is arranged within the radio range and is designed to receive the activation radio signal. In one embodiment, the activation radio signal is transmitted and received using Bluetooth technology, such as Bluetooth Low Energy (BLE). Those skilled in the art will appreciate that other wireless technologies, such as Wi-Fi HaLow / IEEE 802.11ah and Zigbee, may also be implemented.

[0022] exist Figure 1In the illustrated case, the technology presented here can be advantageously utilized. Summarized briefly and by way of example, the technology presented here enables passengers P with physical limitations, particularly limited vision or blindness, to conveniently and reliably input elevator calls in an elevator installation 1 equipped with a touchscreen 11 for call input. In contrast, passengers P without physical limitations can continue to use the elevator operating device 4 in the manner familiar to them, for example, from known elevator installations 1 with destination call control technology. A blind passenger, for example, can be guided to one of the activation devices 6. For this purpose, an acoustic signal generator, for example, which generates a harmonic clock tone signal with a low clock frequency (e.g., approximately 1 to 4 Hz or lower), and / or a guidance system for the blind, such as a tactile floor guidance system consisting of visual and tactile contrasting floor indicators (grooves and knob plates), can be provided.

[0023] If passenger P operates the activation device 6, it emits an activation radio signal, causing the elevator operating device 4 to switch from normal operating mode to a special operating mode. In normal operating mode, the elevator operating device 4 generates, for example, a graphical operating interface that passenger P can operate in a known manner by touching and reading information. In special operating mode, the elevator operating device 4 generates operating instructions for passenger P to input a call. The activation device 6 is located on or within the elevator operating device 4. If passenger P operates the activation device 6, passenger P is also located on or within the elevator operating device 4. The operating instructions generated by the elevator operating device 4 are thus perceptible, in particular audible, to passenger P. If passenger P follows the operating instructions and interacts with the elevator operating device 4 accordingly, passenger P is assisted in inputting the call. If the call input is completed by conveying travel information to passenger P (e.g., the assigned car 10, the time the car will arrive at the boarding floor, and / or the location where the car can be boarded from the position of the elevator operating device 4), the elevator operating device 4 switches back to normal operating mode.

[0024] exist Figure 1 In certain embodiments, the activation device 6 may be configured with an identification device 26 on the passenger side. The identification device 26 may, for example, have a wheelchair symbol or other identification on the operating interface to indicate its intended use for physically restricted passengers P. Depending on the configuration, the identification device 26 may include Figure 2 The lighting device 44 shown in FIG. 1 is used to illuminate the operating interface, for example. Figure 2 The sound signal generator 42 shown in FIG. 4 may be included in the identification device 26 .

[0025] Figure 2 A schematic diagram shows an embodiment of an elevator operating device 4 and an activation device 6, as shown in FIG. Figure 1The elevator system 1 is available on floors L and L1. The elevator operating device 6 can be communicatively connected to the elevator controller 13 (EC / DCC) via the communication network 22. The elevator operating device 4 has a housing 24, which allows it to be arranged on a building wall, an elevator door frame, or vertically on the ground. The activation device 6 has a housing 36, which can be arranged on a building wall, an elevator door frame, or on or next to the elevator operating device 4. In the elevator car 10, the elevator operating device 4a is arranged on the car interior wall or on or next to the elevator operating device 4a. Those skilled in the art will recognize that if the elevator operating device 4 and the activation device 6 are mounted on a building wall or on the door frame of the elevator door on the floor side, the housings 24 and 36 can be omitted if necessary. Those skilled in the art will also recognize that the elevator operating device 4 and the activation device 6 are arranged at a user-friendly or standard height.

[0026] In the illustrated embodiment, a touch screen 11, a central control and processing unit 32 (CPU), a lighting device 34, an audio device 9 (e.g., including an electroacoustic converter), and a communication device 30 (PoE, Power over Ethernet) are arranged in the housing 24 of the elevator operating device 4. Furthermore, a radio device 5 for receiving (RX) activation radio signals is arranged in the housing 24. The central control and processing unit 32 is communicatively connected to the aforementioned components to ensure the operation and tasks of the elevator operating device 4.

[0027] Touchscreen 11 includes a processor 28 that controls its operation and primarily generates an operating interface. Because a transparent glass panel (not shown) covers touchscreen 11, the input fields displayed on the operating interface are visible to passengers. Processor 28 is connected to a central control and processing unit 32 and generates a signal, for example, when passenger P touches an input field with a finger. The input field corresponds to the destination floor, allowing for the display of additional floor-specific information. The structure and function of the touchscreen are well known to those skilled in the art and therefore require no further explanation.

[0028] The lighting device 34 is used to illuminate the operating interface of the elevator operating device 4, either entirely or in certain areas. Under the control of the central control and processing device 32, the lighting device 34 can illuminate the operating interface so that the displayed input fields can be perceived by passengers (without visual obstruction), particularly under poor lighting conditions. The lighting device 34 can also illuminate the operating interface or individual input fields with colored light, for example, to confirm the entry of an elevator call. In one embodiment, the lighting device 34 includes one or more LED light sources.

[0029] A passenger can enter an elevator call (target call) to any desired target floor by selecting the target floor on the elevator operating device 4 by touching one of the displayed input buttons. If a car 10 is assigned to the target call, the central control and processing device 32 controls the touch screen 11 (or its processor 28) to display the identifier (e.g., letters or numbers) of the car 10 serving the target call and, if necessary, the direction on its operating interface 28. In addition, the central control and processing device 32 can control the audio device 9 to generate a corresponding voice message (e.g., car and direction information). This is particularly helpful for visually impaired passengers P to find their way around the building after entering a call.

[0030] The radio device 5 is designed to receive the activation radio signal, convert it into an electrical activation signal and forward it to the central control and processing device 32. The central control and processing device 32 recognizes that it is an activation signal and then switches the elevator operating device 4 from the normal operating mode to the special operating mode. In the special operating mode, the central control and processing device 32 processes the determined and stored procedures (procedures), as described elsewhere in this description in conjunction with Figure 3 As described.

[0031] In an embodiment of the elevator operating device 4, an alternative or additional option for call input can be provided. With this option, a portable communication device of the passenger P (e.g. mobile radio / mobile phone, smartphone, tablet) can be used for call input, and communication between the radio device 5 and the communication device is also possible, for example using the aforementioned Bluetooth technology.

[0032] In the illustrated embodiment, the radio device 7, the sound signal generator 42, the processor 40, the operating device 38, and the (optional) lighting device 44 are arranged in the housing 36 of the activation device 6. The processor 40 is directly or indirectly connected to the above-mentioned components; for example, when the operating device 38 generates an operating signal when it is operated by the passenger P, the processor 40 controls the radio device 7. The radio device 7 then emits an activation signal.

[0033] In one embodiment, the processor 40 controls the sound signal generator 42 to generate an audible tone signal. The tone signal can be, for example, an (audible) clock harmonic tone signal with a low clock frequency. In the field of providing assistance to the blind, for example, sound signal generators are known that generate tone signals with a clock frequency of approximately 1 to 4 Hz. The tone signal serves as a position signal, which allows the passenger P to locate themselves in space and move toward the signal generator 42.

[0034] In one embodiment, the functions of the operating device 38 and the functions of the radio device 7 can be integrated into a module, such as a push-button transmitter module configured according to BLE (Bluetooth) technology (PTM215B from Firma EnOcean GmbH, Germany). The module has a plurality of buttons or toggle switches, a Bluetooth radio device, and an electric transducer provided for powering the module. When one of the buttons is pressed, the electric transducer provides energy for transmitting the Bluetooth signal. A person skilled in the art will recognize that a battery can also be provided in the activation device 6, so that, for example, the sound signal generator 42 and, if necessary, the (optional) lighting device 44 can be operated even when no button is pressed and the electric transducer is not providing any power.

[0035] The communication network 22 connects the elevator operating devices 4 to the elevator controller 13, thereby enabling communication between the elevator controller 13 and the elevator operating devices 4. For this communication, the elevator operating devices 4 and the elevator controller 13 can be directly or indirectly connected to the communication network 22. The communication network 22 can include a communication bus system, individual data lines, or a combination thereof. Depending on the embodiment of the communication network 22, the elevator controller 13 and each elevator operating device 4 can be assigned individual addresses and / or identifiers, allowing, for example, the elevator controller 13 to send messages specifically to the desired elevator operating device 4. Communication can be performed using a protocol for wired communication, such as the Ethernet protocol. As described above, in one embodiment, the elevator operating devices 4 are supplied with power via the communication network 22 (PoE).

[0036] With the basic system components and their functions of the above-mentioned elevator system 1 understood, Figure 3 To introduce the Figure 1 An exemplary method for an elevator installation 1 shown in FIG, in particular for one of its elevator operating devices 4 . Figure 3 An exemplary flow chart of the method is shown, which starts at step S1 and ends at step S10. Those skilled in the art will appreciate that the division of these steps is exemplary and one or more of these steps may be decomposed into one or more sub-steps, or several steps may be combined into one step.

[0037] The method is described with reference to a passenger P with one of the aforementioned visual impairments. It is assumed that the passenger P is already on a floor L, L1 and is within the effective range of the activation device 6 arranged there; the passenger P moves to the activation device 6, for example, with the aid of the aforementioned tone signal and / or the blind guidance system, because the passenger wants to be transported from this floor L, L1 to a target floor L, L1 by means of an elevator. Figure 1As shown in FIG, the elevator operating device 4 is arranged close to the activation device 6. The elevator system 1 is equipped with a destination call controller, corresponding to which the operating interface of the elevator operating device 4 displays, for example, an input field for the number of the destination floor and, if necessary, also relevant floor-specific information. The elevator operating device 4 is in normal operating mode, which Figure 3 In another diagram of the flow chart, step S2 may also be omitted.

[0038] If the passenger P operates the activation device 6, in particular the activation device 38 thereof, the radio device 7 transmits an activation signal. In step S3, the activation signal is received by the radio device 5 of the elevator operating device 4. In one embodiment, the activation signal can be coded and / or include an identifier so that the elevator operating device 4 can clearly recognize that the received activation signal originates from the adjacently arranged activation device 6 and not from another Bluetooth transmitter.

[0039] In response to the received activation signal, the elevator operating device 4 switches from the normal operating mode to the special operating mode in step S4. In one embodiment, the audio device 9 can be activated for voice output and voice input in the special operating mode. In another embodiment, in addition to or instead of the audio device 9, the touch screen 11 can be activated for word recognition and / or gesture recognition.

[0040] In the special operating mode, the elevator operating device 4 executes a procedure for operator guidance in step S5. The operator guidance may include, for example, the audio device 9 greeting the passenger P using one or more (stored) voice messages, informing them of their location and asking them to state the desired destination floor as a number or floor-specific information (e.g., restaurant, parking lot, entrance hall). The audio device 9 may be equipped with a voice recognition module for this voice input. The voice message generated by the audio device 9 may inform the passenger P of the recognized destination floor and ask them to confirm or repeat the destination floor.

[0041] In one embodiment, the audio device 9 can generate a voice message that speaks the floors that can be reached from the current floor, and the passenger P can respond at the desired destination floor, for example, by speaking "stop," "stop," or similar words. In conjunction with this voice message, the touch screen 11 can be controlled in the following manner so that the currently announced floor is displayed and the passenger P is asked to touch the touch screen 11 at the desired destination floor.

[0042] In one embodiment, the voice message can request the passenger P to present proof of authorization. The proof of authorization can be designed, for example, in the form of a card-like carrier with an integrated RFID transponder or an optical code (e.g., a barcode or QR code) displayed thereon. The voice message can also indicate where on the elevator operating device 4 the proof of authorization is to be presented. Based on the proof of authorization, a destination call to the determined destination floor can be triggered.

[0043] In one embodiment, the operating instructions may include the audio device 9 instructing the passenger P to touch the touch screen 11 and write the number of the desired destination floor or floor-specific information (e.g., restaurant) with his finger. The touch screen 11 or the processor 28 controlling the touch screen and / or the central control unit 32 are designed for such character or text recognition. A voice message generated by the audio device 9 may inform the passenger P of the recognized destination floor and request confirmation or a new entry.

[0044] In step S6, a check is performed to determine whether the call input has ended. In one embodiment, the call input is considered to have ended when passenger P confirms the voice or character input recognized and issued by audio device 9. In this case, the method proceeds to step S7 along the "Yes" branch; otherwise, the method returns to step S5 along the "No" branch.

[0045] In step S7, a destination call is transmitted from the elevator operating device 4 to the elevator controller 13. When a destination call is received, information about the landing floor and the destination floor is obtained so that the allocation algorithm can use this information to select and allocate a car 10 for the trip. Figure 1 In the illustrated embodiment, a destination call controller 12 receives a destination call. Such an allocation algorithm is known to those skilled in the art, for example, from EP 1 276 691 B1. Those skilled in the art will recognize that, depending on the design of the elevator system 1, the allocation algorithm can also be run taking into account floor-side elevator operating devices 4, as described, for example, in EP 1 276 691 B1. The determined elevator car 10 is transmitted to the elevator operating device as travel information 4. Depending on the configuration of the elevator system 1, the travel information may include additional information, such as when the car 10 is expected to arrive at the floor. The elevator controller 8, for example, primarily controls the drive 14 so that the allocated car 10 travels according to the destination call.

[0046] In step S8, the travel information is transmitted to the passenger P via the elevator operating device 4. For this purpose, the audio device 9 can generate a corresponding voice message. Depending on the elevator system 1 and the building, the voice message can also include path or direction information (e.g., left, right). The elevator operating device 4 can be designed so that the communication of the travel information of the passenger P is repeated automatically or on demand.

[0047] In step S9, the elevator operating device 4 switches from the special operating mode back to the normal operating mode. In one embodiment, the switch is performed after the determined time period has expired after the driving information is transmitted in step S8. The method ends in step S10.
