Definitions

  • the invention relates to the field of route guidance for people, in particular escape route guidance.
  • a display device for buildings and a corresponding wayfinding system and an arrangement which includes the wayfinding system and a sensor network are proposed.
  • Safety lighting with emergency lights enables people to leave a building or area quickly and safely in an emergency situation, such as a fire, or to access safe areas of the building.
  • Escape route signs with pictograms are arranged in appropriately equipped buildings or areas, which are intended to provide spatial escape route guidance in the event of such an emergency situation. Escape route signs should also be visible in the event of a fault in the general electrical lighting of the building and are therefore often designed to be integrated with emergency lights.
  • escape route signs are signs with pictograms or special escape route indicator lights that show people the direction of an escape or rescue route to leave the building or area.
  • the pictograms can be applied to signs as static escape route displays.
  • Escape route indicator lights may include illuminated pictograms that are activated as active escape route indicators upon the occurrence (detection) of an emergency event.
  • Pictograms as displays are pictorial representations of information showing a stylized person running and an arrow pointing in the direction of a predetermined escape route.
  • the pictograms can include other characters, for example the words “EXIT”.
  • Dynamic escape route displays have therefore been developed in which some of the escape route displays are designed as a changeable display. With these changeable displays, an arrow is shown in the direction of the escape and rescue route, with the direction of the arrow being indicated by corresponding Control of the display is adjustable. Such a dynamic escape route display can be controlled, for example, depending on the data from fire alarms collected in a fire alarm control panel (BMZ) of the building.
  • BMZ fire alarm control panel
  • a display device having the features according to claim 1, a wayfinding system and an arrangement of a wayfinding system and a sensor network according to the independent claims.
  • the invention relates to a display device that includes an optical display unit and a housing frame.
  • the visual display unit is designed to display a pictogram.
  • the display device is characterized in that the optical display unit is mounted elastically on the housing frame and can be excited to mechanical vibrations relative to the housing frame.
  • the display device according to the invention has a vibration-generating means.
  • the vibration-generating means is designed, on the basis of a control signal, to excite the optical display unit to perform mechanical vibrations for the reproduction of an acoustic signal in a frequency range that can be heard by humans.
  • the acoustic signal output is directly integrated in the display device according to the invention. It is particularly advantageous with regard to the structure of the display device to use the optical display unit for the visual display of the pictogram at the same time as an acoustic signal transmitter, in particular as its sound surface. A loudspeaker as an isolated component can thus be dispensed with. Optical and acoustic escape route guidance are also particularly advantageously integrated in a single display device.
  • the display device makes it possible to implement a system for dynamic escape route guidance in such a way that a dynamic, optically perceptible emergency exit sign and a dynamic acoustic escape route guidance are provided in combination.
  • a system for dynamic escape route guidance in such a way that a dynamic, optically perceptible emergency exit sign and a dynamic acoustic escape route guidance are provided in combination.
  • the display device brings about reduced manufacturing costs for the manufacturer and reduced procurement costs and system costs for the customer.
  • a product display device implements both functions - optical display and acoustic display of corresponding information -, which means that fewer components have to be procured for a wayfinding system with the same functionality, to be installed and to be integrated into a system.
  • the structure of the display device itself is particularly advantageous because the optical display unit component for providing two functions—optical display and acoustic display of corresponding information—takes on essential tasks.
  • the optical display unit is used directly for the visual display of the pictogram, at the same time the function of a loudspeaker membrane is taken over for the acoustic output of the acoustic signal.
  • the display device has a control unit for generating and outputting a control signal to the vibration-generating means of the display device.
  • the display device can thus use the optical display unit as a membrane of a sound converter, which generates an acoustic sound signal in a frequency range perceptible to people from the supplied (electrical) control signal and emits it to the environment.
  • the arrangement of the control unit in the display device simultaneously enables local control and coordinated control of the output of optical and acoustic information at one position.
  • the display device comprises storage means set up for storing at least one predefined acoustic signal assigned to the pictogram.
  • the acoustic signal can be stored as a control signal for output to the vibration-generating means.
  • the display device has an interface designed for reading in the predefined acoustic signal assigned to the pictogram.
  • the control unit of the display device is set up to output the stored and/or read-in predefined acoustic signal to the vibration-generating means as a function of a spatial position of the display device and/or depending on the situation in the control signal, and to visibly display the associated pictogram through the optical display device.
  • the display device in a further embodiment comprises the control unit, which is set up to control the vibration-generating means with the control signal at least in a first operating mode for the acoustic reproduction of a voice and/or music signal, and in a second operating mode with the control signal for an acoustic output of the acoustic signal assigned to the pictogram and at the same time to bring about a visual output of the pictogram via the visual display unit.
  • the display device comprises the control unit set up to activate the vibration-generating means in the first operating mode if the control unit detects operation of the display device in mains operation, ie powered by a mains power supply.
  • the control unit is also designed to control the vibration-generating means in the second operating mode when the control unit detects mains-independent, battery-supported operation of the display device. Battery-supported operation is therefore evaluated as an indication of a failure of the mains power supply and thus also as an indication of the occurrence of an emergency event.
  • the control unit can be set up to switch between the first operating mode and the second operating mode on the basis of a signal supplied externally to the display device. This can be done, for example, by means of an activation signal fed via a DALI interface to the display device, in particular to its control unit.
  • the display device can comprise a magnet as the vibration-generating means and an electromagnet supplied with the control signal.
  • the optical display unit has a flat display carrier and a lighting means arranged parallel thereto.
  • the lighting means is designed as a light guide, preferably as a light guide plate, and is arranged in front of the display carrier in the viewing direction in order to enable front lighting of the display carrier.
  • the display carrier illuminated by the lighting means shows the pictogram in the viewing direction without the components of the display device causing a disturbing formation of shadows.
  • the display device of a further embodiment uses electronic paper as the display technology for the visual display unit in order to display the pictogram in a visible manner.
  • the pictogram preferably represents dynamically and/or adaptively changeable path information and/or direction information.
  • Electronic paper as the display technology enables the realization of a dynamic display of the pictogram.
  • Electronic paper also sometimes referred to with the English translation "E-Paper Display”, the terms “E-Ink”, “eInk” or “E Ink TM “ used synonymously, as a display technology for screens, achieves that a dynamic display is created, which continues to display a set figure even if one of the power supply fails completely.
  • electronic paper is an example of a bistable display that requires energy input in the form of an electrical current just to change the display. This is particularly advantageous for battery-backed operation in the event of an emergency event involving failure of a mains power supply.
  • Electronic paper has the further advantage that the display realized in this way shows the essential properties of classic signage. Existing standards and recommendations for the appearance of safety displays can be easily met using this type of display. This also applies in particular to a color display. Due to a small distance between the imaging elements and the surface of the optical display unit, the displayed display content looks the same from a wide viewing angle range and is easily recognizable. The content of the visual display is shown flicker-free and is equally in artificial light, so for example a lit room, or sunlight visible. Electronic paper is available in various sizes, thin in thickness and therefore light in weight to manufacture, and can be formed into flexible and rigid designs. due to the low weight and the associated low mass inertia, such a display unit is particularly suitable for the display device according to the invention.
  • the display device of a preferred embodiment is designed as an escape route display.
  • the display device With its ability to output information both acoustically and visually, the display device is particularly suitable for operation when emergency events occur using the “two-senses principle”. People in stressful situations are reliably provided with essential information via their visual and acoustic senses. An acoustic output by the same device that also represents the visual display has the advantage that people's attention is drawn in the direction of the display. This uses the fact that humans can locate a direction in space to a sound source.
  • the invention relates to a wayfinding system with at least one display device according to the first aspect of the invention.
  • the at least one display device is distributed in a spatial area and networked by means of a communication network of the wayfinding system.
  • a control device of the wayfinding system is set up to control the at least one display device individually to output a position-related acoustic signal and the correspondingly assigned pictogram.
  • the display device thus makes it possible to design a particularly advantageous wayfinding system, since the acoustic signals are provided exactly where they are needed in order to implement dynamic acoustic wayfinding: at each designated change in route.
  • dynamic announcements such as "go left”, “go right” can thereby be provided to people where they are most appropriate.
  • the invention relates to an arrangement comprising the wayfinding system according to the second aspect and a sensor system, wherein the wayfinding system and the sensors of the sensor system over the spatial area are distributed.
  • the control device has an interface that is set up to read in position-related sensor data.

  • control unit 13 can check whether the display device 1 is being fed by the mains power supply 14 in mains operation, or whether the mains power supply 14 has failed and the display device 1 is battery-supported and therefore mains-independent. If mains-independent, battery-supported operation of the display device 1 is present, then the control unit 13 decides that the building needs to be cleared and that an evacuation event is therefore present.

  • step S2 If the control device 13 decides in step S2 that an evacuation event has occurred, the control device 13 can determine the specific evacuation event in step S3. For the application of dynamic routing, this can mean, for example, determining whether the display device 1 should display a specific pictogram 19 for the present evacuation event and output a specific acoustic signal assigned to the pictogram 19 .
  • the control device 13 now continues with step S4 and with the action of the display device 1 specified for the specific evacuation event.

  • step S5 the control unit 13 generates the control signal 15 on the basis of the acoustic data read in and sends this control signal to the vibration-generating means.
  • step S5 the display device 1 now works in the second operating mode, in which at the same time as the optical output Pictogram 19 corresponding to the read-in image data on the display medium 5, the acoustic output of the pictogram 19 assigned acoustic signal 20 by means of corresponding vibrational excitation of the optical display unit 4 takes place.
  • the display device 1 thus implements a “dual mode” operation.
  • the display device 1 can also be used as a purely acoustic reproduction means in one of the operating modes.
  • the control device 37 can have an interface 37.2 via which data for the acoustic output, in particular music data and/or voice data, can be read.
  • the read-in data can be processed in the control device 37 .
  • the processed data can be forwarded via the communication network 38 to the individual display devices 31 to 35 for the acoustic output. This means that the separate and additional construction of a network for additional loudspeakers for the output of acoustic signals is just as unnecessary as additional loudspeakers for the display devices 31 to 35.
  • the first operating mode enables the creation of a distributed loudspeaker system, which is made possible with minimal additional effort in the area of the emergency light control unit 36 and the control device 37 by means of the display devices 1, 31 to 35 according to the invention. Since escape route lights are located at every exit door (escape route) around the room in a hall-like room, the room can be exposed to sound from different sides. An effect comparable to “Dolby Surround” can thus be achieved by including the display device according to the invention in a system for sound reinforcement of the room. The technical outlay and thus the combined costs for escape route identification and guidance and sound reinforcement of the room are thus advantageously reduced by means of the display device 1 according to the invention.
