Definitions

  • the invention is based on a hazard warning device with variable optical display of symbols and / or text.
  • the invention also provides a method and a use and a vehicle device.
  • Mobile visual warning devices such as mobile variable traffic signs or with lighting technology, e.g. LED or lamps, equipped traffic signs to warn against dangers are in use today.
  • a transmitting / receiving unit is mobile carried in a motor vehicle and a second transmitting / receiving unit is stationarily arranged at a traffic sign.
  • the information of the stationary unit can be variably programmed externally.
  • a breakdown warning sign is known, which is configured to send information to a vehicle, where this information is converted into sound signals when entering the danger zone.
  • a hazard warning device with variable optical display of symbols and / or text and a radio interface, which is set up to transmit meaningful information by radio to vehicles in synchronism with the preselected optical display, a freely selectable additional information in the form of symbols and / or text can be displayed in addition to the function of a standard traffic sign and meaningful information is transmitted to vehicles.
  • the hazard warning device according to the invention can be quickly set up and retrofitted. It is particularly suitable for mobile use, eg. B. on construction sites or as equipment of police vehicles. It can be set up quickly and, in particular, enable a much earlier transmission of the information / warning via a C2X function.
  • a use of stationary variable traffic signs systems, z. B. to gantries, is also possible.
  • the setting can be made here from a central station.
  • the warning device it is advantageous to set up the warning device so that its position is transmitted via the radio interface.
  • the receiving vehicles themselves can determine whether the information transmitted is relevant to them, eg. B. Oncoming lane on the highway.
  • the hazard warning device in the form of an input device with a memory and a selection control, which is designed such that when it is actuated from the memory both information for visual display and meaningful information about the radio interface can be output, there can be no discrepancies between optical display and radio transmitted information come. There is a synchronous adjustment between optical display and radio transmission.
  • the hazard warning device can be activated as a traffic sign, optionally with additional display, z. B. for current traffic-related information.
  • the hazard warning device is set up to adjust the transmitter radius and / or sector. This prevents, on the one hand, unnecessary attention in vehicles for which the information is not important and also contributes to increasing the service life of the hazard warning device, in particular during battery operation (no unnecessary waste of transmission energy).
  • both a preselected visual display of symbols and / or text as well as synchronously to this display transmit meaningful information to a radio interface for transmission to vehicles.
  • Networked units make it very quick and safe to change the displayed information, since all the danger warning devices present in the networked system are matched with respect to both their visual display and their transmitted information.
  • Such networking is particularly advantageous in the field of construction sites and also reduces dangerous work on highways and highways.
  • an inventive hazard warning device 1 consists of a compact mobile system unit with a display panel 2 for the variable display of pre-stored symbols, which may be traffic signs or other hazard warning symbols, a text box 3 for the display of texts, an externally accessible manual input device 4 and a radio interface 5 in the form of an antenna.
  • the display 2 can z. B. consist of LEDs or lamps as well as the text box 3.
  • a memory 6 is provided which outputs via a selection control 7 stored selectable symbols and associated stored texts to the display panel 2 and optionally also to the text field 3. This can be z. For example, a warning triangle with text box display "control".
  • the display information is forwarded to a transmitting unit 8, which converts this information into radio signals and forwards it to a radio interface 5 in the form of an antenna.
  • the transmitter radius or sector can be set by controlling the antenna or the transmitter amplifier.
  • the display in the fields 2 and 3 is variable, depending on the input via the input device 4 and processed by the selection control 7 selection commands.
  • the input device 4 via a corresponding keypad also directly selectable text information to the text box 3, especially when information is to be displayed, not preset in the memory 6 be available.
  • the radio interface 5 is equipped with a radio receiving unit 10.
  • the selection commands transmitted by the center are directed to the selection control 7 and can also be entered permanently in the memory area of the memory 6. Via an integrated (D) GPS receiver 11, the position of the hazard warning device 1 can be transmitted via the radio interface 5 together with the warning information.
  • FIG. 3 shows another example of a hazard warning display.
  • the display panel 2 shows symbolically motor vehicles that are to be classified on a track.
  • the text field 3 shows the text "Zipper in 300 m".
  • Other examples of the display for the text box may be Accident, Jam, Hold Right, Check, Aquaplaning, Oil Track, or even arrow icons for a recommended direction.
  • the transmission of the information transmitted via the radio interface 5 is preferably via C2X.
  • Corresponding devices for receiving and outputting the received information in acoustic and / or graphic form are then necessary in the vehicles.
  • the output of the information can also be on existing devices, eg. B. display or voice output of a navigation device, done. Via the navigation device, the relevant information can also be filtered out on the basis of the transmitted position of the hazard warning device.
  • the hazard warning device of the invention may be operated as part of a networked system with a coordinated rapid and secure change of the displayed and transmitted information.
  • the hazard warning device can be mounted on vehicles, eg. As to heavy goods transport or police vehicles. It is also suitable as a component of a stationary variable traffic sign system (eg sign bridge) with attitude and change by a central office.
  • vehicles eg. As to heavy goods transport or police vehicles. It is also suitable as a component of a stationary variable traffic sign system (eg sign bridge) with attitude and change by a central office.
  • stationary variable traffic sign system eg sign bridge
