Definitions

  • the invention relates to a data transmission device for traffic control and traffic information systems the preamble of claim 1.
  • a traffic control system in which Guiding information about vehicles are transmitted.
  • the infrastructure for such a traffic information system can be created with as little effort as possible by for example existing traffic signal calculator for Light signaling controls can also be used. Therefore is proposed, in addition to a light signal transmitter, a Transmitting and receiving device, a so-called beacon, on the light signal mast attach what with effort and connection work and costs are connected. They are also different Techniques for operating the light signal transmitter and the transmitter and Receiving facilities necessary.
  • Colored light is conventionally used in light signal transmitters generated a light bulb in front of a colored filter plate is arranged.
  • the effect is known that due to the Light conditions in the area the colored filter plate Even when the light bulb is switched off, it seems to light up it is not clear whether the corresponding signal is or is switched off.
  • Another disadvantage of using it of incandescent lamps is that these light in one emit broadband radiation spectrum and only a small one Filtered out percentage in the desired color and thereby only a fraction of the energy used becomes.
  • the object of the invention is a data transmission device to develop in traffic lights, both as traffic lights as well as for the transmission of data control technology for both functions Current pulses used in the high frequency range.
  • the task is carried out in a data transmission device initially mentioned type solved according to the invention in that an LED matrix is used as the signal unit, with the characterizing features of claim 1.
  • the group of light emitting diodes emitting in the visible range and the group of those emitting in the infrared range LEDs can be controlled separately.
  • An advantage this arrangement compared to the conventional realization of Signal generators with unpulsed or low-frequency power supply and transmitters with high-frequency control is the now possible common operating technology, since both types operated by diodes with current pulses in the high frequency range become.
  • the light output emitted in the visible range is easier to control while the pulses the diodes emitting in the infrared range for information transmission can be encoded.
  • the invention can transfer the data from the central traffic computer to the transmitter unit via cable, by infrared transmission or done by radio transmission.
  • the yellow light of a red-yellow-green light signal transmitter through a light-emitting diode matrix made of yellow-emitting light-emitting diodes and infrared diodes are formed.
  • a light-emitting diode matrix made of yellow-emitting light-emitting diodes and infrared diodes are formed.
  • FIG 1 shows the front view of a red-yellow-green light signal transmitter LS.
  • Red light RL and green light GL are included realized as known by an incandescent lamp with a filter disc and shown only schematically.
  • the yellow light consists of a light emitting diode matrix made up of a large number Light emitting diodes SIL (typically 300 - 500) and a number Infrared light emitting diodes IRL (typically 60-100).
  • FIG. 2 shows schematically in cross section that the yellow emitting light emitting diodes SIL together to an electronic Control ES are connected via a control unit SE is connected to a traffic control center VLZ. Red light RL and green light GL are also via the control unit SE connected to the traffic control center VLZ.
  • the in Infrared emitting diodes IRL are with another Control IS connected, which in turn via data lines DL is connected to the control unit SE and to be sent Signals from the traffic control center VLZ transmitted gets.
  • FIG. 3 shows schematically in cross section as in the embodiment 2 the transmission of data from the control unit SE to the further control IS in the infrared range emitting diodes executed by wireless transmission becomes.
  • both the further control IS with a Transmitting and receiving unit SIS as well as the control unit SE connected to a further transmitting and receiving unit SSE.
  • Both sending and receiving units can now either Communicate with each other via radio or infrared transmission.
  • FIG. 4 the embodiment according to FIG. 3 has been expanded so that that additional photodiodes PD in the light-emitting diode matrix are integrated, which receive signals from the vehicles can and via an additional control PS and the transmission and receiving unit SIS with the control unit SE and thus the traffic control center VLZ.
