Definitions

  • the invention relates to a method for carrying out a wireless data exchange between a base station and Transceivers on board relative to the base station preferably in moving objects, in particular Vehicles, using an antenna arrangement with several Antennas, the reception profiles of which are electronic a vehicle can be aligned, the transceivers a response signal to a received signal with the same carrier frequency send out, whose level is proportional to the level of the received signal.
  • the invention further relates to a device for performing of the procedure.
  • a method of the type mentioned at the outset is from DE 41 07 803 Al known.
  • Query arrangement is automatic payment of toll fees listed. Any vehicle that has to pay a toll fee has an automatic debit facility, with the transceiver on board the vehicle cooperates. Between the base station and the transceiver there is a data exchange. Posted first the debiting facility sends the toll fee and sends then a receipt to the base station. While this process is carried out with antenna elements of the antennas Base station for the vehicle in question a reception profile generated. The reception profile can possibly be the moving one Vehicle to be tracked.
  • the transceivers on board of the vehicles expediently work as transponders send the received signal back in modulated form. Accordingly the response signal has the same carrier frequency as that signal emitted by the base station. Beyond that its level proportional to the level of the received signal.
  • the Receiving antenna be designed so that e.g. just a vehicle stay within the associated illumination area can.
  • the alignment properties of the receiving antenna must ensure that there is strong attenuation of signals outside the desired footprint is made to an incorrect one Avoid assigning signals from neighboring vehicles.
  • a reduction in signals required in practice outside the main lobe of the antenna is, for example -40dB.
  • the receiving antenna In order to achieve this attenuation value, the receiving antenna must formed with a large number of antenna elements be, so that a considerable effort is required.
  • an antenna (5) comprises a receiving antenna part (7) and a transmitting antenna part (6) associated therewith, and in that each receiving antenna a transmitting antenna is assigned and that the transmitting antenna Signals with a reception profile of the reception antenna sends the corresponding broadcast profile.
  • the side lobe damping exclusively through the reception profile of the reception antenna is effected and wide-beam, that is, multiple vehicles Transmitting antennas are provided in the invention
  • a plurality of transmission antennas are provided, who send out their signals with a transmission profile that corresponds to the reception profile of an associated reception antenna. Since also the transceivers on board from others potentially disruptive moving objects the emitted signals send back according to the transponder principle, are by the Send profile already heavily attenuated signals with the result resulting low signal level sent back to the base station and attenuated again by the reception profile, so that the Multiply the attenuation of the transmission profile and reception profile. If the transmission profile and reception profile match, for example the attenuation value of -40dB is reached that the corresponding side lobe damping with transmission profile and with reception profile is in each case -20dB. These damping values can be realized with much simpler antenna arrangements.
  • the problem underlying the invention is further solved with a Device for performing the method solved at in the base station of each receiving antenna is a transmitting antenna is assigned and receiving antenna and transmitting antenna each have a steel forming network. It is special advantageous if transmit and receive antennas assigned to each other arranged in the immediate vicinity are and the beam forming networks of the associated Antennas are controlled by the same processor.
  • Figure 1 shows vehicles 1, each with a transceiver 2 are equipped and in front of a base station 3 are located, the lanes 4 of a street spanned like a bridge.
  • the base station has an antenna arrangement with several Antennas 5, 4 for example for each lane a transmitting and receiving antenna 5 is provided.
  • FIG. 2 Communication between base station 3 and the vehicle 1 is illustrated in FIG. 2.
  • the transceiver 2 of the vehicle 1 are activated.
  • data from the base station 3 on the Transfer vehicle in particular the debiting of a fee amount caused by the transceiver 2.
  • FIG 3 shows the schematic structure of an antenna 5 their transmitting part 6 and receiving part 7.
  • the transmitting part 6 contains a plurality of transmit antenna elements 8, which over a Beam shaping network 9 with the output signal of a transmitter 10 are supplied via a distribution circuit 11.
  • Beam shaping network 9 will be the individual on the spatial distributed transmit antenna elements 8 routed signals weighted differently, setting the weighting is made by a processor 12. Because of the different vectorial weighting creates a send profile of the transmitting part 6 of the antenna 5.
  • the receiving part 7 of the antenna 5 has a A plurality of receiving antenna elements 13, which over a Beamforming network 14 and a summer 15 with one Receiver 16 are connected. Because of the same processor 12 controlled weighting within the beamforming network 14 shows a spatial sensitivity distribution in Form of a reception profile.
  • an evaluation circuit 17 connected to a series of Information 20 can be created by processor 12 for creation suitable transmission and reception profiles can be used.
  • the processor 12 can also provide information, for example, about the weight distribution of beam shaping networks 9, 14 of neighboring ones Received antennas 5.
  • Figure 4 shows two adjacent antennas 5, 5 'of a base station 3. These communicate with two transceivers 2, 2 'in vehicles 1.
  • the antennas 5, 5' each define one Illumination area 18, 18 'in the form of a main lobe, the Main lobes of the transmitting parts 6 and the receiving parts 7 are identical are and multiply in their effect.
  • the directivity the transceiver 2, 2 ' is small to a desirable Freedom to attach the transceivers 2, 2 'to ensure in vehicles 1.
