Definitions

  • the invention relates to a method for carrying out a wireless data exchange between a base station and transmitting / receiving devices on board objects that move relative to the base station, preferably in lanes, in particular vehicles, with the aid of an antenna arrangement with a plurality of receiving antennas, the reception profiles of which can be electronically aligned to a vehicle , wherein the transceivers send a response signal with the same carrier frequency on a received signal, the level of which is proportional to the level of the received signal.
  • the invention further relates to an apparatus for performing the method.
  • a method of the type mentioned is known from DE 41 07 803 A1. Automatic payment of toll fees is listed as one possible application of the query arrangement described therein. Every vehicle that has to pay a toll fee is equipped with an automatic debit facility that interacts with the transceiver on board the vehicle. A data exchange takes place between the base station and the transceiver. The debiting facility first books the toll fee and then sends a receipt to the base station. During this process, a reception profile is generated with antenna elements of the antennas of the base station for the vehicle in question. If necessary, the reception profile can be tracked to the moving vehicle.
  • the transceivers on board the vehicles expediently work as transponders send the received signal back in modulated form. Accordingly, the response signal has the same carrier frequency as the signal transmitted by the base station. In addition, its level is proportional to the level of the received signal.
  • the reception antenna Since the assignment of vehicles and the suppression of interference signals belonging to other vehicles is achieved by the reception profile of the reception antenna, the reception antenna must be designed such that e.g. only one vehicle can stop within the associated coverage area.
  • the alignment properties of the receiving antenna must ensure that there is a strong attenuation of signals outside the desired coverage area in order to avoid incorrect assignment of the signals from neighboring vehicles.
  • a reduction of the signals outside the main lobe of the antenna that is required in practice is, for example, -40 dB.
  • the receiving antenna In order to achieve this attenuation value, the receiving antenna must be designed with a large number of antenna elements, so that considerable effort is required.
  • each receiving antenna is assigned a transmitting antenna and in that the transmitting antenna transmits signals with a transmitting profile corresponding to the receiving profile of the receiving antenna.
  • the side lobe attenuation is brought about exclusively by the reception profile of the reception antenna and broad-beam transmission antennas, that is to say which cover several vehicles, are provided
  • 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 the transceivers also send the emitted signals back on board from other potentially disruptive moving objects, using the transponder principle, signals that are already strongly attenuated are sent back to the base station with the resulting low signal level and attenuated again by the reception profile, so that the attenuations of the transmission profile and reception profile multiply.
  • the damping value of -40dB is achieved, for example, in that the corresponding sidelobe damping for the transmission profile and the reception profile is in each case -20dB.
  • the problem on which the invention is based is also solved with a device for carrying out the method, in which a transmitting antenna is assigned to each receiving antenna in the base station and the receiving antenna and transmitting antenna each have a steel forming network. It is particularly advantageous if transmitting and receiving antennas assigned to one another are arranged in the immediate vicinity of one another and the beam shaping networks of the antennas assigned to one another are controlled by the same processor.
  • the influence of interference signals can advantageously be effectively reduced by the fact that adjacent transmit antennas emit signals on different carrier frequencies and that only signals on the frequency of the assigned transmit antennas are forwarded by the associated receive antennas for evaluation.
  • FIG. 1 shows vehicles 1, each equipped with a transceiver 2 and located in front of a fixed station 3, spanning the roadways 4 of a street in a bridge-like manner.
  • the base station has an antenna arrangement with a plurality of antennas 5, a transmission and reception antenna 5 being provided for each lane 4, for example.
  • the communication between base station 3 and vehicle 1 is illustrated in FIG. 2.
  • the transceiver 2 of the vehicle 1 can be activated.
  • data is transmitted from the base station 3 to the vehicle 1, and in particular the transceiver 2 initiates the debiting of a fee amount.
  • an acknowledgment signal is then sent back from the transceiver 2 of the vehicle 1 to the base station 3, a signal with a continuous level being transmitted by the transmitting part 6 of the antenna 5 for the transmission of the acknowledgment signal is that, as a modulated signal from the transceiver 2 formed by a transponder, reaches a receiving part 7 of the antenna 5.
  • suitable measures can be initiated which enable the vehicle 1 to be identified in order to collect the charges, for example the storage of a video image of the vehicle or the like.
  • FIG. 3 shows the schematic structure of an antenna 5 with its transmitting part 6 and receiving part 7.
  • the transmitting part 6 contains a plurality of transmitting antenna elements 8, which are supplied via a beam shaping network 9 with the output signal of a transmitter 10 via a splitting circuit 11.
  • the beam shaping network 9 the individual signals directed to the spatially distributed transmit antenna elements 8 are weighted differently, the setting of the weighting being carried out by a processor 12. Due to the different vectorial weighting, a transmission profile of the transmission part 6 of the antenna 5 is created.
  • the receiving part 7 of the antenna 5 has a plurality of receiving antenna elements 13 which are connected to a receiver 16 via a beam shaping network 14 and a summer 15. Due to the weighting within the beam shaping network 14 controlled by the same processor 12, a spatial sensitivity distribution in the form of a reception profile is brought about.
  • An evaluation circuit 17 is connected to the receiver 16 and comprises a series of Can create information 20 that can be used by processor 12 to create suitable transmit and receive profiles.
  • the processor 12 can also receive information, for example, about the weight distribution of beam shaping networks 9, 14 of adjacent antennas 5.
  • the number and arrangement of the transmitting antenna elements 8 is equal to the number and arrangement of the receiving antenna elements 13.
  • the transmitting part 6 and receiving part 7 are arranged in close proximity, so that the beam shaping networks 9, 14 have the same weighting vectors from that Processor 12 received.
  • 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 an 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 and multiply in their effect.
  • the directionality of the transceivers 2, 2 ' is low in order to ensure a desirable freedom for the attachment of the transceivers 2, 2' in the vehicles 1.
