Definitions

  • the invention relates to an RDS receiver for the evaluation of Traffic information, with the features of the preamble of claim 1.
  • the Traffic Message Channel is provided in the RDS specifications is used to transmit traffic information. Because a total of a lot of TMC messages for a large area is broadcast by the RDS stations there is a need to determine the approximate location of the RDS receiver to determine and the RDS receiver for the evaluation of the To provide TMC messages. This makes it possible for the to provide relevant traffic information for each location.
  • the object of the present invention is therefore to provide an RDS receiver for Specify evaluation of traffic information, in which a manual entry of the Location is not required.
  • the advantage of the invention is in particular that the location is automatic is determined, making manual entries unnecessary.
  • the single figure shows a block diagram of an inventive RDS receiver for the evaluation of traffic information.
  • the figure shows an RDS receiver 2 by a tuner and a RDS decoder is formed, which is connected to an antenna 1.
  • a control device 3 for example, by a Microcomputer can be formed, connected to a memory 4.
  • a device for determining position 5 the can optionally be connected to the control device 3.
  • Radio signals are received by the RDS receiver 2 via the antenna 1, that contain RDS information.
  • the RDS information is from the RDS receiver 2 contained RDS decoder decoded.
  • the RDS decoder also decodes the TMC messages.
  • the TMC messages contain in addition the type of traffic information, e.g. B. 10 km traffic jam, also information about the place for which the traffic information is intended.
  • the decoded TMC messages are forwarded by the RDS receiver 2 to the connected control unit 3.
  • the control unit 3 uses the location information to generate the TMC message checks whether the present TMC message for the current location of the RDS receiver 2 is important.
  • the location information of the TMC message with information stored in the memory 4 about the current location of the RDS receiver 2 compared by the control unit 3.
  • the message is important, it is indicated by an optical and / or acoustic Output unit of the RDS receiver 2, or in a memory, for example the memory 4.
  • a user can click on such access stored traffic reports at any time and get a quick Gain an overview of the traffic situation in his area.
  • a device for determining the current position evaluates the receivable broadcast signals.
  • the RDS decoder originating RDS information such as the transmitter identification from the control unit 3 evaluated, which allow a conclusion to the currently receivable transmitter.
  • the respective location can be determined relatively precisely with RDS information.
  • the received stations with RDS information are included in the on the control unit 3 connected memory 4 stored table, from which shows which stations with RDS information in which areas received, compared. The location determined in this way becomes as above described, stored in memory 4.
  • the RDS receiver 2 To include all receivable stations To be able to evaluate RDS information, the RDS receiver 2 must either have two tuners and possibly two RDS decoders or a tuner that briefly and inaudibly while receiving a station on other stations can vote to evaluate the required RDS information. Otherwise there are disruptions in the audio playback of the Program of the station selected for reception.
  • the field strength of the or the received radio signals can be determined by the control unit 3.
  • the level of the received signals is digitized by a D / A converter to be able to be processed in the control unit 3.
  • Im to the control unit 3 connected memory 4 are tables for the location determination Field strength information for the transmission areas of the respective transmitters filed. Because of of the transmitter determined by means of the transmitter identification can then by means of the Evaluation of the reception field strength determines the respective location more precisely will.
  • the determined location is stored in memory 4 as described above.
  • Another device for determining the position can be from a Navigation system, for example one that works according to the GPS standard Establishment. Such a device for position determination 5 is shown in the figure.
  • the location determined by the position determination device 5 is then as described above, stored by the control device 3 in the memory 4 and for the selection of the TMC messages used by the control unit 3.
  • the location is determined by means of device 5 or as described above RDS information and / or reception field strengths should at least always follow the RDS receiver 2 is switched on. Is the RDS receiver in one Motor vehicle installed, the location should also after switching on of the RDS receiver 2 or after switching on the ignition of the motor vehicle be determined continuously, at certain time intervals.
