Direction-based interface selection method
The invention relates to a direction-based interface selection method, carried out by a communication control module ( 8 ) in a vehicle ( 1 ), for establishing and retaining a wireless high-frequency communication connection between a communication interface of a moving vehicle ( 1 ) and a communication interface of at least one counterpart station. In this case, position data and an orientation of the vehicle with respect to a global coordinate system are determined. A position data record is determined by at least one counterpart station and the position data ( 12 ) contained therein are extracted. A direction vector ( 13 ) from the vehicle ( 1 ) to the counterpart station is then determined and an assignment to a sectoral radiation characteristic of a transmission apparatus is determined for said vector. This transmission apparatus is then connected to a communication device ( 7 ) via a communication position switch ( 6 ).
1. A vehicle in particular a water-borne vehicle or
aircraft, comprising a wireless high-frequency communication interface, and a communication interface connected thereto, characterized in that
the high-frequency communication interface has four transmission devices, which transmission devices each have a sectoral radiation characteristic, which radiation characteristic corresponds to a sub-region of the space around the vehicle, the radiation characteristic of each transmission device covering an azimuthal sub-range between 85° and 100°, in particular between 90° and 95°, and in that
each transmission device has a high-frequency unit and an antenna, and wherein each transmission device is connected via a communication path switch to the communication device, and in that
the communication path switch is connected to a communication control module, which is designed for selectively connecting the communication device to a transmission device by means of the communication path switch, and in that
a receiving device connected to the communication control module is provided, which is designed to receive message packets of an automated identification system, and in that
the communication control module has an evaluation module, which forms a direction vector from position data of the vehicle and from position data which were extracted from received message packets, and in that
the direction vector with
based on the selection value, the communication path switch specifies a communication path between the communication device and one of the transmission devices.
2. The vehicle as claimed in claim 1 , characterized in that each transmission device also has a receiving device.
3. The vehicle as claimed in claim 1 , characterized in that an automated identification system is present on the vehicle, which is designed for the cyclical transmission of identification message packets.
4. The vehicle as claimed claim 1 , characterized in that a receiver for a global satellite navigation system is present on the vehicle, which receiver provides position data of the vehicle.
