Abstract

The invention relates to a communications system (10, 110) for an aircraft comprising a transceiver (22) having at least one transmitter (24), at least one receiver (26, 28) and at least one antenna, at least one data processing device (12) connected to the transceiver (22) by means of a data transfer device (20) and having at least one operating device (14), connected to the at least one data processing device (12), having manually activated switches, buttons and/or rotary knobs (18) for entering data into the at least one data processing device (12). According to the invention, the at least one operating device (14) is mechanically connected to the at least one data processing device (12) to form an assembly (16).

Claims

1-11. -11. (canceled)

12. Communications system for an aircraft, having a transmission and reception device (22) having at least one transmitter (24), at least one receiver (26, 28), and at least one antenna, having at least one data processing device (12) connected with the transmission and reception device (22) by means of a data transmission device (20) for transmission of audio data, and having at least one operating device (14) having manually activated switches, buttons and/or knobs (18), connected with the at least one data processing device (12), for input of data into the at least one data processing device (12), wherein the at least one operating device (14) is mechanically and releasably connected with the at least one data processing device (12), to form a modular unit (16) and wherein electrical components of the at least one operating device (14) are connected with electrical components of the at least one data processing device (12) by means of an electrical plug-in connection.

13. Communications system according to claim 12, comprising multiple operating devices (14) and multiple data processing devices (12), wherein the number of data processing devices (12) is at least as great as the number of operating devices (14), and wherein a data processing device (12) that can be operated by means of the operating device (14) is mechanically connected with each operating device (14), to form a modular unit (16).

14. Communications system according to claim 13, wherein all the data processing devices (12) have the same construction.

15. Communications system according to claim 14, wherein the electrical plug-in connections are configured with the same construction, as standard plug-in connections.

16. Communications system according to claim 13, wherein at least one of the operating devices (14) is connected, by way of the data processing device (12) that is connected with it, with a further data processing device (12) that can be operated by it, by means of the data transmission device (20).

17. Communications system according to claim 13, wherein all the data processing devices (12) are connected with one another by means of the data transmission device (20).

18. Communications system according to claim 17, wherein audio data can be transmitted between the data processing devices (12), by means of the data transmission device (20).

19. Communications system according to claim 13, wherein at least one of the and preferably each of the data processing devices (12) is connected with at least one transmitter (24) and at least one receiver (26, 28), by means of an analog two-wire line (32), in each instance.

20. Method for transmission of audio data between two data processing devices (12) and/or between a data processing device (12) and a transmitter (24) or receiver (26, 28), in a communications system (10, 110) according to claim 12, wherein a signal sequence that characterizes the audio data is sampled with a sampling rate and split up into at least a first and a second partial signal sequence, wherein the signal values determined during sampling are alternately assigned to the partial signal sequences, wherein the partial signal sequences are transmitted by way of separate data lines (32), and wherein after the transmission, the signal values of the partial signal sequences are combined again to produce their original temporal sequence, to form an output signal.

21. Method according to claim 20, wherein the signal sequence that characterizes the audio data contains at least one sine oscillation and wherein the sampling rate is at least twice as great as the frequency of the at least one sine oscillation.
