The utility model discloses a
wireless radio
station voice network transfer device without a central
server, and belongs to the technical field of
wireless communication. The device comprises
terminal equipment (a radio
station / radio
station hand
microphone), an audio
processing unit (an audio interface unit and an audio interface
control unit), a core
processing unit (DSP), a network interaction unit, a
power supply unit and an optional voice synthesis
processing unit (TTS). The
terminal equipment collects voice signals, the format of the voice signals is converted through the audio processing unit, the DSP carries out coding compression, and the voice signals are accessed to an office
intranet and other networks through the network interaction unit to achieve cross-regional transmission. All the units are connected through standardized lines such as SP / MIC / Ai / Ao, a decentralized architecture is adopted, and voice
unicast, broadcast and
multicast transfer can be achieved without a central
server. The device has the advantages of being high in reliability, flexible in networking, low in cost, efficient in processing, high in compatibility (adaptive to various radio stations) and the like, and is suitable for cross-regional communication scenes such as railway centralized operation command,
emergency rescue and the like.
