The utility model provides an audio frequency annular transmission system among optic fibre seat system, includes N exchanges board, exchange board links to each other with the seat box among the seat system for data is handled and is transmitted in acquireing the seat box, its characterized in that, exchange board all is provided with independent high-speed transceiver interface, high-speed transceiver interface is used for sending or receiving data, N exchange board annular connects in order, exchange board includes:
the audio extraction module is used for acquiring a video data packet bound with audio data from an agent box connected to the mth exchange board and independently extracting the audio data from the video data packet;
the packaging and numbering module is used for arranging the audio data extracted by the mth exchange board into the same data packet and adding the number of the mth exchange board;
the sending module is used for sending the audio data packets arranged by the mth exchange board and the received audio data packets from other exchange boards to the (m + 1) th exchange board through the high-speed transceiver interface when m is more than or equal to 1 and less than or equal to N-1 or sending the audio data packets arranged by the nth exchange board and the received audio data packets from other exchange boards to the first exchange board through the high-speed transceiver interface when m is equal to N;
and the receiving module is used for receiving the audio data packets sent by other exchange boards.
8. The audio ring transmission system in a fiber optic seating system of claim 7, the switch board further comprising:
the first judgment module is used for judging whether audio data are required to be mutually transmitted through the same exchange board among different seat boxes connected to the same exchange board, and if so, the audio extraction module extracts the audio data of the different seat boxes connected to the exchange board and then carries out mutual transmission among the seat boxes according to requirements;
the second judging module is used for judging the source of the audio data packet received by the receiving module, and if the audio data packet comes from the local switchboard, the audio data packet is discarded; if the audio data packet comes from other exchange boards, the audio data packet is cached, whether the seat box connected to the exchange board needs the data in the audio data packet is judged, if yes, the corresponding audio data in the audio data packet is extracted, and the audio data is forwarded to the appointed seat box.
9. A computer device comprising a memory and a processor, the memory storing a computer program, wherein the processor implements the steps of the method of any one of claims 1 to 6 when executing the computer program.
10. A storage medium having a computer program stored thereon, the computer program, when being executed by a processor, realizing the steps of the method of any one of claims 1 to 6.
