technical field

The invention relates to the field of audio transmission, and more particularly, to an audio ring transmission method, system and storage medium in an optical fiber seat system.

Background technique

The fiber optic seat system is a control room information processing solution. In the fiber optic seat system, it usually includes several switch boards connected to several seat boxes. The audio data in the seat box is usually bundled in the video data, and the audio data is transmitted together with the video data. From the agent box to the switch board, the switch board integrates various bundled data, etc., and exchanges data with other switch boards through other devices such as backplanes or transceivers to realize data exchange between different agent boxes. However, since the audio data is bundled in the video data, the audio data can only be transmitted one-to-one. For applications that require independent audio transmission, this audio transmission method cannot meet the needs, the application flexibility is insufficient, and the scalability is not strong. .

SUMMARY OF THE INVENTION

The present invention aims to overcome at least one defect (deficiency) of the above-mentioned prior art, and provides an audio ring transmission method, system and storage medium in an optical fiber seat system, which are used to achieve the independence of audio data from the binding with video data. It can realize arbitrary mutual transmission of audio data between multiple senders and receivers, improve the flexibility and scalability of the system, and increase the effect of audio data transmission bandwidth.

The technical solution adopted by the present invention is that an audio ring transmission method in an optical fiber seat system includes the following steps:

The mth switch board obtains K groups of video data packets bound with audio data from K different seat boxes connected to this switch board, and independently extracts K groups of audio data from it;

The mth switch board organizes the K groups of audio data extracted by itself into the same data packet, and adds the mth switch board number;

When 1≤m≤N-1, the mth switch board sends the audio data packets sorted by itself and the received audio data packets from other switch boards to the m+1th switch board through the high-speed transceiver interface, where N represents the number of switch boards, and N is a positive integer;

When m=N, the Nth switch board sends the audio data packets organized by itself and the received audio data packets from other switch boards to the first switch board through the high-speed transceiver interface.

In the present invention, the switch board extracts audio data independently from the video data packets bundled with audio data received by the seat box, thus realizing the separation of audio data and video data, and then the audio data of all the seat boxes connected to the same switch board are separated. The data is organized into the same data package, and the current switch board number is added. The numbering step can facilitate the identification of the switch board source of the data packet later. After that, the switch board sends the sorted data packets and the received audio data packets from other switch boards to the next switch board of itself through the high-speed transceiver interface, and the next switch board also arranges the audio data packets that it has sorted by itself. And the received audio data packets from other switch boards are sent to the next switch board through the high-speed transceiver interface, and the switch boards are transmitted through independent high-speed transceiver interfaces, and so on, and the last switch board organizes itself The audio data packets received from other switch boards and the received audio data packets from other switch boards are sent to the first switch board through the high-speed transceiver interface, so the entire transmission process forms a ring topology, so that each switch board can obtain the The audio data of any agent box in any switch board in the whole system realizes that each agent box in the whole system can obtain the audio data of any other agent box, the number is not limited, and it does not follow the transmission of video data. The video and audio bundled transmission system has high flexibility and strong scalability. At the same time, because the audio data is extracted separately, and then the data is transmitted between the switch boards through the independent high-speed transceiver interface, instead of using the video blanking area transmission, the audio data bandwidth has also been greatly increased.

Further, the mth switch board obtains K groups of video data packets bound with audio data from K different agent boxes connected to the switch board, and the specific steps of extracting K groups of audio data independently include:

The mth switch board receives K groups of data packets, which are filled into data packets with a certain packet length after the audio data and video data are bundled by the K agent boxes connected to the switch board;

The mth switch board extracts the audio data in the K groups of data packets according to the lengths of different types of data, and adds the seat box number corresponding to each audio data.

In the present invention, the audio data and video data in the seat box are filled into data packets with a certain packet length, wherein the audio data length is different from the video data length. Therefore, the switch board can effectively distinguish the audio data and video data according to the lengths of different types of data. , so as to extract the audio data, and when extracting K groups of audio data from different K seat boxes of the same switch board, add the seat box number corresponding to the source of each group of audio data at the same time, which can be used to identify the specific audio data later. Box source for convenience.

Further, the mth switch board obtains K groups of video data packets with audio data bundled from K different agent boxes connected to the switch board, and the specific steps of separately extracting K groups of audio data from it include:

Determine whether different agent boxes connected to the same switch board need to transmit audio data to each other through this switch board. If so, the switch board extracts the audio data of different agent boxes connected to this switch board, and then performs the agent box according to the requirements. mutual transmission.

Further, the specific steps for the mth switch board to send the audio data packets organized by itself and the received audio data packets from other switch boards to the m+1th switch board through the high-speed transceiver interface include:

The mth switch board stores the audio data packets sorted by itself and the received audio data packets from other switch boards into the buffer to be sent;

When the high-speed transceiver interface is idle, the mth switch board sends the audio data packets in the buffer to be sent to the m+1th switch board through the high-speed transceiver interface.

In the present invention, the switch board first stores the data packet in the sending buffer, and then sends it, which can provide a buffer time before sending to the next switch board, because the data transmission between the switch boards in the system can pass the independent high-speed transceiver. When the data is transmitted, the transmission interface may be in a busy state, and the data packet is first stored in the send buffer area, and the transmission can be performed after the high-speed transceiver interface is idle, without causing data conflict.

Further, the m th switching board of the method sends the audio data packets organized by itself and the received audio data packets from other switching boards to the m+1 th switching board through the high-speed transceiver interface. Steps are also included before the step. : The mth switch board determines the source of the received audio data packet.

After the forwarding is completed, the audio data The packet is stored in the buffer to be sent; if not, the audio data packet is directly stored in the buffer to be sent;

In the present invention, after the switch board receives the audio data packet, it first parses the switch board number added when each switch board organizes its own audio data packet in the data packet. If the switch board number information shows that the audio data packet comes from this switch board, It means that the data packet has been transmitted to all switch boards and has gone through a round of transmission process of the entire system. Therefore, the data packet is discarded, and the audio data of this switch board is packaged and sent in combination with the above. The data packets are replaced with new audio data packets, so that the audio data can be continuously updated. If the switch board number information shows that the audio data packet comes from another switch board, the data packet will be buffered, and then according to the configuration of the main control system, it can be judged whether each agent box connected to the switch board needs the audio data packet. Data, if necessary, extract the corresponding audio data in the audio data packet according to the specific box number in the data packet, and forward it to the designated agent box. For example, if the agent box 11 connected to the switch board 1 needs to obtain the audio data of the agent box 22, when the switch board 1 receives the audio data packet from the switch board 2, it extracts the audio data from the agent box 22 and forwards it to the In the seat box 11. After the forwarding is completed, the data packet is stored in the buffer to be sent, and when the high-speed transceiver interface between the switch boards is idle, it is sent to the next switch board.

Another technical solution adopted by the present invention is that an audio ring transmission system in an optical fiber seat system includes N switch boards, the switch boards are connected to the seat box in the seat system, and are used for acquiring data in the seat box and performing For processing and transmission, the switch boards are all provided with independent high-speed transceiver interfaces, and the high-speed transceiver interfaces are used to send or receive data.
