Example 2:
as shown in fig. 2, it is assumed that a certain intercom system includes A, B, C, D, E and F six intercom terminals. Wherein A is the talkback terminal initiating the voice communication, B, C, D are all in the communication range of A and the direction is different, E is located outside the communication range of A and in the communication range of C, D, and F is located in the communication range of E. A, C, D, E is identical to the block code of F and is different from the block code of B.
When voice communication is started to A, voice is collected and converted into a0 voice packets and a1 voice packets in sequence according to time sequence, and the voice packets are stored in sequence and sent out in sequence. B. C and D both receive the voice packet sent out by A, B compares after receiving the voice packet, the block code marked in the block code information in the voice packet is different from the block code of B, therefore B does not process the voice packet; the block codes of C and D are the same as the block codes marked in the block code information in the voice packet, the A0 is processed and the sequence number of the A0 is saved by the C and D, the A0 is synthesized into voice by the C and D, and the A0 is forwarded outwards.

After the C and the D forward a0, A and E are both in the coverage range of the C and the D; at this time, A is that the voice initiating terminal does not receive any data; the a0 sent by the C arrives at the E before the a0 forwarded by the D, no voice packet is stored in the E, the E processes the a0 forwarded by the C and forwards the voice packet outwards, and when the a0 forwarded by the D arrives at the E, the E stores the sequence number of the a0 forwarded by the C, and the sequence numbers of the two are the same, so that the arriving a0 is not processed. The same points between the case of E receiving a1 and the case of E receiving a0 are not described in detail, but the stored sequence number of a0 is cleared and the sequence number of a1 is stored, while the sequence number of a0 stored in E is compared with the sequence number of a1 received.
E after sending out a0, C, D, F all receive a 0; at this point the sequence number of a0 saved in C, D is the same as the sequence number of received a0, so C, D no longer saves received a 0; f, normally receiving a0, storing, analyzing and sending again; f only has E in the communication range, and the E stores the ordinal number of a0, so the E does not store a0 sent by F.
At present, most of remote communication among a plurality of talkback terminals needs relay equipment, and the erection cost is high and the applicability is low. Some communication systems do not use relay equipment, but need to be networked through a routing table before use, and the networking needs a certain time, and the number of the talkback terminals in the communication system is limited due to the storage space of the routing table.

One of the talkback terminal side collects voice and converts the voice into a plurality of voice packets and sends the voice packets outwards in sequence, and the talkback terminal located in the communication range of the talkback terminal synthesizes the voice packets into voice and forwards the voice packets outwards again after receiving the voice data packets. The voice packet is sequentially spread outwards by taking the talkback terminal initiating the voice communication as a center until all talkback terminals, and the talkback terminal positioned in the middle level not only receives the voice packet and synthesizes the voice, but also plays a role of relaying. The intercom system does not need relay equipment and networking, so that theoretically, an infinite number of intercom terminals can carry out cascade communication.
The voice packets transmitted by the voice communication of the invention comprise sequence number information, and the sequence number information is used for marking the generation sequence of a plurality of voice packets. The transmission direction of the voice packet is ensured through the sequence number information during the transmission of the voice packet, the return and repeated receiving of the voice packet are avoided, the load of the whole talkback system is reduced, and the communication efficiency is improved.
The voice packet transmitted by the voice communication of the invention comprises the block code information, and the block code information is used for recording the block code of the talkback terminal which generates the voice packet. The group code is generated by a group module in the talkback terminal, and the talkback terminals with the same group code can communicate with each other to ensure the privacy of voice communication.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
