Centreless voice conference system

Technical Field

The invention relates to the technical field of voice conference systems, in particular to a centerless voice conference system.

Background

The traditional voice conference system generally has a voice server as a central node, other nodes are accessed to the server through a voice terminal, and the server distributes voice data to each client after performing audio mixing processing. The biggest problem of such a communication network architecture is that after the central server is destroyed, the whole voice system will be paralyzed and unable to operate. Therefore, as a military voice communication system, it is necessary to have a centerless survivable network architecture and a bidirectional voice real-time communication function. To this end, we propose a centerless voice conference system.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a centerless voice conference system comprises a sending module 1 and a receiving module 4, wherein the sending module 1 comprises a VAD detection unit 11, the VAD detection unit 11 is electrically connected with a voice acquisition unit 12, the voice acquisition unit 12 is electrically connected with a voice coding unit 13, the voice coding unit 13 is electrically connected with a data sending unit 14, the receiving module 4 comprises a data receiving unit 41, the data receiving unit 41 is electrically connected with a voice decoding unit 42, the voice decoding unit 42 is electrically connected with a mixed voice processing unit 43, the mixed voice processing unit 43 is electrically connected with a voice broadcasting unit 44, the sending module 1 detects voice through the VAD detection unit 11 and activates the voice acquisition unit 12 to collect voice, and sends the voice to a designated port of a broadcast address in a broadcast packet mode after the voice is coded through the voice coding unit 13, the transmitting end can set different coding modes (such as G.711; G.723, etc.). The receiving module 4 monitors the broadcast packets sent by different nodes on the network at the designated port, analyzes the data packet header, and discards the non-voice packet and the voice packet sent by the node. And establishing an independent decoding channel for each node, and decoding according to the corresponding coding mode. Then, the multi-channel decoded voice data is subjected to sound mixing processing, and finally, the voice data is pushed into the loudspeakers 6 to be played, each microphone 2 can control each loudspeaker 6, and the sound of each microphone 2 can be transmitted out from each loudspeaker 6.
