AI Technical Summary

Problems solved by technology

The wireless speaker can receive the audio data of multiple microphones, and can also receive the audio data from the PC. The design scheme, the speaker is fixed in receiving mode, multi-channel receiving is turned on, and the rest of the nodes are fixed in sending mode, so it is difficult for the PC to receive the button information of the microphone (because the PC needs to continuously scan the microphone)

Embodiment

[0024] figure 1 It is a structural diagram of a specific implementation manner of the multi-node voice data transmission method of the present invention.

[0025] figure 2 It is a flow chart of the multi-node voice data transmission method of the present invention.

[0026] In this example, if figure 1 As shown, take the data transmission model of multimedia teaching as an example, including: wireless microphones (there may be multiple), wireless speakers, and PCs. In this model, there is actually no distinction between primary and secondary, but here we introduce The concept of the master control node and the slave node stipulates that the wireless speaker is the master control node, and the two microphones and the PC are the slave nodes. In practical applications, the master control node and the slave node should be drawn up according to the actual situation.

[0027] A kind of transmission method of multi-node voice data of the present invention, such as figure 2 show...

Abstract

The invention discloses a multi-node voice data transmission method. Through the method that broadcast frames are sent by a master control node, the slave node adopts whole network unified synchronization to transfer data in different time slots, in essence, time division multiplexing is performed on channels, so the multi-node voice data transmission does not depends on the increase of hardware too much, and the multi-node voice data transmission is completely completed through software compiling protocols, so that the cost can be reduced, and at the same time, the system flexibility and development can be improved, so the system can adopt to the current wireless technology development trend.

Description

technical field [0001] The invention belongs to the technical field of wireless transmission, and more specifically relates to a transmission method of multi-node voice data. Background technique [0002] With the continuous development of wireless technology, more and more occasions need to use wireless methods to transmit data. Because it is easy to install, flexible, and avoids the limitations of wired connections, it is gradually used in various occasions, but With various occasions, such as: teaching, conferences, stages, and various entertainment venues, the requirements for equipment continue to increase, and wireless transmission is no longer limited to the simple one-send-one-receive mode, but towards complex data sent and received by multiple nodes Transmission development. For example: In major entertainment venues, stages, and KTV, most wireless microphones are used, and there are usually multiple wireless microphones, but there is only one wireless speaker, whi...
