Audio transmission and control system equipment based on network communication technology

Abstract

The invention relates to audio transmission and control system equipment based on a network communication technology, and the equipment comprises a main control machine room, branch control machine rooms, an LAN local area network, and a terminal broadcast, wherein a network audio server, a network audio coding expander, a network microphone paging working station, and a network fire alarm matrixare arranged inside the main control machine room. All the devices are connected with a switch through network cables; the network audio coding expander is used for coding the received audio signal into a digital signal and transmitting the digital signal to the switch by adopting a TCP / IP protocol; IP broadcast management software is installed on the network broadcast sub-control management computer or the user computer, and a function bar on the left side and a function information display bar on the right side are arranged in a partition management mode. According to the invention, the problem of limitation of a line or a transmission distance of an analog broadcasting system is effectively solved, a network mode is adopted, and the transmission distance is long; each terminal has an independent IP address, and one terminal can be randomly controlled to play different programs.

Description

technical field [0001] The invention relates to the technical field of audio transmission systems, in particular to an audio transmission and control system equipment based on network communication technology. Background technique [0002] The analog broadcasting system can only use analog signals output by microphones, CD players and other equipment, and cannot be applied to audio sources stored in digital formats on network servers and various carriers. Analog broadcasting systems are easily limited by power and lines, and the transmission distance and the number of sounding units are difficult to expand. The analog broadcasting system is a set of hardware equipment. Its application functions and management functions are fixed and limited. It cannot achieve arbitrary point-to-point, unlimited partitions, multi-task presets, etc., and is not flexible enough. Therefore, there is an urgent need to design an audio transmission and control system equipment based on network com...

[0002] The analog broadcasting system can only use analog signals output by microphones, CD players and other equipment, and cannot be applied to audio sources stored in digital formats on network servers and various carriers

Analog broadcasting systems are easily limited by power and lines, and the transmission distance and the number of sound units are difficult to expand

The analog broadcasting system is a set of hardware equipment. Its application functions and management functions are fixed and limited. It cannot achieve arbitrary point-to-point, unlimited partitions, multi-task presets, etc., which is not flexible enough.

Therefore, there is an urgent need to design an audio transmission and control system equipment based on network communication technology to solve the problems of short transmission distance, inability to point-to-point, arbitrary partition, and difficult expansion of traditional broadcasting systems
