摘　　要：随着国民经济的发展,音频处理、传输、控制技术发展迅猛并日趋成熟,音频扩声系统在党政军企等各类会议、远程视频会议、指挥中心等场所成为标配,发挥了越来越重要的作用。在科技带来无限便利的同时,人们也对系统的可靠性提出了更高的要求,一套稳定、智能、系统自愈的音频扩声系统成为工程设计的目标。本文主要介绍一种采用全链路自动备份设计、智能切换路由的音频扩声系统架构,并对关键技术等进行分析。With the development of the national economy, audio processing, transmission and control technologies are developing rapidly and becoming more mature. Audio amplifying system has become a standard configuration in various conferences, remote video conferences, command centers and other places of the party, government, military and enterprises, and has played an increasingly important role. While science and technology bring infinite convenience, people also put forward higher requirements for the reliability of the system. A stable, intelligent and self-healing audio sound reinforcement system has become the goal of engineering design. This paper mainly introduces an audio sound reinforcement system architecture which adopts full link redundancy automatic backup design and intelligent switching routing, and analyzes the key technologies.
