摘　　要：基于网状路由的音频传输调度系统可实现根据优先权重动态调度调音台输出端至发射机输入端的音频信号路由,由此提高广播播出链路的可靠性。本文以南京广电集团广播音频传输调度系统建设实践为例,详细介绍了节点化设计、系统网状结构建设、路由算法流程和路由调度软件,最后对系统的优势进行了分析与总结。Based on a meshed routing audio transmission scheduling system,it enables dynamic scheduling of audio signal routes from the mixing console output to the transmitter input based on priority weights,thereby improving the reliability of the broadcasting transmission chain.Taking the construction practice of the audio transmission scheduling system at Nanjing Radio and Television Group as an example,this paper provides a detailed introduction to nodal design,system mesh structure construction,routing algorithm process,and routing scheduling software.Finally,an analysis and summary of the system's advantages are presented.
