摘　　要：针对牢房视频监控的实际需求,提出了一种多路音频联网器的总体设计方案,使进入联网器的每一路视频信号都能够在指定的一路或多路监视器上输出,同时完成音频信号的同步切换,从而实现了多系统间音视频信号的传输控制,使构建分布式、智能化的监控系统成为可能。详细介绍了联网器的硬件设计原理和软件流程图。The architecture of an audio multiplexer is presented, which is used in prison video surveillance system. The hardware design and software framework of audio multiplexer are discussed in detail. Each video signal coming into audio multiplexer is switched to the designated output, with audio signal switched synchronously. The transmission control of audio-visual signals among systems makes it possible to build a distributed and smart video surveillance system.
