矿用数字广播系统设计

摘要

针对煤矿井下广播系统模拟音频广播方式存在灵活性差、语音通信范围小等问题,提出了一种新型的矿用数字广播系统设计方案,介绍了系统的总体结构、音频终端及网关程序的设计.该系统将音频终端接入工业以太网,实现了分组和定点广播,解决了井下的单播、组播问题.%For problems that underground broadcasting system with analog audio broadcasting mode has poor flexibility and small voice communication range, the paper proposed design scheme of a new kind of mine-used digital broadcasting system, introduced designs of overall structure of the system, audio terminal and gateway program. The system accesses the audio terminal in industrial Ethernet, realizes packet and designated broadcasting, which solves problems of underground unicast and multicast.
