数字网络广播与消防应急广播的对接设计

Docking Design between Digital Network Broadcast and Fire-fighting Emergency Broadcast

针对传统广播系统传输距离短、音质不佳、系统扩展性差等问题,结合工程案例分析,给出一种优化的技术方案;该方案中消防应急广播系统和数字网络广播系统分界清晰,传输干线独立,系统构架充分考虑了IP广播系统的特点,易于实现且成本相对较低,并符合消防验收要求。

Combined with some project cases, an optimized technical proposal is provided for the problems of traditional broadcasting systems, such as short transmission distance and bad tone quality and system expansibility, in which the dividing line between the fire-fighting emergency broadcasting system and the digital network broadcasting system is clear, the trunk transmission line is independent, the characteristics of IP broadcasting system is fully considered for the systematic framework. Moreover, the proposal is realized easily, the cost is relatively low, and it meets the acceptance requirements of fire fighting.
