内容提要

广播作为弱电系统的一个组成部分，紧密联系着人们的现代生活，既能播放音乐，又能作业务宣传和寻呼广播，还能作为火灾事故的紧急广播，是一种通用性极强的广播系统。本设计采用音泰尔（YTAER）背景音乐与应急广播系统，包括公共广播系统以及紧急情况下疏散人群的消防广播报警系统。本系统采用总线制连接，不仅节省了工程成本而且使得日常的设备检修变得简单快捷，真正实现了一个系统实现两种功能的兼容效果。音泰尔（YTAER）系列背景音乐与应急广播系统具有高可靠性、智能化、配置灵活等特点，并可与消防系统充分融合，是一款中档的通信广播消防系统。系统中音源通过前置放大器、广播录放盘、功率放大器等实现音源信号的放大、转换以及声音的美化等过程。然后调整好的音源到各区域控制模块，这些模块可以使各区扬声器播放背景音乐也可以将紧急信号播放在现场扬声器。本系统的各个构成单元以及各种安装件均采用了模块化结构，以便根据业主要求灵活地进行组合，扩展，也方便业主以后对系统进行升级。企业：深圳市亚米欧科技姓名：康振兴联系方式：

Abstract

Broadcast as a part of weak systems, it contacts with people of modern life close, its both can play music, and can for business publicity and page broadcast, also can as fire accident of emergency broadcast. The design using the YTAER series of backgroundMusic and emergency broadcast systems, including public broadcasting systems, and emergency evacuation under fire radio and alarm system. This system bus connection not only saving engineering cost and can make it easy and fast to routine equipment maintenance, it realizes the effect of a system to achieve compatibility of the two functions.

YTAER series background music and emergency radio system with high reliability, intelligent, flexible configuration features and fully mix it with fire-fighting system, is a medium of communication radio and fire control system. The sound source of the system via the preamplifier, power amplifier, radio and recording disc to realize audio signal amplification, conversionand the beautification process of the sound.Then the audio source be adjusted to the regional control module, these modules can make the loudspeaker to broadcast background music and can also be played at the site of the emergency signal loudspeaker. This system's units and various fittings are made of modular structures, according to owners' requests to combine, extend, facilitate future upgrades to the system flexibly.

Keywords:information dissemination ; background music; fire radio
