摘　　要：为真正体现广播作为处理突发事件的工具的功能,设计研制了一种基于全球移动通信系统(Global System for Mobile communications,GSM)网络的音频功率播放器。在现有广播技术的基础上,结合GSM无线通信技术,使用单片机系统作为中心处理器,解决对各个终端的同时访问和有效控制,实现了一对多个终端站点同时广播。能够实现远程操控,且设置了安全权限,实现无人值守的全自动智能控制多终端音频广播系统。特别适用于远程多站点同时广播。An audio power player based on GSM（global system for mobile communications） network is designed to truly re- flect the broadcast as emergency tool. The broadcast system based on the existing broadcasting technology, combined with the GSM wireless communication technology, the use of single -chip microcomputer as the central processor, to solve the terminal access and effective control, to achieve a multi terminal sites simultaneously broadcast. It can realize remote con- trol, and the set security permissions, automatic intelligent control terminal audio broadcasting system for unattend- ed. Especially suitable for remote multi site simulcast.
