基于无线传感网ZigBee扩音机设计

Design of Megaphone Based on Wireless Sensor Network ZigBee

针对传统扩音机在特定环境应用中,存在扩音距离短、不能使用点对点的服务,提出应用无线传感网络ZigBee技术,构建扩音机系统设计方案。给出了扩音机的体系结构、硬件实现、软件实现框图,并分析了各模块功能及信号处理流程,便于系统功能扩充。

Design of the megaphone system that use wireless sensor networks ZigBee technology is proposed,in order to solve the traditional megaphone＇s problems of short transmission distance and lacking point to point service in a specific application environment.The architecture of megaphone as well as hardware,software block diagram is given in this paper.The function of each module and signal processing are analyzed,which is easy to expand system functionality.
