传统的声音信号提取技术都是用多个传感器节点独立实现,本文提出了一种基于无线传感器网络实现声音信号提取和传输的新思路,实现了由独立到系统的转化。本系统将声音传感器与无线传感网络节点相结合,实现声音信号的提取;在新型的无线传感网络操作系统SOS上加载了相关的路由协议模块和数据融合模块,实现声音数据在各个节点之间的多跳传递;利用无线传感器网络动态监控声音信号的变化,设计一套界面管理软件,并给出动态效果图,从而更直观地看到声音信号的变化。
The traditional sound signal extraction technology is implemented by multiple sensor nodes independently. In this paper, a new idea based on wireless sensor network to extract and transmit sound signals is proposed, and the conversion from independent system to system is realized. The system combines the sound sensor with the node of the wireless sensor network to realize the extraction of the sound signal. In the new wireless sensor network operating system SOS, the relevant routing protocol module and data fusion module are loaded to realize the sound data at each node Multi-hop transmission between wireless sensor networks; dynamically monitoring the change of sound signals by using a wireless sensor network; designing a set of interface management software and giving a dynamic renderings so as to more directly see the change of sound signals.
