摘要

介绍了一种具有到达时间差（TDOA）定位机制的基于数字信号处理器（DSP）的无线传感器网络节点。它包括TMS320F2812DSP

512 kB的SRAM

2.4 GHz波段的无线收发模块、音频信号收发模块及电源管理模块等。节点通过测量RF同步信号与音频信号的TDOA来测量节点间的间隔距离

并采用互相关时延估计算法来实现节点定位。实验数据表明:该节点最远测距距离超过25m

角度误差小于3.7%。

Abstract

A wireless sensor network node with acoustic localization based on DSP is introduced.It includes a TMS320F2812 DSP

a 512 kB SRAM

a 2.4 GHz RF transceiver

a acoustic signal transceiver unit and a power management unit.The node’s distance can be measured by time difference of arrival（TDOA）between radio frequency（RF）and acoustic signals.The node’location can be realized by adopting cross correlation time delay estimating algorithm.Test results show that the node can measure the distance longer than 25 m with error less than 3.7 %.
