摘要

针对结构健康无线传感器网络监测系统中

需要对节点数据进行预处理问题

采用FPGA(field-programmable gate array)为硬件平台

设计了FIR(finite impulse response)数字滤波器

对节点的数据进行数字滤波处理.设计中利用MATLAB/Simulink、DSP Builder软件对数字滤波器进行建模、滤波系数计算、系统模型仿真和生成相应的VHDL工程文件;利用Quartus-II软件对工程文件进行综合、编译和调试

并且生成相应的底层原理图模块.通过对1 kHz和4 kHz的两个正弦波混合信号进行仿真滤波表明

4 kHz的高频干扰信号被有效地滤除

实现了FIR滤波器的性能.将生成的VHDL代码下载到FPGA中

实现了基于FPGA的FIR滤波器设计.

Abstract

In wireless sensor networks for structural health monitoring system

we need to preprocess the data of node

so we designed a FIR(Finite Impulse Response) digital filter to node data processing digital filtering.In this design

we use the FPGA(Field-Programmable Gate Array) hardware platform.This design uses MATLAB/Simulink

DSP Builder software to model the digital filter

calculate filter coefficients

simulate system model and generate the corresponding VHDL project files.Quartus-II software is use...
