摘要:

摘要:针对电容层析成像ECT(electrical capacitance tomography)数据采集系统中的高频噪声干扰问题,在对ECT系统数据采集与控制原理分析的基础上,基于数字滤波原理和FPGA技术,设计了一个基于数字滤波与FPGA技术相结合的改进分布式算法FIR低通数字滤波器。该滤波器的采样频率为1.5 MHz、通带截止频率为20 MHz,选则窗函数设计方法,利用Matlab中的FDATool工具箱对滤波器系数进行提取与量化,最后利用Quarters对实例进行仿真验证,实验结果表明,FIR数字滤波器能够实现数据采集系统中高频信号的滤波功能,与传统DA算法的滤波器相比,具有占用资源消耗小及采集速度快等特点。
Abstract:
Abstract:Aiming at the problem of high frequency noise interference in the ECT data acquisition system,on the basis of analysis of the ECT system data acquisition and control principles,we designed an improved distributed algorithm FIR low-pass digital filter combined with FPGA technology and digital filtering principle. The sampling frequency of the filter is 1 .5 MHz,the pass band cutoff frequency is 20MHz,and the design method is window function. We used the FDATooI toolbox in Matlab to extract and quantify the filter coefficients and the Quarters to simulate the simulation. Experimental results showed that the FIR digital filter can achieve the filtering function of the high frequency signal in the data acquisition system. Compared with the traditional DA algorithm,it has the advantages of small resource consumption and high acquisition speed and some other characteristics.
