|
摘要
为解决非接触电导检测系统易受噪声干扰的问题,介绍了一种基于FPGA的FIR数字滤波器解决方案.应用Matlab中的Simulink对非接触电导检测模型建模并产生信号,通过DSP Builder搭建的FIR数字滤波器对信号的高频噪声进行滤波处理,最后用FPGA仿真相应功能.仿真结果表明:FIR数字滤波器可以较好的滤除电导检测中的高频噪声,系统处理速度快,运行稳定可靠,适合于非接触电导检测.
To solve the noise problem of contactless conductivity detection system,we introduced a solution of FIR digital filter based on FPGA. Firstly,Simulink of Matlab is used to establish a model for the contactless conductivity detection and producing the signal. Secondly,the FIR digital filter built by DSP Builder filters out the high frequency noise of the signal. Finally,the corresponding function is simulated by using FPGA.The experimental results show that the FIR digital filter can greatly filter out the high frequency noise of the contactless conductivity detection. The system has the advantages of fast processing speed,high stability and reliability,which is suitable for the contactless conductivity detection.
