通过对MATLAB/xPC Target经TCP/IP网络连接,与PCL-1800数据采集卡构成的半实物仿真系统的介绍和分析,采用MATLAB小波工具箱,对光纤电压传感器经信号调理电路采集的信号进行仿真,结果表明小波分析能有效的去除采集信号的谐波和噪声干扰。
Through the introduction and analysis of MATLAB / xPC Target via TCP / IP network connection and the hardware-in-the-loop simulation system with PCL-1800 data acquisition card, the signal collected by signal conditioning circuit of fiber voltage sensor is simulated by MATLAB wavelet toolbox The results show that the wavelet analysis can effectively remove the harmonics and noise of the collected signals.
