摘　　要：介绍了以美国德州仪器公司(TI)C2000系列DSP—TMSF320F28335(简称F28335)为核心的风力发电机远程检测分析系统。该系统充分利用了F28335丰富的外设模块和专用以太网控制芯片RTL8019AS实现了包括模拟信号、数字信号、频率信号的数据采集,并且具有串口、CAN总线、以太网3种通信功能。该系统对采集的信号进行FIR数字滤波和快速傅里叶变换(FFT),得出信号的时域和频域数据,利用小波分析、Hilbert-Huang变换等算法对时、频域数据进行特征提取和分析,得出风力发电机的运行状态和故障信息,实现系统的在线监控与故障识别。Introduce the wind turbine remote detection and analysis system on the core of Texas Instruments the United States （TI） C2000 series DSP-TMSF320F28335 （referred F28335）.The system takes full advantage of F28335-rich peripheral modules and uses the dedicated Ethernet controller chip RTL8019AS achieve data acquisition including analog, digital signal, the frequency sig- nal, and has three kinds of communication of serial port, CAN bus and Etheruet. The system transforms the capture signal through FIR digital filter and FFT, obtain the time domain and frequency domain data, using wavelet analysis, Hilbert-Huang transform al- gorithm extracts and analysis the feature of frequency and time domain data, obtain the operating status and fault information of wind turbine to achieve online monitoring system and fault identification.
