代码说明:

资源描述有源码有数据有论证,研究成果在太阳能学报(EI)上发表。针对风力发电机组传动系统故障时特征量提取困难的问题,提出改进的小波包结合包络谱的故障诊断新方法。深入研究小波包频带错乱的问题,对小波包实施改进,消除频带错乱的缺陷。首次将改进的小波包与包络谱结合起来,通过对风机传动系统试验台的齿轮、轴承故障实际数据的深入分析,准确提取出特征量,实现故障的诊断和定位,证实该文提出的方法的准确性和有效性,为风电机组传动系统的故障诊断提供新思路。

  • gnss-sdr-master
    In order to start using GNSS-SDR, you may want to populate ```gnss-sdr/data``` folder (or anywhere else on your system) with raw data files. By raw data we mean the output of a Radio Frequency front-end s Analog-to-Digital converter. GNSS-SDR needs signal samples already in baseband or in passband, at a suitable intemediate frequency (on the order of MHz). Prepare your configuration file, and then you are ready for running ```gnss-sdr config_file=your_configuration.conf```, and seeing how the file is processed.
