    • Abstract
  • The paper introduced design of a noise source analyzer for industrial compressor based on frequency spectrum and wavelet transform.The analyzer takes LabVIEW as software development platform,adopts methods of frequency spectrum analysis and continuous wavelet transform to analyze position and recognition of noise source of industrial compressor,and has functions of collection and processing of noise signals,recognition methods of frequency spectrum analysis and continuous wavelet transform and so on.The test result showed that the two recognition methods can distinguish each noise source of industrial compressor and everyone’s contribution in noise power of compressor,so it is easy to locate range of frequency bands distribution of main noise source quickly and visually,so as to monitor running status of industrial compressor.
