Real-time Analysis System Based on ARM and DSP for Audio-frequency Stress Wave

摘要：

In this paper, by introducing audio-frequency stress wave reflection detection principle, an audio-frequency stress wave analysis system is presented and designed. The design based on a high performance FPGA of EPM7128, DSP of TMSVC5509 and an ARM chip of S3C2440 are introduced. FPGA is used as the core of data acquisition, DSP is used as the core of data processing, accompanied with S3C2440 chip as the core of data display and system control,and embedded operation system Linux is adopted as software of system. And the experiment results show that the method based on FFT, Wavelet transform, and Hilbert transform achieved good performance for audio-frequency stress wave reflection detection.
