Pipeline Leak Signal Acquisition And Processing Technology Research

This thesis's intention is to develop a cheap pipeline leaking detecting and locating system. In this paper, Rayleigh Wave is studied. Based on energy statistic arithmetic, the author discussed how to design a signal acquisition and signal processing system. In our field, this system works well and locates position of leakage along the pipeline. This system holds these character: small, easy to use.This thesis also discussed how to design a filter based on FPGA.DSP is the trend of signal processing application. So the author also explored how to design a signal acquisition system based on DSP.
