Summary:LXI(LAN Extensions for Instrument) distributed bus technology based on Ethernet had solved the problem of measurement at wide area. The test system consists of LXI bus acquisition instrument which can meet the shock wave signal test. In view of the characteristics of shock wave field such as it has many measurement points and the long acquisition time and the sampling rate. We designed the LXI bus distributed testing system. And the paper describes detailedly the composition of hardware and the framework of software. The paper does time and frequency analysis to the shock wave transient signal by wavelet transform and get the optimum decomposition level, and does the noise reduction and reconstruction process, The results show that compared with the traditional Fourier transform, this approach is easier to extract the characteristic parameters of shock wave.
