Abstract：By taking CompactRIO as hardware platform, and using LabVIEW FPGA technique, the paper bring about the bottom data acquisition function of 48 channel strong motion data acquisition. The paper elaborates the key points of design in detail, and technically realizes the function of clock synchronization, data acquisition, calibration signal output, range set, state show, external triggering signal access, etc. The results show that the recorderˊs main technical indicators, for example, noise, dynamic range, frequency response, etc, meet the domestic requirements of seismic industry standard DB/T 10-2001 and linearity error meets the DB/T 22-2007. The stage result realized can provide important reference for people who will develop strong motion data acquisition by use of NI products.
