Existing civil engineering structure health monitoring system usually use random demodulation（RD）mode for information sampling

while with the frequency band of sampling signal become more wider and the amount of data become more larger

the problem of poor expandability

low transmission capacity and high cost of inherent monitoring system become more obvious than any time.Aiming at above shortcomings

an improved analog to information converter（AIC） combining with compressed sensing（CS） theory is designed based on uniform sampling method. And corresponding system structure

software and hardware implementation method is designed for monitoring of practical analog signal. The result of experiments show that the system accomplishs acquisition

compression and reconstruction of analog input signal with fewer observation values and it reduces energy consumption and hardware cost of sensor network greatly.
