摘要：

Structural monitoring is often considered as computer memory consuming for storing data over long term periods. An alternative to classical data acquisition systems lies in the use of smart acquisition systems. Data is locally processed and sent to a central controller system. The paper explains the advantages of such an acquisition system. It also describes the REVE system designed in LCPC and intended to be extensively used in France on bridges for assessing load effects in a near future. Results on a reference bridge chosen for the system development and calibration - the Bruneseau bridge in Paris - are given. The system is designed to provide of data histograms, level crossings histograms (for extreme load effects extrapolation) and rainflow histograms (for fatigue damage assessment).
