The invention discloses a bridge health
monitoring system which comprises a sensing layer, a transmission layer, a
processing layer and an
application layer which are in communication connection in sequence. The sensing layer synchronously collects
structural mechanics, environmental influence and
traffic load data through multi-source heterogeneous sensing nodes, and the sensing nodes adopt a
solar energy and vibration energy double-source
energy supply and low-power-consumption mechanism; the transmission layer adopts a'
wireless private network + edge gateway '
mixed mode, and has data caching and
breakpoint resuming functions; the
processing layer analyzes data through a
deep learning fusion
algorithm based on an attention mechanism, and realizes dynamic early warning threshold adaptive adjustment in combination with a Bayesian reasoning model; and the
application layer provides a
visual interface, graded early warning and targeted maintenance decision suggestions. The
system achieves the precise monitoring of the
full life cycle of the bridge, improves the evaluation accuracy and
system stability, reduces the operation and maintenance cost, provides scientific support for the
safe operation and maintenance of the bridge, is suitable for the health monitoring scenes of various bridge types, and greatly improves the accuracy of the evaluation of the health state of the bridge.
