Shanxi Large Bridge Cluster Structural Health Monitoring

A multi-bridge structural health monitoring system for a provincial long-span bridge cluster, integrating 800+ sensor-level deployment, distributed acquisition, and centralized DL-SHM monitoring.

Project Type

Civil Infrastructure Structural Monitoring

System Scale

8 long-span bridges with 861 total sensors, including distributed acquisition, installation, commissioning, and online trial operation

Data Output

multi-bridge vibration, cable force, strain, displacement, tilt, temperature, environmental status, and alarm records

Engineering Value

How the system supported engineering decisions

The case establishes civil infrastructure as a core vertical for large bridge cluster SHM.

DL-DAQ distributed acquisition and DL-SEN field sensors were mapped into one DL-SHM monitoring center.

The 861-sensor deployment demonstrates 800+ sensor system delivery, commissioning, and online operation capability.

Monitoring Content

Monitoring scope and field constraints addressed by the deployment

Eight bridges required consistent sensor coding, acquisition hierarchy, commissioning workflow, and monitoring outputs across separate structures.

The 800+ sensor scale required distributed acquisition architecture instead of a single cabinet-only layout.

Bridge owners needed long-term structural safety visibility for cable force, vibration, strain, and operating-state review from one monitoring center.

System Configuration

Field Devices

DL-SEN acceleration, strain, displacement, tilt, temperature, and cable-force sensors installed across bridge spans, towers, cables, decks, and support zones

Communication Layer

Distributed DL-DAQ acquisition stations aggregate field signals bridge by bridge before transferring data to the monitoring center
