Bridge Monitoring System
Critical infrastructure reliably monitored:
autonomous monitoring of railway bridges
Bridges are critical assets, and their continuous monitoring is essential for ensuring the safety, availability, and long-term performance of rail infrastructure. The autonomous bridge Monitoring System provides continuous condition monitoring of railway bridges during regular operations, delivering precise data on structural response under traffic loads.
The system enables the early detection of critical structural changes before they develop into safety-related issues, service disruptions, or costly damage. The result is an objective, data-driven basis for maintenance planning, structural integrity assessment, and service life prediction.
In addition to structural responses, the system records operational traffic parameters, identifies passing trains, and measures axle loads. This provides comprehensive information on both traffic and the resulting structural stress and structural response.
The Bridge Monitoring System autonomously records and analyzes all key structural parameters, including strain, stress, deflection, displacement, acceleration, and vibration, enabling continuous assessment of bridge condition and performance under real operating conditions.
Bridge Monitoring System Application Areas
- Construction monitoring
- Structural health assessment, ensuring load bearing capacity and serviceability
- Calibration of calculation models
- Investigation of higher load capacity
- Damage detection via crack width measurements
- Damage detection via changes in natural frequencies
Bridge Monitoring System Analyses
- Maximum strains/stresses or deflections
- Fatigue analyses (e.g. based on rainflow counting)
- Acoustic indicators for material changes
- Analyses in the frequency domain: natural frequency analysis, modal analysis, wavelet analysis, frequency filter
- Further analyses can be added modularly
- All measurement and analysis results are available at any time in the internal network or on the Internet/IoT
