Structure Health Monitoring

The low to mid frequency vibration, especially < 1 Hz, is considered critical to infrastructure health as excessive vibration in this range can lead to structural integrity issues on rail and high-speed train infrastructures, bridges and tunnels, towers, wind turbines, and buildings. Acquiring and analysing ultra wide broadband vibration data is a powerful tool for digitised asset condition monitoring, risk management and disaster prevention and early warning.

Frequency Range Estimated Dynamic Displacement (FREDD)

Our system can provide accurate displacement readings in frequency range as low as 0.3Hz and up to 1600Hz, perfect for monitoring rail bridge and foundation movements. Our vibration-based monitoring solution does not require reference points, and costs only a fraction of that of other displacement measurement method such as LiDAR, and fiber optics. We have the first commercially available vibration sensing technology to compare displacement readings against a dial indicator with 0.001 inch (0.00254cm) accuracy.

Crack Mechanism Analysis

Vibration data can also be used to analyse crack mechanisms on bridges, foundations or beams.

Structural Diagnostics

Diagnose whether issues are caused by wind or train load.

Infrastructure Health Examination

We can monitor the natural frequency shift in ageing infrastructures or structure conditions after incidents.

How it works
  1. Network Design: During the free consultation with our project specialist, we will help the client determine the number of stations needed, best installation locations, and monitoring durations based on the client’s monitoring goals. We can customize device network settings, power supply, attachment method, and firmware depending on access to power, wireless network options, connectivity protocols etc.

  2. Field installation: Each station can be setup within hours. Each System includes three geophones for triaxial measurement, fixed in place with eco friendly and non-intrusive methods such using sandbags, strap or magnet, a locked digital box that contains circus boards, SD card to store data, LTE data transmission module, battery and a 100W solar panel.

  3. Access of data: Time synced velocity, acceleration, or displacement data is transmitted through wireless network to the client’s own or Symroc’s server or any cloud service of choice. Data can be viewed in real time or downloaded using Symroc’s web-based interface or software.

  4. Report: We can also deliver the data and analytic results as periodical reports delivered to the clients electronically via email or cloud services.
