Infrastructure and Construction

These days, the increasing amount of infrastructure such as bridges and roads, buildings, and houses has passed their estimated service life. In step with this reality, maintenance checkups of existing infrastructure have become an important social concern. In addition, real time measurements of damage to infrastructure and structures is not popular as a way of preparing for the occurrence of earthquakes or other types of disasters.
TAIYO YUDEN's small, easy-to-use, high-precision optical displacement sensors, which can be installed in existing infrastructure or structures, can detect, for example, vibrations and displacement in real time, enabling various measurements such as structural or passing vehicle monitoring, and predicting future changes that may indicate danger or affect people's lives.

Example applications in infrastructure and structures

Structural monitoring

Passing vehicle detection

Vibration detection

Danger prediction

Prediction of the longevity of infrastructure and structures

Example applications in infrastructure and structures

  • Continuous measurement and monitoring of construction
  • Measurement of traffic volume and load
  • Evaluating the number of passing overloaded vehicles that can shorten the life of bridges to properly assess the timing for maintenance
  • With "autonomous power supply + measurement + transmission" based on a solar battery and storage device, the device can be installed even in places where no power supply is available.
  • Wiring and other construction costs can be reduced by making communications wireless.
  • Multiple communication methods can also be combined in accordance with requirements such as data volume, frequency, and installation environment.
