Fiber Bragg Grating (FBG) technology
FBG technology brings many advantages over the conventional sensing methods, such as immunity to EMI/RFI, high precision, durability, quasi-distribution and absolute measurement, compact size, reduced cable requirement, etc.
Early warning in case of events
The monitoring system is equipped with direct alarm relays for immediate notifications to be sent via email or other communication interfaces in case of sizeable and unusual events.
Multifunctional measuring platform
Several sensors with different functions can be connected in series on a single fiber without signals being confused and with the necessary cable length being considerably smaller.
Service and maintenance planning
We will help you optimize your service and maintenance planning based on your specific needs to ensure efficient operation.
Prevention of catastrophic failures
Thanks to the structural health monitoring of tunnels, you’ll be able to take appropriate action in advance and thus minimize potential damages and losses.
Predicting structural deformation trend
By analyzing the measured data, structural deformation trends can be predicted and the level of the tunnel structure safety can be evaluated to provide key technical parameters and timely warning.
Use of existing fiber optic network
Installation of an expensive sensor infrastructure or availability of electrical power is not necessary, which is very economical even for large areas of monitored objects.
Reporting and data analysis
Our solution for monitoring tunnels provides all necessary reporting and data analysis features. The available level of service is in accordance with SLA.
Customized solutions and adjustments
The solution can be modified to meet your project’s needs, such as the desired functionality, interoperability, and others.
System management and data acquisition via the Internet
You will be able to manage the solution via a user-friendly web interface, which also provides all necessary information about the structure and reporting and data analysis features in accordance with your SLA.
Measuring over long distances
The distance between the unit and sensors can be up to several tens of kilometers. Therefore you can cover a large area with one unit and lots of sensors, and measure without additional equipment and without power connections to all monitored locations.
No calibration or determining of new zero
The wavelength reflected by each FBG is modulated by the measured quantity, for example strain. The system measures this reflected wavelength which is an absolute parameter. Hence you can turn off or replace the instrument without having to recalibrate it or reset the zero level.
