Portable bridge structures control system

based on products of ZETSENSOR series

Nowadays one can hardly imagine a large town without a single bridge in it. The bridges simplify modern life by saving our time, but they are also a place of sightseeing in many well-known cities.

However, modern bridges are exposed to considerable loads and stresses caused by a great variety of factors (traffic load, climatic factors, seismic environment), which finally lead to bridge structure deformation.

Thus, there arises the need to perform constant monitoring of the structure, to measure its dynamic characteristics and to evaluate its residual life. All this allows to take timely measures to eliminate the defects and to increase the safety of bridges operation as well as to cut the costs for their full-scaled refurbishment.

Portable bridge structures control system based on digital sensors of ZETSENSOR series enables performance of bearing structures comprehensive diagnostics, which includes:

  • bridges bearing structures stress-strain state monitoring;
  • acceleration and vibration monitoring and evaluation;
  • calculation and control of dominant modes and maximum oscillations amplitude of the structures.

Operating principles

of portable bridge structures control system

Portable bridge structures control system is a set of digital modules and intelligent sensors placed inside of a compact case. Basic delivery scope of the system includes:

In the case of simultaneous use of 3-4 recorders it is possible to create distributed data acquisition and bridges bearing structures systems. The data acquisition systems enable acquisition of the information concerning change of the operational mode or repair works. These preventive measures enable cost-cutting without the necessity to perform refurbishment works.

Task – oriented software enables visual representation of the data obtained at operator’s display. The data can be represented in graphical or digital format depending on Customer’s requirements.

The standard software for visual representation of the data is supplied together with portable system for bridges structures monitoring – the multi-channel measurements system.

Depending on Customer’s request the software can be supplemented with other programs from ZETLAB scope or with ZETVIEW SCADA-system for the purpose of user-friendly interface development.
