Nowadays bridges getting longer spans and more complex geometries. Design assumptions used in the calculation models result in simplification of the object load scheme in real conditions. So they represent only an approximation of actual construction behaviour. To obtain reliable data about the physical values influencing the object, we created the monitoring system of bridge structures called Inspector Bridge. It includes sensors for measuring physical quantities such as force, strain, vibration, temperature, angular deflection or weather conditions. The data recorded by the sensors is sent to local servers and further on forwarded to the global server. Software is unique and dedicated for each project. It enables effective integration of sensors, as well as the data transfer in a user-readable example via the web interface. Thanks to the innovation and high-quality services, we became the market leader in monitoring of bridge structures in Poland.
