Teleco’s novel SHM602 system has been developed in partnership with the Interdepartmental Centre for Buildings and Construction at Bologna University and offers real-time monitoring of structural integrity of structures. This system operates on the basis of dynamic models obtained by means of identification techniques from accelerometric measures performed on the structure to be monitored. It relies on advanced measure, filtering and identification techniques and allows a real-time remote access to all data
Advanced features of the SHM602 allow filtering and modelling operations to be performed inside every measuring unit, the use of robust and reliable MEM sensors. The use of a digital bus allows non-invasive and reliable implementation on large structures where traditional analogue systems would require expensive and invasive radial connections and auxiliary hardware to limit signal deterioration over distance. s that must be
The smart architecture of the connection network allows the construction of global models suitable for detecting possible problems in the points where the sensors have been allocated and also in interconnecting substructures. Another important task performed by the computational resources allocated inside every sensing unit concerns the real-time monitoring of the correct performance of every sensor and the automatic exclusion of faulty sensors.
The SHM602 is a modular system and can be configured as required to optimise cost and performance. The SHM602 includes software packages allowing the configuration of the sensor network, data acquisition and storage, and real-time modal analysis of the monitored structures. It can operate both on structures affected by factors such as vehicle traffic, wind or seismic events.
A significant test on the SHM602 has been recently performed on the Manhattan Bridge, New York City, as part of a joint project between Columbia and Bologna Universities. The unit I said to be robust and able to cope with long use in difficult applications.
