Due to a lack of suitable process technology, insufficient consideration has been paid to the time factor during monitoring of structures. Time cycles such as seasons, weekdays, daytime, night time, high and low tides, drive-shaft rotation and natural oscillations leave a mark on the structure. These cycles can range in duration from a few fractions of second to several years, and usually overlap.
The OSMOS system is the first of its kind to permit complete and continuous structural diagnostics. It registers the entire history of a structure to allow comprehensive analyses. This is achieved through continuous recordings of static and dynamic stress cycles such as tensions, deformations and displacements. Even in the event of a power failure, the integrated reference variable prevents a loss of orientation; thus permitting a correct resumption of recording of measured data following a restoration of power.
Sparodic measurements on structures provide data at ‘apparently’ important points in time. This intermittent data acquisitions are used as a basis for drawing conclusions which can be highly erroneous. Consequently, this type of data acquisition is not suitable for reliable forecasts concerning structural behaviour. Knowledge of the entire history of a structure makes it possible to identify and analyze periodic events. This permits a better evaluation of the acquired data. As the period of observation lengthens, an increasing amount of knowledge becomes available to the user, thus resulting in a continuous learning curve. This allows accurate forecasts of future structural behaviour as well as precise risk estimates. Structures can be observed objectively with continuous data readings. Only a continuous monitoring of structural loads and stress cycles reflects actual structural characteristics.
