Summary

Experimental identification of structural dynamics properties of large civil engineering structures usually involves application of long signal cables during the experiment. Such cables are heavy, difficult to handle and to be laid by testing engineers, as well as they are often damaged during use. That is why recently more and more often wireless sensors have been applied in modal testing of large civil engineering structures. Authors tested application of Mica2 modules with TinyOS software for PC in measurement system. Possibility of application of GPS synchronisation of measurement of multiple MEMS accelerometers was also studied. Authors present a short description of results of testing of a prototype of the developed wireless vibration measurement system in laboratory and field. The indications for future improvement of the prototype system are discussed
