PURPOSE: A wireless instrumentation system of micro vibration structure utilizing active sensor module is provided to evaluate the aging and deformation of a micro vibration structure. CONSTITUTION: A wireless instrumentation system of micro vibration structure comprises an active sensor module(100), a wireless data logger(200), and a wireless data receiver(300) and a data analysis part(400). The active sensor module is installed in the same coplanar as the specific location of structure according to stratification or location. The active sensor module analyzes the acceleration data measured by two acceleration sensors. The wireless data logger wirelessly transmits the data measured from a plurality of active sensor modules. The wireless data receiver receives the data transmitted through the wireless data logger. The data analysis part compares the extracted intrinsic value and native mode to the existing intrinsic value and native mode. The data analysis part evaluates the aging and deformation of a structure.
