DATA ACQUISITION SYSTEM AND DATA ACQUISITION METHOD FOR TESTING OF WIND TURBINE BLADE

摘要

The present invention relates to a data acquisition method which can restrain an intervention of noise in acquired date by shortening a signal line of sensors attached to a large blade, and enables safely acquiring and saving dispersed-type data acquisition system and data given with a time synchronization of detected data. According to the present invention, the dispersed-type data acquisition system comprises: a plurality of sensors detecting physical quantity generated due to an infliction of test load by being dispersed and disposed on a surface of the blade or inside thereof; at least two dispersed-type data acquisition apparatus disposed to be shorten in length of the signal lines of the sensors disposed nearby; and a data saving apparatus saving detected data acquired from the dispersed-type data acquisition apparatus.
