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

摘要

The present invention relates to a distributed data acquisition system, in which signal lines of sensors attached to a large-sized blade are shortened to prevent noise from being included in acquired data, and in which data is given time-synchronization, and to a data acquisition method capable of safely acquiring and storing data. The distributed data acquisition system according to the present invention includes: at least two distributed data acquisition devices(200) distributedly arranged on the wind turbine blade(10); and at least two sensors distributedly arranged on a surface or inside of the blade and connected to the adjacent distributed acquisition devices with a signal wire.
