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

摘要

The present invention relates to a distributed data collection system which suppresses noise which interferes in collected data by shortening a length of a signal line of sensors attached to a large blade, wherein time synchronization of detection data is applied, and a data collection method capable of safely collecting and storing data. According to the present invention, the distributed data collection system comprises: a plurality of sensors arranged on a surface or the inside of the blade to be separated and detecting a physical quantity generated as a test load is applied; two or more distributed data collection devices arranged in order for a length of the signal line of the sensors arranged to be adjacent to become short; and a data storage device storing the detection data collected by the distributed data collection device.
