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

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 s...

Beschreibung
Zusammenfassung:	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. La présente invention concerne un système d'acquisition de données réparti, dans lequel des lignes de signaux de capteurs fixés à une pale de grande taille sont raccourcies afin d'empêcher le bruit d'être inclus dans les données acquises, et dans lequel des données ont une synchronisation temporelle, et un procédé d'acquisition de données pouvant acquérir et de stocker des données en toute sécurité. Le système d'acquisition de données réparti selon la présente invention comprend : au moins deux dispositifs d'acquisition (200) de données répartis arrangés de façon répartie sur la pale (10) de turbine éolienne ; et au moins deux capteurs disposés de façon répartie sur une surface ou à l'intérieur de la pale et reliés aux dispositifs d'acquisition répartis adjacents à l'aide d'un fil de signal.
