Patent ID: 8718831

Claim:
A method for monitoring operating parameters of a blade of a wind turbine having at least one strain sensor and a data acquisition device operatively coupled to the at least one strain sensor, said method comprising: supplying power to the data acquisition device, the data acquisition device configured to receive the power generated at the blade by at least one of a vibration of the blade and a pressure change across the blade; supplying power to the at least one strain sensor from the data acquisition device; sensing, by the at least one strain sensor, strain data associated with the blade; transferring the strain data from the at least one strain sensor to the data acquisition device; converting, by the data acquisition device, the strain data to digital strain data; transmitting, through radio frequency (RF) transmission, the digital strain data from the data acquisition device to an RFID reader; storing the transferred strain data in a computer; and analyzing the stored strain data to determine the strain on the blade.
