Blade, which is scratched, scratches away from, blade torque, blade tip offset, pylon away from one of, structural vibration, 3 D motion trace or a variety of；
6) in the case where the commissioning device of the sensor is in operating status, to each uneven parameter of all the sensors acquisition into
The analysis of row system value, including calculating standard deviation, root-mean-square error, low frequency and the opposite variation of high frequency, low frequency and high frequency are absolute
Change, relative to the peak valley distance moved horizontally, selectes the sensing most with the uneven parameter error of other sensors acquisition
Device is sensor subject to registration；
7) each uneven parameter collected of the other sensors in addition to the sensor subject to registration is subjected to system value
Analysis, including calculate standard deviation, root-mean-square error, the opposite variation of low frequency and high frequency, low frequency and high frequency absolute change, relative to
The peak valley distance moved horizontally carries out parameter to the sensor subject to registration according to the result of system value analysis and matches
It is quasi-.
